[0002] Hydroponic vegetables refer to vegetables that are cultivated in a nutrient solution layer with most of their roots growing in it, and only the nutrient solution provides them with water, nutrients, and oxygen, which are different from the traditional soil cultivation form. Hydroponic vegetables have a short growth cycle and are rich in various vitamins and minerals essential for the human body.

[0003] The Chinese patent with the publication number of CN 222941446 U discloses a vegetable planting device with a flowing nutrient solution circulation supply, including a planting nutrient solution tank and three layered planting racks. A through port is integrally formed at the lower end of the inclined guide plate, and a filter solution tank is installed below the layered planting rack. A circulation pump is installed at the upper end of the filter solution tank. This patent conducts multi-layer supply work through a single-path supply pipeline. For the three layered planting racks distributed in a trapezoidal shape, the vegetables inside the lower layered planting rack can all receive light. However, during actual use, this patent can only pump the nutrient solution through the circulation pump and spray it on the upper layered planting rack and then flow and circulate. During the growth process of the plants in the lower layered planting rack, their leaves cannot be affected by the spraying effect, which easily leads to poor growth effects of the plants in the lower layered planting rack. Secondly, during the spraying process, the spraying height cannot be adjusted according to the types of plants, and the spraying effect and applicability are poor.

[0004] Therefore, it is necessary to provide a new vegetable planting device with a flowing nutrient solution circulation supply to solve the above technical problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] Please refer to Figure 1 、 Figure 2 and Figure 3 wherein, Figure 1 is a schematic structural diagram of the present utility model; Figure 2 is a schematic structural diagram of the present utility model from another angle; Figure 3 is a schematic structural diagram of the interior of the nutrient solution tank of the present utility model. It includes: nutrient solution tank 1, layered planting rack 3, adjustment mechanism and irrigation mechanism.

[0021] Refer to Figure 1 and Figure 3As shown, a liquid inlet 22 is provided on the upper surface of the nutrient solution tank 1. There are a total of three layer planting racks 3, and the three layer planting racks 3 are distributed in a trapezoidal shape above the nutrient solution tank 1. The lower surface of the layer planting rack 3 is fixedly connected to the upper surface of the nutrient solution tank 1 through a plurality of matching support rods 4. An overflow pipe 5 is fixedly connected to one side surface of each of the three layer planting racks 3. The overflow pipe 5 located at the bottommost is fixed to the upper surface of the nutrient solution tank 1. A regulating mechanism is connected to the upper surface of the nutrient solution tank 1. The regulating mechanism includes a rectangular sliding rod 7, a fixing plate 6, a sliding sleeve 8, an inverted U-shaped frame plate 10, an electric telescopic rod 11, a regulating plate 12, and a connecting rod 13. Above the nutrient solution tank 1, there are two parallel rectangular sliding rods 7. Both ends of the rectangular sliding rod 7 are fixedly connected to a fixing plate 6. The lower end of the fixing plate 6 is fixedly connected to the upper surface of the nutrient solution tank 1. A sliding sleeve 8 is slidably sleeved on the rectangular sliding rod 7. An inverted U-shaped frame plate 10 is fixedly connected to the two sliding sleeves 8. An electric telescopic rod 11 is installed on the upper surface of the inverted U-shaped frame plate 10. The output end of the electric telescopic rod 11 slidably penetrates through the inverted U-shaped frame plate 10 and is fixedly connected to a regulating plate 12. Two symmetrically arranged connecting rods 13 are fixedly connected to the lower surface of the regulating plate 12. An irrigation mechanism is connected to the nutrient solution tank 1, and the connecting rod 13 is connected to the irrigation mechanism.

[0022] Reference Figure 1 and Figure 2 As shown, the irrigation mechanism includes a circulation pump 15, a liquid suction pipe 16, an infusion pipe 17, a communicating pipe 18, a spray pipe 19, a hose 20, a multi-way pipe 14, and a nozzle 21. A circulation pump 15 is installed on one side surface of the nutrient solution tank 1. The inlet of the circulation pump 15 is fixedly connected to the one side surface of the nutrient solution tank 1 through the liquid suction pipe 16. The outlet of the circulation pump 15 is fixedly connected to an infusion pipe 17. The other end of the infusion pipe 17 is fixedly connected to a communicating pipe 18 and a spray pipe 19 through a three-way pipe joint. Matching control valves are installed on both the communicating pipe 18 and the spray pipe 19. The other end of the communicating pipe 18 is fixedly connected to the side surface of the topmost layer planting rack 3. The other end of the spray pipe 19 is connected to a multi-way pipe 14 through a hose 20. Three uniformly distributed nozzles 21 are installed on the lower surface of the multi-way pipe 14. The lower end of the connecting rod 13 is fixedly connected to the multi-way pipe 14.

[0023] It should be noted that during use, by sliding the sliding sleeve 8 on the rectangular sliding rod 7, the horizontal movement of the inverted U-shaped frame plate 10 can be driven. The horizontal movement of the inverted U-shaped frame plate 10 drives the horizontal movement of the electric telescopic rod 11. The horizontal movement of the electric telescopic rod 11 drives the movement of the adjusting plate 12 and the connecting rod 13. The movement of the connecting rod 13 drives the movement of the multi-pass pipe 14 and the nozzle 21, enabling the nozzle 21 to be adjusted and moved above each layered planting rack 3. After moving above the layered planting rack 3 that needs to be sprayed, the electric telescopic rod 11 is then started. The expansion and contraction of the electric telescopic rod 11 drives the vertical movement of the adjusting plate 12 and the connecting rod 13, enabling the height of the nozzle 21 to be adjusted.

