Description

Technical Field

[0001] The utility model relates to the technical field of crushers, and specifically relates to a gyratory crusher. Background Art

[0002] A gyratory crusher is a large-scale crushing machine that uses the gyratory motion of a crushing cone in the conical cavity of a housing to exert extrusion, splitting, and bending effects on materials, and coarsely crushes ores or rocks of various hardnesses. It is a type of cone crusher and is mainly used for the coarse crushing of ores.

[0003] According to a single-side feeding top hydraulic support gyratory crusher with the patent number CN 108579871B, the moving cone liner is composed of two or three sections. The lower part fits with the conical surface of the body, and the upper part is locked downward by an upper nut. The gap between the moving cone liner and the body is filled with epoxy resin backing glue. There is a locking device above the upper nut to prevent it from backing off the thread. However, the lower space of the crushing cavity formed between the moving cone and the static cone of the gyratory crusher during crushing is small. When the moving cone and the static cone are performing extrusion operations, the lower part of the moving cone liner is subjected to greater force and is extremely prone to wear, greatly reducing its service life. Moreover, the most severely worn part is its lower part. The above-mentioned moving cone liner is an integral body, and replacement requires overall replacement. Therefore, the moving cone liner is improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a gyratory crusher to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A gyratory crusher includes a moving cone liner, which is composed of an upper moving cone liner and a lower moving cone liner. The outer wall of the lower moving cone liner is provided with detachably connected liners distributed annularly. The plurality of detachably connected liners are butted into a conical tube shape, and the lower end of the upper moving cone liner is used for clamping the detachably connected liners.

[0006] Preferably, the outer side wall of the detachably connected liners distributed annularly coincides with the extended conical surface at the lower end of the upper moving cone liner.

[0007] Preferably, the detachably connected liner includes an arc-shaped liner, a lower mounting block, and an upper mounting block. The lower mounting block is mounted at the lower end of the back of the arc-shaped liner and is inserted into a clamping groove opened at the lower end of the lower moving cone liner. The upper mounting block is mounted at the upper end of the back of the arc-shaped liner, and the upper mounting block extends upward and is inserted into a positioning groove opened at the upper end of the lower moving cone liner.

[0008] Preferably, the lower end of the upper moving cone liner is sleeved on the upper end of the lower moving cone liner to limit the upper mounting block, and the bottom surface of the upper moving cone liner is attached to the upper end of the arc-shaped liner.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: A gyratory crusher, by setting the moving cone liner to be separable, the upper moving cone liner limits the detachable liner installed on the surface of the lower moving cone liner. Since the lower end of the moving cone liner wears greatly after long-term use, it is only necessary to replace the detachable liner. The detachable liner can be disassembled by separating the upper moving cone liner from the lower moving cone liner, saving resources, improving production efficiency, and having high economy.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-4 , the present utility model provides a technical solution: A gyratory crusher includes a moving cone liner 1. The moving cone liner 1 is composed of an upper moving cone liner 11 and a lower moving cone liner 12. A ring-shaped distributed detachable liner 2 is installed on the outer wall of the lower moving cone liner 12. A plurality of the detachable liners 2 are butted into a conical cylinder shape, and the lower end of the upper moving cone liner 11 is used for clamping the detachable liner 2.
