FIELD: technological processes. ^ SUBSTANCE: invention concerns irrigation method by fine dispersed and drop sprinkling with irrigation water with enhanced biological activity and vitality, and can be applied in mobile aggregates for sprinkling with drop size suitable for irrigation of a wide range of cultivated plants. Invention is intended for creation of multipurpose nozzle for sprinkling machines, maintaining specified flow rate and fine dispersion of sprinkling. To achieve that purpose internal case hollow of sprinkling nozzle with adjustable feed encases guiding cone with curved side surface and reflection shell ring at the base, conjugated with curved side cone surface along parabolic curve. Projecting edge is located at a distance from deflector bottom surface. Side surface of guiding cone carries guiding edges running in spiral with left-hand thread. Outlet case edge is rounded along radius and has a gap Delta between outlet case edge and deflector bottom surface, the gap adjusted by threaded support. External surface of deflector has a scale, and external surface of case has indicator notch. ^ EFFECT: possible sprinkling parametre adjustment, improved operation reliability, simplified construction. ^ 2 dwg |
