[0026] Please see Figures 1 to 4The image shows a cleaning device according to the present invention, used for cleaning the mouth of a crucible. The cleaning device includes a collection bucket 10, a support component 20 located at the top port of the collection bucket 10, and an installation component 30 detachably connected to the support component 20. The collection bucket 10 is placed inside the mouth of the crucible. On the one hand, the fitting relationship between the collection bucket 10 and the crucible mouth allows for precise positioning of the entire cleaning device within the crucible mouth; on the other hand, it is used to collect debris generated during the cleaning process of the crucible mouth. In this embodiment, the collection bucket 10 includes a bucket body 11 and a bottom cover 12 detachably connected to the bottom end of the bucket body 11. The edge of the top port of the bucket body 11 is provided with an inclined guide surface 111. The design of the inclined guide surface 111 can guide the debris to fall smoothly into the inside of the bucket body 11 along a specific direction when cleaning the crucible mouth and sweeping the debris off, greatly improving the efficiency of debris collection and reducing the possibility of debris being left outside the bucket body 11. Furthermore, the bottom cover 12 includes a bottom plate portion 121 and a connecting ring portion 122 extending perpendicularly outward from one side of the bottom plate portion 121. The circumferential outer wall of the connecting ring portion 122 is provided with an external thread structure, and the circumferential inner wall of the bottom end of the barrel 11 is provided with an internal thread structure adapted to the external thread structure, so as to realize the threaded connection between the barrel 11 and the bottom cover 12. The threaded connection method facilitates disassembly and installation. When it is necessary to clean the debris in the collection barrel 10, the operator can easily unscrew the bottom cover 12 from the barrel 11, pour out the debris, and then quickly reinstall the bottom cover 12 back into the barrel 11, which greatly improves the maintenance convenience of the cleaning device. In addition, the detachable design of the collection barrel 10 also facilitates the individual replacement or repair of the barrel 11 or the bottom cover 12 when needed, reducing the maintenance cost of the entire cleaning device.

[0027] Furthermore, the support assembly 20 includes a support frame 21 and a support rod 22. The outer circumferential edge of the support frame 21 is fixedly connected to the inner circumferential wall of the top end of the collection bucket 10. As a specific example, in this embodiment, the support frame 21 is a cross structure, and the ends of the four arms of the cross structure are respectively fixedly connected to the inner circumferential wall of the top end of the collection bucket 10. The support rod 22 is fixedly mounted on the side of the support frame 21 away from the bottom end of the collection bucket 10. The end of the support rod 22 away from the support frame 21 is provided with an external thread structure. The support rod 22 is provided with at least two sliding grooves 201, which are arranged along the axial direction of the support rod 22. As a specific example, in this embodiment, the support rod 22 is provided with two opposing sliding grooves 201.

[0028] Furthermore, the mounting assembly 30 includes a lifting sleeve 31 and a connector 34 rotatably connected to the lifting sleeve 31. The lifting sleeve 31 is threadedly connected to the support rod 22 in the support assembly 20 to realize the vertical movement of the lifting sleeve 31 along the axial direction of the support rod 22. In this embodiment, the lifting sleeve 31 includes a first sleeve section 311 and a second sleeve section 312. The circumferential inner wall of the first sleeve section 311 is provided with an internal thread structure adapted to the external thread structure. The second sleeve section 312 is rotatably connected to the bottom end of the first sleeve section 311. The circumferential inner wall of the second sleeve section 312 is provided with at least two sliders 32 adapted to the slide groove 201. When the first sleeve section 311 moves axially along the support rod 22 due to rotation, the sliders 32 of the second sleeve section 312 will slide smoothly in the slide groove 201, thereby driving the second sleeve section 312 to move vertically along the axial direction of the support rod 22 synchronously. It should be understood that the cooperative design of the slider 32 and the groove 201 restricts the second sleeve section 312 to move only vertically up and down, so that the second sleeve section 312 maintains a stable linear motion state during the movement, ensuring that the grinder 40 can always maintain a precise position and angle during operation, effectively avoiding adverse effects on the grinder 40 installed at its end due to shaking, and greatly improving the quality and efficiency of cleaning work.

[0029] Furthermore, the circumferential outer wall of the first sleeve section 311 is provided with an anti-slip structure. In this embodiment, the anti-slip structure consists of multiple rectangular protrusions 33, which are spaced apart circumferentially along the first sleeve section 311. The design of the anti-slip structure can provide greater friction when the operator rotates the first sleeve section 311, thereby improving the convenience and stability of the operator in rotating the first sleeve section 311.

