[0035] In this embodiment, the construction waste to be screened is poured into the interior of the curved screen 104, and the servo motor 102 and the drive motor 116 are turned on at the same time. The servo motor 102 drives the curved screen 104 to swing through the L-shaped plate 103, so that the curved screen 104 swings inside the curved groove 101 through two limit blocks 117.

The combing plate 108 is movably embedded in the interior of the mounting ring 106 through the connecting rod 107, so that the combing plate 108 will not rotate with the curved screen 104. The combing plate 108 can spread out the construction waste inside the curved screen 104 to prevent the construction waste inside the curved screen 104 from piling up. To reduce the screening effect and efficiency, curved extension plates 105 are fixedly installed on both sides of the curved screen 104.
