DETAILED DESCRIPTION

[0020] Embodiment 1, as Figure 1-Figure 6 As shown, the present application provides an anti-clogging dripper, including a dripper body 100, on which a water inlet hole 110 is provided, and the water inlet hole 110 passes through the dripper body 100; A turbulent groove 120 and a water outlet groove 130 are arranged on the first surface of the dripper body 100. The turbulent groove 120 is distributed around the outer side of the water inlet hole 110. One end of the turbulent groove 120 is connected to the water inlet hole 110, and the leading end of the turbulent groove 120 is connected to the water outlet groove 130. A plurality of alternately arranged water retaining ribs 121 are arranged on both sides of the turbulent groove 120 along the flow direction of the water flow. A recessed portion 122 is arranged on the upstream surface of the water retaining rib 121. The recessed portion 122 is configured to guide the water flowing through to form a vortex. The second surface of the dripper body 100 is provided with a water inlet groove 140; two first ribs 150 arranged side by side are provided in the water inlet groove 140, and the water inlet hole 110 is located between the two first ribs 150; a plurality of guide plates 160 arranged side by side are provided in the water inlet hole 110, and the guide plates 160 are arranged obliquely relative to the first ribs 150, and the guide plates 160 extend out of the water inlet hole 110 and extend to the two sides of the end of the water inlet groove 140. The water guide ribs 170 are connected to the first ribs 150 on the corresponding side; The two adjacent guide plates 160 form a first water inlet area in the water inlet groove 140 , and the side portions of the two adjacent water guide ribs 170 on the same first rib 150 form a second water inlet area; The dripper body 100 is an overall long strip structure, the water inlet hole 110 is arranged at one end of the dripper body 100, and the water outlet groove 130 is arranged at the other end of the dripper body 110.

[0021] Specifically, a turbulence groove 120 and a water outlet groove 130 are formed on the first surface of the dripper body 100, and a water inlet groove 140 is formed on the second surface of the dripper body 100. The first surface and the second surface of the dripper body 100 are arranged back to back, and the water inlet hole 110 runs through the dripper body 100.

[0022] After the dripper body 100 is processed on the inner tube wall of the tube body of the drip irrigation pipe, the first surface of the dripper body 100 is combined with the inner tube wall of the tube body of the drip irrigation pipe, so that a water inlet cavity is formed between the water inlet hole 110 and the inner wall of the tube body, a turbulent channel is formed between the turbulent groove 120 and the inner wall of the tube body, and a water outlet cavity is formed between the water outlet groove 130 and the inner wall of the tube body.

[0023] During use, the water in the tube body is subjected to water pressure during the flow process, and the water will flow from the water inlet groove 140 into the water inlet hole 110. The water in the water inlet hole 110 is turbulently processed by the water retaining ribs 121 in the turbulent groove 120 and finally flows into the water outlet groove 130.

[0024] When the water flows in the turbulent groove 120, along the flow direction of the water in the turbulent groove 120, the water will be blocked by the water retaining ribs 121 arranged alternately and staggered on both sides of the turbulent groove 120 to achieve turbulent flow. When the water is blocked by the water retaining ribs 121, impurities (silt) mixed in the water will be blocked by the multiple water retaining ribs 121 at the water inlet end of the turbulent groove 120. After long-term use, the water retaining ribs 121 arranged at the water inlet end of the turbulent groove 120 will be blocked due to excessive accumulation of silt, resulting in blockage of the turbulent groove 120.

[0025] To this end, a recessed portion 122 is provided on the upstream surface of the water retaining rib 121. The shape of the recessed portion 122 is designed to guide the water flow to form a vortex in the area where the recessed portion 122 is located. For example, the inner concave surface of the recessed portion 122 can be an arc surface. In this way, after the water flow passes through the recessed portion 122, it will be guided by the arc surface to swirl and form a vortex.

[0026] Under the action of the vortex, the silt left behind by the flow obstruction on the front face of the water retaining rib 121 can be carried away by the vortex water flow, thereby reducing the silt accumulation on the front face of the water retaining rib 121 and causing blockage of the turbulent groove 120, thereby improving the anti-blockage performance.

[0027] As for the water flow at the water inlet groove 140, when it flows into the water inlet hole 110, the water flow can enter the water inlet hole 110 from the first water inlet area. At the same time, the water flow can also flow into the water inlet hole 110 from the second water inlet area formed on the side of the water guide rib 170, thereby realizing water inflow from three directions.

