LIQUID SPRAYING DEVICE Russian patent published in 2021 - IPC A01M7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for spraying liquid mineral fertilizers, pesticides and other agrochemicals. The device contains a housing 1, a cylindrical chamber 2 with a channel 3 for supplying a working fluid and an air chamber 4 with a tangential channel 5 for supplying air. The device also contains a linear actuator 6 with a vertical rod 7, a deflector 8 in the form of a body of revolution with a deflecting surface 9 and a cylindrical shank 10, a nozzle channel 11 for supplying air to a deflector 8, a nozzle chamber 12 for a working fluid, a liquid fairing 13 connected to the rod 7 of the actuator 6, insert 14, nozzle 15 with an elliptical outlet for spraying liquid, vertical channels 16 for supplying the working fluid to the nozzle chamber 12. The air chamber 4 is made toroidal, coupled with the nozzle channel 11 with an annular hole for air supply to the deflector 8. The deflector rotation body is made along the generatrix in the form of an arc 20 of an ellipse 21. The end part of the deflector 8 is provided with a linear circular surface 22 of air escape. The liquid nozzle 15 is made in the end face 23 of the deflector 8 and is associated with the nozzle chamber 12 in the form of an ellipsoid of revolution. The liquid fairing 13 is located inside the nozzle chamber 12 and is made in the form of an ellipsoid of rotation coaxially and equidistantly to the ellipsoid of rotation of the nozzle chamber 12. The maximum spray angle β of the liquid nozzle 15 is at least less than the minimum spray angle of the air flow α of the deflector 9.

EFFECT: use of the invention will improve the quality of liquid atomization.
