1. A detection device for detection of a foreign object in an agricultural harvesting machine, the harvesting machine comprising a feed roll assembly with a central shaft and a feed roll rotatably mounted around the central shaft, the central shaft and the feed roll having a common rotational axis, the detection device comprising:
at least one vibration sensor mounted on the central shaft and configured to sense vibrations induced into the feed roll assembly; and a control system operatively coupled to the vibration sensor and configured to:
analyze a signal generated by the vibration sensor anddetermine whether the foreign object has collided with the feed roller therefrom,wherein the vibration sensor is mounted to sense vibrations induced into the feed roll assembly in a direction transverse to the common rotational axis.
