[0002] In sweet potato cultivation, insect-borne viruses can cause sweet potatoes to carry viruses, leading to reduced yields. Therefore, sweet potato detoxification is carried out to remove the viruses from the sweet potatoes and restore their natural growth characteristics. During the detoxification process, a cultivation device is generally used to plant and cultivate the original seed potatoes until sweet potato seedlings grow, which are then called virus-free sweet potato seedlings and can be directly used for field production.

[0003] Existing Chinese patent CN 218337267 U discloses a cultivation rack for virus-free sweet potato seedlings. This rack, equipped with a water storage tank, can centrally collect water discharged from irrigating the seedlings, effectively reducing water loss, improving water resource utilization, reducing waste, and saving unnecessary costs. Through the cooperation of a drive rod and a slide rail, the circular motion of the drive rod drives the frame to move horizontally and linearly within the slide groove, causing multiple spray heads to move evenly above the hollow horizontal plate, ensuring each seedling is sprayed. However, during water collection and recycling, the water often contains soil. The aforementioned cultivation rack lacks a filtration structure, causing soil to flow into the water storage tank, accumulating and becoming difficult to clean. This reduces the water collection space within the tank, hindering effective water collection and recycling. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-7 As shown, a sweet potato seedling cultivation device includes a support 1, two side plates 2 fixed on the support 1, and multiple cultivation trays 3 installed between the two side plates 2. The bottom of each cultivation tray 3 is provided with a collection frame 4, and each collection frame 4 is provided with a drawer-type filter element. A water tank 6 is installed at the bottom of the support 1. One of the side plates 2 is provided with a movable spray element, and the two side plates 2 are also provided with a return assembly that discharges the water filtered by the filter element in the collection frame 4 into the water tank 6.

[0030] The filter element includes a filter plate 5 with a filter screen in the middle. A cover plate is installed at one end of the filter plate 5, and a sealing ring is provided on the inner side of the cover plate. A port for inserting and removing the filter plate 5 is opened on one side of the collection frame 4, and support bars 18 for receiving the filter plate 5 are installed on both sides of the inner wall of the collection frame 4. The cover plate is used to block the port, and the sealing ring has the effect of sealing between the cover plate and the port to prevent water from overflowing.

[0031] Specifically, the reflux assembly includes a reflux channel 14 and an inlet channel 15 located inside the two side plates 2. Drainage outlets are provided on both sides of the collection frame 4. The inlet channel 15 is used to connect the drainage outlets with the reflux channel 14, and the end of the inlet channel 15 connected to the reflux channel 14 is inclined downward. The bottom of the two side plates 2 is connected to a reflux pipe 16 that connects to the bottom of the reflux channel 14, and one end of the reflux pipe 16 is connected to the top of the water tank 6 and communicates with the interior of the water tank 6.

[0032] Specifically, the spraying components include a spray plate 13 located above the culture tray 3, an electric push rod 8 fixed to one side of the side plate 2, and a pump body 7 installed on one side of the bracket 1. The bottom of the spray plate 13 is provided with multiple atomizing nozzles evenly distributed along its length. The telescopic end of the electric push rod 8 passes through the side plate 2 and is fixedly connected to the top of the spray plate 13. One end of the pump body 7 is connected to the water tank 6 with a pipe, and the other end is connected to a water supply pipe 9. A connecting hose 10 is connected between the water supply pipe 9 and the spray plate 13.

[0033] As described above, when cultivating sweet potato seedlings, the sweet potato seedlings are first planted on the cultivation tray 3 for cultivation. When watering is needed, the spray plate 13 can be moved above the cultivation tray 3 by the electric push rod 8. At the same time, the water stored in the water tank 6 is drawn out by the pump body 7 and transported into the spray plate 13 through the water delivery pipe 9 and the connecting hose 10. Then, the water is sprayed out by the atomizing nozzle at the bottom of the spray plate 13 to irrigate the sweet potato seedlings.

[0034] During irrigation, excess water in the cultivation tray 3 is drained into the collection frame 4 through the holes at its bottom. At this time, the filter plate 5 filters the water through the filter screen. The filtered water is then drained into the return water channel 14 through the drain outlets on both sides of the collection frame 4 and the water inlet channel 15, and falls down along the return water channel 14. Finally, it is discharged into the water tank 6 through the return pipe 16, thus realizing the recycling of water. This not only enables the timely discharge of excess water in the cultivation tray 3, preventing root rot in sweet potato seedlings and ensuring the normal growth of sweet potato seedlings, but also facilitates the recycling of water, achieving the effect of saving water resources and avoiding waste.

[0035] Furthermore, to facilitate the rapid discharge of water collected in collection box 4, such as... Figure 4 and Figure 5 As shown, the inside of the collection frame 4 is also provided with a diversion plate 17 with a triangular cross section, and the two inclined surfaces of the diversion plate 17 are inclined toward the drain outlets on both sides of the collection frame 4 respectively.

[0036] Furthermore, to facilitate the stable insertion and removal of the filter plate 5, such as Figure 4 , Figure 5 and Figure 8 As shown, a slide rail is installed on the support bar 18, and a slide rail groove that matches the slide rail is opened at the bottom of the filter plate 5.

[0037] Furthermore, such as Figures 1-3 As shown, a limiting rod 12 is also installed between the two side plates 2, and a limiting block 11 is fixed on the top of the spray plate 13, and the limiting block 11 is slidably sleeved on the limiting rod 12.

[0038] When the electric push rod 8 drives the spray plate 13 to move above the cultivation tray 3, the limiting block 11 slides along the limiting rod 12 to limit the cultivation tray 3, thereby ensuring the stable movement of the cultivation tray 3 and facilitating stable irrigation of the sweet potato seedlings on the cultivation tray 3.

[0039] In another embodiment, such as Figure 4 , Figure 5 as well as Figures 7-9 As shown, the filter plate 5 has two slots inside, and each slot is equipped with a spring 20. One end of each spring 20 is connected to a movable disc 21, and one side of each movable disc 21 is fixed with a positioning block 22 that can extend to the bottom of the filter plate 5. Each of the two support bars 18 has a positioning hole 19 corresponding to the positioning block 22.

[0040] When the filter plate 5 is inserted into the collection frame 4 through the opening, the filter plate 5 moves along the support bar 18. At this time, the positioning block 22 is subjected to force and squeezes the spring 20 through the movable disc 21, causing the spring 20 to contract and drive the positioning block 22 into the groove until the positioning block 22 corresponds to the positioning hole 19. At this time, the spring 20 pushes the movable disc 21 to move along the groove, causing the movable disc 21 to push out the positioning block 22 and lock it into the positioning hole 19, so as to position the filter plate 5 and the support bar 18, thus completing the installation of the filter plate 5 and realizing the quick positioning of the filter plate 5 for quick installation. Conversely, when the filter plate 5 is pulled out from the opening, the positioning block 22 will be subjected to force and squeeze the spring 20 through the movable disc 21, causing the spring 20 to contract and drive the positioning block 22 into the groove. Then the filter plate 5 moves along the support bar 18 until it is taken out from the collection frame 4, completing the disassembly of the filter plate 5 and realizing the cleaning or replacement of the filter plate 5.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
