The invention discloses a novel construction machinery seat suspension device comprising an upper base plate, a lower base plate and an X type mechanism. The upper base plate and the lower base plate are connected through the X type mechanism; the upper base plate is provided with a long shaft revolving around the axis, the middle of the long shaft is provided with two rotating plates, and the other ends of the rotating plates are provided with bearings pressed to the upper base plate; two ends of the long shaft are provided with connecting plates respectively, the connecting plates are provided with short shafts parallel to the long shaft, the short shafts are provided with stretching springs, and the other ends of the stretching springs are fixed to the upper base plate. The device is simple in structure, convenient to operate, the upper base plate is pressed downward, the bearing rotates to drive the rotating plates to rotate so as to drive the stretching springs, owing to the compression of a damper, the weight pressure of a passenger and the device are in a dynamic equilibrium state, the optimal suspension and vibration absorption effects can be achieved, and the optimal comfort is provided for the passenger.
