Information confirming the possibility of implementing the claimed invention are as follows.

Cascade-wave sprinkler nozzles comprises a split cylindrical body 1, the connecting of the two halves of the ribs 2 with bolts 3. In the inner cavity of the cylindrical body 1 is mounted a conical sharpening up 4 hour 5 deflector consisting of an arcuate fasteners 6 to the inner wall of the housing undulating blades 7 connected to the housing by screw fasteners 8. To the lower part of the housing 1 by means of flanges 9, 10 are fixed conical replacement sprinkler with 11 vodozabornyjj trump�AMI 12. The housing 1 is attached to the power conduit through the flange 13. Vodasoivata visors 12 is deflected from the wall of the conical replacement of the device 11 at an angle of 25...35°, and the rear guide wall 14 are formed by the curve of the function y=arctgx, where y - coordinates of the points of the curve vertically, the x - coordinates of the point on the curve horizontally (Fig.3). Vodasoivata visors 12 is input Windows counterclockwise and are associated with the outlet openings 15. The front wall 16 of the outlet hole 15 is formed at an angle of 20...25° to the wall of the conical replacement of the sprinkler 11. The upper edge vodokanalnyh visors 12 has cut 17 that is parallel to the conical wall of the sprinkler 11. Wavy blade 7 is formed of a segmented and joined with the inner wall of the housing through arcuate fasteners 6 cascade, wherein the fastening of the blades 7 to the inner wall of the housing 1 is made along a helical line of left-hand orientation. The parameters of the conical replacement of the device are selected depending on the watering requirements of a given irrigated culture.

Cascade-wave sprinkler nozzle operates as follows.

Water from the power tubing is fed into the cylindrical body 1, wherein the stream flows around the conical sharpening 4, interacts with wavy blades 7 and acquires tourbe�turbulent motion, which changes the structure of water and increases its biological activity. Moving from the blade to the blade, the flow forms a mini-waterfalls that enhance the biological activity of water. As a result of interaction with a cascade of blades, the flow acquires a rotational movement of left-hand orientation, which also significantly increases biological activity in the water. Rotating flow enters the conical removable device 11, which interacts with vodozabornyjj visors 12, which are thus separated from the flow of separate streams, the size of which depends on the parameters vodokanalnyh visors - height and width. Trickle of water moving through the wall 14 made by the curve of the function y=arctgx, and the front wall 16, formed at an angle of 20...25°, are directed tangentially to a tapered removable sprinkler 11. When meeting with atmospheric air streams are broken into separate drops and fall under the action of gravity on the irrigated soil surface.

Irrigation water with high biological activity in the interaction with plants irrigated culture greatly increases the yield. Collapsible design allows to perform the required operation in the operation of the cascade-wave sprinkler nozzle and to simplify its maintenance and replacement con�ical sprinkler allows you to get quality rain with the specified parameters.
