Description

COMBINE

The present invention relates to a combine having a harvesting unit provided at the front of the body for harvesting grain for planting in a package.

In addition, the present invention relates to a combine having a driver's seat, a harvesting unit provided in front of the driver's seat and capable of swinging up and down between a lower working position for harvesting grain in planting rows and an upper non-working position for not harvesting grain in planting rows, and a threshing device provided in the rear of the harvesting unit for threshing the harvested grain rows.

The self-propelled combine harvester is equipped with a pair of crawler-type driving devices on the left and right sides mounted on the lower part of the body, a cutting section supported on the front end of the body, and a threshing section mounted on the upper part of the body, and performs cutting work while driving the body. However, since this work often takes place at dusk and it becomes difficult to steer the platform in the cockpit, a headlight is provided to illuminate the front.

For example, Patent Document 1 discloses a combine having headlights provided at both ends of a harvesting section. In this combine, side covers are provided on the left and right of a standing device provided on the harvesting section, and two headlights are provided side by side in the upper part of each of the two side covers. These headlights are configured such that a halogen light as a light source and a reflector part that reflects light from the halogen light are built into a headlight opening provided at a predetermined position in the side cover, and a large light-emitting cover part is provided to cover the headlight opening.

In addition, as a combine as described above, for example, a combine described in Patent Document 2 is already known. Patent Document 2 discloses a combine which is provided with a driver's seat ("driver's seat [4]" in the document), a reaping unit ("reaping unit [3]" in the document) which is provided in front of the driver's seat and can swing up and down between a lower working position where reaping work is performed in a planted grain row and an upper non-working position where reaping work is not performed in a planted grain row, and a threshing device ("threshing device [5]" in the document) which is provided in the rear of the reaping unit and threshing the reaped grain row.

The reaping section has a plurality of reaping devices (in the document, "reaping devices [73]") for dividing the planted grain stalks, an erecting section for erecting the planted grain stalks divided by the reaping devices, and a returning device for returning the reaped grain stalks rearward toward a threshing device. The rising section has a plurality of reaping devices (in the document, "reaping devices [13]") for erecting the planted grain stalks, and an erection drive shaft (in the document, "counter shaft [41]") that extends along the left-right direction of the body over the upper portions of the plurality of reaping devices and transmits driving force to each of the plurality of reaping devices. According to the combine described in patent document 2, after the planted grain stalks are reaped, the ear tip side of the grain stalk is lifted by the erecting devices, and the reaped grain stalks are returned rearward toward a threshing device by the returning device.

Japanese Patent Publication No. 2006-006319 Japanese Patent Publication No. 2008-61572

These combines have a configuration in which the headlights are supported on the side covers and the wiring of the headlights is done after the side covers are installed on the preview frame. Therefore, there was a problem in that the headlight wiring had to be re-done every time the side covers were attached or removed, making the work cumbersome.

The present invention has been made in consideration of the above circumstances, and aims to provide a combine having a good maintainability of a harvesting unit.

In addition, since these combines are configured such that the headlight or floodlight cover is supported by the side cover, when a failure occurs in the side cover, headlight, or floodlight cover, it is necessary to disassemble and replace the entire unit.

The present invention has been made in consideration of the above circumstances, and aims to provide a combine that can be easily replaced when the side cover or headlight breaks down.

In addition, since the two headlights provided on the left side cover are supported in an installation position inclined outward toward the left side at an angle of about 15 degrees with respect to the forward-backward direction of the aircraft, and the two headlights provided on the right side cover are supported in an installation position inclined outward toward the right side at an angle of about 15 degrees with respect to the forward-backward direction of the aircraft, there is a problem that although the outer side of the cutting width of the cutting section is illuminated, it is difficult to recognize the growth status of the grain row immediately before the cutting section, which is the target of cutting, or the status of the packaging.

The present invention has been made in consideration of the above circumstances, and has as its object the provision of a combine harvester equipped with a headlight that makes it easy to recognize the growth status of a grain culm or the state of a field immediately before the harvesting section, which is the target of harvesting.

Here, in the case of long stems (long stems), since the upper and lower positions of the top of the stem are high, when the harvested stem is returned backwards toward the threshing device by the return device, the top of the stem may get caught on the upper part of the standing part. And, when the top of the stem gets caught on the upper part of the standing part, the posture of the stem during the return becomes disturbed, which causes the return to become blocked.

In view of the above circumstances, a combine is desired in which the ear tip portion of the grain is unlikely to get caught on the upper part of the standing part when the forehand grain is returned backwards toward the threshing device by the return device.

In order to achieve the above-described object, the characteristic configuration of the combine according to the present invention is that it is a combine having a reaping section which is provided at the front part of the body and reaps grain rows for planting, the reaping section having an erecting device which erects the grain rows for planting, a reaping frame which supports the erecting device, side covers which are provided on each of the left and right sides of the erecting device, a headlight cover which is arranged in a cover opening provided in each of the side covers, a light unit which constitutes a headlight which is arranged in a headlight opening provided in the headlight cover, and a headlight bracket which allows the headlight cover and the light unit to be individually detachable, and the headlight bracket is supported by the reaping frame.

According to the above-described configuration, the light unit and headlight cover constituting the headlight are not supported by the side cover, but the headlight bracket with the light unit and headlight cover constituting the headlight installed is installed on the preview frame. Therefore, since only the side cover can be attached and detached while the light unit is wired, maintainability is good.

In addition, the term “opening” in the present invention is used in a broad sense, and includes “hole” or “cut”.

