After the smoke and exhaust gas inside the furnace body 1 is treated, the clutch 21 can be started to connect the rotating rod 15 and the connecting rod 1 20. At this time, with the rotation of the rotating rod 15, the connecting rod 1 20 can be driven to rotate synchronously, thereby driving the pulley 1 22 to rotate. Driven by the rotation of the pulley 1 22, the belt 28 runs, and then drives the pulley 24 to rotate, thereby driving the reciprocating screw 23 to rotate. The circular brush 25 rotates, and driven by the rotation of the reciprocating screw rod 23, the circular brush 25 moves back and forth on the inner wall of the furnace body 1, thereby driving the connecting rod 26 to move synchronously. Driven by the movement of the connecting rod 26, the closed door 27 moves synchronously, and then the circular brush 25 cleans the inner wall of the furnace body 1. When the circular brush 25 moves toward the closed door 27, the objects baked inside the furnace body 1 can be pushed out, thereby achieving the purpose of automatic unloading, and ensuring the cleanliness of the inner wall of the furnace body 1 after unloading, which will not affect the next raw material baking.
