Description

Technical Field

[0001] The utility model relates to the technical field of cone crushers, in particular to a movable cone structure of a cone crusher. Background Art

[0002] Crushing devices are an important component of mining machinery and equipment. They are mainly used to crush the mined minerals for subsequent processing. There are many types of crushing devices. Jaw crushers are usually used for mineral crushing, but their crushing effect is not good. Later, cone crushers were introduced. Cone crushers have become a widely used crushing device in the industry.

[0003] A cone crusher primarily consists of a moving cone and a stationary cone. The moving cone rotates eccentrically under the action of an eccentric sleeve, continuously changing the distance between the moving cone and the stationary cone to squeeze the minerals. Over extended use, the surfaces of the moving and stationary cones gradually wear out. When wear reaches a certain level, they need to be replaced. However, replacing both cones is laborious and extremely costly, comparable to purchasing a new cone crusher. Therefore, to reduce the cost of replacing the moving and stationary cones, existing cone crushers feature wear-resistant bushings on both surfaces. Simply replacing the bushings ensures the normal operation of the cone crusher.

[0004] However, existing wear-resistant bushings are typically connected to the movable and stationary cone bodies using several bolts. However, the internal environment of a cone crusher is relatively harsh during the mineral crushing process. The crushing and extrusion of the minerals can easily deform the exposed bolts, making them difficult to remove and hindering the replacement of the wear-resistant bushings. Therefore, a new movable cone structure for a cone crusher is proposed. Utility Model Content
