[Problems to be solved by the invention]
In the conventional technology, the raising and lowering operation and the turning operation of the discharge auger can be performed by the main unit side operation unit and the auger side operation unit, and when both the main unit side operation unit and the auger side operation unit are operated simultaneously, the auger The operation at the side operation unit is prioritized. However, when working with two people, one person operating on the auger side operation unit and the other operating on the machine side operation part, etc., the operator on the auger side works facing the machine side. Therefore, the auger moves laterally with respect to the turning direction of the auger. At this time, if there is a case where the auger-side worker is not aware of an obstacle or the like, it cannot be stopped even if the machine-side worker operates the auger. In addition, even if clogging occurs while the grain is being discharged, it cannot be stopped from the machine side. In addition, if it is operated on the auger side, it cannot be corrected on the machine side.
[0004]
In addition, in the conventional technique, when the operation is performed with the auger side operation unit, the driving is performed at a lower speed than when the operation is performed with the machine side operation unit. When operating with the machine side operation unit, even if there is a person's or obstacles near the tip of the auger due to a shift in speed, there is a case where the robot moves rapidly and becomes dangerous. In view of the above, the present invention is designed to stop driving and improve safety when both the machine side operation unit and the auger side operation unit are operated simultaneously.
[0005]
