PROBLEM TO BE SOLVED: To provide a seedling transplanter having a lever-type planting operation mechanism furnished with a gyration interlocking mechanism, and ensuring stable action of the planting part regardless of wrong operation of a planting, lifting, and lowering lever.SOLUTION: The seedling transplanter is provided with a steering member (4) to gyrate a traveling body, a planting part (6) supported by the traveling body in a vertically movable manner, a planting, lifting and lowering lever (8) to changeover the planting part (6) in the order of lifting, neutral, lowering and planting modes, and an automatic lifting and lowering mechanism (C) to move the planting, lifting and lowering lever (8) to the lifting and lowering positions interlocked with start and end of gyration by the steering member (4). The transplanter is further provided with a work detection member to detect the planting work of the planting part (6) and stop the motion of the automatic lifting and lowering mechanism (C) when the detected work does not match a prescribed continuing range.COPYRIGHT: (C)2013,JPO&INPIT【課題】レバー式植付操作機構に旋回連動機構を備える苗移植機において、植付昇降レバーの誤操作によることなく、植付部の安定動作を確保することができる苗移植機を提供する。【解決手段】苗移植機は、走行車体を旋回操作する操舵部材(4)と、走行車体に昇降可能に支持した植付部(6)と、この植付部(6)の上昇、中立、下降、植付の順に切替え動作させる植付昇降レバー(8)と、上記操舵部材(4)による旋回の開始及び終了と連動して植付昇降レバー(8)を上昇と下降の位置に移動させる自動昇降機構(C)とを備えて構成され、上記植付部(6)の植付作業を検知する作業検知部材を設け、検知した作業が所定の継続範囲に該当しない場合に自動昇降機構(C)の作動を停止するものである。【選択図】図4
