Problems solved by technology

[0003] At present, in domestic water-fertilizer integrated water-saving irrigation, most of the drip seepage pipe belts with inner patches or drippers in the form of inlaid stable flow channels are used, but the inner patches of the inner patch drip seepage pipe belts are glued to the inner wall of the pipe belt. The contact point is very small. During use, it is easy to age and deform due to high temperature in the sun, causing the inner patch to fall off; the drip seepage tube with the inner dripper is designed to be narrow and short, and the water pressure in the tube is small, so there is a problem during use. The clogging of the dripper is serious, which affects the service life of the infiltration pipe belt. At the same time, the compensating inner dripper produced in China has not been able to solve the compensation effect of the inner dripper because of the poor control of the thickness uniformity and hardness of the elastomer material. Causes uneven water seepage in each section, affecting irrigation effect

Abstract

The invention provides a compensating infiltration pipe belt with oblique puncture seams inlaid with elastic body sleeves and a preparation method thereof. Composition, the forming pipe belt is co-extruded and laminated by layer A and layer B, layer A is made of EVA material, layer B is made of polyethylene material, and the structure is A+B+A from the inside to the outside; the inner sleeve of the elastomer It is injection-molded with EVA elastomer material or TPE elastomer material, and embedded in the molding pipe; the elastic inner sleeve and the molding pipe are inlaid with a water outlet oblique slit, and the width of the oblique slit can be adjusted according to the requirement of dripping water. , the direction of the oblique stabbing is along the water. The inlaid elastomer sleeve provided by the present invention can be used for embedding seepage in shallow soil and irrigating plants with integrated water, fertilizer and medicine. Well, it solves the problem of easy blockage of the original drip irrigation pipe.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation and water delivery, and in particular relates to a compensating drip seepage belt with an elastic body sleeve strip inside and a preparation method thereof. Background technique [0002] In modern agricultural planting, water-fertilizer integrated water-saving irrigation refers to transporting water, chemical fertilizers, and pesticides together and slowly dripping them into the soil at the roots of crops according to the water requirements of crops, avoiding the loss of water, fertilizer, and pesticides during the transportation process. Leakage, volatilization and waste can save water and fertilizer to the greatest extent and reduce costs, which is of great significance in water-scarce areas. [0003] At present, in domestic water-fertilizer integrated water-saving irrigation, most of the drip seepage pipe belts with inner patches or drippers in the form of inlaid stable flow cha...
