PROBLEM TO BE SOLVED: To reduce the threshing load in a threshing chamber and to enhance the processing capability of a threshing device.SOLUTION: A threshing cylinder 21 pivotally supported by a threshing cylinder shaft is arranged inside a threshing chamber 22, a plurality of support members 25 supporting threshing teeth 20 are arranged in the threshing cylinder 21 at intervals in a circumferential direction with a threshing cylinder shaft as a center, and an oscillation sorting shelf 11 is arranged in a lower side of the threshing chamber 22 in a threshing device. A cylinder part covering the threshing cylinder shaft is arranged in an inner space of the threshing cylinder 21 surrounded by the plurality of support members 25 and a plate-like member 45 is arranged between an outer peripheral face of the cylinder part and the support members 25. The plurality of support members 25 and plate-like member 45 are arranged along a shaft center direction of the threshing cylinder shaft and the inner space 29 of the threshing cylinder 21 formed in the outer periphery of the cylinder part is partitioned by the plate-like member 45.SELECTED DRAWING: Figure 2COPYRIGHT: (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】扱室22の内部に、扱胴軸で軸支された扱胴21を設け、扱胴21には、扱歯20を支持する複数の支持部材25を、扱胴軸を中心とする円周方向に互いに間隔をおいて設け、扱室22の下側に揺動選別棚11を設けた脱穀装置において、複数の支持部材25によって囲われた扱胴21の内部の空間内に、扱胴軸を覆う胴部を設け、この胴部の外周面と支持部材25の間に板状部材45を設ける。また、複数の支持部材25と板状部材45を、扱胴軸の軸心方向に沿わせて設け、胴部の外周に形成された扱胴21の内部空間29を板状部材45で仕切る構成とする。【選択図】図2
