PROBLEM TO BE SOLVED: To provide a threshing apparatus capable of receiving straw dust from a threshing chamber and threshing in a processing chamber in high performance. SOLUTION: A processing chamber holding the axis of a treating cylinder in longitudinal direction is placed at a side of a threshing chamber holding the axis of the threshing cylinder in longitudinal direction. A sorting wind channel to send air from a winnower backward is placed under the threshing chamber and the processing chamber, the sorting wind channel has a shaking sorting shelf in a manner to enable free swing in the longitudinal direction, and a cross-flow fan for discharging dust is provided at the end of the sorting wind channel. The front end of a post-treating chamber of the treating chamber is connected to the rear end of the threshing chamber through a dust-sending channel, the pretreating tooth at the front end of the post-treating cylinder rotatably supported in the post-processing chamber has a sweepback angle to retreat the downstream side of the rotation, and the post-processing tooth at the rear end of the post-processing cylinder of the post-processing chamber has a sweepback angle to retreat the downstream side of the rotation. The intermediate processing tooth of the middle part of the post-processing cylinder has a quadrilateral plate on a side view and nearly perpendicular to the rotary axis. A cutting blade is placed close to the rotating side face of the intermediate treating tooth. COPYRIGHT: (C)2006,JPO&NCIPI
