Patent number: 11959861Abstract: An agricultural machine is disclosed that includes an NIR sensor configured to detect NIR spectra of plant material and output them as raw data, an evaluation unit configured to derive at least one parameter of the plant material in real time from the raw data, and an interface for the data traffic with at least one data processing unit outside of or external to the agricultural machine that is configured to transmit the raw data to the data processing unit.Type: GrantFiled: September 28, 2021Date of Patent: April 16, 2024Assignee: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Björn Stremlau, Carsten Grove, Michael Roggenland, Frank Claussen, Maximilian von Nordheim, Jeremias Hagel, Jörg Wesselmann

Patent number: 11566883Abstract: A detection arrangement for detecting a wear status of a chopping knife arrangement of a chopping device provided for processing a product flow, wherein the chopping device has a revolving chopping drum receiving the chopping knife arrangement and at least one shear bar which cooperates with the chopping knives, with a sensor arrangement which has a magnetic exciter arrangement and a flux conducting device magnetically coupled thereto. The sensor arrangement provides a pole arrangement which forms at least one magnetic pole with a pole surface for conducting magnetic flux, wherein at least a portion of the chopping knife passes the pole arrangement during a rotation of the chopping drum. A voltage induced when a chopping knife arrangement passes the sensor arrangement forms the measured magnetic value, which is used by the evaluation unit to determine the state of wear of the chopping knife arrangement.Type: GrantFiled: March 11, 2020Date of Patent: January 31, 2023Assignee: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Christoph Heitmann, Dennis Neitemeier, Markus Brune, Jochen Huster, Frédéric Fischer, Bjoern Stremlau

Publication number: 20220229412Abstract: Creating NIR sensor calibration models and their use in agricultural work machines is disclosed. A database structure, such as a database structure system, for creating calibration models for an NIR sensor system is used. The database structure includes raw data of the NIR spectra of one or both of plant material and other substances. The raw data are generated by one or more NIR sensor systems assigned to an agricultural work machine. The one or more NIR sensor systems transmit the raw data via an interface for the data traffic with at least one data processing unit external to the agricultural work machine. The database structure comprises one or more calibration models and the raw data, generates user-specific calibration models by using the saved raw data and/or calibration models, and provide user-specific calibration models to a user.Type: ApplicationFiled: September 28, 2021Publication date: July 21, 2022Applicant: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Björn Stremlau, Carsten Grove, Michael Roggenland, Frank Claussen, Maximilian von Nordheim, Jeremias Hagel, Jörg Wesselmann

Publication number: 20200359563Abstract: A driver assistance system of an agricultural work machine constructed as forage harvester, wherein the agricultural work machine comprises a header for gathering crop, a chopping device having a chopping drum and chopping knives for comminuting the crop, and a monitoring device operable to generate a signal containing information about the wear status of the respective chopping knife and/or about the distance of the cutting edge of a chopping knife from a shear bar. This information is compared with a reference value, and the agricultural work machine has activation devices for activating and deactivating a knife grinding process and means for change of position of the shear bar. The monitoring device is integrated in the driver assistance system so that the driver assistance system automatically detects when a knife grinding process or a change of position of the shear bar must be activated or deactivated.Type: ApplicationFiled: April 23, 2020Publication date: November 19, 2020Applicant: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Christoph HEITMANN, Dennis NEITEMEIER, Markus BRUNE, Jochen HUSTER, Bjoern STREMLAU, Frédéric FISCHER

Publication number: 20190289787Abstract: A forage harvester has multiple working elements for carrying out a crop handling process, a drive system which is divided into a main drive train that includes mechanically driven working elements, and an auxiliary drive train that includes hydraulically driven working elements, a driver assistance system which comprises a memory for storing data and a computing device for processing data stored in the memory, as well as a graphical user interface. The working elements consist of at least one adjustable crop handler, at least one actuator system for adjusting and/or actuating the crop handler, and a control unit for controlling the actuator system. The working element is designed as an automatic adjuster whose mode of operation can be optimized by the driver assistance system. The driver assistance system feeds a throughput-proportional load signal, which can be determined by at least one sensor system, to the particular automatic adjuster.Type: ApplicationFiled: March 14, 2019Publication date: September 26, 2019Applicant: CLAAS Selbstfahrende Erntemaschinen GmbHInventors: Christoph Heitmann, Ingo Boenig, Bjoern Stremlau, Frédéric Fischer, Andre Dammann, Stefan Schiewer, Felix Herter, Jan Furmaniak, Bastian Kriebel
