Patent number: 9043959Abstract: 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.Type: GrantFiled: June 18, 2013Date of Patent: June 2, 2015Assignee: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Dirk Esken, Bernd Holtmann, Martin Niermann

Publication number: 20140364179Abstract: A combine harvester includes a first discharge mechanism having a changeable discharge direction, a chopping assembly for chopping up straw and a second discharge mechanism disposed downstream of the chopping assembly. The second discharge mechanism disposed is operated at least two different positions. In a first position, the second discharge mechanism is supplied with crop from the chopping assembly and the first discharge mechanism. In a second position, the second discharge mechanism disposed permits crop to be discharged upon bypassing the second discharge mechanism. The discharge direction of the first discharge mechanism is dependent upon the operating state of the chopping assembly.Type: ApplicationFiled: May 8, 2014Publication date: December 11, 2014Applicant: CLAAS SELBSTFAHRENDE ERNTEMASCHINEN GMBHInventors: Joern Brinkmann, Christian Beulke, Martin Niermann
