Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The technical key of the present invention is to create a labyrinth channel that uses non-woven fabric or open foam interlayer 2 instead of drip irrigation pipe or 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. Discontinuous bonding points 4 are set on the water seepage side seam 3, and the gaps between the bonding points on the side seam form a water seepage channel. 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 unit time and the same pressure will be large; if the spacing is small, the amount of dripping water per unit tim...

Abstract

The invention provides an edge seam sandwich layer water seepage drip irrigation pipe / belt with the advantages that the structure is simple and the manufacture cost is low. In the invention, non-woven fibers or open micro bubbles are used for replacing the traditional labyrinth flow passage, and the problem of underground water outlet blockage is solved. The edge seam sandwich layer water seepage drip irrigation pipe / belt is characterized in that a main body is provided with a water passing passage and one to two water seepage edge seams, wherein the water seepage edge seams are provided with non-woven fiber layers or open foaming sandwich layers, intermittent bonding points are arranged on the water seepage edge seams, and gaps of the bonding points on the edge seams form a water seepage passage. The water drip quantity of the drip irrigation pipe / belt in the unit length can be controlled through the spaces of the bonding points, and the spaces and the shapes of the bonding points and the diameter of the water passing passage can also be changed at any time according to use requirements. The production equipment is also simpler than the existing drip irrigation pipe / belt production equipment, the investment is low, and the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to a drip irrigation pipe or a drip irrigation belt, in particular to a side seam interlayer seepage drip irrigation pipe / belt suitable for the application of 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...
