Abstract
A modular link conveyor including a plurality of modular link assemblies made up of links of an improved design assembled to create a closely interdigitating conveying surface is disclosed. The improved links eliminate undesirable gaps or openings in the conveying surface. Particularly, the improved links include a forwardly extending tongue, projecting from the leading apex of the link, which occupies an open space between the trailing apexes of the legs of the next forward link, thus minimizing the tendency of foreign objects from falling into the open space. The topside of the tongue is tapered downward so as to lift free any objects present in the open spaces primarily while the conveyor is maneuvering through a turn. A forwardly projecting finger, positioned between adjoining links, is also provided for filling a void between the adjoining links. The finger aids in dislodging any foreign objects present in an opening between the legs of the next forward adjoining link, also primarily during turning. Additionally, the legs of the improved links include a trailing apex having an open groove for providing access for inspection and cleaning to the connecting rod that extends throu…
