摘要

A sweep arm assembly (30) and cleanout port (54) are provided for a dry bulk materials feeding system (1). A supply hopper (20) having an outlet (23) is disposed above a chamber (50) such that material may flow from the hopper (2 0) to the chamber (50). The chamber (50) has a flat bottom surface (51). A feed trough (60) is disposed below a slot (52) in the bottom surface (51) of the chamber (50) such that material may flow from the chamber (50) to the feed trough (60). A sweep arm (33) is disposed in the chamber (50) and located adjacent to the bottom surface (51). The sweep arm (33) is rotated to "sweep " the material in the chamber (50) to the slot (52) in the bottom surface (51) .
