Detailed Implementation

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] like Figures 1-6 As shown, a return belt surface cleaning device according to an embodiment of this application includes:

[0030] Cover assembly 1 is located five meters below the head of the conveyor belt. The installation position of cover assembly 1 is described below. Cover assembly 1 covers the outside of the belt body 4. When cleaning the upper part of the belt body 4, the dust generated is blocked by cover assembly 1, preventing dust from flying. Cover assembly 1 has two cooperating upper and lower parts. The two parts facilitate disassembly, maintenance, and operation. An inner cleaning mechanism is arranged inside cover assembly 1 to clean the belt body 4 inside the cover assembly 1. The inner cleaning mechanism is arranged around the belt body 4. An outer cleaning mechanism is located in front of cover assembly 1, also arranged around the belt body 4. The outer cleaning mechanism can clean the upper and lower parts of the belt body 4 in advance, reducing the burden on the inner cleaning mechanism.

[0031] The dust collection component 2 is located on one side of the cover component 1. The top and side walls of the dust collection component 2 are connected to the top and bottom of the cover component 1, respectively. The dust collection component 2 is used to absorb and collect the dust generated during the cleaning of the internal cleaning mechanism inside the cover component 1, thereby reducing the dust from flying around.

[0032] The lifting assembly 3 is located in front of the cover assembly 1. Two sets of lifting assemblies 3 are symmetrically arranged around the belt body 4. A clamping component 17 is fixedly connected to the lifting assembly 3. The clamping component 17 is configured to cooperate with the end of the external cleaning mechanism. The lifting assembly 3 can clamp and lift the external cleaning mechanism, and can make up for daily wear and tear.

[0033] like Figures 2-5 As shown, the cover assembly 1 includes an upper cover 5 and a lower cover 6. The upper cover 5 is located on the upper part of the belt body 4. The top of the upper cover 5 has an upper opening that communicates with the top of the dust collection assembly 2. The lower cover 6 is located at the bottom of the belt body 4. The bottom of the lower cover 6 has a lower opening that communicates with the side wall of the dust collection assembly 2. The structure of the upper cover 5 and the lower cover 6 is described to facilitate subsequent production. The joint of the upper cover 5 and the lower cover 6 has a notch with the same width as the belt body 4 to facilitate the passage of the belt body 4.

[0034] Furthermore, slots 19 are provided at both ends of the upper cover 5, and insert plates 22 are fixedly connected to both ends of the lower cover 6. The insert plates 22 are configured to cooperate with the slots 19. The insert plates 22 are fixedly connected to the slots 19 by fixing screws 21. The insert plates 22 and slots 19 are mated and then fixedly connected by fixing screws 21. The installation relationship between the upper cover 5 and the lower cover 6 is explained.

[0035] Furthermore, the internal cleaning mechanism includes an upper brush sweeper 13, an upper scraper 20, a lower brush sweeper 23, and a lower scraper 24. The upper brush sweeper 13 is rotatably installed inside the upper cover 5, and abuts against the upper part of the belt body 4. The upper scraper 20 is fixedly installed at the bottom of the inner wall of the upper cover 5, and abuts against the upper part of the belt body 4. The lower brush sweeper 23 is rotatably installed inside the lower cover 6, and abuts against the bottom of the belt body 4. The lower scraper 24 is fixedly installed at the top of the inner wall of the lower cover 6, and abuts against the bottom of the belt body 4. The upper scraper 20 is positioned opposite to the lower scraper 23, which can clean the small particles on the upper and lower parts of the belt body 4. The particles then fall into the lower cover 6 and are sucked away by the vacuum assembly 2. The upper scraper 20 and the lower scraper 24 can scrape the upper and lower parts of the belt body 4, making the upper and lower parts of the belt body 4 clean. The cleaned particles will fall into the lower cover 6 and be sucked away by the vacuum assembly 2. The width of the upper scraper 13 and the lower scraper 23 are both greater than the width of the opening, which makes it easier for the particles on the upper part of the belt body 4 to fall into the lower cover 6.

