PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of easily adjusting the amount of seedlings taken from a seedling placing table by a planting device, and capable of sufficiently securing the planting depth of the planting device.SOLUTION: In the seedling transplanter, seedlings are taken from a seedling mat of the seedling placing table 39 of the seedling planting device 3 by a plurality of planting bodies 176 with the rotation of a planting driving mechanism which rotates within a planting drive case 171 with the driving force received from a power transmission mechanism 40 to which the driving force of a travelling vehicle 1 is transmitted. In this seedling planting operation of the seedling transplanter, the amount of seedlings to be taken by the planting bodies 176 is increased or decreased or the planting depth of each planting body 176 is changed by the operation of a switching device 123 which changes the rotation trajectory of the planting body 176 around a rotating axis 174 by switching the power transmission mechanism 40.COPYRIGHT: (C)2012,JPO&INPIT【課題】植付装置による苗載せ台からの苗取り量の調節が容易であり、また植付装置の植付深さを十分に確保できる苗移植機を提供すること。【解決手段】走行車両1の駆動力が伝達される伝動機構40からの駆動力を受けて植付駆動ケース171内で回転する植付駆動機構の回転によって苗植付装置3の苗載せ台39の苗マットから苗を複数の植付体176で取って圃場に植え付ける苗植付動作をするとき、伝動機構40を切り替え可能して植付体176の回転軸174周りの回転軌跡を変更する切替装置123の操作により植付体176の苗取り量を増減させるか、又は植付体176の植付深さの深浅を変更する構成とした苗移植機である。【選択図】図4
