Abstract
A wear resistant funnel sheet element for a material guide chute includes first and second edges located at a tapered angle from each other. Interlinking fastening features are provided in order to mate the respective edges of at least one of the wear resistant funnel sheets to form a funnel element. The sheet element may be a molded flat piece of a rubber material, which serves as an interchangeable wear part on a material guide chute.
Claims11
A wear resistant funnel sheet element for a material guide chute, comprising:
- a first edge and a second edge, the first edge and the second edge being located oppositely and at a tapered angle to each other;
- and
- a plurality of fastening features located at the first and second edges, the first edge being arranged to mate with the second edge for forming a funnel element from at least one of said wear resistant funnel sheet elements, the plurality of fastening features being a plurality of interlinking connector elements arranged to form a frustoconical or frustopyramid shape funnel element from the at least one of said wear resistant funnel sheet elements, the plurality of interlinking connector elements forming a releasable connection between the first and second edges of either the same wear resistant funnel sheet element or a combination of two or more wear resistant funnel sheet elements, wherein each of the plurality of interlinking connector elements includes a through-hole that align together in combination, the alignable through-holes being arranged such that the through-holes of adjacent interlinking connector elements align to receive a rod element therethrough to form a seam joining the first and second edges, the through-holes including protruding structures arranged to facilitate insertion of the rod.
A method of constructing a funnel element for connection to a holder funnel element in order to form a funnel section for a material guide chute, including the steps of:
- providing at least one wear resistant funnel sheet element having fastening features at a first edge thereof;
- fastening the first edge via the fastening features to a second edge of the same or another funnel sheet element and, by bending about a longitudinal axis, forming the funnel element into a frustoconical or frustopyramid shape, the fastening features being interlinking connectors located at both the first and second edges, wherein each of interlinking connector element includes a through-hole that align together in combination, the through-holes being arranged such that the through-holes of adjacent interlinking connector elements align to receive a rod element therethrough to form a seam joining the first and second edges, the through-holes including protruding structures arranged to facilitate insertion of the rod;
- and
- threading a rod element through the alignable through-holes to fasten the respective first and second edges together, the alignable through-holes including protruding structures arranged to facilitate insertion of the rod element.
