[0039] Working principle: solid waste fuel is added into the crushing barrel 14, and the first motor 51 drives the rotating shaft 52 to rotate, driving the crushing knife 53 to rotate inside the crushing barrel 14 to crush the solid waste fuel. After the annular frame 41 moves to the lowering of the crushing barrel 14, the second motor 144 is started to drive the closing plate 143 to rotate out of the crushing barrel 14, so that the channel is opened, and the crushed solid waste fuel is filled into the annular frame 41;

The first motor 51 drives the rotating shaft 52 to drive the first reel 61 to rotate in the opposite direction. While the newly added solid waste fuel is pulverized, the cooperation of the driving gear 63 and the driven gear 66 drives the second reel 64 to rotate in the opposite direction, so that the first reel 61 reels the first traction rope 62, and the second reel 64 releases the second traction rope 65, and then the first traction rope 62 pulls the annular frame 4 The solid waste fuel is moved from the pulverizing cylinder 14 to the feed port 13, and is put into the combustion furnace 10 through the mesh plate 12. The solid waste fuel is put onto the step plates 22 of different heights according to the volume of the solid waste fuel, so that the larger the volume of the solid waste fuel is, the higher the height of the step plate 22 is, and the smaller the volume of the solid waste fuel is, the lower the height of the step plate 22 is. The blower blows air into the combustion furnace 10 through the air duct 30, blowing the solid waste fuel to roll down step by step along the step plate 22, and burn while rolling, so that the solid waste fuel burns more fully.
