Self-help fuel filling combustion furnace

The utility model discloses a self-help fuel filling combustion furnace. The self-help fuel filling combustion furnace comprises a furnace body; a chimney nipple is arranged at a smoke outlet on the upper part of the back of the furnace body; the side face of the furnace body is provided with an air inlet; the upper surface of the furnace body is provided with a fire hole and a fuel inlet; a movable ash bucket is arranged in a lower inner cavity of the furnace body; a separating plate and a backflow plate are arranged in the furnace body; the separating plate is arranged in the inner cavity of the furnace body at the fuel inlet, and the upper edge of the separating plate is perpendicularly fixedly connected with the upper wall of the furnace body; the backflow plate is obliquely arranged in the inner cavity of the furnace body, the middle of the backflow plate is fixedly connected with the side wall of the furnace body, and the lower edge of the backflow plate is fixedly connected with the lower wall of the furnace body; the backflow plate is uniformly provided with backflow holes; the side wall, corresponding to the backflow plate, of the furnace body is provided with the smoke outlet. The inner cavity of the furnace body is separated into a plurality of cavities by the separating plate, excessive fuel is prevented from directly filling the inner cavity of the furnace body to avoid fuel accumulation, problems of high fuel consumption, low fuel combustion rate and the like caused by the fuel accumulation are eliminated, the fuel combustion rate is improved, soot generated by insufficient combustion in the furnace body can be subjected to secondary combustion, pollution is reduced, and the labor intensity is reduced.
