Description
- The present disclosure relates generally to a machine work tool. Specifically, the present disclosure relates to an adjustable blade rake tool for a machine.
- Machines, such as track-type tractors, wheel dozers, track-type loaders, skid steer loaders, multi-terrain loaders, compact track loaders, track loaders, wheel loaders, wheel-tractor scrapers, as well as other machines, are often used in materials handling, construction, and other industries. These machines may include a blade, such as a dozing-type blade, for moving the materials such as soil, rock, sand, garbage, brush, and any other movable material.
- From time to time it becomes desirable to use the machine to perform raking operations to the material. Traditionally, in this situation an operator removes the blade from the machine and installs a rake tool in place of the blade. This is a difficult process and requires a lot of time to change the blade and rake each time the user wants to perform the other operation. Other solutions include mounting a rake to a front side of the blade such that the rake tines are below the lower surface of the blade. This type of rake system is in the way and must be removed if the user of the machine wants to use the blade for dozing without the rake. Still other solutions included pivotably pinning a rake to the front side of the blade such that the rake can be pivoted down so that the tines are below the lower surface of the blade when raking is desired and then the rake can be pivoted up so that the blade can be used for dozing. However, this type of system obstructs the operator's view to see over the blade when the rake is pivoted up and extends above the upper surface of the blade.
- Another solution is provided in U.S. Pat. No. 4,364,191 to Cazes (the '191 patent). The '191 patent discloses a piling rake having a blade connectible to a tractor. The rake includes a plurality of teeth extending from the bottom of the blade. The teeth are pivotably connected to permit rearward pivotal movement of the teeth away from objects encountered when the tractor moves. Fluid piston and cylinder combinations interconnect the teeth with the blade so movement of the teeth displaces pressurized fluid within the piston and cylinder combinations. The pressurized fluid reverses the pivotal movement of the teeth when the teeth clear the objects. However, this system does not allow the user to adjust a raking depth of the rake tines and must be removed from the blade when the user wants to use the blade without the rake.
- In view of the above, it is desirable to provide a more versatile integral adjustable blade rake. Thus, the present disclosure is directed to overcoming one or more of the problems discussed above.
- In one aspect, the present disclosure provides an adjustable blade rake. According to an embodiment, the adjustable blade rake includes a mounting plate configured to mount to a machine. A backup plate is coupled to the mounting plate and includes a plurality of slots. A moldboard is attached to the backup plate. A plurality of tines are slidably located in the plurality of slots adjacent to the rear side of the moldboard. A crossbar couples the plurality of tines together and a tine locking device is operatively coupled to the plurality of tines and is configured to hold the plurality of tines at a desired height in the plurality slots.
- Another aspect of the present disclosure provides a hydraulic rake system. According to an embodiment, the hydraulic rake system includes a mounting plate configured to mount to a machine. A backup plate having a plurality of slots is coupled to the mounting plate. A moldboard is attached to the backup plate. A plurality of tines are slidably located in the plurality of slots adjacent to a rear side of the moldboard. A crossbar couples the plurality of tines together. A height adjusting system is operatively coupled to the plurality of tines and configured to selectively allow the plurality of tines to slide in the plurality slots between a retracted position and an extended position as the moldboard is raised and lowered by the machine.
- In yet another aspect the present disclosure provides a machine. According to an embodiment, the machine includes a frame, an engine supported by the frame, and a propulsion system coupled to the frame and the engine. The propulsion system is configured to propel the machine. An adjustable blade rake is coupled to the frame. The adjustable blade rake includes a mounting plate. A backup plate having a plurality of slots is coupled to the mounting plate. A moldboard is attached to the backup plate. A plurality of tines is slidably located in the plurality of slots adjacent to a rear side of the moldboard. A crossbar couples the plurality of tines together. A tine locking device is operatively coupled to the plurality of tines. The tine locking device is configured to hold the plurality of tines at a desired height in the plurality slots.
- Other features, aspects, and advantages of this disclosure will be apparent from the following description and the accompanying drawings.
- The drawings illustrate exemplary embodiments of the disclosure and when accompanied with the description provided herein serve to explain the present disclosure by way of example and should not be construed to limit the present disclosure.

The blade rake assembly includes an adjustable depth feature that allows use of the blade, the rake, or the blade and rake in combination, without the need to remove the blade to add a rake and also without the need to assemble and disassemble a traditional pivoting rake to the blade.
- For example, in one embodiment, a machine operator can operate the blade, the rake, or the blade and the rake in combination by extending and retracting hydraulic cylinders configured to raise and lower the rake tines, which are embedded with structural backup plates behind the blade moldboard. The operator can control the depth of the rake infinitely within the range of rake travel using the hydraulic cylinder. In an alternative embodiment, a manual version is configured such that the rake tine depth adjustment is made at specific intervals by pinning the tines at selected heights.
- Accordingly, the adjustable blade rake of the present disclosure provides a compact rake design, which does not require removal from the blade to use the blade, and does not interfere with the operators view above and in front of the blade as do traditional rakes. The rake may be used for moving brush, raking soil, and other materials with the tines fully extended. Additionally, the rake may be used with the tines slightly extended as an aid in ripping soil and/or sod when dozing hard earth. Furthermore, the blade may be used without the rake tines when the tines are fully retracted.

