Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology for planting, specifically a drip irrigation anti-clogging filter for dragon's blood. Background Technology

[0002] Dragon's blood is a commonly used traditional Chinese medicine with the effects of promoting blood circulation, removing blood stasis, stopping bleeding, promoting digestion, eliminating dampness and relieving pain. It has a pungent and bitter taste and is slightly warm in nature. It enters the liver, spleen and stomach meridians. At present, modern pharmacological research on dragon's blood mainly focuses on the effects of its chemical components (such as tannins, flavonoids, phenolic acids, etc.). Dragon's blood is mainly produced in Sichuan, Yunnan and Guizhou provinces in my country. These regions have cool climates, fertile and deep soils, and good drainage, which meet the growth habits of dragon's blood, which prefers cool and sunny conditions. It is also distributed in northeastern India and northern Thailand.

[0003] To ensure efficient water use during the cultivation of *Dracaena sanderiana*, drip irrigation is commonly used. Drip irrigation slowly infiltrates the soil in a dripping manner, achieving high-efficiency water resource utilization. However, if the water source contains impurities and sand, these can clog the drippers, preventing water from flowing out. Most systems install filters at the drip line input to filter out sand and impurities, reducing the likelihood of clogging. While filters can intercept sand and impurities, existing filters accumulate excessive sand and impurities over time, causing blockages and hindering water flow. This necessitates disassembling the filter and cleaning the internal screen, which is time-consuming and requires removing many fasteners, reducing the efficiency of drip irrigation. Therefore, we provide a *Dracaena sanderiana* drip irrigation anti-clogging filter to solve these problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-6 As shown, this utility model provides a technical solution: a drip irrigation anti-clogging filter for dragon's blood, including a housing 1 and a filter screen 2. The outer surface of the housing 1 is connected to an inlet pipe 3 and an outlet pipe 4, and the inlet pipe 3 and the outlet pipe 4 are symmetrical. The filter screen 2 is installed inside the housing 1, and the bottom end of the filter screen 2 is connected to a drain pipe 5. The housing 1 provides support for the components to be mounted. Water is input into the housing 1 through the inlet pipe 3, and the filtered water is discharged through the outlet pipe 4. The filter screen 2 filters the water input into the housing 1, intercepting sand and gravel impurities inside.

[0030] The inner wall of the filter screen 2 is connected to a first support frame 6, and the inner wall of the drain pipe 5 is connected to a second support frame 7. The inner walls of the first support frame 6 and the second support frame 7 are rotatably connected to a rotating shaft 8. The outer surface of the rotating shaft 8 is connected to a roller frame 9, and the outer surface of the roller frame 9 is connected to a brush 10. The outer surface of the roller frame 9 is also connected to a scraper 11. The outer surfaces of the brush 10 and the scraper 11 are in contact with the inner wall of the filter screen 2. The first support frame 6 and the second support frame 7 provide support at both ends of the rotating shaft 8 to maintain the stability of the rotating shaft 8. The rotation of the rotating shaft 8 provides power for the rotation of the roller frame 9. When the roller frame 9 rotates, it drives the brush 10 and the scraper 11 to rotate simultaneously. After the scraper 11 and the brush 10 rotate, they clean away the sand and impurities adhering to the inside of the filter screen 2. The cleaned sand and impurities are discharged from the inside of the filter screen 2 through the drain pipe 5, maintaining the cleanliness of the inside of the filter screen 2.

[0031] The bottom end of the housing 1 is connected to a threaded seat 13, and the outer surface of the threaded seat 13 is threaded to a cap 14. The threaded seat 13 provides support for the cap 14, maintains the stability of the cap 14, and facilitates the disassembly and assembly of the cap 14.

[0032] A cover plate 12 is installed at the top of the housing 1. The cover plate 12 is located on one side of the housing 1 and contacts the top of the filter screen 2. A first sealing ring 15 is installed at the top of the housing 1. The first sealing ring 15 is made of rubber. The outer surface of the first sealing ring 15 contacts the cover plate 12 on one side of the housing 1. The first sealing ring 15 fills the gap between the housing 1 and the cover plate 12, improves the sealing between the cover plate 12 and the housing 1, and prevents water from leaking from the gap between the cover plate 12 and the housing 1.

[0033] There are four brushes 10 and four scrapers 11 arranged in a circular array. The brushes 10 clean the sand and impurities adhering to the inner wall of the filter screen 2, and the scrapers 11 scrape off the more stubborn sand and impurities.

[0034] The inner side of the housing 1 is provided with a plurality of positioning holes 16, and the plurality of positioning holes 16 are arranged in a circular array. One side of the filter screen 2 is connected with a number of positioning pins 17 equal to the number of positioning holes 16. The outer surface of the positioning pins 17 contacts the inner wall of the positioning holes 16, and the positioning holes 16 provide resistance to the positioning pins 17. The positioning pins 17 transmit the resistance to the filter screen 2, thereby maintaining the stability of the filter screen 2.

[0035] The threaded seat 13 is located on one side of the cap 14 and is connected to a second sealing ring 18. The second sealing ring 18 is made of rubber and its outer surface is in contact with the inner wall of the cap 14. The second sealing ring 18 increases the sealing between the cap 14 and the threaded seat 13 and prevents water from leaking from the gap between the threaded seat 13 and the cap 14.

[0036] The inner side of the cap 14 is connected to a drain pipe 19, and a valve 20 is installed at the end of the drain pipe 19. When installing the cap 14, the valve 20 is opened to allow the sewage pipe 5 to discharge through the drain pipe 19, thereby reducing the pressure of the water discharged from the sewage pipe 5 on the cap 14. After the cap 14 is installed in place, the valve 20 is closed.

[0037] The bottom end of the rotating shaft 8 is connected to a four-corner head 21, and the outer surface of the cap 14 is connected to a four-corner sleeve 22. The four-corner sleeve 22 is adapted to the four-corner head 21. The rotating shaft 8 receives power through the four-corner head 21, making it easy for you to rotate the rotating shaft 8. The four-corner sleeve 22 is wrapped around the outside of the four-corner head 21. The cap 14 and the drain pipe 19 make it easy for your hand to contact and rotate the four-corner sleeve 22. Thus, the four-corner sleeve 22 drives the rotating shaft 8 to rotate through the four-corner head 21.

[0038] Working principle: When a lot of sand and impurities are stuck inside the filter screen 2, first unscrew the cap 14, then connect the four corner sleeves 22 and the four corner heads 21 together. Then rotate the cap 14 to drive the rotating shaft 8 to rotate. At the same time, the rotating shaft 8 drives the brush 10 and scraper 11 to rotate through the roller frame 9. The brush 10 and scraper 11 scrape the sand and impurities from the inner wall of the filter screen 2. Then, driven by the water flow, the sand and impurities are discharged from the drain port. After the sand and impurities are cleaned, tighten the cap 14 back onto the threaded seat 13. Before installing the cap 14, open the valve 20 to allow the water discharged from the drain pipe 5 to be discharged through the drain pipe 19, reducing the impact of the water flowing out of the drain pipe 5 on the cap 14.
