Description

Scraper device of belt conveyor

Technical Field

The utility model relates to the field of belt conveying equipment, in particular to a scraper device of a belt conveyor.

Background

The function of the sweeper is to remove adhering material from the conveyor belt and to deposit such material in the discharge zone. If the materials which are not cleaned and adhered on the conveyer belt are collided when passing through the return idler, a large amount of materials can be accumulated quickly, and even the return conveyer belt is contacted to cause shutdown accidents. Meanwhile, the materials are carried to the return section, so that the conveyor belt can be worn strongly, scale is formed on the lower carrier roller, and the conveyor belt is deviated.

The cleaner has various forms, such as a scraper type, a roller type, a brush type, a pneumatic type, a comprehensive type and the like, wherein the cleaner which is suitable for cleaning the loose materials with low belt speed and weak viscosity is mainly a scraper type cleaner. The working mechanism of the existing scraper type sweeper mainly adopts a metal scraper, an elastic scraper or a plastic scraper. After the sweepers are actually used for a period of time, the sweepers often work unstably due to the reasons of deformation, abrasion and the like of the scrapers, and the upper and lower intervals of the sweepers need to be manually and repeatedly adjusted at intervals to ensure that the contact area between the sweeper scrapers and a conveyor belt reaches the normal use requirement of more than or equal to 75 percent, such as the Chinese patent application (issued patent number: CN113511483A name: a belt conveyor scraper device).
