The invention relates to a conveyor belt arrangement of a material processing device having a conveyor belt () 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 (), which are rotatably connected to receiving elements () 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 () 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.

Conveyor belt arrangement of a material processing device

A belt tensioning device for a crusher or a screening machine for tensioning at least one circulating drive belt which is deflected about a belt pulley of a drive and has a load strand and an empty strand. The drive can be driven with a crushing assembly, a screening unit, a generator, or the like of the crusher by the drive belt. The vibrational stress acting on the machine chassis can be significantly reduced in that the belt tensioning device has two tensioning rollers each of which is rotatably mounted on a holder of a tensioning part. One tensioning roller is paired with the empty strand and the other is paired with the load strand. Additionally, the two tensioning parts can be adjusted relative to each other between an open position and a tensioning position, in which the tensioning parts are held against each other at least opposite the tensioning direction. In particular the tensioning parts can be blocked against each other, and the complete closed system can be freely moved linearly using adjustment guides according to the load situation.
