PROBLEM TO BE SOLVED: To transmit driving force efficiently in a grain culm conveyance device by reducing a possibility of being limited in arrangement.SOLUTION: A root conveyance device 77 conveying a reaped grain culm toward a machine body rear side in a grain culm conveyance device includes: a root side driving wheel 77A to which driving force is input； another guiding wheel 77B； and a root side endless rotation belt 77C. An ear tip conveyance device 78 includes: an ear tip side driving wheel 78A to which driving force is input； another guiding wheel 78B； and an ear tip side endless rotation belt 78C. The root side driving wheel 77A is arranged at a different position from the ear tip side driving wheel 78A in a view in a direction along a rotation axis of the root side driving wheel 77A. A driving force transmission mechanism 130 transmitting driving force between the root side driving wheel 77A and ear tip side driving wheel 78A is arranged.SELECTED DRAWING: Figure 21COPYRIGHT: (C)2018,JPO&INPIT【課題】穀稈搬送装置について、設置上の制約を受けるおそれを少なくして、駆動力を効率よく伝達できるようにすることが望まれていた。【解決手段】刈取穀稈を機体後方に向けて搬送する穀稈搬送装置における株元搬送装置７７に、動力が入力される株元側駆動輪７７Ａと、別の他の案内輪７７Ｂと、株元側無端回動帯７７Ｃと、が備えられ、穂先搬送装置７８に、動力が入力される穂先側駆動輪７８Ａと、別の他の案内輪７８Ｂと、穂先側無端回動帯７８Ｃとが、備えられ、株元側駆動輪７７Ａは、株元側駆動輪７７Ａの回転軸芯に沿う方向視で、穂先側駆動輪７８Ａと異なる箇所に設けられ、株元側駆動輪７７Ａと穂先側駆動輪７８Ａとの間で動力を伝達する動力伝達機構１３０が備えられている。【選択図】図２１
