  • Conveyor and spreader
    Patent number: 8991732
    Abstract: A particulate material conveyor uses an endless loop that has a feed path arranged near a bottom of a load of material to be fed and a return path arranged above the feed path and within the load where the return path is protected by a cover. Material can flow under the cover onto the feed path without filling the return path under the cover. A spinner can be combined with a conveyor to form a spreader, and the conveyor and the spinner can be driven by a single motor through reduction drives. The spreader components are mounted on a sprocket drive shaft to pivot between deployed and stowed positions.
