[0028] During use, through the setting of the first motor 7, so as to drive the belt transmission mechanism 8 to operate;

[0029] At the top of the combustion chassis 1, there is a furnace base 2. At the top of the furnace base 2, there is a hot blast furnace body 3. At the center position of the top of the hot blast furnace body 3, there is an exhaust port 11. On both sides of the surface of the combustion chassis 1, there are cabinet doors 4 installed through hinges. Inside the combustion chassis 1, there is a conveyor rack 17. Inside the conveyor rack 17, there is a chain conveyor belt 18. On the outer wall of one side of the combustion chassis 1, there is a first bearing plate 5. At the top of the first bearing plate 5, there is a screw conveyor body 12 installed through a bracket. One end of the screw conveyor body 12 is connected to the outer wall of the combustion chassis 1. At the other end of the screw conveyor body 12, there is a feed hopper 13.
