Anti-blocking buckle of infiltrating irrigation pipe

Abstract

The invention provides an anti-blocking buckle for a seepage irrigation pipe, which solves the problem that sediment and capillary heels are easily blocked in the prior art. The present invention includes two symmetrical arched pieces, which form a tubular member wrapping the irrigation pipe after the two arched pieces are butted. The inner wall of the arched piece is provided with a flow groove for water to flow through, and the edge of the arched piece is provided with a water outlet channel, the flow channel is connected with the water outlet channel, the orthographic projection of the water outlet on the seepage irrigation pipe on the anti-blocking buckle is located in the flow channel, and an anti-blocking flexible film is fixed on the flow channel, and the anti-blocking flexible film is connected to the anti-blocking flexible film on the seepage irrigation pipe. The position of the water outlet corresponds, and the area of ​​the anti-blocking flexible membrane is larger than the area of ​​the water outlet on the infiltration irrigation pipe; under normal pressure, the anti-blocking flexible membrane does not contact the bottom of the flow tank and the water outlet. The design of the anti-blocking flexible membrane can block the flow during infiltration and irrigation, and can also prevent the negative pressure generated in the infiltration and irrigation pipe when the water is cut off, and the sediment and capillary roots outside the anti-blocking button will be sucked into the anti-blocking button to cause silting.

Description

technical field [0001] The invention belongs to the field of agricultural irrigation and water delivery, in particular to an anti-blocking buckle for seepage irrigation pipes. Background technique [0002] Infiltration irrigation is an underground water-saving irrigation method. Different from other irrigation methods, it is transferred from the surface to the ground for irrigation, and some people call it subsurface drip irrigation. It irrigates by burying a unique plastic pipe underground. This plastic pipe is called a seepage pipe. According to the needs of the farmers, small holes are made at intervals on the seepage pipe. When the pipe is filled with water, The small hole will gradually ooze out from the small hole like sweating. Through this structure, water and fertilizer can be sent directly to the underground root zone of the crop, and the plant only needs to absorb it directly. The advantage of infiltration irrigation is that it reduces the evaporation of water o...

AI Technical Summary

Problems solved by technology

[0004] Due to the existence of capillary roots and fine soil underground, the seepage holes of the flow channel grooves of the above-mentioned short-seepage pipes will still enter the capillary roots and soil under the action of negative pressure, and further enter the holes in the wall of the water delivery pipe. Over time, there will still be The problem of blockage, therefore, the above structure only delays the time of blockage, and does not fundamentally solve the problem of blockage
