PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of preventing a float and a land-leveling rotor provided on the lower part of a seedling planting part from generating a mud water flow and hardly causing the already planted seedling to be washed away and buried in the mud.SOLUTION: A seedling transplanter includes: a seedling planting part 4 provided on a traveling vehicle body 2 so as to freely move up and down an inclination detecting member 116 provided on the seedling planting part 4 for detecting a lateral inclination a controller 100 for actuating a rolling mechanism 110 which turns the seedling planting part 4 into a horizontal attitude when the inclination detecting member 116 detects a lateral inclination and planting row determining members 34a, 101, 124, 126 for determining whether the preceding planting work row is right or left of the current planting work row. The controller 100 actuates the rolling mechanism 110 to a position to take such an inclination attitude that the side determined to be the preceding planting row by the planting row determining members 34a, 101, 124, 126 of the seedling planting part 4 is located above the other side when the rolling mechanism 110 is actuated to turn the seedling planting part 4.COPYRIGHT: (C)2014,JPO&INPIT【課題】苗植付部の下部に設けるフロートや整地ロータが泥水流を発生させず、既に植え付けられた苗が押し流されたり泥に埋もれたりしにくい苗移植機を提供する。【解決手段】走行車体2に苗植付部4を昇降自在に設け、苗植付部4に左右傾斜を検知する傾斜検知部材116を設け、傾斜検知部材116が左右傾斜を検知すると苗植付部4を水平姿勢に回動させるローリング機構110を作動させる制御装置100を設け、現在の植付作業条の左右どちら側が前回の植付作業条かを判定する植付条判定部材34a,101,124,126を設け、制御装置100は、ローリング機構110が作動して苗植付部4を回動させる際、苗植付部4のうち植付条判定部材34a,101,124,126が前回の植付条と判定した側が他側よりも上方に位置する傾斜姿勢となる位置にローリング機構110を作動させる構成とする。【選択図】図5
