Description

Technical Field

[0001] The utility model relates to the technical field of irrigation, and particularly relates to an anti-blocking internally inlaid patch drip irrigation tape structure. Background Art

[0002] Drip irrigation is an efficient irrigation technology. It directly conveys water to the soil near the roots of crops for irrigation at a very low flow rate. Drip irrigation usually uses drip irrigation tapes. The drip irrigation tapes directly convey water to the fields through a low-pressure pipeline system, and then through the drip heads installed on the pipelines or the drip irrigation tapes themselves, the water is evenly and slowly dripped onto the soil near the roots of crops at a very small flow rate. The patch drip irrigation tape is a type of drip irrigation tape, which has continuous patches, and each patch has a water dripping hole, so as to achieve a continuous water dripping effect. However, in the prior art, since drip irrigation cannot ensure that the irrigation water is completely filtered at the front end of the drip irrigation tape, there are still a small amount of impurities flowing in the pipe with the water flow, which easily causes blockage at the water inlet of some patches of the patch drip irrigation tape, thereby affecting the unstable water supply for crops. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an anti-blocking internally inlaid patch drip irrigation tape structure.

[0004] In order to solve the above technical problem, the technical solution of the utility model is as follows:

[0005] An anti-blocking internally inlaid patch drip irrigation tape structure includes a first tape section, a second tape section, an anti-blocking joint, and patch drip heads; the anti-blocking joint is located between the first tape section and the second tape section and is detachably connected to the first tape section and the second tape section; a plurality of patch drip heads are evenly arranged on the first tape section and the second tape section; the anti-blocking joint includes a first pipe section and second pipe sections symmetrically arranged on both sides of the first pipe section; the first pipe section and the second pipe sections are integrally formed; a filter screen is vertically fixedly connected inside the first pipe section.

[0006] Further, the diameter of the first pipe section is larger than that of the second pipe section.

[0007] Further, two connecting pipes are symmetrically communicated with the first pipe section wall relative to the filter screen; the two connecting pipes are separated by the filter screen; a sealing cover is detachably connected to the connecting pipes.

[0008] Further, a first protrusion and a second protrusion are integrally formed on the second pipe section; a locking nut is threadedly connected between the first protrusion and the second protrusion; a sealing ring is attached to the locking nut.

[0009] Further, the patch drip head includes a drip head body, a water inlet chamber, a strip-shaped water inlet hole, a water outlet chamber, a turbulent flow channel, and a strip-shaped filter element; a water inlet chamber, a water outlet chamber, and a turbulent flow channel are formed on the front surface of the drip head body; the water inlet chamber and the water outlet chamber are connected through two symmetrically arranged turbulent flow channels; the turbulent flow channel is curved; a strip-shaped water inlet hole communicating with the back surface of the drip head body is formed at the bottom of the water inlet chamber; a strip-shaped filter element is fixedly connected to the opening on one side of the back surface of the drip head body where the strip-shaped water inlet hole is located; a plurality of water leakage round holes are formed on the two side walls of the strip-shaped filter element; water outlet holes are correspondingly formed on the drip irrigation belt walls where the first belt section and the second belt section are located at the water outlet chamber.

[0010] Further, two strip-shaped water inlet holes are provided; the number of strip-shaped filter elements corresponds to the number of strip-shaped water inlet holes provided.

[0011] Further, the strip-shaped filter element is a trapezoidal column body with a hollow interior.

[0012] Advantages of the present utility model:

[0013] By providing a filter screen in the first pipe section of the anti-blocking joint, the unfiltered impurities remaining in the first belt section and the second belt section can be further removed, effectively ensuring that they do not flow inside the drip irrigation belt, preventing the drip irrigation belt from being blocked, and improving the drip irrigation effect. By fixedly connecting a strip-shaped filter element to the opening on one side of the back surface of the drip head body where the strip-shaped water inlet hole is located, the strip-shaped filter element further ensures the removal of residual impurities, and the water leakage round holes are formed on the two side walls of the strip-shaped filter element. Since the two side walls of the strip-shaped filter element are in the same direction as the water flow direction, it effectively prevents the impurities from staying in the water leakage round holes all the time, ensuring the uniformity of the water flow of the patch drip head.

[0024] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the following described various embodiments of the present invention can be combined with each other as long as they do not conflict with each other.

[0025] Refer to Figures 1-6 As shown, an anti-clogging inlaid patch type drip irrigation tape structure includes a first tape section 1, a second tape section 2, an anti-clogging joint 3, and a patch dripper 4; the anti-clogging joint 3 is located between the first tape section 1 and the second tape section 2 and is detachably connected to the first tape section 1 and the second tape section 2; a plurality of patch drippers 4 are evenly arranged on the first tape section 1 and the second tape section 2; the anti-clogging joint 3 includes a first pipe section 31 and second pipe sections 32 symmetrically arranged on both sides of the first pipe section 31; the first pipe section 31 and the second pipe sections 32 are integrally formed; a filter screen 33 is vertically fixed inside the first pipe section 31.

