PROBLEM TO BE SOLVED: To provide a root crop harvester that is widely fitted to the planting interrow distance of crops in drawing work of root crops such as Japanese radishes, and can maximally rake lower leaves and reliably pull up them in a range of not touching the crops of an adjacent row.SOLUTION: A root crop harvester is configured by including left and right raising devices (3a, 3b) of a backward tilting posture for raising foliage of root crops so as to rake it from left and right, and a pullout conveying device (4) for bundling and holding the foliage and pulling up the crops from a field. The raising devices (3a, 3b) are configured such that endless belts (13a) with raising bodies (13b) projected in the whole circumference are wound on a drive rotating body (11) arranged in the top and bottom and a driven rotating body (12), at the left and right sides, respectively, and are disposed in an oppositely circulating manner to each other. One raising device (3a) switches a raking width by changeably configuring a circling radius of the lower end position of the endless belt (13a) to enable the reliable drawing of the crops.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】大根等の根菜類の引抜作業において、作物の植付け条間距離に幅広く適合して隣接条の作物に触れない範囲内で下葉を最大限に掻き込んで確実に引抜くことができる根菜類収穫機を提供する。【解決手段】根菜類収穫機は、根菜作物の茎葉部を左右から掻込むように引起こす後傾姿勢の左右の引起装置(3a,3b)と、前記茎葉部を集束保持して作物を圃場から引抜く引抜搬送装置(4)とを備えて構成され、前記引起装置(3a,3b)は、左右それぞれ、引起体(13b)を全周に突設した無端帯(13a)を上下配置の駆動回転体(11)と従動回転体(12)とに巻回して互いに対向周回可能に配置し、一方の引起装置(3a)は、前記無端帯(13a)の下端位置の周回半径を変更可能に構成することにより、掻込幅を切替えて作物の確実な引抜きを可能とするものである。【選択図】図3
