TÊTE DE RÉCOLTE DE PLANTE CULTIVÉE MUNIE D'UN ÉLÉMENT DE RÉGLAGE DE CAME SENSIBLE AU MOUVEMENT D'UN RABATTEUR

摘要

A crop harvesting header includes a reel for controlling movement of the crop in the area over the cutter bar to the transport draper carried on two reel mounting arms for upward and downward movement and for moving the reel forwardly and rearwardly along the respective reel mounting arm. The reel has a plurality of reel bats with reel fingers projecting generally radially outwardly from the reel axis where the reel bats are pivotal to vary the angle of the finger driven by a cam track member. An adjustment component defined by a follower in a guide track along one of the arms is responsive to movement of the reel along the arm which causes the cam track member to be angularly advanced and retarded about the reel axis to different adjustment angles in dependence upon the position of the reel along the mounting arms.
