The utility model provides a step type
impact-resistant material guide box which comprises a main support, and a plurality of slide carriages which are transversely and longitudinally arranged in a staggered mode are fixedly arranged on one side of the main support, so that a plurality of cavities are formed in one side of the material guide box. An anchoring part is arranged in each cavity, and the upper portions of the cavities are covered with
metal grid plates. The anchoring part and the
metal grid plate are arranged in the cavity, and the integrally inclined wear-resistant layer is formed by utilizing an integrated pouring structure, so that the structural strength and the
impact resistance of the material guide box are effectively improved; the step part structure is arranged in the middle of the castable layer, a certain amount of sintered ore can be reserved in the early stage of use, lower-layer materials can be fully baked in a high-temperature environment, castable is promoted to gradually reach ideal
sintering strength, large-area abrasion in the early stage and natural falling of the step part in follow-up operation are avoided, a new homogeneous wear-resistant working face is formed, overall abrasion tends to be stable, and the service life of the castable is prolonged. The service life of equipment is prolonged, and the maintenance frequency is reduced.
