Bidirectional rack-arranging jaw crusher toothed plate

The utility model relates to a toothed plate with bidirectionally arranged racks for a jaw crusher. The utility model is characterized in that toothed racks in transversal arrangement are arranged on the upper parts of a fixed toothed plate and a movable toothed plate and toothed racks in vertical arrangement are arranged on the lower parts. During operation, the toothed plate with bidirectionally arranged racks can even more effectively nip and timely crush a crushed piece, and the phenomenon that material slides on the toothed plate, blocks a jaw or escape an empty jaw can be avoided. Simultaneously, material granules are uniform and have coincident shape after crushing.
