Abstract
The invention is a land clearing rake that is typically mounted on a moldboard on a conventional bulldozer. The land clearing rake pivots about a shaft that is horizontally connected to the front of the moldboard. The rake is comprised of teeth connected to each other by heavy-duty plates between each of the teeth. The teeth may be arranged in one or more sections wherein the sections can be simultaneously raised or lowered by winches mounted on the moldboard. The winches are remotely controlled from the operator's seat. Thus, the land clearing rake is capable of being quickly raised or lowered by the operator while the earth moving equipment is moving back to prepare for another forward move. The ability to quickly transition between raking and grading modes significantly improves the efficiency of land clearing operations.
Description
- This invention relates to attachments for earth moving equipment, such as bulldozers, front-end loaders, skidders, graders, and the like. More particularly, this invention relates to a set of raking teeth that are pivotally secured to a moldboard used on heavy equipment, such as a bulldozer or other earth moving equipment.
- Bulldozers with planar moldboards, or blades, mounted on the front are commonly used in a variety of land clearing applications including raking and grading. In raking applications, roots, limbs, and other undesirable debris are removed from an area. For grading applications, the lower edge of the moldboard is scraped along a surface in order to smooth or level the land. In order to perform the raking operation, bulldozers sometimes rely upon attachments with protruding teeth to serve as a rake. These teeth may be an integral feature of a specialized moldboard that protrude beyond the lower edge of the moldboard or the teeth may be a pivoting fixture attached to the moldboard that may be deployed or undeployed without removal.
- Bulldozer moldboards with integral teeth tend to limit the use of the bulldozer to either a raking mode or a grading mode. Typically, in order to change between modes, one moldboard is completely removed and a different moldboard installed. The time to perform this somewhat cumbersome task is usually significant and results in unwanted down time for the equipment. Separate bulldozers could be used to avoid changeover time, but this practice is often economically impractical. Another disadvantage of this approach is that the additional moldboard to be used must be moved from one work site to the next. To accommodate the additional moldboard, additional trailer space for transportation is necessitated.
- In many cases, the prior art utilizes a pivoting fixture attached to the moldboard that allows the teeth to be deployed or undeployed without removal. In some cases, the time and effort required to transition between the deployed and undeployed positions is significant. In other cases, the time and effort required to transition between the deployed and undeployed positions may be reduced, but the assembly may not always provide a method to place the teeth in a position that minimizes interference with the use of the moldboard. There is a need for an earth moving device that overcomes the shortcomings of the prior art.

FIG. 6 is a flow diagram for a method to perform a land clearing operation, according to some embodiments. - According to the embodiments described herein, a land clearing rake is disclosed. The land clearing rake includes a set of heavy-duty teeth that are specifically contoured for efficient raking of roots and other land clearing debris when the rake is in the deployed position. The rake teeth pivot about a shaft that is horizontally connected to the front of the dozer moldboard, or blade, near the midpoint of the dozer moldboard. The land clearing rake teeth are connected to each other by means of heavy-duty plates between each of the teeth.
- The disclosed land clearing rake may attain many configurations. In one embodiment, the invention involves two sections of teeth and plates. In this embodiment, the two teeth near the center of the dozer moldboard are not connected to each other by plates. The sections are hinged at the center-point on the front of the moldboard and can be simultaneously raised and lowered by means of two winches. The winches may be electric, hydraulic, or mechanical. The winches are mounted on top of each side of the dozer moldboard and are connected to the rake by cables. The winches are capable of being remotely controlled by a lever, switch, button, knob or other suitable control mechanism located at the operator's seat. When the land clearing rake is deployed, the teeth project beyond the lower edge of the moldboard. During the raking operation, the earth moving equipment moves forward with the moldboard in a lowered position so that the teeth dig into the surface to be raked.
