Problems solved by technology

When in use, the eccentric mechanism, the transmission mechanism and the supporting components all need to be lubricated by the oil passage; however, the oil passage lubrication circuit of the existing cone crusher is unreasonable, resulting in insufficient lubrication of the eccentric mechanism and the supporting components, and prone to main shaft locking.

Abstract

The invention relates to the field of mining equipment, in particular to a cone crusher. The cone crusher comprises a rack, a transmission mechanism, an eccentric mechanism, a hydraulic lifting mechanism, a movable cone main shaft set and a supporting assembly, wherein the transmission mechanism, the eccentric mechanism, the hydraulic lifting mechanism, the movable cone main shaft set and the supporting assembly are arranged in the rack. The eccentric mechanism comprises a bearing pedestal and an eccentric bushing, wherein the bearing pedestal is arranged in the rack, the eccentric bushing is positioned in the bearing pedestal through a bearing, and the lower end of the movable cone main shaft set is positioned in the eccentric bushing through the bearing. The hydraulic lifting mechanism comprises a hydraulic cylinder body and a piston which is arranged in the hydraulic cylinder body in an axial sliding mode, and the piston is connected with the lower end of the movable cone main shaft set through the supporting assembly. A middle lubricating line used for lubricating the eccentric mechanism and a lower lubricating line used for lubricating the supporting assembly are arranged in the cone crusher. After lubricating parts, lubricating oil in the two lubricating lines converges at the lower end of the rack and flows back to an oil supply station through an oil return pipe, so a loop is formed, the eccentric mechanism and the supporting assembly can be circularly lubricated, and the main shaft locking phenomenon can be prevented effectively.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a cone crusher. Background technique [0002] The cone crusher is a kind of mining machinery used for crushing stones. Its principle is to drive the eccentric swing of the movable cone spindle group through the eccentric mechanism, and the cooperation between the movable cone spindle group and the fixed cone is used to crush stones. The main structure of the existing cone crusher includes a transmission mechanism, an eccentric mechanism, a hydraulic lifting mechanism, a moving cone main shaft group and a support assembly. The eccentric mechanism is connected to the transmission mechanism through transmission. The lower part of the movable cone main shaft group is used to change the axial height of the movable cone main shaft group, and the support assembly is used for receiving between the hydraulic lifting mechanism and the movable cone main shaft group. When in use, the eccentr...
