Ceramic root irrigation and microspray irrigation complemented irrigating device

Abstract

The invention discloses a ceramic root irrigation and microspray irrigation complemented irrigating device. The ceramic root irrigation and microspray irrigation complemented irrigating device comprises a tubular casing and a movable pipe, wherein the movable pipe is assembled in a slidingly sealing mode inside the casing, a gap is formed between the movable pipe and the casing, and the upper endof the movable pipe extends out of the casing and is provided with an atomizing nozzle; the side wall of the casing is connected with an irrigating unit through a by-pass pipe; the connected part between the irrigating unit and the by-pass pipe is provided with a first flow regulating valve, and the lower end of the movable pipe is provided with a second flow regulating valve; the opening degree of the first flow regulating valve and the second flow regulating valve is adjusted through water flow. Through a combined structure, the ceramic root irrigation and microspray irrigation complementedirrigating device combines spray irrigation and root irrigation within one irrigation device; by means of an internally arranged pressure compensating structure, a ceramic root irrigation and microspray irrigation combined manner can be applied to irrigation of different crops, so that the ceramic root irrigation and microspray irrigation complemented irrigating device can be high in utilization efficiency of irrigating water, simple in structure, good in hydraulic performance and high in channel blocking resistance.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation in arid areas, and in particular relates to an irrigation device complementary to ceramic root irrigation and micro-spray irrigation, which utilizes an upper atomizing nozzle for micro-spray irrigation, and uses ceramic tubes for root irrigation. Background technique [0002] With the development of modern water-saving irrigation for many years, people have gradually realized that above-ground irrigation (such as sprinkler irrigation and micro-irrigation) and underground irrigation technologies are the most water-saving technologies. However, the development of sprinkler irrigation has been seriously hindered by the disadvantages of high investment, strong wind influence, and high energy consumption in above-ground irrigation; while underground irrigation is easy to block, difficult to find and repair after blockage, and cannot moisten seeds at the sowing and seedling s...
