PROBLEM TO BE SOLVED: To provide a root crop harvester capable of adjusting separately a vertical position of a pick-up device and a vertical position of a pull-out conveyance device and appropriately picking up a foliage part and pulling out a crop.SOLUTION: A root crop harvester includes: pull-out conveyance devices 24L, 24R pulling out and conveying a crop planted in a field and pick-up devices 38, 39 separating entangling of a foliage part of a crop and guiding a foliage part of a crop in a harvesting row to a holding conveyance action area of the pull-out conveyance devices 24L, 24R. A crop detection member 90 detecting conveyance of a crop is arranged in the pull-out conveyance devices 24L, 24R. A control device 100 receiving a detection result of the crop detection member 90 is arranged. A pick-up rotation member 94 rotating the pick-up devices 38, 39 vertically is arranged. The control device 100 operates the pick-up rotation member 94 and changes a pick-up position of the pick-up devices 38, 39 when the crop detection member 90 is brought into a non-detection state.SELECTED DRAWING: Figure 12COPYRIGHT: (C)2018,JPO&INPIT【課題】 引起し装置の上下位置を引抜搬送装置の上下位置と別個に調節可能とし、茎葉部の引起しと作物の引き抜きを適正に行うことが可能な根菜類収穫機を提供すること。【解決手段】 圃場に植生する作物を引き抜いて搬送する引抜搬送装置24L,24Rを設け、作物の茎葉部の絡み合いを分離すると共に収穫条の作物の茎葉部を引抜搬送装置24L,24Rの挟持搬送作用域に案内する引起し装置38,39を設けた根菜類収穫機において、引抜搬送装置24L,24Rに作物の搬送を検知する作物検知部材90を設け、作物検知部材90の検知結果を受ける制御装置100を設け、引起し装置38,39を上下回動させる引起し回動部材94を設け、制御装置100は、作物検知部材90が非検知状態になると引起し回動部材94を作動させて引起し装置38,39の引起し位置を変更する構成とする。【選択図】 図12
