Novel high-strength wear-resistant feed opening

The utility model discloses a novel high-strength wear-resistant feed opening. The utility model belongs to the technical field of mining machinery feed openings. The device comprises a side plate andan inner protective plate, the plurality of side plates are encircled to form a feed opening with an upper opening and a lower opening; a plurality of inner protective plates with one side free edgesinclining upwards or downwards are arranged on the surfaces of the inner walls of the side plates, the other side edges of the inner protective plates are fixedly connected with the surfaces of the inner walls of the side plates, the inner protective plates are transversely arranged, and the two ends of each inner protective plate extend and are fixedly connected with the surfaces, making contactwith the inner walls of the side plates, of the inner protective plates. According to the utility model, the impact and abrasion of ores to the feed opening are effectively reduced, and the service life of the feed opening is
