PROBLEM TO BE SOLVED: To provide a seedling-planting device of a transplanter, for relatively thick and slender seedlings such as the bare seedlings of Welsh onion, in the transplantation cultivation of field crops, in which soil does not enter a furrow opener from the upper side, even when thick and long seedlings are deeply planted, and soil does not enter the furrow opener from the upper side, even when the depth of plantation is adjusted.SOLUTION: The seedling-planting device of the transplanter is characterized by disposing thin cylindrical rims 15a on the outer peripheries of a pair of press wheels 15, disposing auxiliary plates 19 above the rear ends of both the side plates of a furrow opener 13, disposing a narrow cut furrow matching to the shape of the rim 15a of the press wheel 15 in the auxiliary plate 19 from the rear end, inserting a part of the rim 15a of the press wheel 15 into the inside of the furrow opener 13 through the cut furrow of the auxiliary plate 19, and transferring the auxiliary plate 19 with the rim 15a inserted into the cut furrow by the upward or downward adjustment of the press wheel 15.COPYRIGHT: (C)2013,JPO&INPIT【課題】 農作物の移植栽培で、長ネギの裸苗のように比較的細長い苗の苗植付装置に関し、太くて長い苗を深く植え付けてもでも開溝器の中に上から土が入らず、植付深さを調節しても開溝器の中に上から土が入らない移植機の苗植付装置提供する。【解決手段】 一対の鎮圧輪15の外周は薄い円筒状のリム15aとし、開溝器13の両側板の後端部上方に補助板19を設け、補助板19にはその後端から鎮圧輪15のリム15aの形状に合わせた細幅の切溝を設け、鎮圧輪15のリム15aの一部は補助板19の切溝を通って開溝器13の内側に入り込み、鎮圧輪15の上下調節により補助板19がその切溝に入り込んだリム15aにより移動する。【選択図】図4
