[0031] Through the cooperation of infusion tube 33 and pump 34, the nutrient solution in liquid storage tank 3 can be stably transported to the top planting box 2, and each layer of planting box 2 is connected by using liquid outlet pipe 5, so that the nutrient solution flows down layer by layer, finally returns to liquid storage tank 3 through connecting pipe 31, forms a complete circulation path, ensures that the nutrient solution can be continuously supplied to the growth of vegetables, avoids the influence of vegetables growth due to the interruption of liquid supply, reduces the waste of nutrient solution, reduces the use cost of fertilizer, reduces the consumption of water resources, and meets the concept of green environmental protection and sustainable development.

[0032] The filter screen 24 is located above the inner cavity of the planting box 2 and is horizontally arranged at the top end of the liquid storage tank 21, which can effectively intercept impurities, plant residues and other substances in the nutrient solution. When the liquid level of the nutrient solution in the liquid storage tank 21 reaches the position of the filter screen 24, the excess nutrient solution flows into the liquid outlet tank 23 after being filtered, which can prevent impurities from entering the liquid outlet tank 23, the liquid outlet 25 and the liquid outlet pipe 5. A gap is arranged between the filter screen 24 and the planting plate 4, which can facilitate the operator to easily and quickly clean the impurities intercepted on the filter screen 24, avoid blockage, ensure the smoothness of the nutrient solution circulation channel, and maintain the stable operation of the device.

[0033] The liquid storage tank 21 is used for temporarily storing the nutrient solution, and each layer of the planting box 2 can receive relatively stable and uniform nutrient solution, which can ensure that the nutrient solution has sufficient residence time in the planting box 2, provide conditions for the root system of the vegetables to absorb nutrients, and avoid uneven supply of liquid to cause uneven growth of the vegetables.

[0034] Further, in order to conveniently clean the inside of the planting box 2, please refer to Figures 1-6 The mounting racks 22 are fixedly installed on the front and rear sides of the planting box 2, mounting holes are formed in both ends of the mounting racks 22, and the mounting racks 22 are located above the liquid storage tank 21.

[0035] The planting plate 4 is arrayed with planting holes 41, and the bottom of the planting plate 4 is provided with a positioning rod 42, which is correspondingly matched with the mounting holes in the mounting racks 22.

[0036] The rotating racks 121 are fixedly installed on both ends of the placing rack 12, the screw rods 122 are screw-connected to the rotating racks 121, and the pressing plates 123 are fixedly connected to one end of the screw rods 122 close to the planting box 2.

[0037] The liquid storage tank 3 is provided with a liquid observation tank 32.

[0038] Specifically, the mounting racks 22 on the front and rear sides of the planting box 2 are provided with mounting holes, and the positioning rod 42 at the bottom of the planting plate 4 is correspondingly matched with the mounting holes. When cleaning is needed, the planting plate 4 can be quickly disassembled by lifting it upward to make the positioning rod 42 disengage from the mounting holes of the mounting racks 22, which avoids the inconvenience of cleaning caused by the fixed connection between the planting plate 4 and the planting box 2, facilitates the cleaning of the planting holes 41 on the planting plate 4, prevents the residual plant roots and impurities from blocking the holes, and facilitates the disinfection, replacement and other operations of the planting plate 4.

[0039] By rotating the screw rod 122, the pressing plate 123 is away from the planting box 2, and the fixing of the planting box 2 is released. At this time, the planting box 2 can be easily taken out of the placing rack 12, and the operator can clean and check the components inside the planting box 2, such as the storage tank 21, the liquid outlet tank 23, and the filter screen 24, to avoid the problem of nutrient solution pollution and bacterial growth caused by incomplete cleaning. When installing, place the planting box 2 on the placing rack 12, and fix the planting box 2 through the screw rod 122 and the pressing plate 123 on the rotating frame 121 at both ends of the placing rack 12. Rotate the screw rod 122 to press the pressing plate 123 tightly against the planting box 2, and ensure the stability of the planting box 2 in the placing rack 12.

[0040] The liquid level of the nutrient solution in the storage tank 3 can be directly observed through the observation tank 32. Before cleaning the planting box 2, the operator can determine the amount of nutrient solution in the storage tank 3 through the observation tank 32, and arrange the cleaning time and operation process reasonably.

[0041] Working principle: The vegetables are planted in the planting holes 41 of the planting plate 4 of the planting box 2. By rotating the screw rod 122 on the rotating frame 121 at both ends of the placing rack 12, the pressing plate 123 is away from the planting box 2. Place the planting box 2 on the placing rack 12, and then rotate the screw rod 122 to press the pressing plate 123 tightly against the planting box 2, to ensure that the planting box 2 is firmly installed on the placing rack 12.

[0042] Start the pump 34, and the pump 34 works to transport the nutrient solution in the storage tank 3 to the inlet end of the planting box 2 at the top of the support 11 through the infusion tube 33. The nutrient solution flows into the storage tank 21 of the planting box 2. As the nutrient solution accumulates in the storage tank 21, when the liquid level reaches the position of the filter screen 24, the excess nutrient solution is filtered through the filter screen 24, which intercepts impurities, plant roots, and other impurities. The filtered nutrient solution enters the liquid outlet tank 23. The nutrient solution entering the liquid outlet tank 23 passes through the liquid outlet 25 at the lower end, and is transported to the inlet end of the planting box 2 below through the spiral connection of the liquid outlet pipe 5. Repeat the above process, and the nutrient solution flows layer by layer downward, and finally the connection pipe 31 connected to the liquid outlet 25 of the planting box 2 at the bottom of the bottom support 11 re-transportes the excess nutrient solution in the last layer of planting box 2 back to the storage tank 3, forming a complete nutrient solution circulation supply;

[0043] When the planting box 2 needs to be thoroughly cleaned, first rotate the screw rod 122 to make the pressing plate 123 away from the planting box 2, and take the planting box 2 out of the placing rack 12. Lift the planting plate 4 upward to make the positioning rod 42 at the bottom of the planting plate 4 disengage from the mounting hole of the mounting frame 22, and disassemble the planting plate 4, to facilitate thorough cleaning and inspection of the planting plate 4 and the components inside the planting box 2, such as the storage tank 21, the liquid outlet tank 23, and the filter screen 24. After cleaning, reinstall the planting plate 4 and the planting box 2 according to the installation steps, and ensure that all components of the device are firmly installed. Start the pump 34 again to restore the nutrient solution circulation supply.
