A cone crusher

Abstract

The invention relates to the field of mining equipment, in particular to a cone crusher. The cone crusher comprises a machine frame, 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 machine frame; the eccentric mechanism is connected with the transmission mechanism in a transmission mode, the lower end of the movable cone main shaft set is positioned and installed in the eccentric mechanism, the hydraulic lifting mechanism is located below the movable cone main shaft set, and the hydraulic lifting mechanism and the movable cone main shaft set are connected with each other through the supporting assembly. The eccentric mechanism of the cone crusher is good in dustproof effect and can be fully lubricated.

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 working principle is to drive the rotary motion of the main shaft group of the movable cone through the eccentric mechanism, and the main shaft group of the movable cone and the fixed cone cooperate with each other to crush the stones. The eccentric mechanism of the existing cone crusher includes a bearing seat and an eccentric sleeve. The eccentric sleeve is positioned in the bearing seat through the bearing, and the lower end of the movable cone main shaft group is positioned in the eccentric sleeve through the bearing. Lubrication and dust protection; however, the existing cone crushers have the following two disadvantages: 1. The dustproof effect of the eccentric mechanism is not good, especially when the movable cone spindle group moves axially to adjust the ...

Problems solved by technology

The eccentric mechanism of the existing cone crusher includes a bearing seat and an eccentric sleeve. The eccentric sleeve is positioned in the bearing seat through the bearing, and the lower end of the movable cone main shaft group is positioned in the eccentric sleeve through the bearing. Lubrication and dust protection; however, the existing cone crushers have the following two disadvantages: 1. The dustproof effect of the eccentric mechanism is not good, especially when the movable cone spindle group is moved axially to adjust the size of the crushing cavity, the current There are dust-proof components that cannot be adjusted accordingly, so in the process of adjusting the size of the crushing cavity, the eccentric mechanism is easy to trap dust, which affects the production of the equipment

2. The lubricating channel setting of the cone crusher is unreasonable, resulting in insufficient lubrication of the eccentric mechanism, and prone to spindle lock-up and other phenomena
