PROBLEM TO BE SOLVED: To provide a seedling transplanter solving the problem that the design of attaching/detaching the end part of a front plate is troublesome in operation, and that the end part tends to be lost, tends to butt on the adjacent member in the design of folding and suspending the front plate, be damaged, and to constitute a hindrance.SOLUTION: The seedling transplanter is such that its seedling tank guide has the following construction: Along the seedling feed port 4 of a seedling tank 3 that makes a reciprocating motion transversely relative to a seedling taking port 2 on which a seedling planting tine acts, a front plate 5 functioning to receive and guide seedlings fed via the port 4 and forming the seedling taking port 2 is provided. Both of plate end parts 6 of the front plate 5 are designed to be movable, and are moved inside of the underside of the front plate center 7 and housed in a superimposed fashion.COPYRIGHT: (C)2008,JPO&INPIT【課題】 前板の板端部を着脱する形態は操作が面倒であり、この板端部が紛失しやすく、折り畳んで下方え垂下させる形態では隣接部材に当って損傷しやすく、邪魔になりやすい。【解決手段】 苗植爪の作用する苗取口2に対して左右横方向へ往復移動する苗タンク3の苗送出口4に沿って、この苗送出口4の送出苗を受けて案内すると共に前記苗取口2を形成する前板5を設け、この前板5の左右両端の板端部6を移動可能に設けると共に、この前板中央部7の下部内側へ移動させて重合状態に収納することを特徴とする苗植機の苗タンクガイドの構成とする。【選択図】 図1
