Abstract: A milling rotor includes a drum having a cylindrical wall disposed about a central axis of the drum. The milling rotor also includes a series of milling bit assemblies arranged in a spiral pattern on an outer surface of the cylindrical wall. The series of milling bit assemblies is configured to commence from a lateral plane that is transverse to the central axis of the drum and located partway along a length of the cylindrical wall. The series of milling bit assemblies is also configured to terminate proximate an end of the cylindrical wall. Each milling bit assembly is positioned such that an angle subtended by the series of milling bit assemblies with the lateral plane increases with increasing distance from the end of the cylindrical wall.

Abstract: A cold planer and method for ventilating the cold planer. The cold planer comprises a frame, a hood, a milling drum and a ventilation system. The hood is disposed under the frame and defines a cutting chamber. A milling drum is disposed inside the cutting chamber under the hood. The ventilation system comprises a cutting chamber port, a boost fan, a settling box and a main fan. The cutting chamber port extends through the hood. The boost fan is configured to generate a siphon that draws airflow from inside the cutting chamber through the cutting chamber port. The settling box is configured to cause particles to drop out of airflow. The settling box is in fluid communication with the cutting chamber port. The main fan is configured to draw airflow from the settling box and a region in front of the hood and vent it away from the cold planer.

Abstract: A conveyor system for a machine includes a conveyor belt adapted to convey material from one end to another. A side plate is disposed along an edge of the conveyor belt. A seal having a first edge and a second edge is in contact with the conveyor belt. A pressure applicator is mounted to the side plate. The pressure applicator is adapted to apply a pressure on the seal to maintain the second edge of seal in contact with the conveyor belt.
