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).
