Abstract
A conveyor drive unit is provided for engaging and driving a belt type conveyor. The unit includes a motor drive unit and drive chain assembly having a drive chain driven by the motor along a drive path. The drive chain has drive lugs configured thereon to engage with drive dogs on the conveyor as the drive chain is driven along the drive path. The drive path defines the drive angle with respect to a straight path of the conveyor along the drive path. An adjustable positioning device is disposed relative to the drive chain assembly such that upon variable positioning of the drive chain assembly, the drive angle defined between the drive path of the chain and the straight path of the conveyor along the drive path varies. In this manner, the degree of engagement of the drive lugs with the drive dogs of the conveyor along the drive path can be adjusted by varying the drive angle.
