Abstract
A dust suppressor apparatus for use in discharging particulate or granular material, such as grain, which includes a housing defining an internal chamber and having an inlet opening in the upper region of the chamber and a discharge opening in the lower region of the chamber. A suppressor control gate is hingedly mounted on the housing and is biased to a position preventing discharge of material through the discharge opening until a predetermined quantity of particulate material acts on the control gate to overcome the biasing and open the control gate. The control gate and is operative to exert pressure on the particulate material discharging through the discharge opening so as to enable bulk discharge while preventing egress of dust ladened air through the discharge opening. Baffle plates are provided in the chamber to reduce grain velocity within the device. The baffle plates may be independently adjustable or may be automatically adjusted upon tilting of the apparatus. A bypass opening is selectively operable to enable passage of material through the dust suppressor so as to bypass the discharge opening and facilitate transfer to a location spaced from the dust suppressor apparatus.
