IMPROVED VACCINE SPRAYING APPARATUS FOR NEWBORN CHICKS.

摘要

A vaccine spraying apparatus for vaccinating day-old chicks that includes a vaccine container with an agitation mechanism for mixing vaccine and diluent through controlled agitation. Vaccine is drawn from the container by a volumetric pump and dispensed through a plurality of spray nozzles mounted over a conveyor. Chicks contained in trays are moved along the conveyor to pass under the spray nozzles. The volume and orientation of the vaccine spray is controlled by a digital micro-control unit receiving data from a tracking device adjacent the conveyor that senses the position and speed of the trays.
