PROBLEM TO BE SOLVED: To prevent various kinds of corms such as potatoes scooped up by means of a digging blade from falling from a gap between the digging blade and a coulter midway through the transfer of the corms to a conveyor.SOLUTION: An anti-fall plate 1 is formed in a nearly right-angled triangular shape its longer side is bent and forms a hole, so as to serve as a digging blade-mounting part 7 and its shorter side is bent in a position below its top so as to serve as a bending regulating plate-mounting part 10, in which a slot is formed. A bending regulating plate 2 is formed in a nearly parallelogram shape a hole is formed on one side in accordance with a position of the slot of the regulating plate-mounting part a slot is formed on the side facing the one side, so that a side wall fixing plate-mounting part 12 can be constituted. A side wall fixing plate 3 is formed in a nearly parallelogram shape a hole is formed on one side in accordance with a position of the slot of the side wall fixing plate-mounting part of the regulating plate and a hole for fixation to a side wall of a conveyor is formed on the opposed side in the state of being bent in parallel with the above side.COPYRIGHT: (C)2008,JPO&INPIT【課題】掘取刃により掬い上げたジャガイモなどの各種芋が、コンベアへの移送過程で掘取刃とコールターの隙間から落下しないようする。【解決手段】落下防止板1は略直角三角形形状とし長辺を曲げ孔を形成し掘取刃取付部7とし、短辺は頂部より下がった位置より曲げ調整板取付部10とし、調整板取付部には長孔を形成し、調整板2は略平行四辺形とし一辺には調整板取付部の長孔の位置に合わせて孔を形成し、対向する辺には長孔を形成して側壁固定板取付部12とし、側壁固定板3は略平行四辺形とし一辺には調整板の側壁固定板取付部の長孔の位置に合わせて孔を形成しこの辺と並行に折り曲げ、対向する辺にはコンベアの側壁へ固定するための孔を形成した。【選択図】 図1
