[0025] like Figure 1-Figure 5 As shown, the outer side of the roller 4 abuts against the inner wall of the guide groove 5, and a through hole for filtering is opened on the sorting plate 2, so that the sorting plate 2 can move along the guide groove 5 through the roller 4, separate the coal gangue with smaller diameter during the movement, and drive the unseparated coal gangue to continue to move.

[0026] like Figure 2 and Figure 5 As shown, a power mechanism 7 is installed at one end of the sorting plate 2. The power mechanism 7 includes a cylinder 701 and a piston rod 702, which facilitates the movement of the sorting plate 2 by the power mechanism 7.
