EARTH WORKING MACHINE HAVING A DUST EXTRACTION SYSTEM WITH SELECTABLE FILTRATION OF THE EXTRACTED DUST-LADEN AIR
A self-propelled 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 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); anda 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).The filter apparatus (42) comprises a bypass valve (60) shiftable between two different operating positions, such that a filtering operating position connects the at least one extraction location (46) to the exhaust location (50) with passage through the filter element (52); and a bypass operating position connects the at least one extraction location (46) to the exhaust location (50) while bypassing the filter element (52).
