Abstract
A crustbreaking assembly comprising elongated rails supported on a frame and a carriage moveable along the length of the rails. A slide assembly pivotally mounted on the carriage for rotation about an axis which is substantially parallel to the rails. A hammer assembly mounted on the slide assembly with a longitudinal axis substantially perpendicular to the rails and including a reciprocable cutting bit which reciprocates along the longitudinal axis of the hammer assembly.
Claims20
A crustbreaking assembly for use in aluminum fusion electrolysis cells comprising:
- a plurality of rails extending along a first axis;
- a frame supporting said rails;
- a carriage adapted to engage and be moveable along said plurality of rails in a direction substantially parallel to said first axis;
- a slide assembly;
- rotation means for said slide assembly pivotally mounting said slide assembly to said carriage for pivotally movement of said slide assembly about a second axis which is spaced from and substantially parallel to said first axis;
- a hammer assembly having a longitudinal axis which is substantially perpendicular to said first and second axes;
- means for mounting said hammer assembly on said slide assembly;
- and
- means for reciprocating said hammer assembly in a rectilinear manner along said hammer assembly longitudinal axis.
