Both ends of the scraper assembly 59 are fixedly connected to sliders 510, and the outer side of the slider 510 is slidably connected to the inner side of the slide groove 57; the scraper assembly 59 includes a scraper bracket 591, one of the scraper brackets 591 is slidably connected to a guide block 592 at the upper end, and a scraper 593 is fixedly connected to the upper end of the guide block 592, and the other scraper bracket 591 is slidably connected to the upper end of the guide column 594, and a brush 595 is fixedly connected to the upper end of the guide column 594.

[0028] As a further implementation scheme of the above technical solution: a plurality of guide posts 594 and brushes 595 are provided, wherein the guide posts 594 are cylindrical in shape, and one end of the brush 595 is arc-shaped. The guide posts 594 and the brushes 595 are evenly and equidistantly distributed on the upper end of another scraper bracket 591. The bottom of the guide posts 594 is in contact with the hydraulic oil. The arc-shaped setting enables it to better fit the various shapes of the surface of the conveyor head, especially the corners and arc-shaped transition areas, effectively sweeping away the fine sticky materials remaining after the scraper 593 is scraped, thereby ensuring smooth material transmission;

[0029] As a further implementation scheme of the above technical solution: two chute grooves 57 and two sliders 510 are provided, and the chute grooves 57 and the sliders 510 are symmetrically arranged with the midline of the upper end of the cleaning plate 56 as the axis. There is a one-to-one correspondence between the chute grooves 57 and the sliders 510. The chute grooves 57 and the sliders 510 are slidably connected to provide a sliding track for the slider 510 of the scraper assembly 59, so that the scraper assembly 59 can be stably adjusted in the vertical direction to prevent it from being excessively deflected or separated from the cleaning plate 56 during operation;

[0030] As a further implementation of the above technical solution: two scraper brackets 591 are provided, and the scraper brackets 591 are symmetrically arranged with the midline of the upper end of the cleaning plate 56 as the axis. The scraper brackets 591 are slidably connected to the inner side of the slide 57. The upper end of the scraper bracket 591 is provided with a beveled edge. The interior of the scraper bracket 591 is filled with hydraulic oil. The beveled edge of the upper end of the scraper bracket 591 can facilitate the falling of dust after cleaning and prevent dust from accumulating on the upper end of the scraper bracket 591.

[0031] As a further implementation scheme of the above technical solution: a plurality of springs 58 are provided, and the springs 58 are provided between the bottom of the scraper assembly 59 and the chute 57. The springs 58 are perpendicular to the bottom of the scraper assembly 59 and the bottom of the chute 57. The springs 58 are evenly and equidistantly distributed at the bottom of the chute 57. The springs 58 are parallel to each other. When the scraper assembly 59 approaches the conveyor head along with the cleaning plate 56, if there are protrusions or depressions on the surface of the conveyor head, the sliders 510 at both ends of the scraper assembly 59 slide in the chute 57. The springs 58 will expand and contract accordingly according to the pressure changes of the sliders 510, thereby ensuring that the scraper assembly 59 maintains contact with the surface of the conveyor head.

[0032] As a further implementation scheme of the above technical solution: by setting the center points of the central shaft 52 and the rotating shaft 54 ​​to be on the same horizontal line, the rotating shaft 54 ​​is hollow, and the two ends of the return spring 53 are connected to the central shaft 52 and the rotating shaft 54. The return spring 53 is arranged between the central shaft 52 and the rotating shaft 54. The central shaft 52 and the rotating shaft 54 ​​are rotatably connected. When the conveying device 4 vibrates during operation or the surface of the conveyor head is uneven, the rotating plate 55 drives the rotating shaft 54 ​​to rotate relative to the central shaft 52 under the elastic force of the return spring 53, thereby automatically adjusting the angle of the cleaning plate 56;

[0033] As a further implementation scheme of the above technical solution: a number of guide blocks 592 and scrapers 593 are set, the guide block 592 is in the shape of a rectangular parallelepiped, and the vertical cross-section of the scraper 593 is in the shape of a trapezoid. The guide blocks 592 and the scrapers 593 are evenly and equidistantly distributed on the upper end of one of the scraper brackets 591, and the bottom of the guide block 592 is in contact with the hydraulic oil, which ensures that the scraper 593 will not deviate or shake, improves the stability of the scraping action of the scraper 593, and thus more effectively removes the sticky material on the surface of the conveyor head.

[0034] Working process: The cleaning device 5 is connected to the chain on one side of the conveyor 4 through the mounting block 51, so that the cleaning device 5 can move synchronously with the chain of the conveyor 4. When the conveyor 4 is controlled by the drive motor 3 with its own power supply, when the cleaning device 5 is close to the conveyor head, the scraper 593 first contacts the surface of the conveyor head. Since the vertical cross-section of the scraper 593 is a trapezoidal design, its edge can effectively scrape off the sticky material on the surface of the conveyor head. During the scraping process, if the shape of the conveyor head surface changes, such as an arc part, the scraper 593 will move on the scraper bracket 5 through the guide block 592. 91 slides up and down for fine adjustment, and at the same time, it can squeeze the hydraulic oil appropriately, so that one end of the scraper 593 can fit the surface of the conveyor head and adapt to the shape of the conveyor head. The contact between the bottom of the guide block 592 and the hydraulic oil makes the scraper 593 more stable during the sliding process. The hydraulic oil can play a role of buffering and lubrication, reducing the impact force on the scraper 593 when scraping off the sticky material, and extending the service life of the scraper 593. After the scraper 593 scrapes off most of the sticky material, the brush 595 then further cleans the surface of the conveyor head. The arc setting at one end of the brush 595 enables it to The brush 595 can better fit the surface of the conveyor head, especially in some corners or arc transition areas. The brush 595 adapts to the changes in the surface of the conveyor head through the sliding of the guide column 594 in the scraper bracket 591. Similarly, the hydraulic oil at the bottom of the guide column 594 is used to achieve smooth sliding and buffering, effectively sweeping away the fine sticky materials remaining after the scraper 593 scrapes, making the surface of the conveyor head cleaner. If the thickness of the sticky materials is uneven or there is a hard block on the surface of the conveyor head, the rotating plate 55 will rotate appropriately around the central axis 52 under the action of the reset spring 53 and the rotating shaft 54, thereby driving the cleaning The cleaning plate 56 adjusts its angle to ensure the stability of the cleaning plate 56 during the cleaning process and prevents jamming. When the scraper assembly 59 encounters a bump or depression on the surface of the conveyor head during the cleaning process, the sliders 510 at both ends of the scraper assembly 59 slide in the slide groove 57. At the same time, the spring 58 will expand and contract according to the pressure change, so that the scraper assembly 59 can adapt to the height change of the conveyor head surface in the vertical direction, ensuring that the scraper assembly 59 can always maintain appropriate contact pressure with the conveyor head surface, further improving the cleaning effect, and pushing the cleaned sticky material to the next process.
