Description

Technical Field

[0001] This disclosure relates to work implement assemblies such as bucket assemblies used by earthmoving, mining, and construction equipment. More specifically, this disclosure relates to such assemblies using a notched base edge, a tool adapter that mates with the base edge, and an adapter cover that protects at least a portion of the tool adapter. Background Technology

[0002] Machines such as wheel loaders and excavators employ work implement assemblies, including bucket assemblies, rakes, shears, etc., with teeth or tips attached to them to aid in working on materials such as soil, rock, and sand. For example, teeth or tips can be attached to the bucket assembly to help the bucket assembly penetrate the ground, thereby facilitating the scooping of soil into the bucket. Adapters are typically attached to the working edges (e.g., base edges, side edges, etc.) of the bucket or other work implement, allowing different types of teeth or tips to be attached to the work implement. Furthermore, the tips or teeth can be easily replaced when worn by providing adapters attached to the work implement.

[0003] Many of these adapters are mechanically attached to the working edge of the work tool. However, current adapters do not always meet customer requirements for lifespan or durability.

[0004] U.S. Patent Application Publications Nos. 20200157780, 2020015779, 20200015778, 2020015777, 2020015776, and 20200157765, assigned to the applicant of this application, describe corner adapters, center adapters, corner adapter covers, center adapter covers, and base edges with notches, which are suitable for certain applications, such as buckets for the earthmoving, mining, and construction industries.

[0005] However, for other applications, continued improvements are necessary, including providing more robust corner adapters and their attachment to the base edge of the bucket or other working implements. Furthermore, adapter covers that are less expensive to manufacture are desirable. Summary of the Invention

[0006] An adapter cover according to an embodiment of the present disclosure may include a housing body including an outer surface and an inner surface, and defining a vertical direction, a horizontal direction, a lateral direction, and a vertical plane. A front portion may define a through-hole configured to allow a nose portion of the adapter to pass horizontally through the through-hole, through the inner surface, and then through the outer surface. A single top leg may extend horizontally from the front portion and may define an adapter key receiving recess on the inner surface and a top leg side portion defining a recessed arched portion extending rearward from the front portion and a convex arched portion extending horizontally from the recessed arched portion and terminating on a vertical rear surface.

[0007] An adapter cover according to an embodiment of the present disclosure may include a housing body including an outer surface and an inner surface, and defining a vertical, horizontal, lateral, and vertical plane. A front portion may define a through-hole configured to allow a nose portion of the adapter to pass horizontally through the through-hole, through the inner surface, and then through the outer surface, and a top single leg may extend horizontally from the front portion. The through-hole defines a periphery having a right edge, a left edge, a top edge, a top right corner, and a top left corner, and the through-hole also defines a bottom open end.

[0045] Reference will now be made in detail to embodiments of this disclosure, examples of which are illustrated in the accompanying drawings. Throughout the drawings, the same reference numerals will be used wherever possible to denote the same or similar parts. In some cases, the reference numerals will be indicated in this specification, and the drawings will show reference numerals followed by a letter (e.g., 100a, 100b) or by an apostrophe (e.g., 100', 100”, etc.). It should be understood that the use of a letter or apostrophe immediately following the reference numerals is to indicate that these features are similar in shape and have similar functions, as is often the case when the geometry is mirrored about a plane of symmetry. For ease of explanation in this specification, letters or apostrophes are often not included herein but may be shown in the drawings to indicate that they are copies of features discussed in this written specification.

[0046] Various embodiments of the work implement assemblies according to this disclosure will now be discussed, the work implement assemblies using a center adapter, corner adapters, a load-sharing block, a center adapter cover, corner adapter covers, and a base edge with a notch.

[0047] from Figure 1 Initially, the work implement assembly 100 may take the form of a bucket assembly 100', which includes a housing 101 defining an opening 102 communicating with a normally enclosed interior. From... Figure 1 Starting at the rear of the bucket assembly 100 shown, the bucket assembly 100 includes a curved housing profile 104, which is attached to the rear wall 106 at the top of the housing 104. The other end of the housing is attached to the bottom plate 108 of the assembly 100. A top plate 110 is attached to the top of the rear wall 106. The top plate 110 transitions to an overflow preventer 112, which is designed to allow material to leak into the interior of the bucket and prevent material from overflowing from the bucket. Reinforcing ribs 118 are provided and attached to the top plate 110 and the overflow preventer 112 to provide reinforcement. Two generally flat end plates 114 are attached to the side edges of the overflow preventer 112, the top plate 110, the rear wall 106, the bottom plate 108, and the housing 104.

[0048] Side edge assemblies 115 are attached to each end plate 114, while front edge assemblies 116 are attached to the front edge of the bottom plate 108 of the bucket assembly 100. The front edge assembly 116 includes: a base edge 700; a plurality of center adapters 200 attached to the base edge 700; a plurality of tools 118, each of which is attached to one of the plurality of center adapters 200; and a plurality of center adapter covers 900', a single center adapter cover of which is located between one of the plurality of center adapters 200 and one of the plurality of tools 118. Furthermore, two corner adapters 1100 are also attached to the base edge 700 and the side edge 120 of the bucket assembly 100'. A single corner adapter cover 1000, 1000' is located between each of the corner adapter 1100 and the tool 118. A plurality of base edge protectors 122 are also provided, each of which is located between the center adapters 200 and between the center adapters 200 and the corner adapters 1100. Side edge protectors 124 are also provided, which are attached to the side edges 120 adjacent to the corner adapters 1100 and the corner adapter covers 1000'.

[0049] It should be understood that the working implement assembly can take other forms besides the bucket assembly, including rake assemblies, shear assemblies, etc. Furthermore, any embodiment of the adapter, center adapter, corner adapter, adapter cover, corner adapter cover, center adapter cover, load-sharing block, and base edge, which will be described in more detail below, can be used to include... Figure 1 Any suitable work equipment components of those described in the text.

