PROBLEM TO BE SOLVED: To smooth grain culm conveyance by a threshing feed chain and facilitate feeding of manually-threshed grain culm to the threshing feed chain.SOLUTION: The combine harvester includes a manual-threshing regulation member (18), and is configured to hold a vertical gap between a conveyance start end of the threshing feed chain (8) in the regulation state and the manual-threshing regulation member (18), the vertical gap served as a conveyance passage of grain culm that is delivered from a reaper (3) side to the threshing feed chain (8) side. The manual-threshing regulation member (18) is attached to vertically rotationally turn about a horizontal shaft (22) of the reaper (3) side, where the regulation state is released by ascending rotational turning of the manual-threshing regulation member (18). The combine harvester further includes a delivery guide rod (23) that elastically presses the grain culm delivered from the reaper (3) to the conveyance start end of the threshing feed chain (8), against the upper face of the conveyance start end of the threshing feed chain (8), and the front end of the delivery guide rod (23) is supported by the reaper (3) side.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】脱穀フィードチェンによる穀稈搬送を円滑化するとともに、この脱穀フィードチェンへの手扱ぎ穀稈の供給を容易化する。【解決手段】手扱ぎ規制部材(18)が備えられ、規制状態における脱穀フィードチェン(8)の搬送始端部と手扱ぎ規制部材(18)との間には、刈取装置(3)側から脱穀フィードチェン(8)側へ引き継がれる穀稈の搬送通路となる上下方向の隙間が維持される構成とし、手扱ぎ規制部材(18)が、刈取装置(3)側の横軸(22)を中心として上下回動自在に取り付けられ、該手扱ぎ規制部材(18)の上昇回動によって、規制解除状態が現出される構成とし、刈取装置(3)側から脱穀フィードチェン(8)の搬送始端部に引き継がれる穀稈を、該脱穀フィードチェン(8)の搬送始端部上面に弾性的に押圧する引継ぎガイド杆(23)が備えられ、該引継ぎガイド杆(23)の前端部が刈取装置(3)側に支持される。【選択図】図3
