[0003] Due to the environmental and safety and health disadvantages of manual garbage treatment, bagged garbage began to adopt mechanized processing production lines, such as drum screens. The current working principle of the drum screen is: the garbage enters the rotating drum from the feed port, the bag breaking knife passively cuts the bag, and the garbage is roughly sorted from the screen. Its defects are: First, 2D materials such as strips and films mixed in the garbage are easy to get stuck in the screen, affecting the screening efficiency. At the same time, the screen needs to be frequently cleaned and maintained, affecting the sorting speed; and the material is stuck in the screen for a long time, which is easy to damage the screen, resulting in frequent replacement of the screen; second, the integral screen is adopted, the screen drum is a wearing part and needs to be replaced frequently, and the entire screen drum needs to be replaced, which greatly increases the screening cost. At the same time, the maintenance and replacement time is long, the equipment downtime is long, the productivity is low, the overall screen strength is low, and the damage speed is fast.