[0050] Now for reference Figures 2 to 12 The center adapter 200 will now be discussed in more detail. The center adapter can be used with mounting mechanism 126 (see...). Figure 11 Attach tool 118 to work tool assembly 100 (see...) Figure 10 The center adapter 200 includes a body 202, which may include a nose portion 204 configured to facilitate attachment of the tool 118. The body 202 may also include: a first leg 206 including a first leg side surface 208; a second leg 210 including a second leg side surface 212; and a throat portion 214 connecting the legs 206, 210 and the nose portion 204 together. At least one of the first leg 206 and the second leg 210 defines a hole 215 configured to receive a mounting mechanism 126 (see...). Figure 11 ).

[0051] like Figure 2 , 6As best seen in 7, 10, and 12, body 202 may define a recess 216, which defines an adjacent surface 218. Recess 216 may be located on a first leg-side surface 208 or a second leg-side surface 212, and recess 216 may define a recess height H216 and a recess width W216 (see...). Figure 2 ) and pit depth D216 (see Figure 11 ).

[0052] See Figure 2 , 6 7 and 10, the first leg 206 and the second leg 208, along with the throat portion 214, define a slot 220, which includes a closed end 222 and an open end 224. The slot 220 may be defined to an assembly direction 226 on the work implement assembly 100a. The first leg 206 may include an inclined portion 228 disposed adjacent to the closed end 222 along the assembly direction 226. The inclined portion 228 may form a first tilt angle 230 with the assembly direction 226, thereby partially defining the slot 220 (see [link to documentation]). Figure 5 The inclined portion 228 defines an inclined portion surface normal 231 that faces downward along the assembly direction 226. The first inclination angle 230 can range from 20 degrees to 40 degrees. Therefore, the slot 220 can be configured to accommodate a chamfered or beveled base edge. In other embodiments, other configurations of the slot are possible, including those forming different angles or those configured to accommodate a square base edge, etc.

[0053] See Figure 7 The recess 216 can be configured to have an opening 232 facing the assembly direction 226. The recess 216 may include a bottom recess surface 234 facing a direction 235 that is not parallel to (e.g., substantially perpendicular to) the assembly direction 226. Thus, a cantilevered wall shelf 236 is provided to protect the load-sharing block 400 from abrasion as material passes through the center adapter 200. Other configurations are possible in other embodiments.

[0054] exist Figure 7 , 11 As can be seen in Figures 1 and 12, the adjacent surface 218 is configured to mate with the load-sharing block 400 and can take the form of an arcuate surface 246. (See reference 12 for more details.) Figure 11The arcuate surface 246 may include an elliptical surface 248, which defines a secondary axis 250 ranging from 60 mm to 100 mm and a primary axis 252 ranging from 100 mm to 130 mm. The primary axis may be aligned with the assembly direction. In some embodiments, the arcuate surface 246 is divided into a plurality of surfaces with different configurations. For example, the arcuate surface 246 may also include a radial surface 254, which defines a radius of curvature 256 ranging from 50 mm to 200 mm. The radial surface 246 may be disposed between the first leg side surface 208 and the elliptical surface 248. When the center adapter 200 is pushed toward the base edge 700, a wedging effect may occur at the contact portion with the load-sharing block 400 (by...). Figure 11 (The dashed lines in the text indicate this). In other embodiments, other configurations are possible.

[0055] Now for reference Figure 2 , 3 6, 7, and 10, the slot 220 may also define a lateral direction 238 perpendicular to the assembly direction 226. The throat portion 214 may further include a first throat side surface 240 disposed along the lateral direction 230 and a second throat side surface 242 disposed along the lateral direction 238 on opposite sides of the throat portion 214. The throat portion 214 may also include a protrusion 244 disposed at the closed end 222 of the slot 220. The protrusion 244 may extend adjacent to the first throat side surface 240 and adjacent to the second throat side surface 242 along the assembly direction 226 and along the lateral direction 238.

[0056] Key Focus Figure 3 The protrusion 244 may define a protrusion height H244 along the assembly direction 226, and may also include a flat intermediate portion 258 laterally straddling the first arched portion 260 and the second arched portion 262. The flat intermediate portion 258 may define a lateral width W258. The protrusion height H244 may range from 0.1 times the lateral width W258 to 0.5 times the lateral width W258. The protrusion 244 may be complementaryly configured as a corresponding central notch 702 of the base edge 700 (e.g., designed as line-to-line). Other configurations are possible.

[0057] The first arcuate portion 260 may define a midpoint 264 and a midpoint tangent 266, the midpoint tangent forming a first obtuse angle 268 with the flat intermediate portion 258 ranging from 100 to 160 degrees (e.g., approximately 130 degrees). The first arcuate portion 260 may also define an endpoint 270 and an endpoint tangent 272, the endpoint tangent forming a second obtuse angle 274 with the midpoint tangent 266 ranging from 100 to 160 degrees (e.g., approximately 130 degrees). Other configurations are also possible. Inclined portions and protrusions may be configured to help maximize the contact area with the base edge, thereby helping to provide stability to the adapter.

[0058] Now, an adapter 300 according to another embodiment of the present disclosure will be described, which may employ a central adapter (such as...) Figures 2 to 12 (As shown) or in the form of corner adapters, etc. Reference Figure 2 , 6 7 and 8, the adapter 300 may include a body 202 comprising: a nose portion 204 configured to facilitate attachment of the tool 118; a first leg 206 including a first leg side surface 208; a second leg 210 including a second leg side surface 212; and a throat portion 214 connecting the legs 206, 210 and the nose portion 204 together. At least one of the first leg 206 and the second leg 210 may define an aperture 215 configured to receive a mounting mechanism 126.

[0059] The body 202 may also define a recess 216, which defines an adjacent surface 218. The recess 216 may be located on the side surfaces 208, 212 of at least one of the first leg 206 and the second leg 210. The recess 216 may be constructed as previously described herein.

