Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The technical key of the present invention is that the non-woven fabric or the open foam layer 2 provided with the water-blocking film layer 5 on the surface is originally created as the main material of the drip irrigation pipe or the drip irrigation belt. With the help of capillary action of non-woven fibers or open foam layer, the irrigation water seeps out from the drip irrigation pipe / passing water channel to the side seam. Intermittent bonding points 4 are set on the seepage edge seam 3, and the gaps between the bonding points on the edge seam form a water seepage channel, see figure 2 6 is indicated in the middle. The amount of dripping water per unit length of drip irrigation or infiltration irrigation can be controlled by the spacing of the bonding points. If the spacing is large, the amount of dripping water per uni...

Abstract

The invention provides an edge gap water seepage drip irrigation pipe / belt with a simple structure and low manufacturing cost for solving the problem that a buried facility blocks a water outlet. The drip irrigation pipe / belt main body is provided with non-woven fiber layers or open foaming layers of which single side is provided with a water blocking film layer; the drip irrigation pipe / belt is provided with a water through passage and 1 to 2 water seepage edge gaps; each water seepage edge gap is provided with interrupted bonding points; the non-woven fiber layers or the open foaming layers are oppositely bonded; and the clearance of the bonding points on the edge gaps forms a water seepage channel. The water dropping quantity of the unit length of the drip irrigation pipe / belt can be controlled through the distance between the bonding points, and the distance and the shape of the bonding points and the diameter of the water through passage can be changed at any time according to the use requirement. Compared with conventional drip irrigation pipe / belt production equipment, the production equipment for the drip irrigation pipe / belt has the advantages of simplicity, low investment and capability of greatly reducing the production cost.

Description

technical field [0001] The invention relates to a drip irrigation pipe or a drip irrigation belt, in particular to a side seam seepage buried drip irrigation pipe / belt suitable for field crops, 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 other is...