[0028] In this way, during the water inlet process, when blockage occurs in any direction, water can also be introduced through other directions to improve the anti-blockage performance.

[0029] By providing a recessed portion 122 on the water retaining rib 121 of the turbulent groove 120, the recessed portion 122 is formed on the upstream surface of each water retaining rib 121. When the water flows in the turbulent groove 120, after the water flows into the recessed portion 122, the inner concave structure of the recessed portion 122 will cause the water to swirl at this position to form a vortex. Under the action of the vortex, it is possible to prevent sediment from gathering on the upstream surface of the water retaining rib 121 that blocks the flow of water. The sediment will be carried away by the vortex formed by the recessed portion 122 and finally enter the water outlet groove 130 for output. In this way, the turbulent groove 120 can be reduced from being blocked due to excessive sediment accumulation. At the same time, In the process of the water in the drip irrigation pipe passing through the water inlet groove 140 and flowing into the water inlet hole 110, on the one hand, the first ribs 150 on both sides of the water inlet hole 110 can protect the edges of the water inlet hole 110 to reduce the large particles of sediment from directly entering the water inlet hole 110 from one side, and on the other hand, the first water inlet area formed by the guide plate 160 and the second water inlet area formed by the side of the water guide rib 170 can realize water inlet from three directions of the water inlet hole 110 to effectively prevent blockage, so as to ensure that the water inlet hole 110 can normally inlet water, thereby improving the anti-blocking performance of the anti-blocking dripper and improving the reliability of the use of the drip irrigation pipe.

[0030] In one embodiment, the recessed portion 122 is further configured to guide the flowing water to flow toward the water retaining ribs 121 arranged adjacent to each other and offset upstream of the water flow.

[0031] Specifically, the recessed portion 122 provided on the water retaining rib 121 in the turbulent groove 120 can form a vortex, and under the action of the vortex, the water will flow toward the water retaining rib 121 on the other side of the turbulent groove 120 which is arranged adjacent to the upstream side.

[0032] In this way, the water flowing in the turbulence groove 120 will also have a tendency to flow in the opposite direction, reducing the flow velocity of the water in the turbulence groove 120 and enhancing the turbulence capacity of the turbulence groove 120, so as to achieve a better drip irrigation effect.

[0033] Furthermore, the water retaining rib 121 as a whole extends obliquely away from the flow direction of the water flow in the turbulent groove 120; The end of the flow-facing surface of the water retaining rib 121 is further provided with a guide surface 123, and the guide surface 123 extends obliquely along the water flow direction in the turbulent groove 120; The guide surface 123 is configured to guide the water flowing through it to flow toward the water retaining ribs 121 arranged adjacent to each other and offset downstream of the water flow.

[0034] Specifically, the water retaining rib 121 extends obliquely as a whole in the direction opposite to the flow trend of the water flow, so as to enhance the blocking effect on the water flow.

[0035] The guide surface 123 provided at the end of the flow-facing surface of the water retaining rib 121 can also guide the water flow to flow toward the water retaining rib 121 located downstream and offset from the other side of the turbulent groove 120. Under the guidance of the guide surface 123, the water flow will be directed toward the concave portion 122 of the next water retaining rib 121, so that the concave portion 122 of the downstream water retaining rib 121 generates a better vortex.

[0036] Furthermore, the recessed portion 122 is arranged at the root of the water retaining rib 121; The back flow surface of the water retaining rib 121 forms a water retaining surface 124; the water retaining surface 124 extends obliquely away from the flow direction of the water flow in the turbulent groove 120; The water retaining surface 124 is configured to guide water to flow toward the water retaining ribs 121 that are arranged adjacent to each other and staggered upstream of the water flow.

[0037] Specifically, a water retaining surface 124 is formed on the back flow surface of the water retaining rib 121. The water retaining surface 124 guides the vortex formed by the downstream water retaining rib 121. After hitting the water retaining surface 124, the vortex is restricted, and part of the water flow forming the vortex will flow back to the water retaining rib 121 where the vortex is generated, so as to improve the effect of the vortex in dispersing impurities and improve the anti-blocking ability.

[0038] In one embodiment of the present application, a second rib 180 is further provided in the water inlet groove 140. The second rib 180 is arranged on the side of the first rib 150. The second rib 180 extends along the extension direction of the first rib 150. The second rib 180 is provided with spaced-apart protrusions 190, and a water flow interval is formed between two adjacent protrusions 190.

