Multi-shaft driven spiral classifier

The spiral classifier comprises a base, a plurality of supporting blocks are fixedly installed at the top end of the base at equal intervals, buffer mechanisms are fixedly installed at the top ends ofthe multiple supporting blocks, a fixing frame is fixedly installed at the top ends of the multiple buffer mechanisms, and spiral rods are connected to the two sides of the inner wall of the fixing frame in a penetrating mode through embedded bearings. And gears are fixedly mounted at one ends of the two screw rods. The spiral classifier has a good buffering effect through the installed bufferingmechanism, in the working process of the classifier, shaking of the fixing frame is reduced through the buffering mechanism, stable work of the spiral classifier is guaranteed, the two sides of the fixing frame are limited through the installed limiting mechanism, the limiting plate is driven to ascend and descend through ascending and descending of the pushing block, and therefore the spiral classifier can stably work.
