The utility model relates to the technical field of cotton, and discloses a cotton impurity removing mechanism which comprises a rack, a downward and inward concave groove is formed in the top of the rack, a plurality of screening assemblies are arranged in the groove of the rack from top to bottom, a driving device is further arranged on the wall face of the rack, and the driving device rotates to push an impurity receiving hopper to do reciprocating motion to screen impurities. Two bent plates are symmetrically arranged on the top face of the screening hopper, cover plates are hinged to the wall faces of the two bent plates, an air blower is arranged on the outer wall face of the rack, the bent plates can guide air blown out by the air blower to the top of the screening hopper, the two cover plates form a shielding barrier above the bent plates, and pressure difference is generated through air flowing speed difference. Air pressure supports cotton upwards, impurities in the cotton are heavier than the cotto
