The invention provides a bale plucker air hood capable of cleaning iron chips. The bale plucker air hood comprises an air hood body, wherein the air hood body is connected with an air ventilation channel; grooves with equal depth are formed in the inner side of an air hood body wall at equal distance; a V-shaped baffle is arranged between the adjacent grooves and is composed of a baffle I and a baffle II; and the grooves are internally provided with strip-shaped magnets. According to the bale plucker air hood capable of cleaning the iron chips, when cotton fibers move towards the air ventilation channel along the inner wall of the air hood body, the iron chips in the cotton fibers are adsorbed in the grooves by the strip-shaped magnets, so that the aim of removing the iron chips is realized; and the device is simple in structure and obvious in cleaning effect.
