Ore screening panel fastener

摘要

A headed retention pin is proposed that seats into recesses in the lower adjoining edges of two screening panels. The heads are tapered vertical from the upper surface of the head to the lower edge of the panels and tapered horizontally from the outer edge of the heads toward the center line of the head which lies on the join line of the two adjacent panels. These appear to be an X in plan view. The advantage is that as well as locating the panels correctly and retaining the panels on the frame they also pull the adjacent panels together to reduce ingress of fines between the panels.

主权项

1. A screening panel and fastener combination in which the fastener is securable to a panel support frame and incorporates a head that fits into recesses in the lower edge of two adjacent screening panels wherein the fastener head varies in cross sectional area in the vertical direction away from the support frame and decreases in width in the horizontal direction from its outer edge toward its centre line, the adjacent panels engaging the fastener head along the centre line to form a line of abutment therebetween, the fastener head exerting a resistance in the horizontal plane to prevent the adjacent panels from moving apart.
