Abstract
A combine harvester includes a separating device that extends in a longitudinal direction of the combine harvester. In front of the separating device, a tangentially disposed feed drum is installed. The feed drum is configured with substantially axially parallel guide plates on a circumference thereof. The substantially axially parallel guide plates bear against the jacket surface of the feed drum via support elements. The support elements extend between adjacent guide plates in the circumferential direction and, extend between the adjacent guide plates in the radial direction across an entire free jacket surface of the feed drum.
Claims6
A combine harvester (1) comprising:
- a separating device (3) that extends in a longitudinal direction of the combine harvester (1), and
- a tangentially disposed feed drum (8, 8′) installed in front of the separating device (3) and configured with substantially axially parallel guide plates (21) on a circumference thereof,
- wherein the substantially axially parallel guide plates (21) bear against a jacket surface (19) of the feed drum (8, 8′) via support elements (22),
- wherein the support elements (22) extend between adjacent guide plates (21) in a circumferential direction from a rear side of a guide plate to a front side of an adjacent guide plate,
- wherein the support elements (22) extend between the adjacent guide plates (21) in the radial direction across the jacket surface (19) of the feed drum (8, 8′);
- and
- wherein the radial extension of the support element (22) decreases in the circumferential direction of the feed drum (8, 8′) starting from the rear side of the guide plate (21) which, which is not used to directly convey the crop stream.
