The ore enters the receiving piece through the conveyor belt and then falls to the material guide piece. After being buffered and dispersed by the material guide piece, the ore is detected by the first detector and the second detector in turn, thereby avoiding missed detection of ore and facilitating use.

The material receiving piece comprises a hollow cylindrical portion, and the cylindrical portion is connected to the first material feeding port of the first truncated cone wall.

The material guide member comprises a cone portion and a plurality of flow dividers, a part of the cone portion is arranged inside the first truncated cone wall, and the plurality of flow dividers are evenly arranged on the outer wall of the cone portion along the circumference of the cone portion.

The conical portion is coaxially arranged with the first frustum wall, and the radius of the conical portion gradually increases along the return axis direction of the first frustum wall.
