Specific embodiments

[0027] The present utility model will be described in detail below with reference to the accompanying drawings.

[0028] As Figures 1 to 5 shown, an automatic circulating liquid supply aeroponic cultivation device includes a cultivation box 1, a planting plate 2, a support plate 3, a support frame 4, an isolation net 5, a liquid collection plate 6, a filter 7, a return pipe 8, an ultraviolet sterilizer 9, a circulation tank 10, a drain pipe 11, a liquid level sensor 12, a liquid supply pipe 13, a water pump 14, a distribution pipe 15, an atomizing nozzle 16, a connecting pipe 17, an electromagnetic valve 18, a liquid storage tank 19, a feed pipe 20, a stirring device 21, a control box 22, and a support base 23.

[0029] As Figures 1 to 3 shown, the cultivation box 1 is divided into upper and lower chambers by the liquid collection plate 6. The upper chamber is mainly used as the growth area for the roots of cultivated plants, and the lower chamber is mainly used as the working area for the circulation and return of nutrient solution. The side wall of the lower chamber of the cultivation box 1 is made into a flat door, which is convenient for the maintenance and replacement of the equipment in the chamber.

[0030] The planting plate 2 is provided with evenly spaced planting holes and is placed on the support plate 3 inside the cultivation box 1, and the top surface of the planting plate 2 is at the same horizontal plane as the top surface of the cultivation box 1. The planting plate 2 can be installed and disassembled, and the planting plate 2 can be taken down from the upper port of the cultivation box 1 at any time. On the one hand, it is convenient to observe the growth of the roots of cultivated plants, and on the other hand, it is convenient for the maintenance, replacement and cleaning of equipment such as the isolation net 5 and the atomizing nozzle 16 inside the cultivation box 1.

[0031] As Figure 2 and Figure 3As shown, the support plate 3 is fixed at an appropriate position on the inner wall of the cultivation box 1 for placing the planting plate 2. The support frame 4 is fixed at an appropriate position on the inner wall of the cultivation box 1, below the support plate 3, for placing the distribution pipe 15.

[0032] The isolation net 5 is located inside the cultivation box 1, below the support frame 4, and is fixed on the liquid collection plate 6 to prevent broken roots, debris, etc. from falling on the liquid collection plate 6 during the growth of cultivated plants and blocking the filter 7.

[0033] As Figure 2 , Figure 3 and Figure 5 shown, the liquid collection plate 6 is in an irregular V-shaped groove plate structure, fixed on the inner wall of the cultivation box 1, below the isolation net 5, to facilitate the collection of excess nutrient solution not absorbed by the roots of cultivated plants.

[0034] The filter 7 is located in the lower cavity of the cultivation box 1, below the liquid collection plate 6. One end is installed at the bottom of the liquid collection plate 6, and the other end is connected to the return pipe 8, for filtering impurities in the returned nutrient solution.

[0035] The return pipe 8 is located in the lower cavity of the cultivation box 1, and both ends are respectively connected to the filter 7 and the circulation box 10, which is the channel for the nutrient solution to flow back to the circulation box 10. The ultraviolet sterilizer 9 is installed on the return pipe 8 to kill bacteria in the returned nutrient solution.

[0036] A partition is installed at the lower end of the circulation box 10, placed at the bottom of the cultivation box 1, for storing the nutrient solution, which is the source for the water pump 14 to directly extract the nutrient solution and the nutrient solution return storage area. The drain pipe 11 is installed at the bottom of the circulation box 10, with a valve installed on it, for discharging the remaining nutrient solution in the circulation box 10.

[0037] The liquid level sensor 12 is installed on the inner side wall of the circulation box 10 to detect the liquid level height of the nutrient solution in the circulation box 10. The liquid level sensor 12 sets a threshold range, which is regulated by the control box 22. When the water level height is lower than the set minimum value, the control box 22 receives the signal sent by the liquid level sensor 12 and will automatically open the solenoid valve 18, and the nutrient solution in the storage tank 19 will flow into the circulation box 10 through the connecting pipe 17; when the water level height is higher than the set maximum value, the liquid level sensor 12 will send a signal, and the control box 22 will control the solenoid valve 18 to close, and the storage tank 19 will no longer supply the nutrient solution to the circulation box 10.

