The dust-laden airflow generated during crushing is conveyed to the filter box 8 through the conveying pipe 10. The dust-laden airflow passes through the filter cylinder 17, which filters the internal dust-laden airflow. The airflow that meets the requirements passes through the support plate 15 and is discharged through the exhaust pipe 12. The dust inside the dust-laden airflow is filtered out and falls onto the upper end of the support plate 15. The filter cylinder 17 can be replaced and repaired later through the maintenance port. After crushing, the cleaning frame 21 can be moved by the push handle 24. The cleaning roller 22 inside the cleaning frame 21 cleans the upper end of the filter screen 2 during movement, preventing the mesh of the filter screen 2 from clogging and facilitating subsequent use of the equipment. By setting up the filtration mechanism 9, the dust-laden airflow generated during crushing can be filtered to prevent the dust-laden airflow from spreading to the outside and affecting the environment, and also to prevent the dust-laden airflow from affecting the health of the operators. By setting up the cleaning component 14, the mesh of the filter screen 2 can be cleaned after crushing, preventing the mesh of the upper end of the filter screen 2 from clogging, which can improve the screening efficiency of the filter screen 2 and facilitate subsequent use of the equipment.
