Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for continuously cutting and threshing grain culms and taking out grains from a threshing unit to a grain tank. 2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 55-147152 or Japanese Utility Model Laid-Open No. 64-32039,
There is a technology in which a clutch lever for driving and stopping the discharge auger is attached to a discharge auger tip exit portion, and the auger clutch can be turned on and off also on the discharge auger tip side. Further, as disclosed in Japanese Utility Model Application Laid-Open No. 61-743385, an operation lever for performing operations of elevating and lowering and turning the discharge auger is also mounted on the distal end side of the discharge auger. is there. In the prior art, since the operations of driving and stopping the discharge auger, as well as raising and lowering and turning the discharge auger can also be performed on the tip side of the discharge auger, the grains of the grain tank are loaded on a truck bed or the like. The unloading operation can be performed by one operator, but the operation of the discharge auger can be performed in parallel on both the driver's seat side and the discharge auger tip side. When the operator on the driver's seat performs the lifting / lowering or turning operation of the discharge auger in the case of being on the bed respectively, there is a problem that the tip of the discharge auger collides with the worker on the truck bed. Therefore, as shown in Japanese Patent Application Laid-Open No. Hei 3-130011, a manually operated priority switch for inhibiting the operation on the driver's seat side is attached to the tip of the discharge auger, and the operation on the driver's seat side is inhibited by operating the switch. There is also a technology that operates only on the tip of the discharge auger to prevent erroneous operation on the driver's seat side.However, when the grain discharge operation is completed, the operator forgets to turn off the priority switch and the worker gets off the truck bed etc. When the worker moves away to the driver's seat side, the operation of the discharge auger on the driver's seat side is prohibited, and the operator cannot operate the discharge auger on the driver's seat side. The operator must return to the tip of the discharge auger and turn off the priority switch, and the operator must return to the driver's seat to operate the discharge auger again, simplifying the handling operation and improving the grain discharge workability. There is a problem such as that can not strive to such as on easily. [0005] Means for Solving the Problems] However, the present invention is discharged
