Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0017] Reference Figures 1-4 This embodiment of the present invention provides an adjustable nozzle for a boiler burner, comprising: The support mechanism 100 includes a furnace wall 110, an output pipe 120 that is installed on the furnace wall 110 and connected to the output end of the burner, a connecting pipe 130 disposed at the end of the output pipe 120, and nozzles 140 of different types fixed to the end of the connecting pipe 130. The switching mechanism 200 includes a switching component 210 for switching different types of nozzles 140, and a locking component 220 for positioning the nozzles 140 after switching.

[0018] The cooperation between the switching component 210 and the locking component 220 breaks the traditional fixed mode of "one nozzle for one use" and provides basic structural support for the subsequent realization of multi-fuel adaptation or multi-condition combustion requirements. It greatly improves the overall adaptability and practicality of the nozzle and facilitates later maintenance and component replacement.

[0019] Specifically, the switching component 210 includes a mounting bracket 211 for fixing the connecting pipe 130, a plurality of fixing teeth 212 fixed to the bottom of the mounting bracket 211, protective parts 213 provided on both sides of the fixing teeth 212 for protection, a motor 214 fixed to the outer wall of the furnace wall 110, a drive wheel 215 fixed to the output end of the motor 214, a rotating rod 216 rotatably mounted on the furnace wall 110, a drive gear 217 fixed to the end of the rotating rod 216 and meshing with the fixing teeth 212, and a driven wheel 218 fixed to the other end of the rotating rod 216.

[0020] The motor 214 drives the drive wheel 215, which transmits power to the drive gear 217 via the rotating rod 216. The drive gear 217 and the fixed tooth 212 at the bottom of the mounting bracket 211 mesh with each other, which realizes the mechanized switching of the connecting pipe 130 and the connected nozzle 140. This replaces the traditional method of manually disassembling and replacing the nozzle, reducing the intensity of operation and the switching time. At the same time, the protective parts 213 on both sides of the fixed tooth 212 can effectively protect the meshing transmission structure and prevent the motor 214 from excessively driving the mounting bracket 211 to move, which would cause misalignment.

[0021] Furthermore, a synchronous belt 219 is fitted onto the surfaces of the driving wheel 215 and the driven wheel 218, and the synchronous belt 219 is used for the transmission of the driving wheel 215 and the rotating rod 216.

[0022] Preferably, the protective component 213 includes a buffer tooth 2131 slidably mounted on the bottom of the mounting bracket 211, a limiting groove 2132 formed on the bottom of the mounting bracket 211, a limiting slider 2133 slidably mounted inside the limiting groove 2132, and a buffer spring 2134 fixed inside the limiting groove 2132 and fixed to the limiting slider 2133.

[0023] When the fixed protrusion 212 meshes with the drive gear 217, if there is a momentary meshing deviation or external force interference, the buffer spring 2134 can apply a buffering force to the buffer protrusion 2131 through its own elastic deformation, so as to prevent the fixed protrusion 212 from directly bearing the impact and play an overload protection role; at the same time, the cooperation between the limiting slide groove 2132 and the limiting slider 2133 can limit the movement direction of the buffer protrusion 2131, ensuring effective switching of the nozzle 140.

[0024] Furthermore, the locking component 220 includes a fixing protrusion 221 fixed to the top of the surface of the output tube 120, a connecting rod 222 laterally inserted into the fixing protrusion 221, a conical locking block 223 fixed to one end of the connecting rod 222, a compression spring 224 connected between the fixing protrusion 221 and the conical locking block 223, and a conical slot 225 formed on the surface of the mounting bracket 211 and used in conjunction with the conical locking block 223 to limit the nozzle 140.

[0025] The conical locking block 223 is engaged inside the conical locking groove 225.

[0026] Under the elastic action of the compression spring 224, the conical locking block 223 can be tightly locked into the conical locking groove 225 on the surface of the mounting bracket 211; the conical structure can quickly achieve mechanical locking after the nozzle 140 is switched to the position, and can be quickly released and unlocked, which not only prevents the nozzle 140 from shifting position due to the vibration of the boiler during operation, but also ensures smooth switching of the nozzle 140.

[0027] Furthermore, a positioning rod 226 is fixedly installed on the surface of the conical block 223, and a positioning hole for use with the positioning rod 226 is opened on the surface of the fixing convex plate 221, through which the positioning rod 226 passes.

[0028] The positioning rod 226 slides through the positioning hole, creating a precise guiding structure. This restricts the movement trajectory of the conical block 223, preventing it from radially shifting under the action of the compression spring 224, and ensuring that the conical block 223 is accurately aligned with the conical slot 225.

[0029] When it is necessary to replace the nozzle 140 during use, start the motor 214. The motor 214 drives the drive wheel 215 to rotate, which drives the driven wheel 218 and the rotating rod 216 to rotate synchronously through the synchronous belt 219. The drive gear 217 at the end of the rotating rod 216 meshes with the fixed tooth 212 at the bottom of the mounting bracket 211, which drives the mounting bracket 211, the connecting pipe 130 and the nozzle 140 to move until the target nozzle 140 moves to the working position where it is connected to the output pipe 120.

[0030] When the nozzle 140 is switched into position, the compression spring 224 in the locking component 220 releases its elastic force, pushing the conical block 223 to move along the guide direction of the positioning rod 226, so that the conical block 223 is accurately engaged in the conical groove 225 on the surface of the mounting bracket 211, thus completing the locking and fixing of the nozzle 140.

[0031] In summary, the cooperation between the switching component 210 and the locking component 220 breaks the traditional fixed mode of "one nozzle for one use" and provides basic structural support for the subsequent realization of multi-fuel adaptation or multi-condition combustion requirements. It greatly improves the overall adaptability and practicality of the nozzle and facilitates later maintenance and component replacement.
