PROBLEM TO BE SOLVED: To provide a seedling transplanter having a seedling platform by which a wide seedling-carrying platform region can be secured more simply than conventional techniques.SOLUTION: A wide seedling box-carrying plane is obtained by arranging first, second and third spare seedling-carrying platforms 38a, 38b and 38c on the almost same plane in a connected state by transferring the first and third spare seedling-carrying platforms 38a and 38c to the front and rear of the second spare seedling-carrying platform 38b by turning second transfer link members 39b because the second transfer link members 39b are supported at the center parts thereof by turning fulcrums formed at both sides of the center part of the second spare seedling-carrying platform 38b wherein a state in which the seedling trays are carried by arranging respective spare seedling-carrying platforms 38a, 38b and 38c to be in the upper and lower triple-layered state as a whole, and a state obtaining a wide seedling tray-carrying plane on which the movable type first and third spare seedling-carrying platforms 38a and 38c are arranged at the front and the rear of the fixed type second spare seedling-carrying platform 38b to center the second seedling-carrying platform 38b are switched by a single action, thus obtaining the spare seedling-carrying platform having good carrying operability of seedling trays.COPYRIGHT: (C)2011,JPO&INPIT【課題】従来技術よりさらに簡単に、広い苗載置台領域を確保できる苗載台を備えた苗移植機を提供すること。【解決手段】第2移動リンク部材39bは、その中央部が第2の予備苗載台38bの中央部の両側に設けられた回動支点により支持されているので、第2移動リンク部材39bを回動させて、第1、第3予備苗載台38a,38cを第2予備苗載台38bの前後に移動させて、第1、第2、第3予備苗載台38a,38b,38cを接続状態でほぼ同一平面上に配置することで広い苗箱載置平面が得られ、個々の予備苗載台38a,38b,38cを全体として上下三段に配置して苗トレイを載置する状態と固定式の第2の予備苗載台38bを中心としてその前後に可動式の第1の予備苗載台38aと第3の予備苗載台38cが配置された広い苗トレイ載置平面が得られる状態にワンタッチで配置替えすることができ、苗トレイの載置作業性が良い予備苗載台が得られる。【選択図】図7
