Multi-cylinder cone crusher

Abstract

The invention relates to the field of mining equipment and particularly relates to a multi-cylinder cone crusher. The multi-cylinder 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 lower frame and an upper frame, the transmission mechanism, the eccentric mechanism, the moving cone group and the moving cone anti-reverse rotation mechanism are mounted on the lower frame, the transmission mechanism is in transmission and connection with the eccentric mechanism, the lower end of the moving cone group is 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; and the eccentric rotary oscillation of the moving cone group of the multi-cylinder cone crusher is stable.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a multi-cylinder cone crusher. Background technique [0002] The multi-cylinder cone crusher is a kind of mining machinery used for crushing stones. Its principle is to drive the eccentric mechanism to rotate eccentrically through the transmission mechanism, and the eccentric mechanism drives the moving cone group to rotate and swing, and through the mutual cooperation between the moving cone group and the fixed cone frame For crushing stones. However, the existing multi-cylinder cone crusher has the following disadvantages: 1. The lower frame structure of the existing multi-cylinder cone crusher is unreasonable, which leads to inconvenience in the installation of the eccentric mechanism and the transmission mechanism, and is prone to The phenomenon of transmission disengagement; 2. The eccentric mechanism includes the bearing seat and the eccentric bushing, and the eccentric bus...

Problems solved by technology

However, the existing multi-cylinder cone crusher has the following disadvantages: 1. The lower frame structure of the existing multi-cylinder cone crusher is unreasonable, which leads to inconvenience in the installation of the eccentric mechanism and the transmission mechanism, and is prone to The phenomenon of transmission disengagement; 2. The eccentric mechanism includes the bearing seat and the eccentric bushing, and the eccentric bushing is positioned in the bearing seat through the bearing; while the contact between the eccentric bushing and the bearing is offset, the positioning effect is not good, and the bearing misalignment is prone to occur. The phenomenon of damage to the eccentric shaft sleeve; 3. The installation stability of the moving cone group of the cone crusher is insufficient, which is specifically reflected in: the moving cone is set on the moving cone shaft, and the circumferential gap between the moving cone and the moving cone shaft Fixed, prone to deflection and loosening; 4. The connection between the moving cone group and the eccentric mechanism is only to position the lower end of the moving cone shaft in the eccentric sleeve through the bearing. During the swinging process of the moving cone group, the balance of the moving cone group is insufficient. As a result, the swing amplitude of the moving cone group is unstable, the size of the crushed stone particles is different, and the crushing effect is not good; The pendulum direction of the cone group is uncertain, which is prone to material slippage and poor stone crushing effect.
