Device and method for locating and removing foreign bodies in agricultural machinery

摘要

A conveying device for material to be chopped with conveying rollers comprises a foreign body detection device and a chopper mechanism whose signals are fed to a control device which controls rapid stopping of the conveying rollers when a foreign body detection signal exceeds a predetermined threshold. Upon reversing operation of the conveying rollers, the detection device is used to end the reversing operation when the foreign body is positioned in front of the conveying rollers.
