AIR-HYDRAULIC SPRINKLER Russian patent published in 2019 - IPC B05B7/10 A01G25/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to irrigation technique with fine and drop sprinkling, plants fertigation in cultivation of wide range of crops. Housing of pneumatic-hydraulic sprinkler is made of two parts: one part – for supply of initial liquid and gaseous phases and another – for discharge of sprayed liquid, located along axis on threaded joint with formation of diffuser for air between them. In the housing part for supply of initial liquid and gaseous phases there is a channel for liquid supply, which is made in the union equipped with external thread with cone-shaped narrowing of the channel cross-section, changing into the nozzle, with made screw-like depressions. Union has a conic external shape at the output end. Diffuser chamber is connected with tangential air supply union, and annular gap for air supply, formed by cone-shaped pair of surfaces of outlet external part of nozzle for supply of liquid and recess in part of housing for discharge of sprayed liquid so that at that, rotating in one direction flows of liquid and air in mixing chamber have possibility of meeting. Value of annular gap is adjustable by changing and fixing position of nozzle for supply of liquid in housing part for supply of initial phases. Annular gap in direction of phases movement is connected with mixing chamber and outlet nozzle equipped with depressions of helical shape.

EFFECT: simplification of sprinkler design, expansion of technological capabilities during irrigation of agricultural plants, provision of artificial rain drops size decreasing, reduction of power inputs.
