SUPER LOW VOLUME SPRAYER Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: sprayer has pressurized air source, air ducts, frame, reservoir adapted for storing working fluid and mounted on frame. Reservoir is communicated via leveling vessel and feed pipeline with ejection sprayer unit having replaceable jet discharge arranged in inclined position with respect to axis of air jet slit-type nozzle of jet forming device. Sprayer is further equipped with fan having spraying device and additional ejection sprayer units, which are arranged in tiers on fan spraying device, and inclined jet discharges are formed at different levels of different diameters, are arranged above air jet slit-type nozzle of respective jet forming device and are beveled at the level of axis of said nozzle. Sprayer is used for treating objects with small preparation doses and at low working fluid flow rates. EFFECT: reduced power consumption for forming air-drop jets and improved conditions for flowing of working fluid from jet discharge due to reduced local resistances. 2 dwg
