Abstract
A material-conveying apparatus includes an endless belt supported for travel in a path extending around a pair of rollers. A pair of support plates extend beneath the lateral edges of the belt along an upper run of the belt each of the support plates including an opening extending therethrough which permits material passing incidentally between the belt and the support plate to pass to an area beneath the support plate. A pair of deflection plates are disposed beneath the support plates. The deflection plates each include an upper edge which is disposed beneath and between the lateral edges of the upper run of the belt and extend downward and laterally outward relative to the upper run of the belt to a lower edge which is disposed laterally outward of the edges of the belt, whereby the material passing through the openings is directed by the deflection plates to an area laterally displaced from the lower run of the belt. Additionally, or alternatively, a scraper is disposed between the upper and lower runs of the belt and includes a scraper edge which contacts the inwardly directed surface of the endless belt along the lower run. The scraper edge is angled so that material incident…
