The utility model discloses a non - circle - elliptic gear planetary gear train seedling transplanting mechanism of double row star posture. The seedling can only be got with direct mode of pressing from both sides the seedling with the integrative seedling transplanting mechanism that plants to the present seedling of getting, has the damage to the shoot root, get the seedling and realize then relatively complicacy with planting through two sets of mechanisms. The utility model discloses a drive sprocket axle and center pin pass through the bearing supporting at power drive case both ends, the rigid coupling passes through chain with the rigid coupling at the epaxial central sprocket in center at the epaxial drive sprocket of drive sprocket and is connected, the both ends symmetry of center pin is equipped with two main planetary gear train, goes up vice planetary gear train and sets up respectively at main planetary gear train both ends with lower vice planetary gear train, going up vice planetary gear train and being equipped with the arm of planting, lower vice planetary gear train is equipped with down the arm of planting. The utility model discloses use the one set of mechanism to realize the alms bowl formula of fetching earth and get the seedling, be in the translation getting seedling stage seedling claw, can keep alms bowl soil integrality, it is far away apart from the centre of turning circle of mechanism to push away seedling section orbit, improves the operational environment of mechanism.