In the present invention, a plurality of headlight openings are provided at positions spaced apart in the vertical direction in the headlight cover, one light unit is arranged in each of the headlight openings, and it is preferable that the headlight bracket be capable of individually detaching each light unit.

According to the above-described configuration, since the multiple light units are individually removable from the headlight bracket, only some of the light units can be replaced.

In the present invention, it is suitable if the opening size of the opening for the headlight is configured to be larger than the outer diameter size of the light unit.

According to the above-described configuration, since the light unit can be installed or removed only through the headlight opening while the headlight bracket is installed on the preview frame, the light unit can be easily replaced. It is preferable that the opening size of the headlight opening be larger than the outer diameter of the light unit to allow the light unit to pass through.

In the present invention, it is preferable that the headlight cover has a flange portion that can be hung and supported on the back surface of the main portion of the opening for the cover.

According to the above-described configuration, when the side cover is installed as if it were put on the headlight cover, the flange portion is supported by being hooked on the back surface of the periphery of the cover opening, and the headlight cover is automatically positioned with respect to the cover opening of the side cover. In addition, if there is a large gap between the cover opening and the headlight cover, there is a risk that grain may enter the side cover from this gap, but this can be prevented by providing the flange portion. The flange portion may be provided over the entire periphery of the headlight cover, or may be provided on a portion of it. In addition, since the headlight cover is configured to be hooked and supported on the back surface of the periphery of the cover opening, the side cover is provided outside the headlight cover. Therefore, by removing the side cover while the headlight cover is installed, the periphery of the first headlight or the second headlight can be widely opened, so that the workability of maintenance is improved.

In addition, a characteristic configuration of a combine according to the present invention for achieving the above-described purpose is that a combine is provided with a reaping section which is provided at the front of the body and reaps a grain row for planting a package, the reaping section is provided with an erecting device which erects the grain row for planting, and side covers which are provided on each of the left and right sides of the erecting device, and on the upper part of each of the side covers, a cover opening facing at least toward the front of the body is provided, a headlight cover is arranged in the cover opening, and in the headlight cover, a first headlight opening positioned at the top and a second headlight opening positioned at the bottom are provided at positions spaced apart in the vertical direction, and a first headlight is arranged in the first headlight opening, and a second headlight is arranged in the second headlight opening.

According to the above-described configuration, since the first headlight and the second headlight are individually positioned at vertically separated positions in the headlight cover, the first headlight and the second headlight, the headlight cover, and the side cover can each be replaced as individual parts.

In addition, the term “opening” in the present invention is used in a broad sense, and includes “hole” or “cut”.

In the present invention, the first headlight and the second headlight are each configured as a light unit integrally including a light source portion that emits light, a reflector portion that reflects light irradiated from the light source portion, and a light-emitting cover portion that covers the reflector portion, and it is preferable that the first light-emitting cover portion of the light unit constituting the first headlight and the second light-emitting cover portion of the light unit constituting the second headlight are arranged so as to protrude forward in the light irradiation direction more than the first opening edge of the opening portion for the first headlight and the second opening edge of the opening portion for the second headlight.

According to the above-described configuration, since the first headlight and the second headlight are configured as light units, they can be configured to be individually detachable from the side cover, and thus, compared to a configuration in which the side cover has a light-emitting cover portion and a light source portion and a reflector portion are arranged inside it, maintainability is excellent. In addition, since the work target range can be reduced when replacing parts, maintainability is further improved.

In a conventional configuration where a large light-emitting cover portion is provided on the side cover and a light source portion and a reflector portion are arranged inside it, the larger the area of the light-emitting cover portion, the easier it is for the tips of the ears of the planting season to come into contact with them, or for straw chips or dirt to adhere to them. In contrast, according to the configuration described above, since the light-emitting cover portion is provided for each light unit, the area of the light-emitting cover portion can be made narrow, reducing the risk of the tips of the ears of the planting season coming into contact with them, or for straw chips or dirt to adhere to them. In addition, since the light-emitting cover portion is arranged to protrude forward in the direction of light irradiation rather than at the corner of the opening, there is no case where the light is obscured by the headlight cover.

In the present invention, it is preferable that the first headlight be positioned so that the light-emitting portion of the first headlight is positioned further inward in the width direction of the body than the light-emitting portion of the second headlight.

According to the above-described configuration, even if the crops are tall, the inside is illuminated by the first headlight, which is positioned higher than the second headlight and is unlikely to form a shadow of the planted grain stalk, and the outside is illuminated by the second headlight, which is positioned lower than the first headlight and may form a shadow of the long stalk if illuminated from the front. By making good use of the difference in height between the first headlight and the second headlight, the field can be illuminated efficiently without any residue.

In the present invention, it is preferable that a first inclined surface be provided at a lower front side of the opening for the first headlight in the headlight cover and directed downwards further forward than the direction of the optical axis of the first headlight, and a second inclined surface be provided at a lower front side of the opening for the second headlight in the headlight cover and directed downwards further forward than the direction of the optical axis of the second headlight.

According to the above-described configuration, it is difficult for straw chips or dirt to accumulate on the headlight covers in front of the first and second headlights.

In the present invention, it is suitable if the second inclined surface is further forward and downward than the first inclined surface.

According to the above-described configuration, the optical axis of the second headlight can be directed lower than the optical axis of the first headlight, and by the second headlight being located closer to the package than the first headlight, the part close to the airframe can be reliably brightly illuminated.

