Description

Technical Field

[0001] This application relates to the field of farmland drainage purification technology, specifically a farmland drainage river water purification device. Background Technology

[0002] The excessive use of fertilizers and pesticides in crop cultivation and the indiscriminate discharge of livestock and poultry manure in animal husbandry have exceeded the nutrient load of farmland, resulting in an excess of nutrients such as nitrogen, phosphorus, and potassium. These excess nutrients left in the soil enter water bodies under the action of rainwater, thus causing surface water pollution. This pollution not only damages the soil structure of arable land and accelerates its nutrient loss, but also promotes severe soil compaction.

[0003] Currently, commonly used methods for purifying farmland drainage are described in the instruction manual. Figure 5 As shown, water in farmland flows into drainage canals through drainage ditches, and then the drainage canals transport the water to wetlands. The artificial wetlands purify the water quality of farmland drainage, reducing the concentration of nutrients in the drainage. This can alleviate nitrate pollution in groundwater and surface water in the planting area, and the wetland water can also be used as an irrigation source, achieving the supply of irrigation water resources for farmland as needed. At the same time, it does not damage the natural ecology and can also achieve the effect of landscaping. Chinese patent (publication number: CN207451740U) discloses a farmland drainage system for purifying water quality. By setting up a filtration zone, the filtration effect can be improved and the removal rate of nitrogen organic matter can be increased.

[0004] When farmland is drained, stones and debris are carried into the drainage ditch by the water flow. When the water flow carries the stones and debris through the filtration area, they will accumulate there, causing blockage of the filtration area. This makes the water flow into the wetland slower and reduces the wetland's water purification efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a farmland drainage river water purification device that has advantages such as being less prone to clogging, thus solving the problem of easy clogging.

[0006] To achieve the above objectives, this application provides the following technical solution: a farmland drainage river water purification device, including a filter plate, a connecting plate fixed to the front wall of the filter plate, a moving plate provided at the front end of the connecting plate, and a processing component provided at the front end of the filter plate;

[0007] The processing assembly includes a lifting plate, two lead screws, a worm gear, two threaded cylinders, a worm gear sleeve fixedly installed on the outer surface of the threaded cylinders, a first motor fixedly installed on the left end of the worm gear, and a moving structure fixedly installed inside the connecting plate for driving the lifting plate to move laterally.

[0008] By adopting the above technical solution, stones and debris in the water can be dumped to the side of the drainage ditch, thereby reducing the phenomenon that the water flow speed is slowed down due to the accumulation of stones and debris in front of the filter plate, which affects the purification efficiency of the wetland.

[0009] Furthermore, the shift plate is a hollow rectangle, and two through holes are provided at both the top and bottom ends of the shift plate for two lead screws to pass through it.

[0010] Using the above technical solution, the lead screw can move within the sliding plate.

[0011] Furthermore, the threaded cylinder is a rectangle that is hollow inside and missing at both the top and bottom ends, and the threaded cylinder is threaded to the outer surface of the lead screw.

[0014] Using the above technical solution, the lifting plate can be moved left and right so that it can be moved from the top of the exhaust duct to the side of the drainage duct.

[0015] Furthermore, a threaded hole is provided on the right side of the threaded block for threaded connection with the screw, the left end of the screw is rotatably connected to the left wall of the connecting plate cavity via a bearing, and the second motor is fixed to the right wall of the connecting plate cavity.

[0016] By adopting the above technical solution, the screw can drive the threaded block to move through the threaded hole.

[0017] Furthermore, the front end of the connecting plate is provided with a sliding hole for the moving block to pass through its interior.

[0018] The above technical solution facilitates the connection between the moving block and the flipping structure.

[0019] Furthermore, the flipping structure includes a rotating block, a hidden groove, support rods fixedly installed around the rear end of the rotating block, and a micro motor fixedly installed on the rear wall of the inner cavity of the hidden groove.

[0020] By adopting the above technical solution, the lifting plate can be flipped over so that stones and debris located on the top of the lifting plate can be dumped, which can reduce the probability of workers entering the drainage ditch to clear the ditch.

[0021] Furthermore, the hidden groove is formed at the front end of the moving block, and a circular hole is formed at the rear end of the moving plate, with the rotating block fixed inside the circular hole.

