  • Patent number: 10568271
    Abstract: A detection arrangement for detecting a state of wear of a chopping assembly comprises at least one magnet arrangement which includes a magnetic excitation arrangement and a flux-conducting device magnetically coupled thereto. The magnet arrangement provides a pole arrangement which forms at least one magnetic pole for outwardly conducting magnetic flux. At least one portion of the chopping blades moves past the pole arrangement during a rotation of the cutting cylinder, and forms an air gap arrangement including at least one air gap with respect to the pole arrangement and, as a result, at least one magnetic circuit excited by the excitation arrangement is closed via the chopping blade. At least one portion of the magnetic flux generated by the magnetic excitation arrangement is longitudinally guided in the chopping blade at least across one longitudinal portion of the chopping blade.

  • Publication number: 20190246561
    Abstract: A combine harvester has at least one header for cutting plants to be harvested with the aid of the combine harvester, a feeder for conveying the cut plants in the direction of a threshing mechanism, and a threshing mechanism, with the aid of which fruits can be removed from the cut plants in such a way that the fruits are then present separately from plant residue of the plants. The feeder comprises a revolvingly driveable conveying unit and a conveyor channel within which the cut plants can be conveyed with the conveying unit. The feeder interacts with a measuring unit in the form of a sensor unit that contactlessly detects material feed height of plants conveyed with the aid of the feeder in the conveyor channel.

  • Publication number: 20190174680
    Abstract: A forage harvester comprising an edge sharpness detection device for detecting a degree of edge sharpness of a cutting mechanism is disclosed. The cutting mechanism comminutes a stream of harvested material, with a material inflow area being defined where the cutting blades interact with the shear bar to comminute the harvested material. The edge sharpness detection device excites one or more magnetic circuits, with the respective magnetic circuit being closed by the respective cutting blade during rotation of the cutter drum once one of the cutting blades passes the magnetic assembly (positioned outside of the material inflow area). The edge sharpness detection device detects the magnetic flux in the respective magnetic circuit and, based on a detected change, determines a degree of edge sharpness of the respective cutting blade. Further, the magnetic flux of the magnetic circuit may be guided lengthwise in the cutting blade at least along a longitudinal section of the respective cutting blade.

  • Patent number: 10292321
    Abstract: An agricultural work machine configured to avoid anomalies is disclosed. Agricultural work machines may encounter anomalies, such as obstacles (e.g., tires) or irregularities in the crop (e.g., weeds), which can reduce the quality of the harvested crop. Manually steering the agricultural work machine requires the constant attention of the vehicle operator. Thus, the agricultural work machine is configured to include sensors to generate one or more images (such as images of various regions of the agricultural work machine), an image processing system to process the images and a control unit to avoid the anomalies (e.g., avoid the identified anomalies, to drive in tracks, and/or to stop the agricultural work machine).

A sensor arrangement for generating surroundings information is provided, and the driver assistance system generates the control actions based on the surroundings information. The sensor arrangement comprises a camera-based sensor system and a laser-based sensor system, each of which generates sensor information regarding a predetermined, relevant surroundings area of the working machine. The sensor information of the camera-based sensor system is present as starting camera images. The starting camera images are segmented into image segments by an image processing system according to a segmentation rule, and the segmented camera images are combined by a sensor fusion module with the sensor information from the laser-based sensor system.
