PROBLEM TO BE SOLVED: To reduce a threshing load in a threshing chamber and increase the processing capacity of a thresher.SOLUTION: A plurality of support members (25) for supporting threshing teeth (20) are arranged at intervals in a circumferential direction around a threshing cylinder shaft (26), and a cylindrical barrel part (27) covering the threshing cylinder shaft (26) is provided inside a space surrounded by the plurality of support members (25). The barrel part (27) is formed as a cylinder or square cylinder. Plate-like members (45) for generating wind are erected from an outer peripheral surface of the barrel part (27). Furthermore, the barrel part (27) is formed as a square cylinder, and the plate-like members (45) are erected from a plane part (28) of the square cylinder. A base part of the plate-like member (45) is fixed to the outer peripheral surface of the barrel part (27), and a distal end part of the plate-like member (45) is supported on the support member (25) side.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】扱室内の脱穀負荷を軽減すると共に、脱穀装置の処理能力を高める。【解決手段】扱歯(20)を支持する複数の支持部材(25)を、扱胴軸(26)を中心とする円周方向に互いに間隔をおいて配置し、これら複数の支持部材(25)で囲われた空間内に、扱胴軸(26)を覆う筒状の胴部(27)を設ける。また、胴部(27)を円筒または角筒とする。また、胴部(27)の外周面から起風用の板状部材(45)を起立させる。また、胴部(27)を角筒とし、この角筒における平面部(28)から板状部材(45)を起立させる。また、板状部材(45)の基部を胴部(27)の外周面に固着し、この板状部材(45)の先端部を支持部材(25)側に支持する。【選択図】 図4