[0060] The first leg 206, the second leg 210, and the throat portion 214 may define a slot 220, which includes a closed end 222 and an open end 224. The slot 220 may define an assembly direction 226, a lateral direction 238 perpendicular to the assembly direction 226, and a vertical direction 302 perpendicular to both the assembly direction 226 and the lateral direction 238 on the work implement assembly 100a. The throat portion 214 may also include a first throat side surface 304 disposed along the lateral direction 238 and a second throat side surface 306 disposed along the lateral direction 238 on opposite sides of the throat portion 214. The first throat side surface 304 may define a first adapter cover receiving recess 308 including a first vertical surface 310. A first key 312 may extend laterally from the first vertical surface 310. The first key 312 may provide stability and support for an adapter cover inserted into an adapter.

[0061] Similarly, the second throat-side surface 306 may define a second adapter cover receiving recess 314 including a second vertical surface 316. A second key 318 may extend laterally from the second vertical surface 318.

[0062] The body 202 includes a top surface 320 that extends from the nose portion 204 over the throat portion 214 to the first leg portion 206. The throat portion 214 may also include a first sidewall 322 that extends from the first throat side surface 304, thereby partially defining the first adapter cover receiving recess 308. A first key 312 may be spaced apart from the first sidewall 322 and also from the top surface 320.

[0063] See Figure 6 The first sidewall 322 may include a front guide portion 324 disposed adjacent to the nose portion 204 along the assembly direction 226. The front guide portion 324 may form an acute guide angle 326 ranging from 15 degrees to 30 degrees with the assembly direction 226. Furthermore, the first sidewall 322 also includes a rear abutment portion 328 disposed along the assembly direction 226 and a transition portion 330 connecting the rear abutment portion 328 to the front guide portion 324. The rear abutment portion 328 includes a rear abutment vertical surface 332. The transition portion 330 may include a serpentine shape. Other configurations of these various features are possible in other embodiments.

[0064] The first key 312 may include a first key top surface 334 and a first key bottom surface 336. The first key top surface 334 and the first key bottom surface 336 may taper along the assembly direction 226 and are configured to facilitate the attachment of an adapter cover (e.g., a center adapter cover 900) to the adapter 200.

[0065] Next, we will refer to Figures 1 to 5 The work implement assembly 100 is described. The work implement assembly 100a may include a notched base edge 700a defining a central notch 702 and a central adapter 200 configured to attach to the notched base edge 700a. The central adapter 200 has a body 202 including a nose portion 204 configured to facilitate attachment of a tool 118 using a mounting mechanism 126a (e.g., sold by the assignee of this application under the trademark CAPSURE). The mounting mechanism 126a can be used to attach the tool 118 to a lug 276 located on the nose portion 204.

[0066] The main body 202 may also have: a first leg 206 including a first leg side surface; a second leg 210 including a second leg side surface 212; and a throat portion 214 connecting the legs 206, 210 and the nose portion 204 together. At least one of the first leg 206 and the second leg 210 defines a hole 215, said hole being configured to receive the mounting mechanism 126.

[0067] The first leg 206, the second leg 210, and the throat portion 214 define a slot 220, which includes a closed end 222 and an open end 224. The slot 220 may also be defined to an assembly direction 226 and a lateral direction 238 perpendicular to the assembly direction 226 on the work implement assembly 100a. The throat portion 214 also includes a first throat side surface 240 disposed along the lateral direction 238 and a second throat side surface 242 disposed along the lateral direction 238 on opposite sides of the throat portion 214. The throat portion 214 also includes a protrusion 244 disposed at the closed end 222 of the slot 220. The protrusion 244 may extend adjacent to the first throat side surface 240 and adjacent to the second throat side surface 242 along the assembly direction 226 and along the lateral direction 238.

[0068] Key Focus Figure 3 The protrusion 244 may define a protrusion height H244 along the assembly direction 226. The protrusion 244 may have a flat intermediate portion 258 laterally straddled by a first arched portion 260 and a second arched portion 262. The flat intermediate portion 258 may also define a lateral width W258. The protrusion height H244 may range from 0.1 times the lateral width W258 to 0.5 times the lateral width W258.

[0069] The first arcuate portion 260 defines a midpoint 264 and a midpoint tangent 266, the midpoint tangent forming a first obtuse angle 268 with the flat middle portion 258 ranging from 100 to 160 degrees (e.g., approximately 130 degrees). Similarly, the first arcuate portion 260 may also define an endpoint 270 and an endpoint tangent 272, the endpoint tangent forming a second obtuse angle 274 with the midpoint tangent 266 ranging from 100 to 160 degrees (e.g., approximately 130 degrees). A central notch 702 of the notched base edge 700a is complementary to the protrusion 244, thereby contacting the protrusion 244 (e.g., designed line-to-line).

[0070] See Figure 4 and 5The notched base edge 700a may include a front portion 704, which includes a top beveled surface 706. The first leg 206 includes an inclined portion 228 disposed adjacent to the closed end 222 along the assembly direction 226. The inclined portion 228 may form a first tilt angle 230 with the assembly direction 226, thereby partially defining the slot 220. The first tilt angle 230 may range from 20 degrees to 40 degrees. The inclined portion 228 may contact the top beveled surface 706. The engagement between the adapter and the base edge can provide a maximum contact area to reduce adapter stress during loading and unloading, and the bow-shaped portion can reduce stress in the base edge. The components may be “pre-installed” or designed line-to-line, which can help provide adapter support during loading by aiding in load distribution.

[0071] like Figure 11 and 12 As shown, the work implement assembly 100a may also have a load-sharing block 400 attached to a notched base edge 700a having an arcuate reinforcing surface 402. The work implement assembly 100a may also have a vertical mounting mechanism 126' disposed in a hole 215 in at least one of the first leg 206 and the second leg 210.

