ABSTRACT:
An improved enclosed belt conveyor system for transferring material with a minimum of dust and energy consumption. An alignment device having an external adjustment mechanism to adjust dynamically balanced spools, which are mounted on a shaft is terminated in the alignment devices. The belts for the conveyed material are in an enclosed structure while the bearings and the bearing adjustment mechanisms are external of the enclosed structure, which encloses the spools and the belts thereby limiting the debris or dust to which bearings are subjected. The balanced flared spools have closed and sealed ends, thereby totally eliminating air turbulence, within the structure. Turbulence will accentuate dust movement within the enclosure. This invention permits the alignment of each individual roller while maintaining the cones of the spools and bearings in a dust free environment as possible. The spool cone is not subjected to a fan-like effect at the ends of the spool creating air turbulence and depositing material in the cone. The bearings if contained within the enclosed structure are subjected to any and all dust or debris which came from the material due to the turbulence in prior art of the fan-like effect of the spool. There is also a plug or release door in the tail with separately driven poodles for dislodging and removing accumulated material from the enclosure. There is no balanced spindle or spool with closed ends mounted to an exterior alignment device for the bearing similar to this invention. The special compartmentalized structure, including the trapezoidal shape roof or top, sheds water and permits easy access to the interior of the structure.
