PROBLEM TO BE SOLVED: To provide a seedling transplanting machine with a leveling unit in which a ground height of a float is stabilized even if the change of irregularities during planting work of seedlings and the change of hardness and softness of soil are present, and the seedlings are not washed away due to the occurrence of a mud flow and a water flow by the float.SOLUTION: A seedling transplanting machine is configured by: liftably providing a seedling planting unit 8 for planting the loaded seedlings in a field at the rear side of a traveling vehicle body 3 a leveling rotor 9 for leveling a field surface at the front side lower part of the seedling planting unit 8 providing a float 10 gliding on the field surface at the front side of the leveling rotor 9 and leveling the field surface providing a planting lifting/lowering mechanism for controlling a depth of the seedling planting unit 8 in conformity to irregularities of the field detected by the float 10 and leveling the field surface where the seedling planting unit 8 plants the seedlings by the leveling rotor 9 with a rotor shaft 11 provided in series over the lateral direction.COPYRIGHT: (C)2015,JPO&INPIT【課題】苗の植付作業中の凹凸の変化や、土質の硬軟の変化があっても、フロートの接地高さを安定させると共に、フロートが泥流や水流を発生させて苗を押し流すことのない整地装置を備える苗移植機を提供する。【解決手段】走行車体3の後側部に、積載した苗を圃場に植え付ける苗植付部8を昇降自在に設け、苗植付部8の前側下部に、圃場面を整地する整地ロータ9を設けると共に、整地ロータ9の前側の圃場面を滑走して整地するフロート10を設け、フロート10が検出した圃場の凹凸に合わせて苗植付部8の植付深さを制御する植付昇降機構を設けると共に、ロータ軸11を横方向に亘って一連に設ける整地ロータ9で、苗植付部8が苗を植え付ける圃場面を整地する構成とする。【選択図】 図3
