Chain driven cutting bucket for use in deep mining

Patent ·
OSTI ID:6542840

A bucket is disclosed for both chipping coal from a coal seam and for removing the coal from the seam. The bucket is arranged for flexible coupling to preceding and succeeding buckets to form a continuous train for rotation through a coal tunnel. Along the side of each bucket there is mounted a cutting blade for dislodging the coal. A ramp on the side of the bucket serves to scoop the dislodged coal into the bucket. When the bucket emerges from the mine tunnel the bottom of the bucket falls away and the coal is unloaded directly into waiting hoppers.
