Open the CIPO recordAbstract From the Canadian patent
The invention relates to a device for a hopper for crushed material. The hopper has a downwardly narrowing portion which leeds to an outlet with arcuate lateral edges, at which outlet a discharge chute is pivotable between a folded-down position for material discharge and a position for preventing discharge. The chute is provided at its opposite lateral edges with a pair of wedge-shaped deflector plates which, as the chute is pivoted, sweep under the arcuate lateral edges to push material away and prevent it from being jammed between the chute and the lateral edges of the hopper.
