SPRINKLER NOZZLE-ACTIVATOR FOR MOBILE SPRINKLING MACHINES Russian patent published in 2014 - IPC B05B1/18 

FIELD: agriculture.

SUBSTANCE: in sprinkler nozzle activator for mobile sprinkling machines the L-shaped housing is mounted in the rear part of the sprinkling machine. The helical flow guide is made of auger-type of left-side orientation and is placed on the body of rotation formed by rotating of equilateral hyperbola $$y=\frac{x}{h}$$ near the vertical axis. The height of the turns of the auger is connected with the inner cavity of the vertical part of the housing. In the lower vertical part of the housing using a threaded ring a transformer of water flow to raindrops is mounted. The transformer comprises curved blades formed on logarithmic spiral of left-side orientation. Between the blades on the bottom the water-gripping blades are provided, made in the form of a hollow half-cone and mating with holes in the bottom. The blades are located on concentric circles, the horizontal part of the bottom is connected with its vertical part on the radius. On the vertical part of the bottom the drop-forming holes are made, located in two tiers. The holes in the bottom under the water-gripping blades are connected in the rear and the front part with the blade and the vertical wall along the radius.

EFFECT: generating rain with drop sizes, suitable for irrigation of a wide range of cultivated crops.