[0039] Specifically, a second rib 180 is provided on one side of the first rib 150, and a protrusion 190 protruding outward is provided on the second rib 180. The protrusion 190 can further block mud and other debris, so that the water flowing through the water flow interval and entering the water inlet 110 can be filtered by the protrusion 190.

[0040] Furthermore, the water guide rib 170 extends in a direction perpendicular to the first rib 150 , and the protrusion 190 is arranged opposite to the second water inlet area at a corresponding position.

[0041] Specifically, for the water guiding rib 170, the water guiding rib 170 extends from the edge of the guide plate 160 toward the outside of the water inlet hole 110, and the extension direction of the water guiding rib 170 is perpendicular to the first rib 150 and directly opposite to the water flow gap formed between two adjacent protrusions 190 at corresponding positions, so that the water flowing to the water inlet hole 110 through the water flow gap will hit the water guiding rib 170, and the mud and sand mixed in the water flow can be blocked by the water guiding rib 170, further playing the role of filtering the mud and sand.

[0042] Preferably, the height of the second rib 180 is greater than the height of the first rib 150; A first buffer groove 101 is formed between the second rib 180 and the adjacent first rib 150 , and a second buffer groove 102 is formed between the second rib 180 and the inner groove wall of the water inlet groove 140 .

[0043] Specifically, for the first rib 150 and the second rib 180 arranged adjacent to each other in the water inlet groove 140, the height of the outer second rib 180 is higher than that of the first rib 150, so that the depth of the first buffer groove 101 is greater than the depth of the second buffer groove 102. In actual use, after the water flow is blocked and filtered by the protrusion 190 of the second rib 180, the silt can be deposited in the first buffer groove 101, and the silt in the first buffer groove 101 can flow out along with the water flow.

[0044] The height of the second rib 180 is greater than that of the first rib 150, which can minimize the amount of sediment in the water flowing toward the first rib 150. The water flowing over the second rib 180 toward the first rib 150 will be blocked by the water guide rib 170 to further filter the sediment, and the filtered sediment is deposited in the second buffer groove 102, and the sediment in the second buffer groove 102 can flow out along with the water flow.

[0045] The bottom surface of the second buffer groove 102 extends obliquely from the outside to the inside toward the water inlet hole 110 .

[0046] Specifically, the surface where the dripper body 100 fits with the tube body is usually an arc surface. To this end, the overall depth of the second buffer groove 102 is increased, and the bottom surface of the second buffer groove 102 is arranged at an angle so that the bottom surface of the second buffer groove 102 can be designed to conform to the surface of the dripper body 100 to maximize the depth of the second buffer groove 102. In particular, the depth of the second buffer groove 102 adjacent to the second rib 180 is the largest, so as to more effectively meet the requirements of sediment deposition and thereby improve the filtering effect.

[0047] In order to further improve the water inlet smoothness of the water inlet hole 110 , the end of the guide plate 160 away from the water inlet groove 140 has a smooth structure.

[0048] Specifically, a plurality of guide plates 160 are arranged side by side along the length direction of the water inlet hole 110, and the water flowing into the water inlet hole 110 will flow toward the turbulence groove 120. In this way, since the guide plates 160 are rounded at the ends adjacent to the tube body, the water resistance can be effectively reduced, so that the water entering the water inlet hole 110 can flow smoothly to the turbulence groove 120, thereby improving the smoothness of the water outflow.

[0049] Embodiment 2, based on the above embodiment 1, another embodiment of the present application further provides a kind of drip irrigation pipe, comprising a pipe body and an anti-blocking dripper of the above embodiment, wherein the anti-blocking dripper is arranged on the inner wall of the pipe body, a water inlet cavity is formed between the water inlet hole of the anti-blocking dripper and the inner wall of the pipe body, a turbulent flow channel is formed between the turbulent flow groove of the anti-blocking dripper and the inner wall of the pipe body, and a water outlet cavity is formed between the water outlet groove of the anti-blocking dripper and the inner wall of the pipe body; The tube body is provided with a plurality of water outlet holes, and the water outlet holes are communicated with the corresponding cavities.

