PROBLEM TO BE SOLVED: To provide a thresher which attains high-efficiency threshing work by reducing a jam of processed product in a threshing chamber.SOLUTION: In a thresher, a cylindrical body (61) includes: a take-in spiral part (16) and a cylinder part (17) where a plurality of threshing teeth (18A, 19A) are erected. A front end part of the inner peripheral surface of a threshing chamber cover (40) covering the upside of a threshing cylinder (11) is provided with a fixed guide (48) disposed with such a gradient that a part on the downstream side in the rotating direction of the threshing cylinder (11) is located in the rear of a threshing chamber (10). At the back of the fixed guide (48), a plurality of movable guides 42 are provided to be variable in the inclination attitude to the rotating direction of the threshing cylinder (11). A rear end part (48B) of the fixed guide 48 extends to the back part from the take-in spiral part (16) in the cylindrical body (61).COPYRIGHT: (C)2014,JPO&INPIT【課題】扱室内の処理物の詰まりを少なくして脱穀作業の能率の高い脱穀装置を提供する。【解決手段】上記課題は、筒体(61)を取込み螺旋部(16)と複数の扱歯(18A,19A)を立設した筒部(17)を備えて構成し、扱胴(11)の上部を覆う扱室カバー(40)の内周面の前端部に扱胴(11)の回転方向下手側の部位ほど扱室(10)の後方に位置するように傾斜して配置された固定ガイド(48)を設け、固定ガイド(48)の後側には、扱胴(11)の回転方向に対する傾斜姿勢を変更可能に構成された複数の可動ガイド(42)を設け、固定ガイド(48)の後端部(48B)を筒体(61)における取込み螺旋部(16)よりも後側の部位まで延設することにより解決される。【選択図】図4
