[0032] In order to help those skilled in the art better understand the present invention, 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 should fall within the scope of protection of the present invention.

[0033] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0034] The following is combined with Figure 1-8 This application is described in further detail.

[0035] refer to Figure 1-3 The conveyor belt head cleaning device shown in the figure includes: a frame, on which a head roller 1, a high-pressure flushing pipe 2, a sweeper mechanism 3, an air knife mechanism 4 and a water collecting tray 5 are arranged. The water collecting tray 5 is arranged below the head roller 1, the high-pressure flushing pipe 2, the sweeper mechanism 3 and the air knife mechanism 4. One end of the conveyor belt is wound around the head roller 1, and the high-pressure flushing pipe 2, the sweeper mechanism 3 and the air knife mechanism 4 are sequentially arranged below the conveyor belt from one end of the head roller 1. In this way, when in use, the conveyor belt is wound around the head roller 1, and the return conveyor belt is flushed by the high-pressure flushing pipe 2, and then the water stains remaining on the return surface of the conveyor belt are cleaned by the sweeper mechanism 3, and finally removed by the air knife mechanism 4 The moisture on the surface of the conveyor belt is removed, thereby ensuring that the surface of the conveyor belt is dry after cleaning, which will not affect the subsequent material transportation. In order to avoid splashing of flushing water during high-pressure flushing, a protective cover can be set on the frame to wrap the cleaning end of the conveyor belt, and a water collecting tray 5 is set at the bottom to collect the flushing water. The sewage is then discharged into the sewage collection pool through the pipeline. Since the return working surface of the conveyor belt is first flushed by the high-pressure flushing pipe 2, the powdery attachments and high-viscosity materials attached to the return working surface of the conveyor belt are washed away, and then cleaned by the sweeper mechanism 3 to scrape off the remaining materials. Finally, the wind knife mechanism 4 is used to spray to blow away the remaining moisture, ensuring that the return working surface of the conveyor belt is dry and tidy.

[0036] refer to Figure 1-3 As shown, in order to avoid splashing of high-pressure water when flushing the conveyor belt, an isolation cover 6 is provided at one end of the head roller 1 of the frame, and the high-pressure flushing pipe 2 is arranged in the isolation cover 6. The bottom of the isolation cover 6 is connected to the water collecting tray 5, so that the splashing high-pressure water is blocked and collected at the bottom of the isolation cover 6, and the sewage collected by the water collecting tray 5 will also be collected at the bottom of the isolation cover 6, and finally transported to the sewage pool through the pipeline.

[0037] refer to Figure 4As shown, in order to ensure the flushing effect of the conveyor belt, the extension direction of the high-pressure flushing pipe 2 is consistent with the axial direction of the head roller 1. A plurality of nozzles are provided on the high-pressure flushing pipe 2. The high-pressure water sprayed from the plurality of nozzles forms a water jet, covering the return working surface of the conveyor belt, thereby ensuring the flushing effect.

[0038] Further optimization is that, in order to improve the cleaning effect, multiple high-pressure flushing pipes 2 and sweeper mechanisms 3 can be set, for example, two water jets (high-pressure flushing pipes 2) and three sweeper mechanisms 3 and an air knife mechanism 4 are set. The return belt containing sticky material is first flushed by the first water jet. The water jet disperses and floats the sticky material and then passes through the first sweeper mechanism 3 to directly remove 90% of the sticky material on the return conveyor belt. This is followed by the second water jet to completely flush away the trace amount of sticky material. There are a large number of flushing water droplets on the surface of the conveyor belt, which are removed by the second sweeper mechanism 3, and then the third sweeper removes water vapor again. At this time, there is no obvious water on the surface, and only a certain amount of moisture remains on the surface of the conveyor belt. Finally, there is an air knife mechanism 4 to remove moisture from the surface of the conveyor belt.

[0039] refer to Figure 5 As shown, the sweeper mechanism 3 includes a cross bar 31 and a plurality of scraper assemblies. The cross bar 31 is horizontally arranged above the water collection tray 5; the plurality of scraper assemblies are arranged on the cross bar 31 in sequence along the axial direction of the cross bar 31, and the scraper assembly includes a scraper 32 with the blade facing the conveyor belt. The scrapers 32 of the plurality of scraper assemblies are arranged in sequence below the return working surface of the conveyor belt to scrape off moisture and residue from the return working surface of the conveyor belt, and each scraper 32 is installed independently for easy replacement and maintenance.

