PROBLEM TO BE SOLVED: To provide a satisfactory hitting and diffusing effect to a grain stalk by a support member itself supporting threshing teeth.SOLUTION: Support plate (18, 19) are respectively mounted on the front and the back of threshing cylinder shaft (12), and a plurality of support members (20) formed of plate bodies are mounted at spaces from each other in the circumferential direction around the threshing cylinder shaft (12) between the front and rear support plates (18, 19). Each support member (20) is planted with a plurality of threshing teeth (21), and the respective support members (20) are bent so that both ends (20a, 20b) of the respective support members (20) in the circumferential direction are located closer to the threshing cylinder shaft (12) relative to the intermediate part. The threshing teeth (21) are formed of plate bodies, and the base sides of the threshing teeth (21) are fitted to stride over the tops (M) of the support members (20).COPYRIGHT: (C)2012,JPO&INPIT【課題】扱歯を支持する支持部材自体によって、穀稈に十分な叩打、拡散効果を与えるものとする。【解決手段】扱胴軸(12)の前部及び後部に支持板(18,19)を夫々装着し、前後の支持板(18,19)の間には、板体からなる複数の支持部材(20)を扱胴軸(12)を中心とした円周方向に互いに所定の間隔を置いて装着し、各支持部材(20)には複数の扱歯(21)を植設し、円周方向における各支持部材(20)の両端部(20a,20b)が中間部よりも扱胴軸(12)に接近するように各支持部材(20)を屈曲形成する。また、扱歯(21)を板体で構成すると共に、扱歯(21)の基部側を支持部材(20)の頂点(M)を跨いだ状態で取り付ける。【選択図】 図3
