The device includes two symmetrically arranged brackets 1, between which a plurality of water tanks 2 that can be moved up and down are slidably mounted, which can adapt to the planting of Chinese medicinal materials of different heights, a planting plate 20 with planting holes 21 is provided in the water tank 2, which can be used for soilless cultivation, and the height of the planting plate 20 can be adjusted to adjust the depth of contact between the roots of the Chinese medicinal materials and the nutrient solution. At the same time, the device also includes a separate water storage tank 3, and the water storage tank 2 is connected to the water storage tank 3 through a pipe to realize the recycling of nutrient solution. This design not only improves space utilization, but also allows plants to fully absorb nutrient solution, improving plant growth efficiency.
[0024] As a preferred feature of this embodiment, each water tank 2 is symmetrically welded with two extension plates 24 at both ends. A motorized telescopic rod 4 is fixedly mounted on the top of the upper extension plate 24, and the piston rod of the motorized telescopic rod 4 is fixedly connected to the extension plate 24 located directly above it. The design of the extension plates 24 and the motorized telescopic rod 4 allows the water tank 2 to move up and down, facilitating the cultivation of Chinese medicinal herbs at different heights.
[0025] As a preferred embodiment of the present invention, a support plate 11 is fixed to the bottom of the outer wall of the bracket 1, and the electric telescopic rod 4 at the bottom is fixed on the support plate 11. The support plate 11 provides stable support for the electric telescopic rod 4 to ensure the stability and safety of the device.
[0026] As a preferred embodiment of this embodiment, a first connecting pipe 35 connected to the downpipe 31 is installed at one end of the water reservoir 2, and a second connecting pipe 39 connected to the uppipe 34 is installed at one end of the water tank 3. A first water pump 32 is installed on the first connecting pipe 35, and a second water pump 310 is installed on the second connecting pipe 39. The design of the first connecting pipe 35, the second connecting pipe 39, and the first and second water pumps 32 and 310 enables efficient circulation of the nutrient solution between the water reservoir 2 and the water tank 3, ensuring the plants' nutrient solution needs.
[0027] As a preferred feature of this embodiment, multiple removable filters 36 are evenly spaced within the water storage tank 3, with the pore size of the filters 36 decreasing as they approach the second connecting pipe 39. These filters 36 can filter out impurities from the nutrient solution, ensuring its purity and promoting plant growth. The gradually decreasing pore size of the multiple filters 36 allows for more effective impurity filtering.
[0028] As a preferred embodiment of this embodiment, the extension plate 24 passes through the bracket 1, and the bracket 1 is provided with a strip groove 10 for the extension plate 24 to move up and down. The extension plate 24 passes through the bracket 1, and the strip groove 10 on the bracket 1 provides space for the extension plate 24 to move up and down. This design ensures both the flexibility of the water storage tank 2 and the stability of the device.
[0029] As a preferred embodiment of the present invention, the top of the screw rod 22 is higher than the top of the water storage tank 2, ensuring that the planting plate 20 can move up and down in the water storage tank 2.
[0030] As a preferred feature of this embodiment, a stirring shaft 37 is rotatably mounted within the water storage tank 3. The stirring shaft 37 passes through several filters 36 and is rotatably connected to the filters 36 via bearings. Several stirring blades 38 are mounted on the outer circumference of the stirring shaft 37. A stirring motor 33, whose output shaft is coaxially fixed to the stirring shaft 37, is mounted on the outer wall of the water storage tank 3. The design of the stirring shaft 37 and stirring blades 38 effectively prevents precipitation of components in the nutrient solution and ensures the uniformity of the nutrient solution. Furthermore, the stirring motor 33 provides power to the stirring shaft 37, enabling automatic stirring and reducing the intensity of manual operation.
[0031] When the soilless culture nutrient solution circulation device of the utility model is used:
[0032] First, the user plants Chinese herbs in the planting holes 21 of the planting plate 20. These herbs will grow through soilless cultivation. The planting plate 20 is connected to the water tank 2 via a screw 22 and an adjustment knob 23. The user can adjust the height of the planting plate 20 within the water tank 2 by rotating the adjustment knob 23, thereby controlling the contact depth between the roots of the Chinese herbs and the nutrient solution.
[0033] The water tank 2 is filled with nutrient solution, which is connected to the water tank 3 through the first connecting pipe 35 and the downpipe 31. When the user needs to provide nutrient solution for Chinese medicinal materials, the first water pump 32 will start to pump the nutrient solution in the water tank 3 into the water tank 2 for absorption by the Chinese medicinal materials.
[0034] To maintain the purity and uniformity of the nutrient solution, several filters 36 are installed within the water tank 3. These filters 36 filter out impurities in the nutrient solution. The filters 36 closer to the second connecting pipe 39 have smaller pore sizes, ensuring a purer nutrient solution entering the water tank 2. Furthermore, a stirring shaft 37 and stirring blades 38 are installed within the water tank 3. When the stirring motor 33 is activated, these shafts 37 and 38 rotate, preventing precipitation of components in the nutrient solution and ensuring uniformity.
[0035] During the growing process, users can adjust the height of the water tank 2 as needed. This is achieved via an electrically operated telescopic rod 4, the piston of which is fixedly connected to an extension plate 24 located directly above it. To adjust the height of the water tank 2, users simply extend or retract the electrically operated telescopic rod 4. This design allows the device to adapt to the needs of growing Chinese medicinal herbs at varying heights.
[0036] Finally, when the nutrient solution in water reservoir 2 needs to be refreshed or circulated, second water pump 310 is activated to pump the nutrient solution in water reservoir 2 back into water tank 3 through upper water pipe 34 and second connecting pipe 39, thus achieving nutrient solution recycling. This design not only improves the utilization rate of the nutrient solution but also ensures that the Chinese medicinal materials can continuously absorb fresh nutrient solution, thereby promoting the growth efficiency of the Chinese medicinal materials.
