Dual-function cargo discharge apparatus

Unloading apparatus for unloading lump material as well as pulverulent material from a hopper having a discharge outlet said unloading apparatus comprising:

• an unloading conveyor positioned in underlying relation to the hopper outlet, a carriage mounted adjacent to the hopper outlet and movable between first and second positions, first gate means associated with said carriage and movable independently thereof for handling lump material, second gate means mounted on said carriage and movable for handling pulverulent material, said first gate means being disposed between the hopper outlet and said unloading conveyor and movable for cooperation with the hopper outlet to control the discharge of lump material therefrom to said unloading conveyor when said carriage is stationary in the first position thereof, said second gate means being disposed between the hopper outlet and said unloading conveyor and movable for cooperation with the hopper outlet to control the discharge of pulverulent material therefrom to said unloading conveyor when said carriage is stationary in the second position thereof, and drive means coupled to said carriage for effecting movement thereof between the first and second positions thereof.

Discharge apparatus for discharge of lump as well as pulverulent material from a hopper having a discharge outlet, said discharge apparatus comprising:

• a carriage mounted adjacent to the hopper outlet and movable between first and second positions, first gate means associated with said carriage for movement independently thereof between open and closed conditions and adapted for handling lump material, second gate means mounted on said carriage for movement between open and closed conditions and adapted for handling pulverulent material, said first gate means being movable for cooperation with the hopper outlet to control the discharge of lump material therefrom when said carriage is stationary in the first position thereof, said second gate means being movable for cooperation with the hopper outlet to control the discharge of pulverulent material therefrom when said carriage is stationary in the second position thereof, gate drive means coupled to said first gate means for effecting movement thereof between the open and closed conditions thereof, and means releaseably coupling said first and second gate means together so that said second gate means moves with said first gate means when coupled thereto and said first gate means moves with respect to said second gate means when decoupled therefrom.
