Description

[Detailed description of the invention] Industrial applications The present invention relates to a combine harvester operating device.

Conventional technology Conventionally, a combine harvester was equipped with a grain tank to discharge the grain.
The invention solves the problem in that the lever that operates the elevation of the reaping device and the lever that rotates the direction of the discharge auger are each separately arranged. When the grains stored in the grain tank are to be discharged by the discharge auger, the machine must be stopped at a predetermined position, the power transmission to the traveling device is turned off, and the discharge auger is rotated in the direction using the operating lever. However, in order to align the ejecting position, the machine may be moved by turning on/off the running clutch while transmitting power to the traveling device to align the ejecting position. In some cases, it is necessary to operate the operating lever to turn on and off the running clutch and the operating lever for the discharge auger, which makes operating the levers complicated and cumbersome.Also, operating the operating lever for the discharge auger during reaping work or while driving can cause problems. This is unfavorable from a safety standpoint as the discharge auger rotates.

Therefore, in this invention, the operating lever for raising and lowering the reaping device and for engaging and disengaging the running clutch on the machine side is also used as the operating lever for rotating the discharge auger in the direction when the transmission to the running gear is cut off and the grain is discharged. The aim is to simplify the lever and improve safety.
