[0020] Please refer to Figures 1-3 , the embodiments of the present invention provide a technical solution: a rice hydroponic device, including a hydroponic box 1. Inside the hydroponic box 1, there is a fixing frame 4. A number of fixing rings 7 are evenly arranged on the fixing frame 4. A hydroponic cylinder 6 is inlaid and connected in the fixing ring 7. In the middle of the fixing frame 4, there is a fixing pipe 5. In the middle of the surface of the fixing pipe 5, there is a threaded hole 11. Four annularly distributed limiting holes 12 are arranged on the surface of the fixing plate with the threaded hole 11 as the center. Vertically arranged on the inner bottom of the hydroponic box 1 are a screw rod 14 and a limiting column 10. The limiting column 10 is fixedly connected to the hydroponic box 1, and the screw rod 14 is rotatably connected to the hydroponic box 1. In the middle of the bottom surface of the hydroponic box 1, there is a motor 15, and the power output end of the motor 15 is connected to the lower end of the screw rod 14. The upper end of the screw rod 14 extends into the threaded hole 11 and is threadedly connected to the threaded hole 11. The upper end of the limiting column 10 extends into the limiting hole 12 and is movably connected to the limiting hole 12. After the motor 15 is started, it can drive the fixing pipe 5 to perform vertical displacement, thereby adjusting the height of the fixing frame 4. After the height of the fixing frame 4 is adjusted, the contact height between the rice and the culture solution can be adjusted. After the fixing frame 4 continues to move upward, it is also convenient to observe the growth of the rice roots.

[0021] Furthermore, at the upper end of the outer wall of the hydroponic box 1, there is a liquid return pipe 2. A liquid return hole 3 communicating with the liquid return pipe 2 is opened on the inner wall of the hydroponic box 1. At the bottom of the hydroponic box 1, there is a liquid guide ring 13, and the upper end of the liquid guide ring 13 is communicated with the inside of the hydroponic box 1.

[0022] Furthermore, a filter box 8 is installed on the outer wall of the hydroponic box 1. At the top and bottom of the filter box 8, there are pipes 9. The pipe 9 located at the top of the filter box 8 is connected to the liquid return pipe 2, and the liquid return pipe 2 located at the bottom of the filter box 8 is connected to the liquid guide ring 13. In the middle of the filter box 8, there is a partition 20. Inside the filter box 8, there is a filter plate 16 vertically connected. On one side of the inner bottom of the filter box 8, there is a pump 19. The upper end of the filter plate 16 extends above the filter box 8 and is fixedly connected to the filter box 8 with bolts. The filter plate 16 penetrates through the partition 20 and has liquid guide holes 17 on its surface. On the surface of the filter plate 16 and opposite to the liquid guide holes 17, there is a filter net 18. After the pump 19 pumps out the culture solution, it is filtered through the filter net 18 at the lower end of the filter plate 16, and then filtered multiple times through the filter net 18 at the upper end of the filter plate 16, and then discharged, reducing the particulate matter in the culture solution.

[0023] Working principle: Pour the nutrient solution into the hydroponic box 1, plant the rice in the hydroponic cylinder 6, then insert the hydroponic cylinder 6 into the fixing ring 7, and adjust the height of the fixing frame 4 by starting the motor 15, thereby adjusting the contact height between the rice and the nutrient solution. Start the pump 19 to pump out the nutrient solution at the bottom, and after filtering, it returns to the hydroponic box 1 through the liquid return hole 3. When it is necessary to observe the growth of the rice, start the motor 15, continuously move the fixing tube 5 upward and drive the fixing frame 4, and the root system of the rice can be viewed by observing the lower end of the hydroponic cylinder 6.
