Embodiment Construction

[0034] The present invention relates to components and systems for ground engaging tools, and in particular to enable wear members such as cutting heads for use in various types of mining, earth working and construction machinery. figure 1 An embodiment of a machine 50 in the form of a track-type tractor is shown that may include wear members constructed in accordance with the principles of the invention, particularly an embodiment of an implement end cutting head. Among other uses, crawler tractors are used to move and strip work material in various surface mining or other construction applications.

[0035] Such as figure 1As shown, machine 50 may include a body 52 having a cab 54 to accommodate a machine operator. Machine 50 may also include an arm system 56 pivotally connected at one end to body 52 or underframe and supporting implement assembly 60 at an opposite distal end. In embodiments, implement assembly 60 may include any suitable implement, such as an earthworking...

Abstract

A wear member (100) for an earth working implement includes a main body ( 101). A cutting edge (140) is defined along at least a portion of the bottom interface (120). The wear member (100) includes a corrugated upper front surface (114) extending along a top edge (138) of a top interface (118) between said front portion (102) and said top portion (106). ); along the lateral edge (144) of the lateral interface (122) between said front portion (102) and said lateral portion (112); the ridge (164) on the front portion (102) , and along the spearhead edge (142) of the bottom interface (120). The wear member (100) includes a wave-shaped lower front surface (116) formed on the front portion (102) of the main body (101) adjacent to the wave-shaped upper front surface (114) located along the front portion (102) ) and the medial interface (124) between the medial portion (110) disposed between the medial edge (146), the cutting edge (140) and the ridge (164).

Description

technical field [0001] The present invention relates generally to ground engaging tools and, more particularly, to ground engaging tools on buckets, blades and other work tools for mining and construction machinery. Background technique [0002] Different types of mining and construction machinery, such as tractors, bulldozers, backhoes, excavators, motor graders, and mining trucks, commonly use soil working blades to move and level ground that is being dug or loaded or Material. Earthworking blades are frequently subject to extreme wear due to repeated contact with highly abrasive materials during operation. Replacement of earthworking blades and other implements used in mining and construction machinery can be expensive and labor intensive. [0003] Earthworking blades can be equipped with ground engaging tools (GET), such as a cutting head or set of cutting edges, to help protect the blade and other earthworking blades from wear. Typically, the cutting head may be in t...
