Patent attributes
A combine harvester including at least one straw walker extending in a longitudinal direction of the harvester and supported by a front and rear shaft. The shafts are rotatable about respective rotation axes, and each shaft provided with one or more eccentric portions. The straw walker is rotatably mounted on an eccentric portion of the respective front and rear shafts, so that the simultaneous rotation of the shafts actuates a reciprocating motion of the straw walker. The combine further comprises a pivot frame and one or more actuators, configured to adjust the angular position of the frame by pivoting the frame about a pivot axis oriented transversally to the longitudinal direction. The front and rear shafts are configured to rotate with respect to the pivot frame, so that the straw walker's angular position is adjustable while the straw walker executes the reciprocating motion.
