Description

Technical Field

[0001] This utility model relates to crusher components, and more particularly to a moving cone for high-efficiency crushing. Background Technology

[0002] A cone crusher is a device that uses a cone-shaped crushing chamber and a movable cone to crush materials. It is widely used in mining, construction, chemical and other industries, and is mainly used for medium and fine crushing of ores and rocks of various hardnesses.

[0003] A cone crusher consists of a moving cone and a fixed cone. The moving cone is a movable part, mounted inside the frame via a main shaft, and rotates and oscillates driven by an eccentric bushing. The fixed cone is fixed to the upper part of the frame, forming a crushing chamber with the moving cone. Currently, both the moving and fixed cones are typically lined with wear-resistant materials such as high-manganese steel, and these liners are replaceable. The moving cone liner disclosed in the following patent applications with application numbers CN201511024497.1, CN201510607673.8, and CN201410851049.8 all have a toothless structure. This is because the moving cone liner rotates with the main shaft. During rotation, the distance between it and the fixed cone is adjusted to squeeze the ore for crushing. If a horizontal rack is set, it will affect the feeding. If a vertical rack is set, it will increase the resistance to rotation. Moreover, the rack will occupy the distance between the moving cone and the fixed cone, thereby reducing the thickness of the moving cone liner. This will affect the structural strength of the moving cone liner. Although a smooth surface can ensure strength and smooth material passage, it can only rely on squeezing to crush the ore and does not have a cutting effect, resulting in relatively low crushing efficiency. Utility Model Content

[0004] Due to the limitations of existing cone crushers in terms of structure and crushing principle, which restrict them to compression and result in poor cutting performance and low crushing efficiency, this utility model provides a moving cone crusher with high efficiency.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] The high-efficiency crushing moving cone includes a moving cone body and a moving cone liner fitted on the outer wall of the moving cone body. The outer wall of the moving cone liner is a curved surface with an outer diameter that first increases and then decreases from top to bottom. The inner wall of the moving cone liner and the outer wall of the moving cone hammer body are two fitting frustum-shaped surfaces. The outer surface of the moving cone liner is provided with a number of groove groups to increase the crushing and cutting effect. The same groove group includes at most a first groove, a second groove, a third groove, and a fourth groove that are separate and of the same length. When the moving cone liner is unfolded into a plane, the first groove is parallel to the third groove, the second groove is parallel to the fourth groove, and the first groove, the second groove, the third groove, and the fourth groove are located on the four sides of the same parallelogram.

[0007] Preferably, the outer diameter of the moving cone liner is taken as the boundary, and the decrease in outer diameter gradually decreases towards both sides of the boundary.

[0008] Preferably, adjacent groove groups share some grooves, so that the parallelogram containing the same groove group and the parallelogram containing the surrounding groove groups form a mesh structure.

[0009] Preferably, after the moving cone liner is unfolded into a plane, the first groove and the second groove are symmetrically arranged about the vertical direction.

[0010] Preferably, after the moving cone liner is unfolded into a plane, the included angle between the first groove and the second groove is 30-60 degrees.

[0011] Preferably, the moving cone liner and the moving cone body are provided with a keyway and a key that cooperate with each other for circumferential positioning; the top of the moving cone liner is provided with an annular pressing seat, and the bottom of the pressing seat and the top of the moving cone liner are provided with mutually abutting inclined surfaces, and the pressing seat presses the top of the moving cone liner to vertically limit the moving cone liner.

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0020] This embodiment mainly describes the title of the high-efficiency crushing moving cone, as follows:

[0021] High-efficiency crushing moving cone, such as Figure 1-3 As shown, the device includes a movable cone body 20 and a movable cone liner 10 fitted onto the outer wall of the movable cone body 20. The outer wall of the movable cone liner 10 is a curved surface with an outer diameter that increases first and then decreases from top to bottom. The inner wall of the movable cone liner 10 and the outer wall of the movable cone hammer body are two fitting frustum-shaped surfaces. The outer surface of the movable cone liner 10 is provided with a plurality of groove groups 100 for increasing the crushing and cutting effect. Each groove group 100 includes at most a first groove 1001, a second groove 1002, a third groove 1003, and a fourth groove 1004 that are separate and of the same length. When the movable cone liner 10 is unfolded into a plane, the first groove 1001 is parallel to the third groove 1003, the second groove 1002 is parallel to the fourth groove 1004, and the first groove 1001, the second groove 1002, the third groove 1003, and the fourth groove 1004 are located on the four sides of the same parallelogram. This solution involves creating a groove group 100 on the surface of the moving cone liner 10. The groove group 100 includes four separate grooves. Because the grooves are separate structures, the thickness of the liner does not need to be reduced. Furthermore, by creating the grooves, compared to directly using a rack, the thickness of the moving cone liner 10 is reduced while maintaining its thickness and strength. This represents a compromise between the thickness, strength, and crushing performance of the moving cone liner 10. Each groove's edge can form a cutting edge, providing a certain cutting effect during rotation. Through the dual action of cutting and compression, the crushing efficiency of the ore is improved. In actual production, the groove depth can be reduced, and the moving cone liner 10 can be replaced when surface wear is severe. The moving cone liner 10 works in conjunction with the fixed cone 50 to compress the ore. The extrusion is carried out on the area of ​​the moving cone liner 10 excluding the first groove 1001, the second groove 1002, the third groove 1003 and the fourth groove 1004, mainly the area enclosed by the first groove 1001, the second groove 1002, the third groove 1003 and the fourth groove 1004.

[0022] Preferably, the outer diameter of the moving cone liner 10 is taken as the boundary, and the decrease in outer diameter towards both sides gradually decreases. Compared to directly setting its surface as a frustum shape, this structure has a progressively increasing compression amplitude, so that the degree of crushing gradually increases from top to bottom until it falls to its maximum.

[0023] Preferably, adjacent groove groups 100 share some grooves, so that the parallelogram containing the same groove group 100 and the parallelogram containing the surrounding groove groups 100 form a mesh structure.

[0024] Preferably, after the moving cone liner 10 is unfolded into a plane, the first groove 1001 and the second groove 1002 are symmetrically arranged about the vertical direction.

[0025] Preferably, after the moving cone liner 10 is unfolded into a plane, the included angle between the first groove 1001 and the second groove 1002 is 30-60 degrees. Within this angle range, the resistance during rotation can be reduced.

[0026] Preferably, the moving cone liner 10 and the moving cone body 20 are provided with a keyway and a key that cooperate with each other for circumferential positioning; the top of the moving cone liner 10 is provided with an annular pressing seat 30, and the bottom of the pressing seat 30 and the top of the moving cone liner 10 are provided with mutually abutting inclined surfaces, and the pressing seat 30 presses the top of the moving cone liner 10 to vertically limit the moving cone liner 10.

[0027] The moving cone 20 has a mounting hole in the middle, the main shaft 60 passes through the mounting hole and extends out, the moving cone 20 is sleeved and fixed on the main shaft 60, and the moving cone 20 is pressed by the passive cone liner 10. The top of the main shaft 60 is provided with a support structure 40 for the main shaft 60 to extend into, and bearings are provided between the support structure 40 and the clamping seat 30 and between the support structure 40 and the main shaft 60.

Specific examples have been used to illustrate the principles and implementation methods of the present utility model. The description of the above embodiments is only for the purpose of helping to understand the present utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to the present utility model without departing from the principles of the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
