PROBLEM TO BE SOLVED: To provide a seedling transplanter in which while alleviating labor and burden of an operator when changing a reserve seedling stand to a developed state and a housed state, work efficiency is improved.SOLUTION: The seedling transplanter includes: two or more reserve seedling stands 38 supported by a supporting frame 49 of a traveling vehicle body 2 a link mechanism K between the reserve seedling stand 38 and the supporting frame 49 a cylinder 81 connected with the supporting frame 49 a moving member 83 which moves to a cross direction by an operation of the cylinder 81 and a rotary member 84 which rotates contacting with the moving member 83 and is connected with the link mechanism K, wherein a changing device 50 which changes the reserve seedling stand 38 to a developed state and a housed state, a switch 70 of the changing device 50, a sensor 72 of the switch 70, and a controller 100 which operates the cylinder 81 according to an operation of the changing switch 70 are formed. Since an operator can automatically change the reserve seedling stand 38 by an operation of the switch 70, labor and burden of the operator are alleviated, and work efficiency is improved.COPYRIGHT: (C)2012,JPO&INPIT【課題】予備苗載せ台を展開状態と収納状態とに切り替える際の作業者の労力や負担を軽減すると共に、作業能率が向上する苗移植機の提供である。【解決手段】走行車体2の支持フレーム49に支持される複数の予備苗載せ台38と、予備苗載せ台38と支持フレーム49との間のリンク機構Kと、支持フレーム49に連結するシリンダ81と、シリンダ81の作動により前後方向に移動する移動部材83と、移動部材83に接触して回転し、リンク機構Kに連結する回転部材84とを備え、予備苗載せ台38を展開状態と収納状態とに切り替える切替装置50と、切替装置50の切替スイッチ70と、スイッチ70のセンサ72と、切替スイッチ70操作に応じてシリンダ81を作動する制御装置100とを設けた苗移植機である。作業者がスイッチ70操作によって予備苗載せ台38を自動的に切り替えられるので、作業者の労力や負担を軽減し、作業能率が向上する。【選択図】図6
