Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to an anti-clogging multi-angle rotating irrigation nozzle. Background Technology

[0002] In the field of agricultural irrigation, irrigation sprinklers are key equipment for achieving efficient use of water resources. Existing irrigation sprinklers generally achieve primary anti-clogging through built-in filter structures. The filter is usually designed as a flat mesh or a cylindrical mesh, which can filter impurities such as mud, plant debris, and microbial flocs in the water, preventing large particles of debris from directly entering the sprinkler outlet and causing blockage, thereby ensuring the stability of irrigation water flow.

[0003] However, with prolonged use, the filter screen is prone to clogging due to the accumulation of impurities. In this case, irrigation operations need to be interrupted to disassemble and clean the nozzle. In traditional structures, the filter screen and the nozzle body are mostly fixedly connected or nested. The disassembly process requires tools, which is inconvenient. Frequent disassembly will also accelerate the wear of parts and reduce the service life of the equipment, causing many inconveniences to agricultural production and garden maintenance. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an anti-clogging multi-angle rotating irrigation nozzle to solve the problems mentioned in the background. This invention features a novel structure. By setting up a filtration mechanism consisting of dual filters and a linkage cleaning component, the fan blade shaft is driven to rotate using the kinetic energy of the water flow, which in turn drives the scraper to automatically clean impurities from the filter screen surface. Simultaneously, the impurities are collected and concentrated through a conveying structure. This structure improves the problem of easy clogging of the filter screen and the need for frequent manual cleaning, achieving continuous and efficient filtration, reducing maintenance frequency, and ensuring long-term unobstructed water flow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging multi-angle rotating irrigation nozzle, comprising a mounting frame, an inlet pipe mounted on the lower side of the mounting frame, a horizontal connecting pipe fixedly connected to one side of the inlet pipe, a connecting flange fixedly connected to the upper end of the inlet pipe, a filter mechanism disposed inside the inlet pipe, a nozzle disposed on one side of the mounting frame, an adjustment mechanism cooperating with the nozzle disposed on the upper side of the mounting frame, a corrugated pipe fixedly connected to one end of the horizontal connecting pipe, and one end of the corrugated pipe fixedly connected to one end of the nozzle.

[0006] Furthermore, the filtration mechanism includes two fixed plates fixedly connected to the inner wall of the water inlet pipe. A fan blade shaft is rotatably engaged on the two fixed plates. A conical filter screen and an annular filter screen are arranged sequentially from top to bottom on the inner wall of the water inlet pipe. A conveying pipe is installed between the conical filter screen and the annular filter screen. A conveying blade that cooperates with the inner wall of the conveying pipe is fixedly connected to the fan blade shaft. A fan blade is fixedly connected to the upper end of the fan blade shaft. An arc-shaped scraper that cooperates with the upper side of the conical filter screen is fixedly connected to the fan blade shaft. A filter screen scraper that cooperates with the lower side of the annular filter screen is fixedly connected to the fan blade shaft.

[0007] Furthermore, the two ends of the conveying pipe are respectively connected to a conical filter and an annular filter, the fan blades are matched with the inner wall of the water inlet pipe, and the horizontal connecting pipe is disposed between the conical filter and the annular filter.

[0008] Furthermore, the adjustment mechanism includes a bracket mounted on the upper side of the mounting frame, a rotating block rotatably fitted at the upper end of the bracket, a lead screw threaded onto the rotating block, an L-shaped connecting rod rotatably fitted on one side of the bracket, and a handle fixedly connected to one end of the lead screw.

[0009] Furthermore, the nozzle is fixedly connected to one side of the L-shaped connecting rod, and one end of the lead screw is rotatably engaged with the bend of the L-shaped connecting rod.

[0010] Furthermore, the lower end of the water inlet pipe is threaded with a cleaning cap.

[0011] Furthermore, a sealing ring is fitted on the outer side of the cleaning cap, and the sealing ring cooperates with the lower end of the water inlet pipe.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses a filtration mechanism consisting of a double filter screen and a linkage cleaning component. The water flow itself drives the fan blade shaft to rotate, which in turn drives the scraper to automatically clean impurities on the surface of the filter screen. At the same time, the impurities are collected by a conveying structure. This structure improves the problem of easy clogging of the filter screen and the need for frequent manual cleaning, realizes continuous and efficient filtration, reduces the frequency of maintenance, and ensures long-term smooth water flow.

[0014] 2. This utility model, by setting a screw-driven adjustment mechanism and a rotatable connecting rod structure, can flexibly adjust the spray angle of the nozzle, improving the problem that the existing nozzles have a fixed direction and are difficult to adapt to diverse spraying needs, and expanding the applicability of the equipment.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 5This utility model provides a technical solution: an anti-clogging multi-angle rotating irrigation nozzle, including a mounting frame 1, an inlet pipe 2 mounted on the lower side of the mounting frame 1, a horizontal connecting pipe 3 fixedly connected to one side of the inlet pipe 2, a connecting flange 4 fixedly connected to the upper end of the inlet pipe 2, a filter mechanism 5 disposed inside the inlet pipe 2, a nozzle 6 disposed on one side of the mounting frame 1, an adjustment mechanism 7 cooperating with the nozzle 6 disposed on the upper side of the mounting frame 1, a corrugated pipe 8 fixedly connected to one end of the horizontal connecting pipe 3, and one end of the corrugated pipe 8 fixedly connected to one end of the nozzle 6. A cleaning cap 9 is threadedly fitted to the lower end of the inlet pipe 2. A sealing ring 10 is sleeved on the outer side of the cleaning cap 9, and the sealing ring 10 cooperates with the lower end of the inlet pipe 2. An external water source is connected to the inlet pipe 2 via a connecting flange 4. The water flow is treated by the filter mechanism 5 inside the inlet pipe 2 and then enters the horizontal pipe 3. It is then transported to the nozzle 6 via the corrugated pipe 8. The mounting frame 1 provides support for the overall structure. The cleaning cap 9 at the lower end of the inlet pipe 2 can be opened periodically to clean internal impurities. The sealing ring 10 is fitted on the outside of the cleaning cap 9 and fits against the lower end of the inlet pipe 2 to achieve a seal. This realizes the connection, filtration, transportation and spraying path construction of the water source. The mounting frame 1 ensures the stability of the structure. The cleaning cap 9 and the sealing ring 10 work together to facilitate the cleaning of impurities and prevent water leakage. The corrugated pipe 8 adapts to the positional changes of the nozzle 6 during adjustment to ensure smooth water flow.

