(57) Abstract:Usage: in reclamation techniques, particularly in sprinkling devices for irrigation atomized by way of erosion on the dangerous slopes of varying steepness. The inventive sprinkler device is made in the form of a hollow disk 1 with a cover 2, provided with 3 pairs of nozzles 3 of different diameters, aimed at a tangent. Site rotation is represented by a sleeve 4 made in one piece with the disk 1, put on the tube - riser 5 is fastened to it by means of a washer 6 and pin 7. 2 Il. The alleged invention relates to techniques for reclamation and can be used for irrigation erosion-dangerous slopes of varying steepness.A device for spraying liquid, consisting of a body with a hole, which is closed by a conical valve. The contact force of the valve to the seat is adjustable and spring-loaded screw. Fluid from the valve leaves a thin film, disintegrating in the form of rain drops on a circle (see and.with. USSR N 138 2497, CL 05 1/32).The disadvantage of this design is the formation of large drops and uneven watering in a circle.Known sprinkling apparatus according to as.with. CCC fixed reflector at a certain angle. At the end of the console has a nozzle with 4 holes for ejection of jets of water at different angles.When leakage of liquid from these holes are part of the jets striking the reflector causes the console to rotate, irrigation nearby radius; other jet impinges on the reflector at other points, impact and water, respectively, with increasing radius, thus provide uniform watering in a circle.The disadvantage of this design is its complexity, large size, metal, large size of raindrops, which is unacceptable for irrigation of slopes.The purpose of the invention more atomized water distribution in a circle, simplifying the design, reducing its size and metal.This is achieved by the fact that in the sprinkler apparatus having a working body, the rotation unit and the pipe riser, work the body in the form of a hollow disk with a lid. In the case of the disk at an angle of 90oat the ends of each of the three intersecting angle 120odiameters posted by pairs of nozzles with a section on 3,140; 4,710 and 5,495 mm2(the number of pairs of nozzles can be increased), and the riser pipe has a cross section of at least 26,690 mm2. The drive cover and the jets vypolneno disk is carried out by the reaction of water jets, because each pair of nozzles is directed in the opposite direction relative to the direction of the second.In Fig. 1 is a side view, and Fig. 2 a top view of the sprinkler device.We offer sprinkler apparatus consists of a hollow disk 1 having three pairs of nozzles 3 different sections, screw in the disk 1 at an angle of 90o.The disk is provided with a cover 2. Site rotation is a sleeve 4, made in one piece with a hollow disc 1 worn on the riser pipe 5 and fastened to it by means of a washer 6 and pin 7.Sprinkler apparatus works in the following way:
the pipe-shaft 5 inside the disk 1 under the pressure of water; the reaction of the jets causes the rotating disk 1 sprinkler apparatus, with increasing pressure of a growing range of water, at the same time increases the speed of rotation of the disk 1, contributing to a better dispersion of water; the presence of different diameters of the nozzles 3 allows you to have different kinetic energy of the emitted jets, making changing the length of the flight of jets and watering uniformity is achieved in a circle.The main parts of the device can be made of plastics. This allows to drastically reduce the consumption of metal for fabrication.Design in General is greatly facilitated, and the use of plastics lengthen the turnaround time of service.An additional effect is the saving of irrigation water is almost 2 times due to the fine spray of water, improve the micro-climate, prevent soil erosion and opportunities to serve with irrigation water soluble forms of mineral fertilizers for growing foodstuffs, which is very important for the conditions of the slopes, as well as opportunities to contribute chemicals to control pests, weeds and plant diseases. Sprinkling apparatus comprising a disk with cover and intake pipe with nozzles placed around the circumference and is made at an angle to its surface, characterized in that the disk has at least three pairs of evenly placed nozzles, and the nozzles angled 90oto its surface and each pair has a different cross-section.
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.
