Abstract
A pickup reel for a harvesting platform including a reel support structure with a reel shaft rotatably supported thereon. A plurality of radially extending arms are mounted to the reel shaft and a plurality of transverse rockshafts are mounted to the radially extending arms and are axially offset and parallel to the reel shaft and span the width of the platform. Radial fingers are mounted on each rockshaft. A cam is mounted to the support structure adjacent one or both ends of the rockshafts and defines an endless cam path about the reel shaft. A crank arm attached to each rockshaft carries a cam follower that engages the cam path for following along the path. The cam path is configured to cause the crank arms, and thus the rockshafts, to rotate about the respective rockshaft axis to vary the attitude of the fingers relative to the ground as the cam followers move along the cam path. The cam is segmented, having two or more cam segments joined together to form the endless cam path. The cam segments are joined together by removable fasteners to enable one segment to be removed and replaced to either vary the cam path or to replace a worn cam segment.