[0050] Embodiment 3, based on the above embodiment 2, as Figure 7-Figure 12 As shown, another embodiment of the present application further provides a water-saving irrigation system, including a main water supply pipe 3 and a plurality of drip irrigation pipes 5, wherein the plurality of drip irrigation pipes 5 are respectively connected to the main water supply pipe, and the drip irrigation pipes 5 are the drip irrigation pipes in the above-mentioned embodiment 2.

[0051] Furthermore, the main water supply pipe 3 is provided with a plurality of openings 31 , and each opening 31 is provided with a pipe connector.

[0052] The pipe connector includes: a first connector 1 and a second connector 2, wherein the first connector 1 is provided with a first through hole 11, a connecting plate 12 is provided at one end of the first connector 1, an inserting portion 13 extending outward is provided at the edge of the connecting plate 12, an external thread section is also provided at the outer circumference of the first connector 1, and the first through hole 11 also penetrates the connecting plate 12; the second connector 2 is provided with a second through hole 21, and a first internal thread hole 211 is formed at one end of the second through hole 21; the second connector 2 is connected to the first connector 1 through the first internal thread hole 211 and the external thread section, and a clamping sealing space is formed between the second connector 2 and the connecting plate 12. The clamping sealing space is configured to clamp the pipe wall of the main water supply pipe.

[0053] Specifically, the pipe connector in the present application is assembled from a first connector 1 and a second connector 2, wherein the first connector 1 and the second connector 2 cooperate with each other to be assembled into the opening 31 provided on the main water supply pipe 3, so that the water in the main water supply pipe 3 can flow out through the first through hole 11 and the second through hole 21, and the second connector 2 is connected to a drip irrigation pipe, so that the water flowing out of the second through hole 21 will enter the drip irrigation pipe and flow to the corresponding irrigation area.

[0054] For the pipe connector, a connecting plate 12 is provided at one end of the first connecting member 1, and an inserting portion 13 extending outward is also provided at the edge of the connecting plate 12. The size of the inserting portion 13 will be smaller than the size of the opening 31 of the main water supply pipe 3, so that the inserting portion 13 can be easily inserted into the opening 31 during on-site installation to be guided by the inserting portion 13. After the inserting portion 13 is inserted into the opening 31, the first connecting member 1 is further rotated so that the connecting plate 12 is rotated into the opening 31 and finally the connecting plate 12 is located in the main water supply pipe 3 and abuts against the inner pipe wall of the main water supply pipe 3. The second connecting member 2 is matched with the external thread on the first connecting member 1 through the first internal threaded hole 211 on the outside of the main water supply pipe 3 to achieve threaded fixing of the second connecting member 2 on the first connecting member 1. After the second connecting piece 2 is tightened onto the first connecting piece 1, the end surface of the second connecting piece 2 opposite to the connecting plate 12 will be pressed against the pipe wall of the main water supply pipe 3, so that the pipe wall of the main water supply pipe 3 located near the outer periphery of the opening 31 is squeezed between the connecting plate 12 and the end of the second connecting piece 2, thereby achieving sealing of the opening 31 of the main water supply pipe 3.

[0055] In daily use, since the pipe connector can be assembled on site to the main water supply pipe 3, holes can be directly punched on site to form openings 31 according to the irrigation requirements of different areas. Then, the first connecting piece 1 is guided through the insertion portion 13 so that the connecting plate 12 is installed in the main water supply pipe 3, and then sealed and fixed by the second connecting piece 2, the drip irrigation pipe can be connected through the pipe connector.

[0056] In the opening 31 of the insertion portion 13 of the first connecting piece 1 of the pipe connector, the connecting plate 12 of the first connecting piece 1 is abutted against the inner pipe wall of the main water supply pipe 3, and the pipe wall around the opening 31 of the main water supply pipe 3 is clamped in the clamping sealing space of the pipe connector; the drip irrigation pipe is connected to the corresponding second connecting piece 2 of the pipe connector.

[0057] Furthermore, in order to facilitate the installation of the drip irrigation pipe, the irrigation system also includes a multi-way pipe 4, which includes a mounting joint 41 and at least one external joint 42, the external joint 42 is connected to the mounting joint 41, and the mounting joint 41 is arranged in the second through hole 21 of the second connecting member 2, and the drip irrigation pipe is connected to the corresponding external joint 42.

