[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model provides a lifting seedling cultivation rack, which includes a base 1. A bracket 4 is fixedly connected to the four ends of the base 1. The inner end of the bracket 4 is provided with a plurality of positioning grooves 6. A plurality of bearing plates 2 are slidably connected to the bracket 4. A connecting shell 5 is fixedly connected to the upper two ends of the bearing plate 2. The inner two ends of the connecting shell 5 are provided with slots 11. The positioning grooves 6 inside the bracket 4 can cooperate with the positioning blocks 8 to complete the quick fixed installation of the bearing plate 2.

[0025] A rotating shaft 13 is rotatably connected to the upper middle part of the connecting shell 5. A bevel gear 20 is fixedly connected to the lower end of the rotating shaft 13. A bidirectional screw 10 is rotatably connected to the inner end of the connecting block 5. A bevel gear 17 is fixedly connected to the middle of the bidirectional screw 10. The bevel gear 17 and the bevel gear 20 mesh with each other. Two positioning blocks 8 are threaded on the bidirectional screw 10. The other end of the positioning block 8 passes through the connecting shell 5 and corresponds to the positioning groove 6. When height adjustment is required, first rotate the rotating shaft 13 at both ends to drive the bevel gear 20 inside to rotate. Under the meshing action, the bevel gear 17 and the bidirectional screw 10 will rotate. Under the action of the threaded engagement, the positioning blocks 8 at both ends can be driven to retract inward, so that they leave the interior of the positioning groove 6, thereby adjusting the height of the entire cultivation box 3. After the adjustment is completed, rotate the rotating shaft 13 in the opposite direction so that the positioning blocks 8 re-enter the interior of the positioning groove 6 to complete the locking and fixing. This allows for adjustment of the spacing and height of multiple cultivation boxes 3, improving the applicability of the entire cultivation rack.

[0026] The inner end of the positioning block 8 is fixedly connected to the limiting plate 9. By setting the limiting plate 9, the positioning block 8 can be restricted to ensure stable movement of the positioning block 8 under the action of the thread.

[0027] An installation port is provided at the inner end of the support plate 2. Limiting grooves 12 are provided at both ends of the installation port. A cultivation box 3 is installed at the inner end of the installation port. Limiting blocks 14 are fixedly connected to both ends of the cultivation box 3. The internal threads of the limiting blocks 14 and the limiting grooves 12 are fitted with positioning bolts 7. The cooperation between the limiting blocks 14 and the limiting grooves 12 allows the staff to quickly install the cultivation box 3 on the support plate 2. The positioning bolts 7 can lock the two together and improve the strength of the connection.

[0028] The top of each of the four supports 14 has a mounting groove 18, and a mounting block 19 is installed inside the mounting groove 18. The top of the mounting block 19 is fixedly connected to the support 2 15. The mounting block 19 and the mounting groove 18 are threaded together with the positioning bolt 2 16. When the entire cultivation rack needs to be extended or adjusted, the mounting block 19 at the bottom of the support 2 15 is aligned with the mounting groove 18 at the top of the support 14, and then the positioning bolt 2 16 is used to lock it, thereby completing the extension of the cultivation rack. This is more suitable for the installation and fixing of multiple cultivation boxes 3, providing sufficient space for the growth of seedlings without interfering with their growth. Secondly, the bottom of the cultivation box 3 of this device is equipped with a guide structure, which can drain excess water through the guide structure and discharge it outward through the drain pipe connected to the rear end. Moreover, the overall size and weight of the support 2 15 are smaller than those of the support 14, avoiding the situation where the load is too high and the device tilts and falls apart. Finally, the mounting position of the positioning bolt 2 16 in the device is provided with a hole, which allows the positioning bolt 2 16 to be fully inserted without affecting the installation of the support plate 2.

[0029] Working principle: When in use, the operator first aligns the incubation box 3 with the limiting slots 12 on the support plate 2 via the limiting blocks 14 at both ends. Then, it is installed on the support plate 2 using the positioning bolts 7 to improve the stability of the incubation box 3 during use. Next, the openings at the four ends of the support plate 2 are aligned with the brackets 4 to install it on the entire incubation rack. When height adjustment is required, the rotating shafts 13 at both ends are rotated to drive the internal bevel gears 20 to rotate. Under the meshing action, the bevel gears 17 and the double-acting screw 10 are rotated. Under the action of the threaded engagement, the positioning blocks 8 at both ends are able to retract inward, causing them to leave the interior of the positioning slots 6, thereby adjusting the height of the entire incubation box 3. After the adjustment is completed, the rotating shafts 13 are rotated in the opposite direction so that the positioning blocks 8 re-enter the interior of the positioning slots 6 to complete the locking and fixing.

[0030] When it is necessary to extend and adjust the entire cultivation rack, align the mounting block 19 at the bottom of bracket 2 15 with the mounting groove 18 at the top of bracket 1 4, and then lock it with positioning bolt 2 16 to complete the extension of the cultivation rack. This is more suitable for the installation and fixing of multiple cultivation boxes 3, providing sufficient space for the growth of seedlings without interfering with their growth. It also allows for adjustment of the distance between each layer of seedlings, preventing the lower layer of seedlings from growing too fast and blocking the sunlight of the upper layer of seedlings.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
