The materials entering the flat conveying roller 3 are stirred through mutual contrarotation of the two adjacent third spiral pushing wires 31, and the materials are conveyed and transferred to one side of the conveying line. And the materials which do not meet the size requirement fall through the gaps 5 between the lifting rollers 2 or the flat conveying rollers 3, and finally the purposes of material collection and screening are achieved.