[0024] It should be further noted that during use, the control valve on the connecting pipe 18 is opened. The circulating pump 15 pumps the nutrient solution in the nutrient solution tank 1 into the connecting pipe 18 through the liquid suction pipe 16 and the liquid delivery pipe 17, and then the nutrient solution is introduced into the uppermost layered planting rack 3 through the connecting pipe 18. When the height of the nutrient solution exceeds the height of the corresponding overflow pipe 5, the nutrient solution will flow into the lower nutrient solution tank 1 and finally flow into the nutrient solution tank 1 through the lowermost overflow pipe 5 for circular supply. When spraying is required, the control valve on the connecting pipe 18 is closed, and the control valve on the spray pipe 19 is opened, enabling the nutrient solution pumped out by the circulating pump 15 to be introduced into the nozzle 21 through the spray pipe 19, the flexible pipe 20, and the multi-pass pipe 14, and then sprayed onto the layered planting rack 3 by the nozzle 21 for circular supply.

[0025] Reference Figure 1 As shown in the figure, both ends of the multi-pass pipe 14 are sealed by matching pipe plugs (the pipe plugs are common existing devices and will not be elaborated here), and the pipe plugs play a sealing role for both ends of the multi-pass pipe 14.

[0026] Reference Figure 3 As shown in the figure, an oxygenation mechanism is connected to the nutrient solution tank 1. The oxygenation mechanism includes an oxygenation air pump 23, an air delivery pipe 24, and an aeration disc 25. The oxygenation air pump 23 is installed on the upper surface of the nutrient solution tank 1. The outlet of the oxygenation air pump 23 is fixedly connected to the air delivery pipe 24. The other end of the air delivery pipe 24 penetrates through the liquid inlet 22 and extends into the nutrient solution tank 1 and is installed with the aeration disc 25.

[0027] It should be noted that during use, the oxygenation air pump 23 can introduce gas into the aeration disc 25 through the air delivery pipe 24, facilitating the oxygenation of the nutrient solution in the nutrient solution tank 1 and facilitating the cultivation and use of plants.

[0028] Reference Figure 2 As shown in the figure, a matching filter screen 26 is installed in the communication hole between the nutrient solution tank 1 and the overflow pipe 5. By providing the filter screen 26, a filtering function is achieved, facilitating the use of circular supply.

[0029] Reference Figure 1As shown in the figure, locking universal wheels 2 are installed at the four corners of the lower surface of the nutrient solution tank 1. By providing the locking universal wheels 2, the flexibility of the device is improved, facilitating movement.

[0030] Reference Figure 1 As shown in the figure, a locking bolt 9 is threadedly connected to the side of one of the sliding sleeves 8. When the sliding sleeve 8 needs to slide, loosen the locking bolt 9. After the sliding sleeve 8 moves to the appropriate position, tighten the locking bolt 9 to lock the sliding sleeve 8 and prevent it from sliding during the spraying process.

[0031] The working principle provided by the present utility model is as follows: When in use, by sliding the sliding sleeve 8 on the rectangular sliding rod 7, the horizontal movement of the inverted U-shaped frame plate 10 can be driven. The horizontal movement of the inverted U-shaped frame plate 10 drives the horizontal movement of the electric telescopic rod 11. The horizontal movement of the electric telescopic rod 11 drives the movement of the adjusting plate 12 and the connecting rod 13. The movement of the connecting rod 13 drives the movement of the multi-way pipe 14 and the nozzle 21, enabling the nozzle 21 to be adjusted and moved above each layer of the planting rack 3. After moving above the layer of the planting rack 3 that needs to be sprayed, start the electric telescopic rod 11 again. The telescopic movement of the electric telescopic rod 11 drives the vertical movement of the adjusting plate 12 and the connecting rod 13, enabling the height of the nozzle 21 to be adjusted. Thus, during the use process, the plants in each layer of the planting rack 3 can be sprayed, improving the overall growth effect of the plants. Moreover, the spraying height can be adjusted according to the height of the plants, improving the spraying effect and applicability. After the adjustment is completed, open the control valve on the connecting pipe 18. The circulation pump 15 pumps the nutrient solution in the nutrient solution tank 1 into the connecting pipe 18 through the liquid suction pipe 16 and the liquid delivery pipe 17, and then the connecting pipe 18 leads it into the topmost layer of the planting rack 3. When the height of the nutrient solution exceeds the height of the corresponding overflow pipe 5, the nutrient solution will flow into the lower nutrient solution tank 1, and finally flow into the nutrient solution tank 1 through the bottommost overflow pipe 5 for cyclic supply. When spraying is required, close the control valve on the connecting pipe 18 and open the control valve on the spraying pipe 19, so that the nutrient solution pumped out by the circulation pump 15 can enter the nozzle 21 through the spraying pipe 19, the hose 20, and the multi-way pipe 14, and then be sprayed onto the planting rack 3 for cyclic supply. Thus, during the use process, spraying can be selectively carried out without continuously spraying the nutrient solution for cyclic supply, avoiding the continuous wetting of the plant leaves caused by continuous spraying, which may lead to the weakness of plant growth or even the death of the whole plant, thereby improving the plant growth effect.

[0032] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated herein.

[0033] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
