PROBLEM TO BE SOLVED: To solve a problem of providing a sensor for detecting jamming in a grain-lifting device which may degrade maintainability of a vicinity of the grain-lifting device.SOLUTION: A thresher (3) is provided on one side of right-left sides on a machine frame (1), and a grain tank (5) is provided on the other side. The thresher (3) includes: a threshing chamber (15) axially having a drum (20) a swing-sorting shelf (22) that is provided below the drum (20) and that sorts grains and foreign substances by a blow from a fan (21) and a reciprocate swing in a blowing direction and a grain-lifting device (26) which transfers the grains sorted by the swing-sorting shelf (22) to the grain tank (5). At an upper end of the grain-lifting device (26), a support member (46) is provided which supports a pre-cleaner (45) for supplying outside air to an engine (18), and a sensor (33) for detecting jamming of the grain-lifting device (26) is provided to the support member (46).SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】揚穀装置の詰まりを検出するセンサを設けた場合、揚穀装置付近のメンテナンス性が悪化するという課題がある。【解決手段】機体フレーム(1)上の左右一側に脱穀装置(3)を設け、他側にグレンタンク5を設け、脱穀装置(3)は、扱胴(20)を軸装した扱室(15)と、この扱胴(20)の下方に配置され、唐箕(21)の送風と送風方向の往復揺動により穀粒と異物とを選別する揺動選別棚(22)と、該揺動選別棚(22)によって選別された穀粒をグレンタンク(5)に移送する揚穀装置(26)を備え、揚穀装置(26)の上端部に、エンジン(18)に外気を供給するプレクリーナー(45)を支持する支持部材(46)を設け、この支持部材(46)に揚穀装置(26)の詰まりを検出するセンサ(33)を設ける。【選択図】図2
