Problem to be solved: to solve the problem in which the root position of each vegetable is disordered in the preparation process of root cutting and leaf cutting in the first row, and the root vegetables are overlapped with each other in the preparation process of the root cutting and leaf cutting, etc.The root harvesting machine of the present invention comprises a pull-out portion 11 for pulling out the stem portion KS of the root vegetable K, which is vegetated in the field, and pulling it out from the left and right, and a conveying part 12 for transporting the root K which is taken from the drawing portion 11 backward. The trailing end of the drawing portion 11 is positioned so as to be overlapped with the lower side of the front end of the conveying portion 12. The conveying speed V1 of the pulling out portion 11 and the conveying speed V2 of the conveying portion 12 are given a velocity difference.Diagram【課題】1つの畝に複数条植生した根菜類を収穫する場合、搬送途次での根切り・葉切り等の調製工程で、根菜類が重なり合っているため互いに邪魔をし、各根菜類の切断位置が不揃いになる問題を解消する。【解決手段】本願発明の根菜収穫機は、圃場に植生した根菜類Kの茎葉部KSを左右から挟持して引き抜く引抜き部11と、引抜き部11から受け継いだ根菜類Kを後方に搬送する搬送部12とを備える。引抜き部11の後端側を搬送部12の前端下方側に上下に重複するように位置させる。引抜き部11の搬送速度V1と搬送部12の搬送速度V2とに速度差を持たせる。【選択図】図4
