Abstract
The utility model discloses a transplanting mechanism of a slippage type wide/narrow-row transplanter. A spiral slideway and a movable planting arm are installed in a traditional planting arm component, so that the planting arm carries out reverse rotation relative to a planet carrier and also carries out periodic slide in the axial direction of a planet shaft relative to a gear box. The planting arm is hollowly sleeved on an extending-out sleeve pipe which is fixedly connected with the gear box and can carry out mutual rotation and axial movement; the extending-out sleeve pipe at which the spiral slideway is arranged is fixedly connected onto the gear box by a flange and is also sleeved on the planet shaft in a sliding way; a sliding block matched with the spiral slideway is hollowly sleeved on an end cover of the planting arm, which is fixedly connected with the planting arm; and the axial motion of the planet shaft of the planting arm is driven by the axial motion of a planet shaft of the sliding block in the motion process so as to realize the periodic movement of seedling needles. The length of the extending-out sleeve pipe is shortened by the difference of the depth of the slideway so as to meet the requirement of the width between seedling doors. After seedlings are taken by the seedling needles at the seedling doors, the seedling needles are buried into the soil for transplanting the seedlings after the seedling needles are deviated at a section of distance along with the planting arm relative to the seedling doors. Therefore, the seedling transplanting positions are deviated from seedling taking ports so as to meet the requirement of wide/narrow-row seedling transplanting.