[0023] In this embodiment, the filtration mechanism 5 includes two fixed plates 51 fixedly connected to the inner wall of the water inlet pipe 2. A fan blade shaft 52 is rotatably fitted on the two fixed plates 51. A conical filter screen 53 and an annular filter screen 54 are arranged sequentially from top to bottom on the inner wall of the water inlet pipe 2. A conveying pipe 55 is installed between the conical filter screen 53 and the annular filter screen 54. A conveying blade 56 that cooperates with the inner wall of the conveying pipe 55 is fixedly connected to the fan blade shaft 52. A fan blade 57 is fixedly connected to the upper end of the fan blade shaft 52. An arc-shaped scraper 58 that cooperates with the upper side of the conical filter screen 53 is fixedly connected to the fan blade shaft 52. A filter scraper 59 that cooperates with the lower side of the annular filter screen 54 is fixedly connected to the fan blade shaft 52. The two ends of the conveying pipe 55 are respectively connected to the conical filter screen 53 and the annular filter screen 54. The fan blade 57 cooperates with the inner wall of the water inlet pipe 2. A horizontal pipe 3 is arranged between the conical filter screen 53 and the annular filter screen 54. After the water flows into the inlet pipe 2, it first contacts the conical filter screen 53 for preliminary filtration. The water flow impacts the fan blades 57, causing the fan shaft 52 to rotate on the fixed plate 51. As the fan shaft 52 rotates, the arc-shaped scraper 58 rotates against the upper side of the conical filter screen 53, cleaning the impurities attached to its surface. The impurities filtered by the conical filter screen 53 fall through the conveying pipe 55. The conveying blades 56 on the fan shaft 52 cooperate with the inner wall of the conveying pipe 55 to transport the impurities downward to the lower side of the annular filter screen 54. At the same time, the filter... The scraper 59 rotates against the lower side of the annular filter screen 54 to clean impurities from its surface. The impurities are eventually deposited at the lower end of the inlet pipe 2. Two-stage filtration is achieved through the conical filter screen 53 and the annular filter screen 54, which improves filtration efficiency. The fan shaft 52 drives the arc-shaped scraper 58, the conveying blades 56, and the filter screen scraper 59 to move synchronously, automatically cleaning impurities from the filter screen surface and preventing filter screen blockage. The impurities are conveyed and concentrated at the lower end of the inlet pipe 2, which is convenient for subsequent discharge through the cleaning cap 9, ensuring continuous and effective filtration.

[0024] In this embodiment, the adjustment mechanism 7 includes a bracket 71 mounted on the upper side of the mounting frame 1. A rotating block 72 is rotatably fitted to the upper end of the bracket 71, and a lead screw 73 is threaded onto the rotating block 72. An L-shaped connecting rod 74 is rotatably fitted to one side of the bracket 71, and a handle 75 is fixedly connected to one end of the lead screw 73. The nozzle 6 is fixedly connected to one side of the L-shaped connecting rod 74, and one end of the lead screw 73 is rotatably fitted at the bend of the L-shaped connecting rod 74. Rotating handle 75 causes lead screw 73 to move axially within rotating block 72 (rotating block 72 rotates in conjunction with the upper end of bracket 71 to accommodate changes in the angle of lead screw 73). One end of lead screw 73 pushes the bend of L-shaped connecting rod 74, causing L-shaped connecting rod 74 to rotate around the rotation point with bracket 71. This, in turn, causes the nozzle 6 fixed on one side of L-shaped connecting rod 74 to change its angle. Through the extension and retraction transmission of lead screw 73, the angle of L-shaped connecting rod 74 can be adjusted, thereby flexibly changing the spraying direction of nozzle 6 to meet the directional spraying needs in different scenarios. The adjustment process is stable and controllable.

[0025] When using the device, external water enters the inlet pipe 2 through the connecting flange 4, first flowing through the filter mechanism 5. The water flow impacts the fan blades 57, causing the fan blade shaft 52 to rotate on the fixed plate 51. The arc-shaped scraper 58 simultaneously cleans the impurities on the upper side of the conical filter screen 53. The impurities fall through the conveying pipe 55 and are pushed to the lower side of the annular filter screen 54 by the conveying blades 56. The filter screen scraper 59 cleans the impurities on the lower side of the annular filter screen 54. Finally, the impurities are deposited at the lower end of the inlet pipe 2 (which can be discharged by opening the cleaning cap 9; the sealing ring 10 ensures the sealing of the cleaning cap 9 when it is closed). The filtered water flows through the horizontal pipe 3 and the corrugated pipe 8 to the nozzle 6. If it is necessary to adjust the spray direction, turn the handle 75 of the adjusting mechanism 7. The screw 73 moves in the rotating block 72, pushing the L-shaped connecting rod 74 to rotate around the bracket 71, thereby driving the nozzle 6 to adjust the angle and achieve directional spraying.
