Publication number: 20140342787Abstract: A combine harvester includes at least one device for separating a crop stream into at least two crop streams that each contains different compositions of crop components. The device delivers at least one crop stream to at least one of a number of grain pans assigned to the device. The grain pan transfers the crop stream to a cleaning mechanism. At least one roller pair extending transversely to a longitudinal axis of the combine harvester separates the crop stream. A first roller and a second roller of the roller pair have a relative speed with respect to one another.Type: ApplicationFiled: May 8, 2014Publication date: November 20, 2014Applicant: CLAAS SELBSTFAHRENDE ERNTEMASCHINEN GMBHInventor: Alfons Roberg

Patent number: 6802771Abstract: An agricultural harvesting machine for removing and separating grain from harvested crop has a threshing zone and at least one separation zone for separating the grain. The axial separating rotor is at least partially encased by a separating housing having a plurality of sections. At least one of the sections is displaceable in the axial direction of the at least one axial separating rotor to increase the opening and ensure separation when a correspondingly large proportion of grain are in the outer region of the rotating crop stream and the proportion of admixtures is small.Type: GrantFiled: August 8, 2002Date of Patent: October 12, 2004Assignee: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Berthold Schwersmann, Gregor Gogolin

Patent number: 5544575Abstract: Apparatus for shelling seed corn in a manner which minimizes damage to the individual kernels includes a generally closed housing open at the top to receive ears of corn and having lower apertures for discharging the corn cobs to waste and recovering the kernels extracted from the cobs. Disposed within the housing are a pair of vertically aligned arrays of rollers, with the pair of roller arrays horizontally spaced from one another. Ears of corn are deposited through a slot in an upper portion of the housing and pass between the two arrays of vertically aligned rollers. The horizontal spacing between adjacent, horizontally aligned rollers in the first and second arrays of rollers decreases in proceeding from top to bottom, with the spacing between the two uppermost rollers being such as to easily allow an ear of corn to pass therebetween and the spacing between the bottom pair of rollers being essentially equal to the diameter of a corn cob.Type: GrantFiled: September 8, 1995Date of Patent: August 13, 1996Inventor: Robert H. Spry

Patent number: 5519987Abstract: An automotive combine has a frame adapted to move in a travel direction along the ground, a front housing pivotal on the frame, and a cutter releasably mounted on the front housing for cutting standing crop. A main thresher on the pivotal front housing has a front input and a rear outlet for taking in the cut standing crop at the input, threshing it, and outputting it at the outlet as a kernel-rich stream and a separate chaff stream. A blower conveyor on the frame has an intake receiving the kernel-rich stream and an output provided with a conduit for blowing the kernel-rich stream from the outlet. A grain bin is mounted on the machine frame and a sieve on the frame underneath the outlet of the blower separates kernels from chaff in the kernel-rich stream and delivers the kernels to the grain bin while depositing the chaff on the ground outside the combine.Type: GrantFiled: February 1, 1995Date of Patent: May 28, 1996Assignee: MDW Madhrescherwerke GmbHInventors: Lothar Voss, Christian Noack, Klaus Eckert, Volker Windisch, Wolf-Carsten Lobel

Patent number: 5356338Abstract: An axial agricultural combine having independently driven threshing and separating sections. A midpoint support bearing is located between the threshing and separating sections of the rotor. The midpoint support bearing is provided with a saddle mounted to the sidesheets of the combine and extending across the bottom portion of the rotor housing. A sealing disc is mounted to the saddle and has a sealing ring that covers the threshing section/separating section interface and a web that is provided with a bearing assembly. The drive shaft for driving the threshing section passes through this bearing.Type: GrantFiled: April 26, 1993Date of Patent: October 18, 1994Assignee: Deere & CompanyInventors: Klaus A. Braunhardt, Mark F. Stickler, Raymond M. Andes, Jr., Merle R. Gerber

Patent number: 5334093Abstract: A combine having a transverse threshing cylinder and concave and an axial separator. The axial separator comprises a pair of side-by-side axial separator units each having a rotor and a casing in which the rotors are housed. Each axial separator units is provided with three detachable covers having inwardly projecting spiral vanes. The covers are axially arranged and the first cover is adjacent to the transverse threshing cylinder and concave. The first cover is provided with at least five spiral vanes. The first vane has an angle of inclination to the transverse axis of approximately forty-five degrees; the second, third and fourth vanes have an angle of inclination of approximately thirty degrees; and the fifth vane has an angle of inclination of approximately twenty-five degrees. In small grains, such as rice, the second and third covers each have at least four vanes all with an angle of inclination of approximately twenty degrees.Type: GrantFiled: May 10, 1991Date of Patent: August 2, 1994Assignee: Deere & CompanyInventors: Roderick J. Jensen, Richard L. Day, Edwin M. Gerber

Patent number: 5052976Abstract: The invention relates to a threshing device for pulse crops, said threshing device being provided with a drum rotatable about its at least substantially horizontally arranged axis of rotation, the surface of said drum being provided with openings. In the interior of the drum there is arranged a main threshing means, which is rotatable about its axis of rotation extending at least substantially parallel to the axis of rotation of the drum, in such a manner that during operation parts of the main threshing means located near the drum surface of the drum move in the same direction as the adjacent part of the drum surface. The main threshing means is furthermore provided with projecting parts which, besides imparting a component of movement of the crop directed towards the interior surface of the drum, also impart a component of movement to the crop in the longitudinal direction of the drum.Type: GrantFiled: June 29, 1990Date of Patent: October 1, 1991Assignee: Mali-Ploeger B.V.Inventor: Anton M. van de Brand
