Description
- This application is a continuation-in-part of co-pending Application Ser. No. 09/207,984, filed on Dec. 8, 1998.
- This invention relates generally to an implement of a work machine, and, more particularly, to a base edge protection assembly for an implement of a work machine.
- A work machine, such as an excavator, may include a bucket for moving or excavating dirt or other types of material. A number of teeth are typically attached to a base edge of the bucket in order to facilitate the excavating process. The teeth also help protect the base edge of the bucket from wear and tear encountered during the excavation process. Protection of the base edge extends the life of the bucket and reduces maintenance cost of the work machine. However, the teeth have to be periodically replaced due to the wear and tear they are subjected to during the excavation process.
- Heretofore, some teeth have been secured to a bucket by first attaching an adapter to the base edge thereof and then securing the teeth to the adapter via a pin assembly. Typically, these pin assemblies include a number of parts which contact and exert a force on both the adapter and the tooth in order to effect the securement therebetween.
- Another approach to secure teeth to a base edge of a bucket is to utilize a tooth bar. In particular, a tooth bar is designed to fit over the base edge of a bucket and a number of adapters are secured to the tooth bar. Replaceable teeth are then secured to the adapters with pin assemblies similar to the ones described above.
- One disadvantage of having a pin assembly in contact with both the tooth and the adapter to effect securement therebetween is that the pin assembly may become loose as the tooth is subjected to substantial forces during a work operation. In particular, forces that are applied to the tooth during a work operation would then be transmitted to the pin assembly. Thereafter, forces which are applied to the pin assembly would be transmitted to the adapter. Consequently, the pin assembly would be subjected to a continuous compressing force during the work operation which may cause the pin assembly to become loose over a period of time. The presence of a loose pin assembly may cause inadvertent separation of the tooth from the adapter.
- Furthermore, these types of tooth bars and pin assemblies typically include a relatively large number of parts which makes them relatively expensive, mechanically complex, and difficult to install.
- The present invention is directed to overcoming one or more of the problems or disadvantages associated with the prior art.
- In accordance with one aspect of the present invention, there is provided a base edge protection assembly for an implement of a work machine. The base edge protection assembly includes a digging plate having (i) a first edge and a second edge, (ii) a surface interposed the first edge and the second edge, and (iii) a plurality of notches defined in the first edge of the digging plate so that a number of teeth are integrally formed on the digging plate. The base edge protection assembly also includes a cover plate secured to the surface of the digging plate at a location interposed the first edge and the second edge so that (i) a first portion of the surface extends outwardly from the location in a first direction, (ii) a second portion of the surface extends outwardly from the location in a second direction, and (iii) an edge slot is defined between the digging plate and the cover plate.
- In accordance with another aspect of the present invention, there is provided an implement assembly. The implement assembly includes a digging plate having (i) a first edge and a second edge, (ii) a surface interposed the first edge and the second edge, and (iii) a plurality of notches defined in the first edge of the digging plate so that a number of teeth are integrally formed on the digging plate. The implement assembly also includes a cover plate secured to the surface of the digging plate at a location interposed the first edge and the second edge so that (i) a first portion of the surface extends outwardly from the location in a first direction, (ii) a second portion of the surface extends outwardly from the location in a second direction, and (iii) an edge slot is defined between the digging plate and the cover plate. The implement assembly further includes a bucket having a base edge. The bucket is positioned relative to the digging plate and the cover plate so that the base edge is located within the edge slot.
- In accordance with yet another aspect of the present invention there is provided a work machine. The work machine includes a digging plate having (i) a first edge and a second edge, (ii) a surface interposed the first edge and the second edge, and (iii) a plurality of notches defined in the first edge of the digging plate so that a number of teeth are integrally formed on the digging plate. The work machine also includes a cover plate secured to the surface of the digging plate at a location interposed the first edge and the second edge so that (i) a first portion of the surface extends outwardly from the location in a first direction, (ii) a second portion of the surface extends outwardly from the location in a second direction, and (iii) an edge slot is defined between the digging plate and the cover plate. The work machine further includes an implement having a base edge. The implement is positioned relative to the digging plate and the cover plate so that the base edge is located within the edge slot.

