When the bauxite piece explodes in this device, the bauxite fragment that produces during the blasting beats on broken tooth 164, and the 8 direction movements of arc apron after the breaker 163 atress, spring 162 compression play the cushioning effect, and when breaker 163 and fore-set 161 contact, spring 162 stops the compression, and the bauxite fragment is broken once more by broken tooth 164, and the broken back spring 162 of bauxite fragment resets, drives breaker 163 and resets to play secondary crushing effect to the bauxite piece.
When the bauxite blocks are blasted in the device, the blasted bauxite blocks generate stronger airflow, the airflow is evacuated through the primary evacuation holes 17, small bauxite blocks are accompanied in the airflow, the small bauxite blocks are left in the anti-gas-break shell 18 through the primary evacuation holes 17, and the rest airflow is evacuated through the secondary evacuation holes 19.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
