In the following detailed description, for the convenience of explanation, many specific details are elaborated to provide a comprehensive understanding of the embodiments of the present utility model. However, one or more embodiments can also be implemented by those skilled in the art without these specific details.

[0022] Such as Figures 1 - 4As shown in the figure, a cone crusher facilitating the replacement of a moving cone liner includes a frame 1. Inside the frame 1, there is a cross-shaped support 2. In the center of the support 2, there is a fixedly connected mounting column 3. The mounting column 3 is integrally formed with the support 2. At the top of the mounting column 3, there is a mounting groove 4. At the bottom of the mounting groove 4, there is a through hole 5. Inside the mounting groove 4, a crushing shaft 7 is provided through a set of first bearings 6. The crushing shaft 7 includes an upper shaft portion 8 and a lower shaft portion 9. On the lower shaft portion 9, there is a bearing mounting portion 10. The set of first bearings 6 is mounted on the bearing mounting portion 10. On the upper shaft portion 8, a moving cone 12 is rotatably connected through a set of second bearings 11. At the bottom of the outer wall of the moving cone 12, there is an annular bottom plate 13. On one side of the top of the annular bottom plate 13 away from the moving cone 12, there is an annular baffle 14. Around the outside of the moving cone 12, there are several moving cone liner blocks 15. The adjacent surfaces of two adjacent moving cone liner blocks 15 are in contact. At the bottom of the moving cone liner block 15, there is an arc-shaped limiting plate 16. The arc-shaped limiting plate 16 is located between the annular baffle 14 and the moving cone 12. The bottom of the moving cone liner block 15 is in contact with the top of the annular baffle 14. On the right side of the top of the moving cone liner block 15, there is a fixedly connected sector block 17. At the top of the moving cone 12, there is a flat surface 18. The sector block 17 is in contact with the flat surface 18. At the top of the sector block 17, there is a counterbore 19. At the corresponding position of the top of the flat surface 18 with respect to the counterbore 19, there is a threaded hole 20. Inside the counterbore 19, there is a fixing bolt 21. The fixing bolt 21 is threadedly connected with the threaded hole 20. The several moving cone liner blocks 15 surrounding the outside of the moving cone 12 are threadedly connected with the threaded holes 20 on the flat surface 18 at the top of the moving cone 12 by using the fixing bolts 21 through the sector blocks 17, thus forming the moving cone liner 22 of the moving cone 12.

[0023] In the above technical solution, the moving cone liner 22 is formed by combining a plurality of moving cone liner blocks 15 surrounding the outside of the moving cone 12 through the way that the sector blocks 17 are threadedly connected with the threaded holes 20 on the flat surface 18 at the top of the moving cone 12 by using the fixing bolts 21. When a certain part of the moving cone liner 22 is severely worn and affects the crushing effect of the crusher, the moving cone liner blocks 15 can be replaced for the worn part of the moving cone liner 22. Compared with the traditional overall replacement of the moving cone liner 22, it saves costs.

[0024] In the present utility model, the bottom end of the lower shaft portion 9 passes through the through hole 5. On the part of the lower shaft portion 9 passing through the through hole 5, there is a transmission wheel mounting portion 23. On the transmission wheel mounting portion 23, there is a transmission wheel body 24 mounted.

[0025] In the above technical solution, by providing a transmission wheel, the transmission wheel can be driven to rotate by an external motor (not shown in the present utility model), and then drive the moving cone 12 and the moving cone liner 22 thereon to rotate, so as to crush the materials falling into the crushing cavity 28.

[0026] In the present utility model, the lower shaft portion 9 and the upper shaft portion 8 of the crushing shaft 7 are fixedly connected through a connecting portion 25. There is a certain eccentricity between the central axes of the upper shaft portion 8 and the connecting portion 25.

[0027] In the above technical solution, by setting a certain eccentricity between the connecting portion 25 of the crushing shaft 7 and the central axis of the upper shaft portion 8, the moving cone 12 can perform eccentric rotation relative to the moving cone 12 when the crushing shaft 7 rotates, thereby facilitating the crushing of the material.

[0028] In the present utility model, a fixed cone 26 is detachably connected to the top of the frame 1. The fixed cone 26 is sleeved outside the moving cone 12 and the moving cone liner 22. A fixed cone liner 27 is provided inside the fixed cone 26. The space between the fixed cone liner 27 and the moving cone liner 22 forms a crushing chamber 28.

[0029] In the above technical solution, by providing the crushing chamber 28 between the moving cone liner 22 and the fixed cone liner 27, while providing conditions for the crushing of the material, it is convenient for the crushed material to fall.

[0030] In the present utility model, an annular support plate 29 is provided at the bottom outside the fixed cone liner 27. The support plate 29 is clamped between the frame 1 and the fixed cone 26. A limit bolt 30 is threadedly connected to the fixed cone 26. The limit bolt 30 is threadedly connected to the support plate 29 while being threadedly connected to the fixed cone 26.

[0031] In the above technical solution, by threadedly connecting the limit bolt 30 to the fixed cone 26 and at the same time the limit bolt 30 is threadedly connected to the support plate 29, it is convenient to fix the position of the fixed cone liner 27 to prevent it from rotating and affecting the crushing quality of the material.

[0032] The working principle of a cone crusher of the present utility model that is convenient for replacing the moving cone liner is as follows:

[0033] During use, the external motor rotates to drive the crushing shaft 7 to rotate. The crushing shaft 7 rotates to drive the moving cone 12 and the moving cone liner 22 on the moving cone 12 to rotate. When the moving cone 12 and the moving cone liner 22 on the moving cone 12 rotate, when the material falls into the crushing chamber 28, the material is driven to roll and crush between the moving cone liner 22 and the fixed cone liner 27, thereby realizing the crushing of the material.

[0034] When the cone crusher has been used for too long and a certain part of the moving cone liner 22 is worn, when it is necessary to replace the moving cone block 15 at the corresponding position, unscrew the fixing bolt 21 in the threaded hole 20 and pull out the fixing thread from the counterbore 19, then the disassembly of the moving cone liner 22 can be completed. After replacing the moving cone block 15 at the corresponding worn position, it is not necessary to replace the entire moving cone liner 22. Compared with the traditional method of replacing the entire moving cone liner 22, it saves more cost.

[0035] In this article, specific examples are used to elaborate on the principle and implementation of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
