Patent number: 8079900Abstract: A combine (10) comprises a crop processing device (26) having a straw outlet (62), a beater (64) assigned to the straw outlet (62) of the crop processing device (26) and a straw chopper (60). An overshot drum conveyor (68) follows the beater (64). A single, pivotable flap (80) is located downstream the drum conveyor (68) and movable between a chopping position in which it deflects the straw downward into the straw chopper (60) and a swath laying position in which it lets the straw pass to a slope (88) behind the straw chopper (60). The flap (80) is pivoted at its forward end adjacent and above the drum conveyor (68) and has a shape matching to the circumference of the drum conveyor (68).Type: GrantFiled: July 7, 2008Date of Patent: December 20, 2011Assignee: Deere & CompanyInventors: Oliver Klein, Dirk Weichholdt, Rico Priesnitz, Fritz Lauer, Chad A.

Publication number: 20020086723Abstract: A combine having an axial separator that is provided with an outlet. A discharge beater is located adjacent the outlet. The discharge beater can be selectively rotated in response to crop throughput volume. The discharge beater is arranged to convey crop remains thrown out of the axial separator downwardly. The discharge beater is spaced away from the outlet of the axial separator in such a way that it comes into contact with the crop remains only when the axial separator is operating at relatively high throughput volumes.Type: ApplicationFiled: September 20, 2001Publication date: July 4, 2002Applicant: Deere & CompanyInventors: Klaus Braunhardt, Lutz Bischoff, Dirk Weichholdt, Patrick J.
