PROBLEM TO BE SOLVED: To instantaneously detect and cope with clogging of a conveyance passage in a mid-flow of feeding reaped grain culms to a thresher by conveyers.SOLUTION: The combine harvester includes an adjustable conveyer (18) that takes over merged grain culms conveyed by a right plant foot conveyer (16a) and a left plant foot conveyer (16b), to a takeover conveyer (5) in a thresher (2) side. The adjustable conveyer (18) vertically rotationally turns a part of a terminal side, with a conveyance leader side used as a fulcrum, to adjust a threshing depth of the grain culms to be fed to the thresher (2). The adjustable conveyer (18) comprises an adjusting chain (18a) for clampingly conveying the grain culms, and a clamping rod (18b) disposed facing the adjusting chian (18a), and includes a grain culm sensor (30) for detecting such a state that a part of the clamping rod (18b) in the conveyance leader side is separated from the adjusting chain (18a) by a prescribed amount.COPYRIGHT: (C)2014,JPO&INPIT【課題】コンバインにおいて、刈取穀稈を搬送装置で脱穀装置に供給する搬送途中の搬送通路に詰りが発生したことをいち早く検出して対処できるようにする。【解決手段】右株元搬送装置(16a)及び左株元搬送装置(16b)で搬送されて合流した穀稈を脱穀装置(2)側の引継搬送装置(5)へ引継ぐ調節搬送装置(18)を設け、調節搬送装置(18)は、搬送始端側を支点として終端側の部位を上下に回動させることで脱穀装置(2)に供給される穀稈の扱深さを調節する構成としたコンバインにおいて、調節搬送装置(18)は、穀稈を挟持搬送する調節チェン(18a)と調節チェン(18a)に対向配置される挟持杆(18b)とで構成し、挟持杆(18b)の搬送始端側の部位が調節チェン(18a)に対して所定量離間した状態を検出する穀稈センサ(30)を設ける。【選択図】図7
