SPRAYER

FIELD: agricultural engineering. SUBSTANCE: sprayer has fan, pump, atomizer and nozzle. Fan is designed to provide air/liquid flow rate ratio of from 0.14 to 1 and speed Vair of air flow from fan and speed Veiguid of liquid from atomizer Veiguid:Vair/Veiguid=1 plus and minus 10%. Nozzle with flat walls is positioned on the path of air flowing from fan. Nozzle discharge section has width varying from maximal value at the top part to minimal value at the bottom part. Partitions are positioned in flow-through portion of nozzle at different angles to surface to be treated to define individual channels of different width. Sprayer provides air-liquid flow for supplying atomized liquid onto surface to be treated and speed of contacting with plant surface not in the excess of 5 m/s. EFFECT: reduced power consumption and material usage, maximal remoteness of spraying of air-liquid mixture, uniform distribution of said mixture over plant surfaces. 3 dwg
