Abstract
A hopper apparatus of a type intended for dispensing granular or powdery materials into a conveying system. A container associated with the hopper apparatus has a pair of tapering walls with a discharge opening therebetween. A conveyor loading chamber below the discharge opening and adjacent one of the container walls is in communication with a conveying system. A screen is pivotally mounted to and extends along one of the tapering walls. The screen also overlies the conveyor loading chamber to prevent foreign matter from entering the conveyor. A projection connected to the screen lies slightly in the path of movement of the conveyor to thereby vibrate the screen. A plate mechanism disposed between the discharge opening and the conveyor loading chamber is spaced sufficiently from the wall and screen to allow the powdery or granular matter to pss by, but close enough to the wall such that it will trap larger foreign objects and hold such foreign objects out of the main flow path.
