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.

A sprinkler deflector nozzle is also known, comprising a housing mounted on a rack, connecting a support to a rack 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 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 stiffening ribs on the compartments and undercutting the curved surface of the bowl between its peripheral annular edge and convexity, each of the compartments has height p A variable cross-section, provided with the possibility of stepless movement, the deflector and nozzle are connected by means of a rack (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 fine sprinkling with water having increased energy and vitality, increased yield.

The specified technical result is achieved by the fact that in the known vortex sprinkler nozzle-activator containing a housing with water outlet mounted by means of a nipple of a water supply pipe, a water activator is installed in the inner cavity of the housing, which is a circular cone, on the side surface of which a screw with left-side multi-start winding is fixed, the outer diameter of the screw is equal to the inner diameter of the housing, the base of the cone is associated with water outlets made in the body all along the radius, 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 vortex sprinkler nozzle-activator, the number of visits of the screw winding is equal to the number of water outlets, in conjunction with the water outlets on the outer surface of the casing the holes are fixed deflector blades made in a helical line with a left-handed orientation.

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 shows the vortex sprinkler nozzle-activator, a diametrical section (conventionally shown two runs 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 vortex sprinkler nozzle-activator contains a cylindrical body 1 mounted to the water supply pipe using a thread 2. In the inner cavity of the body there is a water activator consisting of a circular cone 3, on the side surface of which a screw 4 with left-side multi-winding is fixed, the outer diameter of the screw 4 is the inner diameter of the housing 1. The base of the cone 3 is associated with the lower edge of the water outlets 5, made in the housing 1 along the radius. The water outlets 5 are directed counterclockwise tangentially to the inner diameter of the housing 1. The number and diameter of the water outlets 5 is determined depending on the required flow rate of the vortex sprinkler nozzle-activator. The number of entries of the screw winding 4 is equal to the number of water outlets 5. On the outer surface of the housing 1, deflector blades 6, made along a helical line with a left-handed direction, are fixed in conjunction with the water outlets 5.

The water activator is fixed in the inner cavity of the housing 1 using thread 7.

The vortex sprinkler nozzle activator operates as follows. When water is supplied to the internal cavity of the housing 1, the flow enters the auger 4 and acquires a counterclockwise rotation. It has been established by experimental studies that when the flow rotates counterclockwise, the structure of water changes and it becomes structured, and its energy and vitality increases. At the same time, as the cone 3 flows around it, its living cross section decreases, and the flow velocity increases. Compression of a rotating stream provides a significant increase in the energy and vitality of water. A rotating stream with increased energy and vitality is ejected through the outlet 5 to the deflector blades 6 counterclockwise, which additionally provides an increase in the energy and vitality of the water. When flowing around the blades 6, trickles of water coming from the water outlets 5 receive an additional rotational movement counterclockwise and an additional increment of energy and vitality. When leaving the blades 6, the rotating streams are destroyed into tiny drops and enter the leaf-stem part of the plants and irrigated soil.

The energy and vitality of water acquired in the vortex sprinkler nozzle activator is transmitted to plants, which significantly increases the yield of crops.

The simplicity of the developed design and the possibility of simplified maintenance increases the reliability of the vortex sprinkler nozzle-activator.
