ABSTRACT:
A materials handling system (30) for controlling the gravity discharge of material through a discharge opening (33) onto a conveyor (34) comprises a gate (40) extending across the discharge opening (33) and having a plurality of outlet openings (40.4) therein for the through flow of material from the discharge opening (33) through the gate (40). The gate (40) has closure members (71) for the outlet openings (40.4). First and second linkage members (71.4, 71.5) extend along the gate (40) and a power source (71.6, 71.7) for moving the linkage members (71.4, 71.5) relative to the gate (40) and independently of each other, is provided. Coupling members (71.8) for selectively coupling the closure members (71) to either one or the other of the linkage members (71.4, 71.5) is provided. In an another embodiment, a feeder deck (60) is provided below the gate (40). The feeder deck (60) has a materials receiving surface (61.5), corresponding with each outlet opening (40.4) in the gate (40). A scraper (61.8) for each materials receiving surface (61.5) is provided for moving material along the surface (61.5) to discharge the material onto the conveyor (34).
