A hydraulic cone crusher

Abstract

The invention relates to the field of mining equipment, in particular to a hydraulic cone crusher. A hydraulic cone crusher, comprising a machine base, a drive motor and a frame arranged on the machine base, and a transmission mechanism, an eccentric mechanism, a hydraulic lifting mechanism, a moving cone main shaft group and a supporting assembly arranged in the frame; The drive motor drives the eccentric mechanism through the transmission mechanism, the lower end of the movable cone main shaft group is positioned and installed in the eccentric mechanism, the hydraulic lifting mechanism is located below the movable cone main shaft group, and the hydraulic lifting mechanism and the movable cone main shaft group are connected through a support assembly; The cone crusher has high strength, good stability and easy installation.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a hydraulic cone crusher. Background technique [0002] Cone crusher is a kind of mining machinery used for crushing stone. Its main components include the frame, and the transmission mechanism, eccentric mechanism, hydraulic lifting mechanism, moving cone main shaft group and support assembly arranged in the frame; among them, the eccentric mechanism Connected with the transmission mechanism, the lower end of the movable cone spindle group is positioned and installed in the eccentric mechanism, and the eccentric mechanism drives the movable cone spindle group to rotate and swing; the hydraulic lifting mechanism is located under the movable cone spindle group of the cone crusher to adjust the movable cone spindle The axial height of the group can change the size of the crushing chamber; the support assembly is arranged between the hydraulic lifting mechanism and the movable cone s...

Problems solved by technology

[0003] However, the existing cone crushers have the following disadvantages: 1. At present, the cone crushers are only equipped with a load-bearing frame base, but not equipped with a motor seat for installing a driving motor. When using a machine, a table will be built on one side of the frame base, and the drive motor will be installed on the table, which is very inconvenient for the installation process; 2. The feed inlet and outlet of the existing rack are relatively small, resulting in The stone flow rate of the cone crusher is not large, which affects the production efficiency of the equipment; 3. The eccentric sleeve in the eccentric mechanism is not stable enough, and it is easy to shift axially, and the eccentric bush in the eccentric sleeve is rigidly connected to it, resulting in the eccentric bush and The wear between the movable cone spindle groups is relatively large, which reduces the service life of the equipment; 4. The connection strength of the movable cone spindle groups is not enough, and the movable cone liner is easy to loosen, posing a safety hazard; 5. The hydraulic oil sealing effect in the hydraulic lifting mechanism Poor, and the piston gland used to position the oil seal is easy to fall off when the equipment is running, posing a safety hazard; 6. The stability of the support assembly is insufficient. When the swing speed of the movable cone main shaft group is too fast, the stop push plate is easy to be centrifugally separated. There is a risk of accident
