[0002] Jaw crushers are widely used in the crushing of various ores and bulk materials in industries such as mining and smelting, building materials, roads, railways, water conservancy and chemicals. The working parts include a fixed jaw and a movable jaw. The fixed jaw is fixed vertically or slightly outwardly at the upper end on the front wall of the machine body. The movable jaw is tilted to form a crushing chamber with a larger top and a smaller bottom with the fixed jaw. Driven by the eccentric shaft (main shaft), the movable jaw performs periodic reciprocating motion relative to the fixed jaw, sometimes separating and sometimes approaching, simulating the movement of the two jaws of an animal to complete the material crushing operation. The movable jaw is installed on the eccentric shaft and driven by the eccentric shaft. The eccentric shaft is the main shaft of the jaw crusher. However, the fixed jaw in the prior art is completely fixed, and the opening size of the crushing chamber cannot be adjusted according to the size of the ore, which limits the space for the jaw crusher to play and results in the failure to improve the crushing efficiency of the crusher.
