[0026] Eight grippers 41 are used to grip eight vegetable seedlings in the same row of the seedling tray. The third drive motor 62 is started, driving the gear 64 to rotate. The moving rack 65 drives the moving frame 5 to move. During the movement of the moving frame 5, the first guide plate 51 and the second guide plate 52 move. During the movement of the second guide plate 52, different horizontal guide blocks 45 move along the corresponding horizontal rails 61, causing the four connecting plates 413 connected to the lifting plate 46 to move and drive the four gripper assemblies to move. The moving plate 42 moves with the grippers 41, and the moving block 412 located in the moving slot moves away from the fixed block 411. The eight grippers 41 are moved away from each other so that the distance between the eight grippers 41 matches the distance between the seedling cups 32 in the transfer mechanism 3. During the process of the grippers 41 moving away from each other, the first guide block moves along the first guide plate 51 and the second guide block 521 moves along the second guide plate 52 to improve stability. During the movement of the first guide plate 51, the lifting guide block 512 moves along the lifting track 43 to move the first guide plate 51 upward and the lifting block 47 moves along the lifting groove 461 to improve movement stability and facilitate the removal of vegetable seedlings from the seedling tray, thus completing the work of placing the vegetable seedlings from the seedling tray into the seedling cups 32.

[0027] The support frame 21 is equipped with a guide frame 211 that cooperates with the conveyor belt 22. The mounting plate 11 has an outlet 114 that cooperates with the output end of the guide frame 211. The mounting plate 11 is inclinedly equipped with a sliding plate 14 located below the outlet 114.

The seedling tray is made of polystyrene foam, polystyrene, polyvinyl chloride, polypropylene and other materials by blow molding or injection molding process. It is deformable. After the seedling is picked up, the seedling tray part abuts against the guide frame 211 and falls onto the sliding plate 14 under the force of the guide frame 211. It then slides onto the placement rack 13 through the sliding plate 14 for easy collection by the operator.

[0028] The traveling frame 1 is equipped with a seedling planting mechanism 7, which includes a first rotating shaft 71 and a connecting plate 72 coaxially and fixedly connected to the first rotating shaft 71. The first rotating shaft 71 is rotatably connected to the traveling frame 1. Several hanging cups 73 are equidistantly arranged on the connecting plate 72 along its circumference. The traveling frame 1 is equipped with a mounting plate 11 located above the seedling planting mechanism 7. The mounting plate 11 has an inlet 113 located above the seedling planting mechanism 7, into which vegetable seedlings are placed. The seedling cup 32 is positioned along its circumference. As the transfer belt 31 moves, when the seedling cup 32 containing vegetable seedlings moves above the delivery port 113, the first baffle plate 321 and the second baffle plate 322 are opened, and the vegetable seedlings fall from the seedling cup 32 into the hanging cup spout 73. During the operation of the traveling frame 1, the first rotating shaft 71 rotates continuously, and the connecting plate 72 rotates. When the hanging cup spout 73 containing vegetable seedlings moves to the lowest position, the hanging cup spout 73 opens, and the vegetable seedlings fall into the pit. Then the hanging cup spout 73 closes, completing the transplanting work.

[0029] A fixing plate 111 is fixed on the mounting plate 11, located on one side of the feeding port 113. An arc-shaped plate 112 is provided on the side wall of the fixing plate 111. A cylinder 323 that cooperates with the arc-shaped plate 112 is provided on the side wall of the first baffle plate 321. A transmission rod 324 is hinged to the side of the first baffle plate 321 and the second baffle plate 322 away from the cylinder 323. The hinge height of the transmission rod 324 with the first baffle plate 321 is lower than the hinge height with the second baffle plate 322. During the rotation of the seedling cup 32 driven by the transfer belt 31, when the seedling cup 32 passes the dispensing port 113, the fixed arc plate 112 contacts the moving cylinder 323. Under the continuous movement of the seedling cup 32, the cylinder 323 moves upward through the arc plate 112 and drives the first baffle plate 321 to move and open. Under the action of the transmission rod 324, the second baffle plate 322 opens, causing the seedling cup 32 to open and the vegetable seedlings to fall into the hanging cup spout 73, completing the automatic dispensing work. After the cylinder 323 has completely passed the arc plate 112, under the action of gravity, the cylinder 323 moves downward, driving the first baffle plate 321 and the second baffle plate 322 to close.

[0030] The working principle of this invention is as follows: A seedling tray containing vegetable seedlings is placed on the storage rack 12 in advance. During the movement of the traveling frame 1, the first drive motor 24 is started, and the conveyor belt 22 rotates, transporting the seedling tray containing the vegetable seedlings. The third drive motor 62 is then started, moving the moving frame 5 and driving the first guide plate 51 and the second guide plate 52 to move. The seedling retrieval mechanism 4 removes the vegetable seedlings from the seedling tray, completing the process of transferring the vegetable seedlings from the seedling tray into the seedling cup 32. The seed cup 32 moves along the transfer belt 31. When the seed cup 32 containing vegetable seedlings moves above the delivery port 113, the first baffle plate 321 and the second baffle plate 322 are opened, and the vegetable seedlings fall from the seed cup 32 into the hanging cup spout 73. During the operation of the traveling frame 1, the first rotating shaft 71 rotates continuously, and the connecting plate 72 rotates. When the hanging cup spout 73 containing vegetable seedlings moves to the lowest position, the hanging cup spout 73 opens, and the vegetable seedlings fall into the pit. Then the hanging cup spout 73 closes, completing the transplanting work.
