[0038] In the present embodiment, the limestone crushing and grinding equipment is provided with a fixing rod, a slot 7, a sliding rod 11, a dovetail tenon 8, a dovetail groove 12 and a fixing bolt. When in use, the breaker 13 rotates to collide with the limestone. After a long period of use, the breaker 13 is worn when colliding with the limestone. After wear, the crushing efficiency will be reduced and it needs to be replaced. When replacement is needed, the first fixing bolt 9 is removed and the sliding rod 11 is pulled out of the slot 7 to complete the disassembly. The dovetail groove 12 inside the sliding rod 11 at the bottom end of the new breaker 13 is aligned with the dovetail tenon 8 inside the slot 7, and the sliding rod 11 is inserted into the fixing rod, and fixed by the first fixing bolt 9 to complete the installation, so that the breaker 13 can be easily replaced, and the stability of the structure is enhanced by the reinforcing ribs 6 on the fixed column 5, so that the crushing and grinding process is more stable.

[0039] It should be noted that the motor 22 drives the first driving pulley 23 and the second driving pulley 24 to rotate at the same time.

[0040] The working principle of the above embodiment is:

[0041] First, start the motor 22. The motor 22 starts to run, and its output end drives the first driving pulley 23 and the second driving pulley 24 to rotate. The first driving pulley 23 drives the first driven pulley 18 to rotate through the first belt 25, thereby causing the first rotating shaft 4 and the fixed column 5 and the crushing hammer 13 thereon to start rotating. As the first rotating shaft 4 rotates, the crushing hammer 13 fixed thereon also starts to rotate and collides with the limestone entering the crushing area, thereby crushing it. The sieve hole 29 at the bottom end of the lower shell 3 allows limestone of the appropriate size to pass through and be discharged from the bottom of the equipment. During the whole process, the cover 21 prevents the rocks generated during crushing from flying out, ensuring safe operation. At the same time, the two baffles 30 ensure that the crushed limestone can accurately fall on the conveying device 26 to prevent it from being scattered.

[0042] Among them, as the use time increases, the breaker hammer 13 may be worn due to collision. When it is worn to a certain extent, the crushing efficiency will be reduced and it can be replaced. First, loosen the nut 10, release the fixation of the first fixing bolt 9 on the slide rod 11, pull the slide rod 11 out of the slot 7, complete the disassembly, install the new breaker hammer 13 and slide rod 11 on the fixed column 5 in the original way, and fix them with the first fixing bolt 9 and nut 10 to complete the replacement.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
