A spiral textured anti-bite drip irrigation tape

Abstract

This utility model provides a spiral-textured anti-bite drip irrigation tape, relating to the field of drip irrigation tape technology. It includes a drip irrigation tape body with a continuous spiral textured outer surface. Multiple drip holes are spaced axially at the top of the drip irrigation tape body. A reinforcing layer is embedded inside the drip irrigation tape body. An anti-bite coating is applied to the outer surface of the drip irrigation tape body. The continuous spiral textured outer surface interferes with the direction of force applied by animals during biting, forcing rodent teeth to slide along the textured surface during biting, making it difficult for them to stably bite the tube body, significantly reducing the risk of bite-through. Simultaneously, a friction resistance layer is formed on the surface of the spiral textured surface through a frosting process. The frosted surface increases the sliding resistance when animal teeth contact, further weakening the biting and destructive force. The rough texture enhances the anti-slip performance of the drip irrigation tape surface, reducing accidental displacement caused by friction during installation.

Description

Technical Field

[0001] This utility model relates to the field of drip irrigation tape technology, and in particular to a spiral textured anti-biting drip irrigation tape. Background Technology

[0002] Existing drip irrigation tapes mostly use smooth pipe walls or simple corrugated structures, which are easily damaged by rodents and insects when used in the field, leading to problems such as leakage and uneven irrigation. Traditional solutions include thickening the pipe walls or adding chemical repellents, but these are costly and pose environmental pollution risks. Therefore, we propose a spiral-textured anti-chewing drip irrigation tape. Utility Model Content

[0003] The purpose of this invention is to provide a spiral textured anti-biting drip irrigation tape to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spiral textured anti-bite drip irrigation tape includes a drip irrigation tape body, the outer surface of which is surrounded by a continuous spiral texture, the top of which is provided with a plurality of drip holes spaced axially, a reinforcing layer is embedded inside the drip irrigation tape body, and the outer surface of which is coated with an anti-bite coating.

[0006] The technical effects of adopting the above-mentioned further solutions are as follows: the continuous undulating structure of the spiral ridge interferes with the stability of the force applied by the animal when biting, and combined with the chemical barrier effect of the anti-biting coating, a synergistic physical and chemical protection is formed, which significantly reduces the risk of damage caused by animal biting; the internal reinforcing layer enhances the toughness of the pipe structure through composite materials, and improves the tear resistance while maintaining the flexibility of the drip irrigation tape.

[0007] As a preferred embodiment of this utility model, 3-5 support feet are arranged around the periphery of the plurality of drip holes, the support feet being more than 2mm in height and integrally formed from HDPE material.

[0008] The technical advantages of adopting the above-mentioned further solutions are: the support feet surrounding the drip holes form a stable support frame, preventing the drip holes from directly contacting the ground or hard objects, thus avoiding deformation or blockage; and the use of high-density polyethylene material in one piece ensures that the support feet are lightweight and have long-term weather resistance, adapting to complex field environments.

[0009] As a preferred embodiment of this utility model, a protective cover is fixedly connected to the top of the support foot, and the protective cover covers the drip hole and maintains a water-guiding gap of more than 1mm between the protective cover and the drip hole.

[0010] The technical effects of adopting the above-mentioned further solution are: the protective cover covers the drip hole, effectively blocking foreign objects such as mud and debris from directly entering the drip hole and preventing irrigation blockage; the water guide gap allows the water to spread naturally when it flows through, forming a uniform irrigation coverage area and improving water resource utilization.

[0011] As a preferred embodiment of this utility model, the width of the gap groove formed between the support feet is greater than 1 mm, and the gap groove is evenly distributed along the circumference of the drip hole to guide the water flow to diffuse towards the ground.

[0012] The technical effect of adopting the above-mentioned further solution is that the circumferentially evenly distributed gaps guide water flow to infiltrate into the soil in different directions, avoiding local water accumulation or uneven irrigation.

[0013] As a preferred embodiment of this utility model, the spiral textured surface is sanded to form a friction resistance layer.

[0014] The technical effects of adopting the above-mentioned further solutions are: the frosted surface increases the sliding resistance when animal teeth come into contact, further weakening the biting and destructive force; the rough texture enhances the anti-slip performance of the drip irrigation tape surface, reducing accidental displacement caused by friction during the laying process.

