Technical Field

[0001] This utility model relates to the field of jaw crusher technology, specifically to a wear compensation device for jaw crushers. Background Technology

[0002] Jaw crushers, also known as jaw breakers or tiger's mouth crushers, consist of a crushing chamber formed by two jaw plates: a moving jaw and a stationary jaw. They simulate the movement of an animal's jaws to crush materials. They are widely used in the crushing of various ores and large materials in industries such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemicals.

[0003] For example, a jaw crusher described in patent document CN221062835U can adjust the crushing size according to the crushing requirements during the crushing process, thereby improving the applicability and flexibility of the crushing process. At the same time, it is easy to collect the dust generated during crushing, thereby improving the cleanliness of the working environment and reducing the harm to the human body.

[0004] However, in the existing jaw crusher, the fixed jaw plate and movable jaw plate have a relatively fixed size of crushed stone blocks, so the size of crushed stone blocks cannot be changed. At the same time, during the operation of the existing jaw crusher, the stone gets stuck in the tooth groove of the jaw plate, which increases the wear of the tooth surface. Therefore, it is necessary to shake the stone out of the tooth groove of the jaw plate to reduce the wear of the tooth surface between the fixed jaw plate and the movable jaw plate.

[0005] Therefore, we need a wear compensation device for jaw crushers to solve the existing wear problem of jaw crushers and reduce the wear on the tooth surfaces between the fixed jaw plate and the movable jaw plate. Utility Model Content
