PROBLEM TO BE SOLVED: To provide a thresher which prevents large dusts from remaining in a processing cylinder and improves the throughput of the processing cylinder.SOLUTION: A thresher comprises a threshing cylinder, a plurality of threshing teeth, a grain culm carrier mechanism, and a cut-ear processing device 29. The threshing cylinder rotates about an axis line. The threshing teeth are formed flat nearly parallel to the axis line of the threshing cylinder and tapering off toward the tip, and arranged around the threshing cylinder. The grain culm carrier mechanism transports grain culms along the axis line of the threshing cylinder. The cut-ear processing device 29 includes a processing cylinder 30 disposed parallel to the threshing cylinder, into which material to be processed, which is generated in the threshing cylinder, is inserted. The cut-ear processing device 29 is disposed opposing to a circumferential surface of the processing cylinder 30 and includes a processing material guide member 65 disposed so as to follow a spiral with the axis of the processing cylinder as the center.COPYRIGHT: (C)2014,JPO&INPIT【課題】大きな塵などが処理胴に滞留することを防止し、当該処理胴の処理効率を改善させた脱穀装置を提供する。【解決手段】脱穀装置は、扱胴と、複数の扱歯と、穀稈搬送機構と、穂切れ処理装置29と、を備える。扱胴は、軸線回りに回転する。扱歯は、扱胴の軸線と略平行な扁平状に形成されるとともに、先端に向けて細くなるように形成され、扱胴の周囲に設けられる。穀稈搬送機構は、扱胴の軸線に沿って穀稈を搬送する。穂切れ処理装置29は、扱胴と平行に配置された処理胴30を有し、扱胴で発生した被処理物が投入される。そして、穂切れ処理装置29は、処理胴30の周面に対向して配置され、かつ前記処理胴30の軸を中心とする螺旋に沿うように配置された被処理物案内部材65を備える。【選択図】図7
