SPRINKLER NOZZLE-ACTIVATOR Russian patent published in 2015 - IPC B05B1/18 

FIELD: agriculture.

SUBSTANCE: sprinkler nozzle-activator comprises a housing and a deflector attached to the helical rack. The deflector is in the form of a bladed disc which blades are made on elliptic curves, the output edges of which are directed tangentially to the outer surface of the disc. The height of the blades corresponds to the required flow rate through the sprinkler nozzle-activator. In the interlobe space the spirals of left-hand orientation are fixed. Fixing the deflector to the housing is arranged by means of bolts, for this purpose on the deflector disc the protrusions are provided with the holes. The height of the protrusions is equal to the height of the blades, and the shape of the protrusions corresponds to the curved shape of the blades. In the central part of the blade disc a flow divider is fixed through the screws, made in the form of a surface of rotation of a parabola z²=px near the axis z.

EFFECT: improvement of the structure of rain, uniformity of its distribution on the irrigated field and increase in yield.