[0015] As a preferred embodiment of this utility model, the reinforcing layer is a co-extruded composite layer of nylon reinforcing mesh and high-density polyethylene.

[0016] The technical effect of adopting the above-mentioned further solution is that the co-extrusion composite of nylon reinforcing mesh and high-density polyethylene significantly improves tear resistance and axial tensile strength.

[0017] As a preferred embodiment of this utility model, the anti-biting coating is a bittering agent composite layer.

[0018] The technical effects of adopting the above-mentioned further solutions are: the bittering agent component repels rodents to actively stay away through taste stimulation, forming a long-term protection at the biological behavior level; the coating adheres tightly to the surface of the drip irrigation tape, and maintains an effective protection cycle even under rain or sun exposure.

[0019] As a preferred embodiment of this utility model, the surface of the anti-bite coating is covered with a UV protection layer, which is a composite coating of nano-titanium dioxide and polyurethane.

[0020] The technical effects of adopting the above-mentioned further solutions are: the nano-titanium dioxide and polyurethane composite layer effectively absorb ultraviolet rays, delaying the photo-aging degradation of the anti-biting coating; the polyurethane outer layer provides wear-resistant protection, reducing mechanical damage to the coating during field operations or transportation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. In this utility model, the outer surface of the drip irrigation tape is surrounded by continuous spiral ridges, which interfere with the direction of force applied by animals when biting, forcing the rodent's teeth to slide along the ridges during biting, making it impossible for them to stably bite the tube body, thus significantly reducing the risk of biting through. At the same time, the surface of the spiral ridges is treated with sanding to form a friction resistance layer. The sanded surface increases the sliding resistance when the animal's teeth come into contact, further weakening the biting and destructive force. The rough texture enhances the anti-slip performance of the drip irrigation tape surface, reducing accidental displacement caused by friction during the laying process.

[0023] 2. In this utility model, the design of the supporting feet and protective cover around the drip hole allows the supporting feet to lift the drip hole off the ground, preventing the drip hole from directly contacting the soil or gravel. At the same time, the protective cover covers the drip hole, blocking foreign objects such as fallen leaves and insects from entering. The gap between the protective cover and the drip hole allows the water flow to diffuse naturally. A groove is formed between the supporting feet, and the circumferential distribution of the groove guides the water flow to penetrate into the soil in different directions, avoiding local water accumulation or uneven irrigation.

[0024] 3. In this utility model, through the design of a reinforcing layer, an anti-bite coating, and a UV protection layer, the composite structure of the nylon reinforcing layer and HDPE significantly improves tear resistance and axial tensile strength, ensuring that the pipe body is flexible and durable while resisting mechanical damage in the field; the anti-bite coating uses bittering agents to repel animal bites, and combined with its tight adhesion characteristics, it achieves long-term biological protection against rain and sun exposure; the superimposed UV protection layer uses nano-titanium dioxide to absorb ultraviolet rays and delay coating aging, while the polyurethane surface layer enhances wear resistance. The three work together to form a comprehensive protection system of mechanical reinforcement, biological barrier, and environmental tolerance, which greatly extends the service life of the drip irrigation tape and reduces maintenance costs.

[0034] Example 1

[0035] like Figure 1-4As shown, this utility model provides a technical solution: a spiral textured anti-biting drip irrigation tape, comprising a drip irrigation tape body 1 made of high-density polyethylene (HDPE), the outer surface of which is formed with continuous spiral textures 2 by an extrusion process. The spiral textures 2 surround the surface of the tape body at an inclined angle, forming a uniform wave-like undulating structure. Multiple drip holes 3 are distributed axially at intervals on the top of the drip irrigation tape body 1. Each drip hole 3 is surrounded by three arc-shaped support feet 4. The support feet 4 are integrally extruded with the drip irrigation tape body 1, and their height is slightly higher than the drip hole 3. A protective cover 401 is fixedly connected to the top of the support feet 4. The protective cover 401 covers the drip hole 3 and maintains a water-conducting gap of more than 1 mm between it and the drip hole 3. It effectively blocks foreign objects such as mud, sand and debris from directly entering the drip hole 3 and prevents irrigation blockage. The water-conducting gap allows water to spread naturally when it passes through, forming a uniform irrigation coverage area and improving water resource utilization. The gap groove 402 formed between the support legs 4 has a width of more than 1 mm. The gap groove 402 is evenly distributed around the drip hole 3 and is used to guide the water flow to spread to the ground. The even distribution of the gap groove 402 around the circumference guides the water flow to penetrate into the soil in different directions, avoiding local water accumulation or uneven irrigation.