In the present invention, it is preferable that a first sunshade-shaped portion is provided at a front upper portion of the opening for the first headlight in the headlight cover, so as to protrude further forward of the body than the light-emitting portion of the first headlight, and a second sunshade-shaped portion is provided at a front upper portion of the opening for the second headlight in the headlight cover, so as to protrude further forward of the body than the light-emitting portion of the second headlight.

According to the above-described configuration, since the first headlight and the second headlight are covered at the upper front by the presence of the first visor-shaped portion and the second visor-shaped portion, it is difficult for rainwater or moisture attached to the side cover to adhere to the light-emitting portion, and thus a situation in which straw chips or dirt are attached due to grain coming into contact with the wet light-emitting portion can be prevented.

In the present invention, it is preferable that the first visor-shaped portion and the second visor-shaped portion are configured in a shape that extends upwardly from the inner portion in the width direction of the body to the outer portion while being at the rear of the body.

According to the above-described configuration, the first visor-shaped portion or the second visor-shaped portion covers and protects the front upper portion of the first headlight or the second headlight, while not obstructing the light projection from the first headlight or the second headlight. Since the grain is smoothly guided upward at the rear of the fuselage along the first visor-shaped portion or the second visor-shaped portion, the risk of detachment is reduced.

In the present invention, it is preferable that a first vertical wall portion be provided on the inner side of the first headlight opening in the body width direction of the headlight cover, which extends up and down along the surface of the side cover and connects to the inner side of the body width side of the first sunshade-shaped portion, and that a second vertical wall portion be provided on the inner side of the second headlight opening in the body width direction of the headlight cover, which extends up and down along the surface of the side cover and connects to the inner side of the body width side of the second sunshade-shaped portion.

According to the above-described configuration, the first headlight is continuously surrounded by the first slope, the first awning-shaped portion, and the first vertical wall portion, and the second headlight is continuously surrounded by the second slope, the second awning-shaped portion, and the second vertical wall portion. Therefore, it is difficult for the tip of the ear of the standing grain to contact or get caught on the first headlight or the second headlight. Therefore, detachment is prevented.

In addition, a characteristic configuration of a combine according to the present invention for achieving the above-described purpose is a combine having a reaping section provided at the front of the body for reaping a grain row for planting a package, the reaping section is provided with an erecting device for erecting the grain row for planting, and side covers provided on each of the left and right sides of the erecting device, and on the upper portions of each of the side covers, a first headlight and a second headlight capable of irradiating the front of the body are arranged vertically side by side with the first headlight positioned above the second headlight, and the optical axis of the first headlight is configured to face further inward in the width direction of the body than the optical axis of the second headlight.

Since the first headlight is positioned higher than the second headlight, its light is less likely to be obscured by the tips of the ears of the planting row. By aligning the optical axis of the first headlight to face inward in the width direction of the body than that of the second headlight, it becomes easier to see the growth status of the planting row immediately before the cutting target and the state of the field by the first headlight.

In the present invention, it is preferable that the optical axis of the first headlight be configured to face inward in the width direction of the body rather than the front of the body, and that the optical axis of the second headlight be configured to face outward in the width direction of the body rather than the front of the body.

According to the above-described configuration, the first headlight can mainly illuminate the inner side in the width direction of the fuselage rather than the front of the fuselage, and the second headlight can mainly illuminate the outer side in the width direction of the fuselage rather than the front of the fuselage. Therefore, the overlapping of the illumination ranges of the first headlight and the second headlight is small, and illumination can be provided over a wide area.

In the present invention, it is preferable that the first headlight be positioned so that the light-emitting portion of the first headlight is positioned further inward in the width direction of the body than the light-emitting portion of the second headlight.

According to the above-described configuration, even if the crops are tall, the inside is illuminated by the first headlight, which is positioned higher than the second headlight and is unlikely to form a shadow of the planted grain stalk, and the outside is illuminated by the second headlight, which is positioned lower than the first headlight and may form a shadow of the long stalk if illuminated from the front. By making good use of the difference in height between the first headlight and the second headlight, the field can be illuminated efficiently without any gaps.

In the present invention, it is preferable that the second headlight be arranged so that the optical axis of the second headlight faces lower than the optical axis of the first headlight.

According to the above-described configuration, the first headlight, which is positioned higher than the second headlight, can illuminate a distant area in front of the aircraft, and the second headlight, which is positioned closer to the pavement than the first headlight, can clearly illuminate a portion close to the aircraft.

In the present invention, it is preferable that a division hole for dividing the grain space is provided at each of the left and right ends of the above-mentioned pre-harvesting section, and at least one of the above-mentioned first headlight or the above-mentioned second headlight is configured to illuminate at least a part of the division hole.

According to the above-described configuration, since at least a part of the dividing line, preferably the tip, is illuminated by either the first headlight or the second headlight, it is easy to recognize the boundary between the target planting row and the target seeding area, or the boundary between the target planting row and the non-targeting seeding area.

In the present invention, it is preferable that the first headlights on the left and right be arranged so as to illuminate the front of the aircraft across the entire width of the preview width of the preview section.

According to the above-described configuration, since the front of the aircraft is illuminated across the entire width of the cutting width of the cutting section by the first headlights on the left and right, it is easy to recognize the growth status of the planted grain rows within the cutting width and the status of the packaging.

In the present invention, it is preferable that the first headlight and the second headlight are each configured as a light unit integrally including a light source portion that emits light, a reflector portion that reflects light irradiated from the light source portion, and a light-transmitting cover portion that covers the reflector portion.

According to the above-described configuration, since the first headlight and the second headlight are configured as light units, they can be configured to be individually detachable from the side cover, and thus, compared to a configuration in which the side cover has a light-emitting cover portion and a light source portion and a reflector portion are arranged inside it, maintainability is excellent. In addition, since the work target range can be reduced when replacing parts, maintainability is further improved.

