Abstract
A depth vibrator for compacting soil, comprising a rotary drive (); a drive shaft (), which is rotatingly drivable about a rotary axis (A) by the rotary drive () in a first rotation direction (R) and in an opposite second rotation direction (R); a primary mass body () connected non-rotatably to the drive shaft () and rotates together with the latter about the rotary axis (A); a secondary mass body (), which is movable into a first rotation position (P) relative to the primary mass body () by rotation of the drive shaft () in the first rotation direction (R) and which is movable into a second rotation position (P) by rotation of the drive shaft () in the second rotation direction (R). In the first and second rotation position (P) the secondary mass body () can be rotated together with the primary mass body () about the rotary axis (A); and the center of mass (S) of the secondary mass body () and the center of mass (S) of the primary mass body () have different radial distances from the rotary axis (A).
