SUBSTANCE: invention concerns irrigation method by fine dispersed and drop sprinkling, and can be applied in mobile aggregates for sprinkling with drop size suitable for irrigation of a wide range of cultivated plants with irrigation water of enhanced biological activity and vitality. Water promoter in the form of cone with left-hand worm multithread spiral winding is mounted in the internal space of case of sprinkling promoter nozzle. Worm diametre is equal to internal case diametre. Cone base interfaces with water release orifices in the case. Cone generating lines interface with water release orifices by radius. Water release orifices are directed counter-clockwise along a tangent to the internal case diametre. Number and diametre of water release orifices is determined by specified flow rate of the sprinkling nozzle. Number of left-hand worm winding spiral turns in conical splitter is equal to the number of water release orifices. Deflector blades made along the radius circle arc are mounted on external case surface and interface with water release orifices.

Description

The invention relates to techniques for irrigation with fine and drip irrigation and can be used in mobile installations for producing rain with droplet sizes acceptable for irrigation of a wide range of cultivated crops with increased energy and vitality of water.

Known nozzles of the sprinkler apparatus, comprising a housing, a deflector fixed to the rack and a nozzle with a central hole, in which, in order to enable the regulation of rain intensity during irrigation, the nozzle is made of a shape memory material with a reduction of the central hole from a larger diameter to a smaller one when heated moreover, the rack is made of the same material as the nozzle, with a mass equal to the mass of the nozzle; it is equipped with a power source and adjustable resistance, while the stand and nozzle are electrically connected to each other and connected to the power source through adjustable resistance (SU, copyright certificate No. 1616711).

The disadvantages of the described nozzle include a small range of changes in the size of the raindrops and the complexity of the design. To change the position of the deflector post, an entire electrical network with communications and a power source is required.

Also known is a sprinkler deflector nozzle containing a housing mounted on a rack, connecting the pillar to a support with a deflector mounted on it and placed in the housing with the possibility of rotation of the fluid flow regulator, in which, with the aim of increasing the reliability of the nozzle, the quality of the spray and expanding technological capabilities, the flow regulator the liquid is made in the form of a cylindrical liner with diametrically located channels of different diameters, and the deflector is made with a central channel and is equipped with in the latter axially movable core (SU, Inventor's Certificate №923635).

During operation of the described nozzle, first of all, small-diameter radial channels are clogged. Each nozzle also requires careful individual adjustment when supplying irrigation water under operating pressure. To clean the radial channels, complete disassembly of the nozzle is required. All this reduces the technological reliability of the sprinkler. In addition, the nozzle does not provide increased energy and vitality of water.

A nozzle for a sprinkler assembly is known, comprising a housing mounted by means of a nipple of a water supply pipe, a deflector fixed to the rack and a nozzle with a central hole, the deflector being made in the form of a concave bowl facing the nozzle with a bulge in its middle part and a threaded hole combined with the axis of symmetry, divided stiffeners on compartments and undercut of the curved surface of the bowl between its peripheral annular edge and convexity, each of the compartments has A variable cross-section, provided with the possibility of stepless movement of the deflector and the nozzle are connected by means of a strut (RU, patent No. 2173584).

The disadvantages of the described nozzle sprinkler unit include design complexity, low reliability, lack of ability to obtain fine sprinkling, increasing energy and vitality of water.

This design is accepted as the closest analogue.

The essence of the claimed invention is as follows.

The problem to which the invention is directed is the creation of a universal nozzle for sprinkler machines that provides specified water flow rates, fine sprinkling, the ability to conduct simplified maintenance, increase energy and vitality of water.

EFFECT: increased reliability of operation, simplified design, obtaining finely dispersed sprinkling with water, which has increased energy and vitality.

The specified technical result is achieved by the fact that in the known sprinkler nozzle-activator comprising a housing mounted by means of a nipple of a water supply pipe, a water activator is installed in its inner cavity, which is a cone with a screw on the left-hand side of multi-helical winding, while the diameter of the screw is equal to the inner diameter of the housing, the base the cone is associated with water outlets made in the housing, the pair of generatrices of the cone with water outlets is made along p the diameter, the water outlets are directed counterclockwise tangentially to the inner diameter of the casing, the number and diameter of the water outlets is selected depending on the required flow rate of the sprinkler nozzle-activator, the number of visits of a screw left-hand screw winding is equal to the number of water outlets, on the outer surface of the casing it is conjugated with water outlets fixed deflector blades made in an arc of a circle.

The analysis of the prior art, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allowed to establish that the applicant has not found an analogue characterized by features identical to all the essential features of the claimed invention.

Therefore, the claimed invention meets the criterion of "Novelty" under existing law.

The invention is illustrated by drawings.

Figure 1 shows a diametrical section of the sprinkler nozzle-activator (conventionally shown one run of screw winding).

Figure 2 is a section aa in figure 1.

Information confirming the possibility of implementing the claimed technical solution is as follows.

The sprinkler nozzle-activator contains a cylindrical body 1 with a threaded connecting tip 2, in the inner cavity of which a water activator is installed, which is a cone 3 with a screw left-side multi-thread screw winding 4, while the diameter of the screw is equal to the inner diameter of the housing. In the lower part of the housing 1 there are water outlets 5 directed counterclockwise tangentially to the inner diameter of the housing 1. The number and diameter of the water outlets are selected from the condition of supplying a given flow rate through the sprinkler nozzle-activator. The generatrices of the cone 3 at the base are mated with the lower edge of the water outlets 5 in radius. The number of entries of the screw left-hand screw winding is equal to the number of water outlets 5. On the outer surface of the housing 1, deflector blades 6, made along an arc of a circle, are fixed in conjunction with the water outlets 5.

Sprinkler nozzle activator works as follows. When water is supplied to the housing 1, the flow meets the screw multi-start screw winding 4 and acquires a counterclockwise rotational movement. Experimental studies have established that in a counterclockwise flow of water, its structure changes, and the energy and vitality of water increases. When the cone 3 flows around it, its living cross section decreases, and the flow velocity increases, and during rotation, the energy and vitality of water increases. A rotating stream with increased energy and vitality is ejected through the outlet 5, while its rotational movement increases, which further increases the energy and vitality of the water.

The water coming from the water outlet 5 with a high-pressure head, when interacting with deflector blades, is divided into tiny particles, enters the leafy mass of plants and soil, while the energy and vitality of plants and, accordingly, productivity are increased.

The simplicity of the design provides increased reliability of the sprinkler nozzle-activator and obtaining fine sprinkling with water that has increased energy and vitality.
