Description

Technical Field

[0001] This utility model relates to the field of drip irrigation tape technology, and in particular to a wear-resistant multi-layer composite drip irrigation tape. Background Technology

[0002] Drip irrigation technology is a highly efficient water-saving irrigation method. Its core component, drip irrigation tape, delivers water and nutrients directly and evenly to the roots of crops through internal channels and drip holes. Drip irrigation tape is a thin-walled plastic tube with built-in precision channels and drip holes, and belongs to water-saving irrigation equipment.

[0003] It delivers water and fertilizer in the form of droplets or streams slowly, evenly, and directly to the soil near the crop roots through its drip holes, minimizing evaporation and runoff losses, thereby achieving efficient water and fertilizer use and promoting crop growth.

[0004] Based on the aforementioned technologies, the applicant believes that existing drip irrigation tapes are mostly single-layer or double-layer structures, which generally have poor wear resistance in actual use. They are easily damaged by friction with the ground during laying and recycling, leading to water leakage. This seriously affects the service life and irrigation efficiency of the drip irrigation tape, increases the cost of use for farmers, and makes the installation and disassembly of the drip irrigation tape inconvenient. In response to the above problems, we have launched a wear-resistant multi-layer composite drip irrigation tape. Utility Model Content

[0005] This utility model discloses a wear-resistant multi-layer composite drip irrigation tape, which aims to solve the technical problems of poor wear resistance, easy damage during laying and recycling due to friction with the ground, resulting in water leakage, seriously affecting the service life and irrigation efficiency of the drip irrigation tape, increasing the cost of use for farmers, and the inconvenience of installing and disassembling the drip irrigation tape.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wear-resistant multi-layer composite drip irrigation tape includes a drip irrigation tape body, which is composed of three layers: an outer protective layer, a middle reinforcing layer, and an inner functional layer, from the outside to the inside. The three layers are integrally formed by co-extrusion. A drip tube mechanism is provided on the outer side of the drip irrigation tape body. The drip tube mechanism includes an installation component and a positioning component, which cooperate with each other. The installation component includes connecting rings, which are symmetrically sleeved on the outer side of the drip irrigation tape body. A support plate is fixedly connected to the top of the two connecting rings. A fixing frame is fixedly connected to the top of the support plate. The fixing frame has symmetrical slots on the top. A rotating block is fixedly connected to one side of the top of the support plate. A pressing plate is rotatably connected to the top of the rotating block. A positioning groove is symmetrically opened at the bottom of the pressing plate. An insertion rod is fixedly connected to the other side of the pressing plate. An insertion hole is opened inside the insertion rod.

[0008] By designing a drip irrigation mechanism, the overall quality of the drip irrigation tape can be greatly improved, especially in terms of wear resistance, stability, and prevention of algae growth. At the same time, the drip irrigation tape can be quickly installed and fixed, improving installation efficiency. It has a simple structure and is highly practical.

[0009] In a preferred embodiment, the positioning component includes a fixing frame fixedly connected to the top side of the support plate, a slot being provided on the inner side of the fixing frame, a slide rod being slidably connected inside the fixing frame, a limit plate being fixedly connected to the outer side of the slide rod, and a spring being sleeved on the outer side of the slide rod.

[0010] The positioning components prevent it from loosening due to water pressure vibration or accidental contact, ensuring the reliability and sealing of the connection process and enabling rapid installation and fixation of the drip irrigation tape.

[0011] In a preferred embodiment, the inner functional layer is made of linear low-density polyethylene mixed with color masterbatch, forming the inner wall of the drip irrigation tape, which serves to deliver water, resist environmental stress cracking, and prevent algae growth. The intermediate reinforcing layer is composited outside the inner functional layer and is made of high-density polyethylene, which serves to support the pipe structure and enhance tensile and compressive strength. The outer protective layer is the outermost layer and is made of polyethylene material with added abrasion-resistant agents, which serves to protect against mechanical wear and scratches.

