PROBLEM TO BE SOLVED: To provide a device of shaking off soil/mud from roots of crops with the soil/mud attached to the roots with neither using water nor damaging the roots.SOLUTION: A crop conveyance device includes: a pair of left/right closely-provided endless belts H, holding stem/leaf parts of crops P with roots, with the stem/leaf parts held between the belts, obliquely upward at a conveyance rate V； a horizontal rotary shaft H, whose left/right direction is horizontal, and which is provided at a position on a lower side rof a lower boundary surface Hof a passage area Hthrough which the roots PR of crops P on the lower side of the pair of left/right endless belt pass； a rotary elastic body Hjournaled to the rotary shaft； and rotational means for rotationally turning the rotary shaft. The crop conveyance device is actuated such that a rotation rate ω of the rotary shaft Hsatisfies 2 V>；ω*r>；V.SELECTED DRAWING: Figure 7【課題】 本発明は、根に土泥を付着させた農作物の根から土泥を水を使わずに且つ根を傷めること少なく振い落す装置を提供する。【解決手段】 根付の農作物Ｐの茎葉部分をベルト間に把持して移送速度Ｖ０で斜め上方に向って移送する左右一対の接近させた無端ベルトＨ１０と、同左右一対の無端ベルトの下方の農作物Ｐの根ＰＲが通過する通過領域Ｈ２の下方境界面Ｈ２２の下方ｒ０の位置に設けられた左右方向の水平な回転軸Ｈ３と、同回転軸に軸着された回転弾性体Ｈ４と、同回転軸を回動する回動手段とを備え、回転軸Ｈ３の回転速度ωを２Ｖ０＞ω・ｒ０＞Ｖ０を満足するように作動させる。【選択図】図７
