Claims

[Scope of Claim for Utility Model Registration] (1) In a tooth plate of a crusher that has a wave-shaped crushing surface and a number of cutting edges made of another wear-resistant material are implanted on the surface, A large number of circular holes are drilled toward the circular hole, and the cutting edge that fits into the circular hole has a top portion that is a copy of the original fractured part cut out by the circular hole, and the circular hole and the insertion part of the inserted cutting edge. A tooth plate of a crusher characterized by having a mutually fitting relationship in which the teeth rotate and lock. (2) In claim 1, an arc-shaped protrusion protrudes within the circular hole, and the insertion portion of the cutting edge has a neck portion with the same diameter as the protrusion surface, and a bottom portion with an arc-shaped protrusion having the same diameter as the inner diameter of the circular hole. A tooth plate of a crusher characterized by having protruding ridges. (3) At least one along the circular hole in claim 1.
The vertical groove of the strip is carved vertically, and the vertical groove communicates with the horizontal groove carved horizontally in the circular hole, while the insertion part of the cutting edge consists of a neck with the same diameter as the circular hole, and A tooth plate for a crusher, characterized in that a side surface is provided with at least one protrusion at the depth of the communication point, the protrusion having a horizontal section that fits in the vertical groove and a vertical section that fits in the lateral groove. (4) At least one protrusion protrudes into the circular hole drilled in claim 1, and the cutting edge has a vertical groove on its outer peripheral surface into which the horizontal cross section of the protrusion fits, and a horizontal groove into which the vertical cross section fits. A tooth plate of a crusher, characterized in that the tooth plate communicates at a position that matches the position of the protrusion.
