Description

Technical Field

[0001] This utility model relates to the field of micro-spray tape technology, specifically a thickened irrigation pipe body. Background Technology

[0002] In agricultural irrigation, drip irrigation or micro-sprinkler irrigation is often required in greenhouse planting, cotton planting and other scenarios, especially in Xinjiang and other regions where the climate is dry and ultraviolet radiation is strong. During the irrigation process, the pipe body needs to be perforated to install sprinklers or directly punched holes for micro-sprinkler irrigation.

[0003] The existing irrigation pipes have the following problems: 1. The overall thickness of the tube is uniform, but the perforated area is not wear-resistant and has insufficient pressure resistance, making it prone to breakage after long-term use; 2. When laying long-distance pipes, workers need to accurately locate and drill spray holes or install nozzles on the upper part of the pipe. Because the pipe is cylindrical and a single color, it is difficult to quickly and accurately determine the drilling location in the field, resulting in low installation efficiency and inconsistent nozzle orientation. 3. The pipe body with uniform wall thickness has limited overall pressure resistance. When subjected to local pressure from heavy objects (such as stones or agricultural machinery tires), it is very easy to be flattened, deformed, or even broken, affecting the water flow. Utility Model Content

[0004] The purpose of this invention is to provide an irrigation pipe body with a thickened middle section to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a thickened irrigation pipe body, including a pipe body, on the inner wall of the pipe body along its length direction, there is a raised thickened area, the thickened area is provided with micro-spray holes or nozzle mounting holes; the outer surface of the thickened area is provided with two parallel positioning lines, the positioning lines extending along the length direction of the pipe body.

[0006] By adopting the above technical solution, the wall thickness of the thickened area is significantly increased compared to the non-thickened area of ​​the pipe, thereby enhancing the mechanical strength and compressive strength of this area and greatly extending the service life of the pipe. Compared to the overall thickening of the pipe wall, the local thickening design ensures the strength of key areas while maximizing material savings, reducing production costs, and maintaining the overall flexibility of the pipe, facilitating winding and laying. The positioning line can quickly and accurately locate the positions of micro-spraying holes or nozzle mounting holes.

[0007] Preferably, the thickened area is located on the upper part of the tube body, and its cross-sectional profile is a continuous and smooth convex shape.

[0008] By adopting the above technical solution, this design can make the thickened area more uniformly stressed, avoid stress concentration, and reduce the resistance of water flow in the pipe body, thus ensuring stable irrigation water pressure.

[0009] Preferably, the positioning line is a colored line, the color of which is clearly distinguishable from the background color of the tube.

[0010] By adopting the above technical solutions, colored lines provide a clear and reliable visual and tactile reference for laying and installation, thereby improving laying efficiency.

[0011] Preferably, the tube body is a multi-layer composite structure, including at least an inner layer and an outer layer, and the thickened area is formed by local thickening of the outer layer.

[0012] By adopting the above technical solution, this design can ensure the strength of the nozzle area while avoiding the thickening of the inner structure from affecting the water flow channel inside the pipe, thus ensuring stable irrigation flow.

[0013] Preferably, the inner layer is a dark-colored light-blocking layer and the outer layer is a light-colored reflective layer.

[0014] By adopting the above technical solution, the inner dark-colored shading layer can effectively block sunlight from penetrating the pipe, inhibit the growth of algae and biological slime inside the pipe, and reduce the risk of micro-spray hole blockage; the outer light-colored reflective layer can reduce the absorption of solar radiation heat by the pipe, prevent the pipe from aging due to high temperature, extend the service life of the hose, and is especially suitable for use in outdoor high-temperature environments.

[0015] Preferably, the two sides of the outer surface of the thickened area are smoothly connected to the non-thickened area through inclined transition slopes.

[0016] By adopting the above technical solution, the transition slope can avoid the right-angle connection between the thickened area and the non-thickened area, disperse the stress at the connection between the thickened area and the non-thickened area, and avoid warping and damage problems.

[0017] Preferably, the tube body and its thickened area and positioning line are integrally formed.

[0018] By adopting the above technical solutions and using an integrated molding process and co-extrusion molding process, the connection strength between the thickened area, positioning line and pipe body is ensured, and it is a solid whole without splicing gaps, thus avoiding the risk of leakage, while improving production efficiency and reducing production costs.

[0019] The beneficial effects of this utility model are: 1. By creating an axially extending thickened zone on the hose body, and opening spray holes or installing nozzles within this thickened zone, the weakest point of the hose, which is most susceptible to damage, is fundamentally strengthened. The thickened zone effectively disperses concentrated stress caused by trampling and squeezing, preventing tearing around the spray holes and flattening of the hose body, thus significantly extending the service life of the hose. Compared to a solution that thickens the entire hose wall, this utility model adopts a localized thickening design, which, while ensuring the strength of key areas, saves materials to the maximum extent, reduces production costs, and maintains the overall flexibility of the hose, facilitating winding and laying.

[0020] 2. Two parallel positioning lines set on the outer surface of the thickened area provide a clear and reliable visual and tactile reference for laying and installation. Construction personnel can quickly find the center line of the thickened area along the positioning lines, thereby accurately opening micro-spray holes or installing sprinklers, ensuring that the sprinkler directions are consistent, improving construction efficiency and irrigation uniformity.

[0021] 3. Through a one-piece molding process, the pipe body, thickened area, and positioning lines are combined into a robust whole, without any seams, thus avoiding the risk of leakage. The multi-layered composite structure and transitional bevel design further optimize the product's anti-aging properties, light-shielding and algae-proofing capabilities, and structural reliability.

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] Example 1 like Figure 1 and Figure 2As shown, an irrigation pipe body 1 with a thickened center includes a flexible hose that can be formed using extrusion, co-extrusion, or other processes. The hose body 1 has a multi-layered composite structure, comprising at least an inner layer 11 and an outer layer 12. The inner layer 11 is a dark-colored light-blocking layer, with carbon black added to the raw material to effectively block sunlight penetration and inhibit algae growth inside the pipe. The outer layer 12 is a light-colored reflective layer, with titanium dioxide added to the raw material to reduce solar radiation heat absorption and improve anti-aging properties.

[0026] like Figure 3 and Figure 4 As shown, a thickened area 2 is provided on the inner wall of the pipe body 1 along its length. The thickened area 2 is formed by a local thickening of the outer layer 12, and its cross-sectional profile is a continuous and smooth protrusion, such as square, arc, trapezoidal, etc. The height of the thickened area 2 is 30%-35% of the wall thickness of the non-thickened area 2 of the pipe body 1. The two sides of the outer surface of the thickened area 2 are smoothly connected to the non-thickened area 2 through inclined transition slopes 4, which can disperse the stress at the joint and avoid warping and damage. The thickened area 2 is preferably located in the upper part of the circumference of the pipe body 1. This is because during laying, the nozzles or sprayers usually spray upward or to the side. Placing the thickened area 2 in the upper part strengthens the pressure-bearing and impact-sensitive areas.

[0027] like Figure 1 As shown, the thickened area 2 is provided with micro-spray holes or nozzle mounting holes, and the outer surface of the thickened area 2 is provided with two parallel positioning lines 3, which extend along the length of the tube body 1. The positioning lines 3 are colored lines, made of weather-resistant masterbatch, and the color is red, which forms a clear distinction from the white background of the outer layer 12 of the tube body 1.

[0028] The tube body 1 and its thickened area 2 and positioning line 3 are integrally formed by co-extrusion molding process to ensure the connection strength and sealing reliability of each structure, avoid the problem of falling off or breaking during use, and improve production efficiency.

[0029] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
