ABSTRACT:
A shearing machine with shearing heads or drums rotatably mounted on a luffable shearing arm and a loading ramp or a conveyor running in the direction of the heading face for receiving and conveying away the sheared material. The loading ramp or the conveyor is supported displaceably in the longitudinal direction of the shearing machine on the machine frame and the horizontal luffing axis of the shearing arm runs transversely to the longitudinal direction of the machine and is mounted adjustably relative to the machine frame in the longitudinal direction of the machine. The adjustment movement of the horizontal luffing axis of the shearing arm is coupled to the adjusting movement of the loading ramp or of the conveyor. The shearing arm is mounted on a bearing bracket which is connected to a carriage. The carriage is displaceable on guides running in the longitudinal direction of the machine and the bearing bracket is connected to a driver which is formed by a slot guide. After a predetermined displacement distance of the bearing bracket in the longitudinal direction of the machine, the bearing braket interacts with the conveyor.
