Abstract
A drive mechanism for a chain conveyor includes an elongated shaft that extends along an axis and is configured to be driven to rotate by a motor. A sprocket is integrally formed with the shaft. The sprocket includes a plurality of lobes that extend around a perimeter of the shaft. Each lobe is spaced apart from an adjacent lobe by a recessed portion. Each of the recessed portions is configured to receive a drive pin of the chain conveyor.
