FIELD: agriculture. ^ SUBSTANCE: invention pertains to the method of fine and sprinkling irrigation and can be used in mobile installations to obtain size of water droplets, permissible for wide range farm irrigation and vitality of water. Spiral water-sprinkling nozzle, contains a case with a water discharging opening mounted with the help of a threaded tip to the water supply conduit. To the end part of the case is mounted a conical flow divider with spiral guides, made in the form of a multiple-flighted screw. Conical flow divider is made in form of hyperboloid rotation-body, formed by the rotation of equilateral hyperbola near the vertical axis, built according to the equation h=0.5D/2.5. Spiral line of the guides has a left sided winding, and the diameter of the flight screw increases from the end face of the outlet to the horizontal part of the conical divider as per the paraboloid rotation, built according to the equation h=(0.5D)2, where h - height of the conical divider; D - diameter of the horizontal part of the conical divider. ^ EFFECT: invention simplifies the construction, increases the reliability in operation, obtaining fine sprinkling irrigation water, which possesses increased energy. ^ 1 dwg