In the present invention, it is suitable if the first headlight and the second headlight are positioned in a state where the light-transmitting cover is exposed to the front of the aircraft.

In a conventional configuration where a large light-emitting cover part is provided on the side cover and a light source part and a reflector part are arranged inside it, the larger the area of the light-emitting cover part, the easier it is for the tips of the ears of the planting grain to come into contact with them, or for straw chips or dirt to adhere to them. In contrast, according to the configuration described above, since the light-emitting cover part is provided for each light unit, the area of the light-emitting cover part can be made narrow, and there is less concern that the tips of the ears of the planting grain will come into contact with them, or that straw chips or dirt will adhere to them.

In the present invention, the light source unit is preferably an LED module.

According to the above-described configuration, the power generation efficiency is higher than that of incandescent bulbs such as halogen lamps, so it has low heat generation and a long lifespan.

In the present invention, it is preferable if the two-light state in which the first headlight and the second headlight are turned on are configured to be switchable, and the one-light state in which only one of the first headlight or the second headlight is turned on.

According to the above-described configuration, for example, when performing preparatory work, the workability is improved by illuminating a wide area with the first headlight and the second headlight, and when driving on the road, energy is saved by illuminating only with either the first headlight or the second headlight.

In another embodiment,

The features of the present invention are:

A driver's seat with a driver's seat,

A cutting unit is provided in front of the above driving unit and is capable of swinging up and down between a lower working position where cutting work is performed in the planting grain row and an upper non-working position where cutting work is not performed in the planting grain row.

A combine equipped with a threshing device for threshing the grain in the foregoing section, which is installed at the rear of the foregoing section.

The above-mentioned harvesting unit has a plurality of division units for dividing the planting grain, an erecting unit for erecting the planting grain divided by the division units, and a return device for returning the harvested grain to the rear toward the threshing device.

The above-mentioned standing part has a plurality of standing devices that act as standing devices between the planting grains, and an standing drive shaft that extends along the left-right direction of the body over the upper portions of the plurality of standing devices and transmits driving force to each of the plurality of standing devices.

In a state where the above-mentioned pre-loading part is located at the working position, the standing drive shaft is at a point that protrudes toward the opposite side of the driver's seat with respect to a straight line connecting the viewpoint of a driver seated in a normal posture on the driver's seat and the tip of the minute tool as viewed from the side.

In this feature configuration, when the pre-flight unit is positioned at the working position, the standing drive shaft protrudes toward the opposite side of the driver's seat with respect to a straight line (hereinafter simply referred to as "straight line") connecting the viewpoint of a driver seated in a normal posture on the driver's seat and the tip of the minute tool as viewed from the side. Here, if the standing drive shaft is positioned on the driver's seat side with respect to the straight line when the pre-flight unit is positioned at the working position, the standing drive shaft approaches the inside of the fuselage in the forward-rear direction of the fuselage. For this reason, when the vertical position of the standing drive shaft is raised, it is easy to be restricted in space by surrounding members, and it is difficult to raise the vertical position of the standing drive shaft.

However, according to this feature configuration, when the pre-positioning part is positioned at the working position, since the standing drive shaft protrudes in the opposite direction from the driver's seat with respect to the straight line, the standing drive shaft approaches the outside of the aircraft in the forward-rearward direction of the aircraft. As a result, when the vertical position of the standing drive shaft is raised, it is difficult to be restricted by space due to surrounding members, and it is easy to raise the vertical position of the standing drive shaft.

And, by raising the vertical position of the standing drive shaft, the vertical position of the upper part of the standing part becomes higher, and as a result, when the grain stalk is returned backward toward the threshing device by the return device, it becomes difficult for the ear end part of the grain stalk to get caught on the upper part of the standing part.

In addition, in the present invention,

It is suitable if, when the above-mentioned pre-positioned part is positioned at the working position, the line of sight of the driver seated in the driver's seat in the normal posture toward the tip of the minute ball is blocked by the upper part of the standing part.

According to this feature configuration, when the upper part of the standing part is positioned at the working position to a position where the driver, seated in the driver's seat in a normal posture, can see the tip of the minute ball, the standing drive shaft protrudes in the opposite direction from the driver's seat with respect to the straight line. As a result, the standing drive shaft comes closer to the outside of the aircraft in the forward-rearward direction, making it much easier to raise the vertical position of the standing drive shaft.

In addition, in the present invention,

The above-mentioned standing part has a cover member that extends along the standing drive shaft and covers the standing drive shaft from the front side,

It is suitable if, when the above-mentioned advance part is positioned at the working position, the line of sight of the driver seated in the driver's seat in the normal posture toward the tip of the minute tool is blocked by the cover member.

According to this feature configuration, when the cover member is positioned at the working position to a position where the driver, seated in the driver's seat in a normal posture, can see the tip of the minute sphere, the standing drive shaft protrudes in the opposite direction from the driver's seat with respect to the straight line. As a result, the standing drive shaft comes closer to the outside of the aircraft in the forward-reverse direction, making it much easier to raise the vertical position of the standing drive shaft.

In addition, in the present invention,

The above standing device has a plurality of standing hooks that move around its outer periphery,

When the above-mentioned pre-positioning part is positioned at the above-mentioned working position, it is suitable if the angle formed by the vertical line extending in the vertical direction and the movement trajectory of the above-mentioned standing hook as viewed from the side is set to 19.5 degrees or less.