[0040] refer to Figure 5-Figure 8As shown, due to the long-term extrusion and friction of the scraper 32 and the material on the outer contact surface of the conveyor belt, the conveyor belt surface will be hardened and slipped during transportation, which accelerates the aging of the conveyor belt carrying surface. In order to reduce the damage of the scraper 32 to the conveyor belt, the scraper assembly also includes a mounting seat 33, a screw 34, a nut 35, a mounting shaft 36 and a knife seat 37. The mounting seat 33 is arranged on the cross bar 31, and a mounting plate 331 is arranged in the mounting seat 33. The mounting seat 33 is provided with a straight groove 332 on both sides of the mounting plate 331. The two ends of the mounting shaft 36 are respectively slidably arranged in the straight groove 332. One end of the screw 34 is threadedly connected to the mounting plate 331, and the other end passes through the mounting plate 331. The shaft 36 and the nut 35 are sleeved on the screw rod 34. The nut 35 is set on the side of the mounting shaft 36 away from the mounting plate 331. The length direction of the I-shaped groove 332 is consistent with the axial direction of the screw rod 34; the knife seat 37 is set on the mounting shaft 36, and the scraper 32 is set on the knife seat 37. In this way, when in use, multiple scraper assemblies are strung on the cross bar 31 through the limiting holes on the mounting seat 33, and the limiting ribs on the cross bar 31 ensure that the directions of multiple scrapers 32 are consistent. By passing the mounting shaft 36 on the screw rod 34 (the axial direction of the mounting shaft 36 is perpendicular to the axial direction of the screw rod 34), the mounting shaft 36 can be rotated to move between the two I-shaped grooves 33 2, adjust the height of the knife seat 37 to achieve the purpose of adjusting the height of the scraper 32 to adapt to the cleaning work of the return working surface of the conveyor belt at different heights, that is, the scraper 32 can be lifted and lowered, and a torsion spring 361 is provided on the mounting shaft 36, both ends of the torsion spring 361 are in contact with the inner side of the knife seat 37, and the side of the knife seat 37 away from the torsion spring 361 is against the mounting seat 33. When installing, it is preferred to face the mounting side of the torsion spring 361 towards the side of the return movement direction of the conveyor belt. When the conveyor belt moves, the material residue on the surface of the conveyor belt is scraped off by the scraper 32. Since the knife seat 37 is rotatably arranged on the mounting seat 33, when the return working surface of the conveyor belt is not When leveling, if the horizontal height of the return working surface of the conveyor belt becomes lower or encounters a firmly adhered material, the scraper 32 is subjected to greater resistance, causing the scraper 32 to rotate toward the side where the return working surface of the conveyor belt moves (compressing the torsion spring 361), thereby achieving adaptive adjustment or avoidance. If the horizontal height of the return working surface of the conveyor belt becomes higher, the resistance encountered by the scraper 3 becomes smaller, and the elastic force of the torsion spring causes the scraper 32 to rotate toward the side away from the return working surface of the conveyor belt, thereby achieving compensation and ensuring the effect of cleaning the conveyor belt. In this way, the scraper 32 has the function of adapting itself according to the situation of the return working surface of the conveyor belt, causing less damage to the surface of the conveyor belt and extending the service life of the conveyor belt.

[0041] refer to Figure 5 and Figure 8As shown, in order to facilitate the installation of the scraper assembly, the scraper assembly also includes two connecting seats 38 and two pull rods 39. Both ends of the cross bar 31 are provided with slides 311. The two connecting seats 38 are provided with slide rails extending in the vertical direction. The two slides 311 are respectively slidably set on the slide rails of the two connecting seats 38. The two pull rods 39 are slidably set on the connecting seats 38. The bottom end of the pull rod 39 is connected to the end of the cross bar 31. The axial direction of the pull rod 39 is consistent with the extension direction of the slide rail. A spring 391 is sleeved on the pull rod 39. The spring 391 Provide upward thrust for the pull rod 39, so that the scraper assembly as a whole has adaptive force. The slides 311 at both ends of the cross bar 31 can move up and down on the two connecting seats 38. Combined with the elastic force of the spring 391, when the height of the return working surface of the conveyor belt changes, the height of the blades of multiple scrapers 32 can be raised and lowered synchronously (when the return working surface of the conveyor belt becomes higher, the height of the blade of the scraper 32 increases, and when the return working surface of the conveyor belt becomes lower, the height of the blade of the scraper 32 decreases), further reducing damage to the conveyor belt.

[0042] refer to Figure 5 and Figure 8 As shown, in order to limit the return of the conveyor belt and ensure the cleaning effect, a supporting roller 7 is further provided on the frame. The supporting roller 7 is arranged between the head roller 1 and the sweeper mechanism 3. The return working surface of the conveyor belt passes over the supporting roller 7 to support the return surface of the conveyor belt. In addition, in order to limit the return surface of the conveyor belt from being too high, a pressure roller 8 is further provided on the frame. The pressure roller 8 is arranged above the sweeper mechanism 3. The return working surface of the conveyor belt passes under the pressure roller 8 to maintain an appropriate distance between the return working surface of the conveyor belt and the scraper 32 and will not separate from the blade of the scraper 32.

[0043] In summary, when in use, the conveyor belt is wound around the head roller 1, and the return conveyor belt is flushed by the high-pressure flushing pipe 2, and then the water stains remaining on the return surface of the conveyor belt are cleaned by the sweeper mechanism 3, and finally the moisture on the surface of the conveyor belt is removed by the wind knife mechanism 4, thereby ensuring that the surface of the conveyor belt is dry after cleaning, and will not affect the subsequent material transportation. In order to avoid splashing of flushing water during high-pressure flushing, a protective cover can be set on the frame to wrap the cleaning end of the conveyor belt, and a water collection tray 5 is set at the bottom to collect flushing water, and then the sewage is discharged into the sewage collection pool through the pipeline. Since the return working surface of the conveyor belt is first flushed by the high-pressure flushing pipe 2, the powdery attachments and high-viscosity materials attached to the return working surface of the conveyor belt are washed away, and then it is cleaned by the sweeper mechanism 3 to scrape off the remaining materials, and finally the wind knife mechanism 4 is used to blow away the remaining moisture, ensuring that the return working surface of the conveyor belt is dry and tidy.

[0044] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations directly derived or imagined by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the scope of protection of the present invention.
