Problems solved by technology
[0002] At present, the vibration isolators used in vibrating screens are mainly metal cylindrical helical springs, which cannot provide damping
Therefore, when the vibrating screen passes through the resonance zone during the start or stop process, the amplitude of the vibrating screen is relatively large, which affects the life of the vibrating screen parts and the stability of the foundation.
For this reason, the manufacturer must take other methods to suppress the vibration amplitude, which makes the cost of the vibrating screen high; the vibration isolator used in the vibrating screen also uses rubber cylinders as the vibration isolator, but the damping it can provide is limited when the vibrating screen resonates. And when the vibrating screen is working normally, it provides a large damping energy consumption, so the rubber cylindrical vibration isolator is not used much

Embodiment Construction
[0010] The detailed structure of the present invention is described in conjunction with specific embodiments.
[0011] like figure 1 As shown, the shock absorber includes a conical composite spring shock absorber, a rubber rod ring shock absorber, a top 3 cover and a bottom plate 14. The conical composite spring shock absorber is a conical hollow cylindrical structure, and the rubber rod ring shock absorber is placed Inside the conical composite spring shock absorber; the conical composite spring shock absorber includes metal conical coil spring 6 and rubber conical coil spring 5; 5 is fixed on the top cover 3 and the bottom plate 14 by the second screw 4, and the rubber rod ring shock absorber includes a cylindrical rubber shock absorber 1, a circular rubber shock absorber ring 9, a circular metal upper baffle 7, a circular Annular metal lower baffle 11 and metal cylinder 13; wherein the cylindrical rubber damping rod 1 is fixed under the top cover 3 through the first screw ...

The invention relates to a duplex-damping coupling absorber. The absorber comprises a circular cone compound spring absorber body, a rubber rod ring absorber body, a top cover and a base plate, wherein the circular cone compound spring absorber body is of a circular cone type cylindrical structure, the top cover is arranged at the upper end of the circular cone compound spring absorber body, the base plate is arranged at the lower end of the circular cone compound spring absorber body, and the rubber rod ring absorber body is arranged inside the circular cone compound spring absorber body and fixed below the top cover. The duplex-damping coupling absorber has the advantages that a metal cylindrical spiral spring or a cylindrical rubber spring in the prior art is changed into a novel absorber, namely the duplex-damping coupling absorber; the duplex-damping coupling absorber is formed by coupling the circular cone compound spring absorber body and the rubber rod ring absorber body which are formed by vulcanizing a metal circular cone spiral spring and a rubber circular cone spiral spring in a compounded mode. By means of the duplex-damping coupling absorber, only small damping can be provided when a vibrating screen normally works, large damping can be provided when a car passes through a resonance area during starting or parking, and the duplex-damping coupling absorber is a relatively-ideal absorber.
