Dust collecting device

摘要

A dust collector device (10) receives dust (72), conveyed in the airflovv F into a diffuser (70) and out through a diffuser mouth (74) wherein it is spayed into the upper regions of an internal space (62) and settles under gravity by falling down the sides of the internal space (62) along settling pathway G. As more dust (72) is blown out through the mouth (74), the dust settles into the tray (20) in a fairly even spread of dust (76). Once the tray (20) is full of settled dust (76), a dust separator device (80) may be switched off whereby the bag (50) naturally deflates due to termination of the inflating pressure created by a transverse blower (88). The bag (50) may be folded and/or tied down about or over bars (64) ready for transport of the dust (76).
