Description

Technical Field

[0001] This utility model relates to a filtration device, and more particularly to a farmland irrigation filtration device. Background Technology

[0002] Farmland irrigation is a method of supplying water to farmland by artificial means. It not only meets the water needs of crops but also regulates the soil's air, heat, and nutrient conditions. During farmland irrigation, water pumps are typically used to pump water from irrigation ditches to the farmland for surface irrigation.

[0003] However, nowadays, when using water pumps for irrigation, the pumping pipes are directly immersed in the irrigation ditches. Over time, and due to natural environmental factors (such as rainwater erosion and plant growth), these ditches accumulate large amounts of weeds, household waste, and other debris. This debris can clog the pumping pipes and pumps, affecting water flow and irrigation efficiency.

[0004] To address the above issues, we have developed a farmland irrigation filtration device that filters irrigation water. Utility Model Content

[0005] The purpose of this utility model is to overcome the problem that water pipes and pumps in the prior art are easily blocked by debris in irrigation ditches, and to provide a farmland irrigation filtration device.

[0006] The purpose of this utility model is achieved as follows:

[0007] A filter assembly includes a middle frame, which is a box structure open at the front and back. A barrier grid is provided on the front side of the middle frame. The barrier grid has a conical structure with a straight middle section. A plurality of filter holes are provided on each side of the barrier grid. A fixing plate is installed on the inner side of the middle frame. A plurality of fixing holes are provided through the surface of the fixing plate.

[0008] Furthermore, a rubber ring is provided inside the fixing hole.

[0009] Furthermore, the diameter of the fixing holes increases sequentially from left to right.

[0010] Furthermore, a plurality of barrier frames are provided on the front side of the middle frame.

[0011] A farmland irrigation filtration device, comprising a top plate;

[0012] Support components are installed on both sides of the top plate;

[0013] The lifting assembly is installed in the middle of the top plate;

[0014] The filter assembly is installed at the output end of the lifting assembly.

[0015] Furthermore, the support assembly includes side plates, a sliding plate, a support base, and fastening bolts. The side plates are inclined on both sides of the top plate, and a fastening groove is formed through the middle of the side plate along its length. The sliding plate has a U-shaped structure, and the side plates are located inside the sliding plate and slidably connected to it. The fastening bolts are screwed through the middle of the sliding plate and pass through the fastening groove. The support base is provided on the outer side of the sliding plate.

[0016] Furthermore, the support base includes a connecting rod, ear plates, and a contact plate. The connecting rod is disposed on the outer side of the slide plate, and the two ends of the connecting rod are rotatably connected to the ear plates. The contact plate is disposed between the two ear plates.

[0017] Furthermore, a friction pad is provided on the outer side of the contact plate.

[0018] Furthermore, the lifting assembly includes a lifting rod, a vertical plate, and a handle. The lifting rod is screwed through the middle of the top plate, the handle is provided at the top of the lifting rod, the bottom of the lifting rod is rotatably connected to the middle frame, the vertical plate is provided on both sides of the bottom surface of the top plate, and the inner side of the vertical plate is slidably connected to the middle frame.

[0019] Advantages of this utility model:

[0020] In this technical solution, when the water pump is drawing water, the pump's suction pipe is inserted into the fixing hole of the fixing plate. Then, the filter assembly is lowered via a lifting component, submerging it below the water surface of the irrigation ditch. At this point, the water pump can begin pumping water for irrigation. A barrier screen isolates debris from the irrigation ditch, while water passes through filter holes on its surface, flows into the barrier screen, and is then drawn by the suction pipe. This prevents debris from clogging the suction pipe and the water pump. Filtration effectively removes these impurities, ensuring clean and impurity-free irrigation water, thereby protecting irrigation equipment and pipes, extending their service life, reducing maintenance costs and time losses caused by blockages, and significantly improving irrigation efficiency.

[0029] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0030] This application provides a farmland irrigation filtration device.

[0031] Example 1, such as Figure 1-4 As shown.

[0032] A farmland irrigation filtration device includes a top plate 1, which is a rectangular plate structure.

