Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, and more specifically, to an adjustable vibrating screen. Background Art

[0002] Vibrating screen is a separation device used to screen materials. In large-scale industrial production processes, vibrating screens are often used to separate particles of different sizes, densities or shapes in the material in order to classify the material or screen out impurities inside it.

[0003] During use, the existing vibrating screens are not convenient for scraping away the material particles accumulated in the sieve holes on the screen, which easily causes the materials to clog the sieve holes and affect the screening efficiency. When pouring materials, the materials are easily piled up and the materials cannot be evenly distributed on the screen, which greatly affects the screening efficiency. Moreover, the screens of the existing vibrating screens are fixed on the screens by bolts. When the mesh size of the screens needs to be adjusted, it is not convenient to quickly replace the screens. At the same time, after the materials are screened, some larger materials will accumulate on the surface of the screens, which requires manual cleaning regularly, which not only consumes a lot of labor but also has low cleaning efficiency.
