A set of brushes 13 is fixed to one side of the T-shaped rod 12. During operation, the connecting rod 10 drives the T-shaped rod 12 and the brushes 13 to rotate synchronously. The brushes 13 are made of conductive carbon fiber, which can remove the powder wedged into the sieve holes and dissipate static electricity through conductivity to prevent secondary adsorption of powder. The movement trajectory of the brushes 13 covers the entire inner wall of the screening chamber 4 to ensure no cleaning dead corners.
