Abstract

1391316 Mining machine DOBSON PARK INDUSTRIES Ltd 22 June 1973 [27 Oct 1972] 49617/72 Heading E1F A mining or excavating machine comprises a mineral working tool 13 mounted as an extensible boom 12 articulated to a carriage 10, a first conveyor means including a ramp 14 which scoops up material mined or excavated by the tool 13 and two conveyors 17 positioned or positionable over and beyond the opposite sides of the ramp for gathering material worked by the tool and conveying it onto a second conveyor 25 extending from front to rear of the machine. The conveyors 17 are pivoted at 18 to a ramp 14 and movable by rams 19 to cover an area in front of the machine, each having blades 23, Fig. 2 carried by a bar 22 reciprocated by rotating cranks 24, or paddles carried by an endless chain. Or there may be two screw conveyors (32) and (33), Fig. 5, pivotally mounted on the ramp 14.
