PROBLEM TO BE SOLVED: To provide a root crop harvester for burying ridge furrows while performing a harvesting work of a crop plant and for suppressing inclinations of a machine body in the transverse directions when travel devices pass the ridge furrows so that the extracting work height of an extracting transport device is hardly varied.SOLUTION: A root crop harvester comprises: right and left travel devices 6L and 6R for running on a farm field an extracting transport device 24 provided on one transverse side of the machine body for extracting crop plants from the farm field by an extracting and action part at the front part of the machine body and transporting the crop plants and a groove burying device 214 for gathering soil and burying the ridge furrows. The groove burying device 214 includes a first groove burying member 207a made more oblique toward the rear side of the machine body as it goes more backward, and a second groove burying member 207b having an oblique portion made more closer to one transverse side and a transverse extending portion extending in the transverse directions of the machine body as they go more backward. The first groove burying member 207a and the second groove burying member 207b are overlapped at their end portions, as seen in the front view of the machine body.COPYRIGHT: (C)2014,JPO&INPIT【課題】作物の収穫作業を行いながら畝溝を埋め、走行装置が畝溝を通過するときに機体の左右方向の傾斜を抑え、引抜搬送装置の引抜作業高さが変化しにくい根菜類収穫機を提供する。【解決手段】圃場を走行する左右の走行装置6L,6Rを設け、機体の左右一側に機体前部の引抜作用部で作物を圃場から引き抜き搬送する引抜搬送装置24を設け、土を寄せて畝溝を埋める溝埋め装置214を設けた根菜類収穫機において、溝埋め装置214は、機体後側ほど左右一側に向かう斜め姿勢の第1溝埋め部材207aと、機体後側ほど左右一側に向かう斜め部と機体の左右方向に延びる左右延設部を有する第2溝埋め部材207bを設け、機体正面視で第1溝埋め部材207aと第2溝埋め部材207bの端部を重ね合わせる構成とする。【選択図】図2
