Publication number: 20240081182Abstract: A threshing drum and a combine using a threshing drum are disclosed. The threshing drum comprising a drum body and beater bars. The beater bars each have a beating edge which describes a circumferential circle about a center axis of the drum body, on which the particular beating edge rotates about the center axis in a beating radius during operation of the threshing drum. To improve a flow of harvested material while the flow is being transferred from a threshing device to a downstream separating device, a cutting ring is positioned centrally on the drum body, viewed in the longitudinal direction of the drum body, which rotates in the circumferential direction of the drum body. The cutting ring has at least one circumferential cutting edge which describes a circumferential circle whose cutting radius, measured with respect to the center axis, is greater than the beating radii of the beating edges.Type: ApplicationFiled: September 13, 2023Publication date: March 14, 2024Applicant: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Jens Bußmann, Bernd Holtmann

Patent number: 11647694Abstract: A method for the operation of a combine harvester includes processing a harvested material flow by at least one axial separator and ejecting a residual material flow formed in this way from the combine harvester by at least two ejection devices. The axial separator is formed by a movable vane element by means of which the residual material flow exiting from the axial separator is distributed on a work member downstream of the axial separator. In order to further improve the distribution of the residual material flow on the field, an actual distribution of the residual material flow on the two ejection devices is detected, wherein, when a deviation of the actual distribution from a predetermined reference distribution is detected, the vane element is readjusted so that the actual distribution is at least approximated to the reference distribution.Type: GrantFiled: January 16, 2020Date of Patent: May 16, 2023Assignee: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Jens Bussmann, Bernd Holtmann, Andreas Diekamp, Benedikt Poelling

Patent number: 11638398Abstract: A driver assistance system for a combine harvester that has a processing stage with an input for a crop flow, a first output for a useful flow and has abundant threshed grains, and a second output for a residual flow with scarce grains. At least one operating parameter of the processing stage is adjustable. The driver assistance system has an actuatable rethreshing device arranged at the second output of the processing stage, a residual grain sensor for detecting a proportion of threshed out grain in the residual flow downstream of the rethreshing device, and an evaluating device that turns the rethreshing device on and off, compares the proportions of threshed out grains in the residual flow when the rethreshing device is turned on and when the rethreshing device is turned off, and to adapt the at least one operating parameter of the processing stage based on the comparison.Type: GrantFiled: September 9, 2020Date of Patent: May 2, 2023Assignee: CLAAS Selbstfahrende Erntemaschinen GmbHInventor: Jens Bussmann

Patent number: 11382274Abstract: A separator arrangement has an inlet head housing, a feed drum and two axial separating rotors projecting by one end portionwise into the inlet head housing. The inlet head housing has planar inlet portions which extend over the width of the respective axial separating rotor and between which is arranged a ramp-shaped housing portion extending paraxial to the conveying direction of the axial separating rotors and which assists in dividing a harvested material flow into partial flows to be fed to the axial separating rotors. At least one separating element is associated with the ramp-shaped housing portion and has a base body which extends perpendicular to the surface of the housing portion and which has an end face formed as a cutting edge. A coating comprising a wear-resistant second material is arranged on the end face and extends substantially medially in the longitudinal direction of the end face.Type: GrantFiled: February 7, 2020Date of Patent: July 12, 2022Assignee: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Markus Pellmann, Jens Bussmann, Bernd Holtmann

Publication number: 20220174873Abstract: A self-propelling combine and a method for operating a self-propelling combine are disclosed. The combine includes an axial spreader, which generates a residual flow of material and supplies the residual flow of material to a downstream distribution device that discharges the residual flow of material from the combine. The axial separator in the end-side material delivery region has at least one guide element that may be moved by an actuator, thereby affecting a distribution of the exiting residual flow of material over the supply width of the distribution device. The distribution of the residual flow of material is detected by at least one sensor unit, and when a deviation from a target distribution is detected, the guide element is adjusted. A control device receives and uses a signal representing a side wind used to automatically adjust of the at least one guide element.Type: ApplicationFiled: December 6, 2021Publication date: June 9, 2022Applicant: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Philipp Topmöller, Andreas Brand, Christian Beulke, Manuel Elpmann, Jens Bußmann
