PROBLEM TO BE SOLVED: To provide a combine harvester for improving the transfer position of a grain culm to be transported by a grain culm supply transport device having a thresher.SOLUTION: A reaper (4) is equipped with a transport device (H) for transporting reaped grain culm toward a thresher (3). On the lateral side of the thresher (3), there is disposed a grain culm supply and transportation device (17) for receiving the clamp transported by the transport device (H) and feeding the same to the thresher (3). The grain culm supply and transportation device (17) is constituted of a supply and transportation chain (19) and a clamping lever (18) biased toward the supply and transportation chain (19), thereby to clamp and transport the grain culm. On the outer side of the transport starting portion of the supply and transportation chain (19), there is disposed a guide member (32) in a vertical plate shape for supporting the hill base of the grain culm. Moreover, the upper edge of the guide member (32) is partially positioned over the moving locus of the supply and transportation chain (19) thereby to seal the outer side face of a portion of the moving locus of the supply and transportation chain (19).COPYRIGHT: (C)2014,JPO&INPIT【課題】脱穀装置に備えた穀稈供給搬送装置によって搬送される穀稈の搬送姿勢を良好なものとする。【解決手段】刈取装置(4)には刈取った穀稈を脱穀装置(3)側へ向けて搬送する搬送装置(H)を備え、脱穀装置(3)の横側部には、搬送装置(H)により搬送された穀稈を受け継いで脱穀装置(3)に供給する穀稈供給搬送装置(17)を設け、穀稈供給搬送装置(17)は、供給搬送チェン(19)と供給搬送チェン(19)に向けて付勢した挾扼杆(18)とにより穀稈を挾持搬送する構成とし、供給搬送チェン(19)の搬送始端部の外側には穀稈の株元を支持する縦板状のガイド部材(32)を設ける。また、ガイド部材(32)の上縁の一部を、供給搬送チェン(19)の移動軌跡よりも上方に位置させ、供給搬送チェン(19)の移動軌跡の一部の外側面を隠す構成とする。【選択図】図5
