  • System and method for managing speed of cold planer conveyor belt
    Patent number: 10308440
    Abstract: A system and method for determining and controlling a speed of a conveyor belt configured for transferring material from a source of the material to a haul vehicle includes a motor and associated head pulley shaft operatively coupled to a conveyor belt head pulley configured for driving the conveyor belt. The motor is connected to a conveyor belt tensioner block configured to enable adjustment of a tension in the conveyor belt, and the head pulley shaft is rotatably supported within the conveyor belt tensioner block. A speed ring gear is mounted on the head pulley shaft and located at least partially within a bore through the conveyor belt tensioner block. A speed sensor is mounted on the conveyor belt tensioner block in a position radially outward from teeth of the speed ring gear as the speed ring gear and head pulley shaft rotate within the bore through the belt tensioner block.
