Abstract
A pneumatic fumes collection system for an auger-type distributing device that spreads hot asphalt behind a mobile paver includes a rotatable auger shaft extending horizontally above a surface being paved and laterally to a longitudinal centerline axis of the paver. The shaft includes a plurality of auger flights spaced therealong, and can be raised and lowered to a plurality of elevations above the surface being paved. A fumes intake inlet is positioned above, and in a fixed spacial relation to, the auger shaft, whereby the fumes inlet raises and lowers simultaneously with the auger shaft, resulting in an a more uniform fumes collection over a plurality of auger flight elevations. A fumes exhaust fan and exhaust stack are positioned on the paver.
