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.
