<p><P>PROBLEM TO BE SOLVED: To prevent reduction in sorting accuracy by increase or decrease of the amount of a material to be treated in a thresher. <P>SOLUTION: The thresher includes such a constitution that as layer thickness of a material to be treated detected by a layer thickness detection means (95) laid on a swinging sorting shelf (20) is increased, the air sending direction of sorting air from a winnower (16) is changed to the rear side of the swinging sorting shelf (20) and a discharge opening (56) is opened; and as the layer thickness of the material to be treated detected by the layer thickness detection means (95) is decreased, the air sending direction of the winnower is changed to the front side of the swinging sorting shelf (20) and the discharge opening (56) is closed. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