[0058] Specifically, in order to reduce the number of openings 31 and meet the installation requirements of multiple drip irrigation pipes, the drip irrigation pipes to be installed on the pipe connector are transitionally connected through the multi-way pipe 4. During the connection process, the multi-way pipe 4 is threadedly connected to the second internal threaded hole 212 through the installation joint 41, and the drip irrigation pipe can be installed on the corresponding external joint 42.

[0059] In order to improve the connection reliability, a conventional pipeline quick connection method can be used for the sealing connection between the external joint 42 and the drip irrigation pipe. For example, the external joint 42 is also provided with a locking sleeve 43, the drip irrigation pipe is inserted into the external joint 42, and the drip irrigation pipe is sealed and clamped between the external joint 42 and the locking sleeve 43.

[0060] Specifically, when assembling the drip irrigation pipe, the pipe mouth of the drip irrigation pipe is sleeved on the outside of the external joint 42 and inserted into the locking sleeve 43. Then, the locking sleeve 43 and the threaded engagement on the surface of the external joint 42 are moved outward so that the end of the drip irrigation pipe is pressed between the locking sleeve 43 and the external joint 42.

[0061] Furthermore, in order to facilitate the operator to accurately and smoothly insert the insertion portion 13 into the opening 31 of the main water supply pipe 3, the insertion portion 13 has a pointed structure, and an inclined surface 14 is formed on one side of the insertion portion 13.

[0062] Specifically, the insertion portion 13 has a pointed structure along its outward extension direction, so that during operation, the insertion portion 13 can be accurately inserted into the opening 31 through the pointed tip of its head.

[0063] During the rotation of the first connecting member 1, the side of the insertion portion 13 squeezed by the edge of the opening 31 forms an inclined surface 14. Guided by the inclined surface 14, the first connecting member 1 can rotate more smoothly during the rotation process, so as to smoothly rotate the connecting plate 12 into the opening 31, thereby improving the convenience of operation.

[0064] In addition, the inclined surface 14 is configured to guide the insertion portion 13 to be spirally inserted into the water supply pipe in a direction inclined relative to the center line of the opening 31 of the main water supply pipe 3. Specifically, when the first connecting member 1 is connected to the opening 31 of the main water supply pipe 3, the first connecting member 1 first allows the insertion portion 13 to be inserted into the opening 31 in an inclined manner. The added inclined surface 14 can well guide the pipe wall around the opening 31 of the main water supply pipe 3 to slide to the upper surface of the connecting plate 12 during the tilting rotation process, so as to reduce the damage caused by excessive force on the edge of the opening 31 during the rotation process. By utilizing the rotational guiding method of the automobile tire sleeve on the wheel hub, the large-sized connecting plate 12 can be inserted into the small-sized opening 31, ultimately meeting the requirements of on-site drilling and installation.

[0065] Furthermore, in order to facilitate the operator to apply the rotational driving force to the first connecting member 1, the cross-sectional shape of the first through hole is non-circular.

[0066] Specifically, the cross section of the first through hole is non-circular, so that a tool can be inserted into the first through hole to apply external force during the rotation of the first connecting member 1. For example, the cross section of the first through hole can be plum blossom-shaped, triangular or rectangular.

[0067] Furthermore, in order to improve the sealing of the opening 31, at least one annular rib 22 is provided on the end surface of the second connecting member 2 opposite to the connecting plate 12, and the annular rib 22 surrounds the outer circumference of the first through hole.

[0068] Specifically, the end surface of the second connector 2 opposite to the connecting plate 12 is provided with a protruding annular rib 22. After the second connector 2 is connected to the first connector 1 and the pipe wall of the main water supply pipe 3 is clamped therebetween, the annular rib 22 will be further pressed against the outer pipe wall of the main water supply pipe 3. At the same time, the annular rib 22 is also distributed around the periphery of the opening 31. In this way, the pipe wall outside the opening 31 is further compacted against the connecting plate 12 by the annular rib 22, and the annular rib 22 effectively improves the sealing performance of the opening 31.

[0069] Wherein, multiple annular ribs 22 may be provided on the end surface of the second connecting member 2 as required, and the multiple annular ribs 22 are arranged concentrically; Two adjacent annular ribs 22 are configured to form a sealing area on the pipe wall of the water supply pipe.

[0070] Specifically, the plurality of annular ribs 22 press the pipe wall of the main water supply pipe 3 tightly against the connecting plate 12 , and a sealing area with good sealing performance is formed between two adjacent annular ribs 22 . The sealing area surrounds the opening 31 to improve the sealing performance of the periphery of the opening 31 .

