SYSTEM AND METHOD TO EXCAVATE USING VACUUM EXCAVATOR
A system and method to excavate using a vacuum hose is disclosed. The system includes a suction wand handle, where a first end of the suction wand handle is adapted to be secured to a suction hose and a first and second grip project from opposing sides of the suction wand handle are adapted for a user to grasp. In addition, a suction wand is secured to a second end of the suction wand handle, where the suction wand includes an open end. An air line is secured to the suction wand, where a first end of the air line is adapted to be in communication with a pressurized air source and the second end terminates in at least one air nozzle at the open end of the suction wand.
1 . A system to excavate using a vacuum excavator, the system comprising:
a suction wand handle, wherein a first end of the suction wand handle adapted to be secured to a suction hose;
a first and second grip projecting from opposing sides of the suction wand handle and adapted for a user to grasp;
a suction wand secured to a second end of the suction wand handle, wherein the suction wand having an open end; and
an air line secured to the suction wand, wherein a first end of the air line is adapted to be in communication with a pressurized air source and the second end terminates in at least one air nozzle at the open end of the suction wand.
2 . The system of claim 1 , further comprising a water line secured to the suction wand, wherein a first end of the water line is adapted to be in communication with a pressurized water source and the second end terminates in at least one water nozzle at the open end of the suction wand.
3 . The system of claim 2 , wherein the at least one water nozzle, air nozzle, or any combination thereof, generates a dynamic spray pattern.
4 . The system of claim 3 , further comprising a valve to intermittently allow a flow to the at least one water nozzle, air nozzle, or any combination thereof, causing the flow to pulsate.
5 . The system of claim 4 , wherein the suction wand further comprising an upper portion and an angled lower portion to the open end.
6 . The system of claim 5 , wherein the angled lower portion is adapted to rotate manually or automatically causing the open end to track in a circular motion covering an area larger than a diameter of the suction wand.
7 . The system of claim 6 , further comprising a motor causing the angled lower portion to rotate about the upper portion of the suction wand when the motor is activated.
8 . The system of claim 7 , further comprising a rod connecting the motor to the angled lower portion.
9 . The system of claim 8 , wherein the angled lower portion is a flexible hose structurally supported by the rod.
10 . The system of claim 1 , wherein the air line is secured to an interior portion or exterior portion of a sidewall of the suction wand from a top portion to a lower portion of the suction wand.
11 . The system of claim 2 , wherein the water line is secured to an interior portion or exterior portion of a sidewall of the suction wand from a top portion to a lower portion of the suction wand.
12 . A system to excavate using a vacuum excavator, the system comprising:
a suction wand, wherein a first end of the suction wand adapted to be secured to a suction hose and a second end of the suction wand having an open end; and
an air line secured to the suction wand, wherein a first end of the air line is adapted to be in communication with a pressurized air source and the second end terminates in at least one air nozzle at the open end of the suction wand.
13 . The system of claim 12 , further comprising a water line secured to the suction wand, wherein a first end of the water line is adapted to be in communication with a pressurized air source and the second end terminates in at least one water nozzle at the open end of the suction wand.
14 . A method to excavate using a vacuum excavator, the method comprising:
grasping an elongated suction wand, wherein a first end of the suction wand is secured to a suction hose and a second end of the suction wand being open;
placing downward force on the suction wand to excavate material from a hole using suction from the suction hose; and
directing pressurized air adjacent to an open end of the suction wand to loosen material.
15 . The method of claim 14 , further comprising rotating the pressurized air, pressurized water, or any combination thereof, when discharged at the open end of the suction wand to generate a dynamic spray pattern.
16 . The method of claim 14 , further comprising pulsating a flow of pressurized air, pressurized water, or any combination thereof, when discharged at the open end of the suction wand.
17 . The method of claim 14 , further comprising rotating an angled lower portion of the suction wand in a circular motion to cover an area larger than a diameter of the suction wand.
18 . The method of claim 14 , wherein the flow of pressurized air, pressurized water, or any combination thereof, is discharged adjacent to the open end of the suction wand.
19 . The method of claim 14 , wherein the water line is secured to an interior portion or exterior portion of a sidewall of the suction wand from a top portion to a lower portion of the suction wand and within a diameter of the suction wand.
20 . The method of claim 17 , wherein the angled lower portion of the suction wand is comprised of flexible hose.