FIGS. 2A , 2B, and 2C illustrate various isometric views of an embodiment of theadjustable blade rake 12 having the rake tines fully retracted. Theadjustable blade rake 12 includes a mountingplate 36 that is configured to mount tomachine 10. The mountingplate 36 is formed of a rigid material, such as steel, iron, or other material, and includes structural supports, brackets, fittings, bushings, bearings, and/or a variety of other features that allow the mountingplate 36 to mount tomachine 10. The mountingplate 36 may be configured to mount directly or indirectly to lift arm(s) 18,hydraulic cylinder 20, and/orcoupler 22. However, the shape and form of the mountingplate 36 may vary with various different machines to which theadjustable blade rake 12 is to mount. The mountingplate 36 is structurally sufficient to handle the compression, stress and/or other forces expected to be applied to the mountingplate 36 whenmachine 10 movesadjustable blade rake 12 through a material. - An
upper backup plate 38 and alower backup plate 40 are attached to the mountingplate 36. Thebackup plates moldboard 42. Thebackup plates backup plates machine 10 movesadjustable blade rake 12 through a material. Thebackup plates plate 36 via welding, fastening, riveting, or by other fixed or removable connecting means. In alternative embodiments, theadjustable blade rake 12 may include any number of backup plates and the shape and form of thebackup plates -
Upper backup plate 38 includes a plurality ofslots 39 formed through thebackup plate 38. Similarly,lower backup plate 40 includes a plurality ofslots 41 formed through thebackup plate 40. Theslots 39 in theupper backup plate 38 and theslots 41 in thelower backup plate 40 are generally aligned with one another. - The
moldboard 42 is configured to engage, dig, or otherwise receive material, such as soil, rock, gravel, and/or other materials (not shown) to be moved bymachine 10. Themoldboard 42 is formed of a rigid material, such as steel, iron, or other material and has afront side 43 and arear side 44. Therear side 44 is attached fixedly or removably to thebackup plates front side 43 receives and moves material when lowered to a position to engage the material and whenmachine 10 is traveling generally in a forward direction. To efficiently move the material,moldboard 42 is generally formed having an arcuate profile shape, such as that shown in the side view ofFIG. 2C . Such arc or radius shape allows themoldboard 42 to engage, push, and roll the material as the material moves up themoldboard 42 and tumbles forward whilemachine 10 moves in the forward direction. However, it is contemplated that the profile shape of themoldboard 42 may be other shapes. - To increase the longevity or the usable life of the
moldboard 42, one or more ground engaging tool(s) 45 formed of an alloy of metallic ground engaging materials are attached to the ground engaging or lower edge of themoldboard 42. The ground engaging tool(s) may be replaceable and may be attached to themoldboard 42 via bolting, riveting, welding, or other suitable attaching means. As should be understood by those having ordinary skill in the art, ground-engaging materials generally have a hardness and an abrasive wear resistance, which are harder and more durable than materials used in forming non-wear portions of theadjustable blade rake 12. Themoldboard 42 may be formed with or without the ground engaging tool(s) 45. - The
adjustable blade rake 12 includes a number ofrake tines 46 integrated into the structural supports of theadjustable blade rake 12. Thetines 46 are formed of a rigid material, such as steel, iron, or other material. Thetines 46 are slidably located inslots backup plates rear side 44 of themoldboard 42. In an embodiment, thetines 46 are generally formed with a front side having an arcuate profile shape substantially similar to that of therear side 44 of themoldboard 42. Accordingly, thetines 46 nest or otherwise fit compactly with themoldboard 42. It is contemplated that the profile shape of thetines 46 may be other shapes. - Similar to the
moldboard 42, thetines 46 may includeground engaging tools 47 formed of a ground engaging material attached to the ground engaging or lower edge of thetines 46. Theground engaging tools 47 may be fixedly attached via welding or may be removably attached via fasteners to thetines 46. In an alternative embodiment, thetine 46 may be entirely formed of a ground engaging material. - The
tines 46 each have atine crossbar aperture 48 formed through thetine 46. Theaperture 48 is formed to receivecrossbar 50 through the aperture of each of thetines 46 and thus, tie all of the tines together. As such, thetines 46 all slide or otherwise move substantially together in therespective slots rear side 44 of themoldboard 42. Thecrossbar 50 is formed of a rigid material, such as steel, iron, or other material. In an alternative embodiment, thecrossbar 50 is attached to thetines 46 via a means, other than through an aperture, such as welding or fastening (not shown). - Accordingly, the
tines 46 are adjustable and can all be raised together to a fully refracted position, as shown inFIGS. 2A , 2B, and 2C, lowered to a partially extended position, as shown inFIGS. 3A , 3B, and 3C, or lowered to a fully extended position, as shown inFIGS. 4A , 4B, and 4C. A lifting device 52 (e.g., a hydraulic cylinder) is coupled betweencross bar 50 andlobes 53 that are attached tobackup plate 38. As should be readily understood, thelifting devices 52, when configured as hydraulic cylinders, receive a pressurized fluid from a hydraulic system (not shown) powered by thepower system 14 to extend and retract an extendable bar. - To facilitate sliding the
