PROBLEM TO BE SOLVED: To provide a combine harvester which can retain its threshing performance even if the harvester running speed rises.SOLUTION: A combine harvester comprises a running vehicle body, a clipping portion 93, a handling drum 16, a plurality of handling teeth 22 and a grain culm carrier mechanism 11. The handling teeth 22 are disposed around the handling drum 16. The grain culm carrier mechanism 11 receives the grain culm clipped by the clipping portion 93, and transports the received grain culm along the axis line 17 of the handling drum 16. The clipping speed of the grain culm by the clipping portion 93 and the carrying speed of the grain culm by the grain culm carrier mechanism 11 vary in association with the running speed of the running vehicle body. The handling teeth 22 are so formed in a flat shape substantially parallel to the axial line 17 of the handling drum 16 as to become thinner toward the leading end. Moreover, the handling teeth 22 are arranged in plurality in a direction parallel to the axial line 17 of the handling drum 16 so that a V-shaped groove is formed to diverge toward the leading end between the adjoining handling teeth 22.COPYRIGHT: (C)2014,JPO&INPIT【課題】車速が上昇しても脱穀性能が低下しないコンバインを提供する。【解決手段】コンバインは、走行車体と、刈取部93と、扱胴16と、複数の扱歯22と、穀稈搬送機構11と、を備える。扱歯22は、扱胴16の周囲に設けられる。穀稈搬送機構11は、刈取部93が刈り取った穀稈を受け取って、扱胴16の軸線17に沿って搬送する。刈取部93による穀稈の刈取速度と、穀稈搬送機構11による穀稈の搬送速度と、が走行車体の走行速度に連動して変化する。扱歯22は、扱胴16の軸線17と略平行な扁平状に形成されるとともに、先端に向けて細くなるように形成される。そして、複数の扱歯22が扱胴16の軸線17と平行な方向に複数並んで配置されることにより、隣接する扱歯22同士の間に、先端に向けて広がるV型溝が形成されている。【選択図】図8
