PROBLEM TO BE SOLVED: To provide a seedling transplanter with a plurality of spare seedling loading tables, capable of easily loading or unloading seedlings on the spare seedling loading tables and having a greater capability of storing the seedling transplanter in a warehouse, etc. than a conventional seedling transplanter.SOLUTION: A tubular lifting support 80 is inserted into an apex of a support machine frame 49a from above in such a way as slidable in the vertical direction. One end of a rotating shaft 70a1 of a gear 70a of a switch driving device 70 is rotatably attached to a rotation fulcrum 39b3 of a moving link member 39b on a middle stage of a working state switching mechanism A, and the other end of the rotating shaft 70a1 is rotatably supported to a sidewall of the tubular lifting support 80. An arm 81 of sequentially connected three-stage link arms 81, 82 and 83 is attached to the support machine frame 49a, and a proximal side end of the arm 83 is fixed to the rotating shaft 70a1. A select pin 85 for selecting and driving one of a link driving arm 91 for rotating the moving link member 39b whose base is fixed to the rotation fulcrum 39b3 or the upper stage link arm 83 for lifting the lifting support 80 is provided in the gear 70a.COPYRIGHT: (C)2013,JPO&INPIT【課題】予備苗載せ台への苗の積み込みや取り出しが容易であり、苗移植機の倉庫などへの収納性を従来より高めた複数の予備苗載せ台を有する苗移植機を提供すること。【解決手段】支持機枠49aの頂部に筒状の昇降支柱80を上方から上下摺動自在に挿入し、作業状態切替機構Aの中段の移動リンク部材39bの回動支点39b3に回動自在に切替駆動装置70のギヤ70aの回動軸70a1の一端部を装着し、回動軸70a1の他端部を筒状の昇降支柱80の側壁に回動自在に支持させ、順次連結される3段リンクアーム81、82、83のアーム81を支持機枠49aに取り付け、アーム83の基部側端部を回動軸70a1に固着し、回動支点39b3に基部を固着した移動リンク部材39bの回動用のリンク駆動アーム91と昇降支柱80昇降用の上段リンクアーム83のいずれか一方を選択して駆動させるセレクトピン85をギヤ70aに設けた。【選択図】図8
