[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1

[0034] See also Figure 1-6 As shown, a multi-layer seedling rack includes a bottom plate 1, a top plate 2, a bracket 10, a cross mechanism and a lifting mechanism. The surface of the bottom plate 1 is fixedly connected to a bracket 3, and the cross mechanism cooperates with the lifting mechanism to realize the lifting of the bracket 10;

[0035] The lifting mechanism includes a motor 13, which is a servo motor 13. The motor 13 is fixedly mounted on the surface of the base plate 1. The end of the output shaft of the motor 13 is fixedly connected to a threaded shaft, and the other end of the threaded shaft is rotatably connected to the bracket 3.

[0036] The bracket 10 and the top plate 2 are connected to the bracket 3 by sliding up and down through the limiting mechanism;

[0037] A fixing block 5 is fixedly connected to the surface of the top plate 2, and a threaded shaft driven by the motor 13 passes through the fixing block 5 and is threadedly connected;

[0038] The cross mechanism includes a main plate 7 and a sub-plate 6. The main plate 7 and the sub-plate 6 are cross-designed and are hingedly connected to each other.

[0039] There are multiple groups of cross mechanisms, and the ends of the main board 7 in the first group are connected to the ends of the auxiliary boards 6 in the second group by hinges, and a cross mechanism is set between the two brackets 10;

[0040] A limiting groove 20 is provided on the surface of the bracket 10. The surface of the sub-plate 6 in each group of the cross mechanism is fixedly connected to the limiting shaft 18. The surface of the main plate 7 of the first group and the last group of the cross mechanism is fixedly connected to the limiting shaft 18. The limiting shaft 18 is slidably connected in the limiting groove 20. The limiting mechanism includes a limiting rod 8, which is fixedly connected to the surface of the bracket 3. The surfaces of the top plate 2 and the bracket 10 are fixedly connected to the limiting block 11. The limiting block 11 is sleeved on the surface of the limiting rod 8 and is slidably connected.

[0041] During operation, the seedlings are placed on the bracket 10 and the motor 13 is turned on, so that the motor 13 drives the threaded shaft to rotate. At the same time, because the fixing block 5 is threadedly connected to the surface of the threaded shaft, when the threaded shaft rotates, it will drive the top plate 2 to move up and down. When the top plate 2 moves up, it will drive the cross mechanism to move, so that the main plate 7 and the sub-plate 6 rotate around the hinge. At the same time, the main plate 7 and the sub-plate 6 sliding in the limiting groove 20 on the surface of the top plate 2 will move toward each other, and then the multiple groups of cross mechanisms below will have a chain effect and move synchronously, so that multiple brackets 10 are spread out at equal distances, and the two limiting grooves 20 cooperate with the limiting shaft 18. The design can ensure that the center of gravity of the bracket 10 is always in the middle position of the bracket 10, and there will be no center of gravity offset, which avoids the problem of easy tipping and damage to the seedlings. When the bracket 10 slides up and down, it will drive the limit block 11 to slide on the surface of the limit rod 8. The limit mechanism and the symmetrically designed motor 13 can enhance the stability of the bracket 10 during placement and sliding. The liftable bracket 10 can help the seedlings better absorb sunlight and also help the staff to place and observe the seedlings more conveniently. When the seedlings grow up, the spacing can be adjusted by lifting and lowering, thereby ensuring the growth space.

[0042] A water tank 16 is fixedly connected to the surface of the bottom plate 1, and a sprinkler mechanism is provided on the surface of the bracket 10 and the surface of the top plate 2. The sprinkler mechanism includes a water pump 17. A water distribution strip 19 is fixedly connected to the surface of the bracket 10. A plurality of atomizing nozzles 14 are provided on the surface of the water distribution strip 19. The input end of the water pump 17 is connected to the water tank 16, and the output end is connected to the water distribution strip 19 through a water pipe 15. The water distribution strip 19 is approximately "S" shaped, and the water pipe 15 is a rubber hose.

[0043] During operation, when the seedlings are short of water, the water pump 17 is directly turned on to allow the water pump 17 to extract water from the water tank 16, and the water flows to the water distribution bar 19 through the water pipe 15. The multiple atomizing nozzles 14 on the surface of the water distribution bar 19 are sprayed to the seedlings at the same time to irrigate the seedlings. Because the water distribution bar 19 is approximately "S"-shaped, the irrigation range of the atomizing nozzle 14 can be increased. The seedlings can be irrigated quickly and conveniently through the sprinkler mechanism, which greatly improves the irrigation efficiency and saves manpower. At the same time, the water distribution bar 19 is set under the bracket 10 and can move with the bracket 10 at any time, thereby ensuring the irrigation effect.

[0044] The surface of the bracket 10 is provided with a water guide groove 21, and each surface of the bracket 10 is provided with a water hole 22. The water guide groove 21 is provided with an inclination angle for guiding excess water to the water hole 22. The surface of the bracket 3 is fixedly connected with a water guide shaft 4. One end of the water guide shaft 4 passes through the top plate 2 and is slidably connected to the water hole 22, and the other end passes through the water tank 16 and is fixedly connected. The water guide shaft 4 and the water tank 16 are in a non-fitting state. A water guide ring 23 with an inclined design is provided in the water hole 22, and a gap is provided between the inner diameter of the water guide ring 23 and the water guide shaft 4. When working, after the atomizing nozzle 14 is irrigated, the excess water is discharged. The water flows into the water guide groove 21 on the surface of the bracket 10. Because the water guide groove 21 is inclined, all the water guide grooves 21 point to the drain hole 22, so the excess water will pass through the drain hole 22, flow through the water guide ring 23, and finally flow into the water guide shaft 4, and flow into the water tank 16 through the water guide shaft 4. The water can be guided by the water guide shaft 4 and slowly flow into the water tank 16 to avoid cross flow and turbulence, which not only ensures the appearance, but also avoids the staff from spending time cleaning. At the same time, the bottom of the seedling pot can be ventilated through the water guide groove 21 to achieve ventilation and avoid root soaking.

[0046] See also Figure 7 As shown, in contrast to Example 1, as another embodiment of the present invention, a movable wheel 24 is provided on the surface of the base plate 1, and the movable wheel 24 is a universal wheel; when working, the seedling rack can be easily moved by the movable wheel 24, which effectively saves manpower, and the design of the universal wheel makes movement more convenient.
