Earth working machine having a dust extraction system and rotatable filter cartridges

A mobile earth working machine (10), for example a road milling machine, recycler, or surface miner, includes:a working apparatus (12) for material-removing working of a region of a substrate (U); andan extraction device (40) that is embodied to extract dust-laden air from at least one machine region at at least one extraction location (46), and to exhaust extracted air at a discharge location (50) different from the extraction location (46),the extraction device (40) comprising a filter apparatus (42) arranged along an operational flow path from the at least one extraction location (46) to the discharge location (50), the filter apparatus (42) encompassing:a filter housing (54);a filter element (52) received in the filter housing (54), the filter element (52) being embodied to remove dust particles from the air flowing through the filter apparatus (42); anda cleaning apparatus (76) that is embodied to remove from the filter element (52) dust particles that accumulate on the filter element (52) during filtering operation. Provision is made that the filter element (52) is received in the filter housing (54) rotatably around a rotation axis (D), the filter apparatus (42) comprising a rotary drive system (70) that is embodied to impart rotation to the filter element (50).
