PROBLEM TO BE SOLVED: To provide a grain culm transport device capable of easily eliminating grain culm clogging by making a vertical adjusting mechanism of a rotating body in a transport upstream portion compact. An object of the present invention is to arrange at least a part of a plurality of connecting members (35) and a rotation axis of a rotating body (12) in a line in a stretching direction of a conveying surface (10D) of a grain culm. , The drive speed of the chain (15) is increased when the rotation speed of the auger device (3C) is less than the first lower limit speed and the moving speed of the chain (15) is not less than the second lower limit speed, Will be solved. [Selection diagram] Fig. 5【課題】搬送上流部の回転体の上下調節機構をコンパクトにし、穀稈詰まりを容易に解消できる穀稈搬送装置を提供する。【解決手段】本発明の課題は、穀稈の搬送面（１０Ｄ）の延伸方向において、複数の連結部材（３５）の少なくとも一部と回転体（１２）の回転軸心が並ぶように配置され、オーガ装置（３Ｃ）の回転速度が第１下限速度未満であり、かつ、チェン（１５）の移動速度が第２下限速度以上である場合に、チェン（１５）の駆動速度を増速する、ことにより解決される。【選択図】図５
