Novel sealing device of sintering machine

The novel sealing device for the sintering machine comprises a sealing plate which is in contact with the bottom of a trolley, the supporting plate is arranged below the sealing plate; the upper part of the rotating shaft seat is provided with an opening, the rotating shaft seat is a hollow pipe with an arc-shaped vertical section, the supporting plate is rotatably arranged in the rotating shaft seat, and the upper part of the supporting plate extends out of the opening of the rotating shaft seat and is connected with the sealing plate; and before the trolley is not in contact with the sealing plate, the front end of the sealing plate is lower than the rear end of the sealing plate. According to the sealing device, the supporting plate is connected with the sealing plate, the supporting plate is rotatably arranged in the rotating shaft seat, the contact area of the supporting plate and the inner wall of the rotating shaft seat is smaller, the friction force is small, the supporting plate can be driven to rota
