Abstract
In a dust removal apparatus, a front air nozzle unit emits air jets onto a region of a workpiece surface near a rotary brush along a linear front end edge of a hood covering an upper half portion of the rotary brush. Rear air nozzle unit emits air jets onto another region of the workpiece surface near the rotary brush along a linear rear end edge of the hood.
Claims4
A dust removal apparatus comprising:
- a rotary brush disposed substantially parallel to a workpiece surface from which dust particles are to be removed;
- a hood of a generally semi-cylindrical shape covering an upper half portion of said rotary brush, said hood having a pair of opposed side surfaces each having a substantially semicircular shape and linear front and rear end edges;
- an exhaust duct connected to said hood, said rotary brush being moved, along with said hood, relative to the workpiece surface to thereby remove dust particles from the workpiece surface in such a manner that the removed dust particles are directed to said exhaust duct;
- a front air nozzle unit for emitting air jets onto a region of the workpiece surface near said rotary brush along the linear front end edge of said hood;
- and
- a rear air nozzle unit for emitting air jets onto another region of the workpiece surface near said rotary brush along the linear rear end edge of said hood.
