However, the existing drip irrigation system still has some problems in actual use. Especially in the long irrigation process, the drip irrigation dripper is easy to be invaded by plant roots, causing blockage, which seriously affects the irrigation effect. Although the existing drip irrigation dripper has some anti-clogging function, it still has deficiencies in preventing root system invasion, which affects the growth and yield of crops after long-term use.

However, this design mainly aims at biofilm clogging problem, and the protection ability against root system invasion is weak. In addition, this design relies on the geometric shape of flow channel and the self-cleaning effect of water flow, and cannot completely avoid the invasion of root system, and may still cause clogging phenomenon after long-term use.

[0027] 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.

[0028] like Figures 1 to 6 As shown, this utility model provides a technical solution: a multi-layer anti-clogging drip irrigation dripper with root intrusion prevention function, including dripper body 1, connecting pipe 11 for installation in dripper body 1 and control valve 12 for control in dripper body 1, and an anti-root intrusion mechanism 2 for preventing root intrusion is provided inside dripper body 1.

An isolation net 23 is fixedly sleeved inside the outer tube 21. The top of the inner tube 22 is fixedly connected to the bottom of the inner wall of the outer tube 21. A flow channel 24 is provided inside the inner tube 22. One end of the flow channel 24 is connected to the connecting tube 11. A drip nozzle 25 is fixedly connected to the other end of the flow channel 24. An anti-clogging protrusion 26 is provided on the outer wall of the drip nozzle 25. Multiple protective layers 27 are fixedly connected to the outer wall of the inner tube 22. An anti-root intrusion agent 28 is provided inside the protective layer 27.

[0030] The external part of the dripper body 1 is provided with a dustproof mechanism 3 to prevent external impurities from entering. The dustproof mechanism 3 includes a dustproof cover 31. The bottom of the dustproof cover 31 is movably connected to the top of the dripper body 1. A plurality of dustproof brushes 32 are fixedly connected to the inner wall of the dustproof cover 31. The bottom of the dustproof brushes 32 is in contact with the top of the dripper body 1.

[0031] The dripper body 1 is provided with an adjustment mechanism 4 for adjusting water flow. The adjustment mechanism 4 includes an adjustment valve 41. The bottom of the adjustment valve 41 is fixedly connected to the top of the inner tube 22. An adjustment rod 42 is fixedly connected to the top of the adjustment valve 41. An adjustment handle 43 is fixedly connected to the top of the adjustment rod 42. The outer wall of the adjustment handle 43 is slidably connected to the top of the dripper body 1.

[0032] Furthermore, the isolation net 23 has a multi-layer structure, and the mesh diameter of each layer of the isolation net 23 decreases sequentially. The root invasion prevention agent 28 is a slow-release type, which can maintain its efficacy for a long time.

[0033] Further, the plurality of anti-blocking protrusions 26 are arranged in a circular equidistant array, and the surfaces of the anti-blocking protrusions 26 are provided with anti-skid lines.

[0034] Further, the protective layer 27 is four layers, and from inside to outside, it is an anti-root intrusion agent layer, a slow-release film layer, a waterproof layer, and an anti-ultraviolet layer.

[0035] The root system intrusion prevention mechanism 2 can effectively prevent root system intrusion into the dripper, thereby avoiding the problem of clogging of the flow channel 24 and the water outlet 25 in the dripper due to root system intrusion. In combination with the dust prevention mechanism 3, it can prevent external impurities from entering the dripper, avoiding the risk of impurities clogging the flow channel 24, and also facilitating cleaning and maintenance of the dripper. The adjusting mechanism 4 can adjust the water flow according to actual irrigation needs, improving irrigation effect and water resource utilization efficiency.

[0036] Further, the dustproof brush 32 is made of nylon material, which has good wear resistance and elasticity. The bottom of the dustproof brush 32 is provided with an elastic strip, which can ensure that the dustproof brush 32 is in close contact with the top of the dripper body 1.

[0037] Further, the outer wall of the adjusting rod 42 is provided with scale lines, which can directly show the adjustment range of the water flow.

[0038] Further, the top of the dust cover 31 is fixedly connected with a plurality of air holes 311 arranged in a circular equidistant array.

[0039] Further, the outer wall of the dust cover 31 is fixedly connected with an anti-skid sleeve 312, and the surface of the anti-skid sleeve 312 is provided with anti-skid lines, which is convenient for manual operation.

[0040] Firstly, the outer pipe 21 and the inner pipe 22 are provided, and the isolation net 23 in the outer pipe 21 can effectively block the root system intrusion. The multi-layer structure design of the isolation net 23 makes the mesh gradually smaller, forming an effective filtering effect. The flow channel 24 and the water outlet 25 in the inner pipe 22 are designed reasonably, and the anti-blocking protrusions 26 on the water outlet 25 can prevent the root system or other impurities from clogging the water outlet 25. At the same time, the anti-skid lines on the surface of the anti-blocking protrusions 26 increase the friction, preventing the root system from growing on the surface.

[0041] The protective layer 27 on the outer wall of the inner pipe 22 includes four layers, which are an anti-root intrusion agent layer, a slow-release film layer, a waterproof layer, and an anti-ultraviolet layer. The slow-release agent in the anti-root intrusion agent layer can be continuously released, maintaining the drug effect for a long time, effectively preventing root system intrusion. The slow-release film layer can control the release speed of the agent, ensuring the durability of the drug effect. The waterproof layer and the anti-ultraviolet layer respectively protect the agent layer from the influence of water and ultraviolet rays, prolonging the effective period of the agent.

[0042] The dust cover 31 in the dustproof mechanism 3 can prevent external impurities from entering the internal part of the dripper, and the dust brush 32 on the inner wall of the dust cover 31 is in contact with the top of the dripper body 1, which can effectively prevent impurities from entering. The elastic strip at the bottom of the dust brush 32 ensures that the dust brush 32 is in close contact with the top of the dripper body 1, thereby improving the dustproof effect. At the same time, the air hole 311 at the top of the dust cover 31 can ensure the ventilation of the internal part of the dripper, thereby avoiding excessive internal pressure. The anti-skid sleeve 312 on the outer wall of the dust cover 31 increases the convenience of operation.

[0043] The adjusting valve 41 in the adjusting mechanism 4 realizes the adjustment of the water flow size through the adjusting rod 42 and the adjusting handle 43. The scale line on the adjusting rod 42 can directly show the adjustment range of the water flow, thereby facilitating the user to adjust according to the actual irrigation demand. The sliding connection design between the adjusting handle 43 and the top of the dripper body 1 makes the adjusting operation more convenient.

[0044] The above is only the preferred specific implementation mode of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
