Cylindrical microporous labyrinth drip irrigation tape and processing method

Abstract

The invention provides a barrel-shaped micropore labyrinth drip irrigation tape, consisting of a drip irrigation tape water delivery passage and a labyrinth runner, wherein the side face of the drip irrigation tape water delivery passage is provided with the micropore labyrinth runner formed by filling ropes, the radial part, adjacent to the water delivery passage, of the micropore labyrinth runner is provided with inner water outlets uniformly, and outer water outlets in staggered arrangement with the inner water outlets extend to seams of the drip irrigation tape. The processing method is characterized in that while the drip irrigation tape water delivery passage is extruded, two cotton ropes penetrate into extrusion die heads to serve as labyrinth fillings, the extruded thin wall barrel sleeves outside the cotton ropes and are extruded into an inner 8 shape font and an outer 8 shape, the large 8 shape at the outer side forms the drip irrigation tape water delivery passage, and the small 8 shape at the inner side respectively wraps the two cotton ropes in a plastic film for forming a barrel-shaped micropore labyrinth. The technical progress effects are that the anti-blocking performance is greatly improved, drip irrigation system filtering equipment can be simplified, and the operation energy consumption of a drip irrigation system is reduced. When the irrigation specification of the drip irrigation tape needs to be changed, no hardware in a production line needs to be changed, and only the cotton ropes with proper diameters or water outlets with proper number are selected.

Description

technical field [0001] The invention relates to a cylindrical microporous labyrinth drip irrigation belt and a processing method, in particular to a production method of a drip irrigation belt suitable for field crop buried application, and belongs to the technical field of water-saving irrigation agricultural equipment. Background technique [0002] Various drip irrigation pipes and drip irrigation belts currently used in the field of agricultural micro-irrigation technology are equipped with a set of labyrinths at the front of each drip outlet to damp and reduce the internal pressure of the drip irrigation pipe / belt, and to balance the output of each drip outlet. Pressure and water output, so as to ensure that the water output of each drip outlet is basically the same within a certain laying length of the drip irrigation pipe / belt. The labyrinth is roughly divided into two categories, one is formed separately, and then embedded in the drip irrigation pipe / belt, or inserted...
