Description

Technical Field

[0001] This utility model relates to the field of hydroponic boxes for agricultural planting, and in particular to an automatic water replenishment hydroponic box for agricultural planting. Background Technology

[0002] A hydroponic box is a device used for soilless cultivation, which replaces traditional soil cultivation by immersing plant roots in a nutrient solution.

[0003] A search revealed a utility model patent with application number 202322083499.4, entitled "An Agricultural Hydroponic Box." This patented device uses a liquid level sensor to detect whether the water level in the hydroponic box is below a threshold. If it is below the threshold, a water pump provides power to extract water from the tank and deliver it through a water supply pipe to an outlet pipe, supplying water to the vegetables on the cultivation board. This also increases the water volume inside the hydroponic box, creating a better growing environment for the hydroponic plants.

[0004] However, this patented device may fail to adjust the liquid level according to the plant's needs, resulting in substandard liquid levels that restrict plant growth and affect the device's nutrient supply to the plant. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic water replenishment hydroponic box for agricultural planting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic watering hydroponic box for agricultural planting includes a top box, an adjustment mechanism inside the top box, and a bottom cylinder fixedly connected between the inner and outer walls of the bottom of the top box. The top of the top box is detachably connected to an opening and closing plate. A rotating cylinder is rotatably connected to the inner wall of the circumferential side of the bottom cylinder. The top of the rotating cylinder extends to the top outer wall of the opening and closing plate. A lifting ring plate is threadedly connected to the inner wall of the bottom of the circumferential side of the rotating cylinder. An opening aligned with the lifting ring plate is provided between the inner and outer walls of the bottom of the bottom cylinder. Fixed cylinders are detachably connected evenly between the top and bottom of the opening and closing plate.

[0008] Preferably, the inner and outer walls of the circumferential side of the rotating cylinder are evenly provided with slots located above the lifting ring plate, and the bottom of the lifting ring plate is provided with at least two square slots. The inner walls of the sides of the square slots are slidably connected to limit plates, and the bottom of the limit plates are fixedly connected to the bottom inner wall of the bottom cylinder.

[0009] Preferably, the bottom outer wall of the top box is detachably connected to the bottom box, the top of the bottom box is detachably connected to the second opening and closing plate, the circumferential side of the bottom cylinder is detachably connected to the inside of the second opening and closing plate, and a through hole is provided between the top end and the bottom end of the second opening and closing plate.

[0010] Preferably, a connecting pipe aligned with the through hole is fixedly connected to the bottom outer wall of the top box, and the other end of the connecting pipe extends to the bottom of the first opening and closing plate. A pump aligned with the connecting pipe is fixedly connected to the bottom of the second opening and closing plate.

[0011] Preferably, one end of the pump is fixedly connected to a fixed pipe 1 located inside the bottom box, and the other end of the pump is fixedly connected to a fixed pipe 2 located inside the connecting pipe. A discharge chute is provided between the inner wall of the circumferential side of the fixed pipe 2 and the outer wall of the circumferential side of the connecting pipe.

[0012] Preferably, a circular plate located above the second fixed pipe is slidably connected to the inner wall of the circumferential side of the connecting pipe. The bottom of the circular plate abuts against the top of the second fixed pipe. A spring is fixedly connected between the top of the circular plate and the inner wall of the top of the connecting pipe. Limiting grooves are evenly provided on the inner wall of the circumferential side of the connecting pipe. Limiting blocks aligned with the limiting grooves are evenly fixedly connected to the circumferential side of the circular plate. One side of the limiting block is slidably connected to one inner wall of the limiting groove.

[0013] Preferably, the rotating cylinder has a detachable opening and closing block located outside the top box. The bottom of the opening and closing block is fixedly connected to a connecting column, and the other end of the connecting column has a fixedly connected connecting ring on its circumferential side. The connecting ring abuts against the top of the lifting ring plate, and a filter screen is evenly fixedly connected between the top and bottom of the connecting ring.

[0014] Compared with the prior art, this utility model provides an automatic watering hydroponic box for agricultural planting, which has the following beneficial effects:

[0015] Multiple fixed cylinders are placed into the top box via a rotating drum, and plants are inserted into these cylinders. Nutrient solution is added to both the top and bottom boxes. The bottom cylinder and connecting pipe at the bottom of the top box are aligned with the second opening plate, so that the bottom cylinder is inserted into the second opening plate, and the second fixed pipe is inserted into the inside of the connecting pipe. Simultaneously, the second fixed pipe lifts the circular plate, aligning the discharge chute on the second fixed pipe and the connecting pipe. During disassembly and assembly, the top box can be lifted to separate the top and bottom boxes, improving the convenience of disassembly, assembly, and maintenance. Rotating the rotating drum causes the lifting ring plate to rise. As the lifting ring plate rises, it blocks the slots, allowing the device to adjust the nutrient solution level according to the plant's planting requirements, preventing the plant from failing due to insufficient nutrient solution level. Limited plant growth affects the device's nutrient supply to the plants. Starting the pump allows the nutrient solution in the bottom tank to gradually and slowly flow along fixed pipe one, fixed pipe two, and the discharge chute into the top tank. This ensures the relatively abundant nutrient solution in the bottom tank is gradually delivered to the top tank, supplementing the plants with various nutrients. This helps the device maintain sufficient nutrients for the plants during long-term growth, preventing them from consuming excessive nutrients and failing to grow normally. As the nutrient solution in the top tank gradually rises, it passes over the lifting ring plate and is filtered through the filter screen before entering the bottom tank. This facilitates the filter screen's removal of impurities and debris from the top tank, preventing pump blockage, improving the stability of the device's operation, and reducing the workload of subsequent cleaning.

