PROBLEM TO BE SOLVED: To provide a seedling planting device suppressing its vibration and stably planting seedlings, wherein a rotation case is equipped on a driving shaft horizontally pivoted on a driving case of a rice transplanter, while planting shafts parallel with the driving shaft are freely rotatably set on the rotation case and on at least two equally divided positions on the circumference around the driving shaft as its center, seedling planting bodies are attached on each planting shaft with a posture of directing divided claws set at the tip ends, in the direction to the seedling table on the side view, and an interlocking mechanism making each planting shaft rotate in the reverse direction by one turn during one revolution of the driving shaft in the rotation case, is set on the rotation case, and each seedling planting body is formed to be vertically rotatable around the driving shaft with the posture directing the divided claws in the direction of the seedling table.SOLUTION: Balancing weights 26 are set on each planting body 20 to project beyond a planting shaft 19 of the center of the rotation of the planting body to the reverse side against a seedling table 12.COPYRIGHT: (C)2009,JPO&INPIT【課題】田植機における伝動ケースに横向きに軸支した駆動軸に回転ケースを装着し,この回転ケースには前記駆動軸を中心とする円周上の少なくとも等分二箇所に,前記駆動軸と平行の植付け軸を回転自在に設け,この各植付け軸に,苗植付け体を,先端に設けた分割爪を側面視で苗載台の方向に向けた姿勢にして装着する一方,前記回転ケースに,当該回転ケースにおける前記駆動軸による一回の公転中に前記各植付け軸が逆方向に一回だけ自転するようにした連動機構を設けて,前記各苗植付け体を,その分割爪が苗載台の方向を向いた姿勢のままで前記駆動軸を中心にして上下方向に旋回するように構成して成る苗植付け装置において,その振動を抑制し,安定した苗の植付けを行う。【解決手段】前記各苗植付け体20に,バランスウエイト26を,当該苗植付け体における自転の中心である植付け軸19よりも苗載台12と反対側に突出するように設ける。【選択図】図3
