Moreover, it can automatically scrape the inner and outer sides of the filter screen according to the water flow, effectively preventing foreign objects from adhering to the filter screen, thereby solving the aforementioned technical problems.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an anti-clogging and protective structure for an irrigation water pump head, which includes an installation ring installed at the water inlet of the water pump body, a filter screen shell welded to the right side of the installation ring, a rotating ring rotatably connected to the inner side of the installation ring, an inner support scraper frame fixedly connected to the right side of the rotating ring and fitting against the inner side of the filter screen shell, a connecting column penetrating to the right side of the filter screen shell fixedly connected to the right side of the inner support scraper frame, a conical block fixedly connected to the end of the connecting column, and three outer scrapers fixedly connected to the outer surface of the filter screen shell in a circular array on the surface of the conical block.
[0005] Preferably, the surface of the cone block is provided with three guide grooves.
[0006] Preferably, the inner side of the inner support scraper frame is fixedly connected with multiple inclined guide vanes.
[0007] Preferably, the mounting ring has an annular groove on its left side, and the rotating ring is rotatably connected to the inner cavity of the annular groove.
[0008] Preferably, the right side of the filter shell has a perforation for the connecting post to pass through and rotate.
[0009] Preferably, the mounting ring has four screw holes, and the mounting ring is threaded onto the flange at the inlet of the water pump body by screws passing through the screw holes.
[0010] The beneficial effects of this utility model are:
[0011] 1. This utility model involves fitting a water inlet pipe onto a filter screen shell and connecting it to the inlet of a water pump body via a flange. When the water pump body is in operation, water enters the water pump body through the water inlet pipe. During this process, the water flow passes through the filter screen shell to prevent foreign objects from entering the water pump body. The water flow impacts the arc-shaped guide groove and guide vanes, causing the inner support scraper frame and outer scraper to rotate, scraping the inner and outer sides of the filter screen shell to prevent foreign objects from adhering to the filter screen and affecting the water inlet efficiency of the water pump body.
[0012] 2. By setting the annular groove, this utility model can install the rotating ring and the inner support scraper frame from the left side of the mounting ring on the inner side of the filter screen shell, and the annular groove provides space for the rotation of the rotating ring.

[0019] In the following description, embodiments of the irrigation water pump head anti-clogging protection structure of this utility model will be described with reference to the accompanying drawings.
[0020] Figure 1-3This invention illustrates an embodiment of an anti-clogging protection structure for an irrigation water pump head, comprising a mounting ring 2 installed at the inlet of a water pump body 1. The mounting ring 2 has four screw holes 13. The mounting ring 2 is threaded onto the flange at the inlet of the water pump body 1 by screws passing through the screw holes 13. A filter screen shell 3 is welded to the right side of the mounting ring 2. A rotating ring 4 is rotatably connected to the inner side of the mounting ring 2. An annular groove 11 is provided on the left side of the mounting ring 2. The rotating ring 4 is rotatably connected to the inner cavity of the annular groove 11. The annular groove 11 allows the rotating ring 4 and the inner support scraper bracket 5 to be mounted from the left side of the mounting ring 2 onto the filter screen shell. Inside the filter housing 3, and the annular groove 11 provides space for the rotation of the rotating ring 4. The right side of the rotating ring 4 is fixedly connected to an inner support scraper frame 5 that fits into the inner side of the filter housing 3. Multiple inclined guide vanes 10 are fixedly connected to the inner side of the inner support scraper frame 5. A connecting post 6 that penetrates to the right side of the filter housing 3 is fixedly connected to the right side of the inner support scraper frame 5. A through hole 12 is opened on the right side of the filter housing 3 for the connecting post 6 to pass through and rotate. A cone block 7 is fixedly connected to the end of the connecting post 6. Three guide grooves are opened on the surface of the cone block 7. Three outer scrapers 8 that fit into the outer surface of the filter housing 3 are fixedly connected to the surface of the cone block 7 in an annular array.
[0021] Working principle: When using this utility model, the user connects the water inlet pipe to the filter screen shell 3 and the water inlet of the water pump body 1 through the flange. The water pump body 1 is working, and water enters the water pump body 1 through the water inlet pipe. During this process, the water flow will be filtered by the filter screen shell 3 to prevent foreign objects from entering the water pump body 1. The water flow impact will disperse the water flow on the cone block 7. The dispersed water flow enters the arc-shaped guide groove 9, and the water flow will cause the cone block 7 to rotate. The cone block 7 will drive the outer scraper 8, the connecting column 6 and the inner support scraper frame 5 to rotate. The guide blades 10 on the inner support scraper frame 5 will also exert a force on the rotation of the inner support scraper frame 5 as the water flow passes by. The inner support scraper frame 5 and the outer scraper 8 scrape the inner and outer sides of the filter screen shell 3 to prevent foreign objects from adhering to the filter screen and affecting the water inlet efficiency of the water pump body 1.
[0022] In summary, the anti-clogging protection structure of this irrigation water pump head works by fitting the water inlet pipe onto the filter screen shell 3 and connecting it to the inlet of the water pump body 1 via a flange. When the water pump body 1 is working, water enters the water pump body 1 through the water inlet pipe. During this process, the water flow is filtered by the filter screen shell 3, preventing foreign objects from entering the water pump body 1. The flow of water impacts the arc-shaped guide groove 9 and the guide blades 10, causing the inner support scraper frame 5 and the outer scraper 8 to rotate, scraping the inner and outer sides of the filter screen shell 3 to prevent foreign objects from adhering to the filter screen and affecting the water pump body 1's water intake efficiency.
