COMBINE

To provide a combine in which a belt of a normal rotation drive unit of a feeder house of a reaping pretreatment unit can be easily replaced.SOLUTION: A combine comprises a first rotary shaft 22 which extends in a lateral direction on a rear part of a lateral wall of a feeder house. On a left end of the first rotary shaft 22, a first pulley 22E, to which normal rotation for moving a slat for transporting grain culm to a rear side from a front side, is transmitted, is supported. On a right end part of the first rotary shaft 22, a first gear 22A, to which reverse rotation for moving the slat from the rear side to the front side is transmitted, is supported. A second pulley 14A is supported on a right end of a first counter shaft 14, and a third pulley 14E for transmitting rotation to the first pulley 22E is supported on a left end of the first counter shaft 14, and between the second pulley 14A and the third pulley 14E on the first counter shaft 14, there are supported fourth pulleys 14B, 14C, 14D for transmitting rotation transmitted to the first counter shaft 14, and a first belt 24 is wound around the third pulley 14E and the first pulley 22E.SELECTED DRAWING: Figure 3 【課題】刈取前処理装置のフィーダハウスの正転駆動装置のベルトを容易に交換できるコンバインを提供する。【解決手段】フィーダハウスの左右壁の後部に左右方向に延在する第１回転軸２２を設け、第１回転軸２２の左端部に、穀稈を搬送するスラットを前方から後方に移動させる正転回転が伝動される第１プーリ２２Ｅを支持し、第１回転軸２２の右端部に、スラットを後方から前方に移動させる逆転回転が伝動される第１ギヤ２２Ａを支持し、第１カウンタ軸１４の右端部に第２プーリ１４Ａを支持し、第１カウンタ軸１４の左端部に第１プーリ２２Ｅに伝動する第３プーリ１４Ｅを支持し、第１カウンタ軸１４における第２プーリ１４Ａと第３プーリ１４Ｅの間に、第１カウンタ軸１４に伝動された回転を脱穀装置に伝動する第４プーリ１４Ｂ、１４Ｃ、１４Ｄを支持し、第３プーリ１４Ｅと第１プーリ２２Ｅに第１ベルト２４を巻回した。【選択図】図３
