PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of improving the planting efficiency and easily grasping the state of a seedling box in feeding and having excellent maintainability of the transportation path of seedling boxes.SOLUTION: The seedling transplanter is provided with a seedling holding table for holding a plurality of seedling boxes N and a seedling box transportation path 7 to switch-back the seedling box N supplied from the seedling holding table and transport to a seedling pushing apparatus 6 positioned below the table. The seedling holding table is inclined downward from the front side to the back side based on the moving direction the seedling box transportation path 7 is positioned at the back of the seedling holding table and inclined downward from the back side to the front side the seedling holding table is composed of at least two stages comprising the upper stage seedling holding table 13 and the lower stage seedling holding table 14, and the lower stage seedling holding table 14 is made to be longer than the upper stage seedling holding table 13 and extended beyond the upper stage seedling holding table 13 to a position close to the seedling box transportation path 7. The feeding speed of the seedling box is lowered at the switch-back path.COPYRIGHT: (C)2008,JPO&INPIT【課題】植付け効率の向上を図ると共に、供給中の苗箱の状態把握がし易く、また苗箱搬送径路のメンテナンス性に優れた苗移植機を提供する。【解決手段】複数の苗箱Nを載置する苗載台と、該苗載台から供給された苗箱Nをスイッチバックして下方に位置する苗押出装置6まで搬送する苗箱搬送路7を備え、前記苗載台は進行方向の前方側から後方に向けて下方傾斜する一方、前記苗箱搬送路7は前記苗載台の後方に位置すると共に後方側から前方に向けて下方傾斜し、かつ、前記苗載台は少なくとも二段の上段苗載台13と下段苗載台14からなり、下段苗載台14を上段苗載台13よりも長尺として、上段苗載台13よりも前記苗箱搬送路7に近接する位置まで延在させている。また、スイッチバック路において苗箱の送り速度を低下させている。【選択図】図1
