1. A self-propelled full-automatic dense-planting vegetable transplanter, comprising a seedling taking and throwing mechanism, a box moving device, a crawler-type walking chassis, a seedling guiding device, a soil covering mechanism, a planting mechanism, and a dispersing device, wherein
the box moving device is mounted on the crawler-type walking chassis to feed a plug tray; the dispersing device is located on one side of the box moving device; the seedling taking and throwing mechanism comprises a seedling taking and throwing movement mechanism and a linear movement mechanism; the linear movement mechanism is arranged above the box moving device, and the seedling taking and throwing movement mechanism is configured to reciprocate between the dispersing device and the box moving device through the linear movement mechanism; the dispersing device is connected to the seedling guiding device, and the planting mechanism is located at a bottom of the seedling guiding device and is configured to transplant plug seedlings; the soil covering mechanism is mounted on the crawler-type walking chassis, and the soil covering mechanism is located behind the planting mechanism to cover soil on plug seedlings that are planted;
the seedling taking and throwing movement mechanism comprises a forward-backward movable fixing plate, a seedling taking and throwing movement component, a seedling taking needle movement component, a lead screw motor, and a seedling taking needle movement cylinder; a top of the forward-backward movable fixing plate is connected to the linear movement mechanism through a first sliding pair; the forward-backward movable fixing plate is connected to the seedling taking and throwing movement component through a second sliding pair, the lead screw motor is mounted on the forward-backward movable fixing plate, and a push rod of the lead screw motor is connected to the seedling taking and throwing movement component to drive the seedling taking and throwing movement component to move vertically; the seedling taking and throwing movement component is connected to the seedling taking needle movement component through a third sliding pair, the seedling taking needle movement cylinder is mounted on the seedling taking and throwing movement component, and a piston rod of the seedling taking needle movement cylinder is connected to the seedling taking needle movement component to drive the seedling taking needle movement component to move vertically;
the seedling taking and throwing movement component comprises a seedling taking and throwing movement plate, seedling pushing ring connecting plates, and seedling pushing rings; a first guide rail is mounted on one side surface of the seedling taking and throwing movement plate, a first slide block is mounted on the forward-backward movable fixing plate, and the first slide block is movably mounted on the first guide rail; the one side surface of the seedling taking and throwing movement plate is connected to the push rod of the lead screw motor; the seedling taking needle movement cylinder is mounted on an other side surface of the seedling taking and throwing movement plate; a plurality of the seedling pushing ring connecting plates are mounted at a bottom of the other side surface of the seedling taking and throwing movement plate, and the seedling pushing rings are respectively mounted on the seedling pushing ring connecting plates;
the seedling taking needle movement component comprises a seedling taking needle movement pressing plate, fixing plate connecting plates, seedling taking needle fixing plates, and seedling taking needles; a second slide block is mounted on one side surface of the seedling taking needle movement pressing plate, a second guide rail is mounted on the other side surface of the seedling taking and throwing movement plate, and the second slide block is movably mounted on the second guide rail; the one side surface of the seedling taking needle movement pressing plate is connected to the piston rod of the seedling taking needle movement cylinder; a plurality of the fixing plate connecting plates are arranged at a bottom of an other side surface of the seedling taking needle movement pressing plate, and the fixing plate connecting plates correspond one-to-one to the seedling pushing ring connecting plates; and two sides of the fixing plate connecting plates are respectively connected to the seedling taking needles through the seedling taking needle fixing plates.
