[0028] In this embodiment, when construction waste is screened on the sub-screen 4, since some construction waste of different sizes may get stuck on the sub-screen 4, the first motor 12 is started, and the first motor 12 drives the cam 8 to rotate, and the cam 8 drives the T-frame to slide back and forth, so that the T-frame 9 hits the surface of the sub-screen 4, making it easier to screen and fall the construction waste on the sub-screen 4.

[0029] Specifically, refer to Figure 1 and Figure 2 The inner side wall of the box body 1 is rotatably connected with two mutually meshing crushing rollers 13, and the right sides of the two crushing rollers 13 are fixedly connected with gears 14, and the two gears 14 are meshed with each other. The right side of the box body 1 is fixedly connected with a second motor 15 whose output shaft is fixedly connected to the rear gear 14.

[0030] In this embodiment, when construction waste that needs to be crushed is put into the box 1, the second motor 15 is started, the second motor 15 drives the rear gear 14 to rotate, the rear gear 14 drives the front gear 14 to rotate, and the two gears 14 drive the two crushing rollers 13 to rotate to crush the put-in construction waste.

[0031] Specifically, refer to Figure 2 A first inclined plate 16 is fixedly connected to the right inner wall of the box body 1 , and a second inclined plate 17 is fixedly connected to the left inner wall of the box body 1 . The first inclined plate 16 and the second inclined plate 17 are arranged alternately.
