Embodiment 1

[0037] figure 1 Shown is a schematic diagram of the coating structure of the labyrinth drip irrigation belt widely used at present with the method of the present invention, the seepage side seam 4 of the drip irrigation belt is located in the middle of the filter mantle, and the filter mantle is heat-sealed and pressed by the upper and lower two-layer coating Composed of stitching or stitching, the upper layer is a fiber layer of water-permeable material, such as non-woven fabric, open foam, etc. The following is a water-blocking material, such as ordinary plastic film. A preferred example given by the present invention is to choose water-permeable fiber material non-woven fabric or open foam plastic for both top and bottom, and a water-blocking film 2 is arranged on the surface of the water-permeable fiber below. And in order to allow the irrigation water to concentrate on the root system of the above crops, the extended side of the lower water-blocking material layer of the...

Abstract

The invention provides a coated drip irrigation tube/belt, which is simple in structure and low in manufacturing cost, and a production method thereof, and aims to solve the problem that a buried drip irrigation tube/belt blocks a water outlet. According to the technical scheme, the coated drip irrigation tube/belt is formed by coating a common drip irrigation tube/belt body with a filter covering film, an axial lower half of the filter covering film is a waterstop material layer, an upper half of the filter covering film is a water-permeable material layer, the upper layer and the lower layer are adhered or sewn oppositely. A maze water outlet of the drip irrigation tube/belt is arranged at the center of the water-permeable material layer, and the waterstop material layer is arranged below the common drip irrigation tube/belt. The protective film is added outside the common drip irrigation tube/belt, so that the service life of the drip irrigation tube/belt is prolonged greatly and buried field irrigation is truly made possible. The drip irrigation water seeps out from the top of the drip irrigation tube/belt and can gather to crop roots effectively, so that precious irrigation water is prevented from seeping underground, irrigation efficiency is improved greatly and operational energy consumption of drip irrigation systems is lowered.

Description

technical field [0001] The invention relates to a film-coated drip irrigation pipe / belt and a production method, in particular to a buried drip irrigation pipe / belt suitable for field crop application, and belongs to the technical field of water-saving irrigation 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 outside the drip irrigation pipe / belt, and the ...
