Openings are made in the inclined side walls, and cultivation troughs 8 are set in the openings. The LED lights 5 are set above the cultivation troughs 8, and both the LED lights 5 and the solar panels 1 are connected to the battery. The cultivation box 7 is equipped with a slide rail 12. The liquid supply system includes a water pipe 36, an atomizing nozzle 13, a nutrient solution tank 21, a water and fertilizer pipe 29, a valve 19, a flow detector 20, a fertilizer tank 17, a phosphate tank 18, a weight detector 31, and a flow meter 12. A metering pump 28, a stirrer 25, and a controller 10 are included. A water pipe 36 is slidably mounted on a slide rail 12. An atomizing nozzle 13 is installed on the water pipe 36 and faces the cultivation trough 8.

The flow detector 20, the weight detector 31, and the valve 19 are respectively connected to the controller 10.

[0043] In this embodiment of the sweet potato aeroponic cultivation device, the bottom area of ​​the cultivation box 7 is larger than the top area, such as... Figure 1 As shown, the left and right side walls of the cultivation box 7 are rectangular surfaces that slope inward, while the front and rear side walls are vertical isosceles trapezoidal surfaces. That is, the left and right side walls of the cultivation box 7 are sloped side walls.

[0065] Sweet potatoes are planted on cultivation board 801, and the roots and sweet potatoes can grow and develop in cultivation trough 802.

[0066] The cultivation trough 802 can be a rectangular trough, and the cultivation board 801 can be a rectangular board. The cultivation board 801 can have small holes in which sweet potato seedlings are placed, and their roots grow within the cultivation trough 802. The cultivation board 801 can be a floating board used for hydroponics of leafy vegetables, as per existing technology.

[0067] like Figure 1 and Figure 3 As shown, specifically, the other two opposite side walls of the cultivation box 7 are set as vertical side walls, one of which is equipped with an exhaust fan 9 and the other with an opening and closing door 11; the controller 10 is installed on one of the vertical side walls and is equipped with a control panel 16; the cultivation box 7 is equipped with a pipe rack 35, and the liquid inlet pipe 15 is connected to the pipe rack 35.

[0068] If the humidity inside the cultivation box 7 is too high, the exhaust fan 9 can be turned on to reduce the humidity.

[0069] The exhaust fan 9, the opening and closing door 11, the controller 10, and the control panel 16 can all be installed on one side wall of the cultivation box 7, for example, on the front or rear side wall. The liquid inlet pipe 15 and the pipe rack 35 are both installed inside the cultivation box 7.

[0070] like Figure 1 and Figure 12 As shown, specifically, the nutrient solution tank 21 is connected to the distilled water generator 14 through the water and fertilizer pipe 29. The top surface of the nutrient solution tank 21 is provided with a filter tank 22, which is located below the cultivation trough 8 and has a filter plate 34 inside. The stirrer 25 is connected to the motor 23 through a gear set and a transmission rod 24.

[0071] Tap water enters the distilled water generator 14, and the distilled water produced by the generator 14 is then fed into the nutrient solution tank 21 through the water-fertilizer pipe 29. The nutrient solution falling into the nutrient solution tank 21 is filtered by the filter plate 34.

[0072] The distilled water generator 14 can be installed inside the cultivation box 7. The filter tank 22 can be configured as a through-hole structure, that is, a through-hole filter tank 22 is opened on the top surface of the nutrient solution tank 21, and a filter plate 34 is installed inside the filter tank 22. The outer side wall of the filter plate 34 can be connected to the inner side wall of the filter tank 22.

[0073] like Figure 1As shown, the motor 23 can be located at the bottom of the cultivation box 7, that is, the motor 23 can be located on the outside of the cultivation box 7, below it, to separate it from the cultivation system. The motor 23 and the transmission rod 24 can be installed in the nutrient solution tank 21. The output shaft of the motor 23 is provided with a first gear, one end of the transmission rod 24 is provided with a second gear that meshes with the first gear, and the other end of the transmission rod 24 is provided with a first bevel gear. The bottom end of the stirrer 25 is provided with a second bevel gear that meshes with the first bevel gear.

[0074] like Figure 1 and Figure 11 As shown, specifically, the nutrient solution tank 21 is equipped with an EC detector 26, a pH detector 27, and a water level detector 32, which are connected to the controller 10.

