DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] A preferred embodiment of a belt conveyor cleaner provided by the utility model is as follows: Figure 1-3The figure shows a cleaner for a belt conveyor, comprising a first-pass polyurethane cleaner 1, a second-pass polyurethane cleaner 2, and a gap cleaner 3. The first-pass polyurethane cleaner 1 comprises a polyurethane scraper 11, a tool holder 12, a hexagonal nut 13, a bolt 15, a spring washer 16, a locking bolt 17, a second bolt 19, a second spring washer 110, a tool holder clamping mechanism 112, and a mechanical swing arm 115.

[0027] The polyurethane scraper 11 is mounted on the tool holder clamping mechanism 112. A hinged support 111 is mounted on one side of the tool holder clamping mechanism 112. The hinged support 111 is mounted with a fixing block 18 via a bolt 19 and a spring washer 110.

[0028] One end of the mechanical swing arm 115 is mounted on the hinged support 111. Both ends of the mechanical swing arm 115 are provided with a spring seat 114 and a hexagonal nut 2 116. A spring 113 is provided between the spring seat 114.

[0029] The tool holder 12 is mounted with a scraper 1 via a bolt 15, a spring washer 16, and a locking bolt 17. A tension rod 14 is mounted on the scraper 1 via a hexagonal nut 13.

[0030] Furthermore, it was found that by providing a first-pass polyurethane cleaner and installing a polyurethane scraper 11 on the blade holder clamping mechanism 112, materials adhering to the surface of the belt conveyor can be effectively removed during the cleaning process, thereby improving cleaning efficiency. Furthermore, the design of scraper 1 allows it to adapt to different belt widths and material thicknesses during the cleaning process, enhancing the adaptability of the cleaner.

[0031] Furthermore, the mechanical swing arm 115, in conjunction with the spring 113, automatically adjusts the scraper pressure during belt conveyor operation, maintaining a stable cleaning effect. Furthermore, the configuration of the second polyurethane cleaner 2 and the empty section cleaner 3 at the head creates a multi-stage cleaning system, effectively reducing maintenance frequency and extending the overall equipment life. The optimized structure of the cleaner components ensures easy operation and maintenance, providing a strong guarantee for the stable operation of the belt conveyor.

[0032] The second polyurethane cleaner 2 on the head includes a polyurethane scraper 21, a blade holder 22, a hexagonal nut 3 23, a hexagonal head bolt 25, a hexagonal nut 4 26, a spring washer 27, a bolt 3 28, and a mechanical swing arm 214;

[0033] The second tool holder 22 is mounted with a second scraper through a fourth hexagonal nut 26, a spring washer 27, and a third bolt 28. A second tensioning rod 24 is provided on the second scraper through a third hexagonal nut 23. One end of the second tool holder 22 is mounted with a fixed angle steel 29 through a hexagonal bolt 25.

[0034] The second mechanical swing arm 214 is mounted on the fixed angle steel 29. A fifth hexagonal nut 210 and a second spring seat 212 are mounted on both ends of the second mechanical swing arm 214. A second spring 211 is mounted between the second spring seats 212. A compensation mechanism 213 is mounted below the second mechanical swing arm 214.

[0035] Furthermore, the polyurethane cleaner, consisting of the polyurethane scraper 21 and the compensation mechanism 213, can self-adjust to the different material properties during operation, effectively avoiding the problem of incomplete cleaning caused by uneven material hardness. The polyurethane scraper has a large contact area with the tape, effectively removing debris from the tape surface. Its excellent wear resistance and compensation capabilities effectively extend the service life of the cleaner.

[0036] Furthermore, the design of compensation mechanism 213 not only adapts to changes in material hardness but also allows real-time adjustments based on the actual operating conditions of the conveyor belt, maintaining a constant contact pressure between the scraper and the belt, thereby further improving cleaning effectiveness. Furthermore, the coordination of hexagonal nut 5 210 and spring seat 212 allows mechanical swing arm 214 to swing flexibly during operation, minimizing damage to the belt and extending the service life of the equipment.

[0037] The air section cleaner 3 includes a fixing plate 31, a bolt 4 32, a hexagonal nut 6 33, a washer 1 34, a washer 2 35, a support rod 36, a bolt 5 311, a hexagonal nut 7 312, a washer 313, and a washer 4 314; the fixing plate 31 is installed on the support rod 36 by means of the bolt 4 32, the hexagonal nut 6 33, the washer 1 34, and the washer 2 35, and the support rod 36 is respectively provided with a hinged rod 1 37 and a hinged rod 2 38, and a polyurethane plate 39 is provided below the hinged rod 1 37 and the hinged rod 2 38 by means of the bolt 5 311, the hexagonal nut 7 312, the washer 313, and the washer 4 314, and a scraper frame 310 is provided at the bottom of the polyurethane plate 39.

[0038] It was further found that by setting up the empty section sweeper 3, the polyurethane plate 39 was installed on the support rod 36 using the hinged rod 1 37 and the hinged rod 2 38 through the bolt 5 311, the hexagonal nut 7 312, the washer 3 313, the washer 4 314 and other structures, the stability and cleaning efficiency of the sweeper during the empty section operation were achieved, the vibration and noise during the cleaning process were reduced, and the flexibility and wear resistance of the polyurethane plate 39 ensured the durability of the cleaning effect.

[0039] When in use, this cleaner should be installed after the conveyor belt in the belt conveyor is installed, and the longitudinal center line of the cleaner should be aligned with the center line of the belt conveyor; during installation, the polyurethane plate 39 must be completely close to the conveyor belt, and then the fixed plate 31 should be connected to the conveyor middle frame; all parts of the cleaner must be cleaned and treated with anti-corrosion before assembly.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
