The mounting block 7 is rotatably connected to the inside of the mounting bracket 6. The electric push rod 8 is fixedly connected to the mounting block 7. In this embodiment, the mounting bracket 6 facilitates the rotation of the mounting block 7, and the electric push rod 8 drives the transmission plate 5 to rotate.

[0038] Reference Figure 4 and Figure 5 A steering device 15 is provided on the outer side of the mounting cylinder 14. The steering device 15 includes a limiting shaft 16. A limiting frame 17 is provided on the outer side of the limiting shaft 16. A slider 18 is provided on the top of the limiting frame 17. A return spring 19 is provided on the bottom of the slider 18. A moving device 20 is provided on the outer side of the slider 18. In this embodiment, the limiting shaft 16 facilitates the angle of the metal brush 1, the limiting frame 17 facilitates the rotation of the limiting shaft 16, and the slider 18 drives the metal brush 1 to move.

[0039] Reference Figure 4 and Figure 5 The limiting shaft 16 is fixedly connected to the mounting cylinder 14, the limiting frame 17 is rotatably connected to the outside of the limiting shaft 16, and the reset spring 19 is fixedly connected to the top of the mounting cylinder 14 away from the slider 18. In this embodiment, the mounting cylinder 14 plays a transmission role, and the reset spring 19 plays a role in facilitating the reset of the metal brush 1.

[0040] Reference Figure 4 and Figure 5 The moving device 20 includes a slide groove 21, a guide rail 22 on the outer side of the slide groove 21, a threaded rod 23 inside the guide rail 22, a threaded cylinder 24 on the outer side of the threaded rod 23, a bidirectional constant speed motor 25 at one end of the threaded rod 23, limit plates 26 at both ends of the guide rail 22, a lifting rod 27 at the bottom of the limit plate 26, and an electromagnet 28 at the bottom of the lifting rod 27. In this embodiment, the slide groove 21 serves as a limit, the guide rail 22 serves as the movement of the slider 18, and the threaded rod 23 serves as a transmission mechanism.

[0041] Reference Figure 4 and Figure 5The slide groove 21 is opened on the outside of the slider 18, the threaded cylinder 24 is set inside the slider 18, the two ends of the threaded rod 23 are rotatably connected to the inside of the guide rail 22, the lifting rod 27 is fixedly connected to the electromagnet 28. In this embodiment, the threaded cylinder 24 plays the role of adapting to the threaded rod 23, the lifting rod 27 plays the role of controlling the height of the metal brush 1, and the electromagnet 28 plays the role of fixing the guide rail 22.

[0042] The implementation principle of this embodiment is as follows:

[0043] When the furnace cover needs to be cleaned, the guide rail 22 is fixed to the outside of the furnace cover using the electromagnet 28, and the height of the metal brush 1 is controlled by the lifting rod 27. Then, the drive motor 13 starts to work and drives the connecting plate 12 and the bottom structure (including the metal brush 1) to rotate to clean the furnace cover. The metal brush 1 can easily remove the residue, and the furnace cover can be cleaned by rinsing with a high-pressure water gun.

[0044] During the cleaning process, the bidirectional constant speed motor 25 drives the threaded rod 23 to rotate. The threaded rod 23 works in conjunction with the threaded cylinder 24 to drive the slider 18 to slide inside the guide rail 22. The slider 18 drives the rotating metal brush 1 to move. Since the surface of the furnace cover is not completely flat, when facing unevenness, the limiting shaft 16 will limit the rotation of the internal part of the limiting frame 17 to tilt the metal brush 1. At the same time, the return spring 19 deforms. After the cleaning of a single area is completed, the electromagnet 28 is turned off and the guide rail 22 is pulled upward. After the metal brush 1 loses connection with the furnace cover, the return spring 19 begins to recover its deformation, driving the metal brush 1 to return to its original position.

[0045] When it is necessary to replace the metal brush 1, the output shaft of the electric actuator 8 begins to extend outward, pushing the transmission plate 5 to rotate outside the mounting shaft 4 (the mounting shaft 4 is located inside the mounting plate 3), and the mounting block 7 rotates inside the mounting bracket 6. When the electric actuator 8 can no longer push the transmission plate 5 to rotate, the metal brush 1 will fall off naturally. Then, a new metal brush 1 is replaced at the bottom of the transmission plate 5. At the same time, the output shaft of the electric actuator 8 begins to retract, pulling the transmission plate 5 to move, and using the slot 10 to engage with the top of the metal brush 1.

[0046] Compared with the prior art, the present invention has the following advantages:

[0047] The drive motor 13, connecting plate 12, and support rod 11 work together to rotate the metal brush 1. The mounting bracket 6, mounting block 7, and electric push rod 8 work together to rotate the transmission plate 5. The addition of mounting shaft 4 facilitates the rotation of the transmission plate 5. The cooperation between the transmission plate 5 and the slot 10 facilitates the replacement of the metal brush 1. Using the above structure, a high-pressure water gun can be used for cleaning, effectively removing residue from the outside of the furnace cover. The cooperation between the limiting shaft 16 and the limiting bracket 17 facilitates the tilting of the metal brush 1. The structure includes a return spring 19 to facilitate the reset of the metal brush 1, a guide rail 22 and a slide groove 21 to facilitate the sliding of the slider 18, a bidirectional constant speed motor 25, a threaded rod 23 and a threaded cylinder 24 to drive the slider 18 to move, a limit plate 26 and a lifting rod 27 to drive the metal brush 1 to rise and fall, and an electromagnet 28 to facilitate the fixing of the guide rail 22. By using the above structure, the metal brush 1 can be moved in a directional manner, which saves physical strength and improves work efficiency.

[0048] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