[0038] The supply pipe 13 is located at the bottom and on the right side inside the cultivation box 1, and is divided into two sections of pipes by the water pump 14. Both ends are respectively connected to the circulation box 10 and the distribution pipe 15. The water pump 14 is installed between the supply pipes 13, for pumping the nutrient solution in the circulation box 10. The water pump 14 is regulated by the circulation controller in the control box 22, and the running time and intermittent time can be set.

[0039] The distribution pipe 15 is placed on the support frame 4 and arranged horizontally. The inlet port is connected to the liquid supply pipe 13 and is used for the uniform diversion of the nutrient solution. On the outer wall directly above the distribution pipe 15, several atomizing nozzles 16 are evenly installed at intervals. The atomizing nozzles 16 can atomize the nutrient solution and spray it onto the roots of the cultivated plants.

[0040] As Figures 2 to 4 shown, one end of the connecting pipe 17 is located inside the cultivation box 1 and is connected to the circulation box 10, and one end passes through the side wall of the cultivation box 1 and is connected to the liquid storage box 19. The electromagnetic valve 18 is installed on the connecting pipe 17 outside the cultivation box 1, below the liquid storage box 19, and is used to control the connection and cut-off of the nutrient solution in the connecting pipe 17. The electromagnetic valve 18 is regulated by the control box 22 and can be automatically opened and closed.

[0041] The liquid storage box 19 is placed on the support base 23 and is a container for configuring and storing the nutrient solution. The support base 23 supports the liquid storage box 19 and ensures that the liquid storage box 19 is higher than the circulation box 10, which is convenient for realizing automatic liquid supply when the electromagnetic valve 18 is opened.

[0042] The feed pipe 20 is installed on the outer wall of the upper side of the liquid storage box 19 and has two pipe orifices, which are the inlet ports for water and concentrated nutrient solution respectively. The stirring device 21 is composed of a motor 2101 and a stirring paddle 2102. The output end of the motor 2101 is connected to the stirring paddle 2102. The motor 2101 is installed on the outer wall of the upper side of the liquid storage box 19, and the stirring paddle 2102 is located inside the liquid storage box 19. The stirring device 21 is used to stir the mixture of water and concentrated nutrient solution raw materials to dilute it to the nutrient solution concentration required by the plants.

[0043] The control box 22 is located on the outer wall of the liquid storage box 19 and is composed of a signal controller, a circulation controller, a signal processor, a start switch, etc. It is connected to the ultraviolet sterilizer 9, the liquid level sensor 12, the water pump 14, the electromagnetic valve 18, the motor 2101 of the stirring device 21, etc. through wires respectively. The device is controlled through the electric control box 22 to realize the effective operation of each device of the device.

[0044] The working principle of the present utility model is as follows: Plants are cultivated on the planting board. The water pump extracts nutrient solution from the circulation tank, flows through the liquid supply pipe and the distribution pipe, and enters the atomizing nozzle. The atomized nutrient solution is sprayed onto the roots of the plants to provide the nutrients required for plant growth. The unabsorbed nutrient solution removes sundries such as broken roots and leaves through the isolation net, converges on the liquid collection board, flows through the filter to remove impurities, flows through the ultraviolet sterilizer for disinfection and sterilization, and enters the circulation tank through the return pipe. The above process forms a circulating liquid supply system, effectively improving the utilization efficiency of the nutrient solution. The liquid level sensor in the circulation tank can detect the liquid level height of the nutrient solution, and a threshold range is set. The liquid level sensor is regulated by the control box. When the water level height is lower than the set minimum value, the control box receives the signal transmitted by the liquid level sensor and will automatically open the solenoid valve. The nutrient solution in the storage tank flows into the circulation tank through the connecting pipe; when the water level height is higher than the set maximum value, the control box receives the signal transmitted by the liquid level sensor and will control the solenoid valve to close, and the storage tank will no longer supply liquid to the circulation tank. The above process forms an automatic liquid supply system, improving the working efficiency. At the same time, the present utility model also has the function of diluting and configuring the nutrient solution. Water and concentrated nutrient solution are added from the feed pipe according to certain proportion requirements, and the stirring device is used to evenly mix the water and the concentrated nutrient solution into the required nutrient solution, which is stored in the storage tank. When the solenoid valve automatically opens, it can supply liquid to the circulation tank to ensure the continuous operation of the circulating liquid supply system.

[0045] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the embodiments are limited only to these descriptions. Without departing from the concept of the present utility model, it should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
