SUPERLOW VOLUME SPRAYER Russian patent published in 1999 - IPC

FIELD: agricultural engineering. SUBSTANCE: sprayer has frame carrying reservoir with working fluid solution, pipelines, leveling vessel with valve, airduct with pressure reducer and valve, sprinkler, feeding pipeline with injector nozzles. Sprinkler has jet forming device with slit-type air nozzle having two interconnected plates with layer between them. Layer has lemniscate-shaped portion positioned at circular inlet slit and rectangular outlet opening junction place. Inlet pipe is welded to upper plate at an angle exceeding 90 deg relative to nozzle axis and oriented in the direction of air flow. Such construction allows field crops and perennial plantations to be treated at low flow rate of solution. EFFECT: reduced consumption of power for operation of sprayer, reduced usage of solution and improved dispersity of spray beam. 2 dwg
