Description

Technical Field

[0001] The utility model relates to a wear-resistant static jaw plate structure of a jaw crusher, belonging to the technical field of crushers. Background Art

[0002] Jaw crusher is a commonly used crushing equipment, mainly used to crush various ores and rocks with high hardness and compressive strength. There is a pair of jaw plates (also called jaw plates) inside the jaw crusher, which are located in the crushing chamber, and the jaw plate on one side is fixed and called the static jaw plate, and the other side is movable and called the moving jaw plate. When the raw material is fed into the crushing chamber, the moving jaw plate will apply pressure to the fixed jaw plate to crush the raw material, and finally it will be discharged from the discharge port to form the required particle size.

[0003] In the prior art, the static jaw plate generally has teeth bars on its surface that are consistent with the direction of the material falling, which directly contact the material for extrusion and crushing. However, due to the different specifications and shapes of the materials entering the feed port, some areas of the teeth bars are subjected to greater force and are prone to gaps and wear. Once the teeth of the static jaw plate are severely worn, the entire static jaw plate will be unusable and need to be replaced. At the same time, because the direction of the teeth on the static jaw plate is set consistent with the direction of the crusher's falling, it will cause a relatively regular elliptical or spherical material to fall between the static jaw plate and the movable jaw plate. Under the action of the two, it will rotate in the crushing chamber of the crusher for a period of time before being crushed. In severe cases, manual assistance may be required to crush it. Therefore, the utility model proposes a wear-resistant static jaw plate structure of a jaw crusher to solve the above problems. Utility Model Content

During this process, the mounting portion 402 on the bottom plate 401 and the detachably connected tooth block 409 pass through the limiting opening 6 at the same time and emerge from the rack side of the static jaw plate 2. Align the second limiting groove 10 and the first limiting groove 8 at the bottom of the bottom plate 401 and the static jaw plate 2 with the first fixing strip, respectively. The third limiting strip 502 at the top of 501 pushes the bottom plate 401 and the static jaw plate 2 toward the position of the first fixing strip 501, thereby limiting the position of the bottom plate 401 and the static jaw plate 2, and then aligns the third limiting groove 504 at the bottom of the second fixing strip 503 with the first limiting strip 7 and the second limiting strip 9 at the top of the bottom plate 401 and the static jaw plate 2, and finally moves the second fixing strip 503 to one side of the bottom so that the second limiting strip 9 and the first limiting strip 7 completely enter the third limiting groove 504, and then uses the second bolt to connect the second fixing strip 503 to the shell 1 to complete the installation of the bottom plate 401 and the static jaw plate 2.
