FINGER DRIVE FOR A CROP FEED ROLLER

摘要

A crop feeding roller for a header includes a plurality of finger units within the roller each having a pair of fingers projecting outwardly for engaging crop outside the peripheral wall of the roller. The peripheral wail has opposed finger guide holes associated with the pair of fingers. Each finger unit including an inner member carrying the fingers and containing an elongate guide slot transverse to the axis of the roller and a stationary guide member within the guide slot at a position within the roller arranged to cause the inner member with the fingers of each of the finger units to reciprocate during the rotation of the roller. The guide slot is shaped with at least one curved lobe to one side of a transverse center section so that the slot can be S-shaped or C-shaped to improve the dwell time and swept area obtained by the finger movement.