[0012] The inner functional layer uses linear low-density polyethylene and color masterbatch to ensure the smoothness of the inner wall and resistance to chemical corrosion, effectively preventing algae growth and orifice blockage; the middle reinforcing layer uses high-density polyethylene to provide a high-strength and rigid skeleton for the pipe body, ensuring that the drip irrigation tape is not easily flattened or deformed under the pressure of the soil covering, and that the water flow is always unobstructed; the outer protective layer uses polyethylene with added wear-resistant agents, which directly faces the soil friction, greatly enhancing the wear resistance of the product and extending its service life in rough fields.

[0013] In a preferred embodiment, drip heads are fixedly connected at equal intervals to both sides of the bottom of the drip tape body.

[0014] By equidistantly placing drip heads on both sides of the bottom of the drip irrigation tape, bidirectional and uniform water output is achieved. This layout expands the irrigation coverage of a single drip irrigation tape, improves irrigation uniformity, reduces the amount of tape used in the field, lowers user input costs, and allows water and fertilizer to be delivered more precisely to both sides of the crop roots, resulting in higher absorption efficiency.

[0015] In a preferred embodiment, the interior of the fixing frame is provided with a supporting square tube.

[0016] The supporting square tube inside the fixing frame plays a crucial internal support role, preventing the fixing frame from deforming or crushing the drip irrigation tape body, protecting the internal flow channel structure, and ensuring the long-term sealing and structural integrity of the connection parts.

[0017] In a preferred embodiment, a pull block is fixedly connected to one end of the slide rod, and the pull block is made of anti-slip rubber.

[0018] The anti-slip rubber surface increases friction, making it easier and more convenient for users to pull out the slider to release the press plate, even when their hands are wet or muddy, thus improving the user experience.

[0019] The wear-resistant multi-layer composite drip irrigation tape provided by this utility model has the following advantages:

[0020] Firstly, the drip irrigation mechanism greatly improves the overall quality of the drip irrigation tape, especially in terms of wear resistance, stability, and prevention of algae growth. At the same time, the drip irrigation tape can be quickly installed and fixed, improving installation efficiency. It has a simple structure and is highly practical.

[0021] Secondly, by equidistantly placing drip heads on both sides of the bottom of the drip irrigation tape, bidirectional and uniform water output is achieved. This layout expands the irrigation coverage of a single drip irrigation tape, improves irrigation uniformity, reduces the amount of tape used in the field, lowers user input costs, and allows water and fertilizer to be delivered more precisely to both sides of the crop roots, resulting in higher absorption efficiency. The supporting square tube inside the fixing frame plays a crucial internal support role, preventing the fixing frame from deforming or crushing the drip irrigation tape body, protecting the internal flow channel structure, and ensuring the long-term sealing and structural integrity of the connection points. The anti-slip rubber surface increases friction, making it easier and more effortless for users to pull out the slider to release the pressing plate, even with wet or muddy hands, thus improving the user experience.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] The wear-resistant multi-layer composite drip irrigation tape disclosed in this utility model is mainly used in drip irrigation scenarios.

[0029] Reference Figure 1 - Figure 4A wear-resistant multi-layer composite drip irrigation tape includes a drip irrigation tape body 1, which is divided into three layers: an outer protective layer 2, a middle reinforcing layer 3, and an inner functional layer 4, from the outside to the inside. The three layers are integrally formed by co-extrusion. A drip tube mechanism is provided on the outside of the drip irrigation tape body 1. The drip tube mechanism includes an installation component and a positioning component, which are used in conjunction with each other. The installation component includes connecting rings 51, which are symmetrically sleeved on the outside of the drip irrigation tape body 1. A support plate 52 is fixedly connected to the top of the two connecting rings 51. A fixing frame 53 is fixedly connected to the top of the support plate 52. The fixing frame 53 has symmetrical slots 54 on the top. A rotating block 55 is fixedly connected to one side of the top of the support plate 52. A pressing plate 56 is rotatably connected to the top of the rotating block 55. A positioning groove 57 is symmetrically opened at the bottom of the pressing plate 56. An insertion rod 58 is fixedly connected to the other side of the pressing plate 56. An insertion hole 59 is opened inside the insertion rod 58. The positioning component includes a fixing frame 61, which is fixedly connected to the top side of the support plate 52. A slot 62 is provided on one side of the inside of the fixing frame 61. A slide rod 63 is slidably connected inside the fixing frame 61. A limit plate 64 is fixedly connected to the outside of the slide rod 63. A spring 65 is sleeved on the outside of the slide rod 63. The inner functional layer 4 is made of linear low-density polyethylene and color masterbatch, forming the inner wall of the drip irrigation tape. It plays a role in water delivery, resisting environmental stress cracking, and preventing algae growth. The intermediate reinforcing layer 3 is composited outside the inner functional layer 4 and is made of high-density polyethylene. It plays a role in supporting the pipe structure and enhancing tensile and compressive strength. The outer protective layer 2 is the outermost layer and is made of polyethylene material with added abrasion-resistant agents. It plays a role in protecting against mechanical wear and scratches.

