Abstract
A bulk flow belt feeder gate for discharging a bulk material such as mineral ore or the like from a ship hold or the like onto an unloading conveyor belt beneath the ship hold, and a cooperating striker plate positioned immediately contiguous the downstream end of the bulk flow belt feeder gate and interlocked with the gate, whereby the striker plate is automatically selectively movable into an operative or inoperative position in accordance with whether the bulk flow belt feeder gate is in open or closed position. When in a 'down' or operative position corresponding to an open position of the bulk flow belt feeder gate, the striker plate controls the cross-sectional shape of the load of bulk material passing from beneath the associated bulk flow belt feeder gate onto the conveyor belt downstream of the given gate, the striker plate cooperating with the associated bulk flow belt feeder gate to provide what in effect is a material flow metering action which determines the tonnage of bulk material delivered by the belt conveyor per unit time. When in a raised or inoperative position, corresponding to a closed position of the associated bulk flow belt feeder gate, the striker plate is in noninterfering relation with respect to bulk material deposited on the conveyor by another bulk flow belt feeder gate upstream of the given gate.
