PROBLEM TO BE SOLVED: To provide a root vegetable harvester so designed that: even if miscellaneous impurities are dropped from a separatory conveyor, they are not bitten on the driving mechanism of the separatory conveyor.SOLUTION: The root vegetable harvester is provided, being so designed that: either the left side or right side of the machine body is equipped with a pull conveyor 24 for pulling crops off the farm and conveying them up backwards, and there is provided a separatory conveyor 87 for taking over the crops from the pull conveyor 24 and conveying them from either the left or right side of the machine body. This root vegetable harvester is so constructed that: there are provided a driving rotator 134 for driving the separatory conveyor 87 and a driven rotator 136 just under the driving rotator 134 at a vertical interval L2, and a transmission endless body 137 is laid in a straight-line fashion ranging from the driven rotator 136 to the driving rotator 134 alternatively, there is provided the driven rotator 136 toward either the left or right side of the machine body off the driving rotator 134, and the transmission endless body 137 is laid ranging from the driven rotator 136 to the driving rotator 134 in such an upwardly inclined posture as to turn upward further as to either the left or right side of the machine body.COPYRIGHT: (C)2013,JPO&INPIT【課題】選別搬送コンベアから夾雑物を落下させても、夾雑物が選別搬送コンベアの駆動機構に噛み込むことのない根菜類収穫機を提供する。【解決手段】機体の左右一側に作物を圃場から引き抜いて後上方に搬送する引抜搬送装置24を設け、引抜搬送装置24から作物を引き継いで左右一側から左右他側に搬送する選別搬送装置87を設けた根菜類収穫機において、選別搬送装置87を駆動する駆動回転体134を設け、駆動回転体134の直下に上下間隔L2を空けて従動回転体136を設け、従動回転体136から駆動回転体134に亘って伝動無端体137を直線状に配置する構成、或いは駆動回転体134よりも左右一側寄りに従動回転体136を設け、従動回転体136から駆動回転体134に亘って伝動無端体137を左右他側ほど上方に向かう上方傾斜姿勢で配置して構成する。【選択図】 図3
