Further, each hollow cylinder internal cavities is mounted with the damping material chamber (2) of 4 cylinder-like structures; Damping material chamber (2) adopts thin-wall steel tube to make, and with damping particles (3), fills after internal cavities closed at both ends; Hollow cylinder is made by steel pipe.
The vibration damping equipment of this impact type ridge buster has following beneficial effect:
(1) in the present invention, in the crossbeam cavity of ridge buster crossbeam, be provided with damping particles, when vibrating, understands by impact type ridge buster the friction that produces multi-direction leggy between damping particles and between damping particles and chamber, damping material chamber wall, collision and power consumption, thereby the decay that suppresses impact type ridge buster vibration amplitude and accelerate to vibrate, but reach the object of the vibration damping that shakes, compare and there is good damping result with existing structure, can effectively reduce the influence of vibration of impact type ridge buster to bulldozer, improve the working life of bulldozer structure and component, Optimum Operation personnel's working environment.
(2) in the present invention, in each damping material chamber, the fill factor of damping particles is 20% to 30%, and damping particles is selected
extremely
steel ball, make between Buddhist nun's particle and damping particles and chamber, damping material chamber wall between friction, collision and the energy consumption effect of the multi-direction leggy that produces reached the best.
(3) in the present invention, damping material chamber be arranged in crossbeam cavity and between two tangent being in contact with one another carry out radial location, position structure is simple and practical, has reduced construction cost and manufacture cost.
(4) the present invention is simple in structure, cost is lower, good damping result, good in economic efficiency, be easy to promote.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
Fig. 1 shows a kind of vibration damping equipment of impact type ridge buster to Fig. 3, comprise ridge buster crossbeam 1, damping material chamber 2 and damping particles 3.Ridge buster crossbeam 1 comprises crossbeam middle connecting plate 11, crossbeam cavity 12 and crossbeam side connecting plate 13, crossbeam cavity 12 is two hollow steel drums, two hollow steel cylinder-symmetrical are arranged in the left and right sides of crossbeam middle connecting plate 11, the connecting end of these two hollow steel drums and crossbeam middle connecting plate 11 seals by welding circular steel plate, and the outer end of these two hollow steel drums is respectively arranged with crossbeam side connecting plate 13.The crossbeam side connecting plate 13 that is arranged on this end is opened wide and passed in the exterior edge face of hollow steel drum, and each hollow steel cylinder interior cavity is settled four cylindrical damping material chambeies 2, and damping material chamber 2 is tangent between two, is in contact with one another to carry out radial location.Thereby damping material chamber 2 is connected and carries out axially locating with crossbeam cavity 12 by the mode of spot welding.Damping material chamber 2 adopts thin-wall steel tubes to make, and with damping particles 3, fills after internal cavities closed at both ends, prevents that particle from leaking outside.Damping particles 3 is selected