According to this feature configuration, when the standing angle of the standing device is increased and the pre-positioning part is positioned at the working position, it becomes easy to protrude the standing drive shaft in the opposite direction to the driver's seat with respect to the straight line.

In addition, in the present invention,

A cabin covering the above driving section is provided,

When the above-mentioned pre-positioning part is positioned at the above-mentioned working position, it is suitable if the above-mentioned standing drive shaft is positioned further forward than the front end of the cabin.

According to this feature configuration, when the pre-fabricated part is positioned at the working position, the standing drive shaft protrudes in the opposite direction from the driver's seat with respect to the straight line to a position where the standing drive shaft is positioned further forward than the front end of the cabin. As a result, the standing drive shaft comes closer to the outside of the aircraft in the forward-rearward direction of the aircraft, making it much easier to raise the vertical position of the standing drive shaft.

The harvesting frame (11) of the harvesting unit (10) is oscillatingly connected around a horizontal axis with respect to the body (1). The harvesting unit (10) raises and lowers the harvesting frame (11) by expanding and contracting a lift cylinder (not shown), and can change its posture between a working posture and a non-working posture. The working posture is a posture in which the harvesting hole (12) and the harvesting blade (14), etc., are positioned at a height of about 1 cm to several cm from the package, as indicated by the solid line in Fig. 1, and the non-working posture is a posture in which the harvesting hole (12) and the harvesting blade (14), etc., are positioned higher than the height from the package in the working posture, as indicated by the dashed-dotted line in Fig. 1.

When the machine (1) is moved forward with the cutting unit (10) in the working posture, the planting grain rows are divided into cutting targets and non-cutting targets by the plurality of cutting slots (12), and the planting grain rows are divided into each group, so that the planting grain rows of the cutting targets are introduced into the standing path. In the present embodiment, as shown in Fig. 2, the cutting unit (10) is provided with seven cutting slots (12) and six standing devices, so that six-row cutting is possible. However, the cutting unit (10) is not limited to six-row cutting, and may be used for several-row cutting.

The grain from each hopper (12) is raised by the raising device (13) corresponding to each group and is harvested by the harvesting blade (14), and the harvested grain is returned to the threshing device (5) at the rear of the machine by the return device (15).

The threshing device (5) feeds the ear tip side of the planted grain to a feeding chamber (not shown) while supporting and returning the bottom side of the pre-harvested grain to the rear side of the machine by a threshing feed chain (not shown) to thresh the grain. The grain tank (6) collects and stores the threshed grain from the threshing device (5).

〔Side Cover〕

As shown in FIGS. 4 and 5, side covers (20) are detachably provided on each of the left and right sides of the cutting frame (11) of the cutting section (10) in the cutting width direction. Both the left and right side covers (20) are formed into a predetermined shape using a resin having mechanical strength and weather resistance, such as PP, PE, or ABS resin.

The front surface of either the left or right side cover (20) is an inclined surface that follows the front surface of the front of the fuselage of the standing device (13), and is positioned so that the upper surface is located closer to the rear of the fuselage.

Each side cover (20) on the left or right consists of a lower cover (21) and an upper cover (22) that is a separate part from the lower cover (21).

A lubricating oil tank (16) and a fuel pump (not shown) for each part of the pre-heating unit (10) are provided in a portion corresponding to the lower cover (21) of the pre-heating frame (11), and the lower cover (21) is configured to be easily attached and detached simply by switching a pair of engaging members provided on each of the pre-heating frame (11) and the lower cover (21) between an engaging state and an engaging release state in order to improve maintainability of the fuel tank (16), etc.

The upper cover (22) is provided with a concave portion (22a) that is formed inwardly from the outer surface of the lower cover (21) and is raised rearwardly along the upper end of the lower cover (21). In addition, a portion of the upper cover (22) that is higher than the concave portion (22a) protrudes outwardly from the outer surface of the lower cover (21).

The first headlight (31) and the second headlight (32) are provided in the bulged portion (22b) of the upper cover (22). Accordingly, the first headlight (31) and the second headlight (32) are provided in the upper portion of the side cover (20).

Specifically, as shown in FIGS. 6 to 10, the bulged portion (22b) of the upper cover (22) has an inclined surface facing the inclined rear of the body (1) from the inside to the outside when viewed in a plan view, and a vertically long cover opening (23) is provided on this inclined surface. In addition, the “opening” in this specification is used in a broad sense, and includes a “hole”, a “cut”, and the like.

A headlight cover (24) is placed in the opening (23) for this cover, and an opening (25) for a first headlight positioned on the upper side and an opening (26) for a second headlight positioned on the lower side are provided at positions spaced apart in the vertical direction in the headlight cover (24). The headlight cover (24) is formed by processing a resin having mechanical strength and weather resistance, such as PP, PE, or ABS resin, into a predetermined shape.

The opening (25) for the first headlight and the opening (26) for the second headlight are configured such that the opening dimensions of the opening (25) for the first headlight and the opening (26) for the second headlight are larger than the outer diameter dimensions of the first headlight (31) and the second headlight (32) so that the first headlight (31) and the second headlight (32) can pass through them.

〔Headlight〕

A first headlight (31) is placed in the opening (25) for the first headlight, and a second headlight (32) is placed in the opening (26) for the second headlight. Accordingly, the first headlight (31) and the second headlight (32) are individually placed side by side at positions spaced apart from each other vertically, with the first headlight (31) positioned above the second headlight (32).