- A
land clearing rake 100, as illustrated inFIGS. 1-5 , is installed on aconventional bulldozer 10, according to some embodiments.FIG. 1 is an isometric view of a land clearing rake mounted on a bulldozer moldboard in the deployed position, according to some embodiments.FIG. 2 is a frontal view of the land clearing rake (ofFIG. 1 ) mounted on a bulldozer moldboard in the deployed position, according to some embodiments.FIG. 3 is a two-dimensional side view of the land clearing rake (ofFIG. 1 ) mounted on a bulldozer moldboard in the deployed position (with dashed lines illustrating the undeployed position), according to some embodiments.FIG. 4 is a cutaway view of the right side (as viewed from the front of the bulldozer) of the interface between the tubular mounting sleeve assembly and shaft, according to some embodiments.FIG. 5 is a side view of a typical tooth on the land clearing rake, according to some embodiments.FIG. 6 is a flow diagram for a method to perform a land clearing operation using the land clearing rake. - As shown in
FIGS. 1-5 , theland clearing rake 100 includesteeth 12,plates 13, a tubularmounting sleeve assembly 14, ashaft 15,shouldered washers 16,lock washers 16 a,bolts 17,bushings 18, cableswivel shafts 19,brackets 20,cables 21,winches 22, andmoldboard cutouts 23, according to some embodiments.Elements - Referring specifically to
FIG. 1 , theland clearing rake 100 is attached to thebulldozer 10 that includes a verticallymovable moldboard 11 or blade. According to some embodiments, theland clearing rake 100 is constructed of two sections, each of which includesseveral teeth 12 fastened to each other byplates 13. The relative sizes and shapes ofteeth 12 andplates 13 may be modified as needed for a variety of applications, including but not limited to land clearing, snow/ice removal, sand work, gravel work, timber work, and mining. The sections of the land clearing rake are pivotally connected to themoldboard 11 by the shaft 15 (Ref.FIG. 4 ) that passes through the tubularmounting sleeve assembly 14 as well as through the holes located at the top end of the teeth 12 (Ref.FIGS. 4 and 5 ). The tubularmounting sleeve assembly 14 is fastened to themoldboard 11 at the midsection of themoldboard 11; however, in some embodiments, the tubular mounting sleeve assembly may be mounted at a position near the midsection of the moldboard 11 (i.e. within 12 inches of the centerline of the moldboard). Theshaft 15 is contained in the tubularmounting sleeve assembly 14 byshouldered washers 16,lock washers 16 a, and bolts 17 (FIG. 4 ). - Two
bushings 18 contain each of the cableswivel shafts 19.Cable brackets 20 secured to the cableswivel shafts 19 are used to attachcables 21 to each section of theland clearing rake 100. Thecables 21 are attached to thecable brackets 20 by buttons or other suitable means and are secured to the drums ofwinches 22. In some embodiments, thecables 21 may be replaced by ropes or chains. - The
winches 22 are mounted securely to a topplanar surface 23 available on themoldboard 11. Thebrackets 20 are situated near the outer regions of the cableswivel shafts 19 and thecables 21 are wound around the innermost region of the drum on each winch 22 (i.e. from the inside of the drum to the outside of the drum). This configuration helps ensure that thecables 21 feed properly onto the drums of thewinches 22. In addition, the components of theland clearing rake 100 are designed so that thebrackets 20 are as near horizontal as possible when theland clearing rake 100 is in the undeployed position. The moldboard cutouts 23 provide an unobstructed path for thecables 21 during all phases of operation. -
FIG. 2 shows theland clearing rake 100 in the undeployed position as viewed from directly in front of thebulldozer 10, according to some embodiments. From this perspective, it is apparent that theland clearing rake 100 is made up of two sections. In particular, this view shows that the twomiddle teeth 12 of theland clearing rake 100 are not connected. According to this embodiment, each section of theland clearing rake 100 is independently manipulated by thecable 21 andwinch 22. The protrusion of theteeth 12 below the lower edge of themoldboard 11 is also shown in this view. -
FIG. 3 depicts theland clearing rake 100 in the deployed and undeployed positions. The undeployed position is illustrated by the dashed lines. In the deployed position, theteeth 12 extend beyond the lower edge of themoldboard 11. In the undeployed position, theteeth 12 extend beyond the upper edge of themoldboard 11. The shoulderedwasher 16 and thebolt 17 are also visible inFIG. 3 . - The deployed position is accomplished by lowering the
teeth 12 andplates 13 against themoldboard 11 using thewinches 22 to unwind thecables 21. As thecables 21 unwind, the weight of theteeth 12 andplates 13 provides the force necessary to position the land clearingrake assembly 100 in the deployed position. Thus, theteeth 12 are held against the moldboard by gravity when theteeth 12 are not in contact with earth, rocks, and debris. In this position, thecables 21 are ideally held taught enough to keep thebrackets 20 positioned near vertical. This ensures that thecables 21 stay properly positioned on the drums of thewinches 22. When the earth moving equipment is moving forward and theteeth 12 are in contact with earth, rocks, and debris, theteeth 12 are forced against themoldboard 11 by the earth, rocks, and debris. When the earth moving equipment is moving backward, theteeth 12 are free to move away from themoldboard 11 if they are in contact with the earth, rocks, and debris. In many applications, the operator of the earth moving equipment could either raise theland clearing rake 100 while making a backward move or leave theland clearing rake 100 in the deployed position while moving backward. - The undeployed position is accomplished by using the
