Description

Technical Field

[0001] The utility model relates to the technical field of cone crushers, in particular to a liner used for cone crushers. Background Art

[0002] Cone crusher is a modern high-performance crusher designed and developed based on the principle of laminated crushing and the concept of more crushing and less grinding. It is suitable for crushing various ores and rocks with medium or higher hardness. It has the characteristics of reliable structure, high production efficiency, convenient adjustment, and economic use. One of the main components of cone crusher is the liner, which has the functions of lifting grinding media, grinding ore, and protecting the grinding cylinder. However, since the liner is often subjected to strong impact, it is easy to cause serious wear, which will cause problems such as uneven product particle size, reduced production efficiency, and increased energy consumption. Therefore, it is also very important to select a suitable liner.

[0003] At present, the movable cone liner in the cone crusher is mainly composed of an integrated cone cover. Although the movable cone liner of this structure can realize the extrusion crushing of ore, the surface structure of the movable cone liner of the above structure is relatively flat, so the movable cone liner is prone to wear during use due to the relatively concentrated force on the local surface, thereby reducing the service life of the movable cone liner. At the same time, the movable cone liner needs to be repaired by timely welding after wear. The repair process is relatively cumbersome, which makes the repair efficiency of the movable cone liner relatively low. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is to provide a liner for a cone crusher which can not only increase the service life of the movable cone liner but also perform rapid repair after the movable cone liner is worn, in view of the current status of the prior art.

[0006] (II) Technical solution

[0007] The utility model is realized through the following technical scheme: the utility model proposes a liner for a cone crusher, comprising a pad body, the outer wall of the pad body is evenly distributed with wear-resistant ball tables from top to bottom, a screw groove is opened in the middle of the bottom end of the wear-resistant ball table, a countersunk hole is opened on the pad body opposite to the screw groove, and a countersunk bolt matching the screw groove is installed in the countersunk hole.

[0008] Furthermore, the cushion body is a conical cover-shaped structure, and the cushion body is made of high manganese steel plate.

[0009] By adopting the above technical solution, the cushion body is the main structure of the movable cone liner in the cone crusher.

[0010] Furthermore, an opening one is provided at the top of the cushion body, and an opening two is provided at the middle of the bottom of the cushion body, and the size of the opening two is larger than the size of the opening one.

[0011] By adopting the above technical solution, such a design facilitates the rapid insertion of the cushion body on the main shaft of the cone crusher.

[0012] Furthermore, two mounting holes are symmetrically provided on both sides of the upper end of the pad body, and the mounting holes penetrate the pad body.

[0013] By adopting the above technical solution, the mounting holes cooperate with the external bolts to realize the rapid installation and locking of the cushion body on the cone crusher.

[0014] Furthermore, the wear-resistant ball table is a high manganese steel semi-circular ball, and the bottom end of the wear-resistant ball table is in contact with the surface of the pad body.

[0015] By adopting the above technical solution, in addition to the crushing effect of the pad body on the ore, the wear-resistant ball table can also achieve multi-point contact between the outer side of the pad body and the ore during use through the curved surface structure on the outer wall of the wear-resistant ball table. This design can effectively disperse the force of the ore acting on the outer wall of the pad body during crushing, and avoid local wear of the outer side of the pad body due to long-term high force.

[0016] Furthermore, the countersunk bolt passes through the countersunk hole, and the countersunk bolt is screwed to the screw groove.

[0017] By adopting the above technical solution, when the wear-resistant ball table needs to be replaced and repaired, it is only necessary to remove the corresponding countersunk bolts to achieve the rapid replacement of the corresponding wear-resistant ball table.

[0018] Furthermore, the first opening and the second opening are both formed on the pad body.

[0019] By adopting the above technical solution, the cushion body and the parts on the cone crusher can be conveniently matched and installed.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the movable cone liner in the current cone crusher is mainly composed of an integrated cone cover, although the movable cone liner of this structure can realize the extrusion and crushing of ore, the movable cone liner of the above structure has a relatively flat surface structure, which makes the movable cone liner easy to wear during use due to the relatively concentrated force on the surface, thereby reducing the service life of the movable cone liner. At the same time, the movable cone liner needs to be repaired and welded in time after wear, and the repair and welding process is relatively cumbersome, which makes the repair efficiency of the movable cone liner relatively low. The utility model installs a wear-resistant ball table on the outside of the conical pad body, and uses the wear-resistant ball table to crush the ore, so that the dynamic cone liner can reduce the force of the ore on the surface of the pad body in a multi-point contact manner when in use, thereby improving the wear resistance of the pad body surface and extending the service life of the pad body. At the same time, with the design of the countersunk hole, countersunk bolt and screw groove, the wear-resistant ball table on the surface of the pad body can be replaced and repaired in time after wear, eliminating the tedious operation of repair welding, thereby improving the service life of the dynamic cone pad after wear.
