[0020] In this embodiment, preferably, snap-fit ​​blocks are installed on both sides of the connecting seat 203, and snap-fit ​​grooves are opened on the opposite sides of the two protective frames 202, with the snap-fit ​​blocks snapping into the snap-fit ​​grooves. This allows for a stable connection between the connecting seat 203 and the protective frame 202, and facilitates disassembly and installation. In specific implementation, the shape and size of the snap-fit ​​blocks and snap-fit ​​grooves are matched to ensure that the snap-fit ​​blocks can be smoothly snapped into the snap-fit ​​grooves, thereby achieving a firm connection between the connecting seat 203 and the protective frame 202. In addition, the materials of the snap-fit ​​blocks and snap-fit ​​grooves are preferably wear-resistant and corrosion-resistant to improve their service life and reliability. By adopting the connection method of snap-fit ​​blocks and snap-fit ​​grooves, not only is the installation and disassembly process of the guide plate mechanism simplified, but its stability and reliability are also improved, facilitating subsequent maintenance and replacement.

[0021] In this embodiment, preferably, a connecting groove is provided on the lower outer side of each protective frame 202, and the connecting block 206 is interference-fitted with the connecting groove. Furthermore, both the connecting block 206 and the connecting groove have concentrically arranged threaded holes, achieving a tight connection between the connecting bolt 207 and the threaded holes through threaded connection. This design further enhances the stability of the connection between the connecting block 206 and the protective frame 202. The connecting groove not only provides accurate positioning for the connecting block 206, but also ensures that the connecting block 206 is not easily loosened or dislodged under stress through the interference fit. Simultaneously, the concentrically arranged threaded hole design allows the connecting bolt 207 to bear force evenly, further improving the reliability and stability of the connection. This structural design not only facilitates installation and disassembly, but also effectively resists vibration and impact during long-term use, extending the service life of the entire guide plate mechanism.

The bearing not only allows the drive wheel 209 to rotate smoothly around the drive shaft of the drive motor 210, reducing frictional resistance and improving the smoothness and stability of transmission, but also effectively distributes the load borne by the drive shaft, extending its service life. Furthermore, the design of the mounting bracket 211 provides stable support for the drive wheel 209, ensuring its stability and reliability during operation. This structural design not only improves the mechanical performance of the entire device but also facilitates installation and disassembly, reduces maintenance costs, and enhances the overall user experience.

[0024] In this embodiment, preferably, the positioning plate 300 has a through groove inside, and the movable plate 204 and the moving plate 208 are movably connected to the positioning plate 300 through the through groove. Each movable plate 204 has a detachable limiting frame 205 on its outer end. The limiting frame 205 further enhances the stability and positioning accuracy of the movable plate 204. Specifically, the limiting frame 205 is connected to the outer end of the movable plate 204 by bolts or other fastening devices, ensuring that the movable plate 204 will not deviate from the predetermined track during movement. Simultaneously, the detachable design of the limiting frame 205 facilitates the maintenance and replacement of the movable plate 204, improving the flexibility and maintainability of the entire device. Furthermore, the through groove design not only achieves a movable connection between the movable plate 204 and the positioning plate 300, but also ensures the stability and accuracy of the movable plate 204 during movement, thereby improving the stability and working efficiency of the entire device. This structural design fully considers the needs of actual use, ensuring the convenience and efficiency of disassembling and installing the coal mill guide plate.

[0025] In this embodiment, preferably, a protective component 600 is configured around the periphery of the coal mill body 100.
