To provide a combine capable of smoothly transporting grains in a state of suppressing residence of grains, and capable of suppressing wear of an inner surface of a transport path in which grains are circulated in a short term.SOLUTION: A combine comprises on a grain transport device 6 for transporting grains which have been subjected to threshing processing on a threshing part 4: a lateral transport part 26 for transporting grains in a lateral direction； and a vertical transport part 27 for transporting the grains delivered from a transport termination part of the lateral transport part 26 upward. The lateral transport part 26 comprises: a lateral transport screw 28； and a lateral transport peripheral wall part for surrounding the lateral transport screw. The vertical transport part 27 comprises: a vertical transport screw 32； and a vertical transport peripheral wall part 34 for surrounding the vertical transport screw. On a coupling part 36, a rotation shaft core of the lateral transport screw 28 and a rotation shaft core of the vertical transport screw 32 cross in a state in which their positions are deviated along a radial direction of the lateral transport part 26, and the lateral transport screw 28 and the vertical transport screw 32 are arranged in a state in which outer end rotation loci thereof are overlapped without interference.SELECTED DRAWING: Figure 4【課題】穀粒を滞留しない状態で円滑に搬送することができるとともに、穀粒が流動する搬送通路の内面が短期間で摩耗しないようにすることが望まれていた。【解決手段】脱穀部４にて脱穀処理して得られた穀粒を搬送する穀粒搬送装置６に、穀粒を横方向に搬送する横搬送部２６と、横搬送部２６の搬送終端部から受け渡された穀粒を上方に向けて搬送する縦搬送部２７とが備えられ、横搬送部２６に、横搬送スクリュー２８と、その周囲を覆う横搬送周壁部とが備えられ、縦搬送部２７に、縦搬送スクリュー３２と、その周囲を覆う縦搬送周壁部３４とが備えられ、連結部３６において、横搬送スクリュー２８の回転軸芯と縦搬送スクリュー３２の回転軸芯とが、横搬送部２６の径方向に沿って位置がずれた状態で交差するとともに、横搬送スクリュー２８と縦搬送スクリュー３２とが、干渉することなく外端回転軌跡が重複する状態で設けられている。【選択図】図４
