(57) Abstract:Usage: in land reclamation, namely automatic atomized irrigation irrigated lands. The invention is: to stabilize radius watering when changing the pressure of the supplied water sprinkling device is made in the form of water inlet riser 1 with a rotating hollow operational body 2, which water flows through the nozzle 3 connected to its cavity elastic elements in the form of a spring-loaded hose, bellows, etc., 4. The nozzles are angled to the axis of rotation of the working body and to increase the irrigation area are supported in the plane of rotation of the disk 5. 2 C.p. f-crystals, 1 Il. The invention relates to the reclamation and can be used for automatic irrigation erosion-prone slopes.The purpose of the invention automatic stability radius irrigation regardless of the water pressure in the supply line.The task is the fact that the spray water nozzle attached to the housing of the working body by means of elastic elements.The drawing shows the riser 1 at a feed water pipe attached to the end of the hollow disk 2, placed tangentially to the PLA with the cavity of the disk. The nozzle 3 can be supported in the plane of rotation, for example, resting on the flange 5 of the hollow disk 2.Works sprinkling apparatus as follows.When water in the riser 1 and the end of the disk 2 through the nozzle 3, directed in opposite directions, there is reactive power and disk 2 starts to rotate. When the rotation of the centrifugal forces that deflect the nozzle 3 in the radial direction, deforming the elastic elements 4. From changing the angle of water discharge is reduced tangential component of thrust and the speed starts to drop.You can increase the radius of irrigation, if we exclude the sagging downward nozzles on the elastic elements, for example, by installing additional supports disk.Elastic elements 4 are structurally can be done in different ways, for example, in the form of a segment of rubber hose coiled outside cylindrical spring, or in the form of bellows and other 1. Sprinkling apparatus, comprising a water inlet riser and the working body in the form of a hollow rotating disk arranged at an angle to the axis of rotation of the nozzles, wherein the nozzles are connected with the working body through podbrdo or an extra disc of larger diameter, located beneath it and prevents sagging elastic elements with nozzles.3. The apparatus according to p. 1, wherein each elastic element is designed as a bellows or cut hose.
FIELD: agricultural engineering, in particular, equipment for drop irrigation of farm crops.
SUBSTANCE: apparatus has cylindrical casing with inlet and outlet openings. Cylindrical casing has threaded covers and body. Valve and elastic cuff are movably positioned inside cavity of cylindrical casing. Apparatus is further equipped with additional cuff. Main and additional cuffs are provided with orifices. Valve is made in the form of concavo-concave lens arranged in spherical belt. Valve is manufactured from material having density smaller than density of water, in particular, valve may be made from cork of 0.2-0.3 t/m3 density. Valve is arranged in casing between cuffs and is adapted for alternating contacting through cuffs with projections oppositely arranged inside casing cavity. Projections are made in the form of spherical segments, with radius of spheres of segments being smaller than radius of spheres of concavo-concave valve lens. Difference between radii of projection sphere and that of spheres of concavo-concave valve lens is equal to thickness of elastic cuffs. Channels on apexes of cover and casing projections are extending in radial direction toward inlet and outlet openings.
EFFECT: increased efficiency and enhanced reliability in operation.
