Abstract
A plow blade having a fluid passageway and points of fluid ejection is produced with basic manufacturing processes allowing for efficient production. The blade construction has a multiple component assembly for providing the ability to rebuild a blade and replacing a portion of the blade that may be worn. In another aspect of the invention a process of ejecting a specific fluid at specific points along a plow blade the desirable characteristics are maximized, while the volume of ejected fluid is minimized. This method is adaptable in static plowing and vibratory plowing utilities since lubricating the sides of the blade/chute that come into contact with the ground with fluid has been found to greatly reduce the amount of drag (friction).
Description
- This application is a divisional of and claims the benefit of U.S. patent application Ser. No. 10/396,619, filed Mar. 25, 2003, entitled “PLOW BLADE WITH WATER PASSAGEWAY.”
- Not Applicable
- Many types of services are delivered to homes through conduits installed in relatively shallow underground trenches. These include telephone, television, natural gas, electricity, and drainage. These utilities are often installed with a plow.
FIG. 1 illustrates an example installation of autility 20 with a prior art plowing process. Aplow 30 is attached to a prime mover, typically atractor 10. Thetractor 10 propels the plow through the ground. Theplow 10 is relatively narrow and will split the ground open with a sharpened steel blade. Theutility line 20 is introduced into the ground through achute 40 that is attached to and directly behind the blade. Thechute 40 holds the ground open as theutility line 20 is being fed into the desired vertical position and places theutility line 20 into a horizontal position at the desired depth under ground. - An alternate configuration is illustrated in
FIG. 2 where theutility line 20 is laid out on the ground behind its intended position and then theplow 30 is connected to one end. The plow is then pulled through the ground in order to pull theutility line 20 into the correct position. In this configuration there is no chute. - Depending on the desired depth, size of utility line, and the ground (soil) conditions (clay, sand, loam, etc.). This process may be slow and require a large amount of power from the
tractor 10 to pull the blade/chute through the ground. To reduce this loading various efforts have been made to inject liquid to the plow and to the utility being installed to wet the ground. - In some past designs the liquid was water, ejected in the direction of travel of the plow blade, and at the edge of the plow blade, utilizing the water to assist in the cutting action required to slice the ground.
- In other designs, useful for applications as illustrated in
FIG. 2 , the liquid has been water directed to the area around the utility line being pulled through the ground to lubricate and reduce the frictional drag. - In still other designs water has been directed through
long holes 36 drilled into theblade 34 of theplow 30. Additional cross-drilled holes threaded to accept cooperatingnozzles 38 are drilled nearfront edge 32, as illustrated inFIGS. 3 and 4 . Water was then pumped into inlet fitting 37 to route water to the sides of the plow. This design has proven successful as the lubrication provided by the water significantly reduces the power necessary to pull the plow. However this requires complicated manufacturing processes, with the result that a wear item, the blade, becomes a relatively expensive component. There exists a need for a blade to provide this water distribution in a manner, that is less expensive to initially manufacture and to maintain. - The present invention relates to a novel design for a plow blade which provides a fluid passage and points of fluid ejection which is produced with basic manufacturing processes allowing efficient production.
- Another aspect of the present invention is a blade construction including a multiple component assembly. This provides the ability to rebuild a blade, replacing a portion of the blade that may be worn.
- In another aspect of the present invention a process of ejecting a specific fluid at specific points along a plow blade the desirable characteristics are maximized, while the volume of ejected fluid is minimized. This method is adaptable in static plowing and vibratory plowing utilities. Lubricating the sides of the blade/chute that come into contact with the ground with fluid has been found to greatly reduce the amount of drag (friction).

