When the sorting material identification and detection frame 7 identifies the gangue, the telescopic end of the cylinder 203 can be controlled to extend upward through the external control module. At this time, the guide plate 202 can be pressed down to receive the gangue, and the gangue can be guided to the space in front of the partition 4 inside the box 3, so that the gangue and coal in the gangue can be sorted.