[0075] The EC and pH values ​​of the nutrient solution in the nutrient solution tank 21 can be monitored by the EC detector 26 and pH detector 27, respectively, and the values ​​are transmitted to the controller 10. The EC value is an indicator of the salt content of irrigation water or soil solution, used to determine the amount of fertilizer added. When the EC and pH values ​​of the nutrient solution in the nutrient solution tank 21 reach the preset values, the controller 10 controls the valve 19 to close, stopping the fertilizer supply.

[0076] The valves 19 of each fertilizer tank 17, phosphoric acid tank 18, and nutrient solution tank 21 are only opened during nutrient solution preparation. The delivery of water, fertilizer, and phosphoric acid can be stopped at preset intervals, and the stirrer 25 can be started to mix the liquid evenly. The stirrer 25 is then turned off. EC and pH values ​​are monitored continuously, and this process is repeated until the nutrient solution in nutrient solution tank 21 reaches the preset volume, preset EC value, and preset pH value. When stirring is required, the motor 23 starts, causing the stirrer 25 to rotate via the transmission rod 24. The nutrient solution in nutrient solution tank 21 is delivered to the inlet pipe 15 via the flow pump 28 and atomized by the atomizing nozzle 13, spraying the roots of the sweet potatoes in the cultivation trough 8. The water level detector 32 can detect the volume of the nutrient solution in nutrient solution tank 21. When the water level is lower than the preset height, the water level detector 32 transmits a signal to the controller 10 to initiate the solution preparation process. The controller 10 can set the irrigation time and frequency, and the LED lights can be controlled by the controller 10 to adjust the light quality, light intensity and illumination time.

[0077] The EC detector 26 and pH detector 27 can be installed at the bottom of the nutrient solution tank 21.

[0079] The inclined block 30 facilitates the complete outflow of liquid from fertilizer tank 17 and phosphate tank 18.

[0080] like Figure 1 and Figure 8 As shown, specifically, the slide rail 12 is U-shaped, and the two sides of the slide rail 12 are respectively set on one side of the two inclined side walls of the cultivation box 7; the U-shaped slide rail 12 facilitates the water pipe 36 to drive the atomizing nozzle 13 to the cultivation trough 8 on the inclined side walls on both sides.

[0081] like Figure 1 and Figure 2 As shown, at least two cultivation troughs 8 are respectively provided on the two inclined side walls, and multiple cultivation troughs 8 are evenly arranged from top to bottom.

[0082] The cultivation box 7 has at least two openings on its two inclined side walls, and multiple openings can be evenly arranged in rows and columns, with the openings in adjacent rows and columns being staggered; thus, multiple cultivation troughs 8 can be set on each inclined side wall, and the multiple cultivation troughs 8 can be evenly arranged in rows and columns, with the cultivation troughs 8 in adjacent rows and columns being staggered.

[0083] like Figure 1 and Figure 8 As shown, specifically, the slide rail 12 is set on the top surface of the cultivation box 7 and is set as a T-shaped groove; the top of the water pipe 36 is set with a T-shaped slider, which is movably set in the T-shaped groove.

[0084] The T-shaped slider is movable in the T-slot, which can prevent the water pipe 36 from falling and allow the water pipe 36 to move along the slide rail 12.

[0085] The inner diameter of the upper horizontal portion of the T-slot can be greater than the outer diameter of the upper horizontal portion of the T-slide block, so that the T-slide block can slide and turn in the U-shaped slide rail 12. At the same time, the outer diameter of the upper horizontal portion of the T-slide block should be greater than the inner diameter of the lower vertical portion of the T-slot, to prevent the T-slide block from falling out of the T-slot.

[0086] The inner diameter height of the upper horizontal portion of the T-slot can be greater than the outer diameter height of the upper horizontal portion of the T-slide block, and the inner diameter width of the lower vertical portion of the T-slot can be greater than the outer diameter width of the lower vertical portion of the T-slide block, to facilitate smooth sliding of the T-slide block in the slide rail 12. Figure 1 and Figure 2 , Figure 11 As shown, specifically, the top surface of the nutrient solution tank 21 is set as the bottom surface of the cultivation box 7, that is, the cultivation box 7 and the nutrient solution tank 21 can be separated by a floor or partition.

[0087] The nutrient solution tank 21 can be configured as a rectangular box, with its top surface coinciding with the bottom surface of the cultivation box 7.
