PROBLEM TO BE SOLVED: To provide a thresher in which a plurality of comb-like threshing tooth rows formed in an axial direction of a threshing drum are arranged in a circumferential direction of the threshing drum, in which a carrier for carrying a grain culm of which ear tips toward a threshing room in a direction crossing to the axial direction of the threshing drum in a side view is arranged in a lateral side of the threshing room, and which reduces a threshing load and is improved in threshing ability.SOLUTION: By arranging each of threshing teeth 22 in a manner that a formation position of threshing teeth 22 in at least one of threshing tooth rows 21 is displaced in an axial direction of the threshing drum 14 with respect to a formation position of the threshing teeth 22 in at least one of the other threshing tooth rows 21, rotation loci of the threshing teeth 22 in the two threshing tooth rows 21, 21 become different from each other.COPYRIGHT: (C)2016,JPO&INPIT【課題】扱胴の軸方向に形成された櫛状の扱歯列を、該扱胴の周方向に並べて複数設け、穂先を扱室内を向けた穀稈を、側面視で、扱胴の軸方向に交差する方向に搬送する搬送体を、扱室の側方に配置し、脱穀負荷を低減させつつ、脱穀性能を向上させた脱穀装置を提供することを課題とする。【解決手段】少なくとも1つの扱歯列21における扱歯22の形成位置がその他の少なくとも1つの扱歯列21における扱歯22の形成位置に対して上記扱胴14の軸方向にずれるように各扱歯22を配置することにより、該2つの扱歯列21,21における扱歯22の回転軌跡を互いに異ならせる。【選択図】図5
