PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of performing its proper posture control by a simple constitution.SOLUTION: This seedling transplanter is provided by installing left and right compactors 4 for compacting each of left and right seedling transplanting positions performed by left and right seedling-transplanting hoppers 3 by actuating a lifting up and down actuator 15 by a lifting up and down sensor 5 for detecting the height of a field relative to its machine body by making a contact with the surface of the field, installing left and right sensor arms 47 moving jointly with each of the up and down movements of the left and right compactors 4 by taking an interval, installing a vehicle body posture-controlling device for actuating a rolling actuator 17 by detecting the inclination of the machine body with the interval change of the left and right sensor arms 47, and also keeping a lifting up and down sensor 5 arranged at the left and right reverse sides of the machine body toward one side wheel 10 of which height is changed by the rolling actuator 17.COPYRIGHT: (C)2010,JPO&INPIT【課題】簡潔な構成で適正な機体の姿勢制御が行える苗植機を得ることを課題とする。【解決手段】圃場面に接地して機体に対する圃場の高さを検出する昇降センサ5にて昇降アクチュエータ15を作動させ、左右苗植付ホッパー3による左右の各苗植付位置を鎮圧する左右鎮圧具4を設け、該左右鎮圧具4の上下動と各々連携して作動する左右センサーアーム47を間隔を開けて設け、該左右センサーアーム47の間隔変動にて機体の傾きを検出してローリングアクチュエータ17を作動させる車体姿勢制御装置を設けると共に、ローリングアクチュエータ17にて高さ変更される片側の車輪10に対して機体の左右方向反対側に昇降センサ5を配置した苗植機。【選択図】図1
