CREVICE SPRINKLER NOZZLE Russian patent published in 2015 - IPC B05B1/18 B05B1/26 

FIELD: agriculture.

SUBSTANCE: invention relates to a technique of irrigation with fine and drip sprinkling and can be used in mobile units for obtaining rain with droplet size allowable for irrigation of wide range of cultivated crops with increased energy and vitality of water. In the crevice sprinkler nozzle the diffuser is made trapezoidal, expanding in horizontal plane and narrowing in vertical plane. The cylindrical housing, performing a function of the connecting pipe, is coupled with the walls of the diffuser by parabolic curves. At the outlet part of the trapezoidal diffuser the horizontal shell is made, forming a gap. Cross-sectional open area of the slit is equal to the cross-sectional open area of the inner cavity of the cylindrical housing. On the inner wall of the shell the flow dividers are formed, having a shape of half of a cone of rotation with a spherical base. The flow dividers are placed on the walls of the horizontal shell in chessboard manner.

EFFECT: improving reliability of operation, design simplification, ensuring uniformity of irrigation on irrigated area, obtaining fine sprinkling with water, providing higher yields of agricultural products.
