Abstract

An injection apparatus for treating soil adjacent a structure includes a handle and a manifold head connected to the handle. The manifold head has a first high pressure nozzle, a second high pressure nozzle, and a contact member having at least one opening therein. The contact member is configured to rest on the ground surface during operation of the injection apparatus. The first high pressure nozzle is adapted for emitting a discharge stream of pesticide through the at least one opening in the contact member for injection of the pesticide into the soil. The discharge stream from the first high pressure nozzle is emitted in a first direction. The second high pressure nozzle is adapted for emitting a discharge stream of pesticide through the at least one opening in the contact member for injection of the pesticide into the soil. The discharge stream from the second high pressure nozzle is emitted in a second direction that is angled relative to the first direction of the discharge stream of pesticide emitted from the first high pressure nozzle. A supply of pesticide is in fluid communication with the first and second high pressure nozzles.

Claims

1. An injection apparatus for treating soil adjacent a structure, the apparatus comprising:

a handle;

a manifold head connected to the handle, the manifold head having a first high pressure nozzle, a second high pressure nozzle, and a contact member having a substantially planar contact surface for resting on the ground surface during operation of the injection apparatus, the contact member having a first opening in the contact surface in fluid communication with the first high pressure nozzle and a second opening in the contact surface in fluid communication with the second high pressure nozzle, the first high pressure nozzle being adapted for emitting a discharge stream of pesticide through the first opening in the contact member for injection of the pesticide into the soil, the discharge stream from the first high pressure nozzle being emitted from the first opening in a first direction, the second high pressure nozzle being adapted for emitting a discharge stream of pesticide through the second opening in the contact member for injection of the pesticide into the soil, the discharge stream from the second high pressure nozzle being emitted from the second opening in a second direction that is angled relative to the first direction of the discharge stream of pesticide emitted from the first opening; and

a supply of pesticide in fluid communication with the first and second high pressure nozzles.

2. The injection apparatus as set forth in claim 1 wherein the direction of the discharge stream from the first high pressure nozzle is generally vertically down.

3. The injection apparatus as set forth in claim 1 wherein the direction of the discharge stream from the second high pressure nozzle is angled between about 35 degrees and about 85 degrees relative to the direction of the discharge stream from the first high pressure nozzle.

4. The injection apparatus as set forth in claim 1 wherein the directions of the discharge streams from the first and second high pressure nozzles are predetermined so that when the discharge streams of pesticides are emitted from the first and second openings the discharge streams intersect within the soil.

5. The injection apparatus as set forth in claim 4 wherein the directions of the discharge streams from the first and second openings are predetermined so that the discharge steams intersect each other between approximately 2 inches and approximately 12 inches below a surface of the soil when the discharge steams of pesticides are emitted from the first and second openings.

6. The injection apparatus as set forth in claim 5 wherein the directions of the discharge streams from the first and second openings are predetermined so that the discharge steams intersect each other at approximately 6 inches below the surface of the soil when the discharge steams of pesticides are emitted from the first and second openings.

7. The injection apparatus as set forth in claim 1 wherein the manifold head includes four first high pressure nozzles arranged in spaced relationship with each other.

8. The injection apparatus as set forth in claim 7 wherein the second high pressure nozzle of the manifold head comprises a multiport nozzle.

9. The injection apparatus as set forth in claim 7 wherein the second high pressure nozzle of the manifold head comprises at least one nozzle having a single port.

10. The injection apparatus as set forth in claim 1 wherein the supply of pesticide is disposed on a base unit that is fluidly connected to the manifold head via a flexible conduit.

11. The injection apparatus as set forth in claim 10 wherein the base unit is moveable independent of the handle and manifold.

12. The injection apparatus as set forth in claim 11 wherein the supply of pesticide comprises a supply of insecticide.

13. The injection apparatus as set forth in claim 12 wherein the supply of insecticide comprises a supply of termiticide.

14. An injection apparatus for treating soil adjacent a structure with pesticide, the apparatus comprising a plurality of first high pressure nozzles, a plurality of second high pressure nozzles, and a contact member having a substantially planar contact surface for contacting the soil during operation of the apparatus, the contact member having a plurality of first openings in the contact surface, each first opening being associated with a respective one of the first high pressure nozzles, and a plurality of second openings in the contact surface, each second opening being associated with a respective one of the second high pressure nozzles, the first high pressure nozzles and the respective first openings being configured for emitting respective first discharge streams of pesticide for injection of the pesticide into the soil, the first discharge streams being emitted in a first direction, the second high pressure nozzles and the respective second openings being configured for emitting respective second discharge streams of pesticide into the soil, the second discharge streams being emitted in a second direction that is angled relative to the first direction of the first discharge streams.

15. The injection apparatus as set forth in claim 14 wherein the discharge stream from each of the first high pressure nozzles is emitted generally vertical.