[0026] It should be noted that both the first tape section 1 and the second tape section 2 are the main parts of the drip irrigation tape, which can be connected through the anti-clogging joint 3, and the position of the anti-clogging joint 3 can be set according to actual situations; the patch dripper 4 can effectively drip the water in the drip irrigation tape for irrigation; by arranging the filter screen 33 in the first pipe section 31, the unfiltered impurities remaining in the first tape section 1 and the second tape section 2 can be further removed, effectively ensuring that they do not flow inside the drip irrigation tape, preventing the drip irrigation tape from being blocked, and improving the drip irrigation effect.

[0027] Specifically, in order to retain the impurities, the diameter of the first pipe section 31 is larger than that of the second pipe section 32, so that the impurities stay in the first pipe section 31 for subsequent removal.

[0028] Specifically, two connecting pipes 34 are symmetrically communicated with the wall of the first pipe section 31 relative to the filter screen 33; the two connecting pipes 34 are separated by the filter screen 33; a sealing cover 35 is detachably connected to the connecting pipe 34.

[0029] Specifically, to facilitate the stable sealed connection between the anti-blocking joint 3 and the first tape segment 1 and the second tape segment 2 of the drip irrigation tape, a first protrusion 36 and a second protrusion 37 are integrally formed on the second pipe segment 32; a lock nut 38 is threadedly connected between the first protrusion 36 and the second protrusion 37; a sealing ring 39 is attached to the lock nut 38.

[0030] Specifically, the patch drip head 4 includes a drip head main body 41, a water inlet cavity 42, a water inlet strip hole 43, a water outlet cavity 44, a turbulent flow channel 45, and a strip-shaped filter element 46; a water inlet cavity 42, a water outlet cavity 44, and a turbulent flow channel 45 are formed on the front surface of the drip head main body 41; the water inlet cavity 42 and the water outlet cavity 44 are connected through two symmetrically arranged turbulent flow channels 45; in order to ensure uniform water flow, the turbulent flow channel 45 is curved; a water inlet strip hole 43 communicating with the back surface of the drip head main body 41 is formed at the bottom of the water inlet cavity 42; a strip-shaped filter element 46 is fixedly connected to the opening on one side of the back surface of the drip head main body 41 where the water inlet strip hole 43 is located; a number of water leakage round holes 461 are formed on both side walls of the strip-shaped filter element 46; water outlet holes are correspondingly formed on the drip irrigation tape wall at the water outlet cavity 44 of the first tape segment 1 and the second tape segment 2. The drip head main body 41 can be easily attached to the inner walls of the first tape segment 1 and the second tape segment 2 of the drip irrigation tape; the two symmetrically arranged turbulent flow channels 45 between the water inlet cavity 42 and the water outlet cavity 44 can generate sufficient pressure drop, so that the flow rates passing through the turbulent flow channels 45 are basically the same, realizing stable and uniform irrigation of crops. The strip-shaped filter element 46 further ensures the removal of residual impurities, and the water leakage round holes 461 are formed on both side walls of the strip-shaped filter element 46. Since the two side walls of the strip-shaped filter element 46 are in the same direction as the water flow direction, it effectively prevents the strip-shaped filter element 46 from staying in the water leakage round holes 461 all the time, ensuring the uniformity of the water flow of the patch drip head 4.

[0031] Specifically, in this application, two water inlet strip holes 43 are provided; the number of strip-shaped filter elements 46 corresponds to the number of water inlet strip holes 43 provided.

[0032] Specifically, in order to further ensure the blockage of the water leakage round holes 461, the strip-shaped filter element 46 is a trapezoidal column with a hollow interior.

[0033] The working principle of the present utility model:

[0034] When drip irrigation is carried out, anti-clogging joints 3 are detachably connected between multiple first belt segments 1 and second belt segments 2. By arranging a filter screen 33 in the first pipe segment 31 of the anti-clogging joint 3, it is possible to further remove the unfiltered impurities remaining in the first belt segment 1 and the second belt segment 2, effectively ensuring that they do not flow inside the drip irrigation belt, preventing the drip irrigation belt from being blocked, and improving the drip irrigation effect. To further ensure that the patch drip head 4 is not blocked, a strip-shaped filter element 46 is fixedly connected to the opening on the back side of the drip head body 41 where the water inlet strip hole 43 is located. The strip-shaped filter element 46 further ensures the removal of residual impurities, and the water leakage round holes 461 are formed on both side walls of the strip-shaped filter element 46. Since the water flow direction of both side walls of the strip-shaped filter element 46 is the same, it effectively prevents the impurities from staying in the water leakage round holes 461 all the time, ensuring the uniformity of the water flow of the patch drip head 4.

[0035] The above embodiments of the present invention have been described in detail in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
