PROBLEM TO BE SOLVED: To solve a problem that an ear tip side of a reaped grain culm deviates in an ear tip conveyance device in manual threshing work and supply to a grain culm supply port of a threshing device is disturbed to cause occurrence of clogging.SOLUTION: In a combine, a root side of a grain culm reaped by a reaping device 4 is transferred from a root conveyance device 34A to a feed chain 12B arranged in a threshing device 3 and a supply chain 34C arranged in a machine body depth front part of the feed chain. A manual threshing restriction member 38 extending from a terminal side of the root conveyance device toward a front part of a holding rod 12A facing an upper side of the feed chain is configured to be switched between a state where the manual threshing restriction member is erected and rotated with a rotation support shaft 38b arranged at a terminal part of the root conveyance device as a center, a front upper part of the feed chain opens, and reaped grain culms can be supplied and a state where the manual threshing restriction member is lodged and rotated and a tip of the manual threshing restriction member approaches a front part of the holding rod to restrict supply of reaped grain culms. The manual threshing restriction member lodged and rotated presses a tip side holding rod 61 facing an upper side of the supply chain to the supply chain side.SELECTED DRAWING: Figure 11COPYRIGHT: (C)2018,JPO&INPIT【課題】手扱ぎ作業時に穂先搬送装置で刈取穀稈の穂先側が乱れて脱穀装置の穀稈供給口への供給が乱れて詰り発生の原因となる。【解決手段】刈取装置4で刈り取った刈取穀稈の株元側を株元搬送装置34Aから、脱穀装置3に備えたフィードチェン12Bと該フィードチェンの機体奥側前部に配置した供給チェン34Cに引き継ぐコンバインにおいて、株元搬送装置の終端部側からフィードチェンの上側に対向する挟持杆12Aの前部に向けて延在する手扱ぎ規制部材38を、株元搬送装置の終端部に設けた回動支軸部38bを中心として起立回動させてフィードチェンの前部上方を開放して刈取穀稈の供給を可能とする状態と、手扱ぎ規制部材を倒伏回動させて該手扱ぎ規制部材の先端部を挟持杆の前部に近接させて刈取穀稈の供給を規制する状態とに切り換え自在に構成し、倒伏回動させた手扱ぎ規制部材によって供給チェンの上側に対向する穂先側挟持杆61を供給チェン側に押圧するコンバイン。【選択図】図11
