PROBLEM TO BE SOLVED: To provide a thresher which is improved in threshing performance by making air generated in a threshing chamber stably flow to a prescribed direction by the rotation of threshing teeth, in the thresher comprising: a threshing cylinder which is rotationally driven around a rotating shaft in a vertical direction and the threshing teeth which are aligned in parallel along an axial direction of the threshing cylinder.SOLUTION: A thresher comprises: a threshing cylinder 6 which is rotationally driven around a rotating shaft 31 in a vertical direction and a transfer body 4 which holds and transfers plant food sides. A plurality of the threshing teeth 32A aligned in parallel along the rotating shaft 31 of the threshing cylinder 6 and forming a comb shape are arranged at the external peripheral face side of the threshing cylinder 6, and a rotation direction of the threshing cylinder 6 is set so that the moving direction of the threshing teeth 32A at the transfer body 4 side becomes a direction opposite to a transfer direction of grain culms by the transfer body 4. A guide member 50 having guide faces 50a, 50b and 50c along rotation traces of tips of the threshing teeth 32A is arranged at a side opposite to the transfer body 4 with the threshing cylinder 6 in a threshing chamber 2 sandwiched, and air which is generated accompanied by the rotation of the threshing teeth 32A is introduced by the guide member 50.COPYRIGHT: (C)2014,JPO&INPIT【課題】上下方向の回転軸回りに回転駆動する扱胴と、扱胴の軸方向に沿って並列される扱歯を備えた脱穀装置において、扱歯の回転によって扱室内に発生するエアを安定的に所定方向に流動させることにより、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している。【解決手段】上下方向の回転軸31回りに回転駆動される扱胴6と、株元側を保持して搬送する搬送体4とを備え、該扱胴6の回転軸31方向に沿って並列されて櫛状をなす複数の扱歯32Aを扱胴6の外周面側に設け、扱歯32Aの搬送体4側での移動方向が搬送体4による穀稈の搬送方向に対して反対方向となるように扱胴6の回転方向を設定した脱穀装置において、扱室2内における扱胴6を挟んだ搬送体4の反対側に、扱歯32A先端の回転軌跡に沿う案内面50a,50b,50cを有するガイド部材50を設け、該ガイド部材50により扱歯32Aの回転に伴って発生するエアを導風した。【選択図】図3
