Description

Technical Field

[0001] The utility model belongs to the technical field of belt feeders, in particular to a belt feeder. Background Art

[0002] A feeder is a device used to transport materials from storage equipment (such as silos, hoppers) to downstream processing equipment (such as crushers, grinders, mixers, etc.). A belt feeder is a type of feeder, that is, a belt conveyor, which uses a continuously moving belt to transport materials from the feed end to the discharge end.

[0003] When wet sand is conveyed by a belt feeder, because the wet sand has a certain viscosity, a part of the wet sand will remain on the belt during the conveying process. Generally, a scraper plate is installed on the belt feeder to scrape off the residual wet sand on the belt, thereby improving the accuracy of wet sand weighing.

[0004] However, after the scraper plate is installed on the feeder, the scraper plate is generally brought into contact with the belt through a spring member to achieve the effect of scraping sand. However, when the spring force is small, the contact force between the scraper plate and the belt is small, and it cannot be guaranteed that the residual wet sand can be scraped off cleanly. When the spring force is large, the contact force between the scraper plate and the belt is large, which will cause certain damage to the belt. Therefore, a belt feeder is proposed to address the above problems. Utility Model Content
