Description

TECHNICAL FIELD The present invention relates to an operating device in a combine,
Used for small combine harvesters.

[Prior art]

A conventional operating device of this type of combine is, for example, as disclosed in Japanese Utility Model Laid-Open No. 57-28618, steering clutch levers consist of a pair of left and right, and the center of the operation panel located in front of the control seat. It is a normal configuration to be provided at a position.

Moreover, the lever for raising and lowering the mowing device has a structure different from that of the steering clutch lever, and a complicated operation is required for the traveling mowing work.

[Problems to be Solved by the Invention]

This kind of combine has many operation points during work,
The operator has been required to perform complicated operations.

For this reason, the operator is nervous because he is nervous to prevent erroneous operation, which causes great fatigue. In addition, the combine becomes extremely complicated in terms of configuration,
The cost was high.

[Means for Solving the Problems]

The present invention takes the following technical means in order to solve the problems described above. That is, a machine 4 provided with a traveling device 3 is equipped with a reaping device 1 for cutting grain culms, a threshing device 2 for threshing grain culms cut by the reaping device 1, and the like,
At the front part of the machine stand 4, there is provided a cockpit 5 that can be got on and off from the right side in the forward direction, and cockpits 6, 8 are arranged at the front side and the left lateral side of the cockpit 5, respectively. A steering clutch lever 7 consisting of a single lever that can raise / lower the reaping device 1 by front / rear operation and can steer the forward direction of the vehicle body by left / right operation is provided near the right hand side of the control platform 6 of the other 8 The operating lever is not arranged, and the gearshift lever 9 of the traveling device 3 is provided at the front position on the left-hand side control platform 8, and at the rear position, the motive power to the reaping device 1 can be intermittently operated. 1 is a combine operating device provided with a threshing clutch lever 11 capable of intermittently operating power to the lever 10 and the threshing device 2.

[Action / effect]

According to the present invention, when the steering clutch lever 7 is operated in the forward direction, the harvesting device 1 is lowered,
When operated backward, the reaping device 1 goes up. In addition, the steering clutch lever 7 can be operated in the left-right direction to operate the traveling direction of the vehicle body to safely perform the mowing and threshing work.

By operating the speed change lever 9, the traveling device 3 can be moved forward / backward and the traveling speed can be changed. By operating the reaping clutch lever 10, the transmission to the reaping device 1 can be interrupted, and by operating the threshing clutch lever 11, the transmission to the threshing device 2 can be intermittently operated.

The positions of these operating levers are determined according to the frequency of use during work. Especially, since the steering clutch lever 7 is used most complicatedly, the front side of the cockpit 5 is easily approached by the right hand. It is located at a position close to the rightmost row of stalks, and is isolated from other operating levers.

The other operation levers are also positioned according to the frequency of use, and the speed change lever 9, the reaping clutch lever 10 and the threshing clutch lever 11 are attached to the operation console 8 on the left side of the cockpit 5.
In addition, it is arranged in the order of frequency of use from the front side to pursue ease of operation and to prevent mistakes in operation.

In addition, according to the present invention, there is a cockpit that can get on and off from the right side in the forward direction, and a steering clutch lever is provided in a state of being isolated from other levers near the right hand side (boarding side) of the front control stand. With this configuration, when operating while sitting in the cockpit 5, it is easy to reach with the right hand side of the control stand 6 on the front side of the cockpit 5, and pay attention to the rightmost row of the harvested culm. However, it is easy to maneuver the joints while enabling the following special work operations quickly and smoothly.

That is, the operator leans forward and leans to the outside of the right side of the machine base during mowing and threshing work, or reaches the field and walks while checking the right rear and the lower side of the machine while reaching out from the field. The steering clutch lever on the right side can be operated easily and quickly without fail.

Especially, whether the attachment device (cutter, knotter) attached to the rear part of the threshing device is operating normally,
It is difficult to confirm directly from the cockpit 5, and the operator
You may lean out to the side from the combine while you are running, or you may get off and check it, but at that time, you can quickly and easily operate the steering clutch lever 7 without messing even while walking in the field, It has a unique effect that the direction of can be corrected freely.

〔Example〕

In the illustrated example, above the machine base 4, from the front side to the rear side, a mowing device 1, a threshing device 2 and an attachment device 12 such as a cutter / knotter are sequentially arranged, and a traveling device 3 is provided below. There is. On the front side of the threshing device 2,
A prime mover room 13 is provided, and a cockpit 5 is arranged in front of the prime mover room 13.

Then, the control stand 6 is arranged on the front side of the control seat 5, and the control base 8 is provided on the left side of the control seat 5 on the threshing device 2 side.

When the steering clutch lever 7 is operated in the left / right direction, it interlocks with the steering clutch mechanism to convert the traveling direction of the vehicle body to the left / right direction, and when operated in the front / rear direction, it interlocks with the hydraulic mechanism to raise / lower the harvesting device 1. In this way, the front operation platform 6 is provided on the right side in the traveling direction in a state of being isolated from other operation levers.

Therefore, the steering clutch lever 7 is arranged so that it can be operated by the right hand of the dominant arm while sitting on the cockpit 5.

Further, front and rear shift guide grooves 14 and 15 are provided side by side at the front part of the left side control platform 8, and a shift lever 9 is provided in the outer guide groove 14 and a shift lever 9 is provided in the inner guide groove 15. Is the auxiliary shift lever
16 are provided so that they can be inserted through each and swingable in the front-back direction.

A throttle lever 17 is provided on the side of the guide groove 15 so as to be rotatable in the front-rear direction. The speed change lever 9 is configured to interlock with the traveling device 3 via a hydraulic speed change mechanism, and the auxiliary speed change lever 16 is configured to switch the traveling speed between high and low.

Further, clutch guide grooves 18 and 19 along the front-rear direction are juxtaposed at the rear part of the control base 8, the outer guide groove 18 is provided with a threshing clutch lever 11, and the inner guide groove 19 is provided with a cutting clutch. A lever (10) is provided so that it can be inserted into each of the levers and turned in the front-rear direction. Threshing clutch lever 11 is in the cockpit 5
The power transmission to the threshing device 2 is intermittently performed from a prime mover (not shown) disposed below the cutting machine 1, and the mowing clutch lever 10 is configured to intermittently power transmission to the mowing device 1.

Further, the work switching lever 20 for the cutter and the notter, which is the attachment device 12, is located behind the threshing device 2.
Is provided. Moreover, you may provide each part adjustment lever, such as the Karatsu rotation number adjustment lever 21 of the threshing apparatus 2.

The reaping clutch lever 10 and the threshing clutch lever 11 are operated by turning on and off to transmit to the reaping device 1 and the threshing device 2, and the switching lever 20 of the attachment device 12 is operated as necessary. Then, the speed change lever 9 is operated to cause the traveling device 3 to travel, and the steering clutch lever 7 corrects the traveling direction to the left or right, and the work is performed while moving up and down the mowing device 1.
