Conveyor with metal detector

The utility model discloses a conveyor with a metal detector, which relates to the field of conveyors and comprises a frame and a portal frame, a conveying belt is mounted inside the top of the frame, a protective plate is fixed on the outer surface of the conveying belt, a fence is arranged inside the protective plate, a material cleaning component is arranged inside the fence, and the metal detector is mounted on the portal frame. The material cleaning assembly comprises a damping spring and a material bearing plate. Through the arrangement of the material cleaning assembly, the damping spring can be extruded after the material bearing plate loads mineral aggregate, so that the material bearing plate is lower than the fence, the mineral aggregate cannot be separated and is safer in the transportation process, the mineral aggregate can fall downwards after the fence conveyed by the conveying belt faces downwards, and the damping spring can support the material bearing plate out due to elastic force, so that
