ABSTRACT:
A bulk material container comprises a discharge opening defined by a discharge assembly. A sliding gate overlays the discharge opening for preventing bulk material to advance through the discharge assembly. The sliding gate is withdrawn from the position overlaying the discharge opening to discharge material from the bulk material container through the discharge assembly into a hopper. A closure seal surrounds the discharge opening. When the sliding gate is disposed over the discharge opening, cam assemblies raise the sliding gate into compressive sealing engagement with the closure seal. When the cam assemblies lower the sliding gate, the sliding gate is withdrawn from the discharge assembly. Wipers mounted on the discharge assembly remain in contact with the sliding gate to remove bulk material that may remain on the sliding gate while the sliding gate is withdrawn from the discharge assembly.
