Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment technology, and in particular to a PE pre-perforated water hose. Background Technology

[0002] PE water hoses are a type of flexible hose used for transporting fluids, primarily for irrigating farmland, orchards, vegetable gardens, lawns, and landscaping. They are mainly made of polyethylene (PE). Existing PE water hoses have pre-drilled holes with ultrasonically welded threaded seats at these holes, allowing connection to drip irrigation tape or micro-sprinkler tape via fittings. Installation is convenient and provides good irrigation results. However, during use, the irrigation water inside the PE water hose is prone to contamination with mud, sand, and impurities, causing blockages in the drip irrigation tape or micro-sprinkler tape, affecting irrigation efficiency, requiring frequent cleaning by staff, reducing irrigation efficiency, and increasing manpower burden. Utility Model Content

[0003] In order to overcome the above-mentioned defects in the prior art, this utility model provides a PE pre-perforated water hose.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a PE pre-drilled hole water hose, including a water hose body, a plurality of pre-drilled holes are arranged at intervals on the water hose body, an externally inlaid threaded seat is ultrasonically welded at the pre-drilled hole, an internal thread is provided at the through hole of the threaded seat, the threaded seat is connected to the first external thread of the connecting pipe through the internal thread, the upper end of the connecting pipe is provided with the second external thread of the connecting pipe fitting, the end of the connecting pipe is provided with the filter assembly, and the inside of the connecting pipe is provided with the cleaning assembly.

[0005] Furthermore, a limiting ring is provided between the first external thread and the second thread of the connecting pipe.

[0006] Furthermore, the filter assembly includes a primary filter and a secondary filter. The primary filter is fixedly connected to the end of the connecting pipe, and the secondary filter is disposed on the inner wall of the connecting pipe.

[0007] Furthermore, the primary filter screen is cylindrical with an inclined bottom. The bottom of the primary filter screen is inclined upwards towards the inner wall of the water belt body on the side closest to the water flow direction. The secondary filter screen is a circular plane.

[0008] Furthermore, the cleaning assembly includes an impeller, which is disposed inside the connecting pipe via an mounting ring. The impeller shaft is fixedly connected to the end of a connecting rod, and the other end of the connecting rod is connected to a scraper. The scraper is disposed between the primary filter and the secondary filter, and the scraper abuts against the secondary filter.

[0009] The beneficial effects of this utility model are as follows: In this utility model design, the primary filter screen filters large particles of mud and sand and impurities. The inclined bottom surface can prevent impurities from adhering to the filter screen due to water flow pressure and clogging the water flow. At the same time, it reduces the impact of water flow on the primary filter screen and extends its service life. The secondary filter screen is used to filter fine impurities and particles. The water flow drives the scraper to rotate through the impeller and connecting rod, which scrapes away the impurities at the secondary filter screen. The impurities are then transported forward through the primary filter screen in the water belt body by the action of the water flow in the main body, avoiding clogging of the secondary filter screen and affecting the irrigation effect. It also reduces the maintenance frequency. When cleaning is required, the staff can easily maintain and replace it by unscrewing the connecting pipe. Attached Figure Description

[0015] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0016] like Figures 1 to 3 As shown, a PE pre-drilled hole water hose includes a hose body 1 with multiple pre-drilled holes spaced apart on the hose body 1. An externally threaded seat 2 is ultrasonically welded to each pre-drilled hole. The threaded seat 2 has an internal thread at its through hole. The threaded seat 2 is connected to the first external thread of a connecting pipe 3 through the internal thread. The upper end of the connecting pipe 3 has a second external thread for connecting pipe fittings. The end of the connecting pipe 3 has a filter assembly. The interior of the connecting pipe 3 has a cleaning assembly.

[0017] A limiting ring 4 is provided between the first external thread and the second thread of the connecting pipe 3 to facilitate the connection of the connecting pipe 3 with the threaded seat 2 and the fitting.

[0018] like Figure 2 and Figure 3 As shown, the filter assembly includes a primary filter 5 and a secondary filter 6. The primary filter 5 is fixedly connected to the end of the connecting pipe 3, and the secondary filter 6 is disposed on the inner wall of the connecting pipe 3. The primary filter 5 is cylindrical with an inclined bottom. The bottom of the primary filter 5 is inclined to one side and upward towards the inner wall of the water belt body 1, near the water flow, to filter large particles of mud and impurities. The inclined bottom of the primary filter 5 can prevent impurities from adhering to the filter screen under the pressure of the water flow and clogging the water flow, while also reducing the impact of the water flow on the primary filter 5 and extending its service life. The secondary filter 6 is a circular plane used to filter fine impurities and particles.

[0019] The cleaning assembly includes an impeller 7, which is mounted inside the connecting pipe 3 via an mounting ring 8. The shaft of the impeller 7 is fixedly connected to the end of a connecting rod 9, and the other end of the connecting rod 9 is connected to a scraper 10. The scraper 10 is positioned between the primary filter screen 5 and the secondary filter screen 6, and it abuts against the secondary filter screen 6. Impurities after the first filtration adhere to the secondary filter screen 6. The water flow drives the impeller 7 to rotate, and the impeller 7 drives the scraper 10 to rotate via the connecting rod 9, scraping away the impurities at the secondary filter screen 6. The impurities leaving the secondary filter screen 6 are then transported forward through the primary filter screen 5 in the water hose body 1 by the water flow in the water hose body 1, thus avoiding clogging of the secondary filter screen 6, which would affect the irrigation effect and reduce the maintenance frequency. When cleaning is required, the operator can easily maintain and replace the filter by unscrewing the connecting pipe 3.

[0020] In use, the bottom of the primary filter screen 5 is inclined to one side and upwards towards the inner wall of the water hose body 1, filtering out large particles of mud and impurities. The inclined cut at the bottom of the primary filter screen 5 can prevent impurities from adhering to the filter screen due to water flow pressure and clogging the water flow. At the same time, it reduces the impact of water flow on the primary filter screen 5 and extends its service life. The secondary filter screen 6 is a circular plane used to filter fine impurities and particles. The impurities after the first filtration adhere to the secondary filter screen 6. The water flow drives the impeller 7 to rotate, and the impeller 7 drives the scraper 10 to rotate through the connecting rod 9, scraping off the impurities at the secondary filter screen 6. The impurities leaving the secondary filter screen 6 are carried forward in the water hose body 1 by the water flow in the water hose body 1 through the primary filter screen 5 again, avoiding clogging of the secondary filter screen 6, which would affect the irrigation effect and reduce the maintenance frequency. When cleaning is required, the staff can easily maintain and replace it by unscrewing the connecting pipe 3.
