step two: when the materials are crushed, the top of the filter screen (3) is hit in an overlapped mode, so that the second convex block (305) moves upwards in the inner cavity of the second groove, the spring (306) is compressed, the first pull rope (403) and the second pull rope (407) at the bottom are pulled, the filter screen (3) is restored to the original state by utilizing the restoring force of the first pull rope (403) and the second pull rope (407), and the coal which is not crushed is enabled to touch the crushing wheel (202) again for crushing;

step three: when needing to arrange the material, screw out locating pin (606) in proper order, make picture peg (603) break away from with safety cover (602), press filter screen (3) downwards, make lantern ring (303) on first lug (302) use bolt (304) to rotate as the axle center, thereby make filter screen (3) whole slope, insert positioning bolt (605) in the inner chamber of the screw hole of first fixed plate (301), make filter screen (3) rigidity, then make the waste rock material slope discharge to the inner chamber of second case (703) that gathers materials, here simultaneously, make the coal material pass through backing plate (5) and first discharging pipe (6) and get into in the inner chamber of first case (702) that gathers materials.
