Problems solved by technology

The system is designed to allow each digging tooth to be "ground out of the hole" without compromising the bearing area of ​​the adapter; however, as the digging tooth is "ground out of the hole", debris may fill the hole, masking the appearance and possible damage to the adapter
This solution also requires the digging teeth to define large clearances in the area extending around the adapter, which also weakens the digging teeth at critical areas subject to greater loads.

Embodiment Construction

[0051] figure 1 A work machine 10 according to one embodiment of the invention is shown. As shown, work machine 10 may be a loader 11 . It is also shown that the construction machine 10 is provided with at least one work implement 15, shown in this embodiment as a bucket 16, for digging and / or moving material, such as gravel or earth.

[0052] Such as Figure 1 to Figure 2B As shown, work tool 15 is provided with at least one excavating tooth assembly, preferably a plurality of excavating tooth assemblies (eg 20 in this figure). As best shown in FIG. 2 , these excavating tooth assemblies 20 are each provided with an adapter 21 and an excavating tooth 25 . According to one aspect of the present embodiment, the adapter 21 functions as an interface that releasably secures the excavating tooth 25 to the work tool 15 .

[0053] As shown in FIG. 2 , the adapter 21 may be fixed to the front lower edge portion 17 of the work tool 15 . Those of ordinary skill in the art will appre...

Abstract

The present invention relates to an excavating tooth for construction machinery and a method for replacing an excavating tooth of construction machinery. The excavating tooth is provided with a working end and a mountable end. The mountable end defines a means for receiving an adaptor mounted on a work tool. The working end defines a bore. A wear indicator is located within the bore and provided with a length that is less than an unworn length of the working end and a color that visibly contrasts with a color of the working end. As the excavating tooth is worn down during use, the wear indicator becomes visible to provide a visual indication of the need to replace the excavating tooth.

Description

technical field [0001] The invention relates to a wear indicator system for excavating teeth on construction machinery. Background technique [0002] Construction machines (including, for example, skid steer loaders, excavators, bulldozers, and loaders) may be provided with work tools in the form of buckets or shovels. Typically, the front edge of such a bucket or digging shovel is equipped with digging teeth. To secure the digging teeth to the bucket or shovel, the digging teeth usually cooperate with adapters provided on the bucket or shovel. For example, the front lower lip on the bucket may be provided with a series of adapters and digging teeth extending along the length of the lip. [0003] During use, the digging teeth are subject to wear, which requires replacement of the digging teeth from time to time. Failure to replace digging teeth in a timely manner can result in damage to the adapters, which are usually more expensive than replacing just the digging teeth. ...
