The invention provides a self-feeding crusher based on ore classification. The self-feeding crusher comprises a crusher body; a feeding hole and a discharge hole are respectively formed in the upper part and the lower part of the crusher body; the self-feeding crusher is characterized by further comprising a material shovel hinged on the crusher body; the material shovel comprises a big lifting arm, a hopper and a flexible material spading plate; the big lifting arm is hinged with the crusher body and is provided with a groove; the hopper is a U-shaped structure plate; an opening end of the hopper is hinged with the end, far away from the crusher body, of the big lifting arm; a pouring hole and a material spading hole are respectively formed at the upper side and the lower side of the hopper; the bottom of the hopper is provided with a trench communicated with the groove; the material spading plate is installed in the groove in a sliding way. According to the self-feeding crusher basedon ore classification, ores are fixed by using the closed end of the hopper, are then scooped up by using the material spading plate and are sealed in the hopper, thus being prevented from sliding onthe ground and being conveniently shoveled up.
