Description

Technical Field

[0001] This utility model relates to the field of micro-irrigation technology, and in particular to a self-cleaning, anti-clogging wheat micro-irrigation device. Background Technology

[0002] Micro-irrigation is a localized irrigation technique that uses micro-irrigation equipment assembled into a micro-irrigation system to deliver pressurized water to the field, moistening the soil near the crop roots with a small flow rate through the irrigated area. Micro-irrigation can very conveniently apply water to the soil near each plant, often maintaining a low water stress to meet the crop's growth needs.

[0003] However, existing wheat micro-irrigation devices are prone to clogging and cannot properly irrigate wheat. The reason why wheat micro-irrigation devices are prone to clogging is that the water used to irrigate wheat contains a large number of impurities that can easily clog the outlet pipe. In addition, the water also contains a large number of calcium, magnesium and iron ions, which will adhere to the inside of the pipe and form scale after a long period of use, causing blockage. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a self-cleaning, anti-clogging wheat micro-irrigation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-cleaning and anti-clogging wheat micro-irrigation device, comprising: a water delivery pipe for the micro-irrigation device, a self-cleaning and anti-clogging mechanism at the top of the water delivery pipe, the self-cleaning and anti-clogging mechanism including a nozzle, a water delivery pipe at the bottom of the nozzle, an impeller at the top of the water delivery pipe, a connecting shaft at the bottom of the impeller, a sleeve on the outside of the connecting shaft, a circular seal on the outside of the sleeve, two water outlet pipes arranged in a mirror-symmetrical array on the inside of the circular seal, a scraper at the bottom of the connecting shaft, a sweeping rod at the bottom of the scraper, a sealing cover on the outside of the sweeping rod, a protective cover at the rear end of the sealing cover, a liquid storage tank at the rear end of the protective cover, and a circular fixing member at the bottom of the water delivery pipe.

[0022] As shown in Figures 1-6, this utility model provides a technical solution: a self-cleaning and anti-clogging wheat micro-irrigation device, comprising: a micro-irrigation device water delivery pipe 2, a self-cleaning and anti-clogging mechanism 1 at the top of the water delivery pipe 2, the self-cleaning and anti-clogging mechanism 1 including a nozzle 11, a water delivery pipe 191 at the bottom of the nozzle 11, an impeller 12 at the top of the water delivery pipe 191, a connecting shaft 15 at the bottom of the impeller 12, a sleeve 121 on the outside of the connecting shaft 15, a circular seal 14 on the outside of the sleeve 121, two water outlet pipes 13 arranged in a mirror-symmetrical array on the inside of the circular seal 14, a scraper 16 at the bottom of the connecting shaft 15, a sweeping rod 17 at the bottom of the scraper 16, a sealing cover 18 on the outside of the sweeping rod 17, and a protective cover 181 at the rear end of the sealing cover 18. A liquid storage tank 19 is provided at the rear end. A circular fixing member 192 is provided at the bottom end of the water supply pipe 191. Three equally spaced rings are provided at the top of the circular fixing member 192 on the water supply pipe 191. The bottom end of the water supply pipe 191 is fixedly connected to the top of the circular fixing member 192. The bottom end of the nozzle 11 is provided with threads, and the top of the water supply pipe 191 is provided with a corresponding groove. The nozzle 11 and the water supply pipe 191 are connected by threads. The bottom end of the circular fixing member 192 is provided with a corresponding slot hole for the water supply pipe 191. The bottom end of the impeller 12 is fixedly connected to the top of the connecting shaft 15. The connecting shaft 15 and the sleeve 121 are integral parts. The bottom end of the sleeve 121 is connected to the top of the circular seal 14 by a bolt thread. The inner side of the circular seal 14 is fixedly connected to the outer side of the outlet pipe 13. The bottom end of the connecting shaft 15 is connected to the top of the scraper 16 by a bolt thread. The bottom end of the scraper 16 is fixedly connected to the top of the sweeping rod 17. A sealing cover 18 is provided. A cylindrical protrusion is provided on the outer side, a torsion spring is provided on the inner side of the protective cover 181, a rubber stopper is provided on the top of the liquid storage tank 19, and a slot corresponding to the rubber stopper is provided on the top of the liquid storage tank 19. A pipe is provided on the water supply pipe 191 corresponding to the sealing cover 18. The outer side of the pipe is fixedly connected to the side of the protective cover 181 near the pipe. A slot corresponding to the pipe is provided at the bottom of the liquid storage tank 19. The bottom end of the pipe is fixedly connected to the bottom end of the liquid storage tank 19. The outer side of the sealing cover 18 is fixedly connected to the outer side of the pipe. The bottom end of the circular seal 14 is connected to the top of the water supply pipe 191 by bolt thread. A slot corresponding to the sleeve 121 is provided on the inner side of the circular seal 14.