[0072] The body 202 of the center adapter 200 defines a recess 216 disposed on a first leg-side surface 208, the recess defining an abutment surface 218 that is complementary to the arcuate reinforcing surface 202, thereby contacting the arcuate reinforcing surface 402 (e.g., designed line-to-line). A load-sharing block 400 may be laterally spaced from the first leg-side surface 208 by a predetermined lateral distance 128.

[0073] Now refer to Figures 13 to 15 Various embodiments of the load-sharing block 400 mentioned above and their associated features are discussed in more detail herein. The load-sharing block 400 may include a body 404 comprising a flat outer surface 406 defining a first end 408 and a second end 410. A first arcuate outer portion 412 extends from the first end 408 of the flat outer surface 406, and a second arcuate outer portion 414 extends from the second end 410 of the flat outer surface 406. The first arcuate outer portion 412 terminates at a first free end 416 and includes a first elliptical outer surface 418 extending from the first free end 416.

[0074] In addition, such as Figure 15As best viewed from the center, the first arcuate outer portion 412 may further include a first radial surface 420 disposed between the first elliptical outer surface 418 and the flat outer surface 406. The first elliptical outer surface 418 may define a secondary axis 422 ranging from 30 mm to 60 mm and a principal axis 424 ranging from 70 mm to 100 mm. The first radial surface 420 may define a radius of curvature 426 ranging from 50 mm to 100 mm.

[0075] The main body 404 may also include a flat inner surface 428 offset inwardly by a predetermined thickness 430 from the flat outer surface 406. In a similar manner, the first arcuate inner portion 432 may be offset inwardly by the same predetermined thickness 430 from the first arcuate outer portion 412.

[0076] The main body 404 can also be defined in a vertical direction 434 perpendicular to the predetermined thickness 430 (see also...). Figure 13 ) and height 436 measured along the vertical direction 434. The height 436 can range from 1.5 times the predetermined thickness 430 to 3.0 times the predetermined thickness 430.

[0077] Furthermore, the body 404 may define a midpoint 438 of the flat outer surface 406 and a plane of symmetry 440 passing through the midpoint 438. The body 404 may also include a top surface 442 disposed along a vertical direction 434, the top surface forming a right angle 444 with the flat outer surface 406 and the first elliptical outer surface 418. The body 404 may also include a bottom surface 446 and a chamfered surface 448 extending from the bottom surface 446 to the first arched inner portion 432 and the flat inner surface 428. The chamfered surface 448 may form a chamfered obtuse angle 450 with the bottom surface 446 at a first free end 416, ranging from 30 degrees to 60 degrees.

[0078] The beveled feature allows solder balls to be used to attach the load-sharing block to the base edge, while the symmetry of the load-sharing block allows it to be used on opposite sides of the adapter. In other embodiments of this disclosure, the construction of these various features of the load-sharing block may be changed or omitted.

[0079] We will continue to refer to this. Figures 13 to 15 Another embodiment of the load sharing block 400 is discussed. Such a load sharing block 400 may include a body 404, the body including: a flat outer surface 406 defining a first end 408 and a second end 410; a first arcuate outer portion 412 extending from the first end 408 of the flat outer surface 406; and a second arcuate outer portion 414 extending from the second end 410 of the flat outer surface 406.

[0080] Key Focus Figure 15The flat inner surface 428 can be offset inward by a predetermined thickness 430 from the flat outer surface 406. The first arcuate inner portion 432 can be offset inward by the same predetermined thickness 430 from the first arcuate outer portion 412. Moreover, the second arcuate inner portion 432' can be offset inward by the same predetermined thickness 430 from the second arcuate outer portion 414.

[0081] The first arcuate outer portion 412 may terminate at the first free end 416 and may include a first elliptical outer surface 418 extending from the first free end 416 toward the flat outer surface 406. The second arcuate outer portion 414 may also terminate at the second free end 416' and may include a second elliptical outer surface 418' extending from the second free end 416' toward the flat outer surface 406.

[0082] The first arcuate outer portion 412 may further include a first radial surface 420 disposed between the first elliptical outer surface 418 and the flat outer surface 406. The second arcuate outer portion 414 may further include a second radial surface 420' disposed between the second elliptical outer surface 418' and the flat outer surface 406.

[0083] The second elliptical outer surface 418' can be constructed symmetrically with the first elliptical outer surface 418, and both the first elliptical outer surface 418 and the second elliptical outer surface 418' can define a secondary axis 422 ranging from 30 mm to 60 mm and a principal axis 424 ranging from 70 mm to 100 mm. The second radial surface 420' can be constructed symmetrically with the first radial surface 420, and both the first radial surface 420 and the second radial surface 420' can define a radius of curvature 426 ranging from 50 mm to 100 mm.

[0084] The main body 404 may also be defined by a vertical direction 434 perpendicular to the predetermined thickness 430 and a height 436 measured along the vertical direction 434. The height 436 may range from 1.5 times the predetermined thickness 430 to 3.0 times the predetermined thickness 430.

[0085] The main body 404 may include a top surface 442 disposed along a vertical direction 434, the top surface forming a right angle 444 with the flat outer surface 406 and the first elliptical outer surface 418. The main body 404 may also include a bottom surface 446 and a chamfered surface 448, the chamfered surface extending from the bottom surface 446 to the first arcuate inner portion 432 and the flat inner surface 428.

[0086] Return to reference Figure 2 , 6According to embodiments of the present disclosure, the work implement assembly 100 utilizing the load-sharing block 400 and the center adapter 200 can be characterized as follows. The work implement assembly 100b may include a base edge 700 and a center adapter 200 configured to attach to the base edge 700. The center adapter 200 may include a body 202 having: a nose portion 204 configured to facilitate attachment of a tool 118; a first leg 206 including a pair of first leg opposing side surfaces 208'; a second leg 210 including a pair of second leg opposing side surfaces 210'; and a throat portion 214 connecting the legs 206, 210 and the nose portion 204.

