Since the air outlet of the blower 27 is arranged in a part of the space inside the housing 1, the gas will not escape, and the air can be supplied to the equipment more stably to prevent the flame from becoming smaller and causing incomplete combustion, thereby affecting normal operation. The transmission end of the first servo motor 5 is fixedly installed with a spiral knife group 7, and the interior of the feed pipeline 3 is connected with the spiral knife group 7. When the fuel enters the feed pipeline 3, it will be immediately transported away by the spiral knife group 7 under the action of the first servo motor 5, avoiding blockage, and allowing the equipment to supply fuel normally to avoid untimely fuel output. A second servo motor 8 is fixedly installed on one side of the baffle 6, and the transmission end of the second servo motor 8 is fixedly installed with a spiral knife group 7. A transmission shaft 9 is fixedly installed at one end of the transmission shaft 9, and a first gear 10 is fixedly installed at one end of the transmission shaft 9. The teeth of the first gear 10 are meshed with a roller 11. When the fuel enters the inside of the roller 11, the second servo motor 8 will drive the first gear 10 to rotate through the transmission shaft 9, so that the meshed roller 11 rotates, and the fuel is tumbled to avoid the fuel piling up and not being able to fully burn, better prevent fuel waste, and improve utilization. The surface of the roller 11 is provided with an air supply hole 12, and the air blown by the blower 27 will come out of the air supply hole 12 to achieve full combustion of the fuel and avoid the problem of extinguishing due to insufficient air supply. An outer protective shell 13 is welded on one side of the shell 1, and the inner part of the outer protective shell 13 is clamped to the roller 11 to prevent external The environment interferes with the combustion of fuel inside the drum 11, and can protect the staff and reduce safety hazards. The surface of the outer protective shell 13 is welded with an air pipe 14, and the surface of the outer protective shell 13 is provided with four elliptical long holes, and the elliptical long holes are welded to the air pipe 14 to avoid air dispersion affecting the size of the flame. One end of the air pipe 14 is fixedly connected with an adjusting member 15, and half of the adjusting member 15 is provided with a square hole. The gas blown out by the blower 27 can only reach the drum 11 from the adjusting member 15. One end of the adjusting member 15 is movably sleeved with a sleeve pipe 16, and the sleeve pipe 16 can control the size of the square hole on the surface of the adjusting member 15, thereby adjusting the amount of air entering, and then controlling the size of the flame. The bottom of the shell 1 is fixedly installed with a load-bearing plate 25.A limiting groove 26 is provided on the top of the load-bearing plate 25, and the interior of the limiting groove 26 is slidably connected to the sleeve tube 16. A fixing component 17 is fixedly installed on one end of the sleeve tube 16, and a sliding plate 18 is fixedly connected to one end of the fixing component 17. A closing plate 19 is fixedly installed on one side of the sliding plate 18. A sleeve box 20 is fixedly installed on the inside of the shell 1, and the interior of the sleeve box 20 is slidably connected to the sliding plate 18. The sleeve box 20 provides support for the sliding plate 18 to prevent the device from being stuck due to skewness, which affects the discharge of materials. A control component 21 is slidably connected to one side of the sliding plate 18, and a clearance hole is provided on one side of the control component 21. The top of the clearance hole is fixedly connected to the feeding hopper 2, and the bottom of the clearance hole is fixedly connected to the conveying pipeline 3. The closing plate 1 9 is located inside the control component 21, and the size of the closing plate 19 is the same as the clearance hole and the connection port 4. When the sliding plate 18 is slid, the size of the connection port 4 can be controlled, that is, the amount of fuel entering can be controlled so that the fuel can be quickly replenished or excessive delivery can be avoided to cause unstable flames. A second gear 22 is meshed on one side of the sliding plate 18, and a support shaft 23 is fixedly installed at the bottom of the second gear 22. A rotating handle 24 is fixedly installed on the top of the second gear 22, that is, rotating the rotating handle 24 can control the sliding plate 18 and further control the fuel supply. An extension plate 28 is fixedly installed inside the housing 1, and an ignition component 29 is fixedly installed on one side of the extension plate 28. The ignition component 29 can ignite the fuel transmitted into the drum 11 to achieve combustion. ,

[0027] The working principle and use process of the utility model are as follows: first, the fuel is transported into the feed hopper 2, and the first servo motor 5 is started at this time, so that the spiral cutter group 7 rotates to transport the fuel to the drum 11, and the ignition component 29 is controlled to ignite the fuel inside the drum 11. Since the feed pipe 3 is connected to one end of the drum 11, the second servo motor 8 is started at this time, so that the second servo motor 8 drives the first gear 10 to rotate through the transmission shaft 9. At this time, the drum 11 meshed with the first gear 10 rotates, and the fuel inside the drum 11 is continuously rolled. In the same process, the blower 27 is started to blow out a large amount of air. When it is necessary to adjust the flame to make it larger, the rotating handle 24 is rotated. At this time, the rotating handle 24 will drive the second gear 22 to rotate, so that the meshing The sliding plate 18 slides, and the closing plate 19 fixedly installed on one side of the sliding plate 18 slides toward the side of the control component 21, so that the area of ​​the connecting port 4 is expanded. At this time, a large amount of fuel falls through the connecting port 4, and is sent into the drum 11 under the action of the spiral knife group 7 for combustion. The sliding plate 18 is driven to slide by the rotating second gear 22, and the fixed components 17 fixedly installed on both sides of the sliding plate 18 push the sleeve tube 16 to slide synchronously. At this time, the adjusting member 15 sleeved inside the sleeve tube 16 will extend out, and the size of the square hole opened on the surface of the adjusting member 15 will be expanded, so that a large amount of air blown out by the blower 27 flows through the adjusting member 15 and reaches the outer protective shell 13 from the air supply pipe 14. At this time, the air will blow to the fuel through the air supply hole 12 to make it fully burned.