[0023] In this embodiment, water is transported to the outlet pipe 13 via the water supply pipe 191. The water is sprayed out from the outlet pipe 13 and finally irrigates the wheat through the nozzle 11. When the water is sprayed out from the nozzle 11, it passes through the impeller 12, which drives the impeller 12 to rotate. The impeller 12 is fixedly connected to the connecting shaft 15. The rotation of the impeller 12 drives the connecting shaft 15 to rotate. The connecting shaft 15 is connected to the scraper 16 by bolt threads. The rotation of the connecting shaft 15 causes the scraper 16 at the bottom of the connecting shaft 15 to rotate, thereby scraping off the dirt attached to the bottom of the outlet pipe 13 and preventing dirt accumulation from clogging the outlet pipe 13. The sleeve 121 provided on the outside of the connecting shaft 15 allows the impeller 12, the connecting shaft 15, and the scraper 16 to rotate. The water supply pipe 191 rotates independently and is not affected by other parts. A circular seal 14 at the top of the water supply pipe 191 seals the pipe, allowing water to flow only from the outlet pipe 13. A sweeping rod 17 is located at the bottom of the scraper 16. A cylindrical protrusion is located on the outer side of the sealing cover 18. A torsion spring is located inside the protective cover 181, with its two ends connected to the protective cover 181 and the sealing cover 18, respectively. The protective cover 181 provides protection for the torsion spring, increasing its lifespan. Rotation of the scraper 16 rotates the sweeping rod 17, causing it to sweep the cylindrical protrusion and open the sealing cover 18. This generates a torsional force on the torsion spring. After the sweeping rod 17 passes the sealing cover 18, the external force disappears, and the torsion spring generates a rotational force, returning the sealing cover 18 to its original position. The storage tank 19... The interior contains a scale inhibitor containing sodium phosphate. When the sealing cap 18 is opened and closed, the scale inhibitor in the storage tank 19 flows into the water supply pipe 191 from the connected pipe by gravity. It then combines with calcium, magnesium and iron ions in the water to form soluble complexes, preventing them from crystallizing and precipitating. Through the interaction of the above parts, it can achieve the effects of self-cleaning and anti-clogging. Example

[0024] As shown in Figure 1-2, the water delivery pipe 2 of the micro-irrigation device includes a threaded fastener 21. A rolling bearing 22 is provided inside the threaded fastener 21, and a connection port 23 is provided outside the threaded fastener 21. A water inlet pipe 24 is provided at the bottom end of the connection port 23. A circular fastener 192 is fixedly connected to the inner side of the rolling bearing 22 on its outer side, and the threaded fastener 21 is fixedly connected to the outer side of the rolling bearing 22 on its inner side. A corresponding threaded fastener is provided inside the connection port 23. The threaded groove on the fixing part 21 is connected to the threaded fixing part 21 by the thread, and the bottom end of the fixing part 23 is fixedly connected to the top end of the water inlet pipe 24.

[0025] In this embodiment, the water delivery pipe 2 of the micro-irrigation device is connected to the body of the micro-irrigation device via a threaded fastener. The rolling bearing 22 on the inner side of 21 allows the force generated by the water flow from the irrigation nozzle to rotate the irrigation head, thereby creating a larger irrigation area, reducing the number of irrigation nozzles and lowering costs. The threaded fastener 21 is fixedly connected to the irrigation head, making it easier to disassemble and install the irrigation head.

[0026] Working principle: As shown in Figure 1-6, water flows from the micro-irrigation device body into the micro-irrigation device water delivery pipe 2, then through the groove at the bottom of the circular fixing part 192, and finally flows from the outlet to the nozzle 11. The water is sprayed out through the nozzle 11 to micro-irrigate the wheat. When the water flows out of the nozzle 11, it passes through the impeller 12. The force generated by the water flow drives the impeller 12 to rotate. The rotation of the impeller 12 drives the connecting shaft 15 and the scraper 16 to rotate. The rotation of the scraper 16 cleans the bottom of the outlet pipe 13, preventing dirt accumulation and blockage that could hinder normal micro-irrigation of the wheat. The sleeve 121 isolates the connecting shaft 15 to prevent other factors from affecting it. The rotation of the scraper 16 drives the sweeping bar 17 at the bottom to rotate, thereby sweeping the sealing cover 18 and causing it to... The sealing cover 18 can be opened. When it is opened, it will generate a torque on the torsion spring. When the external force disappears, the torsion spring will release the generated torque, thereby causing the sealing cover 18 to return to its original position. The protective cover 181 can protect the torsion spring to a certain extent, thereby extending the service life of the torsion spring. By opening and closing the sealing cover 18, the scale inhibitor containing sodium phosphate in the storage tank 19 can flow from the pipe into the water supply pipe 191 through the gravity, thereby combining with the calcium, magnesium and iron ions in the water to form a soluble complex, preventing them from crystallizing and precipitating, and the dosage added each time is very small. Water pipes 191 are arranged at a certain angle on circular fixtures 192. When water is sprayed from nozzles 11, a certain force is generated, which in turn drives the circular fixtures 192 connected to rolling bearings 22 to rotate, thereby generating a larger irrigation area.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
