Coal feeder with quick release cleanout door

摘要

A suction type coal feeder provided with a rear cleanout opening normally closed by a pivotally mounted cleanout door. A quick release mechanism normally clamps the door in its closed position with this mechanism including a pair of brackets mounted on each side of the housing of the feeder. These brackets are secured in place by the mounting bolts for the feed roll plugs that form a part of the feeder and are located at each end of the feed roll that is mounted at this rear portion of the feeder. Studs extend from these brackets in a rearward direction and a clamp bar is pivotally mounted on one of these studs and extends to the other stud which is received in an upwardly extending slot in the clamp bar. The position of the clamp bar is such that it extends across the upper region of the cleanout door and is effective to clamp the door closed by means of handle nuts threaded onto the studs. Loosening of the nuts permits the pivotal removal of the clamp bar and opening of the cleanout door.
