cone crusher

Abstract

The invention relates to the field of mining equipment, and in particular relates to a cone type crusher. The cone type crusher comprises a rack, and a transmission mechanism, an eccentric mechanism, a hydraulic hoisting mechanism, a movable cone main shaft set and a supporting assembly which are arranged in the rack, wherein the eccentric mechanism is in transmission connection with the transmission mechanism; the lower end of the movable cone main shaft set is positioned and mounted in the eccentric mechanism; the hydraulic hoisting mechanism comprises a hydraulic cylinder and a piston which is arranged in the hydraulic cylinder and can move in the axial direction; and the piston is connected with the movable cone main shaft set by the supporting assembly. The supporting assembly of the cone type crusher has good stability and can be sufficiently 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 principle is to squeeze and crush stones between the movable cone main shaft group and the fixed cone rotating through the swing. A crushing cavity for crushing stones is formed between the fixed cone liners on the top. In order to crush stones of different particle sizes in the existing cone crusher, a hydraulic lifting mechanism is provided under the moving cone main shaft group, and the hydraulic lifting mechanism is connected with the moving cone main shaft group through the support assembly; through the lifting and lowering of the piston in the hydraulic lifting mechanism, Adjust the axial height of the movable cone main shaft group to change the size of the crushing cavity, and the function of the support assembly is: it can not only axially support the mov...

AI Technical Summary

Problems solved by technology

However, the existing cone crusher has the following two disadvantages: 1. The supporting assembly includes an upper thrust plate fixed on the lower end of the movable cone main shaft group, a lower thrust plate fixed on the upper end surface of the piston, and a The intermediate thrust plate between the upper thrust plate and the lower thrust plate, the upper and lower ends of the intermediate thrust plate are respectively matched with the upper thrust plate and the lower thrust plate; When the swing speed of the main shaft group is too fast, the stop push plate is easy to be separated from the centrifugal force, and there is a potential accident

2. The oil passage lubrication circuit of the existing cone crusher is unreasonable, resulting in insufficient lubrication of the support components, and prone to spindle lock-up and other phenomena
