Abstract
A vibratory plow suitable for laying flexible cable, pipe and the like underground. The vibratory plow assembly includes a frame which supports the assembly on a tractor, bulldozer or other vehicle, a vibrator and a plow. The vibrator includes a housing and a rotating eccentric weight assembly which imparts an oscillatory motion to the vibrator housing about a neutral axis having a varying and reversing moment. The vibrator is supported on the frame by resilient bearings in the neutral axis of the vibrator and the plow is supported on the vibrator housing spaced from the neutral axis to impart vertical vibration to the blade. The first embodiment includes a blade on each side of the neutral axis, such that the blades are vibrated in opposite directions to impart a shearing action. In the second embodiment, only one blade is utilized and a counterweight is supported on the vibrator housing to counterbalance the blade. The preferred embodiment of the vibrator utilizes two weights rotating in the same direction 180 degrees out of phase and a pair of amplitude adjustment weights supported on the vibrator housing equidistant from the neutral axis.
