That is, the valve body (59b) having the switch (62) is supported by the outer end of the case (43) of the adjusting shaft (69) integrally supporting the adjusting valve (58), and the valve body (59b) is supported. The lower surface is brought into contact with the peripheral surface of the cam member (68) of the cam operating shaft (67), and the adjustment shaft (69) is also provided.
A switch operation plate (70) having a fixed base end is contacted and supported by an actuator (62a) of the switch (62), and a sensor arm is attached to a selection amount sensor (71) provided in the selection cylinder (22). (72), flow control rod (7
3) and the adjusting shaft (69) through the arm plate (74)
The cam member (68) regulates the maximum opening degree of the control valve (58), and the regulation rod (73) regulates the minimum opening degree of the control valve (58). When a paddy load of a certain amount or more is applied, the operation plate (70) presses the actuator (62a) of the switch (62) to turn on the switch (62) and sense the normal operation. . That is, during normal operation, more than the amount of paddy that the operation plate (70) turns on the switch (62) is flowing over the control valve (58), and the sorting amount in the sorting cylinder (22) is proper. is there. In this state, when the sorting amount in the sorting tube (22) becomes large, the rod (73) moves in the direction of the solid line arrow in FIG. 9 to move the operation plate (70) upward, and the switch (62) is turned off. To detect abnormal driving.
