Description

Technical Field

[0001] This utility model belongs to the field of agricultural water conservancy technology, specifically, it relates to a pipeline filter for irrigation. Background Technology

[0002] The nozzles, drippers, pipes, and other components in an irrigation system are very delicate and are easily clogged and worn by impurities. Using filters can effectively reduce clogging and damage to these components and extend the service life of the irrigation system.

[0003] The prior art discloses a pipeline filter for agricultural irrigation (CN221788420U), including an inlet pipe, a third filter assembly, and an outlet pipe. A first filter assembly is detachably mounted at one end of the inlet pipe, and a second filter assembly is detachably mounted at the other end. The third filter assembly has an internal baffle mesh with a reinforcing frame on its front. A filter layer is movably mounted inside the third filter assembly. This invention, by including a third filter assembly and connecting the first, second, and third filter assemblies via a threaded assembly, allows for adjusting the number of filter assemblies based on the amount of impurities in the water flow. The reinforcing frame increases the support strength of the baffle mesh. The multiple filter layers within the various filter assemblies enable multi-layer filtration of impurities in the irrigation water flow, effectively improving the filtration efficiency.

[0004] Research revealed that existing technologies lack measures for collecting impurities, leading to the accumulation of scale and dirt inside the filter components after prolonged use. This affects both filtration efficiency and water quality. Furthermore, existing technologies require disassembly after use to remove dirt, which is cumbersome and frequent disassembly can compromise the device's airtightness, causing leaks. Finally, disassembly requires disconnecting the water pipes at both ends, a relatively slow process that delays cleaning and maintenance, ultimately hindering filtration efficiency.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0034] A pipeline filter for irrigation, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, it includes a connecting pipe 10, a support base 11 fixedly disposed at the bottom of the connecting pipe 10, and a sleeve 12 movably disposed inside the connecting pipe 10; a pop-out structure, movably disposed between the connecting pipe 10 and the support base 11, the pop-out structure including a lifting block 13 and a plug 17, the lifting block 13 movably disposed between the connecting pipe 10 and the support base 11, the plug 17 elastically disposed inside one side of the lifting block 13, and the plug 17 sliding within the wall of the support base 11; and a filter assembly. The filter assembly is movably disposed within the sleeve 12. The filter assembly includes a gear frame 21, a gear 22, a primary filter tube 24, a collection box 25, an inner filter box 27, a fine filter box 29, and a fixing rod 31. The gear frame 21 and the gear 22 are both rotatably disposed inside the sleeve 12. The fixing rod 31 is fixedly disposed on one side of the gear frame 21. The primary filter tube 24, the inner filter box 27, and the fine filter box 29 are all snapped into the sleeve 12. The collection box 25 is snapped into the fixing rod 31 and rotates within the sleeve 12.

[0035] Specifically, this device uses a pop-out structure to control the position of the filter assembly by connecting the plug 17 and the lifting block 13. When disassembly is required, pressing the plug 17 will allow the lifting block 13 to move away from the restriction and pop out, achieving quick disassembly and speeding up the cleaning and maintenance time of the device, thereby improving the filtration efficiency to a certain extent. By setting the filter assembly, the gear 22 meshes with the gear frame 21 to rotate, and the gear frame 21 drives the collection box 25 to scrape the surface of the primary filter box 24, the inner filter box 27 and the fine filter box 29. The operation is simple and the device can be cleaned without disassembling it. At the same time, a rubber ring for waterproof sealing is set at the connection between the gear frame 21 and the sleeve 12. The rubber ring assists the rotation of the gear frame 21 while achieving waterproofing, avoiding water leakage.

[0036] like Figure 2 and Figure 3 As shown, the connecting pipe 10 is a cylindrical structure, the support base 11 is a box structure, the top surface of the lifting block 13 has an arc surface, the lifting block 13 corresponds to the shape inside the support base 11, and a support spring 18 is fixedly installed between the lifting block 13 and the support base 11, and the support base 11 is elastically connected to the lifting block 13 through the support spring 18; Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a slide rail 14 with an L-shaped cross section is provided on the inner surface of the support base 11, and a telescopic cavity 19 is provided on one side of the lifting block 13. The plug 17 slides in the telescopic cavity 19, and a resisting spring 16 is fixedly provided between the plug 17 and the telescopic cavity 19. The plug 17 is elastically connected to the telescopic cavity 19 through the resisting spring 16. The plug 17 slides in the slide rail 14, and the support base 11 locks and limits the plug 17 through the slide rail 14.

