PROBLEM TO BE SOLVED: To provide a threshing cylinder which can prevent intrusion of reaped grain culm to an inner space and can facilitate maintenance and/or replacement of a threshing tooth frame.SOLUTION: The threshing cylinder includes: a threshing cylinder body including a front side plate and a rear side plate fastened on a threshing cylinder shaft and a shield plate fastened on the front side plate and rear side plate so as to surround the threshing cylinder shaft and plural threshing tooth frames including a long support bar and plural threshing teeth arranged along a longitudinal direction of the support bar at intervals. In a state in which the plural threshing teeth are extended outward in a radial direction from the support bar, the plural support bars are detachably fastened on an outer surface of the shield plate so as to be arranged generally parallel to the threshing cylinder shaft at intervals in a circumference direction of the threshing cylinder shaft.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2017,JPO&INPIT【課題】内部空間への刈取穀稈の侵入を防止でき且つ扱歯フレームのメンテナンス及び/又は交換の容易化を図り得る扱胴を提供する。【解決手段】扱胴軸に固着された前側プレート及び後側プレートと前記扱胴軸の回りを覆うように前記前側プレート及び前記後側プレートに固着された遮蔽板とを含む扱胴本体と、長尺の支持バー及び前記支持バーの長手方向に沿って間隙を存しつつ配置された複数の扱歯とを含む複数の扱歯フレームとを備え、前記複数の扱歯が前記支持バーから径方向外方へ延びる状態で前記複数の支持バーが前記扱胴軸に略平行で且つ前記扱胴軸の周方向に間隔を存しつつ配置されるように、前記複数の支持バーが前記遮蔽板の外表面に着脱可能に固着されている。【選択図】図6