[0030] In this embodiment: The pressing plate 56 is rotated, and its positioning groove 57 engages with the slot 54, causing the bottom of the pressing plate 56 to fit against the top of the supporting square tube 8. At this time, the insertion rod 58 is inserted into the slot 62, and under the action of the spring 65, the sliding rod 63 is inserted into the insertion hole 59, completing the fixed installation of the drip irrigation tape body 1. Irrigation water is transported from the branch pipe through the dripping mechanism into the inner functional layer 4 of the drip irrigation tape body 1. The water flows within the tape and finally drips evenly from the dripping heads 7 on both sides of the bottom. During this process, the outer protective layer 2 resists soil friction, the middle reinforcing layer 3 withstands internal and external pressure to maintain the tube shape, and the inner functional layer 4 ensures smooth water flow and prevents algae growth. The drip irrigation mechanism greatly improves the overall quality of the drip irrigation tape, especially in terms of wear resistance, stability, and preventing algae growth. Simultaneously, the drip irrigation tape can be quickly installed and fixed, improving installation efficiency. It has a simple structure and strong practicality.

[0031] The above technical solution suffers from poor wear resistance, making it prone to damage during installation and recycling due to friction with the ground, leading to leaks and severely impacting the lifespan and irrigation efficiency of the drip irrigation tape, increasing farmers' operating costs, and causing inconvenience in installing and disassembling the tape. To address these issues, the specific operation is as follows:

[0032] Reference Figure 1 - Figure 4 In a preferred embodiment, drip heads 7 are fixedly connected at equal intervals on both sides of the bottom of the drip tape body 1. A supporting square tube 8 is provided inside the fixing frame 53. A pulling block 66, made of anti-slip rubber, is fixedly connected to one end of the sliding rod 63.

[0033] In this embodiment, drip heads 7 are equidistantly positioned on both sides of the bottom of the drip irrigation tape body 1, achieving bidirectional and uniform water output. This layout expands the irrigation coverage of a single drip irrigation tape, improves irrigation uniformity, reduces the amount of tape used in the field, lowers user input costs, and allows water and fertilizer to be delivered more precisely to both sides of the crop roots, resulting in higher absorption efficiency. The supporting square tube 8 inside the fixing frame 53 plays a crucial internal support role, preventing the fixing frame 53 from deforming or crushing the drip irrigation tape body 1, protecting the internal flow channel structure, and ensuring the long-term sealing and structural integrity of the connection parts. The anti-slip rubber surface increases friction, making it easier and more effortless for users to pull out the slide bar 63 to release the pressing plate 56, even when their hands are wet or muddy, thus improving the user experience.

[0034] Working principle: When connection is required, the supporting square tube 8 is placed inside the fixing frame 53. Then, the pressing plate 56 is rotated, and the positioning groove 57 of the pressing plate 56 is engaged with the inside of the slot 54, so that the bottom of the pressing plate 56 is in contact with the top of the supporting square tube 8. At this time, the insertion rod 58 is inserted into the inside of the slot 62. Under the action of the spring 65, the sliding rod 63 is inserted into the inside of the insertion hole 59, completing the fixed installation of the drip irrigation tape body 1. The irrigation water is delivered from the branch pipe through the drip irrigation mechanism into the inner functional layer 4 of the drip irrigation tape body 1. The water flows inside the tape and finally drips evenly from the drip heads 7 on both sides of the bottom. During this process, the outer protective layer 2 resists soil friction, the middle reinforcing layer 3 withstands internal and external pressure to maintain the tube shape, and the inner functional layer 4 ensures smooth water flow and prevents algae growth.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
