Abstract

Apparatus for injecting a fluid below a soil or turf surface includes a handle with a support rod attached thereto, and a plurality of nozzles carried by the support rod, each nozzle forming a stream of fluid passing therethrough. Each nozzle is provided with a skid having a curved surface for low friction contact with the soil or turf surface and for holding the nozzle out of contact with the surface. The apparatus is provided with a pump which cooperates with the nozzle to inject the fluid substantially below the soil surface.

Claims

1. Apparatus for injecting a fluid below a soil surface comprising:

an oblong hollow tube member;

a hollow support rod extending substantially normal to said tube member;

a plurality of nozzles carried by said support rod, each said nozzle capable of forming a stream of said fluid passing therethrough;

said tube member communicating with said rod and said rod communicating with all of said nozzles;

a plurality of spaced, individual skids of generally elliptical cross-section, each positioned adjacent one of said nozzles for providing a low friction contact with said soil surface and for engaging said soil surface to hold said nozzles out of contact with said soil surface, each skid having an aperture therethrough axial with the corresponding one of said nozzles;

means for pumping fluid through said nozzle under pressure; and

wherein

said pumping means and said nozzles cooperate to inject said fluid substantially below said soil surface.

2. The apparatus recited in claim 1 wherein the major and minor axis of all of said skids lie in a plane which is transverse to said support rod.

3. The apparatus recited in claim 1 wherein each said nozzle includes means for defining a relatively narrow fluid stream therefrom, said stream having a cross-sectional dimension not greater than the cross-sectional dimension of the aperture of said nozzle so as to facilitate injection of said fluid below said soil surface.

4. The apparatus recited in claim 3 wherein said fluid stream defining means comprises a baffle within said nozzle.

5. The apparatus recited in claim 4 wherein said baffle comprises an oblong member in each said nozzle and extending substantially parallel with the direction of fluid flow.

6. The apparatus recited in claim 5 further comprising a valve along said tube for controlling flow of fluid therethrough.

7. The apparatus recited in claim 6 further comprising a filter positioned between said valve and said support rod for removing foreign substances from said fluid.

8. The apparatus recited in claim 1 further comprising means for adjusting the angle between the axes of said skids and said support rod.

9. The apparatus recited in claim 8 wherein said adjusting means comprises:

a strut carrying each said skid, each pivotably joined to the corresponding strut; and

means for locking each skid in a desired position with respect to the corresponding strut.

10. The apparatus recited in claim 9 further comprising means for adjusting the length of said support rod.

11. The apparatus recited in claim 10 further comprising means for adjusting the dimension between said support rod and each said strut.
