Cylindrical micro-porous labyrinth drip irrigation tape as well as machining method and equipment

Abstract

The invention provides a cylindrical micro-porous labyrinth drip irrigation tape as well as a machining method and equipment. The drip irrigation tape consists of a drip irrigation tape water delivery channel and a labyrinth channel, wherein a micro-porous labyrinth channel consisting of filling cotton ropes is formed in the water delivery channel side surface of the drip irrigation tape, inner water outlets are radially and evenly arranged in the micro-porous labyrinth channel and adjacent to the water delivery channel, and outer water outlets staggered with the inner water outlets extend to edges of the drip irrigation tape. The machining method comprises the steps as follows: two cotton ropes penetrate through an extrusion die head to be used as cylindrical labyrinth filler while the drip irrigation tape water delivery channel is extruded, the cotton ropes are sleeved with an extruded thin-walled cylinder, inner and outer 8 shapes are extruded, the 8 shape on the outer side forms the drip irrigation tape water delivery channel, and the small 8 shape on the inner side wraps the two cotton ropes in a plastic film respectively to form a cylindrical micro-porous labyrinth. By means of the drip irrigation tape as well as the machining method and equipment, the anti-blocking performance can be improved substantially, filter equipment of a drip irrigation system can be simplified, and the running energy consumption of the drip irrigation system can be reduced. When the irrigation specification of the drip irrigation tape is required to be changed, all that is required is to select the cotton ropes with proper diameters or the number of the water outlets instead of changing production line hardware.

Description

technical field [0001] The invention relates to a processing method and equipment for a cylindrical microporous labyrinth drip irrigation belt, in particular to a production method and equipment for a drip irrigation belt suitable for underground application of field crops, 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 ...
