The dust generated during the mixing of the battery raw materials is filtered through the filter 4. In the process of the pipe shaft 15 rotating, the fixed rod 41 is rotated at the same time, and the ends of the multiple groups of bristles 42 are fitted with the top of the mixing barrel 9. When the bristles 42 rotate to the position of the filter 4, the filter 4 is cleaned to remove the sliding The rod 51 is pushed downward to move the blade 52 downward from the inside of the protective box 5. When the battery raw materials are stirred by multiple sets of stirring blades 16, the blade 52 breaks the raw materials. When the battery raw materials are stirred, the slide rod 51 is pulled upward again to make the blade 52 enter the inside of the protective box 5. When the knocking plate 32 contacts the surface of the fixed block 33 during rotation, the ball 6 rolls on the surface of the fixed block 33.