[0087] At least one of the first leg 206 and the second leg 210 may define a hole 215 configured to receive a mounting mechanism 126. A body 202 may define a first top recess 216a that defines a first top recess arcuate abutment surface 218a adjacent to one of a pair of opposing side surfaces 208' of the first legs. The first leg 206, the second leg 208, and the throat portion 214 may define a slot 220 including a closed end 222 and an open end 224. The slot 220 defines an assembly direction 226, a lateral direction 238 perpendicular to the assembly direction 226, and a vertical direction 302 perpendicular to both the lateral direction 238 and the assembly direction 226 on the work implement assembly 100. The work implement assembly 100b may also include a first load-sharing block 400a that includes a first arcuate reinforcing surface 402a engaging the first top recess arcuate abutment surface 218a.

[0088] In a similar manner, the body 202 also includes a second top recess 216b, which defines a second top recess arcuate abutment surface 218b adjacent to another of a pair of first leg opposing side surfaces 208'. The work implement assembly 100b may also have a second load-sharing block 400b, which also includes a second arcuate reinforcing surface 402b that engages the second top recess arcuate abutment surface 218b.

[0089] refer to Figure 11 The first load-sharing block 400a and the second load-sharing block 400b are configured to create a wedge profile 278 for pulling into the center adapter 200, thereby providing support for lateral and vertical loads. Furthermore, the first load-sharing block 400a may be laterally spaced from one of a pair of opposing side surfaces 208 of the first legs, and the second load-sharing block 400b may be laterally spaced from the other of a pair of opposing side surfaces 208' of the first legs.

[0090] The work implement assembly 100 may further include a vertical mounting mechanism 126' disposed in a hole 215 in at least one of the first leg 206 and the second leg 210. The first arcuate reinforcing surface 402 may include an elliptical surface 418a and a radial surface 420.

[0091] The elliptical surface 418a may define a secondary axis 422 ranging from 30 mm to 60 mm and a principal axis 424 ranging from 70 mm to 100 mm. The radial surface 420 may define a radius of curvature 426 ranging from 50 mm to 100 mm.

[0092] The aforementioned geometry and features of the load-sharing block 400 serve the following functions: An elliptical load-sharing block profile maximizes the contact area and reduces the risk of rapid material growth in the load-sharing block, which could cause interference between the load-sharing block and the adapter, making installation or removal of the load-sharing block more difficult. In some embodiments, an arcuate load-sharing block profile may match the profile of the adapter. The gap between the load-sharing block and the adapter helps limit interference when the load-sharing block is installed or removed from the adapter. Any of these functions may be omitted or may be present in various embodiments of this disclosure.

[0093] Next, we will refer to Figures 16 to 20 and Figures 32 to 34 A corner adapter 500 according to various embodiments of the present disclosure is discussed. The corner adapter 500 may be configured to allow attachment of a tool 118 to a work implement assembly 100 using a mounting mechanism 126. See also... Figure 16 The corner adapter 500 may include a body 502 defining a vertical direction 504 and a horizontal direction 506. The body 502 may include a nose portion 508 configured to facilitate attachment of the tool 118 (e.g., via a lug 510 for use with a mounting mechanism 126a, such as the mounting mechanism sold under the trademark CAPSURE by the assignee of this invention, see...). Figure 32 and 33 ).

[0094] The focus now is on Figures 16 to 18The body 502 may also have a first forked leg 512, the first forked leg including a pair of first leg side surfaces 514. The first forked leg 512 may define a vertical slot 516 dividing the first forked leg 512 into a first forked portion 518 and a second forked portion 520. The body 502 may also have: a second leg 522 including a pair of second leg side surfaces 524; and a throat portion 526 connecting the legs 512, 522 and the nose portion 508 together. At least one of the first forked portion 518 and the second forked portion 520 defines a hole 528, the hole being configured to receive a mounting mechanism 126 (e.g., the mounting mechanism 126 may take the form of a horizontal mounting mechanism 126, see below). Figure 18 , 29 and 30).

[0095] Continue to refer to Figure 16 A first leg 512, a second leg 522, and a throat portion 526 define a horizontal slot 530, which includes a closed end 532 and an open end 534. The horizontal slot 530 may define an assembly direction 536 on the work implement assembly 100. The first forked leg 512 may include a first inclined portion 538 disposed in a vertical slot 516. The first inclined portion 538 may form a first acute angle 540 with the assembly direction 536 ranging from 20 degrees to 40 degrees (e.g., approximately 30 degrees). Figure 19 The first inclined portion 538 may define a first inclined portion surface normal 550 pointing upward toward the assembly direction 536. In other words, in some embodiments of this disclosure, the first acute angle 540 faces the assembly direction 536.

[0096] like Figure 17 As shown, the horizontal slot 530 defines a lateral direction 542 perpendicular to the assembly direction 536. The throat portion 526 also includes a first throat side surface 544 disposed along the lateral direction 542 (see...). Figure 18 ) and a second throat side surface 546 disposed on the opposite side of the throat portion 526 along the lateral direction 542. The throat portion 526 also includes a protrusion 548 disposed at the closed end 532 of the horizontal slot 530 (see Figure 16The protrusion 548 extends adjacent to the first throat side surface 544 and the second throat side surface 546 along the assembly direction 536 and along the lateral direction 542. The first forked leg portion 512 may define a key receiving slot 547 disposed in front of the hole 528 along a horizontal direction 506. The key receiving slot 547 is disposed on at least one of the pair of first leg side surfaces 514 and defines an open end 549 facing the nose portion 508 (e.g., in the direction opposite to the assembly direction 536) along the horizontal direction 506. In some embodiments of this disclosure, the key receiving slot 547 may also be disposed at least partially above the horizontal slot 530 vertically.

