A cone crusher

Abstract

The invention relates to the field of mining equipment and particularly relates to a cone crusher. The cone crusher comprises a frame, a transmission mechanism, an eccentric mechanism, a moving cone group and a moving cone anti-reverse rotation mechanism, wherein the frame comprises a bottom frame and a top frame, the transmission mechanism, the eccentric mechanism, the moving cone group and the moving cone anti-reverse rotation mechanism are mounted on the bottom frame, the transmission mechanism is in transmission and connection with the eccentric mechanism, the lower end of the moving cone group is positioned and arranged in the eccentric mechanism, and the upper end of the moving cone anti-reverse rotation mechanism is connected with the lower end of the moving cone group. The top frame in the cone crusher can adjust the axial height of a fixed cone so as to change the size of a crushing cavity; and a fixed cone body in the top frame has high strength and is less liable to damages.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a cone crusher. Background technique [0002] Cone crusher is a kind of mining machinery used for crushing stones. Its principle is to crush stones through the mutual cooperation between the movable cone and the fixed cone that rotates through the swing; the gap between the movable cone and the fixed cone is the cone crusher crushing cavity. However, the existing cone crusher has the following two disadvantages: 1. The top frame of the existing cone crusher can only be used for feeding, and the axial height of the fixed cone cannot be adjusted; therefore, in order to adjust the crushing cavity Size, used to crush stones of different sizes, the existing cone crusher is also equipped with a hydraulic lifting mechanism for changing the axial height of the moving cone group; but under the hydraulic lifting mechanism, the size of the crushing cavity of the cone crusher can be controll...

Problems solved by technology

However, the existing cone crusher has the following two disadvantages: 1. The top frame of the existing cone crusher can only be used for feeding, and the axial height of the fixed cone cannot be adjusted; therefore, in order to adjust the crushing cavity Size, used to crush stones of different sizes, the existing cone crusher is also equipped with a hydraulic lifting mechanism for changing the axial height of the moving cone group; but under the hydraulic lifting mechanism, the size of the crushing cavity of the cone crusher can be controlled accurately The strength is not high, and the maintenance cost of the large hydraulic lifting mechanism is too high; 2, the structure of the fixed cone in the top frame of the existing cone crusher is single, the strength is insufficient, cracks are prone to appear during the crushing process of the cone crusher, and there are potential safety hazards
