摘要： An agricultural harvesting machine, with at least one work assembly and a monitoring assembly, is disclosed. The agricultural harvesting machine transports harvested material in a harvested material flow along a harvested material transport path. The monitoring assembly includes an measuring system positioned on the harvested material transport path and an evaluation device configured to determine at least one harvested material parameter. The measuring system includes a first passive optical sensor that senses image data indicative of visible light in a first section and a second non-passive non-optical sensor that senses data in a second section that at least partly overlaps the first section. The evaluation device correlates the image data for the overlapping section from the first optical sensor and the data from the second optical sensor and determines, based on the correlation, at least one harvested material parameter.

摘要： A drive system for self-propelling harvester is disclosed. The harvester includes a drive motor, a transfer case driven by the drive motor and having an output pulley arranged on a driveshaft of the transfer case and driving, using a main drive belt, at least one main pulley of a rotating cutter drum arranged on the end of a cutter drum shaft, a conditioning apparatus, an ejection accelerator, and a hydraulic pump for hydraulically driving an attachment and/or a feed device. The output pulley, the main drive belt and the main pulley form a main drivetrain for driving the cutter drum, the conditioning apparatus, and the ejection accelerator, and the attachment and the feed device are each driven by a separate drivetrain. At least one prop shaft, on the side of the main drivetrain, is arranged or positioned to lie in a common vertical plane with the main drive belt.

摘要： A method and a data processing device are disclosed for at least partially automatically transferring a word sequence composed in a source language into a word sequence in a target language with corresponding substantive content. By analyzing the word sequence and identifying terms with lexical ambiguity in the word sequence by comparing with a terminology database comprising terms with lexical ambiguity in the source language which are assigned a plurality of term identifiers depending on their number of meanings, an unambiguous term definition is provided for translating the word sequence into the target language by assigning a term identifier to the term with lexical ambiguity in the source language. This may render a machine translation less susceptible to errors.

摘要： A self-propelled harvesting machine for harvesting a crop field has a ground drive including multiple working units, a control system and a sensor system. The sensor system periodically emits transmitted pulses of electromagnetic transmission beams in at least one transmission direction onto the crop field and the transmitted pulses are reflected on the crop field and are received as echo pulses by the sensor system. For at least one portion of the transmitted pulses, different partial beams of a single transmission beam are reflected by plants of the crop field lying one behind the other with a time offset, so the particular resultant echo pulse is composed of time-offset partial echo pulses. The control system determines a value for the crop density on the basis of a time correlation within the resultant echo pulse, and controls the ground drive and/or the working units on the basis of the determined crop density.

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 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.

摘要： The present invention relates to a method for operating a cutting unit (1) that has a cutter bar (6) that is operated rigidly or flexibly, depending on the harvest conditions, which can be operated in at least two different operating modes, wherein the cutting unit (1) includes a first sensor assembly (1) disposed on the cutting unit (1) that can be deactivated, which is for operating the cutting unit (1) in a first operating mode, and a second sensor assembly (17) for operating the cutting unit (1) in a second operating mode, wherein, when switching between the at least two operating states, the first sensor assembly (13) or the second sensor assembly (17) is activated without interruption in operation, to execute a distance determination, depending on the selected operating mode.

摘要： An agricultural work machine, in particular a harvester, has a header for performing agricultural work and having a control device which has at least one sensor unit for detecting a crop stream in and/or around the header and an image processing unit for processing images which are generated by the sensor unit based on the crop stream detected via sensor. The control device is configured to detect regions of like characteristics, components of the header and properties of the crop stream and is configured to use that which has been detected for open loop control and/or closed loop control of process sequences in the agricultural work machine.

摘要： A combine harvester includes a belt cutting unit comprising a center belt for conveying harvest to an intake roller and/or to an intake channel of a grain conveyor, and a transverse conveyor belt disposed each on the left-hand side and the right-hand side of the center belt, to convey harvest to the center belt. The center belt, left-hand and right-hand transverse conveyor belts are behind a cutter bar, seen in the direction of travel, with each being operated with an individual belt speed. The combine harvester and/or belt cutting unit has a control unit configured to automatically control the belt speeds of the left-hand and right-hand transverse conveyor belts as a function of a forward travel speed, and the belt speeds of the center belt as a function of the forward travel speed or as a function of the belt speeds of the left-hand and right-hand transverse conveyor belts.

摘要： An agricultural work machine for performing an agricultural work process is disclosed. The agricultural work machine includes working units and a driver assistance system for controlling the working units to achieve one or more quality criteria. The driver assistance system may set parameters to control the working units in order to satisfy the criteria. Further, the driver assistance system includes a graphical user interface through which an operator may change the setting of one of the quality criteria. Responsive to the change, the driver assistance system may determine the expected effects on other quality criteria. In addition, the driver assistance system may visually highlight the expected effects on the graphical user interface.
