CASCADE-WAVE SPRINKLER Russian patent published in 2015 - IPC B05B1/18 B05B1/26 

FIELD: agriculture.

SUBSTANCE: invention relates to method of irrigation using fine and drip sprinkling, and can be used in the mobile installations to ensure rain with drops size permitted for sprinkling of wide spectrum of crop. In the cascade-wave sprinkler the casing is made detachable, connected out of two halves by ribs using bolted joints. In internal cavity of the casing the deflector pole is installed by cone tip upwards. The deflector contains arc-shape fixtures to internal side of the casing of the wave blades connected with the casing by screws. The wave blades are made as segmental, and are secured on the casing wall by cascades. The blades are secured to the casing wall along the helical line with left hand direction. In bottom part of the casing the cone replaceable sprinkler with water catching aprons is secured using flanges. The water catching aprons are deflected from the wall of the cone replaceable sprinkler at some angle. The rear guide wall is made as per curve of the function y=arctgx, where y is coordinate of the curve point through vertical, x is coordinate of the curve point through horizontal. The water catching aprons are directed CCW by the input windows and are connected with water outlet holes. Face wall of the water outlet holes is made at angle towards wall of the cone replaceable sprinkler. Top edge of the water catching aprons has cut parallel to the wall of the replaceable cone sprinkler.

EFFECT: possibility of selection of the optimal rain parameters, increased operation reliability, simple design, increased crop-producing.
