Abstract: The invention relates to a conveyor belt arrangement of a material processing device having a conveyor belt (20) and a receiving and adjustment mechanism for adjusting the conveyor belt between a transport position and a working position. To this end, the conveyor belt is mounted on bearing elements (40, 60), which are rotatably connected to receiving elements (30, 50) of the receiving and adjusting mechanism. According to the invention, the receiving elements are each coupled to a pivot bearing each having a pivot axis (30.1, 50.1) for the pivotable attachment to the material processing device, and at least one bearing element is connected to the conveyor belt in a linearly adjustable manner, and/or between the conveyor belt and the pivot bearing of at least one receiving element, a compensating mechanism is provided, by means of which a spacing change between the bearing elements can be compensated for. The conveyor belt arrangement allows the simple adjustment of the conveyor belt of a material processing device between a working position and a transport position.

Abstract: The invention relates to a rock processing machine (10) having a feed hopper (40) and a process unit (20) downstream thereof, wherein a conveying device, in particular a hopper discharge belt (12), is assigned to the feed hopper (40), wherein the feed hopper (40) has a hopper side wall (42), and wherein a side-wall heightening (44) is assigned to the hopper side wall (42), which side wall heightening can be swiveled between a folded-down working position and a folded transport position. In such a rock processing machine, the requirements of occupational safety are effectively taken into account in a simple manner if provision is made that an operating unit (50) having a lever (51) for swiveling the side-wall heightening (44) is assigned to the side-wall heightening (44), wherein a transmission element (52) is used to couple the lever (51) to the side-wall heightening (44), and that the side-wall heightening (44) is secured in the folded-down working position using a movable locking element (60).
