DE1956847B2 - BREAKING ROLLER ARRANGEMENT FOR A ROLLER SHEARING MACHINE - Google Patents

Description

it lies in the middle of the face conveyor, crushes the on the side of the entrance opening of the portal slide brought coal and prevents

The invention relates to a brecli roll assembly through stagnation and overflowing the heap a roller shearer that works with a 45.

The gantry slide can be moved on the face conveyor. The deepest point of the

leads and the seam in both directions of travel with the head track of the crushing roller tools approximately in the two levels protruding laterally into the working face, in which the upper edge of the inlet opening cutting rollers is located solves which is located on the swiveling support bracket of the portal slide when the level Men, arranged 50 of the horizontal axis so as to be rotatable about horizontal axes, are the head track of the cutter mill and protrude over both ends of the machine. witness affected. A so sized and adjusted There are roller shearers known which can have two with a breaker roller with normal shearer rollers on one long side of the machine body, in which the cutting roller tools lay the bed Cutting rollers that cut laterally into the mining end, with their tools only those protrude butt, are equipped. Both Schrämwal- 55 capture pieces of debris, which over the upper edge of the zen this lying on a portal slide and protrude entry opening. This will make each The roller comminuting machine, which can be moved above the face conveyor, is cut into the face conveyor are avoided by two to horizontal enclosed coal and the crushing roller is always held housing axes pivotable support arms. only burdened when actually congestion to be-on common housing takes the support arms 60 are afraid.

The horizontal swiveling device used as a bearing is expediently the crushing roller diameter

sen and has between the two swivel knives and the cutting roller diameter so on axis another horizontal axis around which the other coordinated that the crushing roller tools a crushing roller rotates. This crushing roller has only - even in the deepest cutting roller position - not in It's the job of the carriages of the carriers of the face conveyor between the two cutting edges roll into chunks of coal that is breaking in. Collisions between the face conveyor downsizing, the debris discharge with the help of the immittel and the tools of the crushing roller are inter to improve your existing cross conveyor. consequently excluded.
