The bottom of the fixed cone liner 312 is in contact with the retaining ring 305 on the side away from the lower cone 301, the bottom of the fixed cone liner 312 is in contact with the interior of the lower cone 301 on the side close to the lower cone 301, the top of the fixed cone liner 312 is in contact with one end of the arc baffle 310 on the side away from the connecting portion 302, and the top of the fixed cone liner 312 is in contact with the inner wall of the connecting portion 302 on the side close to the connecting portion 302.

[0026] In the above technical solution, a fixed cone liner 312 is arranged between the annular platform 304 on the inner side of the lower cone 301 and the arc block 308 on the inner side of the connecting part 302 connected by threads, and multiple fixed cones 3 are integrated to form the fixed cone 3 liner of the entire crusher, so that when the crusher removes the fixed cone 3 liner, it is only necessary to loosen the bolt 314 to achieve the fixed cone 3 liner of the crusher from the top opening of the upper cone 303 of the fixed cone 3 for replacement, thereby making the replacement of the fixed cone 3 liner of the crusher more convenient. At the same time, when a certain part of the fixed cone 3 liner is severely worn, it is only necessary to replace the fixed cone liner 312 at the corresponding position, and there is no need to replace the entire fixed cone 3 liner like a traditional crusher, thereby reducing loss and saving costs. By utilizing the cooperation between the first and second protrusions and the groove 313 on the fixed cone liner 312, combined with the blocking of the fixed cone liner 312 by the annular retaining ring 305 and the arc baffle 310, the position of the fixed cone liner 312 can be limited, which is convenient for crushing materials.

[0027] In the utility model, a mounting column 4 is provided in the center of the bracket 2, a mounting groove 5 is provided at the top of the mounting column 4, and a through hole 6 is provided at the bottom of the mounting groove 5.

[0028] In the above technical solution, by setting a transmission wheel 9, the rotation of the transmission wheel 9 can drive the crushing shaft 8 to rotate, and the eccentricity between the central axis of the upper part and the lower part of the crushing shaft 8 is utilized, so that the dynamic cone 11 can move correspondingly relative to the fixed cone 3, thereby generating a force on the material and crushing the material.

[0029] The working principle of the cone crusher which is convenient for replacing the fixed cone lining plate of the utility model is as follows:

[0030] When in use, the transmission wheel 9 rotates driven by the external motor, and then drives the crushing shaft 8 to rotate in the mounting groove 5 of the mounting column 4 with the cooperation of a group of first bearings 7. The rotation of the crushing shaft 8 drives the movable cone 11 to rotate. When the movable cone 11 rotates, due to a certain eccentricity between the central axis of the upper part and the lower part of the crushing shaft 8, the movable cone 11 can move accordingly relative to the fixed cone 3, thereby generating a force on the material and crushing the material.

[0031] When the crusher has been used for too long and the fixed cone liner 312 is worn and needs to be replaced, it is only necessary to unscrew the threaded connection between the bolt 314 inside the countersunk hole 307 and the threaded hole 309, and the fixed cone 3 liner of the crusher can be taken out from the top opening of the upper cone portion 303 of the fixed cone 3 for replacement, thereby making it more convenient to replace the fixed cone 3 liner of the crusher. At the same time, when a certain part of the fixed cone 3 liner is severely worn, it is only necessary to replace the fixed cone liner 312 at the corresponding position, without the need to replace the entire fixed cone 3 liner like a traditional crusher, thereby reducing wear and tear and saving costs.
