Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaners, in particular to an adjustable conveyor belt cleaner. Background Art

[0002] Coal products are usually transported by conveyor belts. After the transmission, some coal slag will remain on the conveyor belt. When the belt runs to the bottom of the conveyor belt, the coal slag attached to the belt will fall to the ground due to its own gravity, which makes cleaning difficult. In order to facilitate cleaning, a sweeper is installed at the lower end of the conveyor belt to scrape the coal slag attached to the belt running to the bottom to a designated position for collection. The existing sweeper includes a support shaft and a scraper. The support shaft is horizontally connected to the brackets on both sides of the bottom of the conveyor belt. The scraper is fixedly connected to the support shaft, and the coal slag on the belt is scraped off through the top of the scraper. In order to avoid damage to the belt, the scraper is usually made of rubber. However, after a long time of use, some positions of the rubber scraper, especially the middle position, will gradually collapse downward due to the effect of its own gravity, so that the middle position of the scraper cannot contact the belt surface, and thus the coal slag on the belt cannot be scraped off. In addition, the extension length of the scraper of the existing sweeper cannot be adjusted, and the degree of closeness between the scraper and the belt cannot be adjusted according to actual use.
