摘要： A method and an apparatus for separating a crop flow on at least one conveying and cleaning unit, particularly a top sieve, of a combine harvester, wherein the conveying and cleaning unit is excited to a longitudinal oscillation and a transverse oscillation. The transverse oscillation is controlled depending on at least one state, wherein least one state for controlling the transverse oscillation is the inclination of the combine harvester, wherein at least one further state for controlling the transverse oscillation is the grain purity, particularly the grain purity of a main crop flow. The transverse oscillation is pre-controlled depending on the inclination of the combine harvester and fine-tuned depending on the grain purity.

摘要： A self-propelled combine harvester has at least one tilting mechanism for the uniform distribution of a harvested material on an oscillating conveying and cleaning unit, in particular a top sieve. The tilting mechanism has elements for defining a swiveling direction of the conveying and cleaning unit which are arranged between the conveying and cleaning unit and a machine housing. The tilting mechanism has an actuator for continuous adjustment of at least one component part of the elements from an initial position to an adjusting position. The position of the at least one component part decisively defines the swiveling direction. An electric control unit controls the actuator depending on a state of the combine harvester and/or harvested material and the initial position of the at least one component part of the tilting mechanism.

摘要： A method for executing an agricultural work process on a field by means of a group of agricultural work machines. The work machines each have work assemblies which are adjustable with machine parameters for adapting to the respective agricultural conditions. The work machines of the group communicate with one another via a wireless network. The work machines of the group are configured as self-optimizing work machines which each have a driver assistance system for generating and adjusting machine parameters in an automated manner. These machine parameters are optimized with respect to the agricultural conditions. The work machines of the group cooperate collectively in the manner of a virtual work machine.

摘要： A method and a system for determining an indicator of processing quality of an agricultural harvested material using a mobile device is disclosed. A computing unit analyzes image data of a prepared sample of harvested material containing grain components and non-grain components in an analytical routine to determine the indicator of the processing quality of the agricultural harvested material. Further, the computing unit uses a trained machine learning model in the analytical routine to perform at least one step of determining the indicator of the processing quality of the agricultural harvested material.

摘要： An agricultural harvesting machine, particularly a combine harvester or a forage harvester, has a supporting frame, a cutting mechanism, an inclined conveyor and a driver's cab. The cutting mechanism is arranged at the supporting frame by the inclined conveyor. The driver's cab is arranged at the supporting frame with the intermediary of at least one damper unit. At least one camera is arranged in an interior of the driver's cab. The camera is oriented to the cutting mechanism and/or to the inclined conveyor through a front windshield of the driver's cab. The camera is arranged in an operative area of a cleaning device of the front windshield so that a detection area of the camera can be optically acquired at least through a portion of the operative area of the cleaning device.

摘要： 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.
