Full-cavity feeding device of medium and fine crusher

The full-cavity feeding device comprises a shell and a feeding cylinder, the interior of the shell is communicated with the feeding cylinder, a sorting mechanism is installed in the feeding cylinder, lantern rings are fixedly connected to the interior of an inclined plate, the interiors of the two lantern rings are in clearance fit with guide rods, and the guide rods are in clearance fit with the interiors of the guide rods. The top end of the guide rod is fixedly connected with the feeding cylinder, and the bottom end of the guide rod is fixedly connected with a transverse plate. According to the full-cavity feeding device of the medium and fine crushing crusher, through cooperative use of an inclined plate, a lantern ring, a guide rod, a transverse plate, a strong spring and the like, through holes are formed in the inclined plate so that silt can be conveniently filtered out, meanwhile, movement of raw materials is facilitated through movement of the inclined plate, accumulation is prevented, and through c
