Travelling hopper belt car
First Claim
1. A travelling hopper belt car comprising a superstructure, a belt carrier mounted for pivoting in a vertical plane around a horizontal axis on said superstructure, a throw-off belt mounted for movement in a conveying direction on said belt carrier, a feed chute connected to said belt carrier adjacent said horizontal axis, said feed chute having side walls which each include a lower section fixed to said carrier and an upper side section pivotally mounted to each lower section respectively about a further horizontal axis for folding down at least to a vertical height of said further horizontal axis, said travelling superstructure being mounted for pivoting in a horizontal plane about a vertical axis, a support arm mounted on said superstructure and carrying said horizontal axis of said belt carrier, said support arm extending to a feed end of said throw-off belt under said feed chute, a feed device mounted on said superstructure at opposite sides of said feed chutes, and feed device mounting means for moving said feed device on each side of said feed chute toward and away from said feed chute in a horizontal direction, each feed device comprising a feed trough for receiving material and a bearing connected to each feed trough for pivoting each feed trough about at least one axis which is on one side of said feed end of said throw-off belt and extends in the conveying direction of said throw-off belt.

Abstract
A travelling hopper belt car has a feed chute and a throw-off conveyor belt that can pivot in a vertical plane around a horizontal axis in the area of the feed chute. The side walls of the feed chute are designed in two parts with the upper side section in each case foldable down around a horizontal axis at least to the height of the axis.

12. A travelling hopper belt car comprising a belt carrier pivotally mounted about a horizontal axis for pivoting in a vertical plane, a throw-off conveyor belt movably mounted on said belt carrier for movement in a conveying direction;
- a feed chute connected to said belt carrier adjacent said horizontal axis, said feed chute having side walls which each include a lower section fixed to said belt carrier and an upper side section pivotally mounted to each lower section respectively about a further horizontal axis for folding down at least to a vertical height of said further horizontal axis, a travelling superstructure, said belt carrier being pivotally mounted about said horizontal axis to said travelling superstructure, said travelling superstructure being mounted for pivoting in a horizontal plane about a vertical axis, a support arm mounted on said superstructure and carrying said horizontal axis of said belt carrier, said support arm extending to a feed end of said throw-off belt under said feed chute, height adjustable supporting feed connected to said support arm at said feed end for raising and lowering said support arm at said feet and, a feed device mounted on said superstructure at opposite sides of said feed chute and at said feed end of said throw-off belt, and feed device mounting means for moving said feed device on each side of said feed chute toward and away from said feed chute, each feed device comprising a feed trough for receiving material and a bearing connected to each feed trough for pivoting each feed trough about at least one axis which is on one side of said throw-off belt and extends in a direction of movement of said throw-off belt, a cantilever arm mounted to each feed device, each feed trough being pivotally mounted to one of said cantilever arms for pivoting over said feed chute, a hydraulic cylinder connected between each feed device and its feed trough for pivoting the feed troughs, each feed trough having a leading edge in the direction of its pivoting toward said feed chute which lies in the vicinity of an upper edge of one side wall of said feed chute with said feed trough in its highest point of pivoting over said feed chute, and a grizzly screen pivotally mounted on each feed trough about a pivot axis on a side of each feed trough spaced away from said throw-off belt for pivoting said grizzly sreens away from said feed chute.
