PROBLEM TO BE SOLVED: To provide a threshing device including a threshing cylinder rotationally driven around a longitudinal shaft, which prevents grain threshed by the threshing cylinder from being scattered to the outside of a machine, and can make the grain fall to the most helix side efficiently.SOLUTION: A threshing device includes a threshing chamber 4 where at least a tip side of a reaped grain culm is introduced, and a threshing cylinder 3 rotationally driven around a longitudinal rotating shaft 36 in the threshing chamber 4 and provided with comb-shaped threshing teeth 37A in a peripheral surface. A plate-like body 61 formed in a curved or bent shape so as to conform in a rotation locus at the tip part of the threshing teeth 37A of the threshing cylinder 3 in a plan view is disposed in the outer circumferential side of the threshing cylinder 3. The plate-like body 61 is formed with multiple holes so as to permit passage of the grain threshed from the grain culm, or formed in a mesh.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】縦方向の軸回り回転駆動する扱胴を備えた脱穀装置において、扱胴によって脱穀された穀粒が機外へ飛散することを防止するとともに、該穀粒を効率的に一番ラセン側に落下させることのできる脱穀装置を提供することを課題としている。【解決手段】刈取られた穀稈の少なくとも穂先側が導入される扱室4と、該扱室4内で縦方向の回転軸36回りに回転駆動するとともに周面に櫛状の扱歯37Aが設けられた扱胴3とを備えた脱穀装置において、平面視で前記扱胴3の扱歯37Aの先端部の回転軌跡に沿うように湾曲又は屈曲形成した板状体61を該扱胴3の外周側に配置し、該板状体61は、上記穀稈から脱粒された穀粒の通過を許容するように複数の孔が形成され、或いは、網状に形成した。【選択図】図5
