Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a case where the stem culm is raised, the claw is raised, and the case is projected from the case to the side of the machine and is raised and transferred along the raising path, and is raised at the raising end. A stem culm raising device that is rotatably transferred to the descending return path is provided, and the stem culm from the stem culm raising device is laterally transferred in the direction in which the stem culm raising claws are raised and protrude from the case. The present invention relates to a stem culm raising portion structure of a cutting and harvesting machine in which a stem culm lateral feeding path is provided on the rear side of the stem culm raising device.

[Conventional technology]

In the above-mentioned harvesting machine, conventionally, for example, the actual exploitation Sho 63-9831
As shown in Japanese Patent Publication, when the culm is raised and the nail is made undulating, and when it is raised and reaches the terminal end, it is raised and laid down on the upper side in the moving direction and then retracted into the case. In many cases, the tip of the culm to be mowed is not easily caused by the fall of the stalk caused by the retracted stalk-causing nail and being caught in the case or scraped off by the nail fall.

[Problems to be solved by the device]

Conventionally, when the planting culm is lying or bent in the direction opposite to the direction in which the stem culm is raised and the nail is raised and protrudes from the case, even if it is in the raised state, it will fall or bend until then. The tip of the ear is raised and it is raised from the path and bent toward the case,
Due to the bending of the tip, the effect of lodging the nail was not sufficiently obtained, and the tip of the nail was sometimes caught or damaged by the raised nail.

The purpose of the present invention is to make it possible to effectively prevent the tip of the stem from being pulled up into the case, shredded, etc., regardless of the fallen or bent direction of the planting culm, and the structure is simple. It is to modify so that it can be obtained.

[Means for Solving the Problems]

According to a characteristic configuration of the present invention, in the stem culm raising part structure of the cutting and harvesting machine mentioned above, the lower end side and the upper end side of the operating part of the guide for stem and culm are located on the opposite side of the raising case from the raising case. A first attachment state in which a non-shearing target stem culm is pushed out to the lateral side of the fuselage at a position located on the lateral side of the fuselage, and the lower end of the operating portion is located in front of the raising case, and the upper end of the operating portion is located. The edge that guides the stem culm on the side is in a state of intersecting in a front view with the upper rim that raises the stem culm and locks the stem culm of the nail, and that the upper side is further away from the raise culm. Positioned in the raising path, the tip end side of the stem culm raised by the stem culm raising device is switchable to a second attachment state in which the stem culm is pushed out from the stem culm raising nail and pushed to the stem culm lateral feeding path. It is equipped with a culm guide. The action and effect are as follows.

[Action]

That is, when the planting stem culm is lying or bent in the direction in which the stem culm is raised and the nail is raised and protrudes from the case, the culm guide is set to the first mounting state. Then, the stem culm guide does not act on the stalks to be cut that are going to be cut out of the planted stalks, but even if the raised stalks are raised and the nails act,
Due to the lodging and bending up to that point, the tip part of the ear cane easily bends from the path to the lower side of the stalk lateral feed path, so that the tip part of the stalk to be cut spontaneously raises the stalk and slips off the nail. , Stem culm is moved to the stalk culm horizontal feeding path while being prevented from being caught or broken by the nails. The non-cutting culm that will be located in the uncut area on the lateral side of the fuselage that is not the target of cutting of the planted culm is placed on the inside of the raising device or the fuselage due to the lodging or bending in the direction. Even if it tries to get in, the culm guide pushes the culm to the lateral outer side of the machine body, and the non-crop target culm is raised and becomes less entangled with the device and the machine body part.

On the other hand, when the planting culm is lying or bent in the direction opposite to the direction in which the culm is raised and the claw is raised and protrudes from the case, the culm guide is placed in the second attached state. Then, although the guide for culm does not act on the non-crop target culm of the planted culms, the non-crop target culm is detached to the lateral side of the fuselage due to lodging or bending in the direction and the device is raised. It becomes difficult to be entangled with the body part. Then, even if the tip of the culm to be cut out of the planted culms is raised and bent in the path and bent toward the case side, the culm guide guides the culm so that the culms are raised and move away from the case. Forcibly extruded from the culm-raising claw to the stalk-horizontal feeding path, and the stalks to be cut are moved to the stalk-carcass lateral-feeding path while preventing the culm-raising and nails from being cut or broken.

[Effect of device]

Therefore, even if the falling direction or bending direction of the planted culm is the same as or opposite to the direction in which the culm is raised and the protruding direction of the nail, the cut object and the non-cut object of the planted culm are selected. A stem guide is applied to one side of the stem to prevent cutting and shredding of the target stem culm or non-shearing stem culm into the case by the raising claws and the machine part, and grain loss as much as possible. It became possible to work while preventing it.

Moreover, by using the stem culm guides for both the stalks to be cut and the stalks not to be cut, it is possible to simplify the structure so that there is no need for a pair of stalks to work separately. It was possible, and it was possible to construct it in terms of cost.

〔Example〕

As shown in FIG. 6, a planting stem culm is raised in front of the self-propelled aircraft having one traveling wheel (1), engine (E), steering handle (2), etc. as the aircraft travels. A walkable binder is provided as an example of a harvesting harvester by providing a working unit (A) for cutting and bundling the cut stems by a set amount.

A stem-and-bundle bundling device (6) is provided on the lateral end side of the plant, and the stalk-and-plucking device (4) and the stalk-and-cut culms from the reaping device (5) are packed into the stalk-and-bundle device (6). 7) The stem culm lateral feed path (R) which is vertically transferred by the stance and is supplied to the stem culm bundling device (6) is provided with a transfer guide plate (8) on the rear side of the stalk culm raising device (4). ) Is formed. Then, a stem culm guide (9) for preventing damage to the stalk by acting on the stalks to be cut or the stalks not to be cut is provided in the stalk-raising part.

The stem culm raising device (4) is constructed as shown in FIG.

That is, an endless chain (11) pivotally attached to a plurality of stem culm-raising claws (10) ... so that it can be undulated is driven to a tilting-raising case (12) that is located at a higher level toward the rear end side. It is movably decorated. Then, as the endless chain (11) is rotated, the stem culm is raised and the claw (10) is raised, and the case (1
At the lower end of 2), the tip end side is raised due to the standing guide (13), and it is in a standing posture protruding outside the case and locked to the stem culm from the fixed weeding tools (3a) and (3b), and raised. In the extension path (L), the upright guide rail (14) acts, the raising case (12) is located on the lateral side of the uplifting path (L) opposite to the binding device side, and the chain sprocket. Since the axis of rotation is in the front-back direction, the tip end side is raised toward the transfer direction in the stalk-side lateral feed route (R) and is maintained in a standing posture in the lateral direction of the machine body protruding from the case (12). The stalks to be mowed are picked up by being raised and transferred along the raising case (12) and the raising guide (15) in an upright posture. Then, when the stem culm raising claw (10) is raised and reaches the raising end of the case (12) at the upper end side, the standing guide rail (14) stops working and the stem culm raising resistance is caused. In addition, it is pulled up while being switched to the lying posture, retired into the case, and raised and is rotatably transferred to the descending return path (D) in the case.

The stem-culm guide (9) is made of a bent rod, and the fixed lower weeder (3a) on the device side is raised by raising the lower end side.