The first headlight (31) and the second headlight (32) are each configured as light units integrally including a light source portion (not shown) that emits light, a reflector portion (not shown) that reflects light irradiated from the light source portion, a first housing portion (31A) and a second housing portion (32A) that accommodate the light source and the reflector portion, and a first light-transmitting cover portion (31B) and a second light-transmitting cover portion (32B) that cover the reflector portion. The first light-transmitting cover portion (31B) and the second light-transmitting cover portion (32B) are formed by processing a light-transmitting resin, for example, polycarbonate, into a predetermined shape.

Since the upper cover (22) is not provided with a light-transmitting cover portion that covers the entire surface of the cover opening (23), the first headlight (31) and the second headlight (32) are positioned with the light-transmitting portions, i.e., the first light-transmitting cover portion (31B) and the second light-transmitting cover portion (32B), exposed to the front of the aircraft.

In addition, the light source unit provided in the first headlight (31) and the second headlight (32) is an LED module, and it is preferably used to have an illuminance of about 1 lx (i.e., brightness of 625 cd) at a distance of 25 m, and an irradiation angle of about 30 to 35 degrees left and right, for example, 32 degrees, from the optical axis (31C, 32C), and also about 20 to 25 degrees up and down, for example, 22 degrees.

The first headlight (31) and the second headlight (32) illuminate so as to satisfy a brightness of 625 cd within the above-described range, but they do not illuminate only the above-described range, and they illuminate the periphery of the above-described range, although it does not fall within the above-described range. In FIGS. 11 and 12, the optical axis (31C) of the first headlight (31) and the optical axis (32C) of the second headlight (32) are indicated by solid lines, the range satisfying a brightness of 625 cd is indicated by a dotted line, and the range illuminated by the first headlight (31) and the second headlight (32) within the periphery of that range is indicated by a thin hatching.

As illustrated in Fig. 8, the first light-emitting cover portion (31B) of the light unit constituting the first headlight (31) and the second light-emitting cover portion (32B) of the light unit constituting the second headlight (32) are arranged so as to protrude forward in the light irradiation direction more than the first opening edge (25A) of the first headlight opening (25) of the headlight cover (24) and the second opening edge (26A) of the second headlight opening (26), respectively. Accordingly, the headlight cover (24) is configured not to block the light emitted from the first headlight (31) and the second headlight (32).

Since the first headlight (31) and the second headlight (32) are composed of light units, the upper cover (22) can be configured so that each light unit can be individually detachably attached, which provides good maintainability. In addition, since the first headlight (31) and the second headlight (32) are each provided with a first light-emitting cover (31B) and a second light-emitting cover (32B), the area of the first light-emitting cover (31B) and the second light-emitting cover (32B) can be narrowed, so there is less concern that the tips of the ears of grain between the planting grains will come into contact with each other or that straw chips or dirt will adhere to them.

In addition, the first headlight (31) and the second headlight (32) are configured to be switchable between a double-lighting state in which the first headlight (31) and the second headlight (32) are turned on, and a single-lighting state in which only one of the first headlight (31) or the second headlight (32) is turned on.

For example, when performing preparatory work, the workability can be improved by illuminating a wide area with the first headlight (31) and the second headlight (32), and when driving on the road, energy can be saved by illuminating only with either the first headlight (31) or the second headlight (32). In addition, the first headlight (31) and the second headlight (32) are configured so that both can be turned off.

〔Investigation direction and scope〕

As shown in FIGS. 11 and 12, the optical axis (31C) of the first headlight (31) is configured to face inward in the width direction of the body than the optical axis (32C) of the second headlight (32), and the optical axis (32C) of the second headlight (32) is configured to face outward in the width direction of the body than the optical axis (31C) of the first headlight (31). In addition, in the working state, the second headlight (32) is arranged so that the optical axis (32C) of the second headlight (32) faces downward than the optical axis (31C) of the first headlight (31). The first headlight (31) located at a higher position than the second headlight (32) can illuminate a distant area in front of the aircraft, and the second headlight (32) located closer to the pavement than the first headlight (31) can clearly illuminate an area close to the aircraft.

Specifically, the optical axis (31C) of the first headlight (31) is positioned so as to face inward in the width direction of the aircraft at an inclination angle of 5 degrees with respect to the front of the aircraft and toward the lower side of the aircraft (1) at an inclination angle of 3 degrees with respect to the front of the aircraft.

The optical axis (32C) of the second headlight (32) is positioned to face outward in the width direction of the aircraft at an inclination angle of 16 degrees with respect to the front of the aircraft and to face downward of the aircraft (1) at an inclination angle of 19.5 degrees with respect to the front of the aircraft.

Since the first headlight (31) mainly illuminates the inner side in the width direction of the fuselage rather than the front of the fuselage, and the second headlight (32) mainly illuminates the outer side in the width direction of the fuselage rather than the front of the fuselage, the overlap in the illumination ranges of the first headlight (31) and the second headlight (32) is small, and illumination can be provided over a wide area.

As illustrated in Fig. 6, the first headlight (31) is arranged so that the light-emitting portion of the first headlight (31), that is, the first light-emitting cover portion (31B), is positioned further inward in the width direction of the body than the light-emitting portion of the second headlight (32), that is, the second light-emitting cover portion (32B). Even if the crop is long, the first headlight (31), which is positioned higher than the second headlight (32) and is unlikely to form a shadow of the planted grain stalk, illuminates the inside, and the second headlight (32), which is positioned lower than the first headlight (31) and may form a shadow of the long stalk if it illuminates the front, illuminates the outside, thereby making good use of the fact that the heights of the first headlight (31) and the second headlight (32) are different vertically, so that the packaging can be illuminated efficiently without leaving any residue.

