PROBLEM TO BE SOLVED: To provide a root crop harvester enabling separate discharge of mud and suppression of discharge crop entrainment in a discharge guide part formed at a conveyance end of a crop conveyance device.SOLUTION: The root crop harvester includes a crop conveyance device 81 conveying crops in an inclined manner by rotational operation to a height position of a selection conveyance device 91 after passing the crops from a pull-up conveyance device 24 and then a residual leaf processing device 76 below the pull-up conveyance device 24. The crop conveyance device 81 is arranged with conveyance auxiliary projections 82 in a sectional division shape for assisting conveyance and preventing backflow of conveyance crops. A conveyance end of the crop conveyance device 81 is arranged in an attachable/detachable manner with: an entry prevention member 83 composed of spaces Q for passing the conveyance auxiliary projections 82 and guide parts 83a for guiding conveyance objects to be discharged and a pressing-back member 84 facing the spaces Q and discharging entered objects by pressing. Thereby, stable discharge is enabled.COPYRIGHT: (C)2016,JPO&INPIT【課題】作物搬送装置の搬送終端に形成した排出案内部における泥土の分離排出および排出作物の巻込み抑制を可能とする根菜類収穫機を提供する。【解決手段】根菜類収穫機は、引抜搬送装置(24)からその下方の残葉処理装置(76)を経た後、選別搬送装置(91)の高さ位置まで周回動作によって作物を勾配搬送する作物搬送装置(81)を備えて構成され、上記作物搬送装置(81)に搬送を補助して搬送作物の逆流を防止するための部分仕切状の搬送補助突起(82)を設けるとともに、この搬送補助突起(82)が通過するための隙間(Q)と搬送物を排出案内するガイド部(83a)とからなる進入防止部材(83)と、上記隙間(Q)に臨んで進入物を押し出して排出する押し返し部材(84)とを上記作物搬送装置(81)の搬送端に着脱自在に設けることにより、安定排出を可能とするものである。【選択図】図3
