FINELY DISPERSED RAIN SIMULATOR Russian patent published in 2018 - IPC B05B1/18 

FIELD: irrigation technique.

SUBSTANCE: invention relates to the irrigation technique with finely dispersed and drip irrigation and can be used in mobile installations for obtaining rain with droplet sizes, permissible for irrigation of a wide range of cultivated crops. Finely dispersed sprinkler contains a cylindrical body mounted on the water supply pipe with water outlets. In the internal cavity, with the help of a threaded head having grooves for a screwdriver, a flow guide-divider is installed in the form of a paraboloid of revolution, formed by rotating the parabola of the equation z²=2ρx near the z axis, where x are the horizontal coordinates of the parabola, ρ is the constant of parabola. Base of the paraboloid is conjugated in the horizontal plane with the water outlets forming the lattice. Total area of the grid holes is taken from the condition of supplying a predetermined flow rate Q of the sprinkler water according to the equation Q =ωV, where ω – the total area of the holes, V – the rate of flow of irrigation water. Upper edge of the grating has an input chamfer, made along the parabola of the equation z²=2ρx. Upper edge of the cylindrical body has an entrance chamfer, made at an angle of 45°.

EFFECT: increase of reliability of work, simplification of a design, reception of finely dispersed sprinkling with irrigation water.
