Description

[Detailed Description of the Invention] (a) Field of Industrial Use The present invention relates to a combine that is equipped with a threshing device and travels in farmland to mow crops and harvest kernels, and in particular, the mowing section in the traveling direction. The present invention relates to a combine that improves operability including the operation of a lateral slide mechanism that moves in a vertical direction.

(b) Conventional technology The crawler track on the uncut side of the combine may traverse the area near the plant base of the crop during mowing work. Crops of crops trampled in this way will fall. When the farmland is sufficiently hard, the fallen grain culm returns to the standing state when the contact state with the crawler belt is released. However, if the agricultural ground is soft, the grain culm may not be able to stand up, and may remain lying, making it difficult to perform the next mowing operation. Therefore, in the conventional combine, as shown in FIG. 3, a screw shaft 32 that is screwed into a screw hole portion 31 fixed to the mowing portion 23 is fixed to the rotation shaft of the motor M, and the rotation of the motor causes the mowing portion 23 to move in the arrow direction. A device having a lateral slide mechanism that moves in the A and B directions has been devised. With this configuration, the reaping unit 23 is moved in the direction of arrow A to the state shown by the chain double-dashed line in FIG. You can prevent trampling the culm. Further, by moving the reaping unit 23 to a position indicated by a chain double-dashed line in the vicinity of the traveling position of the combine 21, more grain culms can be reaped and a wide space can be formed for the traveling operation.

(c) Problems to be solved by the invention However, if a switch for operating the lateral slide mechanism is provided independently on the operation panel, the operator must remove one hand from the handle in order to operate the switch. However, there is a risk that the operator may lose balance in the operation unit and the operability of the cutting operation may deteriorate.

The purpose of this invention is to provide a switch for operating the lateral slide mechanism in consideration of the arrangement of other levers and the like that are operated during mowing work, so that the operator does not lose balance when operating the switch, and the mowing workability is improved. It is to provide a combine that can improve.

(d) Means for solving the problemsThe combine of the present invention is a directional control lever that is swingable back and forth and left and right on the right part of the operation panel, and is independently fixed to both left and right parts of the operation panel. The left side is higher than the right side,
Further, it is characterized in that a handle whose left side is at the same height as the direction control lever and a slide switch which is attached to a part of the left side lever and operates the lateral slide mechanism are provided.

(e) Operation In this invention, the direction control lever operated when the direction is manually controlled is located on the right side of the operator, and the switch for operating the lateral slide mechanism is attached to the handle located on the left side of the operator. Therefore, the operator grips the direction control lever with the right hand and the handle with the left hand during the mowing operation. The operator can maintain stability by gripping the handle with the left hand, and controls the traveling direction with the right hand. Also, a switch for operating the lateral slide mechanism can be operated with a part of the left hand holding the handle. Even during this operation, the handle and the direction control lever are continuously gripped by the left and right hands.

(f) Embodiment FIG. 2 is an external view of a combine that is an embodiment of the present invention.

The combine 21 has a threshing device 25 installed therein, and the track 2
Rotate 4 to run in farmland. At the front part of the upper surface of the combine 21, a control part 22 having the operation panel 1 is formed. Further, the harvesting section 23 is provided at the front of the combine 21.
Is installed. The mowing unit 23 guides the crop located in front of the combine 21 into the inside by the feeding claw 26 and the raising claw 27, and mows the grain culm of the crop from the plant root by a cutting blade (not shown). The harvested grain culm is introduced into the threshing device 25 by the transport device 28, and only the grain is separated and harvested. The reaper 23 is moved up and down by an elevating device (not shown) to change the cutting height of the grain culm. Further, the reaping unit 23 moves in the directions of arrows A and B by the above-mentioned lateral slide mechanism.

1 (A) and 1 (B) are a plan view and a front view showing an operation panel of the combine, respectively.

Handles 3 and 4 are fixed to the left and right of the front side of the operator on the operation panel 1 provided with the display unit 6, the instruction button 7 and the ignition key 8. The left handle 3 is formed higher than the right handle 4, and a switch 5 is provided on the upper surface thereof. When the switch 5 is operated once, the reaper 23 moves in the direction of arrow A, and when the switch 5 is operated next, it moves in the direction of arrow B. A direction control lever 2 is provided in front of the right handle 4. The direction control lever 2 is swingable back and forth and left and right, and the combine 21 moves in the direction in which it is swingably operated from the neutral position to the left and right. Further, when operated back and forth, the reaper 23 is lowered and raised. The direction control lever 2 is formed at substantially the same height as the left handle 3.

With the above configuration, the operator grips the handle 3 with the left hand and the direction control lever 2 with the right hand during the mowing operation. The operator can maintain balance in the control unit 22 by gripping the handle 3 with the left hand, and can control the direction of the combine 21 by gripping the direction control lever 2 with the right hand. When the direction is manually controlled by operating the direction control lever 2, the operator determines the traveling direction of the combine 21, so that the direction and magnitude of the force that the body receives when changing the direction can be predicted. The balance can be easily maintained by gripping only the handle 3 of. In addition, the switch 5 may be operated with a part of the left hand in order to move the reaping unit 23 by operating the lateral slide mechanism. At this time, it is not necessary to release the gripped state of the handle 3 by the left hand, and the operator can maintain balance even when operating the switch 5. At this time, since the direction control lever 2 and the handle 3 are set at the same height, the operator can hold both the left and right arms in the same state, and the operability is good. Further, when the direction control of the combine 21 is automatically performed, the operator cannot determine the traveling direction, and it is difficult to predict the magnitude and direction of the force acting on the body by changing the direction, but the operator controls the direction. Since it is not necessary to operate the lever 2, the right handle 4 can be gripped by the right hand. Therefore, at the time of automatic direction control, the operator can hold both the left and right handles 3 and 4, and the balance can be maintained in the control unit 22. Even in this case, the switch 5 can be operated without releasing the gripped state of the handles 3 and 4 with both hands.

The switch 5 for operating the lateral slide mechanism may be attached to the handle 3 so as to be swingable left and right, and the reaper 23 may be moved in the direction in which the switch 5 is operated.

(g) Effect of the Invention According to this invention, the operator can grasp the direction control lever with the right hand and the handle with the left hand during the direction control.
Since the handle held by the left hand is provided with the switch for operating the lateral slide mechanism, the operator can operate the switch while holding the handle. In this way, since the handle can always be gripped during direction control, the operator can easily maintain balance in the control section, and can easily perform work involving direction control such as mowing work. Further, since the handle has the same height as the direction control lever, the height of the left and right hands can be made constant, and the direction control lever can be easily operated.
