  • a hydraulic excavator is shown, the machine could be any earthmoving machine capable of receiving attachment of a bucket assembly of the type described herein without departing from the scope of the invention.
  • the bucket 15 of the bucket assembly 14 includes a plurality of panels 22, including a bottom panel 23 and two side panels 24.
  • the bottom panel 23 extends between the two side panels 24 and includes a terminal region 25 having an edge 30.
  • Each of the tooth projections 20 may include a tooth adapter 31 and a tooth tip 32 attached to the tooth adapter 31 by a retention mechanism 33.
  • each of the tooth projections may be a unitary structure (not shown) attached to the edge 30.
  • the tooth projections 20 may include one or more of a wide variety of contours, shapes, and retention systems without departing from the scope of the invention.
  • FIGS. 3, 4 and 5 illustrate the attachment 21 on its own.
  • the attachment 21 includes a plate 34 having first and second opposing major surfaces 16, 17 (FIG. 4), first and second major edges 18, 19, and first and second minor edges 26, 27.
  • the major edges 18, 19 of the plate 34 have a width "Wl” approximately equal to a width "W2" of the edge 30 of the bottom panel 23 of the bucket 15.
  • the minor edges 26, 27 of the plate 34 have a length "L3" that, when the attachment 21 is attached to the bucket 15, extends at least from the edge 30 of the bottom panel 23 of the bucket 15 to beyond the tooth tips 32 of the tooth projections 20.
  • the plate 34 may further include a tapered or beveled region 37 at which a thickness "T" (FIG. 5) of the plate 34 is reduced to sharpen the second major edge 19 thereof. Sharpening the second major edge 19 may enhance the precision and efficiency of the attachment 21 as a grading tool.
  • the attachment 21 further includes first and second attachment adapters 35, 40 extending from the second opposing major surface 17 of the plate 34 in proximal relation to the first and second minor edges 26, 27 of the plate 34, respectively.
  • Each of the attachment adapters 35, 40 includes first and second straps 28, 29 that cooperate to define a gap 36.
  • the gap 36 is dimensioned to receive portions of the terminal region 25 and the edge 30 of the bottom panel 23 of the bucket 15.
  • Each of the straps 28, 29 of each of the adapters 35, 40 includes a surface 38 for engaging the bottom panel 23 of the bucket 15 proximal to the edge 30 thereof.
  • the dimensions of the straps 28, 29 may be varied to
  • the lengths "LI", “L2" of the first and second straps 28, 29 may be approximately equal (as shown in FIG. 3) or the length "LI" of the first strap 28 may be greater than the length "L2" of the second strap 29 (as shown in FIGS. 4 and 5).
  • the adapters 35, 40 could each include only one strap (i.e., either the first or second strap 28, 29 rather than both), or if the adapters 35, 40 do each include the first and second straps 28, 29, one of the straps 28, 29 could be formed by attaching a plate or similar structure to an adapter having only one strap.
  • the attachment 21 still further includes an attachment mechanism such as first and second brackets 41, 42 for detachably attaching the attachment 21 to the bucket 15.
  • the first and second brackets 41, 42 are "L" brackets that extend from the first and second adapters 35, 40, respectively.
  • each of the brackets 41, 42 includes a first leg 45 and a second leg 50.
  • the first leg 45 of each of the brackets 41, 42 is attached to the first strap 28 of one of the adapters 35, 40, while the second leg 50 of each of the brackets 41, 42 is oriented for detachable attachment to whichever of the side panels 24 of the bucket 15 is proximal to the adapter 35, 40 carrying the bracket 41, 42.
  • the first and second brackets 41, 42 each define a port 43 for receiving a removable fastener such as a nut and bolt 44.
  • the ports 43 are oriented such that, when the attachment 21 is being attached to the bucket 15, the ports 43 align with corresponding ports 51 defined by the side panels 24 of the bucket 15.
  • a removable fastener such as a nut and bolt 44.
  • the ports 43 are oriented such that, when the attachment 21 is being attached to the bucket 15, the ports 43 align with corresponding ports 51 defined by the side panels 24 of the bucket 15.
  • many different types of removable fasteners could be used and multiple removable fasteners could be used relative to each of the side panels 24 of the bucket 15 without departing from the scope of the invention.
  • the earthmoving machine 10 may use the tooth projections 20 of the bucket assembly 14 to cut, loosen, or dig through compacted work material. After the compacted work material is suitably loosened, the attachment 21 may be attached to the bucket 15 without first having to remove the tooth projections 20 from the bucket 15.
  • FIG. 6 illustrates the bucket assembly 14 with the attachment 21 attached as described herein.
  • the attachment 21 is attached to the bucket 15 of the bucket assembly 14 by orienting each of the attachment adapters 35, 40 between a pair of adjacent tooth adapters 31 on the tooth projections 20 and urging the attachment adapters 35, 40 onto the bottom panel 23 of the bucket 15 until associated proximal portions of the terminal region 25 and the edge 30 of the bottom panel 23 are fully and securely received in the gaps 36 defined by the attachment adapters 35, 40.
  • the fasteners 44 may then be utilized to attach the attachment mechanisms— in the illustrated embodiments, the second legs 50 of the brackets 41, 42— to the side panels 24 of the bucket 15.
  • the second major surface 17 of the plate 34 engages the tooth projections 20 and the plate 34 extends away from the bucket assembly 14 in substantially transverse relation to the edge 30 of the bottom panel 23 of the bucket 15 further than the tooth tips 32 of the tooth projections 20, thereby preventing the tooth projections 20 from disrupting the loosened work material while the attachment 21 is in use.
  • earthmoving machine 10 may urge the plate 34 of the attachment 21, in particular the major surfaces 16, 17 and the second major edge 19 of the plate 34, through the loosened work material in order to level or more evenly distribute such material in a desired manner.
  • the attachment 21 may be detached from the bucket 15 by reversing the above attachment steps, after which the tooth projections 20 may once again be used as desired.
  • the attachment 21 may alternatively be provided with more than two attachment adapters, for instance to support a larger size of the attachment 21 on a larger bucket.
  • the attachment 21 in addition to the first and second attachment adapters 35, 40, the attachment 21 includes a third attachment adapter 52 for helping to stabilize the attachment 21 on the bucket 15 and to support and distribute loading stresses sustained by the attachment 21 during use.
  • the third attachment adapter 52 is configured similarly to the first and second attachment adapters 35, 40.
  • the attachment 21 is herein described in connection with grading, the attachment 21— specifically the second major edge 19 of the plate 34 of the attachment 21— may be used as a cutting edge for cutting into work material and helping to urge cut work material into the bucket 15 of the bucket assembly 14.