Since the first headlight (31) configured so that the optical axis (31C) faces more inward in the width direction of the aircraft is positioned higher than the second headlight (32), the light from the first headlight (31) is less likely to be obscured by the tip of the ear of the planted grain row, and it is easy to recognize the growth status of the planted grain row immediately before the cutting section, which is the target of cutting, and the status of the field. In addition, since the illumination range (31D) of the first headlight (31) is wider than the irradiation range (32D) of the second headlight (32), the planted grain row or field, which is the target of cutting, can be better illuminated.

The first headlights (31) on the left and right are arranged so that the front of the aircraft covers the entire width of the cutting width of the cutting section (10) by the illumination ranges (31D) on both sides. Since the front of the aircraft is illuminated over the entire width of the cutting width of the cutting section (10) by the first headlights (31) on the left and right, it is easy to recognize the growth status of the planted grain rows within the cutting width and the status of the field.

Since at least a part of the first headlight (31) or the second headlight (32), preferably the tip, of the first headlight (12) is illuminated, it is easy to recognize the boundary between the target planting row and the target seeding row, or the boundary between the target planting row and the target seeding row of the untargeted seeding row.

In another embodiment, since the first headlight (31) is positioned higher than the second headlight (32), its light is less likely to be obscured by the tip of the ear of the planting grain. By making the optical axis (31C) of the first headlight (31) face inward in the width direction of the body than the optical axis (32C) of the second headlight (32), the illumination range (31D) of the first headlight (31) faces inward in the width direction of the body than the irradiation range (32D) of the second headlight (32). By means of the first headlight (31), the growth state of the planting grain immediately before the reaping section (10) to be reaped can be easily recognized and the state of the field.

〔Headlight cover〕

As shown in FIGS. 6 to 8, the headlight cover (24) is provided with a first downwardly inclined surface (27A) that is forward and lower than the direction of the optical axis (31C) of the first headlight (31) at the front lower side of the opening (25) for the first headlight. Similarly, the headlight cover (24) is provided with a second downwardly inclined surface (28A) that is forward and lower than the direction of the optical axis (32C) of the second headlight (32) at the front lower side of the opening (26) for the second headlight. By providing the downwardly inclined surface at the front of the first headlight (31) and the second headlight (32), it is difficult for straw chips or dirt to accumulate on the headlight cover (24). Since the second inclined plane (28A) is further forward and downward than the first inclined plane (27A), the optical axis (32C) of the second headlight (32) can be directed downward than the optical axis (31C) of the first headlight (31), and the second headlight (32), which is located closer to the pavement than the first headlight (31), can certainly brightly illuminate a portion close to the body.

The headlight cover (24) is provided with a first sunshade-shaped portion (27B) that protrudes further forward of the body than the light-emitting portion of the first headlight (31), i.e., the first light-emitting cover portion (31B), at a front upper portion of the first headlight opening (25) in the headlight cover (24), and a second sunshade-shaped portion (28B) that protrudes further forward of the body than the light-emitting portion of the second headlight (32), i.e., the second light-emitting cover portion (32B), at a front upper portion of the second headlight opening (26) in the headlight cover (24). Since the first headlight (31) and the second headlight (32) are covered at the upper front by the presence of the first sunshade-shaped portion (27B) and the second sunshade-shaped portion (28B), it is difficult for rainwater or moisture attached to the side cover to adhere to the first light-transmitting cover portion (31B) or the second light-transmitting cover portion (32B), and thus, it is possible to prevent a situation in which the grain comes into contact with the wet first light-transmitting cover portion (31B) or the second light-transmitting cover portion (32B) and straw chips or dirt are attached to it.

The first sunshade shape portion (27B) and the second sunshade shape portion (28B) are configured to extend upwardly from the inner portion in the width direction of the body to the outer portion while being rearward of the body, so as to protect the front upper portion of the first headlight (31) or the second headlight (32) while not blocking the light projection from the first headlight (31) or the second headlight (32). Since the grain is smoothly guided upwardly at the rear of the body along the first sunshade shape portion (27B) and the second sunshade shape portion (28B), the risk of detachment is reduced.

In addition, the headlight cover (24) is provided with a first vertical wall portion (27C) extending up and down along the surface of the upper cover (22) on the inner side in the body width direction of the first headlight opening (25) in the headlight cover (24) and connecting to the inner side portion of the body width side of the first sunshade-shaped portion (27B), and a second vertical wall portion (28C) extending up and down along the surface of the upper cover (22) and connecting to the inner side portion of the body width side of the second sunshade-shaped portion (28B) is provided on the inner side in the body width direction of the second headlight opening (26) in the headlight cover (24).

Since the first headlight (31) is continuously surrounded by the first inclined surface (27A), the first awning-shaped portion (27B), and the first vertical wall portion (27C), and since the second headlight (32) is continuously surrounded by the second inclined surface (28A), the second awning-shaped portion (28B), and the second vertical wall portion (28C), the risk of contact between the ear tips of the planting grains is reduced. Since the ear tips of the planting grains are smoothly guided upward toward the rear of the fuselage along the first awning-shaped portion (27B), the first vertical wall portion (27C), the second awning-shaped portion (28B), and the second vertical wall portion (28C), the risk of detachment is reduced.

〔Headlight bracket〕

As shown in FIGS. 8 to 10, the headlight cover (24), the first headlight (31) and the second headlight (32) are provided on the bracket stay (17) of the pre-flight frame (11) through the headlight bracket (40).

