Description

Technical Field

[0001] The invention relates to the technical field of agricultural farmland management equipment, and in particular to an agricultural drainage device capable of filtering soil. Background Art

[0002] Floods and waterlogging disasters can cause serious damage to farmland and affect the growth of crops. Farmers often use artificial drainage to control flood disasters. The commonly used artificial drainage method is to use a drainage pump to drain excess water from the farmland to control surface runoff and eliminate waterlogging. At the same time, it controls the groundwater level and prevents waterlogging and soil swamping and salinization. Its fundamental task is to improve agricultural production conditions and ensure high and stable yields of crops.

[0003] For traditional artificial drainage of farmland, when the drainage pump is started and running at full capacity, its strong suction not only acts on the water, but also inevitably pulls the surrounding soil particles, especially in areas where the soil is loose or has a high water content. The mixture of soil and water is sucked away from the surface of the farmland under the strong suction of the drainage pump. The flow of this mixture not only takes away precious soil resources, but may also lead to a decrease in soil fertility; at the same time, the soil in the mixture is transferred to the water storage area, which will also lead to an increase in the amount of soil in the water storage area and damage the original water environment. Summary of the invention

The mixture of soil and water is sucked away from the surface of the farmland together under the strong suction force of the drainage pump. The flow of this mixture not only takes away precious soil resources, but may also cause a decrease in soil fertility; at the same time, the soil in the mixture is transferred to the water storage area, which will also lead to an increase in the amount of soil in the water storage area and damage the original water environment.

The driven sprocket 502 is connected to the linkage driving sprocket 201 through a chain to form a chain transmission; the dual-axis driving motor 2 drives the driving roller 501 to rotate through the chain transmission of the driven sprocket 502 and the linkage driving sprocket 201, and the rear end of the conveyor belt side bracket 5 is rotatably connected to the driven roller 503 through a bearing, and the driving roller 501 is connected to the driven roller 503 through a bearing. Two side traction belts 504 are installed on the roller 501 and the driven roller 503.

The cooperation of the active roller 501, the driven roller 503, the side traction belt 504 and the soil separation filter 505 and the transmission mechanism of the linkage active sprocket 201 and the driven sprocket 502 form a circulating filter. The active roller 501 drives the side traction belt 504 to move on the active roller 501 and the driven roller 503. The soil separation filter 505 rotates and drives the soil separation filter 505 to rotate, transferring the soil separation filter 505 with soil accumulated inside the soil separation box 6 backward, and detaching from the outer surface of the soil separation filter 505 under the action of gravity and inertia and then falling into the farmland, thereby realizing the soil recovery function and avoiding soil loss and damage to the farmland.

[0025] In the disclosed embodiment, a separation drainage pipe 603 is connected through the right wall of the first box body 601, and the part of the separation drainage pipe 603 located inside the first box body 601 extends forward in an "L"-shaped bending structure, so that the second centrifugal pump body 4 is connected to the inside of the soil separation box 6 through the separation drainage pipe 603, and the filtered water inside the soil separation box 6 is connected to the second centrifugal pump body 4 through the separation drainage pipe 603. The soil separation box 6 is separated in the middle by a soil separation filter 505. When water mixed with soil enters the soil separation box 6 through the separation water inlet pipe 605, the mixture of soil and water flows downward under the action of gravity, and the water in the mixture passes through the soil separation filter 505 and enters the first box body 601 for temporary storage, while the soil is intercepted by the soil separation filter 505 and cannot enter the first box body 601, effectively avoiding the loss of soil as the mixture formed by soil and water under the strong suction of the water pump is sucked away from the surface of the farmland.

[0026] Embodiment 2, on the basis of embodiment 1, a conveyor belt inlet 604 is provided at the front edge of the second box body 602, and a separation water inlet connecting pipe 605 is fixedly connected to the left side of the second box body 602, and the separation water inlet connecting pipe 605 is connected to the second box body 602; a soil discharge outlet 606 is provided at the rear edge of the second box body 602, and the side traction belt 504 is movably connected with the soil separation filter 505 and passes through the conveyor belt inlet 604 and the soil discharge outlet 606. The side traction belt 504 and the soil separation filter 505 are driven by the active roller 501 to pass through the conveyor belt inlet 604 and the soil discharge outlet 606 to circulate through the inside of the soil separation box 6 and participate in filtration, so that the soil screened above the soil separation filter 505 can be transported backwards and fall as the soil separation filter 505 turns over, thereby effectively reducing the loss of soil in the farmland.

[0027] The working principle of this embodiment is as follows: first, the drainage device is placed in the farmland that requires artificial drainage, the water inlet pipe 7 is connected to the excess water in the farmland through a water pipe, the dual-axis drive motor 2 is powered on, and the impellers inside the first centrifugal pump body 3 and the second centrifugal pump body 4 are driven to operate through the rotating shafts at both ends of the dual-axis drive motor 2. The water mixed with soil is transported into the second box body 602 through the separation water inlet pipe 605 through the first centrifugal pump body 3. The mixture of soil and water flows downward under the action of gravity, and the water in the mixture passes through the soil separation filter 505 and enters the first box body 601 for temporary storage. The soil is intercepted by the soil separation filter 505 and cannot enter the first box body 601. At the same time, the filtered water entering the first box body 601 is discharged outward through the separation drainage pipe 603 and the second centrifugal pump body 4. The drainage pipe 8 is connected to a water pipe to allow the filtered water to flow outward. The water is discharged to the designated area. At the same time, the dual-axis drive motor 2 drives the active roller 501 to rotate through the chain transmission of the linkage active sprocket 201 and the driven sprocket 502. After the soil and water mixture inside the soil separation box 6 passes through the soil separation filter 505 to intercept most of the soil, as the active roller 501 and the driven roller 503 drive the side traction belt 504 to operate, the soil separation filter 505 covered with soil sediment inside the soil separation box 6 is transferred backward, and under the action of gravity and inertia, it detaches from the outer surface of the soil separation filter 505 and falls into the farmland, and the clean soil separation filter 505 is conveyed from front to back through the conveyor belt inlet 604 into the soil separation box 6 for filtration, thereby avoiding soil precipitation and clogging the filter, resulting in reduced filtration effect and increased water flow resistance, so that the equipment always maintains efficient soil separation and soil recovery, and reduces soil loss in farmland.
