Description

Technical Field

[0001] This application relates to the technical field of vibrating screens, and particularly to a vibrating screen. Background Art

[0002] In the screening operation of solid particulate matter, the vibrating screen is one of the widely used devices. Among them, the circular vibrating screen plays an important role in the screening process due to its characteristics of moving up and down. However, this movement mode easily causes the material to rise and generate dust dispersion, seriously polluting the environment. Traditional vibrating screen designs often have defects. Either there is no equipped cover plate, or the cover plate is directly connected to the vibrating screen body through fastening bolts. Due to the action of inertial force during the vibration process, a strong interaction force is generated between the cover plate and the vibrating screen. Even if self-locking bolts are used for fixation, cracks often appear on the cover plate within less than one month of use. These cracks will further exacerbate the interaction force between the cover plate and the vibrating screen, resulting in the expansion of the cracks, forming a vicious cycle, and thus accelerating the damage of the cover plate. Frequent replacement of the damaged cover plate not only consumes a large amount of manpower, material resources and financial resources, but also requires the system to stop for each replacement, seriously affecting the continuity and stability of production. Utility Model Content
