Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a shaft end avoidance protection structure of a double-toothed roller crusher. Background Art

[0002] Double-roll crushers typically feature a dual-roll crushing mechanism consisting of a movable crushing roller and a fixed crushing roller to accommodate different stone sizes. In existing technology, the movable bearing housing supporting the movable crushing roller typically requires a guide plate to mate with the machine body. This guide plate is typically bolted to the machine body to provide guidance when the movable crushing roller vibrates or moves.

[0003] In actual use, if stones enter the crusher through the edge of the double rollers, the dynamic crushing roller will be twisted instantaneously. At the moment of twisting, the dynamic shaft and the dynamic bearing seat will be deflected at a certain angle. If the stones are large, the guide plate will be twisted due to the excessive instantaneous deflection angle of the dynamic bearing seat, causing the fixing bolts of the guide plate to break, and then causing the guide plate to fall off. Since the crushing roller and dynamic shaft of the crusher are heavy, when reinstalling the fallen guide plate, the dynamic crushing roller needs to be lifted and installed in position. In addition, the space around the crusher installation location is usually small, which makes it difficult to install and fix the guide plate. Utility Model Content
