FAN-TYPE PLANT SPRAYER Russian patent published in 2005 - IPC

FIELD: agricultural engineering.

SUBSTANCE: fan-type sprayer has axial fan provided with mechanical drive and mounted in casing, liquid supplying system, and nozzles with slot sprayers. Each of slot sprayers is positioned in spaced relation inside nozzle case. Outlet end of slot sprayer is embraced with conical part of nozzle case. Air duct branch pipe is mounted in lower portion of nozzle case. Said space is defined by conical part of nozzle case and sprayer baffle plate. Slot sprayer is divided into individual chambers by means of distribution plates arranged symmetrically relative to nozzle case longitudinal axis, with inclination angle of distribution plates uniformly increasing from nozzle case center to both sides of periphery. Two hydraulic pipes of slot sprayer are extending in parallel with one another and interconnected by connecting member for defining closed contour. Hydraulic pipe is provided with openings uniformly distributed along its length and oriented into inside of slot sprayer in symmetry with openings of opposite hydraulic pipe.

EFFECT: increased efficiency in applying of high-concentrated suspended fertilizers and aqueous emulsions at optimal extent of dispersion and uniform distribution of used preparation on plants.
