Abstract
A fluid assisted wedging and compacting device for the installation of underground cable that includes a blade with a cutting edge, two cutting faces a toe, a shoe, a cable feed tube, a pair of deflectors, a pair of grooves and a plurality of high pressure water jet nozzles. The blade is designed so that the deflectors and grooves are positioned in a vertical orientation on the lower half of the cutting faces of the blade. During use, the deflectors on the cutting faces deflect soil creating a soil free zone preventing blockage of the nozzles and allowing the water pressure from the nozzles to effectively aid the blade in cutting through the soil.
Claims22
A ground wedging device, comprising:
- a generally vertical main body portion having a blade along the forward edge;
- said blade including a cutting face;
- a cutting edge adjacent to said cutting face;
- a substantially vertical deflector rib extending from and along said cutting face;
- a plurality of nozzles positioned on said cutting face behind said deflector rib, adapted to expel a liquid outwardly from said cutting face;
- whereby said liquid expelled from said plurality of nozzles enhances the ability of said ground wedging device to cut through the ground.
A soil wedging device, comprising:
- a blade;
- a first cutting face and a second cutting face formed on a front surface of said blade;
- a cutting edge formed by the intersection of said first cutting face and said second cutting face;
- a first substantially vertical deflector rib extending from and along said first cutting face;
- a second deflector extending from and along said second cutting face;
- and
- a plurality of nozzles positioned on said first cutting face and said second cutting face behind said deflector ribs, adapted to expel a liquid outwardly from said first cutting face and said second cutting face.
A ground wedging device, comprising:
- a blade;
- a cutting face formed on a front surface of said blade;
- a cutting edge formed by the intersection of said cutting face on a side surface;
- a substantially vertical deflector rib extending from and along said cutting face;
- at least one nozzle positioned on said cutting face behind said deflector rib, adapted to expel a liquid outwardly from said cutting face;
- whereby said liquid expelled from said at least one nozzle enhances the ability of said ground trenching apparatus to cut through the ground.
A soil wedging device, comprising:
- a blade;
- a first cutting face and a second cutting face formed on a front surface of said blade;
- a cutting edge formed by the intersection of said first cutting face and said second cutting face;
- a first deflector extending from said first cutting face;
- a second deflector extending from said second cutting face;
- and
- a plurality of nozzles positioned on said cutting faces, adapted to expel a liquid outwardly from said cutting faces;
- said blade further including outwardly extending wedges, wherein said wedges include a nozzle for expelling a liquid under pressure.
A ground wedging device, comprising:
- a blade
- a cutting face formed on a front surface of said blade;
- a cutting edge formed by the intersection of said cutting face on a side surface;
- a deflector extending from said cutting face;
- at least one nozzle positioned on said cutting face, adapted to expel a liquid outwardly from said cutting face;
- a wedge extending outwardly from said side surface of said blade, said wedge including a wedging face, wherein said wedging face includes at least one nozzle.
