PROBLEM TO BE SOLVED: To provide a subterranean-stemmed crop harvester that solves the problem, wherein with the hairy roots of a subterranean-stemmed crop stuck in soil, crops harvesting operation comes to a halt midway, since the harvester becomes adhered with soil.SOLUTION: The subterranean-stemmed crop harvester comprises a pulling conveyor part 6, set up inclined rearwardly upward for gripping stems/leaves L of a subterranean-stemmed crop C for pulling off the crop C a root-cutoff blade 7 for cutting off part of the hairy roots R of the crop C in the soil a stems/leave cutting part 8, set up on the conveyor part 6 and functioning to cut the stems/leaves L and the subterranean stems U of the crop C off each other, midway of conveying the crop C dug up a subterranean stem-receiving part 9, set up beneath the part 8 and functioning to catch the subterranean stems U dropped separated and a hairy root-cutoff part 10, having a bulb mover 10a which is loadable with the respective subterranean stems U and a hairy stem-cutoff blade 10b for cutting hairy roots R and stems S off the subterranean stems U. In this harvester, an operators riding part 5 is set up, adjoining a bulb mover 10a.COPYRIGHT: (C)2009,JPO&INPIT【課題】地下茎作物の毛根部には土が付着しているため土により装置の詰まりが発生して作業が途中で停止してしまう課題があった。【解決手段】後上がりに斜設され地下茎作物Cの茎葉部Lを挟持して抜き取る引抜き搬送コンベア部6と、土中の地下茎作物の毛根部Rの一部を切断する根切刃7と、引抜き搬送コンベア部6に設けられ掘り上げた地下茎作物Cを搬送途中に地下茎作物Cの茎葉部Lと地下茎部Uとを切断する茎葉部切断部8と、茎葉部切断部8の下方に設けられ分離落下した地下茎部Uを受け止める地下茎受け部9と、各地下茎部Uを載置可能な球根移動体10a及び地下茎部Uから毛根Rと茎Sを切断する毛根茎切断刃10bとを有する毛根切断部10とを設けるとともに、作業者の乗車部5を毛根切断部10の球根移動体10aに隣接して設けた地下茎作物の収穫機による。【選択図】図1
