PROBLEM TO BE SOLVED: To provide a seedling transplanter which is prevented in deformation caused by a load by being energized at its right and left parts and its center by a spring, and can normally perform up-and-down motion even if up-and-down slide mechanisms are deteriorated due to age.SOLUTION: In the seedling transplanter, a ground leveling device 27 for leveling the face of a plow land is arranged at the lower part of a seeding planting part 4, the fore-and-aft slide mechanisms S1, S2 for vertically moving the ground leveling device 27 are arranged, draw-up members 77, 77 for vertically energizing right and left both sides of the ground leveling device 27 are arranged, connecting support members 84, 84 protruding toward the front side of a machine body are arranged at the ground leveling device 27, the front-side slide mechanism S2 is arranged at the connecting support members 84, 84, the rear-side slide mechanism S1, S1 are arranged at the rear-side upper part and right and left sides of the ground leveling device 27, and a hoisting member 120 is arranged at the front side rather than the front-side slide mechanism S2.COPYRIGHT: (C)2013,JPO&INPIT【課題】左右及び中央部をスプリングで付勢し、荷重による変形を防止すると共に、上下スライド機構が経年劣化しても正常に上下動を行うことのできる苗移植機を提供する。【解決手段】苗植付部4の下部に圃場面を均す整地装置27を設け、整地装置27を上下動させる前後の摺動機構S1,S2を設け、整地装置27の左右両側を上方に付勢する引上部材77,77を設け、整地装置27に機体前側に突出する連結支持部材84,84を設け、連結支持部材84,84に前側摺動機構S2を設け、整地装置27の後側上部で且つ左右両側に後側摺動機構S1,S1を設け、前側摺動機構S2よりも前側に持上部材120を設ける構成とする。【選択図】図9