tines 46 in theslots lifting devices 52 extends and retracts. When thelifting devices 52 are retracted thecrossbar 50 is pulled up toward theupper backup plate 38 and retracts thetines 46. When liftingdevices 52 are extended thecross bar 50 is pushed down toward thelower backup plate 40 and extends thetines 46. Using thelifting devices 52 thetines 46 can be adjusted to any length between the fully retracted position and the fully extended position. As can be seen inFIGS. 2B , 3B, and 4B, when the tines are moved from a fully retracted position (e.g.,FIG. 2B ) to a fully extended position (e.g.,FIG. 4B ), the liftingdevice 52 moves from a more horizontal position to a more vertical position with respect to the orientation shown in these figures. - Because the
tines 46 and theslots moldboard 42, the tines tend to travel in an arcuate path when extended. Accordingly joints 54 and/or 55 may be formed as ball joints to allow multi-dimensional motion between the liftingdevices 52, thelobes 53 and thecrossbar 50 as thetines 46 are extended and retracted. - The
adjustable blade rake 12 also includesside plates 56 attached to opposite sides of themoldboard 42. Theside plates 56 are formed of a rigid material, such as steel, iron, or other material. In an embodiment, theside plates 56 may be formed of a ground engaging material. Similar to theground engaging tools side plate 56 may be fixedly or removably attached to the adjustable blade rake 12 (e.g.,upper backup plate 38,lower backup plate 40, and/or moldboard 42) via welding, brazing, riveting, bolting, or any other suitable means. In use, theside plates 56 provide structural strength to theadjustable blade rake 12. In another embodiment, theside plates 56 may extend forward of thefront side 43 of themoldboard 42 and may assist in cutting sides of material to be moved bymachine 10. -
FIG. 5 illustrates an exploded view of an embodiment of theadjustable blade rake 12 having therake tines 46 removed. Removing thelifting devices 52 from thecrossbar 50 atjoints 55 allows the cross bar to be removed from thetine crossbar apertures 48 of eachtine 46. With thecrossbar 50 removed, thetines 46 can be lifted upward and out ofslots slots crossbar 50 slid back throughtine crossbar apertures 48. Thelifting devices 52 are then re-attached to the crossbar. As should be understood, pins, bolts, rivets, keeper rings, and/or other devices (not shown) may be used to keep thecrossbar 50 in place through thetine crossbar apertures 48, tying thetines 46 together. -
FIGS. 6 and 7 illustrate various isometric partial views of an embodiment of theadjustable blade rake 12 having manually adjustable rake tines. This embodiment may be used in addition to or as an alternative to embodiments using thelifting devices 52 to adjust extension and retraction of thetines 46. In this manual adjustment style, the side plate(s) 56 include aside plate aperture 57 through theside plate 56. Theside plate aperture 57 aligns with a number oftine adjustment apertures 58 formed through one or both of the end tines located proximate theside plates 56. When thetines 46 are adjusted to a desired extension length atine adjustment aperture 58 aligns with theside plate aperture 57. When theseapertures pin 59 is inserted through theapertures apertures tines 46 at the desired extension length. Any desirable means for keeping thepin 59 in place may be used with thepin 59. - In operation, an operator may remove
pin 59 to allow thetines 46 to raise or lower in theslots adjustable blade rake 12 usinglift arms 18 to position thetines 46 at the desired extension length. After the tines are at the desired extension length and theapertures pin 59 through theapertures tines 46 at the desired extension length. - The present disclosure relates generally to a machine work tool. Specifically, the present disclosure relates to an adjustable blade rake system configured to couple to a machine. The blade rake assembly includes an adjustable depth feature that allows use of the blade, the rake, or the blade and rake in combination, without the need to remove the blade to add a rake and also without the need to assemble and disassemble a traditional pivoting rake to the blade.
- For example, in one embodiment, a machine operator can operate the blade, the rake, or the blade and the rake in combination by extending and retracting hydraulic cylinder lifting device configured to raise and lower the rake tines, which are embedded with structural backup plates behind the blade moldboard. The operator can control the depth of the rake infinitely within the range of rake travel using the hydraulic cylinder. In an alternative embodiment, a manual version is configured such that the rake tine depth adjustment is made at specific intervals by pinning the tines at selected heights.
- Accordingly, the adjustable blade rake of the present disclosure provides a compact rake design, which does not require removal from the blade to use the blade, and does not interfere with the operators view above and in front of the blade as do traditional rakes. Furthermore, the rake may be used similar to a traditional rake (e.g., moving brush and material with the tines fully extended), or the rake may be used with the tines slightly extended as an aid in ripping soil and/or sod when dozing hard earth. Furthermore, the blade may be used without the rake when the tines are fully retracted.
- It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed adjustable blade rake. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the disclosed adjustable blade rake. It is intended that the specification and examples be considered as exemplary only, with a true scope being indicated by the following claims and their equivalents.
