Anti-clogging joint used for soil improvement by drip irrigation under film in saline-alkali land

Abstract

The invention discloses an anti-clogging joint used for soil improvement by drip irrigation under a film in a saline-alkali land, belonging to the technical field of drip irrigation. The anti-clogging joint comprises a water inlet pipe, wherein the outer wall of the left end of the water inlet pipe is provided with an installation thread; the right end of the water inlet pipe is connected with an anti-clogging pipe; the bottom part of the anti-clogging pipe is provided with a silt outlet; the bottom part of the silt outlet is provided with a silt collecting tank; and the bottom part of the inner cavity of the silt collecting tank is provided with a pressure control valve. The anti-clogging joint provided by the invention has the advantages of convenient use, ingenious design, and strong practicability and novelty; by utilizing the silt collecting tank arranged at the bottom part of the anti-clogging pipe, silt in a pipeline can be effectively collected; the pressure control valve can automatically discharge impurities like the silt; an anti-clogging device can effectively filter impurities like the silt; an anti-clogging blade can scrape congelation located at the left side of a filtration device; and the anti-clogging joint can effectively prevent the impurities like the silt from entering the drip-irrigation pipe and clogging the drip-irrigation holes, so the survival rate of a plant is improved, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to an anti-blocking joint for soil improvement of drip irrigation under saline-alkali mulch. Background technique [0002] As we all know, soil improvement in saline-alkali land is difficult, mainly reflected in the high salt content of soil components in saline-alkali land, serious soil compaction, which is not conducive to plant production, and serious soil desertification, which makes it difficult to improve saline-alkali land. [0003] With the continuous innovation of science and technology, some irrigation technologies have emerged as the country vigorously supports the improvement of saline-alkali land. Under-mulch drip irrigation is a way of integrating water-saving irrigation, drip irrigation, etc., that is, on the drip irrigation belt or drip irrigation capillary. Cover with a layer of mulch. This technology is to supply water through a controllable pipeline system. Af...
