Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, and in particular to an external patch-type variable flow channel anti-clogging drip irrigation tape. Background Technology

[0002] Drip irrigation, as a highly efficient and water-saving irrigation technology, is widely used. Patch-type drip irrigation tape is widely adopted due to its simple installation and low cost. However, poor water quality or improper filter use often causes dripper clogging, severely affecting the lifespan of the drip irrigation tape and irrigation efficiency. The key to the development of drip irrigation tape technology lies in how to restore normal water flow from clogged drippers without replacing the drip irrigation tape, thereby improving irrigation uniformity and extending the lifespan of the drip irrigation tape. Utility Model Content

[0003] This invention provides an external patch-type variable flow channel anti-clogging drip irrigation tape to overcome the deficiencies in the prior art.

[0004] This utility model provides an external patch-type variable flow channel anti-clogging drip irrigation tape, including a drip irrigation tape, on which a drip irrigation assembly is disposed, the drip irrigation assembly including:

[0005] The housing is disposed on the drip irrigation tape and is fixedly connected to the drip irrigation tape;

[0006] A rack is disposed inside the housing and is slidably connected to the housing;

[0007] A pitch-changing assembly is disposed on the housing and fixedly connected to the rack.

[0008] According to the present invention, an external patch-type variable flow channel anti-clogging drip irrigation tape is provided, wherein the shell is a hollow structure with grooves on both sides, and the lower end of the toothed rack is disposed in the groove; a filter screen is disposed inside the shell on one side of the toothed rack, and the drip irrigation tape is provided with an outlet corresponding to the filter screen.

[0009] According to the present invention, an external patch-type variable flow channel anti-clogging drip irrigation tape is provided, wherein two racks are provided, the two racks are arranged in a relative and cooperative manner, and a labyrinth flow channel is formed between the two racks, the filter screen is provided at the water inlet end of the flow channel, and the water outlet end of the flow channel is provided with a drip irrigation port on the shell corresponding to the water outlet end of the casing.

[0010] According to the present invention, an external patch-type variable flow channel anti-clogging drip irrigation tape is provided, wherein the variable pitch component includes:

[0011] A movable rod, one end of which is fixedly connected to the rack, and the other end of which extends through the housing to the outside of the housing;

[0012] A telescopic spring is disposed in a groove in the housing, with one end fixedly connected to the inner wall of the groove and the other end fixedly connected to the rack.

[0013] According to the present invention, an external patch-type variable flow channel anti-clogging drip irrigation tape is provided, wherein multiple moving rods and telescopic springs are provided, respectively disposed on two racks.

[0014] This utility model provides an externally mounted, patch-type variable-channel anti-clogging drip irrigation tape. When the labyrinth channel is blocked by particles, the increased water pressure after blockage compresses the toothed rack, increasing its spacing and thus the cross-sectional area of ​​the labyrinth channel cavity. The pressure of the water flow within the labyrinth channel forces the blockage out of the drip hole, achieving a self-flushing function. The spacing can also be increased by pulling a moving rod. The toothed rack features an arc-shaped groove design. When water pressure acts on the surface of the arc-shaped grooved teeth, a force perpendicular to the grooved teeth is generated, causing the grooved teeth to compress against the sidewalls of the drip irrigation housing. Under this force, the water flow turbulence in the channel is enhanced, making it easier to flush out the blocking particles and improving the anti-clogging performance of the dripper. This allows for the restoration of normal water flow from blocked drippers without replacing the drip irrigation tape, improving irrigation uniformity and extending the service life of the drip irrigation tape.

[0022] See appendix Figure 1-2 This application provides an external patch-type variable flow channel anti-clogging drip irrigation tape, including a drip irrigation tape 1, on which a drip irrigation component 2 is disposed, the drip irrigation component 2 including:

[0023] The housing 21 is disposed on the drip irrigation tape 1 and is fixedly connected to the drip irrigation tape 1;

[0024] A rack 22 is disposed inside the housing 21 and is slidably connected to the housing 21;

[0025] The pitch-changing assembly 23 is disposed on the housing 21 and is fixedly connected to the rack 22.

[0026] To further optimize the above technical solution, the shell 21 has an internal hollow structure with grooves on both sides, and the lower end of the rack 22 is located in the groove; a filter screen 211 is provided inside the shell 21 on one side of the rack 22, and an outlet 11 is provided on the drip irrigation tape corresponding to the filter screen 211.

[0027] To further optimize the above technical solution, two racks 22 are provided, which are arranged in a relative and cooperative manner to form a labyrinth flow channel between the two racks 22. The filter screen 211 is provided at the water inlet end of the flow channel, and the water outlet end of the flow channel is provided with a drip irrigation port 212 on the housing 21.

[0028] To further optimize the above technical solution, the pitch component 23 includes:

[0029] The movable rod 231 has one end fixedly connected to the rack 22, and the other end extends through the housing 21 to the outside of the housing 21.

[0030] The telescopic spring 232 is disposed in the groove of the housing 21, with one end fixedly connected to the inner wall of the groove of the housing 21 and the other end fixedly connected to the rack 22.

[0031] To further optimize the above technical solution, multiple moving rods 231 and telescopic springs 232 are provided, respectively disposed on two racks 22.

[0032] Working principle: Water flows through the filter screen 211 and enters the labyrinth channel, then flows out from the drip nozzle 212. When a blockage occurs in the channel, the water pressure increases due to the blockage, which squeezes the racks 22 on both sides. The racks 22 are squeezed and then compress the telescopic spring 232, thereby increasing the distance between the two racks 22. This allows the blockage to be flushed out of the housing by the water flow, achieving self-cleaning. The racks 22 return to their initial position under the elastic force of the telescopic spring 232. If necessary, the distance between the racks 22 can be increased by manually pulling the moving rod 231.

[0033] This utility model provides an externally mounted, patch-type variable-channel anti-clogging drip irrigation tape. When the labyrinth channel is blocked by particles, the increased water pressure after blockage compresses the toothed rack, increasing its spacing and thus the cross-sectional area of ​​the labyrinth channel cavity. The pressure of the water flow within the labyrinth channel forces the blockage out of the drip hole, achieving a self-flushing function. The spacing can also be increased by pulling a moving rod. The toothed rack features an arc-shaped groove design. When water pressure acts on the surface of the arc-shaped grooved teeth, a force perpendicular to the grooved teeth is generated, causing the grooved teeth to compress against the sidewalls of the drip irrigation housing. Under this force, the water flow turbulence in the channel is enhanced, making it easier to flush out the blocking particles and improving the anti-clogging performance of the dripper. This allows for the restoration of normal water flow from blocked drippers without replacing the drip irrigation tape, improving irrigation uniformity and extending the service life of the drip irrigation tape.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
