Abstract
Components for wear-resistant surfacing helical metal conveyor blades have segments of wear-resistant material of like shape conforming to the helix curvature for mounting in side-by-side relation on a face of the blade. The segments have at least one slot which extends through their inner end and diagonally across the segment toward its outer end. A bar is provided for insertion in each groove with its end projecting from the inner end of the groove, the projecting bar ends being welded to the blade face to prevent movement of the segments relative to the blade.
Claims7
Components for wear-resistant surfacing helical metal conveyor blades comprising:
- a segment of wear-resistant surfacing material adapted for attachment in side-by-side relation with other like segments to a face of said blade to form a conveying portion thereof, said segment having a widthwise and radially outer end curvature conforming to that of the helix and diminishing in width from its outer end toward its inner end;
- said segment having therein at least one groove extending through the inner end thereof and diagonally across the segment toward the outer end thereof;
- and a bar of weldable metal for each said groove slidably fitting in the groove and of sufficient length to provide an end portion protruding from the inner end of said segment for welding to a face of said stub blade;
- each said groove and bar having a complementary shape such as to prevent relative movement thereof in directions other than axially of said groove.