[0036] like Figure 3 and Figure 6 As shown, the external cleaning mechanism includes a cleaning scraper 16. The cleaning scraper 16 is set outside the cover assembly 1 by a clamping member 17. Two cleaning scrapers 16 are symmetrically arranged around the belt body 4. The width of the cleaning scraper 16 is greater than the width of the belt body 4. The cleaning scraper 16 can scrape off larger particles on the upper and lower parts of the belt body 4, reducing the workload of the upper brush cleaner 13 and the lower brush cleaner 23. The cleaning scraper 16 can be made from waste belts, reducing replacement costs and thus reducing the investment in equipment, effectively utilizing waste materials.

[0037] like Figures 1-2 As shown, the vacuuming assembly 2 includes a vacuum cleaner 7, with an upper suction pipe 10 connected to the top of the vacuum cleaner 7 and connected to the upper part of the cover assembly 1. A lower suction pipe 11 is connected to one side of the vacuum cleaner 7 and connected to the bottom of the cover assembly 1. A dust hopper 8 is connected to the bottom of the vacuum cleaner 7, and a dust collection pipe 9 is connected to the bottom of the dust hopper 8.

[0038] Furthermore, both the end of the upper suction pipe 10 and the end of the lower suction pipe 11 are connected to a connecting cover 12, which is connected to the upper part of the cover assembly 1 and the bottom of the cover assembly 1 respectively, to facilitate the adsorption of dust.

[0039] like Figure 3 and Figure 6As shown, the lifting assembly 3 includes a fixed sleeve 14 and a lifting column 15. Two sets of fixed sleeves 14 are arranged opposite each other on the face of the cover assembly 1. Each set of fixed sleeves 14 has two fixed sleeves. The fixed sleeves 14 are fixedly connected to the side wall of the cover assembly 1. A round hole is opened on one side of the fixed sleeve 14. The lifting column 15 is slidably arranged in the fixed sleeve 14. Multiple insertion holes 25 are equally spaced on the lifting column 15. A limit member is provided between the lifting column 15 and the fixed sleeve 14.

[0040] Furthermore, the limiting device includes a socket 25, which is sequentially inserted into the overlapping area of ​​the round hole and the limiting post 18. When the cleaning scraper 16 cleans the belt body 4, the wear will decrease. Through the cooperation of the fixed sleeve 14 and the lifting post 15, the cleaning scraper 16 can continuously clean the belt body 4. The socket 25 can limit the connection position of the fixed sleeve 14 and the lifting post 15.

[0041] like Figure 3 and Figure 6 As shown, the clamping component 17 includes a clamping frame 26 and a clamping plate 27. The top of the clamping frame 26 is fixedly connected to the bottom of the lifting assembly 3, and the top of the clamping plate 27 is rotatably connected to the front end of the clamping frame 26. The clamping frame 26 fixes the external cleaning mechanism to the clamping plate 27 together with the fastening bolts 28. The cooperation between the clamping frame 26 and the clamping plate 27 can fix both ends of the cleaning scraper 16.

[0042] Specifically, the working principle of this return conveyor belt surface material cleaning device is as follows: A cover assembly 1 is installed five meters below the head of the conveyor belt to cover the dust generated during the cleaning of the belt body 4, reducing dust flying. An internal cleaning mechanism is installed inside the cover assembly 1 to clean the fine particles on the upper part of the belt body 4. A connected dust suction assembly 2 is installed on one side of the cover assembly 1 to absorb and centrally process the dust inside the cover assembly 1. An external cleaning mechanism is installed outside the cover assembly 1 to perform preliminary cleaning of the belt body 4. Furthermore, the lifting assembly 3 enables waste recycling, reducing equipment investment costs. It can effectively clean the material accumulated on the surface of the belt body 4, avoiding the risks of manual cleaning and entanglement in the belt body 4. The cleaning time of the combined cleaning scraper 16 can be adjusted at any time according to different working conditions to avoid material accumulation problems.

[0043] The above are merely embodiments of this application and are not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
