PROBLEM TO BE SOLVED: To provide a threshing apparatus by which the treating ability of a waste dust-treating chamber is improved and the maintenance of a waste dust-treating teeth can be carried out easily.SOLUTION: The threshing apparatus is provided with the many rod-shaped waste dust-treating teeth (71a) so as to be protruded from the outer periphery of a waste dust-treating cylinder (71) pivotally supported by the waste dust-treating chamber (80), and a plate-shaped sending guide (81) in the inside of a waste dust-treating cylinder frame (72) surrounding the waste dust-treating cylinder (71), and the waste dust-sending guide (81) is tilted to the site of the waste dust-treating cylinder (71) at the downstream side in the rotation direction so as to be positioned at the rear side based on the site of the waste dust-treating cylinder (71) at the upstream side in the rotation direction. A supporting plate for attaching the waste dust-treating teeth (71a) to the outer periphery of the waste dust-treating cylinder (71) is divided to a front-side supporting plate (71b) installed in the outer periphery at the front part of the waste dust-treating cylinder (71) and a rear-side supporting plate (71d) installed in the outer periphery at the rear part of the waste dust-treating cylinder (71), and the front-side supporting plate (71b) and the rear-side supporting plate (71d) are constituted so as to be freely detachable from the waste dust-treating cylinder (71).COPYRIGHT: (C)2013,JPO&INPIT【課題】排塵処理室の処理能力を向上し、排塵処理歯のメンテナンスを容易に行うことができる脱穀装置を提供する。【解決手段】排塵処理室(80)に軸支した排塵処理胴(71)の外周面に多数の棒状の排塵処理歯(71a)を突出させて設け、該排塵処理銅(71)の周囲を覆う排塵処理胴枠(72)の内側に板状の送りガイド(81)を設け、該送りガイド(81)を排塵処理胴(71)の回転方向上手側の部位に対して排塵処理胴(71)の回転方向下手側の部位が後方に位置するように傾斜させて配置する。また、排塵処理歯(71a)を排塵処理胴(71)の外周面に取り付けるための支持プレートを排塵処理胴(71)の前部外周に備える前側支持プレート(71b)と排塵処理胴(71)の後部外周に備える後側支持プレート(71d)とに分割し、該前側支持プレート(71b)及び後側支持プレート(71d)を排塵処理胴(71)に対して着脱自在な構成とする。【選択図】図5
