(Explanation of operation of bucket elevator)
As shown in FIG. 15, on the input side of the controller 80 provided in the control unit 6, there are a discharge switch 65 that detects a discharge operation by the operator, and an output terminal of an open / close sensor 62 that detects the open / close state of the shutter 50. The output terminal of the rotation sensor 63 for detecting the rotation state of the driven sprocket 51 of the bucket type elevator 8 and the output terminal of the rotation sensor 64 for detecting the rotational speed of the output shaft 61 of the bucket type elevator 8 are connected. On the output side, a bucket type elevator drive clutch 81 that transmits the rotation of the engine to the bucket type elevator 8 and an input terminal of an engine stop means 82 that stops the engine are connected. In addition, the bucket type elevator drive clutch 81 in the present embodiment connects and disconnects the transmission by changing the tension of the belt 27 by the tension adjusting motor 71 described above.

  As shown in FIG. 16, when the discharge switch 65 is ON (when the operation for driving the bucket elevator 8 is performed), it is subsequently determined whether or not the output of the open / close sensor 62 is present. On the other hand, when the output of the discharge switch 65 is OFF (when the operation to drive the bucket elevator 8 is not performed), the bucket elevator drive clutch 81 is disconnected or the engine is stopped by the engine stop means 82, and the bucket type The elevator 8 is stopped.

  When the output of the open / close sensor 62 is ON (a state where the shutter 50 is opened), the presence / absence of the output of the rotation sensor 63 is subsequently determined. On the other hand, when the output of the open / close sensor 62 is OFF (a state in which the shutter 50 is closed), the bucket elevator drive clutch 81 is maintained in the connected state, and the bucket elevator 8 is driven.

  When the output of the rotation sensor 63 is ON (the driven sprocket 51 of the bucket type elevator 8 is rotating), the output value of the rotation sensor 64 is subsequently determined. On the other hand, when the output of the rotation sensor 63 is OFF (the driven sprocket 51 of the bucket type elevator 8 is in a stopped state), the parts such as the bucket 54 are damaged inside the bucket type elevator 8 due to a grain bridge such as soybeans. In order to prevent this, the bucket type elevator drive clutch 81 is disconnected, or the engine is stopped by the engine stop means 82, and the bucket type elevator 8 is stopped.

  When the output value of the rotation sensor 64 is equal to or higher than a specified value (a state where a load equal to or lower than the specified value is applied to the drive sprocket 52 of the bucket type elevator 8), the bucket type elevator drive clutch 81 and the engine stop means 82 are maintained in the connected state. Then, the bucket type elevator 8 is driven. On the other hand, when the output value of the rotation sensor 64 is less than a specified value (a load exceeding the specified value is applied to the drive sprocket 52 of the bucket type elevator 8), the device such as the bucket 54 by a grain bridge such as soybean is used. In order to prevent breakage, the bucket type elevator drive clutch 81 is disconnected or the engine is stopped by the engine stop means 82 to stop the bucket type elevator 8.
