Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a spring support structure for a vibrating screen. Background Technology

[0002] A circular vibrating screen is a high-precision fine powder screening device. It features low noise, high efficiency, and quick screen replacement (3-5 minutes). Its fully enclosed structure makes it suitable for screening and filtering granular, powdery, and viscous materials. The circular vibrating screen uses a vertical motor as its power source, transmitting power to the excitation source via a V-belt. Eccentric weights are installed at the upper and lower ends of the excitation source, converting its rotational motion into a three-dimensional motion (horizontal, vertical, and inclined), which is then transmitted to the screen surface. Adjusting the phase angle at the upper and lower ends can change the material's trajectory on the screen surface. However, currently used circular vibrating screens do not have adjustable bottom springs, which means they cannot provide adequate support when screening materials of varying quality.
