Abstract

An earth compactor having a unitary base with downwardly facing convex surfaces. A first vibrator assembly is mounted generally centrally of one surface and a second vibrator assembly is mounted generally centrally of the second surface. Each assembly includes an eccentrically mounted weight. The weights are rotated at a speed ratio of 2:1 relative to each other and are initially positioned so both weights are up relative to the shafts on which they rotate. Such phasing of the weights provides an upwardly directed simultaneous unweighting action which facilitates steering and moving the machine by an operator. In one embodiment the weights have the same mass. The impacts exerted on the earth by this machine have a complex waveform, including a band of frequencies which provide for optimum compacting of earth of various particle sizes and consistencies. In a second embodiment the slower rotating weight has a greater mass than the faster rotating weight. In another embodiment, the portion of the base associated with the slower rotating heavier weight is heavier than the portion of the base associated with the lighter faster rotating weight.
