Vibratory plow assembly

Abstract

A vibratory plow assembly 201 incorporates a vertical ground parting blade 202 with a front cutting edge 203 and a ripper tooth 208. The blade 202 is bifurcated rearwardly of the cutting edge 203, the blade 202 being formed by two spaced-apart side plates 214. The upper part of the plates 214 constitute a support frame which is pivotally connected by a pin 205 to a base plate 240. Attached rearwardly of the pivot pin 205 and preferably cantilevered beyond the plates 214 is a vibrator unit 232. The vibrator unit 232 when operational provides a vibratory frequency of between 5 Hz and 17 Hz to the ripper tooth 208 in both a vertical and arcuate path. The pivot pin 205 is preferably located above or forwardly of the cutting edge 203. The base plate 240 and support frame, by virtue of the vibratory unit 232, experience relative movement in the manner of a pair of jaws the mouth of which extends rearwardly. Buffers 252 located between the base plate 240 and the support frame tend to bias the jaws into an open condition. A mounting means 400 enables the assembly 201 to be attached to a tractor vehicle so that in use, a trench is dug by the assembly 201 and cable, which passes from a forward position to a rearward position via cable guides 215 located between the plates 214, can be laid.
