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 design of the sprinkler-activator with adjustable rain quality, cross section. Figure 2 is a view A in figure 1.

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

The sprinkler-activator with adjustable rain quality contains a L-shaped body 1 mounted to the water supply pipe, having a conical extension 2 in the lower part. In the internal cavity of the body on the threaded rod 3, a rotation body of a single-cavity hyperboloid 4 is installed, covered by turns 5 of the screw. The outer edge of the turns 5 of the screw is made on a conical generatrix, i.e. inscribed in the internal cavity of the conical expansion 2. The turns of the 5 auger have a left-side orientation, and the auger itself is interchangeable depending on the required rain parameters, which should correspond to the pitch of the turns of the 5 auger and the number of entries.

In the lower part, a flow divider 6 is fixed to the body of revolution of the one-sheeted hyperboloid 4 - a sprinkler fixed to the body of rotation of the one-sheeted hyperboloid 4 using a pin 7. The stream divider 6 is made in the form of a disk washer with water-absorbing visors 8 on its bottom. Between the conical extension 2 of the housing 1 and the end of the disk washer 6, a sealing gasket 9 is provided. The entrance windows of the water-absorbing visors 8 are directed counterclockwise. Before starting work, a rotation body is installed in the housing 1 — a single-cavity hyperboloid 4, covered by turns 5 of the screw. At the same time, the pitch of the turns and the number of calls of the screw must meet the requirements of the irrigated crop in terms of intensity and structure of rain. A disk washer 6 with water-absorbing visors 8 is attached to the lower body to the body of revolution of a one-sheeted hyperboloid 4 with a pin 7, the passage section ω of which must correspond to a given flow rate Q through the sprinkler-activator.

When water is supplied to the internal cavity of the housing 1, the flow enters the coils 5 of the screw and acquires a rotational movement, while its living cross section ω decreases, as this is facilitated by the body of revolution, the single-cavity hyperboloid 4. According to the flow equation Q = ωV, where V is the flow velocity , with a decrease in the living cross section, the flow rate increases. It was established by experimental studies at the university, as well as from a review of literary sources, that when the flow rotates counterclockwise, the structure of the water changes, the value of the hydrogen index increases, the water becomes structured, and its energy and vitality increase.

When the flow leaves the body of revolution of the single-sheeted hyperboloid 4, it will have maximum energy and redox potential, the rotating stream is captured by the water-absorbing visors 8 and is thrown onto the irrigated surface. In this case, the flow is destroyed into fine particles, which under the influence of gravity settle on the irrigated surface of the field. The use of an sprinkler-activator with adjustable rain quality provides uniform soil moisture with water with increased redox potential, prevents the destruction of the soil structure and increases crop yields.
