[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figures 1 to 3 As shown, this embodiment consists of a flame gun barrel 1, an adjustment and transmission assembly 2, a connecting pipe body 3, a combustion-supporting delivery pipe 4, and a control valve pipeline assembly 5.

[0015] like Figures 1 to 2 As shown, the flame gun tube 1 is the core output component of the combustion operation. One end of it is fixedly connected to one end of the connecting pipe body 3 by bolt fastening. The inside of the flame gun tube 1 is completely connected to the inside of the connecting pipe body 3 to ensure that the fuel gas and combustion-supporting gas can be stably delivered to the flame end of the flame gun tube 1. The upper end of the connecting pipe body 3 is integrally formed with a connecting box 31. The connecting box 31 has a hollow box-shaped structure, which serves as a transition connection component between the connecting pipe body 3 and the combustion-supporting delivery pipe 4, and also provides a supporting foundation for the installation of the adjustment transmission component 2.

[0016] like Figures 1 to 3 As shown, the adjustment transmission assembly 2 is a key structure for adjusting the combustion position and angle. The adjustment transmission assembly 2 includes a first support roller group 21, a second support roller group 22, a connecting bracket 23, a drive motor 24, and an adjustment actuator 25. The connecting bracket 23 has a frame structure, and connecting boxes 26 are fixedly installed at both ends of the connecting bracket 23 by bolts. The lower end of the connecting box 26 is connected to a connecting plate 28 by bolts. The connecting plate 28 is attached to the top of the connecting box 31 and is fastened by a connecting column. Through the cooperation of the connecting box 26 and the connecting plate 28, the adjustment transmission assembly 2 and the connecting box 31 are stably connected, ensuring that the overall structure does not shift during the adjustment process.

[0017] like Figures 1 to 3As shown, the first support roller assembly 21 and the second support roller assembly 22 are rotatably connected to both ends of the connecting box 26 via bearings. The first support roller assembly 21 consists of roller assembly a211 and roller assembly b212, which are connected by roller shaft 213 to enable synchronous rotation and improve the stability of support and movement. A motor mounting plate 27 is installed at the lower end of the connecting box 26. The motor mounting plate 27 is horizontal, and the drive motor 24 is fixedly connected to the motor mounting plate 27 by bolts. A first drive gear 6 is fixed to the motor shaft via a key connection. A second drive gear 7 is connected to the roller assembly a211. A drive chain 8 meshes between the first drive gear 6 and the second drive gear 7. At the same time, a driven gear 9 is connected to the roller assembly b212. A driven chain 10 meshes with the driven gear 9. The drive motor 24 can drive the roller assembly a211 to rotate. Then, the roller assembly b212 is linked through the roller shaft. With the cooperation of the driven gear 9 and the driven chain 10, the burner can move smoothly along a preset trajectory to meet the combustion requirements of different positions.

[0018] like Figures 1 to 2 As shown, one end of the adjusting rod 25 is fixedly connected to the connecting box 26 on one side of the second support roller group 22, and the other end of the adjusting rod 25 is hinged to the end of the connecting box 31. By adjusting the extension or angle of the adjusting rod 25, the connecting box 31 and the flame gun tube 1 and the connecting tube 3 connected thereto can be directly driven to make fine adjustments to the angle, further improving the accuracy of the combustion position and adapting to the heating requirements under complex working conditions.

[0019] To elaborate further, such as Figures 1 to 2 As shown, a combustion-supporting air intake pipe 32 is welded to the side end of the connecting pipe body 3. The interior of the combustion-supporting air intake pipe 32 is completely connected to the interior of the connecting pipe body 3. The combustion-supporting air intake pipe 32 can be connected to an external combustion-supporting gas source, so that the combustion-supporting gas can directly enter the connecting pipe body 3. After being initially mixed with the fuel gas introduced from the connecting box body 31, it is jointly transported to the flame gun tube 1, reducing the gas mixing lag problem and improving combustion efficiency.

[0020] like Figures 1 to 2 As shown, one end of the control valve pipeline assembly 5 is fixedly connected to one end of the combustion supply pipe 4 via a flange and bolts, and the interior of the control valve pipeline assembly 5 is connected to the interior of the combustion supply pipe 4. Several gas supply pipes 51 are uniformly welded to the side end of the control valve pipeline assembly 5. The interior of the gas supply pipes 51 is connected to the interior of the control valve pipeline assembly 5. The gas supply pipes 51 can be connected to different types of fuel gas sources to realize the switching of different gas sources or flow regulation, thereby improving the gas source adaptability and reliability of the burner.
