Description

Technical Field

[0001] The utility model relates to the technical field of single-cylinder cone crushers, in particular to a lining plate positioning structure of a single-cylinder cone crusher. Background Art

[0002] Cone crusher is a special equipment for material crushing. It is currently widely used in the medium and fine crushing of raw materials in the mining, smelting, building materials, water conservancy and other industries. Cone crusher mainly consists of frame, transmission shaft, eccentric sleeve, hydraulic lubrication and other parts. When the cone crusher is working, the transmission device transmits power to the transmission shaft through the V-belt. The transmission shaft rotates the eccentric device through the meshing of large and small gears. The moving cone rotates and swings under the action of the eccentric device, forming a crushing chamber with the mortar wall fixed on the upper frame. The material is crushed by the swinging extrusion and impact of the moving cone. The fixed cone liner is the main working part of the cone crusher. It is responsible for contacting and crushing the material. Therefore, the fixed structure of the fixed cone liner of the cone crusher is crucial.

[0003] Regarding the positioning of the upper concave liner, currently, Figure 3 As shown, an annular groove is machined on the upper frame 2, and an annular stopper 6 is also machined. The annular stopper 6 is placed between the upper frame and the upper fixed cone liner to play a positioning role. This positioning structure requires the machining of the annular groove and the annular stopper 6. The machining is complicated and requires a large amount of manpower and material resources, which increases the corresponding cost. Utility Model Content
