COMPRESSED AIR LIQUID SPRINKLER Russian patent published in 2009 - IPC A01M7/00 B05B3/00 

FIELD: agriculture.

SUBSTANCE: invention deals with design of devices for humidification of air over agricultural plantations and is fit for both small-capacity watering and moistening of crops and outspraying water solutions of fertilisers, pesticides and other chemical preparations. The device consists of a housing containing liquid and air delivery fixtures installed inside it. The housing is designed as double-sectioned. The lower section is equipped with a liquid discharge faucet, a filler port and an injector element. The upper section is equipped with a detachable lid having a nipple for discharge of monodisperse medium, inspection ports arranged in the side walls, a diaphragm and a sprayer. The injector element and the sprayer are pneumatically connected to the air pressure control. The upper and the lower sections are hydraulically interconnected via the upper section liquid level control. The sprayer, hollow inside, has axial apertures and is equipped with a flange. The nozzle housing cavity contains a stepped threaded bushing, an airflow swirler and a nozzle, all oriented in the air delivery direction. On the housing butt-end surface there are radial slots arranged and blade mounted designed for film separation of a thin water layer. The injector element has a housing. The injector housing inner cavity contains a needle that has a de Leval nozzle mounted on its thinned end and a diffuser, both coaxially installed. The diffuser is connected to the intake hose. Via the mixing chamber the diffuser is conjugated with the boss on the upper section rear wall.

EFFECT: device enables improved energy efficiency and yield capacity of water-and-air monodisperse medium production which medium is fit for small-capacity watering and moistening of agricultural crops.
