SPRINKLER UNIT WITH VARIABLE FLOW RATE AND NOZZLE INCLINATION ANGLE Russian patent published in 2003 - IPC

Abstract RU 2202173 C2

FIELD: agricultural engineering, in particular, irrigated agriculture. SUBSTANCE: sprinkler unit has tube with nozzle, sensor-vane and needle, which is joined through pivot hinges to ejector and through lever via hydraulic amplifier to sensor-vane. Pivot hinges are arranged on single shaft. Pivot joint mounted on lever is connected through tie-rod to other lever, which allows nozzle together with needle mounted thereon to be rotated in vertical plane. Such construction provides for uniform distribution and equal density of spray at both windward and leeward sides of area under irrigation. EFFECT: increased efficiency and simplified construction. 2 dwg
