    Abstract: PURPOSE:To maintain the thickness of the layer of a treated product on average in a roper range to enhance the precision of a grain grading operation, by keeping a correction computation treatment at the maximum value of the thickness of the treated product, even the thickness of the layer of the treated product on a vibration-grading plate is changed from an increasing direction to the decreasing direction. CONSTITUTION:The target value of the treating capacity of a grain-grading device is set in response to the volume of grain straws fed into a threshing chamber A and subsequently corrected in response to the thickness of the layer of the treated product on a vibration-grading plate 19. The treating capacity of the grain-grading device is controlled on the basis of the corrected target value. Even when the thickness of the layer of the treated product is changed from the increasing direction to the decreasing direction, a correction computation treatment at the maximum value is maintained, until the value is lowered below the minimum set value.

    Abstract: PURPOSE:To justify the throughput of a grader and prevent clogging by setting a target value of the throughput capacity of the grader based on the grain and culm supply to a threshing chamber and correcting the target value corresponding to the thickness of layers of crops to be treated on a vibration-grading plate. CONSTITUTION:A target value of the throughput capacity of a grader is set based on the grain and culm supply to a threshing chamber (A). Corresponding to the thickness of layers of crops to be treated on a vibration-grading plate 19 of the grader, the target value is corrected and the throughput capacity of the grader is controlled.

    Abstract: PURPOSE:To reduce an error in thickness of materials for treatment discriminated based on signals from sensors by providing a correcting means for correcting the thickness of the materials for the treatment sensed by sensors according to rocking of a batten platy member. CONSTITUTION:A sensed value of a sensor (S) for sensing the thickness of materials for treatment and a sensed value of a sensor (Sb) for sensing the rocking angle of a batten platy member are read by a controller 21 and the sensed value of the sensor (S) for sensing the thickness of the materials for the treatment is corrected to determine the thickness of the materials for the treatment. If the thickness is small, a car speed is increased through a speed change actuator 23. If the thickness is great, the car speed is reduced.

    Abstract: PURPOSE:To enable reduction of residual threshing or ear overflow in a thresher to less than that in conventional combines by enabling rapid practice of regulation of threshing depth even if a reaping and treating part is rapidly lifted or lowered. CONSTITUTION:A reaping and treating part for reaping planted grain culms and conveying the reaped grain culms to a thresher is liftably and loweringly provided relatively to a main machine provided with the thresher. A threshing depth regulating means (C) is operated with a controlling means (H) so as to keep the threshing depth at the set threshing depth based on information from threshing depth sensing means (S1) and (S2) when the sensing means (S1) and (S2) sense that the threshing depth is not continuously kept at the set depth for the set time or more for delaying controlling operation. A lifting or lowering state sensing means (PM) for sensing a rapid lifting or lowering state in which the extent of lifting or lowering within the set time in the reaping and treating part is above the set value is provided. Furthermore, the controller (H) reduces the set time for delaying the controlling operation following the sensing of the above-mentioned rapid lifting or lowering state based on the sensed information from the means (PM). As a result, proper response can be made even to quick lifting or lowering of the reaping and treating part to reduce residual threshing.

    Abstract: PROBLEM TO BE SOLVED: To provide a combine harvester capable of carrying out control to move an unloader apparatus to a set position by automatic control without inconvenience, by setting a grain discharging position so as to move the position to a preset position by operating a movement actuator only for a set time in the operation of a movement switch. SOLUTION: This combine harvester is equipped with an unloader apparatus for sending grain stored in a grain tank, a movement actuator for moving a grain discharging position by changing the position of the unloader apparatus and a control device 44 for moving the grain discharging position from the apparatus to a preset position by controlling the actuator by the operation of the movement switch. The control action of the control device 44 is set so as to move the grain discharging position to a preset position by operation the movement actuator only for a set time when the movement switch is operated.
