Technical Field
[0001] This utility model is a farmland drainage filtration device, belonging to the field of farmland drainage technology. Background Technology
[0002] Farmland drainage refers to the artificial measures taken to remove excess surface water, soil water, and groundwater from farmland, improve the water, fertilizer, air, and heat relationship of the soil, and benefit crop growth. It involves removing excess surface water and groundwater from farmland, controlling surface runoff to eliminate waterlogging, and controlling groundwater levels to prevent waterlogging, soil marshland, and salinization. The fundamental task of farmland drainage is to create favorable conditions for improving agricultural production and ensuring high and stable yields.
[0003] Existing farmland drainage filtration equipment often suffers from clogged filters after prolonged use, requiring users to periodically remove and replace or clean them. This disassembly and reassembly process is time-consuming and labor-intensive, increasing the workload. There is an urgent need for a farmland drainage filtration device to solve these problems.

Detailed Implementation
[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figures 1-6 This utility model provides a technical solution: a farmland drainage filtration device, including a filter box 1, with water pipes 4 passing through and fixedly connected to both ends of the filter box 1, a filter collection box 7 slidably connected inside the filter box 1, two connecting plates 6 fixedly connected to the upper end of the filter collection box 7, and a sealing sliding cover 5 fixedly connected to the upper end of the two connecting plates 6, a fixed filter plate 8 fixedly connected inside the filter box 1, a cleaning push brush 10 slidably connected inside the filter box 1, a sliding plate 9 fixedly connected to the lower end of the cleaning push brush 10, and two push rods 17 fixedly connected to the right end of the cleaning push brush 10. The device has two fixed support seats 14, and a sliding tube 13 is fixedly connected to the left end of each of the two support seats 14. A spring 16 is fixedly connected between each of the two push rods 17 and the sliding tube 13. A rotating rod 11 is rotatably connected inside the filter box 1. A rotating disk 2 is fixedly connected to the upper end of the rotating rod 11, and a cam 12 is fixedly connected to the lower end of the rotating rod 11. This design solves the problem that in the original farmland drainage filtration equipment, the filter screen is easily clogged after long-term use, requiring users to regularly remove and replace or clean the internal filter screen, which is time-consuming and labor-intensive during disassembly and assembly, increasing labor intensity.
[0023] As the first embodiment of this utility model: A sealing block 3 is fixedly connected to the upper end of the filter box 1, and a sealing ring 20 is fixedly connected inside the sealing block 3. The sealing block 3 installed on the filter box 1 can be used to fix the sealing ring 20. When the filter box 1 and the water pipe 4 are draining, the sealing ring 20 can seal the gap between the filter box 1 and the sealing block 3 to prevent water from flowing out through the gap. Multiple support slide rods 15 are fixedly connected between the filter box 1 and the right end of the fixed filter plate 8. The sliding plate 9 is slidably connected to the multiple support slide rods 15. The support slide rods 15 installed between the filter box 1 and the fixed filter plate 8 can stably support the cleaning push brush 10 to slide inside the filter box 1, so that the brush of the cleaning push brush 10 pushes out the mud and blockages on the filter screen of the fixed filter plate 8. A support rotating seat 19 is fixedly connected to the lower end of the cam 12. The support rotating seat 19 is rotatably connected to the filter box 1. The sliding tube 13 installed at the bottom of the cam 12 can support the cam 12 to rotate stably inside the filter box 1, so that it pushes the sliding plate 9 to slide stably left and right. A sealing frame 18 is fixedly connected between the filter box 1 and the fixed filter plate 8, which increases the sealing between the sealing cover 5 and the filter box 1, preventing water from flowing out through the gap between the sealing cover 5 and the filter box 1. The cleaning push brush 10 cooperates with the fixed filter plate 8, and the cam 12 pushes the sliding plate 9 to the left, so that the brush on the surface of the cleaning push brush 10 pushes out the mud and blockages in the filter screen of the fixed filter plate 8.
[0024] As a second embodiment of this utility model: First, connect the two water pipes 4 to the farmland drainage pipe. When the farmland drainage pipe is filled with water, the water flows out through the fixed filter plate 8. The mud carried by the water flow will be blocked by the fixed filter plate 8 and fall into the filter collection box 7. When the mud and blockages clog the fixed filter plate 8, the user can hold the rotating disk 2 to drive the cam 12 to rotate, so that it pushes the sliding plate 9 to the left. The upper brush on the surface of the cleaning brush 10 pushes out the mud and blockages on the filter screen of the fixed filter plate 8. Then rotate the rotating disk 2 to drive the cam 12 to move the sliding plate 9 to the left. Release the sliding plate 9. The sliding plate 9 will pull the cleaning brush 10 to slide to the right under the elastic force of the spring 16. The cleaning purpose can be achieved without the user disassembling the equipment. Depending on the usage, the user can connect the external control motor to the rotating disk 2 and control the external motor to complete this operation through the control equipment. The cleaning can be completed automatically. If the water pipe 4 is still blocked after this operation, you can hold the handle on the surface of the sealing sliding cover 5 to remove the filter collection box 7 and drain the mud and blockage inside. Then slide the filter collection box 7 into the filter box 1.
