Protective device for iron and steel smelting ore feeding equipment

The invention relates to the technical field of iron and steel smelting and discloses a protective device for iron and steel smelting ore feeding equipment. The protective device comprises a supporting frame, wherein a first solenoid is fixedly mounted on a supporting plate, a first spring is arranged on the right side of the first solenoid, a power box is arranged on the supporting plate, a rotating wheel is arranged on the front side of the supporting plate, a moving plate is arranged below the rotating wheel, a connecting rod is fixedly connected with the lower part of the moving plate, anda second spring is arranged on the right side of the connecting rod. When feeding is ended, a second motor stops rotating, a power supply of the first solenoid is disconnected, the first solenoid hasno attractive force on first iron, a motor base moves upwards under the elasticity of the first spring, a pouring hopper moves to the original position under the pulling force of the second spring and is away from a smelting
