[0019] The utility model discloses an automatic clearing device for a belt scale of a clinker line batching station, comprising a bottom plate 8, a scraper 7 and a reciprocating drive assembly. The bottom plate 8 is detachably mounted on the chute of the belt scale head, the bottom plate 8 is close to the chute, the bottom plate 8 is mounted on the surface of the chute, the limestone raw material falls on the bottom plate 8, the scraper 7 is connected to the output end of the reciprocating device, the scraper 7 is close to and slidably arranged on the surface of the bottom plate 8, the reciprocating drive assembly drives the scraper 7 to slide back and forth on the bottom plate 8, and scrapes off the raw materials sticking on the bottom plate 8, thus solving the problem of material blockage at the chute of the belt scale of the clinker line batching station, eliminating the need for manual cleaning of the blockage, reducing labor costs, and ensuring product quality and stable operation of the production process. The device has good blockage removal effect, simple structure, convenient maintenance, and low operating and maintenance costs.

[0020] The following further describes the present utility model in conjunction with specific embodiments. However, those skilled in the art should understand that the detailed description given here in conjunction with the accompanying drawings is for better explanation. The structure of the present utility model necessarily extends beyond these limited embodiments. For some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of this application.

[0021] As Figure 1 described, in this embodiment, a plurality of scraping plates 7 are arranged at intervals in the vertical direction. Each scraping plate 7 is fixedly connected to a connecting plate 12. The short strip-shaped scraping plates 7 are transversely welded to the long strip-shaped connecting plate 12 at intervals in sequence. The output end of the reciprocating driving assembly is connected to the connecting plate 12. A set of reciprocating moving devices drives all the scraping plates 7 to slide up and down along the bottom plate 8 for cleaning. The number of scraping plates 7 is set according to the length of the bottom plate 8.

[0022] In this embodiment, the reciprocating driving assembly includes a motor 1, an eccentric wheel 5 and a connecting rod 6. The eccentric wheel 5 is connected to the output end of the motor 1. One end of the connecting rod 6 is eccentrically and rotatably connected to the eccentric wheel 5, and the other end of the connecting rod 6 is rotatably connected to the scraping plate 7. In order to ensure the stable operation of the device during driving, the motor 1 is bolted to the base 4. A speed reducer is arranged between the motor 1 and the eccentric wheel 5. The motor 1 and the speed reducer are connected by a coupling 2. In this embodiment, the speed reducer adopts a worm gear speed reducer 3. The worm gear speed reducer 3 and the eccentric wheel 5 are connected by a key. The eccentric wheel 5 and the connecting rod 6 are connected by bolts at the joint bearing. The connecting rod 6 is fixedly connected to the connecting plate 12.

[0023] In order to ensure that the scraping plate 7 can scrape off the raw materials adhered to the bottom plate 8, the scraping plate 7 must be tightly pressed against the bottom plate 8. Therefore, a scraping plate pressing member is arranged on the bottom plate 8. The scraping plate pressing member presses tightly on the scraping plate 7, and then the scraping plate 7 is pressed tightly on the bottom plate. Specifically, the scraping plate pressing member includes a pressing rod 9 and mounting blocks 11. The two mounting blocks 11 are respectively arranged on both sides of the scraping plate 7. The mounting blocks 11 are fixedly installed on the bottom plate 8. An installation groove is arranged on the mounting blocks 11. The pressing rod 9 is installed in the installation groove. After the pressing rod 9 is installed in the installation groove, the connecting rod 6 is pressed down, so that the connecting rod 6 and the scraping plate 7 are pressed tightly on the bottom plate.

[0024] As Figure 2 shown, the bottom plate 8 is hung on the chute through a fixing member 10. The fixing member 10 includes a horizontal plate and vertical plates connected to both sides of the horizontal plate. The fixing member 10 is arranged in a "冂" shape. The fixing member 10 is fixedly welded to the upper side of the bottom plate 8, and then is hung on the chute through the fixing member 10. Two rows and two columns of fixing members 10 are welded on the back of the bottom plate 8. A long strip hole is opened at the lower part of the bottom plate 8 and is fixedly connected to the chute through a fixing bolt 13, so that the bottom plate 8 can be firmly挂靠 on the chute to prevent shaking during work.

[0025] When the utility model is in use, the raw material is unloaded from the belt scale, and the device is turned on. When the raw material falls on the bottom plate 8, the high-speed and low-torque force generated by the operation of the motor 1 is transmitted to the worm gear reducer 3 through the coupling 2. Under the conversion of the worm gear reducer 3, this force is converted into a low-speed and high-torque force, thereby driving the eccentric wheel 5 to rotate. The rotational movement of the eccentric wheel 5 further drives each scraper 7 to reciprocate. The lower surface of the scraper 7 and the upper surface of the bottom plate 8 constitute a working surface, so that the raw material on the surface of the bottom plate 8 is continuously cleared during the movement of the scraper 7. The fixing part 10 fixes the bottom plate 8 on the unloading chute and will not deviate during the cleaning process. The pressure rod 9 enables the scraper 7 to be close to the surface of the bottom plate 8, thereby ensuring the cleaning efficiency and then solving the problem of material blockage. The device not only ensures the product quality and the stability of the production process, but also can reduce the labor intensity of personnel and reduce labor costs, thereby improving the quality and efficiency of the entire production operation.

[0026] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
