AI Technical Summary
Traditional vibrating screens lack a guiding structure in their spring mechanism, resulting in scattered and disordered vibration direction, which affects screening efficiency.
Design a suspended spring vibration mechanism, which uses components such as a central guide sleeve, a central guide rod, an outer peripheral guide sleeve, and a guide rod. The multi-point guiding structure ensures that the vibration direction is along the axial direction, and the angular momentum is limited by the convex line and gears to avoid radial deviation.
This achieves micro-vibration of the vibrating screen strictly along the axial direction, improving screening efficiency and equipment operation stability.

Technical Field
[0001] This utility model relates to the field of vibrating screen technology, specifically a suspended spring vibration mechanism for vibrating screens. Background Technology
[0002] A vibrating screen is a mechanical device that uses vibration to screen, classify, dewater, or separate materials. The main components of a vibrating screen include the screen box, vibrator, spring mechanism, support frame, and transmission mechanism. Among these, the vibrator and spring mechanism are the core components; the former generates mechanical vibration, while the latter amplifies the amplitude. Both have a crucial impact on the performance of the vibrating screen, especially its screening efficiency. Traditionally, the springs in a vibrating screen are directly connected between the base frame and the screen box, achieving support through multi-point installation. This type of spring mechanism has the advantages of low cost and simple structure, but due to the lack of a guiding structure, its micro-vibration direction is scattered and disordered.