The headlight bracket (40) is a member having a light stay (41, 42) from which the first headlight (31) or the second headlight (32) can be individually attached or detached, or a cover stay (43) from which the headlight cover (24) can be attached or detached. The headlight bracket (40), the light stay (41, 42), and the cover stay (43) are formed by processing a shape material made of a corrosion-resistant metal such as stainless steel into a predetermined shape. In addition, the light stay (41, 42) may be configured to support the light projection of the first headlight (31) or the second headlight (32) so as to be directionally adjustable.

Since the headlight cover (24) or the headlight bracket (40) with the first headlight (31) and the second headlight (32) installed is installed in the preview frame (11), it is configured so that only the upper cover (22) can be attached and removed while the first headlight (31) and the second headlight (32) are wired.

In addition, the headlight cover (24) has a flange portion (24A) that can be hooked and supported on the back surface of the periphery of the cover opening (23). When the upper cover (22) is installed as if it is put on the headlight cover (24), the flange portion (24A) is hooked and supported on the back surface of the periphery of the cover opening (23), and the headlight cover (24) is automatically positioned with respect to the cover opening (23) of the upper cover (22). There is no need to use screws to position the headlight cover (24).

In addition, if there is a large gap between the cover opening (23) and the headlight cover (24), there is a risk that grain may enter the upper cover (22) from this gap, but this can be prevented by providing a flange portion (24A). In addition, the flange portion (24A) may be provided over the entire circumference of the headlight cover (24) or may be provided on a portion thereof.

Since the upper cover (22) can be removed with the first headlight (31) and the second headlight (32) installed, when the upper cover (22) is separated from the preview frame (11), the light stays (41, 42) are exposed, so that the first headlight (31) or the second headlight (32) can be replaced, and therefore the maintainability is good.

The opening size of the opening (25) for the first headlight and the opening (26) for the second headlight are configured to be larger than the outer diameter of the first headlight (31) or the second headlight (32), and the first headlight (31) or the second headlight (32) can be individually attached or detached even when the headlight cover (24) is installed on the headlight bracket (40). The first headlight (31) or the second headlight (32) can be easily replaced. In addition, the replacement is performed in a state where the upper cover (22) is removed.

When installing the first headlight (31) and the second headlight (32) in the pre-flight unit (10), the first headlight (31) or the second headlight (32) is installed in the light stay (41, 42) of the headlight bracket (40), and then the headlight cover (24) is provided in the cover stay (43). This integrated headlight bracket (40) is installed in the bracket stay (17) provided in the pre-flight frame (11), and finally the upper cover (22) is installed. Disassembly is performed in the reverse order.

In addition, side lights or turn indicators may be arranged in parallel with the first headlight (31) and the second headlight (32) on the headlight cover (24). The side lights or turn indicators are also supported on the headlight bracket (40).

〔Arrangement structure of the standing drive shaft〕

In Fig. 17, a driver seated in a normal posture leaning rearward on the driver's seat (1004) is indicated as P1001, a driver seated in a normal posture leaning forward on the driver's seat (1004) is indicated as P1002, and a driver seated in a normal posture leaning forward on the driver's seat (1004) is indicated as P1003.

When the driver is seated on the driver's seat (1004) in the rearwardly tilted normal posture (P1001), the upright drive shaft (1042) protrudes toward the opposite side (i.e., the forward side) from the driver's seat (1004) with respect to the straight line (L1001) connecting the viewpoint of the driver seated on the driver's seat (1004) in the rearwardly tilted normal posture (P1001) and the tip of the minute sphere (1013) as viewed from the side.

In this case, the driver's line of sight (E1001) for viewing the tip of the minute sphere (1013) while seated in the rearward-leaning normal posture (P1001) on the driver's seat (1004) is obscured by the upper portion of the standing member (1014) (specifically, the standing horizontal stay (1040)). When the pre-positioning member (1007) is raised from the working position to the position drawn by the dashed line in Fig. 17, the driver can view the tip of the minute sphere (1013) while seated in the rearward-leaning normal posture (P1001) on the driver's seat (1004).

When the driver is seated on the driver's seat (1004) in the forward-leaning normal posture (P1002), the standing drive shaft (1042) is positioned on the driver's seat (1004) side (i.e., rearward) with respect to the straight line (L1002) connecting the viewpoint of the driver seated on the driver's seat (1004) in the forward-leaning normal posture (P1002) and the tip of the minute sphere (1013) as viewed from the side. In this case, the line of sight (E1002) of the driver seated on the driver's seat (1004) in the forward-leaning normal posture (P1002) looking at the tip of the minute sphere (1013) is obscured by the upper portion of the standing portion (1014) (specifically, the cover member (1030)).

When the driver is seated on the driver's seat (1004) in a forward-leaning posture (P1003), the upright drive shaft (1042) is positioned on the driver's seat (1004) side (i.e., rearward) with respect to a straight line (L1003) connecting the viewpoint of the driver seated on the driver's seat (1004) in a forward-leaning posture (P1003) and the tip of the minute sphere (1013) as viewed from the side. In this case, the line of sight (E1003) of the driver seated on the driver's seat (1004) in a forward-leaning posture (P1003) to see the tip of the minute sphere (1013) is not blocked by the upper part of the upright portion (1014). That is, the driver can see the tip of the minute sphere (1013) while seated on the driver's seat (1004) in a forward-leaning posture (P1003).

The standing drive shaft (1042) is positioned at a position forming an isosceles triangle, with the standing drive shaft (1042) as a vertex, and the length of a side corresponding to the movement trajectory (T100) of the standing hook (1032) and the length of a side corresponding to the axial center (Z1001) of the standing power case (1028) are approximately equal.
