In the one in which unprocessed material is sent to the processing chamber from the dust outlet opening in the wastewater outlet of the handling chamber and threshing is performed by the handling chamber and the treatment chamber, a control valve is provided at the dust inlet and the straw transfer route. The straw flow rate sensor is provided in each of them, the straw flow rate sensor and the control valve are connected, and the degree of opening of the dust-sending port is automatically widened or narrowed by the control valve according to the detection amount of the straw flow rate sensor. It was constructed so that it could accomplish the purpose described in the previous section.

[0005]

With the above construction, the grain culm supplied into the handling chamber is threshed, and the untreated matter is delivered from the dust outlet of the culm to the treatment chamber where it is treated. Then, the threshed straw is discharged through the straw conveying path, and the threshing processed by the handling chamber and the processing chamber is sorted by the rocking sorter or the like. Straw flow sensor
Detects the layer thickness of straw and operates the control valve installed in the dust inlet depending on the thickness to adjust the opening degree to adjust the amount of unprocessed material discharged from the dust inlet to adjust the amount of unprocessed material. The threshing treatment share is balanced.
