COMBINED IRRIGATION SYSTEM Russian patent published in 2014 - IPC A01G25/02 A01G29/00 

FIELD: agriculture.

SUBSTANCE: combined irrigation system comprises the hydraulically connected water source, pumping station, filter, pressure gauges, stop valves, water-air retention tank, module of electroactivation of the irrigation water, main pipeline, network of distribution and irrigation pipes. On the irrigation pipes there are modules-micro-irrigators of the combined irrigation system, comprising covering irrigation pipe of the ring having threaded ends in the upper and lower pipes. The lower threaded pipe is fixed to the injector for drip irrigation of root soil layer, consisting of thrust water-carrying washer, a diaphragm, a spring-loaded conical valve, a bearing washer with the calibration orifice, a hollow cone with the water discharge openings formed on the left-hand orientation helix. In the upper threaded pipe a cylindrical water supply barrel is mounted, a thrust water-carrying washer, a diaphragm with a conical valve fixed by the tension spring between the thrust washer with the calibration orifice and the thrust washer with the water-carrying opening. The conical spring-loaded valve in its upper part has petal guides. All elements are located in a cylindrical water supply barrel having in the inner surface the helical guide of left hand orientation. In the upper part of the water supply barrel the flow guide is made in the form of a surface of rotation of the fourth order coupled with the water discharge openings directed tangentially to the inner surface of the water supply barrel counter clockwise. Over the upper part of the water supply barrel the spherical deflector shell is mounted, which lower edge is located below the axis of the water discharge openings.

EFFECT: acceleration of plant growth and development, increase in productivity and quality of the products obtained.
