Embodiment
The technical solution of this patent is described in more detail with reference to embodiment.
Please refer to Fig.1-2, a kind of dual vibration damper for agricultural machinery, including base 1, damping device 2, main damping
Chamber 3, damping spring 4, piston A5, piston rod A6, top board 7, stomata 8, ventilation passage 9, piston rod B10, auxiliary damping chamber 11,
Piston B12, upper magnet 13 and lower magnet 14, are welded and fixed on the base 1 and are provided with damping device 2, in 2 inside of damping device
Heart position is provided with main damping chamber 3, and main 3 internal slide of damping chamber is provided with piston A5, on the downside of piston A5 with main 3 bottom of damping chamber it
Between be connected with damping spring 4, be provided with some groups of stomatas 8 at left and right sides of main 3 lower part of damping chamber, stomata 8 is circular through hole
And be placed equidistant between each group stomata 8, ventilation passage 9 is also provided with the damping device 2, ventilation 9 side of passage connects with stomata 8
Logical, ventilation 9 opposite side of passage is in communication with the outside, and is welded with piston rod A6 on the upside of the piston A5, piston rod A6 straight up and
It is slidably connected between 2 shell of damping device, top board 7 is fixedly connected with by screw on the piston rod A6, under top board 7
Side is also mounted by means of screws with piston rod B10, and piston rod B10 is located at the left and right sides of piston rod A6, the damping respectively
