Description

Technical Field

[0001] The utility model relates to the field of mine crushers, in particular to a mine crusher. Background Art

[0002] Crusher is a pulverizing machine used in the processing of metal and non-metallic ores. It can crush the mined raw ore into small particles by squeezing and bending. It uses external force to break large pieces of material into small pieces, providing raw materials with particle sizes that meet process requirements for subsequent processes and facilitating storage and transportation.

[0003] For example, a mining crusher disclosed in the utility model with authorization announcement number CN219519038U includes a main body, a power mechanism arranged on the side of the main body, a plate hammer arranged on the inner side of the main body, a rotor arranged inside the main body, and an impact plate arranged inside the main body. The main body is composed of an upper machine base and a lower machine base. The designed limiting mechanism is used to improve the problem that when the upper machine base and the lower machine base need to be assembled during the use of the original crusher in the mine, there is a certain inconvenience in the alignment operation of the mounting holes between the two during the assembly process. By setting limiters on both sides of the connection between the upper machine base and the lower machine base The mechanism can confirm the alignment of multiple mounting holes between the upper and lower machine bases by means of snap-fitting during the assembly process. When the multiple mounting holes are aligned, the upper and lower machine bases are automatically limited by the limiting mechanism, and then the subsequent bolt penetration operation is performed, thereby increasing the convenience of crusher assembly. When the device crushes stones, the power mechanism drives the internal rotor to rotate at high speed, so that the plate hammers on the rotor hit the stones to complete the crushing. After being hit by the plate hammers, the materials are thrown to the impact plate for secondary crushing. The crushed materials collide with each other at high speed and are crushed again, but it is difficult to control the specifications of stone crushing. Utility Model Content
