BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device for operating a dumping auger for taking out harvested grains stored in a combine grain tank outside the machine to a storage position, a dumping position, or the like.

[0002]

In the form in which the dumping position is determined by the extendable dumping auger, the dumping auger becomes long, so that the dumping port at the distal end is far away from the machine body, and the operation of the dumping is performed. Difficult to do. For this reason, by providing an operating tool for determining the threshing position of this auger auger in the telescopic threshing cylinder 6 which expands and contracts together with the threshing port, the operator or the operator can move from the position near the threshing port. It is intended to perform an accurate positioning operation of the dumping auger.

[0003]

[0004]

The grain discharge auger 4 discharges the grains contained in the Glen tank 3 and discharges the grains from the grain discharge port 1 at the end of the telescopic waste cylinder 6 to the outside of the machine. Further, the telescopic waste tube 6 can be telescopically moved in the vertical B direction and the turning C direction with respect to the body 2. These expansion / contraction A drive, up / down B drive, turning C drive, and the like can be performed by operating the operation tool 5 provided on the expansion / contraction bin 6 having the discharge opening 1.

[0005] For this reason, even if the operator is not at a certain operation position of the machine body 2, the operator is located near the grain discharging port 1 distant from the machine body 2, 1 can be accurately and easily performed. In addition, even if the telescopic waste tube 6 is moved, the operating tool 5 has a constant position relative to the discharge port 1, so that the operational feeling does not change.
