Cone crusher structure

Abstract

The invention discloses a cone crusher structure which comprises a shell arranged in an inverted cone shape, and an upper crushing wall arranged on the upper part of the shell, wherein a lower crushing wall arranged in an inverted cone shape is arranged below the upper crushing wall; an eccentric shaft which drives the lower crushing wall to eccentrically rotate is arranged in the shell; the distance between the upper crushing wall and the lower crushing wall is decreased progressively from top to bottom; the wall thickness of the upper crushing wall is progressively increased from top to bottom; and the wall thickness of the lower part of the lower crushing wall is decreased progressively from the middle to the upper and lower sides. According to the cone crusher structure, due to treatment of the thicknesses of the upper crushing wall and the lower crushing wall, the wall thickness is increased at the position with the highest working frequency on each crushing wall, and the service life of the crusher can be effectively prolonged. Moreover, the easily damaged crushing walls are movably connected with one another, the crusher is convenient to replace after being damaged, and the cone crusher structure disclosed by the invention is applied to the field of crushing devices.

Description

Technical field [0001] The invention relates to the field of stone crushing devices, and in particular to a cone crusher structure. Background technique [0002] The cone crusher is equipped with a lower crushing wall that rotates eccentrically around the shaft in the shell, and a fixed cover is set on the upper crushing wall to buckle the upper crushing wall on the lower crushing wall. The eccentric shaft drives the eccentric rotation of the lower crushing wall and the inner side of the upper crushing wall. The stones are used to break the stones. [0003] In the past, the lower crushing wall of the cone crusher was integrated, and the thickness of the crushing wall was consistent and uniform. After long-term use of the crusher, it is easy to cause serious damage to a certain part of the crushing wall and cause the crushing efficiency of the machine to drop, and the bottom The replacement and maintenance of the broken wall are quite troublesome. Summary of the invention [0004] ...