edge protection assembly 72 also includes a number ofstraps 106. Eachstrap 106 has (i) afirst end 108 secured to coverplate 84 and (ii) asecond end 110 secured to diggingplate 74 so thatsecond end 110 is located within agap space 104. In particular, eachstrap 106 is welded to coverplate 84 and diggingplate 74 in the above described manner. - Referring now to FIG. 6, base
edge protection assembly 72 further includes a pair ofbrackets 112 and a pair of end braces 116. Both end braces 116 are substantially identical and thus only oneend brace 116 will be discussed in detail herein. As shown in FIG. 10,end brace 116 has anupper leg portion 118 and alower leg portion 120.End brace 116 is positioned relative to coverplate 84 and diggingplate 74 such thatupper leg portion 118 ofend brace 116 contacts an end edge 122 (see FIG. 6) ofcover plate 84.End brace 116 is further positioned relative to coverplate 84 and diggingplate 74 such thatlower leg portion 120 contacts anend edge 126 of diggingplate 74. Once positioned in the above described manner (i)upper leg portion 118 is welded to endedge 122 and (ii)lower leg portion 120 is welded to endedge 126. Theother end brace 116 is attached to opposite end edges ofcover plate 84 and diggingplate 74 in a substantially identical manner. Onebracket 112 is welded toupper leg portion 118 of eachend brace 116.Bracket 112 can also be welded toupper surface 96 ofcover plate 84. - As shown in FIGS. 8, 9, and10, base
edge protection assembly 72 is positioned relative tobucket 12 in a substantially identical manner as described above for baseedge protection assembly 16. In particular, baseedge protection assembly 72 is positioned relative tobucket 12 such thatbase edge 14 of wall segment 33 (see FIG. 1) is aligned withedge slot 94. Baseedge protection assembly 72 is then advanced towardbucket 12 such that (i)base edge 14 is located withinedge slot 94 and (ii)brackets 112 extend intobucket cavity 32.Brackets 112 are then bolted to wallsegments brackets 112wall segments edge protection assembly 72 tobucket 12 such thatbase edge 14 is located within inedge slot 94. Note that as shown in FIGS. 8-10,base edge 14 can have acutting edge plate 114 secured thereto in a well known manner so that whenbase edge 14 is positioned withinedge slot 94, cuttingedge plate 114 is also positioned withinedge slot 94. It should be appreciated that havingupper surface 96 andlower surface 98 ofcover plate 84 substantially flat facilitates the positioning of cuttingedge plate 114 withinedge slot 94. - Implement
assembly 10 can be utilized to excavate earth during the performance of a work function. Having baseedge protection assembly bucket 12 in the above described manner during an excavation process has several advantages as will be discussed below in reference to baseedge protection assembly 16, however, it should understood that these advantages also apply to baseedge protection assembly 72. For example, one advantage of baseedge protection assembly 16 is thatteeth 24 thereof facilitates the ability of implementassembly 10 to penetrate the ground, which in turn enhances the ability of implementassembly 10 to perform a digging function. In addition, having base edge 14 located withinedge slot 46 of baseedge protection assembly 16 protectsbase edge 14 ofbucket 12 from the wear and tear implementassembly 10 encounters during an excavation process. Protection of thebase edge 14 extends the life ofbucket 12 and reduces the maintenance cost of implementassembly 10. Moreover, it should be understood that baseedge protection assembly 16 can be easy removed frombucket 12 once baseedge protection assembly 16 wears out. Specifically,brackets wall segments edge protection assembly 16 removed frombucket 12. Once removed, a replacement baseedge protection assembly 16 can be attached tobucket 12 in a manner substantially identical as previously discussed. - An additional advantage of base
edge protection assembly 16 is that diggingplate 20 is a unitary metallic plate (e.g. steel) withteeth 24 being formed by cutting notches intoforward edge 58 of diggingplate 20. Formingteeth 24 in the above described manner results inteeth 24 being integral to diggingplate 20, and thus ensures thatteeth 24 will not inadvertently become separated frombucket 12 during the performance of a work function. This is in contrast to other base edge protection or tooth bar assemblies which utilize adapters and pin assemblies to secure the teeth. These types of tooth bar assemblies (i.e. ones that utilize adapters and pin assemblies) are more prone to having their teeth inadvertently detached due to the wear and tear the adapters and pin assemblies are subjected to during an excavation process. - Base
edge protection assembly 16 has additional advantages over other tooth bar designs that utilize adapters and pin assemblies. For example, formingteeth 24 by cuttingnotches 22 intoforward edge 58 of diggingplate 20 rather that utilizing adapters and pin assemblies for attaching the teeth results in a base edge protection assembly that (i) has relatively fewer parts, (ii) is relatively inexpensive to manufacture, (iii) is not as mechanically complex, and (iv) is relatively easy to install. - While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description is to be considered as exemplary and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected. Other aspects and features of the present invention can be obtained from a study of the drawings, the disclosure, and the appended claims.
