摘要

FIELD: land reclamation.;SUBSTANCE: invention relates to sprinkling and can be used in sprinklers to produce uniform rain of uniform intensity, allowing to moisturize a wide range of soils and different types of crops without formation of soil crust on irrigated surface. Sprinkler unit nozzle has a working surface of the deflector made concave in the form of a surface of rotation with an axis of rotation lying in the plane of the axis of the reduction hole. Cross-sections of the planes containing the axis of the reduction hole are semi-parabolas with the coefficient at the highest degree in range of 0.9–1.1.;EFFECT: invention provides uniform distribution of artificial deposits on irrigated surface without formation of soil crust.;1 cl, 2 dwg
