Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine operating device, which is used in a riding combine.

[0002]

2. Description of the Related Art An operating device in a conventional combine is
For example, as shown in Japanese Utility Model Laid-Open No. 57-28618, various operating levers are concentrated around the cockpit, but the running clutch lever for changing the traveling direction of the chassis is Usually, it is composed of a pair of left and right, and the pair of strike clutch levers are provided at the front center position of the cockpit.

Further, as shown in Japanese Utility Model Laid-Open No. 58-50626, there is also a structure in which an operating lever for operating a side clutch is provided on a lateral side of a steering device in a state of being projected outward. However, the structure is complicated, and the operation lever that projects laterally projects outward beyond the width of the vehicle, which is an inconvenience because it impedes running.

[0004]

The combine has a large number of operating points and naturally a large number of levers, and is concentratedly arranged around the cockpit. However, the problem is that the structure is simple and the operation is simple. There is a demand for simplification and simplification. Especially recently
With regard to combine harvesters, the maneuvering of old men and women has increased, and there is a demand for a structure that can be easily operated and does not cause operational errors.

In particular, in the case of a small combine, the operator runs to operate while sitting on the operator's seat, to check the right side of the chassis and to check the operating state of the attachment mounted on the rear side. There is a case where the worker performs confirmation work while walking in the field. During such work, the operator needs to be able to operate the strike clutch lever of the front control console while walking in the field.

[0006]

The present invention takes the following technical means in order to solve the above problems. That is, in a combine in which the threshing device 1 and the reaping device 2 are provided on the chassis 3, the front control platform 4 and the left control platform 5 are arranged at the front part of the chassis 3 in the forward direction, and the rear control seat is provided. 6 is provided to form a steering space 7 open only on the right side so that the driver can get on and off from the right side, and a front clutch 4 of the steering space 7 is provided with a single traveling clutch lever for converting the traveling direction of the chassis 3. -8 is a combine operation device which is provided by -8 being positioned on the right side.

[0007]

EXAMPLE First, the structure will be described. Chassis 3
A crower 9 is provided, a mowing device 2 is provided in the front part, and a threshing device 1 is mounted on the upper part so that the mowing and threshing work can be performed. The attachment device 10 is composed of a cutter and a knotter and is selectively switched so that one of them can be used, and the attachment device 10 is attached to the straw portion of the threshing device 1 to cut the straw after threshing. It has a structure that can be bound.

Reference numeral 11 indicates an engine room. The operating space 7 in which the operator rides is a driver's seat 6 provided on the front side of the engine room 11 in the traveling direction of the chassis 3, and a front side provided on the front side facing the operator's seat 6. The control console 4 and the left control console 5 provided on the left side surround the three sides and open only the right side so that passengers can get on and off from there.

The running clutch lever 8 is provided near the right side of the front control stand 4 so that it can be easily operated by the right hand while sitting on the control seat 6, and when it is connected to the running clutch mechanism of the chassis 3 and operated in the left and right directions. The traveling direction of the chassis 3 can be converted to the left-right direction. And the strike clutch lever-8 is
It is operably connected to a hydraulic mechanism, and when it is operated in the front-back direction, the harvesting device 2 can be moved up and down.

The shift lever 12 and the sub shift lever 13 have two guide grooves 14 and 15 formed in the front portion of the left-hand side control console 5, and they are inserted into each other so that they can be moved in the front-rear direction. Reference numeral 16 indicates a throttle lever. As is known in the art, the shift lever 12 shifts the traveling speed via a hydraulic transmission, and the sub shift lever 13 shifts the traveling speed.
It has a structure that allows the running speed to be switched between high and low.

The threshing clutch lever 17 and the reaping clutch lever 18 are operably inserted by providing two clutch guide grooves 19 and 20 along the front-rear direction at the rear part of the left control platform 5. The threshing clutch lever 17 is configured to transmit or interrupt the rotational power of an engine (not shown) installed in the engine room 11 to the threshing device 1. The reaping clutch lever 18 is configured to be capable of transmitting rotational power of the engine to the reaping device 2 and interrupting or operating the reaping device 2.

Reference numeral 21 is a work switching lever, which has a structure capable of selectively switching between the cutter and the knotter in the attachment device 10 described above. Reference numeral 22 is a lever for adjusting the number of rotations of the sardine lees of the threshing device 1. Next, the operation will be described. First, the engine is started, the cutting clutch lever-18 and the threshing clutch lever-17 are turned on, and the switching lever-21 is operated to operate the attachment device 10.
Switch to using a cutter and prepare.

Next, the auxiliary shift lever 13 is set to the low speed side (working speed), and the shift lever 12 is operated to start the cutting and threshing work while moving the chassis 3 forward. Then, after the grain culm in the field is mowed by the mowing device 2 in the front part,
It is supplied to the threshing device 1 to be threshed. In this way, the grain culms are successively and continuously threshed, but the grains are collected accordingly, and the straw is supplied from the terminal end of the threshing device 1 to the cutter which is the attachment device 10 and cut. .

Now, during such cutting and threshing work, the operator must run the carriage 3 along the grain culm row of the field to eliminate the generation of uncut residue. To change the direction of the chassis 3, the running clutch lever-8
Can be turned to the left when it is tilted to the left, and to the right when tilted to the right to move along the grain culm row.
This operation can be performed with the right hand, which is the normal hand of the person.

In this operation, since the running clutch lever 8 is of a single type and is located on the right side of the front control console 4, the operation by the right hand which is the dominant arm is extremely easy to perform. Then, in order to confirm the working state and the safety that cannot be confirmed while sitting in the cockpit, the operator can check the state of the right side of the chassis 3 and the attachment device 1 at the rear.
It is necessary to see the operating state of 0, but at that time, it descends from the control space 7 to the field. Even in this case, the operator can walk the side of the chassis 3 to move forward while checking, and if necessary, reach out of the field to operate the traveling clutch 8 while looking forward. Therefore, the chassis 3 is capable of continuing the cutting and threshing work while moving forward even if the operator gets down to the field, and can cut according to the grain culm row.

[0016]

As described above, according to the present invention, in a combine in which a threshing device and a mowing device are provided on a chassis, a front control platform and a left control platform are provided at a front portion of the chassis in a forward direction. Is placed and a pilot seat is provided on the rear side to form a pilot space that is open only on the right side so that you can get on and off from the right side.
Since a single steering clutch lever for changing the traveling direction of the chassis is provided on the front side control console of the control space at the right side, the steering operation of the combine is less likely to occur. However, it has a feature that it can be easily performed.

When the present invention is applied to a small combine, the operator has the convenience of being able to operate the strike clutch lever while walking in the field.