[0097] Furthermore, the horizontal slot 530 defines a vertical height 531 with a gap, and the protrusion 548 includes a flat intermediate portion 554, which is laterally straddled by a first arched portion 556 and a second arched portion 558 (see also...). Figure 20 The flat middle portion 554 can also define the width 560 of the lateral middle portion and the vertical height 561 of the lateral middle portion (see...). Figure 16 In some embodiments of this disclosure, the lateral intermediate vertical height 561 ranges from 0.7 to 0.75 times the gapped vertical height 531. In some embodiments of this disclosure, the horizontal slot 530 may define a top gap portion 533, and in a plane encompassing both the horizontal and vertical directions (e.g., Figure 16 The minimum thickness 535 of the throat portion 526, measured between the top gap portion 533 and the outer throat surface 537 in the plane of the view in the middle, ranges from 1.6 to 1.9 times the vertical height 531 with the gap.

[0098] exist Figure 20 In the middle section, the first arcuate portion 556 may define a midpoint 562 and a midpoint tangent 564, the midpoint tangent forming a first obtuse angle 566 with the flat middle portion 554 ranging from 100 degrees to 160 degrees (e.g., approximately 130 degrees). Similarly, the first arcuate portion 556 may also define an endpoint 568 and an endpoint tangent 570, the endpoint tangent forming a second obtuse angle 572 with the midpoint tangent 564 ranging from 100 degrees to 160 degrees (e.g., approximately 130 degrees). Thus, Figure 20 The structure shown is different Figure 3 The structure. In other embodiments of this disclosure besides those explicitly shown and described herein, Figure 3 and 20 Other constructions of its features are possible.

[0099] return Figure 16At least one of the first fork portion 518 and the second fork portion 520 may include a lifting band 521 extending vertically upward from either or both of these fork portions. As mentioned earlier herein, one of a pair of first leg side surfaces 514 may define a first key receiving slot 547 defining an open end 549 disposed adjacent to the nose portion 508 and extending along the assembly direction 536 and terminating at a rear abutment surface 578. Furthermore, a top expansion wall 580 and a bottom expansion wall 582 are provided to partially define the first key receiving slot 547. The top expansion wall 580 and the bottom expansion wall 582 are configured to facilitate attachment of the corner adapter cover 1000 (see [link to documentation]). Figures 32 to 34 ).

[0100] like Figure 18 As is best viewed in the present disclosure, body 502 may define a vertical plane of symmetry 586. This may not be the case for other embodiments of the present disclosure.

[0101] Now, refer to Figures 16 to 20 An adapter 500 according to yet another embodiment of this disclosure is discussed. It should be noted that the adapter 500 may take the form of a center adapter or a corner adapter.

[0102] refer to Figure 16 The adapter 500 can be configured as previously described herein to have the following features. The first and second legs (e.g., 512, 522) and the throat portion 526 may include an upper surface 602 and a lower surface 604 that at least partially define a slot (e.g., 530), the slot including a closed end 532 and an open end 534. The slot may be defined to an assembly direction 536 on the work implement, a lateral direction 542 perpendicular to the assembly direction 536, and a vertical direction 504 perpendicular to the assembly direction 536 and the lateral direction 542. The slot may define a protrusion 548 at the closed end 532 of the slot, the protrusion including a flat intermediate portion 554 laterally straddled by the first arched portion 556 and the second arched portion 558. The flat intermediate portion 554 may define a lateral intermediate portion width 560 (see...). Figure 20 ), and the protrusion distance 606 measured along the assembly direction from the closed end 532 of the slot to the flat middle portion 554, and the range of the protrusion distance 606 can be from 0.8 to 1.2 times the lateral middle portion width 560.

[0103] In addition, the main body 502 defines the arc-shaped boundary surface 626 (see Figure 16The arcuate boundary surface extends from the closed end 532 to at least one of the upper surface 602 and the lower surface 604. The upper surface 602 may be a horizontal surface 628 and the lower surface 604 may be a horizontal surface 630. In other embodiments, this may not be the case.

[0104] like Figure 16 As shown, the slot may define a bottom void portion 636 adjacent to the closed end. This portion 636 may define a vertical height 538 of the bottom void portion, measured from the lower surface 604 to the lower end of the bottom void portion 636. In some embodiments of this disclosure, the vertical height 638 of the bottom void portion may range from 0.1 to 0.15 times the vertical height 561 of the intermediate portion.

[0105] Refer again Figure 18 , 19 and Figures 32 to 34 The work implement assembly 100 according to embodiments of the present disclosure will now be described. Figure 19 As best viewed from the center, the work tool assembly 100 may include a base edge 700 and a corner adapter 500 attached to the base edge 700 and contacting the base edge 700. The corner adapter 500 may include a body 502 defining a vertical direction 504, a horizontal direction 506, and a vertical plane 586 passing through the body 502 (see [link to documentation]). Figure 18 The main body 502 may have a nose portion 508, which is configured to facilitate attachment of the tool 118.

[0106] Now, refer to Figures 21 to 25 The base edge 700 according to various embodiments of the present disclosure is discussed. The base edge 700 may have a body 708 including a working edge 710 defining a lateral direction 712 and an assembly direction 714 perpendicular to the lateral direction 712 (so named because this is the direction in which an adapter or tool is attached to the base edge). The body 708 may also define a first lateral end 716, a second lateral end 718, a plurality of vertical mounting mechanism receiving holes 720, a plurality of central recesses 702 extending from the working edge 710 (so named because the central recesses are spaced apart from the lateral ends), and a first end recess 724 disposed adjacent to the first lateral end 716 and a second end recess 724' disposed adjacent to the second lateral end 718. The first end recess 724 and the second end recess 724' may also extend from the working edge 710.

[0107] Each of the plurality of central recesses 702 and the first end recesses and second end recesses 724, 724' may include different configurations. For example, the first end recess 724 and the second end recess 724' may define a recess depth 725 along the assembly direction 714 (see [link to assembly direction]). Figure 25The depth of the notch is greater than the corresponding dimension of the central notch 702. That is, the depth of the end notch 725 can be greater than the depth of the central notch 725' (see...). Figure 24 Each of the plurality of central notches 702 and the first end notches and the second end notches 724, 724' may further include a straight intermediate portion 726, said straight intermediate portion being laterally straddled by the first arched corner portion 728 and the second arched corner portion 728' (see...).

