Description
Technical field
The present invention relates to agricultural irrigation technology, be specifically related to a kind of adjustable-pressure sub-irrigation system.
Background technology
Advanced agricultural water-saving irrigation technology has sprinkling irrigation, slight irrigation etc. at present.The use of sprinkling irrigation is subject to the impact of meteorological condition, in the larger northern China arid and semi-arid area of wind-force, evaporation of water and drift loss in the sprinkling irrigation process so that the sprinkling irrigation water-saving result have a greatly reduced quality, sprinkling irrigation needs larger pressure in addition, for having relatively high expectations of the energy, be difficult to carry out in some area.Irrigation system utilizes Special Equipment, pressure water stream is become tiny current or water droplet, near the wetting crop root layer soil, has desirable water-saving result, this system generally comprises the parts such as head pivot, delivery main, arm, hollow billet and water dropper, the equipment investment price is high, generally is applied to the higher crop of economic worth, and the land for growing field crops of general crop is used and is difficult to implement.At present, it no matter is sprinkling irrigation or slight irrigation all is to be the irrigation of positive head at pressure of supply water, irrigate the rear section soil body and can reach the water saturation state, be consumed in subsequently soil evaporation and crop transpiration water consumption, cause soil experience alternation of wetting and drying, and the undue fluctuation meeting of soil moisture content makes plant coerced by drought and waterlogging, increases the generation of damage by disease and insect, causes the waste of fertilizer and to the problems such as pollution of environment.Present existing Negative pressure irrigation system has " a kind of negative pressure automatic irrigation system (application number 201110136158.8) ", utilize its technology can realize Negative pressure irrigation, but the generation of its negative pressure relies on the discrepancy in elevation for the water surface and irrigator to realize, although can regulate negative pressure, but underaction, because the enforcement of this Negative pressure irrigation requires must be lower than irrigator for the water surface, therefore is difficult to carry out for field crop.Granted patent " a kind of negative pressure water head irrigation system (patent No. ZL200510123974.X) " can only be carried out Negative pressure irrigation, can not realize with no pressure and have to press irrigating, and the pressure of this patent is regulated dumb convenience in addition, has limited the scope of its use.Granted patent " a kind of nothing is distinguished local controlled-water subirrigation system (patent No. ZL 03108051.0) at all " does not possess pressure controlled function, can only carry out with no pressure and irrigate, and can not realize negative pressure and have to press irrigating.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of adjustable-pressure sub-irrigation system is provided, solve mainly that existing prior art investment is large, energy dissipation is large, water use efficiency is not high, negative pressure is regulated the problems such as difficulty.
Technical scheme of the present invention is: a kind of adjustable-pressure sub-irrigation system, and its special character is that it is comprised of stilling chamber, water supply chamber, water delivery hollow billet and irrigator; Described irrigator is embedded in underground and is connected with the water delivery hollow billet, and the water delivery hollow billet links to each other with water supply chamber by the delivery port with gauge tap; The sealing of described water supply chamber lower end, the second air inlet pipe moving up and down is inserted into its inside by the water supply chamber upper end, and air exhaust nozzle and water inlet are established in the water supply chamber upper end, and water inlet is sealed by the second sealing-plug; The sealing of described stilling chamber lower end, there is a filler upper end, and the filler is sealed by the first sealing-plug, and the first air inlet pipe moving up and down is inserted into its inside by the stilling chamber upper end, and there is an outlet nozzle stilling chamber upper end; Described outlet nozzle and air inlet pipe are connected by connecting hose.
Further, the distance of the water surface is h in described the first air inlet pipe end-to-end distance tripping power conditioning chamber
