Description

New hydraulic gyratory crusher motor cone

technical field

The utility model relates to the technical field of hydraulic gyratory crusher accessories, and in particular provides a novel hydraulic gyratory crusher motor cone.

Background technique

In the prior art, the upper and lower bushings of the hydraulic gyratory crushing cone are made of ZGMn13. The length of the upper bushing is 1700 mm, and the length of the lower bushing is 1300 mm. Surface contact for positioning and fixing.

The feeding size of the hydraulic gyratory crusher is below 1200 mm. The original design of the upper and lower bushings of the hydraulic gyratory crusher cone is 1700 mm long, and the length of the lower bushing is 1300 mm. The fitting joint of the upper and lower bushings is exactly 700 mm. Below the ore crushing zone, and the proportion of ore below 700 mm is more than 85%, so most of the materials are crushed in the convex and concave area between the upper and lower bushings, and the convex and concave surface between the upper and lower bushings. It is often broken by the impact of materials, resulting in the sinking of the upper and lower bushings, which makes the crusher stop for maintenance and replacement of the upper and lower bushings of the moving cone. The service life of the upper and lower bushings is generally less than 1000 hours under heavy load.

Utility model content

In order to solve the above technical problems, the utility model provides a new type of hydraulic gyratory crushing motor cone. By modifying the outer dimensions of the upper and lower bushes and the assembly form of the upper and lower bushes, the lower bushing is completely crushed under 800mm particle size. With the position, more than 85% of the ore processing capacity of the hydraulic gyratory crusher is crushed by the lower bushing, which saves the use of the upper bushing and reduces the consumption of the moving cone.

The utility model is achieved by providing a new type of hydraulic gyratory crusher motor cone, which is sleeved on the eccentric shaft of the hydraulic gyratory crusher, and the eccentric shaft drives the movable cone to move to crush large rocks in the crushing cavity of the hydraulic gyratory crusher. , The new hydraulic gyratory crusher motor cone includes an upper bush and a lower bush assembled together. In the crushing chamber, the cavity from the connection of the upper bush and the lower bush is the crushing area for ore with a particle size below 800mm.

Further, the assembly method of the upper bush and the lower bush is taper fit.

Further, the height of the taper matching area of the upper bush and the lower bush is 50-60mm.

Further, the height of the upper bush is 1300-1500mm, and the height of the lower bush is 1500-1700mm.

Further, the height of the upper bush is 1400mm, and the height of the lower bush is 1600mm.

Furthermore, the above-mentioned new hydraulic gyratory crusher cone is applied to the PX1400/170 hydraulic gyratory crusher.

Compared with the prior art, the utility model has the advantages of:

1. By improving the connection between the upper bushing and the lower bushing of the moving cone, the loss of the ore to the connection is reduced, and the service life of the moving cone is extended;

2. By changing the connection mode of the upper and lower bushings of the movable cone, the installation and maintenance of the upper and lower bushes of the hydraulic gyratory crusher are facilitated. The previous installation of the upper and lower bushes without a positioning base point becomes a standard horizontal base point for installation. , Improve the maintenance quality.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Fig. 1 is a structural schematic diagram of the utility model installed on an eccentric shaft;

Fig. 2 is a schematic diagram of the structure of the upper bush and the lower bush before installation of the utility model.

detailed description

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

In order to reduce the impact damage of the crushed ore on the connection between the upper bushing and the lower bushing of the hydraulic gyratory crusher cone, prolong the service life of the movable cone and facilitate maintenance, the utility model provides a new type of hydraulic gyratory crusher cone, refer to Figure 1, The movable cone is sleeved on the eccentric shaft 3 of the hydraulic gyratory crusher, and the eccentric shaft 3 drives the movable cone to move to crush the large rocks in the crushing cavity of the hydraulic gyratory crusher. The new hydraulic gyratory crusher motor cone includes assembled The upper bushing 1 and the lower bushing 2, in the crushing cavity, the cavity downward from the joint of the upper bushing 1 and the lower bushing 2 is the crushing area for ore with a particle size below 800mm.

When the utility model is used for ore crushing, the maximum particle size of the ore is 1200mm, and the ore with a particle size below 800mm accounts for more than 85% of the total ore, so more than 85% of the ore is squeezed and vibrated by the movement of the lower bushing. Crushing, greatly reducing the damage to the connection between the upper and lower bushings when the ore is crushed.

In order to facilitate the assembly of the movable cone and reduce the difficulty of maintenance, the most technical improvement is that the assembly method of the upper bush and the lower bush is taper fit.

Preferably, the height of the taper matching area of the upper bush and the lower bush is 50-60mm.

Preferably, the height of the upper bushing of the movable cone is 1300-1500mm, and the height of the lower bushing is 1500-1700mm.

Further preferably, the height of the upper bush is 1400mm, and the height of the lower bush is 1600mm.

The new hydraulic gyratory crusher cone provided by the utility model can be applied to any matching hydraulic gyratory crusher, preferably applied to the PX1400/170 hydraulic gyratory crusher, so that the service life of the upper and lower bushings can be increased to more than 2000 hours under heavy load , The annual consumption of upper and lower bushing spare parts can be saved by half, which greatly reduces the maintenance of the crusher and reduces the production cost.