[0022] The above technical solution allows the rotating block to be flipped by the lifting plate driven by the moving plate.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This farmland drainage channel water purification equipment, equipped with treatment components, can dump stones and debris in the water to the side of the drainage ditch. This reduces the phenomenon that the accumulation of stones and debris on the front side of the filter plate causes the water flow to slow down, thus affecting the purification efficiency of the wetland. It also reduces the probability of workers entering the drainage ditch to clear the ditch, ensuring the purification efficiency of the wetland. Attached Figure Description

The threaded cylinder 42 is threaded to the outer surface of the lead screw 41, and the through hole corresponds to the threaded cylinder 42. The diameter of the threaded cylinder 42 is larger than that of the through hole, so as to restrict the rotation of the threaded cylinder 42 within the moving plate 4. And through its threaded connection with the lead screw 41, the two lead screws 41 can drive the lifting plate 2 to move up and down.

[0036] Furthermore, the first motor 44 is fixed to the left wall of the inner cavity of the moving plate 4, and the right end of the worm gear 45 is rotatably connected to the right wall of the inner cavity of the moving plate 4 through a bearing.

[0037] Please see Figures 3 to 4 The moving structure in this embodiment includes a second motor 46, a moving block 49, a screw 47 fixedly installed at the output end of the second motor 46, a threaded block 48 fixedly installed at the rear end of the moving block 49, and a flipping structure fixedly installed at the front end of the moving block 49.

[0038] Secondly, a threaded hole is provided on the right side of the threaded block 48 so that it can be threadedly connected to the screw 47, so that the screw 47 can drive the threaded block 48 to move left and right. The left end of the screw 47 is rotatably connected to the left wall of the inner cavity of the connecting plate 3 through a bearing, and the second motor 46 is fixed to the right wall of the inner cavity of the connecting plate 3.

[0039] In addition, the front end of the connecting plate 3 is provided with a sliding hole for the moving block 49 to pass through its interior so that the moving block 49 can be connected to the placement structure and the moving plate 4 can be moved left and right by the flipping structure.

[0042] Furthermore, the front wall of the moving block 49 is provided with an annular groove, and four support rods 411 are slidably connected in the annular groove so as to increase the connection between the rotating block 410 and the moving block 49.

[0043] It should be noted that all electronic components mentioned in this article are commonly known in the prior art, and all electrical components mentioned in this article are connected to the controller and power supply. The control method of this embodiment is controlled by the controller, and the control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also commonly known in the art, so this utility model will not explain the control method and circuit connection in detail.

[0044] The working principle of the above embodiments is as follows:

[0045] When in use, when farmland drainage water flows through filter plate 1 into wetland, filter plate 1 filters out impurities and stones in the water. The impurities and stones accumulate at the front end of filter plate 1 and are located at the top of lifting plate 2. The output end of the first motor 44 drives the worm 45 to rotate, so that the worm 45 meshes with the front side of the two worm gear sleeves 43. When the two worm gear sleeves 43 rotate, they can drive the threaded cylinder 42 to rotate. The two threaded cylinders 42 can be threadedly connected to the two lead screws 41, so that the two lead screws 41 can drive the lifting plate 2 to move upward, so that the lifting plate 2 gradually removes the impurities and stones from the water.

[0046] The output of the second motor 46 drives the screw 47 to rotate, causing the screw 47 to move the threaded block 48 to the left. This causes the threaded block 48 to move the flipping structure to the left via the moving block 49, which in turn causes the moving plate 4 to move the lifting plate 2 to the left via the two lead screws 41, allowing the lifting plate 2 to be moved to the side of the drainage ditch. The output of the micro motor 412 then drives the rotating block 410 to rotate, causing the rotating block 410 to flip the moving plate 4 downward. This causes the moving plate 4 to flip the lifting plate 2 downward via the two lead screws 41, allowing the lifting plate 2 to dump the stones and debris on its top to the side of the drainage ditch. This reduces the phenomenon where the accumulation of stones and debris on the front side of the filter plate 1 causes the water flow to slow down, thus affecting the water purification efficiency of the wetland.
