DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general-purpose combine, and more particularly, to an operation unit structure for operating a cutting unit of the combine.

[0002]

2. Description of the Related Art Conventionally, in a general-purpose combiner of this type, a squeeze reel connected to the front of the fuselage is configured to be able to move up and down and to be adjustable in the front-rear position. That can be included.

[0003] The operation of the scraping reel is performed through operating means provided in the control unit.

[0004] For example, in a general-purpose combiner in which a steering wheel for steering is disposed immediately in front of a driver's seat, a main shift lever for traveling is provided on the left rear side of the steering wheel, that is, on the left side of the front end of the driver's seat. A switch for raising and lowering the entire reaping unit and a switch for adjusting the vertical position of the scraping reel are provided on the grip of the lever, and a cross lever type operation lever is disposed on the right side of the steering wheel. Operation to the left and right, or
In the case of a column type in which the operation lever protrudes to the side of the steering wheel, there has been a device in which the front-rear position adjustment and the rotation speed adjustment of the squeezing reel are performed in accordance with the operation up, down, front and back.

[0005]

However, the above-mentioned structure has a problem that has not been solved in operability.

That is, the vertical position of the scraping reel is adjusted by a switch on a main shift lever disposed on the left side of the steering wheel, and the front-rear position and rotation are adjusted by a cross lever type operation disposed on the right side of the steering wheel. The operation is not easy because the adjusting means of the scraping reel is separated to the left and right, such as by using a lever. In other words, it is necessary to hold the steering handle between the left and right hands while traveling, and it is difficult to quickly and accurately adjust the front and rear positions and the vertical position of the scraping reel even in a normal reaping operation. Even the efficiency was reduced. When it is performing high-speed mowing or the like, it is almost impossible to adjust the front-rear position or the rotation by the above-mentioned cross lever type operation.

An object of the present invention is to provide a general-purpose combine which can solve the above-mentioned problems.

[0008]

According to the first aspect of the present invention, a mowing unit is provided in front of a fuselage equipped with a traveling device, and a steering handle for steering the traveling device and traveling are provided above the fuselage.

A cutting section automatic control switch, a vertical position adjustment switch of a scraping reel provided in the cutting section, a front / rear position adjustment switch of the same, and a rotation speed adjustment switch of the same. .

Further, according to the present invention, a grip is provided at the upper end of the traveling main speed change lever, and the grip has a front side facing the fuselage advancing side and one side facing the driver's seat side. A switch arrangement part was formed, and switches were distributed in each arrangement part.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a mowing part is provided in front of a fuselage equipped with a traveling device, and a steering handle for operating the traveling device and a main shifting lever for traveling are provided above the fuselage. In a general-purpose combine provided with a control unit and a threshing unit for threshing the grain stalks harvested and fed by the reaping unit, a plurality of operation switches related to the reaping unit are centrally arranged on the main shift lever for traveling. .

That is, even when the steering wheel is held with one hand (usually the right hand) and the main shift lever is operated with the other hand (usually the left hand), the steering wheel is disposed on the reaper. It is possible to adjust the front / rear / up / down position of the scraping reel, adjust the rotation speed of the reel, and operate the lifting / lowering operation of the entire reaping unit, thereby significantly improving operability.

A switch for adjusting the rotation speed of the scraping reel can be used, and the front-rear position and the vertical position of the scraping reel can be quickly and accurately adjusted even during traveling, so that work efficiency is improved. In addition, with such a configuration, for example, even in the case of high-speed mowing work, the front-rear position adjustment and rotation adjustment of the scraping reel can be performed.

Preferably, furthermore, a switch for raising and lowering the entire reaping unit, and a switch for automatically controlling a reaping unit for automatically controlling the raising and lowering operation so that the entire reaping unit is at a proper work start position and a proper work end position. It is also preferable that the vertical position adjustment switch of the scraping reel provided in the mowing unit is also disposed integrally on the main shift lever for traveling.

If these switches are provided, the control of the mowing section can be performed almost completely on the main shift lever, and during the operation of the main shift lever, the hand is changed one by one or reached to another place. There is no need to perform such operations, and the operability of the combine is improved.

Further, each switch described above can be laid out as follows.

That is, a grip is provided at the upper end of the traveling main shift lever so that it can be easily gripped and fits on the palm. The grip has a front side facing the fuselage advancing side and one side facing the driver's seat side. A switch arranging section is formed, and switches are arranged in each arranging section in a distributed manner.

The first switch mounting portion formed on the front side surface of the grip can be formed on the upper surface of the front projecting portion formed in the middle of the grip main body. Two switch levers can be protruded obliquely upward. Each lever can be assigned to, for example, the entire reaping unit and the raising / lowering operation of the scraping reel.

On the other hand, the second switch mounting portion formed on one side surface of the grip is desirably formed in a range operable with the left thumb, and the second switch mounting portion includes, for example, a reaper. A unit automatic control switch, a front / rear position adjustment switch of the scraping reel, and a rotation speed adjustment switch of the scraping reel can be provided. Each of these switches is operated by pushing in the forward and backward directions, thereby enabling an operation command to the +/- side in accordance with the pushing operation time and pushing amount, and automatically neutralizing after the operation is completed. It is desirable to use a seesaw type switch that returns.

It can be added to a switch for raising and lowering the scraping reel provided in the section.

For example, the switch for raising and lowering the scraping reel can be operated in the cross direction, and the switch can be pulled up. When the switch is operated in the front-rear direction in a normal state, the height position of the reel is adjusted. In this case, the rotation speed can be adjusted, and when the switch is pulled up and operated back and forth, it is possible to adjust the front-rear position of the reel.

Further, as another embodiment, for example, when the reaping section automatic control switch is operated at the time of starting the reaping, the reaping section is set to an appropriate position (the scraping reel moves up,
The cut switch can be divided into a set switch that moves down as a mowing unit) and a switch that operates when the mowing is completed so that the mowing unit takes an appropriate position accordingly (the raking reel moves down and rises as a mowing unit). it can. In this case, if the switch is a push button type, the operation can be performed easily.

As described above, according to the present invention, the operation of the mowing unit, in particular, the front-rear adjustment and the rotation speed adjustment of the scraping reel can be performed without releasing the hand from the main shift lever.
Work efficiency can be improved.

In addition, since the switches are arranged ergonomically in accordance with natural finger movements, operability is good and there is no possibility of erroneous operation.

Also, by arranging the switches, which were conventionally arranged elsewhere, on the main shift lever, the switch layout is simplified, and the operation panel for arranging the switches in the control unit can be made compact. Therefore, the livability in the control section is improved, and getting on and off is also simplified.
