PROBLEM TO BE SOLVED: To provide a green onion harvester which can scrape off not only adhering clods positioned in the lower part of root and stalk parts of green onions but also adhering clods positioned on the side of the root and stalk parts of the green onions by varying projecting heights of respective projecting pieces so that tip end parts of a plurality of the projecting pieces projecting on an outer peripheral surface of a rotating body follow the root and stalk parts.SOLUTION: A harvesting part is equipped with a digging part for digging green onions, a transporting part for transporting the green onions dug by the digging part to the back, and a scraping part for scraping off a clod adhering to root and stalk parts of the green onions while transporting by the transporting part as respective operating parts. In the scraping part, an axial line of a cylindrical rotating body is arranged in a direction perpendicular to a transporting direction of the transporting part, and the rotating body is rotatable about the axial line. On an outer peripheral surface of the rotating body, a plurality of scraping projecting pieces are radially projected at intervals respectively in the circumferential direction and the axial direction, and the respective projecting pieces have projecting heights that are varied so that tip end parts of the respective projecting pieces follow the root and stalk parts.COPYRIGHT: (C)2016,JPO&INPIT【課題】回転体の外周面に多数突設した各突片の先端部が根茎部に沿うように、各突片の突出高さに変化をもたせることで、ねぎの根茎部の下方に位置する付着土塊のみならず、ねぎの根茎部の側方に位置する付着土塊も掻き落とすことができるねぎ収穫機を提供すること。【解決手段】収穫部は、各作業部として、ねぎを掘り起こす掘り起こし部と、掘り起こし部で掘り起こしたねぎを後方へ搬送する搬送部と、搬送部により搬送しながらねぎの根茎部に付着している土塊を掻き落とす掻き落とし部と、を具備する。掻き落とし部には、搬送部の搬送方向に対して直交する方向に筒状の回転体の軸線を向けて配置するとともに、その軸線廻りに回転体を回転可能とした。回転体の外周面には、その周方向と軸線方向にそれぞれ間隔をあけて多数の掻き落とし用の突片を放射状に突設するとともに、各突片は、それらの先端部が根茎部に沿うように各突片の突出高さに変化をもたせた。【選択図】図10
