| 摘要 |
The present invention is related to a combine harvester comprising at least one straw walker (10) extending in a longitudinal direction of the harvester and supported by a front and rear shaft (11,12), said shafts being rotatable about respective rotation axes (13,14), each shaft provided with one or more eccentric portions (15,16), wherein 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, wherein the combine is further provided with a pivot frame (20) and one or more actuators (22), configured to adjust the angular position of the frame by pivoting the frame about a pivot axis (21) oriented transversally to said longitudinal direction, and wherein the front and rear shafts (11,12) 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. |
