Abstract
A centrifugal applicating device is disclosed which is hingedly connected below the product reservoir of an agricultural spray aircraft. The device includes an upper plate having a pair of feed openings and a pair of star wheel applicators rotatively carried by the upper plate below the feed openings. Each star wheel applicator includes a plurality of hollow nozzles in fluid communication with the feed openings to receive measured portions of granular agricultural materials. Each nozzle is formed with an enlarged, planar paddle on one side in position to be impinged by wind forces to rotate the star wheel applicators as the aircraft flies. A synchronizing mechanism interconnects the star wheel applicators to synchronize the speed of rotation and to assure a uniform spray pattern.
