PROBLEM TO BE SOLVED: To provide a combine harvester for supplying a threshed grain culm smoothly to a thresher while reducing the disturbance in the transportation position.SOLUTION: A reaping device (4) is driven in synchronism with the travel speed of a travel unit (2). A thresher (3) is equipped on its lateral side portion with a grain culm supply and transport device (17) for feeding the grain culm transferred by a transportation device (H) on the side of the reaping device (4) to the thresher (3). The grain culm supply and transportation device (17) is constituted to clamp and transport the grain culm by a supply and transport chain (19) and a clamping lever (18). On the inner side of the transport starting end portion of the grain culm supply and transport device (17), there is disposed a takeover chain (30) which is substantially parallel to the supply and transport chain (19), as viewed in top plan view, and driven at a speed synchronized with the transfer velocity of the transportation device (H) to takeover the grain culm from the transportation device (H). At a portion on the outer side of the supply and transport chain (18) on the front side of the clamp starting end portion of the clamping lever (18), there is disposed a guide member (32) for supporting the root of the grain culm.COPYRIGHT: (C)2014,JPO&INPIT【課題】脱穀穀稈の搬送姿勢の乱れを少なくし、脱穀装置へ円滑に供給する。【解決手段】刈取装置(4)を走行装置(2)の走行速度に同調して駆動する構成とし、脱穀装置(3)の横側部には、刈取装置(4)側の搬送装置(H)で搬送された穀稈を脱穀装置(3)に供給する穀稈供給搬送装置(17)を備え、穀稈供給搬送装置(17)は、供給搬送チェン(19)と挾扼杆(18)とにより穀稈を挾持搬送する構成とし、穀稈供給搬送装置(17)の搬送始端部の内側には、平面視において供給搬送チェン(19)と略平行で搬送装置(H)の搬送速度に同調した速度で駆動されて搬送装置(H)から穀稈を引き継ぐ引継チェン(30)を設け、挾扼杆(18)の挾持始端部よりも前側の供給搬送チェン(19)の外側の部位に穀稈の株元を支持するガイド部材(32)を設ける。【選択図】図5