winches 22 to wind thecables 21 onto the drums of thewinches 22. Thecables 21 are positioned such that thecables 21 initially wrap around the inboard area of the drums on thewinches 22 and progress outwardly.Moldboard cutouts 23 provide unobstructed paths to allow the cables to move transversely as needed to wrap around the drums of thewinches 22. Thebrackets 20,cable swivel shafts 19, andbushings 18 are pulled up toward thewinches 22, as thewinches 22 wind in more of thecables 21. As a result, the lower ends of theteeth 12 are raised upward and the pivotal ends of theteeth 12 rotate with theshaft 15. As the assembly moves toward the undeployed position, thebrackets 20 are continuously aligned with thecables 21 and point directly toward thewinches 22 because thebrackets 20 and thecable swivel shafts 19 rotate freely inside thebushings 18. When the assembly is in the undeployed position, theteeth 12 are firmly pressed against the upper edge ofmoldboard 11; thebrackets 20 are directly aligned with thecables 21 that are wound on thewinches 22; and thecables 21 are taught. The result is an assembly that is firmly and securely positioned against themoldboard 11. -
FIG. 4 illustrates the interface between theshaft 15, tubular mountingsleeve assembly 14,teeth 12, shoulderedwasher 16, lockwasher 16 a, andbolt 17. This interface is typical for both ends of theshaft 15. Theshaft 15 is a continuous one-piece shaft that is drilled and threaded on both ends. The annular clearance between theshaft 15 and tubular mountingsleeve assembly 14 is great enough to allow the shaft to rotate freely in the tubular mountingsleeve assembly 14. Less annular clearance exists between the holes in theteeth 12 and theshaft 15. The different annular clearances are intended to encourage theteeth 12 to rotate with theshaft 15 so that the rotation and the corresponding frictional forces on the assembly are distributed across a greater surface area (i.e. the area between theshaft 15 and the tubular mounting sleeve assembly 14). The result is lower frictional forces on the mechanism at the interfaces between theteeth 12 and theshaft 15. This serves to reduce the wear on the mechanism at these interfaces and increases the operational life of theteeth 12 andshaft 15. - The
shaft 15 is slightly shorter than the tubular mountingsleeve assembly 14. Shoulderedwashers 16 protrude slightly inside the tubular mountingsleeve assembly 14 and rest securely against theshaft 15 without binding against the tubular mountingsleeve assembly 14. This orientation allows theshaft 15 to float transversely a small amount. Those skilled in the art may recognize other acceptable methods of containing theshaft 15. - The outermost segments of the tubular mounting
sleeve assembly 14 are significantly shorter than the inner segments. This feature allows placement of theoutermost teeth 12 near the outer edges of themoldboard 11 to maximize the land clearing rake coverage area and still provide ample structural support for theteeth 12. The lengths of the components that comprise the tubular mountingsleeve assembly 14 may vary. -
FIG. 5 is a side view oftooth 12 situated in the deployed configuration of theland clearing rake 100. In the deployed configuration, the convex-like side oftooth 12 rests against themoldboard 11. Accordingly, that portion of thetooth 12 is contoured to fit snugly against the moldboard 11 (Ref.FIG. 3 ). Therefore, this contour may vary depending upon the size and shape of the moldboard. The concave-like side of thetooth 12 is contoured to allow for efficient raking of roots and other land clearing debris. The concave-like side of thetooth 12 is also contoured to provide the structural support needed to perform the land clearing function. The hole at the upper end of thetooth 12 is present to allow theshaft 15 to pass through the tooth 12 (Ref.FIG. 4 ). Other shapes of thetooth 12 may be employed to enhance the function of theland clearing rake 100. For example,special tooth 12 shapes may be developed and utilized to allow the land clearingrake assembly 100 to move snow, ice, sand or gravel, etc. -
FIG. 6 is a process flow diagram that illustrates a method for clearing land using the land clearing rake, according to some embodiments. Most land clearing is accomplished by moving earth moving equipment forward then backing a distance to begin another forward move. The land clearing rake is advantageous because it provides a method for an operator to utilize both the forward and backward moves to perform a function, thereby increasing the efficiency of a land clearing operation. For example, it is advantageous if the forward move of the earth moving equipment is used to rake earth and debris while the backward move of the earth moving equipment is used to back drag and somewhat smooth the surface. In order to attain this efficiency, the land clearing rake is capable of being quickly raised or lowered by the operator while the earth moving equipment is moving back to prepare for another forward move. With this capability, the operator of the earth moving equipment can effectively back drag for a degree of leveling while simultaneously raising or lowering the land clearing rake, thereby significantly reducing the time lost transitioning from raking to grading mode. - It is also common for bulldozer moldboards to have guards that extend above the moldboard in order to prevent limbs, roots, and other debris being pushed from falling behind the dozer moldboard. It would be advantageous if the prior art allowed the operator to firmly and rigidly secure the teeth in an undeployed location that would allow maximum utility of the conventional moldboard and serve as a debris guard in land clearing operations. The land clearing rake performs this function when positioned in the undeployed position because the cables and winches hold the assembly firmly against the moldboard when it is undeployed. Moreover, the land clearing rake does not unduly impede the operator's vision when it is in the undeployed position.
- While the invention has been described with respect to a limited number of embodiments, those skilled in the art will appreciate numerous modifications and variations therefrom. It is intended that the appended claims cover all such modifications and variations as fall within the true spirit and scope of the invention.
