PROBLEM TO BE SOLVED: To provide a seedling transplanter which can more easily perform a seedling-supplying work into the seedling-supplying cup 41 of a seedling-supplying device of a moving mechanism, while taking out the seedling from a seedling tray.SOLUTION: There is provided the seedling transplanter in which a seedling-planting device 4 having a seedling planting member 4a for receiving a seedling from a seedling-supplying device 40 in a delivering portion R below the seedling-supplying device 40 disposed on a travel device 1 and then planting the seedling in a field in an upward or downward moving process in a prescribed movement locus T is disposed, characterized by disposing movable auxiliary seedling-supplying devices 43, 43 above the seedling-supplying device 40 except the seedling-delivering portion R from the seedling-supplying device 40 to the seedling planting member 4a. Thereby, the supply of seedlings from the auxiliary seedling-supplying devices 43, 43 to the seedling-supplying device 40 is facilitated.COPYRIGHT: (C)2010,JPO&INPIT【課題】苗載置台から苗を取り出しながら移動機構の苗供給装置の苗供給カップ41への苗の供給作業を従来に比べて容易に行うことができる苗移植機を提供することである。【解決手段】走行装置1上に配置した苗供給装置40の下方に苗供給装置40からの苗を受渡し部Rで受け取り、所定の作動軌跡Tにより上下動する過程で圃場に苗を植え付けるための苗植付体4aを有する苗植付装置4を設け、更に移動式の補助苗供給装置43、43’を苗供給装置40から苗植付体4aへの苗の受渡し部R以外の苗供給装置40の上方に設けた苗移植機であり、補助苗供給装置43、43’から苗供給装置40への苗の補給が容易となる。【選択図】図1