[0030] Furthermore, a grinder 40 is fixedly connected to the end of the connector 34 away from the lifting sleeve 31 via a mounting sleeve 35. The grinding head of the grinder 40 is positioned towards the collection bucket 10. The grinder 40 in this embodiment is prior art and can operate simply by connecting to a power source, and will not be described in detail in this application. In this embodiment, the connector 34 includes a rotating ring 341, a connecting arm 342 connected to one radial side of the rotating ring 341, and a fixing ring 343 connected to the end of the connecting arm 342 away from the rotating ring 341. The connector 34 is arranged radially along the support rod 22. The rotating ring 341 is rotatably sleeved on the circumferential outer wall of the second sleeve section 312. The grinder 40 is press-fitted with the circumferential inner wall of the fixing ring 343 via the mounting sleeve 35. It should be noted that in this embodiment, the connector 34 is arranged radially along the support rod 22.

[0031] Furthermore, the mounting sleeve 35 includes a clamping part 351 and a blocking part 352. The clamping part 351 has a cylindrical structure and is sleeved on the circumferential outer wall of the grinder 40. As a specific example, in this embodiment, the clamping part 351 is made of rubber. With the good elasticity and friction of rubber, the grinder 40 forms an interference fit with the circumferential inner wall of the fixing ring 343 through the clamping part 351, so as to achieve a stable fixation of the grinder 40 on the fixing ring 343. This fixing method is not only convenient to install, but also can effectively buffer the vibration generated when the grinder 40 is working, and extend the service life of the grinder 40 and the entire cleaning device. Furthermore, the blocking part 352 has a truncated conical structure. The small-diameter end of the blocking part 352 is connected to the end of the clamping part 351 facing the collection bucket 10, and the large-diameter end of the blocking part 352 extends towards the collection bucket 10 to form a gradually expanding blocking surface. The blocking part 352 can effectively prevent the material from splashing around during the cleaning process of the grinding machine 40 cleaning the crucible mouth. As a specific example, in this embodiment, the blocking part 352 is made of transparent material, such as transparent acrylic material, so that the operator can observe the cleaning situation during the grinding and cleaning process and adjust the position and angle of the grinding machine 40 in time, further improving the practicality and ease of operation of the cleaning device.

[0032] In practical use, the working principle of the cleaning device of this utility model is as follows: When cleaning is required, the collection bucket 10 can be placed inside the crucible opening first. Then, the first sleeve section 311 of the rotating lifting sleeve 31 drives the second sleeve section 312 to move up and down along the axis of the support rod 22. Since the grinder 40 is connected to the second sleeve section 312 through the connecting piece 34, the grinder 40 will also move up and down synchronously. When the grinding head of the grinder 40 contacts the inner wall of the crucible opening, the first sleeve section 311 is stopped to fix the height position of the grinder 40. Then, the grinder 40 is started to start the grinding operation. During grinding, since the rotating ring 341 in the connecting piece 34 is rotatably sleeved on the second sleeve section 312, the grinder 40 can be driven to rotate around the central axis of the support rod 22 by moving the fixing ring 343, so that the grinder 40 can flexibly surround the crucible opening to carry out all-round grinding operations, ensuring that there are no dead corners in the cleaning. During the grinding process, the splashed material is blocked by the blocking part 352 in the mounting sleeve 35 and falls downward into the collection bucket 10 under the action of gravity, achieving efficient collection of material debris. After the grinding operation is completed, the entire cleaning device can be removed from the inside of the crucible opening, and the bottom cover 12 at the bottom of the collection bucket 10 can be rotated to disassemble the bucket body 11 and the bottom cover 12, so that the bottom cover 12 and the inside of the bucket body 11 can be cleaned.

[0033] In summary, the beneficial effects of the cleaning device of this utility model are as follows: by setting up a collection bucket, a support component, and an installation component, the grinding machine can efficiently clean the crucible opening. The operation is convenient and the cleaning efficiency is greatly improved. Specifically, the collection bucket is used to position the entire cleaning device inside the crucible opening and can be used to collect material debris generated during the cleaning process, which greatly improves the efficiency of debris collection. The installation component includes a lifting sleeve and a connecting piece. The end of the connecting piece away from the lifting sleeve is fixedly connected to the grinding machine through the installation sleeve. The lifting sleeve is threadedly connected to the support component. The precise adjustment of the cleaning height of the grinding machine can be achieved by moving the lifting sleeve axially in the support component. Moreover, the rotational connection between the connecting piece and the lifting sleeve allows the grinding machine to flexibly surround the crucible opening for all-round grinding operations, ensuring that there are no dead corners in the cleaning and effectively improving the cleaning quality.
