Patent ID: 7175364

Claim:
An automotive milling machine ( 1 , 11 ) for machining ground surfaces comprising an engine frame ( 2 ), a milling drum ( 8 ) supported on the engine frame ( 2 ), at least one conveying device ( 14 , 18 ) which is arranged on the engine frame ( 2 ) and takes over the milled-off material ( 3 ) from the milling drum ( 8 ) at a first transfer location ( 5 ), a suction device ( 20 ) for air that is polluted with dust and fumes, the at least one conveying device ( 14 , 18 ) for the milled-off material ( 3 ) being enclosed by a duct ( 16 ), the duct ( 16 ) enclosing the conveying device ( 14 , 18 ) being divided into first and second duct sections ( 16 a , 16 b ) with a second transfer location ( 7 ) being located therebetween, the suction device ( 20 ) being connected to the first duct section ( 16 a ) of the duct ( 16 ) downstream from the first transfer location ( 5 ) for the milled-off material ( 3 ), the suction device ( 20 ) sucks off air polluted during milling inside the first duct section ( 16 a ) substantially in the direction in which the milled-off material ( 3 ) is conveyed, and the second duct section ( 16 b ) being separated from the first duct section ( 16 a ) by means ( 36 ) for blocking airflow without hindering the transport of the milled-off material ( 3 ).
