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 the central hole being reduced 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.

A sprinkler deflector nozzle is also known, comprising a housing mounted on a rack, connecting the pillar to a support with a deflector mounted on it and housed with a rotatable 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 fluid flow regulator 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 a in the latter with the possibility of axial movement by the core (SU, copyright certificate No. 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 by us 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 providing 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 finely dispersed sprinkler nozzle, which includes a cylindrical body mounted on a water supply pipe with water outlets, a conical flow divider and a screw guide fixed on its outer surface are installed, the outer diameter of which is equal to the inner diameter of the cylindrical housing, the lower part of the conical divider mates with the lower edge of the water outlets, is made screw in the housing tangentially to the inner diameter of the housing and directed counterclockwise, screw flow guides are installed in the inner cavity of the water outlets with counter-clockwise winding of the coils, the conical flow divider is fixed in the internal cavity of the housing by means of a thread, while the generators of the conical divider are mated with the lower edge of the water outlets along a radius equal to the diameter of the water outlets, while the number of entries of the helical guide of the conical divider I am equal to the number of water outlets, the number and diameter of water outlets are selected from the condition of supplying a given flow rate of the sprinkler nozzle.

The analysis of the prior art by the Applicant, 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 did not find 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 presents a fine sprinkler nozzle, a diametrical section. (Conventionally shown one turn of a screw guide).

Figure 2 is a section aa of the housing of figure 1.

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

The fine sprinkler nozzle consists of a cylindrical body 1 with a threaded tip 2, in the inner cavity of which a conical flow divider 3 is installed and a screw guide 4 is mounted on its outer surface. The outer diameter of the screw guide 4 is equal to the inner diameter of the cylindrical body 1. The lower part of the conical divider 3 is mated with water outlets 5 made in the housing 1 tangentially to the inner diameter of the housing and directed counterclockwise. In the internal cavity of the water outlets 5, screw flow guides 6 are installed with counterclockwise winding of the turns of the screws. The number of visits of the turns of the auger of the conical divider is equal to the number of water outlets. The conical divider 3 is fixed in the inner cavity of the housing 1 by means of a thread 7, while the generatrices of the conical divider 3 are mated to the lower edge of the water outlets 5 in a radius equal to the diameter of the water outlets 5. The number of entries of the screw guide of the conical divider 3 is equal to the number of water outlets 5. Number and the diameter of the water outlet is selected from the condition of supplying a given flow rate of the sprinkler nozzle.

Fine sprinkler nozzle works as follows. When water is supplied from the water supply pipe into the cylindrical body 1, the flow is compressed by a conical divider 3, and its speed increases. When this flow interacts with the turns of the screw guide 4 and acquires a rotational movement counterclockwise, which increases the energy of the moving stream. In the lower part of the conical divider 3, the rotating stream enters the water outlet 5 and interacts with the screw guides 6 of the flows, which further increases the energy of the water particles of the streams ejected from the water outlet 5. When meeting with the atmosphere, the rotating stream breaks into fine droplets and enters the leaf-stem part of the plants and the soil, providing hydration with water, which has increased energy and vitality.
