Externally-embedded gap annular plastic turbulence douche for drop irrigation

Abstract

The invention relates to an externally-embedded gap annular plastic turbulence douche for drop irrigation. Because the douche is embedded in the lower layer of earth surface, the douche can automatically control to evenly drop, the water dropper has small possibility of clogging and aging, the service life of the douche can be 25 years, and the douche can be continuously and reliably operated under the extremely severe conditions. The douche is suitable for various perennial deep-root crops, such as fruit-bearing forests, ecological forests, traffic protection forests, fixing forests, farmland breakwind, desert economic vegetations and the like. The appearance of the douche is characterized in that a black plastic douche water jacket formed by one-time injection and a water cover are sheathed into a totally-closed douche; then the totally-closed douche is spliced with PE seam capillaries of phi 4, 6 and 8 to form a whole turbulence douche having no possibility of clogging; the turbulence douche is externally embedded on a PE (poly ethylene) hose of phi16 according to the space between planted crops; the turbulence douche and the PE hose are embedded on the root positions of plants on the lower layer of the earth surface; and thus, the whole installing project of the whole drop irrigation system can be finished.

Description

1. Technical field [0001] The present invention relates to a water irrigation device that seeps around plant roots in the subsurface. The biggest advantage is high uniformity of water irrigation, no fear of blockage, water saving, fertilizer saving, energy saving, environmental protection and sanitation, and continuous and reliable operation under extremely harsh conditions. It is suitable for perennial deep-rooted crops such as various fruit forests, ecological forests, traffic protection forests, windbreak and sand-fixing forests, farmland windbreak forests, and desert economic vegetation. 2. Background technology [0002] As we all know, drip irrigation is one of the best and fastest-growing water-saving irrigation technologies in the world at present. However, clogged drippers and poor drip uniformity are prone to aging, which is still a worldwide technical problem that affects the promotion of drip irrigation and water-saving technologies. The present invention is exact...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of poor uniformity of irrigation water, easy blockage of drippers, easy aging and low utilization rate of automatic equipment adaptation performance in the existing drip irrigation technology, the present invention provides a kind of "outer-mounted gap ring plastic turbulent flow for drip irrigation". Irrigator", the irrigator is buried in the subsurface, which not only controls the dripping water evenly, but also the dripper is not easy to block and age, and the service life can be as long as 25 years, ensuring continuous and reliable operation under extremely harsh conditions
