FINE DISPERSION SPRINKLER Russian patent published in 2009 - IPC B05B1/18 

FIELD: technological processes.

SUBSTANCE: invention concerns irrigation method by fine dispersed and drop sprinkling, and can be applied in mobile aggregates for sprinkling with drop size suitable for irrigation of a wide range of cultivated plants with irrigation water of enhanced biological activity and vitality. Invention is intended for creation of multipurpose nozzle for sprinkling machines, maintaining specified flow rate, fine dispersion of sprinkling, possibility of streamlined maintenance, enhanced water energy and vitality. To achieve that purpose, deflector of fine dispersion sprinkler is positioned behind water release orifices. Lower orifice edge interfaces with deflector bottom made with a radius. Outer deflector edge is positioned above lower edge of water release orifices. Conical flow splitter is mounted inside case and interfaces with lower edge of water release orifices by radius. Side surface of conical flow splitter carries a guide rail running in spiral with left-hand thread. Number of spiral turns is equal to the number of water release orifices. Number and diametre of water release orifices is determined by specified flow rate required for the sprinkling nozzle. Internal space of water release orifices features spiral guiding groove with left-hand thread. Water release orifices are made in the case wall along tangent to internal case diametre and directed counter-clockwise.

EFFECT: enhanced operation reliability, simplified construction, fine dispersion sprinkling with irrigation water of enhanced biological activity and vitality.