[0108] The first arc-shaped angle portion 728 may define an arc midpoint 732 and an arc midpoint tangent 734, the arc midpoint tangent forming a first angle 736 with the straight middle portion 726 ranging from 100 degrees to 160 degrees (e.g., approximately 130 degrees). The first arc-shaped angle portion 728 may also define an arc endpoint 738 and an arc endpoint tangent 740, the arc endpoint tangent forming a second angle 742 with the arc midpoint tangent 734 ranging from 100 degrees to 160 degrees (e.g., approximately 130 degrees).

[0109] See Figure 21 and 24 The body may also include a chamfered surface 706" extending from the working edge 710, the chamfered surface at least partially defining each of a plurality of central recesses 722 and each of a first end recess 724 and a second end recess 724'.

[0110] Additionally, the working edge 710 can be divided into multiple regions 744, which are arranged along the lateral direction 712 and offset from each other along the assembly direction 714. The multiple regions 744 may include a central region 744a, which includes three of a plurality of linearly laterally aligned central notches 722.

[0111] Multiple regions 744 may also include a first end region 744b, the first end region including a first end notch 724, the first end notch being spaced from the first lateral end by a first end distance 746 ranging from 20mm to 60mm (see...). Figure 25The plurality of regions 744 also includes: a first intermediate region 744c, which is laterally disposed between the central region 744a and the first end region 744b; and a second intermediate region 744d, which is laterally disposed between the first intermediate region 744c and the first end region 744b. The first intermediate region 744c may be offset by a first offset distance 748 along the assembly direction 714, and the second intermediate region 744d may be offset by a second offset distance 750 from the central region 744a. The first end region 744b may be offset by a third offset distance 752 from the central region 744a. The third offset distance 752 may be greater than the second offset distance 750, and the second offset distance 750 may be greater than the first offset distance 748. Other configurations are possible in other embodiments of this disclosure.

[0112] Furthermore, the plurality of regions 744 includes a plurality of angled regions 744e. One of the plurality of angled regions 744e may be located between the central region 744a and the first intermediate region 744c. Another of the plurality of angled regions 744e may be located between the first intermediate region 744c and the second intermediate region 744d. A third of the plurality of angled regions 744e may be located between the second intermediate region 744d and the first end region 744b. The central region 744a may define a central region midpoint 754, and the body 708 may define a plane of symmetry 756 passing through the central region midpoint 754 (see...). Figure 24 This may not be the case in other embodiments.

This may not be the case for other embodiments of this disclosure. Furthermore, the central region 744a may include three of a plurality of central notches 702 that are laterally linearly aligned with each other, while other regions may have only one central notch 702. This may not be the case for other embodiments of this disclosure.

Furthermore, the lift belt 948 may be horizontally positioned in front of the tool adapter lift belt receiving notch 946, which extends vertically upward from the single top leg 918.

Other configurations are possible in other embodiments of this disclosure.

Figures 26 to 28 (shown in the figure); first leg 206, which includes a pair of first leg opposite side surfaces 208'; second leg 210, which includes a pair of second leg opposite side surfaces 210'; and throat portion 214, which connects the legs 206, 210 and nose portion 204 together.

[0127] Continue to refer to Figure 6 and 7 At least one of the first leg portion 206 and the second leg portion 210 defines a hole 215, said hole being configured to receive a mounting mechanism 126. The body 202 may define a first top recess 216a, the first top recess defining an arcuate abutment surface 218a adjacent to one of the pair of opposing side surfaces 208' of the first leg portions. Furthermore, the first leg portion 206, the second leg portion 210, and the throat portion 214 define a slot 220, said slot including a closed end 222 and an open end 224. The slot 220 may define an assembly direction 226 on the work implement assembly 100e. The body 202 may define a top center adapter cover receiving recess 308'.

[0128] The focus now is on Figures 26 to 28 The work implement assembly 100 may further include a center adapter cover 900', which includes a housing body 902 having an outer surface 904 and an inner surface 906. The housing body 902 may also define a vertical direction 908, a horizontal direction 910, and a vertical plane 912 (which may be a plane of symmetry 912'). The housing body may also have a front portion 914 defining a through-hole 916 configured to allow a nose portion 204 of the center adapter 200 to pass horizontally through the through-hole 916, through the inner surface 906, and then through the outer surface 904. Furthermore, a top leg 918 may extend horizontally from the front portion 914, and a bottom leg 932 may also extend horizontally from the front portion 914.

[0129] A center adapter cover 900' can be clamped between tool 118 and center adapter 200. The top leg 918 of the center adapter cover 900' can rest at least partially in the top center adapter cover receiving recess 308' of the center adapter 200. The center adapter 200 may include a top surface 320, and the top leg 918 of the center adapter cover 900' can rise vertically above the center adapter 200, while the bottom leg 932 of the center adapter cover 900' can extend vertically below the center adapter 200. This helps protect the adapter when material passes over and under the cover (see...). Figure 23 Material flow path 136 in the text.

[0130] For this purpose, tool 118 may define a tool top surface 132, and the center adapter cover 900' may define a cover top surface 966 that merges with the tool top surface 132. Tool 118 may also define a tool bottom surface. In other embodiments, other configurations of these various features are possible.

[0131] Other features will now be described that allow material to flow along material flow path 136, etc., over the adapter and cover. For example, the front portion 914 may include a front radial surface 970 between the tool top surface 132 and the cover top surface 966. Thus, these features can be configured to provide a material flow path 136 along the tool top surface 132 over the cover top surface 966. Furthermore, the front portion 914 of the center adapter cover 900' defines a front portion perimeter 976, and the front radial surface 970 may extend entirely along the front portion perimeter 976 (see...). Figure 31 ).

