Multi-variate anti-blocking dropping head

Abstract

The invention relates to a multi-variable anti-clogging dripping emitter, the output flow rate can be regulated, anti-clogging, easy to install and disassemble and easy maintenance, water conveyance on the surface, deep irrigation and efficient water-saving irrigation, and further improving the utilization of irrigation water in the arid areas, relieving the conflict of the shortage of irrigation water. The invention comprises an dripping emitter connected with the conduit pipe, the emitter comprises an emitter cap, the emitter cap comprises an upper emitter cap of detachably connected and a lower emitter cap, the cavity of the emitter cap is intercalated a variable filter pipe, the both ends of variable filter pipe are respectively inserted into the upper and lower tapers of the emitter cap cavity, the emitter cap is connected with the underground water pipe, the lower end of the emitter cap is provided with a connection nozzle, the emitter cap is connected with the underground water pipe through the connection nozzle, a variable valve is arranged on the wall of the water outlet hole of the connection nozzle, the pipe wall of the underground water pipe is provided with a variable emitter, the variable filter pipe and the pipe hole of the variable emitter are lined with the sponge-like material.

Description

1. Technical field: [0001] The invention relates to a water-saving irrigation device, in particular to a multi-variable anti-clogging dripper. 2. Background technology: [0002] In the background technology, with the rapid development of modern industry and the continuous expansion of efficient agricultural irrigation area, the water consumption of both is increasing day by day. At the same time, the discharge of wastewater from industrial production causes the pollution of water resources. , leading to an increasingly serious crisis of water resources available for drinking water for humans and livestock and for agricultural irrigation, especially in arid areas, where the shortage of available water resources for agricultural irrigation is more prominent. Water-saving irrigation through facilities and pipelines is one of the important ways to effectively alleviate and improve the efficient use of water resources in arid areas. In arid and semi-arid areas, in order to save ...

AI Technical Summary

Problems solved by technology

[0004] 1. It is difficult to adjust the water flow of a single dripper according to irrigation needs and terrain changes in the current drip irrigation and infiltration irrigation pipelines, which are key components of water dispersion. In the case of mountainous and terrain changes, the dripper output Unadjustable water volume affects irrigation uniformity

[0005] 2. The irrigation water pipeline placed on the surface cannot be directly transported to the plant root distribution layer. At the same time, the surface drip irrigation soil water evaporates greatly, and the irrigation water is still not fully utilized by the plants.

[0006] 3. In seepage irrigation, the pipes are buried in the ground, although there is no evaporation of irrigation water, but it is difficult to dig canals to bury the pipes, and the installation cost is high. The drippers are buried in the soil, and the root system tends to grow and extend the drip holes, which is likely to cause biological blockage of the drip holes, difficult operation and maintenance. High operating and maintenance costs
