RIPPER WITH DYNAMIC VIBRATION ABSORBER

摘要

A ripper with dynamic vibration absorber is a basic traction machine behind which bearing frame is installed, to that one through the upper draft frame and the lower draft frame a module of the ripping angle change is fixed pivotally. Besides that between the bearing frame and the module for change of the ripping angle a lift hydro-cylinder is installed pivotally. A working beam with a tooth is fixed to the module of the ripping angle change through vibration absorber, the upper section of the module of ripping angle change and the working beam are connected with hydro-cylinder of ripping angle change. The vibration absorber comprises a body where a rod with a piston are placed, the piston includes a permanent magnet, and the piston is arranged with throttling openings with diameter d arranged in circle with diameter D, and Dd. In the rod cavity a rod washer is fixed on the rod at distance L, between the piston and rod washer the rod a shutoff valve is placed with possibility of free motion, its thickness is 1, at that L1, with diameter D, and DD+d.
