Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a stock arrangement device in a combine harvester bundling device.

0002

[Conventional technology]

In the bundling device for combine harvesters, when bundling the waste straw, the stock origin of the waste straw is The stock arrangement board is used to arrange the stock, but the position of the stock arrangement device has to be changed in response to changes in the culm height of the straw. It is necessary to move the location. To move the position of the stock arrangement device, move it to the left outer side of the bundling device, that is, when the grain culm is in the erect state. Movement was performed by pushing and pulling the operating tool installed on the unharvested side.

0003

[Problem that the idea aims to solve]

The position of the stock arrangement device is moved by pushing and pulling using the conventional operating tool described above. Because the process is carried out by entering the unharvested grain culm, there is a risk of stepping on the unharvested grain culm. This has been a problem as it can result in a loss of harvest. Also, due to push and pull The moving operation has problems such as being heavy and difficult to operate.

0004

[Means to solve the problem]

The technical measures taken by the present invention to solve the above problems are self-threshing type threshing equipment. A support frame for the bundling device is provided at the rear, and a flat part is attached to the support frame in the direction of the culm of the waste straw. A stock alignment device having a stock alignment plate is slid on the guide frame. In a freely held bundling device, a culm of waste straw provided integrally with the support frame; The actuating body is wound around a plurality of wheels having appropriate intervals in the body direction, and the actuating body is attached to the stock arrangement. The moving operation tool is connected to the machine and is rotatable from the rear of the aircraft. It is interlocked and connected to one of the wheels.

[0005]

[Effect]

Based on the above configuration, the stock arrangement device that is slidably held on the guide frame is The actuator is connected to the support frame of the bundle device, which is wrapped around multiple wheels at appropriate intervals. , rotate the mobile operating tool from the rear of the aircraft to operate the wheel connected to the mobile operating tool. and slide it to the appropriate position along the guide frame according to the length of the straw culm. The stock leveling plate of the stock leveling device that has been moved to the appropriate position is used to collect waste straw transported from the self-threshing type threshing device. The stocks are tied together using a binding device and discharged outside the aircraft. In addition, the movement control tool must be gripped. Press the spring to unlock the wheel and rotate it against the spring. rotation maneuver After the operation is completed, if you remove the pushing force from the grip, the ring of the moving control tool will be released by the spring. to lock.
