Self-propelled full-automatic densely-planting vegetable transplanter and planting control method thereof

A self-propelled full-automatic densely planted vegetable transplanter, comprising a seedling pick-up and delivery mechanism (1), a box transfer device (4), a caterpillar-track-type travelling chassis (10), a seedling guide device (13), a soil covering mechanism (14), a planting mechanism (16) and a dispersing device (17), wherein the box transfer device (4) is mounted on the caterpillar-track-type travelling chassis (10); the dispersing device (17) is located on one side of the box transfer device (4); the seedling pick-up and delivery mechanism (1) comprises a seedling pick-up and delivery motion mechanism (1-2) and a linear movement mechanism; the linear movement mechanism is arranged above the box transfer device (4), and the seedling pick-up and delivery motion mechanism (1-2) reciprocatingly moves between the dispersing device (17) and the box transfer device (4) by means of the linear movement mechanism; the dispersing device (17) is connected to the seedling guide device (13), and the planting mechanism (16) is located at the bottom of the seedling guide device (13); and the soil covering mechanism (14) is mounted on the caterpillar-track-type travelling chassis (10), and is located behind the planting mechanism (16). The transplanter effectively solves the existing problems of seedling leaf damage and seedling entrainment caused by seedling pick-up jaws picking up seedlings by being inserted from right above the seedlings. Thus, the transplanter reduces damage to seedling pots, ensures the integrity of the seedling pots, and improves the success rate of seedling pick-up. A planting control method for the transplanter is further involved.
