Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for storing grains that have been threshed and sorted in a threshing unit in a grain tank and take out grains in the grain tank to the outside.

[0002]

Conventionally, when taking out grains from a grain tank, a discharge auger at a storage position supported by an auger rest of the machine is automatically moved to a grain discharge position such as a truck bed. While turning to perform the discharge work,
In the case of two-person work after the end of the discharging operation, there is an inconvenience such as performing a storing operation of the discharging auger by giving a signal of the end to another worker in the combine driver's seat. There was an inconvenience that the signal was hard to reach and the work was unreliable. In addition, in the case of a single-person operation, the operation of returning to the combine operator's seat and storing the discharge auger each time after the discharge operation is completed is cumbersome and extremely inefficient. Further, even when an abnormality occurs in the discharge auger or the combine body during the grain discharging operation, it is necessary to return to the body side and stop the driving of the engine each time.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a combine having a grain discharge auger for taking out grains in a grain tank, which is rotatably provided above the grain tank, wherein a remote control box is provided at the grain discharge port at the tip of the discharge auger. Mounting,
The operation box is provided with a single manual operation lever for raising and lowering the discharge auger and turning left and right, and an auger on / off switch for turning on and off the discharge auger, and automatically moving the discharge auger from the grain discharge position to the storage position. An automatic return switch is provided in the remote control box to return the manual operation, and in addition to manually turning on and off the drive of the discharge conveyor, as well as performing each operation of raising and lowering and turning at the discharge work position such as the truck bed,
At the end of the grain discharge operation, ensure that there is no need to send a signal to the other operator in the combine driver's seat in the case of two people's work, and it is not necessary to return to the combine's driver's seat each time in the case of one person's work. This makes it possible to store the discharged combine efficiently and efficiently, thereby shortening the time required for discharging the grain and improving the workability of discharging the grain.

In addition, an engine emergency stop switch for urgently stopping the engine is provided in a remote control box,
Even in the event of an abnormality occurring in the discharge conveyor or combine machine and it is necessary to stop the engine urgently, the engine operation can be stopped instantaneously without delay at the discharge work position such as the truck bed, thereby improving work stability. It is to improve.
