Description

Technical Field

[0001] The utility model relates to the technical field of coal mine electromechanical transportation, and particularly relates to a coal mine electromechanical transportation transmission device. Background Technique

[0002] Coal mine electromechanical equipment is the basic equipment for the operation of coal mines. During the coal mine collection and production process, a large number of coal mine mechanical equipment, electrical equipment and electromechanical equipment need to be operated, which mainly includes hoisting equipment, ventilation equipment, air compressor equipment, drainage equipment, mining equipment, transportation equipment, etc. The transportation transmission equipment of coal mines is crucial, which is related to the stability and safety of coal mine transportation.

[0003] In the prior art, the Chinese utility model patent with the publication number of "CN220033445U" and the patent name of "A Coal Mine Electromechanical Transportation Transmission Device" discloses a coal mine electromechanical transportation transmission device. The patent records the technical solution that "a scraping component is arranged at the blanking end of the conveyor belt. The scraping component includes a material guiding plate and a roller brush. The roller brush scrapes off the coal slag particles adhered to the conveyor belt to prevent the waste of coal mine resources caused by the adhesion of coal slag particles to the conveyor belt. Then, the scraped coal slag particles are guided outside the electromechanical transportation transmission device through the material guiding plate to prevent the coal slag particles from falling to the bottom of the device and affecting the conveying efficiency. A dust removal component is arranged on the cover plate to treat the coal ash generated during coal mine transportation to prevent the harm to the physical health of workers caused by coal ash."

[0004] However, in the actual use process of this solution, after the roller brush is used for a long time, its bristles will gradually wear. When the roller brush is severely worn, the bristles may not be able to effectively remove the dirt on the conveyor belt, and may even fall off and remain on the conveyor belt during the cleaning process, thus affecting the normal operation of the conveyor belt. When the roller brush can no longer achieve the expected cleaning effect, or there are still obvious stains or impurities remaining on the surface of the conveyor belt after cleaning, then it is necessary to consider replacing the roller brush. However, since the rotating shafts at both ends of the roller brush are usually installed and fixed on the bearing seats, it is necessary to use special tools to disassemble the roller brush, and the operation is relatively cumbersome, which brings inconvenience to the disassembly, installation and replacement operation of the roller brush, and the work efficiency is low.