[0132] Other features that allow material flow to be reversed may be provided. For example, the top leg 918 of the center adapter cover 900' defines a top rear chamfer 972 that is angled from the top surface 966 of the cover toward the first leg 206 of the center adapter 200.

[0133] Return to reference Figures 29 to 31 and Figures 35 to 37 Another embodiment of the adapter cover can be seen, which can take the form of a center adapter cover or a corner adapter cover. (Focus on...) Figures 35 to 37 The adapter cover 1000 may include a housing body 1002, which includes an outer surface 1004 and an inner surface 1006. The housing body 1002 may also define a vertical direction 1008, a horizontal direction 1010, and a vertical plane 1012 (which may be a symmetrical plane 1012' but is not required; see [link]). Figure 37The housing body 1002 may also include a front portion 1014 defining a through-hole 1016 configured to allow a nose portion 508 of the adapter 500 to pass horizontally through the through-hole 1016, through the inner surface 1006, and then through the outer surface 1004. A single top leg 1018 may be provided to extend horizontally from the front portion 1014 and define an adapter cover key 1020 on the inner surface 1006. Furthermore, a side portion 1022 of the top leg may be provided (see...). Figure 35 The recessed bow-shaped portion 1024 extends rearward from the front portion 1014. The protruding bow-shaped portion 1026 can extend horizontally from the recessed bow-shaped portion 1024 and terminates at the vertical rear surface 1028.

[0134] See Figure 36 The adapter cover key 1020 can be spaced apart from the vertical rear surface 1028 and can define a vertical adapter key size 1032 ranging from 40mm to 60mm, a horizontal key height 1034 ranging from 25mm to 35mm, and a lateral key width 1030. The ratio of the horizontal key height 1034 to the vertical adapter key size 1032 can be in the range of 1.5 to 3.0. In other embodiments, other dimensions and ratios are possible. Figures 35 to 37 In the embodiment shown, the horizontal key height exceeds the vertical adapter key size, and the vertical adapter key size exceeds the side key width.

[0135] like Figure 37 As depicted, the through-hole 1016 may define a trapezoidal periphery 1038 having a right edge 1040, a left edge 1042, and a top edge 1044. In some embodiments of this disclosure, the through-hole 1016 may also define a bottom open end 1036 having a bottom open end lateral width 1036w ranging from 0.4 to 0.6 of the total width W1002 of the adapter cover.

[0136] The top leg 1018 may terminate along the horizontal direction 1010 (or plane) at the U-shaped portion 1062 (see... Figure 35 and 36 The top leg 1018 may also include a chamfer 1064 that extends horizontally from the rear U-shaped portion 1062 toward the front portion 1014.

[0137] The top single leg may take the form of a top forked leg 1122 extending horizontally from the front portion 1014. The top forked leg 1122 may include a shelf 1124 that spans horizontally along the front portion 1114 and defines a top vertical slot 1126 that divides the top forked leg 1122 into a right forked portion 1128 and a left forked portion 1130.

[0138] The top fork leg 1122 may include a V-shaped pad 1134 disposed on the top of the shelf 1124, and the right fork portion 1128 and the left fork portion 1130 may extend from the shelf 1124. Furthermore, the top fork leg 1122 may also define a cut 1162 that extends horizontally on the top of the V-shaped pad 1134 and through the V-shaped pad 1134.

[0139] Figures 32 to 34 A work implement assembly 100 according to various embodiments of the present disclosure is depicted. The work implement assembly 100 may include a base edge 700 and a corner adapter cover 1000 comprising a housing body 1002, the housing body including an outer surface 1004 and an inner surface 1006 (see...). Figures 35 to 37 ).

[0140] exist Figures 32 to 34 In the middle, the corner adapter 500 can be attached to the base edge 700. The tool 118 can be attached to the nose portion 508 as previously described herein. Figures 32 to 34 In this case, the tool assembly 100 may also include a side edge 120. A corner adapter cover 1100 may be clipped between the tool 118 and the corner adapter 500.

[0141] exist Figure 33 In the center, the corner adapter 500 may include a top surface 596, and the top forked leg portion 1122 of the corner adapter cover 1000 may rise vertically above the center adapter 500. The side edge 120 may be disposed in a top vertical slot 1126 of the corner adapter cover 1100 (see...). Figure 32 and 33 In the vertical slot 516 of the corner adapter 500 (see) Figure 17 ).

[0142] Continue to refer to Figure 33 Tool 118 may define a tool top surface 132, and corner adapter cover 1100 may define a corner adapter cover top surface 1154 that is at least partially fused with the tool top surface 132. In addition, tool 118 may define a tool bottom surface 134.

[0143] The front portion 1114 of the corner adapter cover 1100 may include a front radial surface 1158 between the tool top surface 132 and the corner adapter cover top surface 1154, which is configured to provide a flow path along the tool top surface 132 above the corner adapter cover top surface 1154.

[0144] For a similar purpose, the front portion 1014 of the corner adapter cover 1100 may define a front portion periphery 1160. The front radial surface 1158 may extend entirely along the front portion periphery 1160 (see...). Figure 37 ).

[0145] Other streamlined features can be provided. For example, such as... Figure 32 As shown, the top fork leg 1122 may further define a cutout 1162 that extends horizontally over and through the top of the V-shaped pad 1134. The work implement assembly 100f may also include a side edge protector 124 attached to the side edge 120, the side edge protector including a V-shaped front portion 1164 disposed in the cutout 1162. The V-shaped front portion 1164 may define a top apex 1166, while the V-shaped pad 1134 may define a bottom apex 1168 positioned adjacent to the top apex 1166. These features allow material to flow more easily into and along the sides of the work implement assembly 100f. In other embodiments of this disclosure, other configurations of these various features are possible, and these various features may be omitted.
