Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an engine cover for a combine harvester in which the engine is located below the driver's seat.

(b) Prior Art Conventionally, a threshing device was mounted on one side of the machine base, and an operation control section consisting of an operation panel, operating steps, and a driver's seat was provided on the front part of the other side. A combine harvester is already known in which a grain culm pulling body on one side of a processing device is wrapped in front of one side of an operation panel, an engine is disposed below the driver's seat, and the engine is covered with an engine cover.

(c) Problems to be solved by the invention In the known combine harvester, when the pre-processing device is running, the triggering body must not interfere with the operation panel, and the grain tank must be installed behind the driver's seat. Since space is required and the overall length of the machine base needs to be as short as possible, the front and rear width of the operating steps is inevitably narrow, making it difficult to operate the travel clutch pedal located at the rear of the control panel.

The engine takes in air from the outside and exhausts it toward the thresher and forward, but this exhaust bypasses and heats the front part of the engine cover.
Added to this was the high heat from the engine itself, and since the engine cover was made of a single steel plate, the area corresponding to the driver's feet near the front of the engine cover became extremely hot.

(d) Means for solving the problem The present invention has a threshing device mounted on one side of the machine base, and an operating section consisting of a control panel, operating steps, and driver's seat on the front of the other side. In a combine harvester in which an engine is placed at the bottom of the engine, the front part of the engine cover that covers the engine is made into a double structure with two plates spaced apart by a narrow interval, and the lower side of the front part is bent rearward. The above-mentioned problems were solved.

(E) Function When operating the travel clutch pedal etc. on the back of the operation panel with your foot, the lower part of the front part of the engine cover slopes backward to create a wider space for the area corresponding to your heel, making it easier to operate the pedal. It is possible,
In addition, the front part of the engine cover has a double structure, which has good insulation properties, and is spaced apart from the feet, thereby reducing the temperature of the space where the feet are placed.

(F) Example An example of the present invention will be explained with reference to the drawings.
Like the conventional one, the threshing device is mounted on one side of the machine base 2 which has the traveling device 1, and on the other side of the machine base 2, at the front, there is a rear part separated from the operation panel 3 and the operation step 4. A driver's seat 5 is provided, and a driver's seat 5 is provided.
A grain tank 9 is provided at the rear thereof, an engine 7 is arranged in an engine room 6 below the driver's seat 5, and an engine 7 is installed in front of the threshing device, which also serves as a reaping device 8a and a handling depth adjustment device. Grain culm conveying device 8b
A pre-processing device 8 consisting of the following is mounted so as to be tiltable up and down centering on the rear upper part.

The engine cover 10 forming the engine room 6 is a rear plate 10a installed upright on the machine base 2.
, the upper surface portion 11a, the front surface portion 11b, and the side surface portion 11.
The opening/closing part 11 consists of c.
is adapted to be opened and rotated outward about a fulcrum shaft 12 at the outer lower part.

Further, the front part 11b has two parts separated by a narrow space.
The driver's seat
The front part of the front part is pivotally supported on the upper part of the front part 11b so that it can be raised and lowered by a horizontal axis, and the rear part is placed on the upper part 11a.

A rear surface portion 1 in which the rear surface plate 10a extends upwardly.
0a and a top plate 10c whose upper part is bent forward.
, a bottom plate 13 that is detachably supported by a receiving crosspiece 14 and pins 15, 15, and a bottom plate that is supported by pins 15, 15 at the bottom.
The upper part is attached to the top plate 10b by the mounting bolts 16.
A mesh lid 17 screwed onto the front part of the
An air cleaner 21 is housed in a space surrounded by a removable partition plate 20 and a removable partition plate 20.
A control valve 19 for raising and lowering a discharge pipe 9a for discharging grains in the grain tank 9 is housed in the space on the side of the threshing device, and the control valve 19 tilts the operating lever 23 back and forth. The push button switch 22 attached to the operating lever 23 switches on and off the control switch of the motor that horizontally turns the discharge pipe 9a left and right.However, if the turning operation is also performed by a hydraulic cylinder, the switching valve is also in the space mentioned above. In the case shown in the figure, when the push button switch 22 is pressed and tilted, the discharge tube 9a can be rotated while moving up and down, and when both are switching valves, the operation lever By tilting 23 in an oblique direction, the discharge tube 9a can be tilted vertically and rotated horizontally at the same time.

In addition, a lever panel 30 is provided on the threshing device side of the driving section, extending from the front main shift lever 25 and auxiliary shift lever 26 to the rear threshing clutch lever 27 and reaping clutch lever 28, and further on the preprocessing device 8 side. is provided with a lever panel 32 such as a pre-processing gear shift lever 31 and a cutting height setting dial 31a, and a pulley 36 of a horizontal shaft 35 protruding from a horizontal holding cylinder 33 which serves as a tilting fulcrum for the pre-processing device 8, and a transmission case. The belt 39 which is hung over the output pulley 38 of 37 is
When removing the lever panel 32 from the machine body, the lever panel 32 can be removed from the operating step 4 by removing the screw with the knob at the front and opening the lever panel 32 around the hinge 32a at the rear.

In the combine harvester described above, the engine 7 is cooled by taking in air from the radiator 40 side by a fan on the side, and exhaust gas is discharged to the threshing device side, the front side, etc.

During work, the engine cover 10 is heated by the heat generated by the engine 7 itself, the heat of exhaust air, etc., but the front part 11b has a double structure and has a great heat insulation effect, and the lower part of the front part 11b is heated from the rear. Since it is bent toward the front and is spaced apart from the driver's feet, the driver will not get too hot even if he or she drives in a comfortable position with the heel of the foot pulled back while seated.

In addition, although the front and rear width of the driving step 4 is made as narrow as possible within the range that can be operated, the front part 11b corresponding to the heel is set back, so it is difficult to move the heel backward as described above. Sufficient operating space can be secured in which the user can take a comfortable pulled position or put his/her foot forward and depress the clutch pedal 42.

(G) Effect of the invention As mentioned above, the present invention has a threshing device mounted on one side of the machine base 2, an operation panel 3 and an operation step 4 on the front part of the other side.
A combine harvester is provided with a driving operation section consisting of a driver's seat 5 and a driver's seat 5, and an engine 7 is disposed below the driver's seat 5, in which a front part 11b of an engine cover 10 that covers the engine 7 is separated by two plates separated by a narrow interval. Since the engine cover 1 is made into a double structure and the lower side of the front part 11b is bent rearward, the engine cover 1
The heat insulating effect of the front part 11b of the 0 can prevent the driving space in front of it from becoming excessively hot, and moreover, the driver can drive in a comfortable posture with his heels close to the front of the lower part of the front part 11b. The front part 1 of the engine 7 and the engine cover 10 can be
By minimizing the distance between the driver and the driver 1b, a sufficient front-to-back width of the driving space can be ensured, which eliminates the need to remain in a cramped position for a long time, and reduces fatigue.
