PROBLEM TO BE SOLVED: To provide a seedling transplanter having a seedling platform structure by which a wider seedling-carrying platform region can be secured more simply than a conventional technique.SOLUTION: The wide seedling-carrying plane is obtained by arranging first, second and third spare seedling-carrying platforms 38a, 38b and 38c on the same plane by transferring the first and third spare seedling-carrying platforms 38a and 38c to the front and rear side of the second spare seedling-carrying platform 38b by turning second transfer link members 39b because the center parts of the second transfer link members 39b are supported by turning fulcrums formed at both sides of the center part of the second spare seedling-carrying platform 38b. As a result, the seedling-carrying platform having good carrying operability of seedling trays is obtained because the spare seedling-carrying platforms 38a, 38b and 38c are transferred to a state in which the spare seedling-carrying platforms 38a, 38b and 38c is arranged in the upper and lower triple-layered state, and the seedling trays are place on them respectively, or a state in which the first and the third spare seedling-carrying platforms 38a and 38c are arranged in the front and rear sides of the second spare seedling-carrying platform 38b by centering the second seedling-carrying platform 38b to afford the wide seedling tray-carrying plane by one-touch operation to provide the seedling-carrying platform having good carrying operability of the seedling trays.COPYRIGHT: (C)2011,JPO&INPIT【課題】従来技術より、さらに簡単に、しかも広い苗載置台領域を確保できる苗台構成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されるに分けて苗トレイを載置する状態と第2予備苗載台38bを中心とし、その前後に第1予備苗載台38aと第3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るので、苗トレイの載置作業性が良い苗載台が得られる。【選択図】図3