[0037] Specifically, firstly, the entire lifting block 13 is made of rubber, which provides greater tension. The rubber material also ensures better airtightness between the connecting pipe 10 and the support seat 11. When the sleeve 12 is not installed inside the connecting pipe 10, the lifting block 13 protrudes slightly inside the connecting pipe 10 under the support of the support spring 18. At the same time, the plug 17 slides up and down in the vertical part of the slide rail 14. At this time, the resisting spring 16 is in a compressed state. When the sleeve 12 is inserted into the connecting pipe 10, the bottom of the sleeve 12 is located on the arc surface of the lifting block 13. Simultaneously, the lifting block 13 penetrates into the support seat 11. At this time, the support spring 18 is in a compressed state. Furthermore, the plug 17 slides to the bottom horizontal part of the slide rail 14. Under the rebound of the resisting spring 16, the plug 17 is inserted into the horizontal part of the slide rail 14 to limit the lifting block 13.

[0038] like Figure 2 and Figure 6 As shown, a bayonet 15 is provided at the top of the connecting pipe 10, and the sleeve 12 corresponds to the shape of the bayonet 15. The sleeve 12 is snapped into the bayonet 15, and a sealing ring is provided between the sleeve 12 and the bayonet 15 to prevent water leakage; Figure 4 As shown, a rotating opening 20 and an annular groove 23 are provided inside one end of the sleeve 12. The rotating opening 20 and the annular groove 23 are connected. The gear 22 is rotatably disposed in the rotating opening 20, and the gear frame 21 is rotatably disposed in the annular groove 23. The gear 22 drives the meshing of the annular groove 23.

[0039] Specifically, a rubber ring is provided at the junction of the gear carrier 21 and the ring groove 23. The special material of the rubber is used to seal the gap between the two, which increases the airtightness and also assists the gear carrier 21 in rotating in the ring groove 23. At the same time, the maximum diameter of the gear ring is less than or equal to the diameter of the ring groove 23. When the gear 22 is turned, the gear 22 meshes with the gear ring, and the gear carrier 21 rotates in the ring groove 23.

[0040] like Figure 5 and Figure 6 As shown, the primary filter tube 24, the inner filter box 27, and the fine filter box 29 are similar in shape but different in specifications. The cross-sectional shape of all three is similar to an I-beam. All three are snap-fitted into place within the sleeve 12. Figure 5 , Figure 6 and Figure 7 As shown, the gear frame 21 consists of a gear ring and a cross-shaped bracket. A cross-shaped fixing rod 31 is fixedly installed on one side of the cross-shaped bracket. The centers of the primary filter tube 24, the inner filter box 27, and the fine filter box 29 are all movably penetrated by the same fixing rod 31. Multiple locking posts 28 are engaged on the fixing rod 31. Two collection boxes 25 are provided on the curved surface of each locking post 28, and the two collection boxes 25 are symmetrically arranged on both sides of the locking post 28. Figure 5 and Figure 6 As shown, the collection box 25 is a fan-shaped box, and an L-shaped scraper 26 is provided on one side of the collection box 25; as Figure 5 As shown, a threaded post 32 is fixedly installed at the end of the fixing rod 31 away from the gear frame 21. The threaded post 32 passes through the locking post 28. A limit head 30 is threaded on the threaded post 32. The fixing rod 31 locks and limits the primary filter tube 24, the inner filter box 27, the fine filter box 29 and all the locking posts 28 through the limit head 30.

[0041] Specifically, firstly, a locking post 28 and two collection boxes 25 form a bow-shaped storage box. Then, the filter components are placed in the following order: gear frame 21, fixing rod 31, one storage box, primary filter box 24, two storage boxes, inner filter box 27, two storage boxes, fine filter box 29, one storage box, and limiting head 30. The primary filter box 24, inner filter box 27, and fine filter box 29 are directly fitted onto the fixing rod 31. The locking post 28 in the storage box has a cross-shaped hole corresponding to the shape of the fixing rod 31. During installation, the cross-shaped hole needs to be aligned with the fixing rod 31. After installation, tighten the limiting head 30 to secure all the above structures. When in use, when gear 22 drives gear frame 21 to rotate, all the collection boxes will rotate synchronously under the drive of locking post 28. The primary filter tube 24, inner filter box 27, and fine filter box 29 are all composed of a ring and a filter plate. The length of collection box 25 corresponds exactly to the distance between the filter plate and the side of the ring. When the collection box rotates, the scraping edge 26 of collection box 25 will contact the surface of the filter plate and scrape. Therefore, during installation, it is important to ensure that the scraping edge 26 is in close contact with the side of the filter plate.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
