Node type filtration irrigation pipe perforating mechanism

Abstract

The node type filtration irrigation pipe perforating mechanism includes power driven running roller, paired wheel and fixing stage, and features the umbrella-shaped perforating assembly fixed onto the running roller and with perforating cone. While the running roller and the paired wheel rotate, the filtration irrigation pipe is made to move linearly by means of the friction force of the rotating running roller and paired wheel, and the umbrella-shaped perforating assembly perforates the filtration irrigation pipe. The holes on the filtration irrigation pipe have great inside part and small outside part and the filtration irrigation pipe has monoway water outflow characteristic. The present invention has simple perforating structure, low cost, simple perforating process and other advantages.

Description

technical field [0001] The invention belongs to a punching machine, in particular to a node type seepage irrigation pipe punching mechanism. Background technique [0002] Seepage irrigation is one of the most advanced water-saving irrigation technologies for facility gardening in the world after drip irrigation. Whether this high-tech can be transformed into productivity as soon as possible depends on the price of the product and the operability of the technology. The two are comprehensively reflected by farmers. degree of acceptance. [0003] At present, there are roughly the following types of seepage irrigation pipes at home and abroad: ①Represented by Italy, plastic pipes with an inner diameter of 10mm to 20mm and 5mm to 10mm longitudinal seams on the pipe wall are used as seepage irrigation pipes. The principle of plastic pipe has good elasticity. When the water is supplied, the longitudinal seam of the pipe wall is opened to seep water outward, and the longitudinal se...

AI Technical Summary

Problems solved by technology

[0004] There are three difficulties and problems in the large-scale promotion of the above-mentioned types of irrigation pipes: first, the production process of the irrigation pipes is complicated, and the microcellular foaming injection molding process can be divided into four basic stages: the fat melting stage- - Supercritical gas injection, mixing and diffusion stage - Injection stage - Foaming stage

The second is that the price is expensive. The annual production of 10 million meters of foam pipes with such a process requires an investment of 4 million yuan in equipment and working capital, resulting in high product prices; the third is to use a needle to punch holes on the pipe wall, often with different apertures. etc. Poor accuracy and low irrigation uniformity