A fixed cylinder 2 is detachably connected evenly between the top and bottom of the opening and closing plate 3.

[0022] In this utility model, a slot 13 is evenly provided between the inner and outer walls of the circumferential side of the rotating cylinder 7, located above the lifting ring plate 14. At least two square slots are provided at the bottom of the lifting ring plate 14. A limiting plate 16 is slidably connected to the inner wall of the side of the square slot. The bottom of the limiting plate 16 is fixedly connected to the bottom inner wall of the bottom cylinder 17.

[0023] The bottom outer wall of the top box 1 is detachably connected to the bottom box 5, the top of the bottom box is detachably connected to the second opening plate 4, the circumferential side of the bottom cylinder 17 is detachably connected to the inside of the second opening plate 4, and a through hole 22 is provided between the top end and the bottom end of the second opening plate 4.

[0024] A connecting pipe 10 aligned with the through hole 22 is fixedly connected to the bottom outer wall of the top box 1. The other end of the connecting pipe 10 extends to the bottom of the opening and closing plate 3. A pump 9 aligned with the connecting pipe 10 is fixedly connected to the bottom of the opening and closing plate 4.

[0025] One end of the pump 9 is fixedly connected to a fixed pipe 8 located inside the bottom box 5, and the other end of the pump 9 is fixedly connected to a fixed pipe 21 located inside the connecting pipe 10. A discharge chute 20 is provided between the inner wall of the circumferential side of the fixed pipe 21 and the outer wall of the circumferential side of the connecting pipe 10.

[0026] A circular plate 25 located above the fixed pipe 21 is slidably connected to the inner wall of the circumferential side of the connecting pipe 10. The bottom of the circular plate 25 abuts against the top of the fixed pipe 21. A spring 11 is fixedly connected between the top of the circular plate 25 and the top inner wall of the connecting pipe 10. Limiting grooves 23 are evenly opened on the inner wall of the circumferential side of the connecting pipe 10. Limiting blocks 24 aligned with the limiting grooves 23 are evenly fixedly connected to the circumferential side of the circular plate 25. One side of the limiting block 24 is slidably connected to one inner wall of the limiting groove 23.

[0027] The rotating cylinder 7 is detachably connected to an opening and closing block 6 located outside the top box 1. A connecting column 12 is fixedly connected to the bottom of the opening and closing block 6. A connecting ring 19 is fixedly connected to the other end of the connecting column 12.

[0028] Working principle: Multiple fixed cylinders 2 are placed in the top box 1, and the plants are inserted into the fixed cylinders 2. Nutrient solution is added to both the top box 1 and the bottom box 5. The bottom cylinder 17 and the connecting pipe 10 at the bottom of the top box 1 are aligned with the second opening plate 4, so that the bottom cylinder 17 is inserted into the second opening plate 4, and the second fixed pipe 21 is inserted into the inside of the connecting pipe 10. At the same time, the second fixed pipe 21 lifts the circular plate 25, so that the discharge chute 20 on the second fixed pipe 21 and the connecting pipe 10 are aligned. When disassembling the device, lifting the top box 1 can separate the top box 1 and the bottom box 5, which improves the convenience of disassembly, assembly and maintenance. Rotating the rotating cylinder 7 drives the lifting ring plate 14 to rise. When the lifting ring plate 14 rises, it blocks the slot 13, which helps the device to adjust the water level of the nutrient solution in the device according to the planting requirements of the plants and prevents the solution from being damaged due to uneven liquid level. If the nutrient solution in the bottom tank 5 is not met, the plant growth will be restricted, affecting the nutrient supply effect of the device. Pump 9 is started. Pump 9 drives the nutrient solution in the bottom tank 5 to slowly flow into the top tank 1 along the fixed pipe 1 8, fixed pipe 21 and discharge chute 20. This allows the relatively abundant nutrient solution in the bottom tank 5 to be gradually sent into the top tank 1, supplementing the plants in the top tank 1 with various nutrients. This helps the device maintain sufficient nutrients for the plants during long-term growth and prevents the plants from consuming too much nutrients and failing to grow normally. As the nutrient solution in the top tank 1 gradually rises, it passes over the lifting ring plate 14 and is filtered by the filter screen 14 before entering the bottom tank 5. This helps the filter screen 15 to filter impurities and debris in the top tank 1, preventing the pump 9 from becoming clogged, improving the stability of the device's operation, and reducing the workload of subsequent cleaning of the device.
