Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described:

[0024] Figure 1 to Figure 3 A vibration damping device of an impact ripper is shown, including a ripper beam 1 , a damping material cavity 2 and damping particles 3 . The ripper beam 1 includes a beam middle connecting plate 11, a beam cavity 12 and a beam side end connecting plate 13, the beam cavity 12 is two hollow steel cylinders, and the two hollow steel cylinders are symmetrically arranged on the beam middle connecting plate On the left and right sides of 11, the connecting ends of the two hollow steel cylinders and the middle connecting plate 11 of the beam are closed by welding circular steel plates, and the outer ends of the two hollow steel cylinders are respectively provided with connecting plates at the side ends of the beam 13. The outer end surface of the hollow steel cylinder is open and passes through the connecting plate 13 at the side end of the beam p...

Abstract

The invention relates to a vibration damper of an impact type scarifier. The vibration damper comprises a scarifier cross beam (1), a damping material cavity (2) and damping particles (3). The sealed damping material cavity (2) is formed in a cross beam cavity (12) of the scarifier cross beam (1), and the damping material cavity (2) is filled with the damping particles with a certain particle size. The vibration suppression and damping aim is achieved through multi-direction multi-phase friction, collisions and power consumption between the damping particles and between the particles and the wall of the damping material cavity, and compared with the prior art, the vibration damping effect is better, the vibration influence of the impact type scarifier on the structure and parts of a bulldozer can be effectively reduced, the service life of the bulldozer is prolonged, and the work environment of operation personnel is optimized.

Description

technical field [0001] The invention belongs to the technical field of construction machinery equipment, and in particular relates to a vibration damping device of an impact ripper. Background technique [0002] The impact ripper is the rear working device of the bulldozer, which is widely used in projects such as hard frozen soil, excavation of soil and stone with slabs, and stripping of weathered rock layers. It uses the hydraulic hammer to continuously impact the soil loosening gear rod to break and peel off the high-hardness compacted soil and rocks to improve the working efficiency. Due to the high operating efficiency and economic benefits of the impact ripper, the application of the impact ripper is becoming more and more extensive, but the strong vibration during the working process is likely to cause premature failure of the bulldozer structure and its components, thereby increasing the construction cost. Costs, equipment maintenance costs and worsened the working ...
