Combine Harvester with Adjustable Inclination of Straw Walkers

摘要

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 said 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 said reciprocating motion.

1. A combine harvester comprising:
a front shaft rotatable about a rotation axis and comprising at least one eccentric portion; a rear shaft rotatable about a rotation axis and comprising at least one eccentric portion; at least one straw walker extending in a longitudinal direction of the combine harvester and supported by the front shaft and rear shaft, the at least one straw walker rotatably mounted on the at least one eccentric portion of each of the front shaft and the rear shaft, so that simultaneous rotation of the front shaft and the rear shaft actuates a reciprocating motion of the straw walker; a pivot frame; and one or more actuators configured to adjust an angular position of the pivot frame by pivoting the pivot frame about a pivot axis oriented transversally to the longitudinal direction of the combine harvester, wherein the front shaft and the rear shaft are configured to rotate with respect to the pivot frame, so that an angular position of the pivot frame is adjustable while the straw walker undergoes the reciprocating motion.
