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

FIELD: agriculture.

SUBSTANCE: in fan sprinkler nozzle-activator the water-discharge openings are made in conjunction with the cylindrical housing expanding in the horizontal plane and tapered in the vertical plane of the fan nozzle. The openings are placed on the front surface of the fan nozzle, made along the circular arc. The axes of the openings are directed along the radii of this circular arc. Inside the water-discharge openings the screw guides are fixed, made double-threaded. The output edges of the turns of the screw guides are horizontal. The number and diameter of the water-discharge openings is taken equal to the cross-sectional area of the inner cavity of the cylindrical housing.

EFFECT: increase in reliability of operation, productivity and working width of the nozzle, providing the opportunity to obtain fine water sprinkling, which has increased biological activity.
