The drum screen comprises a drum screen entrance section (1) and a drum screen exit section (5) that are connected to each other. A feeding port (2) is installed at an entrance of the drum screen entrance section (1). A screen underflow collection device (7) is disposed below the drum screen. Several screen holes (101) are disposed on circumferential directions of the drum screen entrance section (1) and the drum screen exit section (5). Several bag breaking cutters (102) are installed on a circumferential inner wall of the drum screen entrance section (1), and cutter cleaning devices (103) fitting the bag breaking cutters (102) are disposed in the drum screen entrance section (1). A hole cleaning device (6) for cleaning the screen holes (101) is disposed on peripheries of the drum screen entrance section (1) and the drum screen exit section (5). Several strip object hanging devices (501) are installed on a circumferential inner wall of the drum screen exit section (5), and three rows of hanging needle chains (502, 503, 504) are installed in the drum screen exit section (5).
