SPRINKLER NOZZLE Russian patent published in 2011 - IPC B05B1/18 

FIELD: agriculture.

SUBSTANCE: invention may be used In mobile installations for generation of rain with drop size suitable for irrigation of a wide range of agricultural crops with enhanced water energy and life force. The invention is aimed at creation of a multi-purpose muzzle for sprinkler machines, maintenance of specified water expenditure rates, provision for fine-dispersion sprinkling and enhancement of water energy and life force. For this purpose the sprinkler nozzle body is designed to be of the split type consisting of two varied length truncated cones oppositely connected via their major bases. The minor length truncated cone is connected to the inlet nipple via its vertex. The major length truncated cone has a water-discharge hole conjugated with a cup-shaped deflector. The cup bottom is part of a paraboloid of revolution with a left-side winding guide auger positioned inside the body inner cavity. The auger is mounted on a cylindrical axle. There are water-discharge holes arranged at the point of the body split inside the cone. The holes number and diametre are selected from the condition of supply of a specified flow rate for irrigation of the sprinkler nozzle positioning zone. The split-type body is fastened on the water delivery nipple with the help of a clamp forming integral part of the body. The output edge of the deflector is positioned above the outer edge of the water discharge hole.

EFFECT: enhanced reliability of operation and watering uniformity within the area irrigated, improved yield and quality of agricultural products.
