摘要：
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.
