When the stop state of the drive motor 34 is confirmed and detected, the drive output of the drive motor 34 is stopped after a set time, and an alarm is issued by the horn 50 or the like. Thereby, the overload of the drive motor 34 due to the abnormality of the scraper 30 can be reduced, and the operator can be aware of the abnormality of the scraper 30 and can cope with it at an early stage. When the rotation sensor 49 confirms the rotation operation of the drive motor 34, the operator can confirm the operation status of the scraper 30 by turning on the pilot lamp 51 provided in the operation unit, FIG. Even if there is a problem, it can be dealt with early by turning off the pilot lamp 51.

  In the flowchart shown in FIG. 16, when the threshing clutch switch 48 is turned on in a signal ON state (engine start state) by the oil pressure sensor 47, the motor 34 is driven and rotated by the output from the controller 46. When the rotation sensor 49 detects the rotational operation state of the motor 34, the pilot lamp 51 is turned on by the output from the controller. Further, when the rotation sensor 49 detects the stop state of the motor 34, the motor drive output is stopped after a set time, and is output to the buzzer (horn 50) to alert the operator.

On the transfer shelf 16 that receives the processed material from the receiving network of the handling chamber and the second reduction port, the processed material that falls on the transfer shelf is moved from one side of the second processing cylinder 7 to the start side of the first sheave 17.

The sensor float 54 of the layer thickness sensor 55 is pivotally attached to the sensor thickness 54, and the sensor float 54 is configured to swing up and down in accordance with the amount of processing material flowing along the approach guide plate. Since the layer thickness sensor 55 is configured to detect the layer thickness of the processed material that flows along the guide plate, the detection accuracy of the processed material amount is stable and can be accurately detected.

  By using the layer thickness sensor having such a configuration, the operation (swinging) speed of the scraper 30 can be variably controlled in accordance with the amount of processed material detected by the layer thickness sensor 55. In other words, the processing speed can be optimized by increasing the operating speed of the scraper 30 when there are many processed objects and operating it slowly when there are few processed objects.

  In addition, the configuration is such that the inclination angle of the movable sheave plate 27 of the second sheave 18 is variably controlled according to the sensing of the processing amount by the layer thickness sensor 55, or the strength of the sorting wind is variably controlled according to the processing amount. You can also.

The middle wind selection path A is divided into three stages so as to consist of the path C, and the selected wind passes mainly within the range of the Glen sheave 20 and the second sheave 18, and the upper wind selection path A B is a configuration in which the sorting wind passes through the terminal side of the first sheave 17, and the lower wind selection path C is such that the sorting wind flows toward the upper Strollac 19 through the upper surface of the first return shelf 21 a. It has become.

  The wind fluid 56 provided between the middle wind selection path A and the upper wind selection path B is configured to swing up and down about the pivot point Q1 on the start end side as a rotation center, which is shown in FIG. When the rocking displacement is caused from the solid line position to the virtual line position in FIG. 3, the wind flowing through the middle wind selection path A is inclined sharply upward and reaches the end side of the first sheave 17. In addition, the wind fluid 57 provided between the middle wind selection path A and the lower wind selection path C is configured to swing up and down about the fulcrum shaft Q2 of the intermediate portion as a center of rotation. Swaying from the solid line position to the virtual line position, the wind flowing through the lower wind selection path C decreases and the wind flowing through the middle wind selection path A increases, and the wind flowing through the lower wind selection path C suddenly rises backward. It is inclined to reach the end side of the second sheave 18. According to this configuration, it is possible to change and adjust the flow direction of the wind according to the amount of processed material on the swing sorting shelf 15, and to reduce the third loss and improve the sorting accuracy.

  The wind fluids 56 and 57 may be configured to change the wind direction in accordance with the amount of detection by the layer thickness sensor 55 that detects the amount of processed material provided on the swing sorting shelf 15.
