A multi-cylinder hydraulic rolling cone crusher is a mining machinery generally used to crush large rock into smaller rock or gravel. During operation, the main shaft of the movable cone set is driven by the eccentric shaft to make eccentric rotation around the center of the cone, however, the interface between the eccentric shaft and the movable cone is lubricated, and no device for limiting the rotation direction of the movable cone assembly is provided. In some cases, reversal of the direction of rotation of the movable cone may cause the bearing element to slip on the adjacent surface. This sliding action may lead to premature wear of the bearing elements or permanent damage of the bushing. According to the prior experience, the phenomenon that the material slips in the crushing cavity is caused by the anticlockwise rotation of the movable cone, so that ore discharging particles are large, the production efficiency is reduced, and the energy waste is large.

The movable cone anti-reverse rotation mechanism is used for limiting the movable cone group to directionally rotate and preventing materials from slipping.
On the basis, the applicant proposes an adjustable movable cone assembly in Chinese patent publication No. CN116213006A, which comprises a base, an eccentric sleeve movably arranged in the base, a main shaft with a lower end part movably arranged in the eccentric sleeve, and a movable cone body fastened on the upper end part of the main shaft; when the eccentric sleeve rotates, the movable cone body is directly or indirectly driven to swing circumferentially; the lifting driving component is arranged on the base, a supporting component is arranged on the upper end face of the lifting driving component, and the lower end of the movable cone body is in rolling or sliding bearing on the supporting component; the lifting driving part can drive the movable cone body and the main shaft connected with the movable cone body to move up and down.
