Claims17
A method of mitigating an effect of wind on dispersion of dust created while dumping contents from a truck bed while raising the truck bed to an angle sufficient to facilitate dumping the contents from the truck bed into a material receiving hopper of a truck dumper, comprising:
- enclosing at least a rear portion of the truck bed at least partially in a stilling shed having a roof and sidewalls;
- suspending a first curtain baffle within the stilling shed near the roof such that there is a gap located proximate a junction of a top margin of the curtain baffle and the roof;
- locating the first curtain baffle in the stilling shed such that when the truck bed is raised to the angle sufficient to facilitate the dumping of the contents from the truck bed, the curtain baffle contacts a rear portion of the truck bed;
- and
- exhausting dust laden air from the stilling shed to an air exhaust structure.
