Problems solved by technology

[0002] When the vibrating screen separates solids, it produces movements in multiple directions, front, back, left, and right. When the vibrating screen is started and closed, due to resonance, the vibration amplitude of the machine will become uncontrollable and become very large, and the distance between the machine and the ground fixed frame The simple spring shock absorber between the screens cannot withstand excessive loads, and will be severely damaged, reducing the service life and further damaging the machine. Therefore, it is necessary to design a shock absorber support for the vibrating screen to solve the above problems

Embodiment Construction

[0015] Combine below Figure 1-7 The present invention is described in detail, and for convenience of description, the orientations mentioned below are now stipulated as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.

[0016] combined with Figure 1-7 The shock absorbing support of a vibrating screen includes a fuselage 90, the fuselage 90 includes a hydraulic chamber 27, the hydraulic chamber 27 contains hydraulic oil 54, and the hydraulic oil 54 in the hydraulic chamber 27 A rubber piston 52 is provided, and a push rod 51 is provided on the rubber piston 52. A rubber sealing bush 50 is provided on the top of the hydraulic chamber 27, and a first opening groove 68 is provided on the rubber sealing bush 50. The push rod 51 can pass through the first opening slot 68 , the top end of the push rod 51 is fixed with a tapered fixing block 11 , and the top plate 10 is fixed on the tapered fixing block 11 ....

Abstract

The invention provides a vibration screen damping support. The support comprises a machine body; the machine body comprises a hydraulic cavity; the hydraulic cavity contains hydraulic oil; a rubber piston is arranged inside the hydraulic cavity above the hydraulic oil; a push rod is arranged on the rubber piston; a rubber sealing lining is arranged at the top of the hydraulic cavity; and a first open groove is formed in the rubber sealing lining. The vibration screen damping support has the beneficial effects that: the structure of equipment is simple and operation is simple and convenient; shock of the equipment in the vertical direction can be reduced via action of the hydraulic cavity; high temperature of the hydraulic cavity caused by reciprocating motion is lowered via circulation ofcooling liquid; connecting rod mechanisms on the left side and the right side of the machine body are matched with air bags, so resonance amplitude of a vibration screen caused during initiation and shutdown is lower; and in an extreme status, the air bags below the machine body enable the machine body to sway, so damage to a hydraulic push rod is avoided. The matching is tight, and the integration degree is relatively high.

Description

technical field [0001] The invention relates to the field of engineering components, in particular to a shock-absorbing support for a vibrating screen. Background technique [0002] When the vibrating screen separates solids, it produces movements in multiple directions, front, back, left, and right. When the vibrating screen is started and closed, due to resonance, the vibration amplitude of the machine will become uncontrollable and become very large, and the distance between the machine and the ground fixed frame The simple spring shock absorber between the vibrating screens cannot withstand excessive loads and will be severely damaged, reducing the service life and further damaging the machine. Therefore, it is necessary to design a shock absorbing support for the vibrating screen to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a shock-absorbing support for a vibrating screen, which is used to overcome t...