FIG. 5 illustrates aplow 100 constructed according to the principles of the present invention.Plow 100 consists ofblade 110, leadingedge sections 120,point 130 and afluid tube 140.Chute 40 is attached to therear edge 114 ofblade 110, and is constructed to receive and guideutility line 20 from above the ground to the desired depth where it is oriented generally parallel to the ground surface. In other embodiments, the chute may be replaced by a puller adapted to hold a utility line that is being pulled through the ground, similar to the arrangement shown inFIG. 2 . - The
blade 110 further includes afront edge 112, atop end 116 and abottom end 118. Thetop end 116 includesapertures 117 which will serve as attachment points, to adapt to a power unit. Many different types of power units can be used in conjunction with the preset invention. - The
bottom end 118 is adapted to support a variety ofpoints 130. The type of point to be installed may be dependent upon the soil conditions of a particular job. - A component of the present invention is the manner in which the components are assembled to form flow paths for fluid to exit the blade at controlled locations and with a controlled flow rate. The flow paths of this first embodiment illustrated in
FIG. 1 are defined when thefront edge 120 is attached to theblade 110.FIG. 8 illustrates a void 124 insurface 122 of leadingedge section 120.Fluid tube 140 is adapted to travel invoid 124 to transfer pressurized fluid from the top ofplow 100 into thevoid 124, and may be sealed withweld 152 illustrated inFIG. 6 . Other forms of sealing the connection between thetube 140 and thefront edge sections 120 are possible, but are not illustrated herein as they are not a critical element of the present invention.Tube 140 has atop end 144 and abottom end 146 and may extend intovoid 124 for any desired distance, as will be explained later. - As illustrated in
FIGS. 6 and 7 the leading edge sections are attached toblade 110 with stitch welds 150. Flow paths are defined by providing asmall gap 154 between thefront surface 112 of the blade and therear surface 122. The spaces between the stitch welds 150 results a flow path for the pressurized fluid, allowing fluid to pass from thevoid 124, through thegap 154 betweensurfaces blade 110. The gap 154 (FIG. 7 ) between thesurfaces blade 110 at a certain fluid pressure. -
FIG. 15 shows an alternate arrangement of theFIG. 7 structure, having the void or groove 224 formed in the front of the blade instead of having the void or groove 124 formed in the back of the leading edge section as shown inFIG. 7 . - The fluid pressure at a certain point along the blade's length will vary. If the
tube 140 terminates at the top ofblade 110, the fluid pressure will be highest at that point and will decrease at points closer to the bottom. This is not ideal as there tends to be more resistance from the soils near the bottom of the blade, which requires the highest fluid pressure near that area. This is due to the types of soils typically encountered at lower depths. The surface soils typically include some percentage of organic matter, and higher percentage of air pockets: it is typically less dense. The soils encountered at points deeper can include the more difficult soils including clay. Thus there is an area, illustrated inFIG. 5 , as a critical high friction area. This is the area in which the fluid is most critical. In order to assure that the fluid is ejected most aggressively in thisarea tube 140 can be extended so that it terminates at a position towards the bottom of this critical high friction area, thetube end 146 is located near thebottom end 118 of theblade 110. The fluid pressure invoid 124 will be highest at the point the tube terminates. In this manner the volume of fluid at this point can be maximized. - In addition to varying the length of
tube 140, the number ofleading edge sections 120 that are welded ontoblade 110 can be varied to match the requirements of a specific job, including specific installation depths. The number of and location of the stitch welds can also be adjusted to tailor aplow 100 for a specific application. In this manner it is possible to provide a nearly infinite variety of configurations in an economic manner. - Another embodiment is illustrated in
FIGS. 9 and 10 . In this configuration a manifold 160 is installed in between theblade 110 and theleading edge sections 120. The manifold includes drilledholes 166 extending from afront side 164 to arear side 162, as illustrated inFIG. 10 . The drilledholes 166 intersect at the middle, and when theleading edges 120 are installed onto thefront side 164 the drilledholes 166 will terminate at the void 124 in theleading edge 120. In this manner a flow path is defined by thevoid 124 and theholes 166 which will allow fluid to be routed fromtube 140 tonozzles 168 that are installed at therear side 162 of themanifold 160. - In this embodiment varying the
nozzles 168 utilized in the assembly allows control of the flow rates and location of the fluid injection. Thenozzles 168 can be replaced by plugs (not shown) if there are areas where fluid is not required, and the size of thenozzles 168 can be varied if the there are areas where extra flow is required. It provides a plow that can be modified using hand tools, without welding. - Still another preferred embodiment is illustrated in
FIGS. 11 , 11A, 12 and 13. In this embodiment thefluid tube 140 has been located on the opposite side ofblade 110, therear side 114. As can be seen inFIG. 12 the fluid tube is located between theblade 110 and thechute 40. In this configuration it is protected byplates 42. The fluid tube includes an inlet fitting 142 at the top and travels to thebottom end 118 ofblade 110 where it terminates attube end 146. The cross hatched portion shown inFIG. 11A represents a weld. -
Tube end 146 is adapted to attach to abottom end section 126, as illustrated inFIG. 13 .Bottom end section 126 includes void 128 in thetop side 127 as illustrated inFIG. 14 .Tube 140 includes a bend that allows it to enter into void. Thetube 140 is then sealed by welding it to thebottom end section 126 and theblade 110 withweld 156 such that the fluid is forced intovoid 128. Thebottom end section 126 is also welded to theblade 110 at the locations where it contacts theblade 110, thus sealing thevoid 128. -
Void 128 intersects void 124 at the bottom-front corner ofblade 110. At this point the fluid is transferred to void 124 and will flow along thefront edge 112 ofblade 110. As described for the previous two embodiments, the fluid can then be allowed to travel to the edge of the blade and out to the soil either through a gap and spaces between stitch welds 150, or through a manifold 160 between thefront edge sections 120 and theblade 110.FIGS. 11 and 12 illustrate the use of the stitch welds 150 andgaps 151 between stitch welds 150. However, the manifold 160 would work equally well. - All the previously described embodiments provide a plow that can be tailored to provide fluid injection characteristics to match specific job requirements. The components are all manufactured with traditional manufacturing processes. The flow paths are defined by stacking together leading edge sections with flow voids, and welding or otherwise attaching them to a blade. This configuration provides appropriate function and provides an easily tailored configuration.
- Obviously many modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
