PROBLEM TO BE SOLVED: To improve the safety of manual threshing work of a worker.SOLUTION: The combine harvester is configured to change over between: a regulation state where a threshing regulation member (140) extending rearward from a terminal end of a conveyance device (34) in a reaper (4) side is inclined with the rear thereof gradually raised, so that the rear part (140B) of the threshing regulation member (140) is located outward a machine body with respect to a feed chain (12B) in plane view, and the threshing regulation member (140) is rotationally turned downward to decrease an interval between the rear part of the threshing regulation member (140) and a front part of a clamping rod (12A), thus regulating supply of threshed grain culm to a feed chain (12B) and a non-regulation state where the threshing regulation member (140) is upward rotationally operated, while holding a grip (140C) provided in the threshing regulation member (140) side, to increase the interval between the rear part of the threshing regulation member (140) and the front part of a clamping rod (12A), thus allowing the supply of the threshed grain culm to the feed chain (12B).SELECTED DRAWING: Figure 21COPYRIGHT: (C)2017,JPO&INPIT【課題】作業者の手扱ぎ作業の安全性を高める。【解決手段】刈取装置(4)側の搬送装置(34)の終端部から後方に向けて延出された手扱ぎ規制部材(140)を後上がりに傾斜させ、手扱ぎ規制部材(140)の後側部(140B)を平面視でフィードチェン(12B)よりも機体外側に位置させ、手扱ぎ規制部材(140)を下方向に回動させて手扱ぎ規制部材(140)の後部と挟持杆(12A)の前部との間隔を縮小してフィードチェン(12B)への手扱ぎ穀稈の供給が規制される規制状態と、手扱ぎ規制部材(140)側に備えたグリップ(140C)を把持して手扱ぎ規制部材(140)を上方向に回動操作して手扱ぎ規制部材(140)の後部と挟持杆(12A)の前部との間隔を拡大してフィードチェン(12B)への手扱ぎ穀稈の供給が許容される非規制状態とに切り換え可能な構成とする。【選択図】図21