[0071] Furthermore, a paddle 23 is further provided on the outer wall of the second connecting member 2 .

[0072] Specifically, during the process of tightening the second connecting member 2 , the operator can apply a rotational driving force to the second connecting member 2 through the paddle 23 , so that the operator can install the second connecting member 2 without tools.

[0073] Furthermore, in order to meet the requirements of an external drip irrigation pipe, a second internal threaded hole 212 is provided at the other end of the second through hole 21. The second internal threaded hole 212 is coaxially arranged with the first internal threaded hole 211, and the aperture of the second internal threaded hole 212 is larger than the aperture of the first internal threaded hole 211.

[0074] Specifically, the second internal threaded hole 212 is used to meet the connection requirements of the external drip irrigation pipe. The diameter of the first internal threaded hole 211 is designed to be smaller than that of the second internal threaded hole 212, so that when the second connecting member 2 is tightened to the first connecting member 1, it can be ensured that the second connecting member 2 can be tightened and assembled in place, so as to ensure the reliability of the sealed connection between the pipe connector and the main water supply pipe 3.

[0075] Based on the above irrigation system, the present application also provides an assembly method of the irrigation system, including: The main water supply pipe 3 is perforated to form a plurality of openings 31 .

[0076] Specifically, the position of the opening 31 on the main water supply pipe 3 can be set according to the distribution position of the on-site irrigation area, so that the opening 31 can be as close to the irrigation area as possible to shorten the overall use length of the drip irrigation pipe.

[0077] The first connector 1 is inserted into the opening 31 with the insertion portion 13 tilted relative to the opening 31, and then the first connector 1 is rotated so that the connecting plate 12 rotates into the opening 31 and abuts against the inner tube wall of the main water supply pipe 3. Specifically, after the opening 31 is made, the first connector 1 is installed into the corresponding opening 31 on site. Therefore, how to conveniently install the first connector 1 is the key to determining whether the technology can be promoted. In the process of installing the first connector 1 into the opening 31, the insertion portion 13 is used for guidance, and the first connector 1 is gradually rotated so that the connecting plate 12 is screwed into the opening 31, and finally the connecting plate 12 abuts against the inner tube wall of the main water supply pipe 3. Preferably, by providing an inclined surface 14 on the insertion portion 13, during assembly, the first connecting member 1 is first arranged at an angle and the insertion portion 13 is inserted into the opening 31. Then, in the process of rotating the first connecting member 1, as the connecting plate 12 gradually enters the main water supply pipe 3, the first connecting member 1 is also gradually flattened. Finally, the connecting plate 12 completely enters the main water supply pipe 3 and rests on the inner pipe wall of the main water supply pipe 3.

[0078] The second connecting member 2 is threadedly connected to the first connecting member 1, and the pipe wall of the main water supply pipe 3 is sealed and clamped between the second connecting member 2 and the connecting plate 12. Specifically, after the first connecting member 1 is installed in the opening 31, the second connecting member 2 is threadedly tightened on the first connecting member 1 and the area around the opening 31 is sealed.

[0079] Finally, the drip irrigation pipe is connected to the corresponding second connecting piece 2 .

[0080] By providing a connecting plate on the first connecting piece and providing an inserting portion extending outward on the connecting plate, during use, the operator can drill a hole on the main water supply pipe to form an opening according to the irrigation requirements at the construction site, then insert the inserting portion of the first connecting piece into the opening and rotate it, and rely on the guidance of the inserting portion to enable the connecting plate to rotate into the main water supply pipe and abut against the inner pipe wall of the main water supply pipe, and then the second connecting piece is threadedly connected to the first connecting piece. At this time, the pipe wall of the main water supply pipe around the opening will be sealed and clamped between the second connecting piece and the connecting plate to achieve sealing of the opening, and the drip irrigation pipe can be connected to the corresponding second connecting piece to achieve communication with the main water supply pipe to achieve water supply; since the first connecting piece can be installed on the main water supply pipe on site, it is convenient for the operator to install it on site. In this way, the corresponding position of the main water supply pipe can be drilled on site to install the pipe connector according to the distribution requirements of the actual irrigation area, so that the operator can assemble the pipe connector to the main water supply pipe on site to improve the convenience of on-site installation, thereby improving the flexibility and convenience of use.

[0081] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
