Abstract
A deduster is comprised of two sets (pairs) of counter-rotating dedusting brushes in cooperation with a vacuum system for saw dust removal from wooden lumber. In addition to these features, the deduster may feature a separate, movable, top brush assembly that can be easily adjusted for different board thicknesses and raised up to allow for clearing board jams and for pass-through if boards were to be run without dedusting. This deduster apparatus is modular, thereby allowing it to be positioned over an existing machine or a lumber board unscrambler machine such as a lugged unscrambler machine. There is also a deduster for a board handling hopper.
Claims11
A board handling hopper for removal of dust from wood boards comprising
- at least two opposite support walls that form a V-shape comprising a first angled wall and second angled wall which first and second angled walls touch each other and that are adapted to receive and support wood boards in the hopper;
- at least one of the support walls being formed of a plurality of flat panels wherein the flat panels are positioned so that there is a gap between adjacent panels;
- a vacuum port in a plenum with direct connections to the gaps between the panels of the hopper support walls;
- whereby wood dust can be vacuumed from under wood boards that are deposited in the hopper for processing.
A board processing deduster system comprising
- (a) a board handling hopper for removal of dust from wood boards comprising

- at least one of the support walls being formed of a plurality of flat panels wherein the flat panels are positioned so that there is a gap between adjacent panels;
- a vacuum port in a plenum with direct connections to the gaps between the panels of the hopper support walls;
- whereby wood dust can be vacuumed from under wood boards that are deposited in the hopper for processing;
- and
- (b) a wood board processing deduster.
