The utility model changes the original cylinder initial cleaning structure, and installs a screw feeding device inside the screen cylinder. When the material enters the feeding port, under the action of the spiral blade, the material enters the inside of the screen cylinder evenly, and the rotating Under the action of the screen cylinder, the materials with qualified particle size are discharged through the discharge port, and the large impurities are discharged out of the machine through the action of the guide vanes inside the screen cylinder. Under the action of the filter, the purpose of screening and impurity removal is achieved, and the problem that the screened material of the initial cleaning screen of the cylinder is easy to be blocked in the feed chute and inside the screen drum is solved. It has good adaptability to the screening of different types of materials and improves the screening efficiency.