[0033] An agricultural irrigation filtration device further includes a support assembly 2, which is installed on both sides of the top plate 1 to fix the entire device and fix it inside the irrigation ditch.

[0034] Further, the support assembly 2 includes a vertical plate 21, a sliding plate 22, a support base 23, and fastening bolts 24. The side plates 21 are inclined on both sides of the top plate 1, with the angle between the side plates 21 and the top plate 1 preferably being 135°. A fastening groove 211 is formed through the middle of the side plate 21 along its length. The sliding plate 22 has a U-shaped structure, and the side plate 21 is located inside the sliding plate 22 and slidably connected to it. The fastening bolts 24 are screwed through the middle of the sliding plate 22, passing through the fastening groove 211. Tightening the fastening nut secures the sliding plate 22 and the side plate 21 together through the friction between them. Loosening the fastening nut allows adjustment of the position of the sliding plate 22 according to the width of the irrigation ditch. The support base 23 is provided on the outer side of the sliding plate 22, contacting the inner wall of the irrigation ditch to fix the entire device. Adjust the position of the slide plate 22, and then place the support base 23 against the inner wall of the irrigation ditch to fix the entire equipment.

[0035] The support base 23 includes a connecting rod 231, ear plates 232, and a contact plate 233. The connecting rod 231 is disposed on the outer side of the sliding plate 22, and the two ends of the connecting rod 231 are rotatably connected to the ear plates 232. The contact plate 233 is disposed between the two ear plates 232. A friction pad 234 is disposed on the outer side of the contact plate 233. The friction pad 234 increases the friction between the support base 23 and the side wall of the irrigation ditch, making the overall equipment more securely fixed.

[0036] A farmland irrigation filtration device includes a lifting component 3 installed in the middle of the top plate 1, which adjusts the height of the filtration component 4 so that it is submerged below the water surface of the ditch.

[0037] Furthermore, the lifting assembly 3 includes a lifting rod 31, a vertical plate 32, and a handle 33. The lifting rod 31 is screwed through the middle of the top plate 1. The handle 33 is provided at the top of the lifting rod 31, and the bottom of the lifting rod 31 is rotatably connected to the middle frame 41. The vertical plates 32 are respectively provided on both sides of the bottom surface of the top plate 1, and the inner side of the vertical plates 32 is slidably connected to the middle frame 41. By turning the handle 33, the filter assembly 4 can be moved up and down through the lifting rod, causing it to be submerged below the water surface in the ditch.

[0038] A farmland irrigation filtration device includes a filter component 4, which is installed at the output end of the lifting component 3 to filter irrigation water and prevent the irrigation equipment from being blocked or damaged.

[0039] The filter assembly 4 includes a middle frame 41, which is a box structure open at the front and back. A barrier grille 42 is provided on the front side of the middle frame 41. The barrier grille 42 has a conical structure with a straight section in the middle. Each side of the barrier grille 42 has a plurality of filter holes 421. The conical shape of the barrier grille 42 prevents debris from accumulating on its surface. Under the impact of water flow, debris will drift to both sides of the barrier grille 42, preventing it from becoming clogged.

[0040] A fixing plate 43 is installed on the inner side of the middle frame 41, and a plurality of fixing holes 431 are formed through the surface of the fixing plate 43. A rubber ring 44 is provided inside each fixing hole 431, and the diameter of the fixing holes 431 increases sequentially from left to right. The pump pipe of irrigation tools such as water pumps is directly inserted into the fixing holes 431 for fixation. The fixing holes 431 with different diameters can accommodate the pump pipes of various types of irrigation tools.

[0041] Several barrier frames 45 are provided on the front side of the middle frame 41. Each barrier frame 45 has a U-shaped structure, and three barrier frames 45 are provided at equal intervals on the front side of the middle frame 41. The barrier frames 45 can intercept large debris and gravel, preventing them from directly impacting the surface of the barrier grid 42 and causing it to deform or become blocked.

[0042] When using this utility model:

[0043] 1. Adjust the support assembly according to the width of the irrigation ditch. Loosen the fastening nut and adjust the extension length of the sliding plate so that the support base can be stably supported on the inner surface of the ditch. After adjustment, tighten the fastening nut.
