Hydraulic digging apparatus is known and in use. Generally such structures are complex and require varying means for moving the earth or material being worked on away from the digging structure and to remove the same. Borehole diggers similarly are well recognized and take a variety of forms. They are generally mechanical structures with means for lifting the earth or soil to be removed.
The present invention is directed to a simplified borehole digger, such as a post hole digger, of the hydraulic type. it employs a simplified mechanical structure which is well adapted for household and simplified commercial use for the purpose of digging holes, such as fence holes and removing the soil therefrom. It employs a cylindrical structure having a particular annular passage into which water under pressure is directed with a toothed surface at the extremity of the cylindrical structure designed to loosen dirt which will be moved away and raised within an inner cylinder to be disposed of with the water during the digging operation.
It is therefore the object of this invention to provide a simplified post hole digger.
Another object of this invention is to provide a simplified borehole digger of the hydraulic type employing a simplified mechanical structure.
Another object of this invention is to provide a simplified structure of this type utilizing water under pressure for digging and earth removal.
A further object of this invention is to provide a simplified structure of this type which is easy to use and maintain.
These and other objects of this invention will become apparent from the reading of the attached description together with the drawings wherein;
FIG. 1 is a perspective view of my improved post hole digger with parts broken away,
FIG. 2 is a plan view of the post hole digger, and
FIG. 3 is a fragmentary sectional view of the post hole digger of FIG. 1 taken along the lines 3-3 therein.
My hydraulic boring tool or post hole borer is shown in the drawings generally at 10. It incorporates a general cylindrical structure having an outer cylinder member 12 and an inner cylindrical member 14 which are sealed together at the top, as indicated at 15, and at the bottom, as indicated at 16, through the welding of annular flanges thereto. The composite structure will provide an inner and outer cylinder of substantially the same length and with the inner cylinder spaced from the outer cylinder to define an annular area or cylindrical area therebetween. The outer cylinder has connected thereto a pair of handles and 21 which are connected at the top of the outer cylinder and at diametrically opposed points thereto and extending radially therefrom to define a gripping or holding structure for the same. The handle 21 includes a hollow passage 25 therethrough and an on-off shutoff valve positioned in the passage. The latter is connected to a pivoted handie 32 mounted on the handle 21 for the purpose of operating the valve. The passage continues through the wall of the outer cylinder and communicates with the cylindrical area between the cylinder members 12 and 14. The extremity of handle 21 includes a suitable coupling 35 by means of which a hose connection, such as is indicated by 36, may be coupled thereto for the purpose of introducing water under pressure to the passage 25 to be controlled by the 30 and introduced in the annular area between the cylinders 12 and 14.
As will be seen in the plan view, the upper end of the cylinders or the flange 15 covering the same has an arcuate opening positioned therein and communicating with the interior of the inner cylinder and a pipe member is connected to this flange and extends down through the center of the inner cylinder with the pipe member having a removable pipe coupling 52 positioned therein for purposes to be later noted. At the opposite extremity of the hydraulic boring tool, the flange plate 16 connecting the cylinders is inclined and is connected to the cylinders through suitable means such as welding. A plurality of apertures 60 are positioned in this flange member and permit water in the annular area to be directed out from the same in jets of water and toward the center of the inner cylinder. The bottom surface of the outer cylinder is toothed or serrated, as at 70, to define a saw-type surface on the same which will engage the earth and loosen the same as the boring tool is used. The cylindrical pipe member 50 positioned in the center of the inner cylinder is supported by transversely extending flanges 75 near the bottom of the inner cylinder.
in use, my hydraulic boring tool or post hole borer will be connected at the handle 21 to a source of water and the operator or user will position the tool such that the cylinders will define the hole to be bored. By operating the valve 30 through deflection of the handle 32, water under pressure will be introduced into the area between the cylinders and deflected out of the apertures 60 in jets of water on to the earth within the cylinders and below the same. This will erode the soil and the water will carry the soil along with the water up through the interior of the inner cylinder to be discharged out of the aperture 40 in the top flange of the cylindrical structure. The handles permit partial rotation of the cylinder by the operator to cause the toothed surface on the bottom of the same to aid in the removal or loosening of the soil such that when the water under pressure engages the same the loosened soil will be washed toward the center of the cylinder and raised therein to be removed or flow out of the aperture 40 at the top of the same. Through the continuous rotation of the post hole borer and the application of water which may be readily controlled by the operator whose hand is on the handle 21, the entire structure may be forced into the ground to dig or erode a hole in the ground as the material within the cylinders is loosened and raised with the water to be ejected therefrom. This simplified post hole borer permits the householder to readily drill post holes of a uniform size and in varying soil conditions. As the post hole borer is advanced into the earth, that soil which is not completely raised by the water will be retained within the inner cylinder such that upon removal of the post hole borer from a hole the soil will be removed therewith.
A similar application permits the introduction of water at the pipe 50 through the removal of the cap 52, the pipe having an open extremity at the bottom of the same which will provide another source of water under pressure to aid in the removal of the soil therein. The improved post hole borer will have application, depending upon the length of the structure for well drilling and other application.
in considering this invention it should be remembered that the present disclosure is illustrative only and the scope of the invention should be determined by the appended claims.
