It is set with the first axle sleeve in the outer circle of pressure spring, the first nut is equipped with by screw thread in the installation axle of the first above axle sleeve, the
One axle sleeve is fixed on the upper end of the first pressure spring by the first nut, and the second pressure spring is set in the installation axle of reticle bottom,
It is set with the second axle sleeve in the installation axle of the second pressure spring bottom, is equipped in the installation axle of the second axle sleeve bottom by screw thread
4th nut, the second axle sleeve are fixed on the bottom of the second pressure spring by the 4th nut.
Further, it is provided with screw thread in the outer circle of first axle sleeve, is set with second on first axle set by screw thread
Nut and third nut.
Further, first pressure spring and the second pressure spring use different spring constants.
Further, the reticle is manufactured using rubber material.
Further, for first pressure spring in when killing state, appointing between the first axle sleeve and reticle has gap.
Compared with prior art, the invention has the following advantages:
The damper mechanism through the invention, is provided with screw thread in the upper and lower ends of installation axle, is set in installation axle
There is reticle, the first pressure spring is set in the installation axle above reticle, is set with first axle in the outer circle of the first pressure spring
Set, is equipped with the first nut by screw thread in the installation axle of the first above axle sleeve, the first axle sleeve is fixed on by the first nut
The upper end of first pressure spring is set with the second pressure spring in the installation axle of reticle bottom, in the installation axle of the second pressure spring bottom
It is set with the second axle sleeve, the 4th nut is equipped with by screw thread in the installation axle of the second axle sleeve bottom, the second axle sleeve passes through the
Four nuts are fixed on the bottom of the second pressure spring.This technology mainly reduces the effect of vibration power of screening installation by secondary vibration damping,
First time vibration damping is the reticle by rubber material, is that the transmitting of vibration is reduced by the first pressure spring for the second time, while can
With by adjust the first axle sleeve to the clamping force of the first pressure spring, by the second axle sleeve to the clamping force of the second pressure spring come
Change the amplitude of the first pressure spring and the second pressure spring, to reduce the active force of vibration, plays the effect of vibration damping.
