A first conveyor extends in longitudinal direction of the machine frame and has a receiving end which receives bulk material from the clearing device. Immediately trailing the clearing device in the operating direction is a vertically adjustable sweeping device which includes a sweeping broom rotatable about a pivot axis extending horizontal and perpendicular to the longitudinal direction of the machine frame. A second conveyor immediately trails the sweeping device in the longitudinal direction of the machine frame and includes a receiving end for receiving bulk material from the sweeping broom.
