[0019] In the above embodiment, the seedling tray recycling mechanism 4 includes a rectangular elongated hole 401 symmetrically opened on the two outer surfaces of one end of the left transfer box 101 and the right transfer box 102, and a seedling tray baffle 402 with an elongated hole corresponding to the rectangular elongated hole 401 symmetrically fixed on the two inner surfaces. The seedling tray recycling mechanism 4 includes a cylinder fixing plate 403 installed at the center position below the two rectangular elongated holes 401, a dual-axis cylinder 404 fixedly installed on the cylinder fixing plate 403, and a second seedling tray support plate 405 fixedly installed on the side of the dual-axis cylinder 404 facing the rectangular elongated hole 401.

[0020] The working principle of the above embodiments is as follows: When in use, the seedling tray 5 filled with seedlings is placed on the first seedling tray support plate 104. The triangular positioning head 107 on the first pressing plate rod 105 presses down on the seedling tray 5, which plays a role in further positioning the seedling tray 5. When the seedling tray 5 needs to move laterally, the servo motor 202 starts, driving the reducer 201 to rotate. This causes the first sprocket 203, the first transmission chain 204, and the second sprocket 205 in the left sprocket assembly, as well as the third sprocket 206, the second transmission chain 207, and the fourth sprocket 208 in the right sprocket assembly, and the transfer box drive shaft 209 and the transfer box driven shaft 210 to rotate simultaneously. This drives the two seedling pushers 212 to move laterally. The two seedling pushers 212, running under the seedling tray 5, can push the seedling tray 5 to move laterally. After the seedlings in the seedling tray are transplanted, Two push rods 212 continue to push the empty seedling tray 5 forward. At this time, the dual-axis cylinders 404 on both sides of the left and right shift boxes 101 and 102 start to operate, driving the second seedling tray support plate 405 to extend and support the moving seedling tray 5. Then, the dual-axis cylinders 404 drive the second seedling tray support plate 405 to retract, and the seedling tray 5 falls down for easy recycling. Between the two seedling tray baffles 402, a seedling tray recycling box can be placed to collect the fallen seedling tray 5, or a conveyor belt connected to other devices can be placed. The seedling tray 5 falls on the conveyor belt and is transported to other devices for recycling.

[0021] When the seedling tray 5 needs to move longitudinally, the lead screw motor 306 is started. Driven by the lead screw motor 306, the entire device moves longitudinally step by step on the corresponding guide rail 310 via two sets of sliders 309, achieving the required step distance.

[0022] In summary, this automatic transplanter seedling tray conveying device is part of the agricultural equipment seedling transplanter. The first square tube 301, the second square tube 311, and the screw motor 306 can be installed on other components of the transplanter. The transverse drive mechanism 2 controls the transverse movement of the device, and the longitudinal drive mechanism 3 controls the longitudinal movement. The longitudinal drive mechanism 3 uses a screw motor, enabling the device to move in a step-by-step manner in the longitudinal direction with more precise displacement. This helps the seedling-grabbing mechanism in the transplanter to pick up the seedlings from the seedling tray and drop them into the seedling guide tube, which then delivers them to the inside of the sowing device for planting on the collected soil. After all the seedlings in the seedling tray 5 have been transplanted, the device uses the seedling tray recycling mechanism 4 to retrieve the empty seedling tray. The device continuously cycles through the seedling trays filled with seedlings, avoiding difficulties in placing the seedling trays, reducing the number of times operators need to change the seedling trays 5, and saving time and effort, thus reducing production costs.
