Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to an adjustable elastic structure of a vibrating screen equipment. Background Art

[0002] The sediment vibrating screen uses a vibration motor as a vibration source to throw the sediment on the screen and move forward in a straight line. The sediment enters the feed port of the screening machine evenly from the feeder, and passes through multiple layers of screens to produce several specifications of oversize and undersize, which are discharged from their respective outlets.

[0003] For example, a sediment vibrating screen with the Chinese patent document announcement number CN220329252U includes a frame 1, a screen body 2, an elastic mechanism 3, a screen mesh 5, a fixing mechanism 6 and a limit assembly. The elastic mechanism 3 includes a connecting block 301 and a vibration isolation spring 302. The connecting block 301 is fixedly mounted on one end of the outer side of the screen body 2. The connecting block 301 is provided with four groups. The bottoms of the four groups of connecting blocks 301 are all fixedly mounted with vibration isolation springs 302. One end of the four groups of vibration isolation springs 302 is fixedly mounted on the tops of the four corners of the frame 1. This structure is achieved through the matching of the connecting block 301 and the vibration isolation spring 302. When used together, it can play a buffering role during the operation of the screen body 2, so that the sediment can move forward on the screen mesh 5 without damaging the vibrating screen. It can also support the screen body 2 so that the screen body 2 can achieve the required vibration and reduce the dynamic load transmitted to the frame 1, so that the frame 1 can be stably fixed to the ground; but there is a disadvantage: when the elastic mechanism is used for a long time under high load, since the fatigue life of the spring is not necessarily consistent, after individual springs gradually soften, the screening device will be unevenly stressed, which may cause unexpected movement of the vibrating screen mesh, resulting in poor screening efficiency and effect of the screen mesh.
