A bulk material conveyor belt system comprises a belt, a skirt, and a wear liner. The belt forms a continuous loop having an upper transfer run and a lower return run. The belt defines a theoretical, vertically oriented, center plane about which the belt is generally symmetric. The skirt has a lower edge that extends above the transfer run. The wear liner is removably attached to the skirt in a manner such that the skirt lies between the wear liner and the center plane. The wear liner has a lower edge that that extends above the transfer run and beneath the lower edge of the skirt.

FIG. 1 is a schematic representation of a bulk material conveyor belt system.
FIG. 2 is a perspective view of portion of a skirt of a bulk material conveyor belt system having a wear liner attached thereto in accordance with the invention.
FIG. 3 is an elevation view of a cross-section of a bulk material conveyor belt system in accordance with the invention, as viewed looking along the runs of the conveyor belt.
Reference numerals in the written specification and in the drawing figures indicate corresponding items.
A bulk material conveyor belt system is shown schematically in FIG. 1. The bulk material conveyor belt system 20 comprises a belt 22 that is driven about rollers 24 and forms a continuous loop. The upper portion of the continuous loop is referred to herein as the transfer run 26 and the lower portion of the continuous loop is referred to herein as the return run 28. Preferably, the belt 22 has a trough-like shape (not shown) as it passes along the transfer run 26, but may also be flat. The belt may also have a flat or inverted trough-like shape along the return run 28.
FIGS. 2 and 3 depict a skirt 30 and wear liner 32 assembly. FIG. 3 depicts a cross-section of the settling region of the loading zone of a conveyor belt system 34. Preferably a skirt 30 is positioned on each opposite side of the center plane near each of the edges of the belt 22. Each skirt 30 extends downward and preferably has a lower edge 36 that is positioned above the belt 22 by an amount that is greater than the anticipated height of the bulk material 38 at that location. This prevents the bulk material 38 from abrading the skirts 30. The conveyor belt system 34 may also comprise a cover 40 connecting the top of the skirts 30 to prevent dust from escaping. The skirts 30 are preferably formed steel and may be supported by the frame (not shown) of the conveyor belt system 34, which also supports the components that support the belt 22. As shown in FIG. 2, brackets 42 are preferably welded along the outer surface 44 of each skirt 30 adjacent the lower edge 36 of the skirt. Each bracket 42 protrudes from the outer surface 44 of the skirt 30 and comprises a vertically oriented through hole 46. Additionally, a plurality of threaded studs 48 protrude outward from the outer surface 44 of the skirt 30.
