The onion seedlings are placed on the conveying surface of the conveyor belt 3 one by one through the upper seedling window, and the onion seedlings are arranged linearly along the conveying direction of the conveyor belt 3. Since the output end of the conveyor belt 3 corresponds to the input end of the adjacent conveyor belt 3 below, the onion seedlings on the upper conveyor belt 3 can be transported to the conveyor belt 3 below in sequence, and finally the onion seedlings are transported from the lower seedling port 4 to the seedling separation mechanism through the lower conveyor belt 3. The seedling separation mechanism is arranged below the lower seedling port 4, and the seedling separation mechanism includes a seedling separation cylinder 5, which is rotatably mounted on the frame 1, and the side wall of the seedling separation cylinder 5 is provided with a plurality of The seedling separation groove 6 is evenly distributed along the circumferential direction of the seedling separation tube 5, and the seedling separation groove 6 can only accommodate one onion seedling. The seedling picking and planting mechanism is arranged in the lower seedling range of the seedling separation tube 5. The seedling picking and planting mechanism includes a lower seedling long arm 7 and a lower seedling track 8. The lower seedling long arm 7 is rotatably installed, and one end of the lower seedling long arm 7 is fixed with a lower seedling track 8. The lower seedling track 8 is used to receive the onion seedlings lowered by the seedling separation tube 5. The soil drilling mechanism includes a lifting arm 9 and a drill bit 10. The bottom wall of the lifting arm 9 is fixed with a mounting plate 11. The drill bit 10 is rotatably arranged at the bottom of the mounting plate 11.

The lifting arm 9 moves back and forth, and cooperates with the walking of the transplanter to drill planting pits at equal intervals in the field, and the onion seedlings are transported to the seedling separation tube 5 in turn through the seedling storage and transporting mechanism. The gap between the seedling separation tube 5 and the bottom surface of the seedling storage box 2 is smaller than the size of the onion seedlings, so that the onion seedlings that do not fall into the seedling separation groove 6 will not fall out of the seedling separation tube 5. Since the seedling separation groove 6 can only accommodate one onion seedling,The extra onion seedlings are left on the seedling separation tube 5, waiting for the next seedling separation groove 6 to rotate to the seedling lowering mouth 4, and the extra onion seedlings fall into the next seedling separation groove 6, and the seedling separation tube 5 rotates close to the seedling lowering track 8. When the seedling separation groove 6 accommodating the onion seedlings corresponds to the seedling lowering track 8, at this time, the seedling separation groove 6 is in an inclined state, so that the onion seedlings in it fall on the seedling lowering track 8, and then the seedling lowering long arm 7 deflects, so that the seedling lowering track 8 deflects into an inclined state, so that the onion seedlings on the seedling lowering track 8 slide into the planting pit, and with the movement of the transplanter, one onion seedling is transplanted in each planting pit, and when the transplanter moves During the process, the soil covering mechanism at the rear of the frame 1 covers the planting pit with soil, and the height of the soil covering plate 14 can be adjusted by the up and down movement of the lifting column 13, and then the soil is gathered and pushed into the planting pit by the two soil covering plates 14, thereby realizing the soil covering operation. A watering and fertilizing box is arranged at the rear of the frame 1, and a watering nozzle is arranged at the bottom of the watering and fertilizing box, so that the planting pit is watered and fertilized after the soil covering is completed, so that the transplanter integrates drilling, onion seedling transportation, onion seedling planting, soil covering, watering and fertilizing, realizes the automatic transplanting of onion seedlings, improves the planting efficiency of onion seedlings, and reduces labor costs.

Under normal circumstances, the lower seedling long arm 7 is in a vertical state, and the lower seedling track 8 is in a horizontal state, so that the onion seedlings on the seedling separation tube 5 can accurately fall on the lower seedling track 8, and then under the deflection of the crank 32, the lower seedling long arm 7 drives the driven seedling taking shaft 30 to deflect, so that the lower seedling long arm 7 is deflected close to the lower seedling channel 36, and the lower seedling track 8 is tilted toward the lower seedling channel 36, so that the onion seedlings in the lower seedling track 8 fall into the lower seedling channel 36. The lower seedling channel 36 is hollow, and the opening gradually decreases from top to bottom, so as to guide the onion seedlings, so that the onion seedlings fall accurately into the planting pit, and the automatic transplanting of the onion seedlings is realized. The stepper motor 31 drives the driving spindle 29 to deflect back and forth, so that the seedling taking and planting mechanism repeats the above action to complete the planting of the onion seedlings.

After falling on the seedling lowering track 8, the steering gear 37 rotates, and the steering gear 37 drives the steering gear piece 38 to rotate. The arc connecting rod 39, the steering gear piece 38 and the clamping claw 40 form a crank connecting rod mechanism, so that the steering gear piece 38 drives the clamping claw 40 to slide on the clamping seat 41 through the arc connecting rod 39. Since the two clamping claws 40 are symmetrically arranged, the moving directions of the two clamping claws 40 are opposite. When the onion seedlings fall on the seedling lowering track 8, the two clamping claws 40 move close to the onion seedlings to complete the clamping of the onion seedlings, so that the onion seedlings are stabilized on the seedling lowering track 8. When the seedling lowering long arm 7 is deflected to a specified position, the steering gear 37 is reversed to move the clamping claw 40 to move the onion seedlings, thereby loosening the onion seedlings, allowing the onion seedlings to slide into the seedling lowering channel 36 under their own gravity, thereby achieving accurate seedling lowering of the onion seedlings.
