ABSTRACT:
A new mechanical shovel adapted for mounting on a vehicle and for shovelling continuously onto a conveyor consists of a plurality of buckets pivotally mounted equidistantly around an axis to two spaced coaxial cam disc members rotatable by a drive about an axis. These two rotatable members are mounted between and each closely adjacent to another respective coaxial cam disc member also coaxial with the axis. The first-mentioned rotatable cam members have a plurality of cam tracks each for a respective bucket, while the second-mentioned cam members each have a single endless bucket-attitude determining cam track. Each bucket has cam followers each of which cooperates with two cam tracks, one on each member, so that the buckets pivot to the required attitude for shovelling and subsequent discharging as they are rotated about the axis. The inclination of the shovelling part of the bucket path can be changed by rotating the second-mentioned cam members about the axis.