[0036] Example 2

[0037] like Figure 1-4 As shown, this utility model provides a technical solution: a spiral textured anti-chewing drip irrigation tape. The surface of the spiral texture 2 is treated with a frosted finish to form a friction resistance layer. The frosted surface increases the sliding resistance when animal teeth come into contact, further weakening the chewing and destructive force. The rough texture enhances the anti-slip performance of the drip irrigation tape surface, reducing accidental displacement caused by friction during installation. The reinforcing layer 5 is a co-extruded composite layer of nylon reinforcing mesh and high-density polyethylene. The co-extruded composite of nylon reinforcing mesh and high-density polyethylene significantly improves tear resistance and axial tensile strength. The anti-chewing coating 6 is a bittering agent composite. The first layer contains a bittering agent that stimulates the taste buds, repelling rodents and creating long-lasting protection at the biological behavioral level. The coating adheres tightly to the surface of the drip irrigation tape, maintaining effective protection even under rain or sun exposure. The anti-bite coating 6 is covered with a UV protection layer 7, which is a composite coating of nano-titanium dioxide and polyurethane. This composite layer effectively absorbs ultraviolet rays, delaying the photo-aging and degradation of the anti-bite coating 6. The outer polyurethane layer provides wear-resistant protection, reducing mechanical damage to the coating during field operations or transportation.

[0038] The working process of this utility model is as follows: When using a spiral textured anti-biting drip irrigation tape, it includes a drip irrigation tape body 1. The outer surface of the drip irrigation tape body 1 is surrounded by continuous spiral textures 2. The continuous undulating structure of the spiral textures 2 interferes with the stability of the force applied by the animal when biting. The surface of the spiral textures 2 is treated with a sandblasting process to form a friction resistance layer. The sandblasted surface increases the sliding resistance when the animal's teeth come into contact, further weakening the biting and destructive force. The rough texture enhances the anti-slip performance of the drip irrigation tape surface and reduces accidental displacement caused by friction during installation. The top of the drip irrigation tape body 1 is along the axis... Multiple drip holes 3 are spaced apart. Each drip hole 3 is surrounded by 3-5 support feet 4, each support foot 4 being more than 2mm high and integrally molded from HDPE material. A protective cap 401 is fixedly connected to the top of each support foot 4. The protective cap 401 covers the drip hole 3, maintaining a water-conducting gap of more than 1mm between itself and the drip hole 3. The support feet 4 surrounding the drip hole 3 form a stable support frame, preventing the drip hole 3 from directly contacting the ground or hard objects, thus avoiding deformation or blockage. The protective cap 401 effectively blocks mud, sand, debris, and other foreign objects from directly contacting the drip hole 3. The dripping holes 3 prevent irrigation blockage; the water-conducting gaps allow water to spread naturally as it passes through, forming a uniform irrigation coverage area and improving water resource utilization; a nylon fiber mesh reinforcement layer 5 is co-extruded and embedded inside the drip irrigation tape body 1. The nylon mesh and HDPE substrate are fused together at high temperature to form a composite structure with a seamless interface, significantly improving the tear resistance and axial tensile strength of the pipe body, while maintaining overall flexibility to adapt to field bending requirements; the outer surface of the drip irrigation tape is coated with a bittering agent composite coating. The bittering agent is evenly adhered to the spiral ridges 2 and the surface of the pipe body through spraying or impregnation processes, forming a chemical barrier layer; the bitter components in the coating stimulate the taste buds of animals to avoid biting behavior, and are tightly adhered to the HDPE substrate through adhesives, ensuring long-term resistance to water erosion and sun exposure stability; a UV protection layer 7 composed of nano-titanium dioxide and polyurethane is further coated on the outer surface of the anti-biting coating 6. The nano-titanium dioxide absorbs ultraviolet rays through photocatalysis, delaying the photo-oxidative degradation of the underlying coating; the polyurethane component forms a dense and wear-resistant surface layer, reducing mechanical damage during field operations or transportation and extending the service life of the overall coating.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
