This utility model relates to the technical field of hopper equipment, specifically a hopper safety device with lifting and protective functions. It includes a hopper body, a movable baffle body on the top outer side of the hopper body, a large lifting ring on the top side of the hopper body, and a small lifting ring on the top side of the movable baffle body. The outer wall of the hopper body and the outer wall of the movable baffle body are connected by a lifting component. The lifting component includes a guide cylinder and a guide rod that slide against each other. The guide cylinder is connected to the outer wall of the hopper body, and the upper end of the guide rod is connected to the outer wall of the movable baffle body. The movable baffle body of this hopper safety device with lifting and protective functions consists of a U-shaped structure composed of three steel plates, which can shield the two sides and the back. When the hopper is loading and unloading materials, it can effectively prevent materials from accidentally falling and injuring nearby workers, significantly improving operational safety.
