  • Bucket cleaner and control for a digging machine
    Patent number: 4032015
    Abstract: A cleaning device for attachment to the dipper stick of a backhoe-type excavator. A blade member is slidably affixed to the pivoted end of the dipper stick and can be retracted clear of the path of travel of the backhoe bucket as the bucket is curled and uncurled. The blade member is extensible into engagement with the bottom of the digging bucket so that as the bucket is uncurled, the end of the blade is progressively extended and follows the irregular bottom surface of the bucket, thereby discharging the contents therefrom.
