Abstract: A belt conveyor having an endless conveyor belt with an upper run and a lower run. A frictional wheel frictionally engages the lower belt run opposite a belt support roller acting as a counterpressure roller and a pivot arm carrying the friction wheel. A spring urges the wheel against the lower belt run so that, on driving of the wheel in clockwise sense, the lower belt run is frictionally driven in corresponding direction. The pivot axis of the pivot arm is at a downstream--with respect to the drive direction of the lower belt run--side of a plane containing the axes of the friction wheel and counterpressure roller. The contact pressure force between lower belt run and friction wheel varies proportionally to change in the peripheral force to be transmitted to the belt run for drive thereof.

Abstract: A potato harvester having an infeed conveyor and a discharge conveyor includes a curved-path corner conveyor for conveying harvested potatoes along a continuously curved path from the infeed conveyor to the discharge conveyor. The corner conveyor includes an endless arcuate belt with upper and lower flights. A corner frame supports and guides the upper flight of the endless belt in an arcuate path from an infeed end which receives potatoes from the infeed conveyor to an outfeed end which delivers potatoes onto the discharge conveyor. Upstream and downstream lower idler assemblies are positioned to support the lower flight of the endless belt at spaced locations along its length, while allowing a belt loop to form between and beneath the lower idler assemblies. A drive wheel assembly within the belt loop is downwardly biased to frictionally engage and drive the endless belt. A driven slack take-up wheel frictionally engages the lower flight of the endless belt downstream from the drive wheel assembly and provides increased friction between the drive wheel assembly and the endless belt.
