Cam actuated finger assembly for rotary auger
First Claim
1. A crop gathering system for an agricultural harvester, the crop gathering system comprising:
- a cylindrical tube comprising a tube wall and a longitudinal axis, the tube wall defining at least one aperture extending through the tube wall;
a rotary cam comprising an elongated shaft with a cam surface, the shaft extending inside the tube parallel to and radially offset from the longitudinal axis of the tube; and
at least one cam follower, the at least one cam follower comprising a proximal end engaging the cam surface of the elongated shaft and a distal end aligned with the at least one aperture,wherein the at least one cam follower is displaceable through the at least one aperture between a fully extended position and a fully retracted position relative to the tube wall.

Abstract
A crop gathering system for an agricultural harvester includes a tube having a tube wall. The tube wall defines an aperture extending through the tube wall. The crop gathering system also includes a rotary cam having an elongated shaft with a cam surface. The shaft extends inside the tube along an axis radially offset from the axis of the tube. The crop gathering system further includes a cam follower having a proximal end engaging the cam surface of the elongated shaft, and a distal end aligned with the aperture. The cam follower can be in the form of an auger finger that moves in and out of the tube wall as the tube is rotated to gather crop material and convey the crop material to a threshing system. A cam actuated finger assembly can be manufactured for installation in an auger of an agricultural harvester.
