ABSTRACT:
Vibrations having a frequency exceeding 150 Hertz are established in a rigid body by means of a vibrator system that in one embodiment includes a pair of rotating wheels, only one of which has a weighted eccentric secured to its axle. The wheels are coupled together by an endless belt made of a material that dampens the vibrations propagating between the wheels. The unweighted wheel is driven by a flexible shaft connected to its axle. In another embodiment three wheels are used in which two are weighted at the axles. The vibrator system may be used to sink pipes and the like into the ground, or snake a sorting table employed, for example, in the mining industry or a silo hopper for discharging grain. Also disclosed is a method for sinking a pipe or the like into the ground and retrieving it after lowering it a predetermined distance. In this method, wires are attached at each end of the pipe for facilitating its downward motion and its retrieval. In another of the embodiments disclosed the vibrator system can rotate as well as simultaneously vibrate pipe into the ground.
