Embodiment Construction

[0021] Referring first to Figures 1-3, the present invention provides a uniquely structured excavating tip and joint assembly 10, which exemplarily includes a replaceable tip 12, an intermediate joint 14, and a main joint 16 to illustrate A first connector structure shown in the form of a schematically depicted connecting pin 18 and a second connector structure shown in the form of a schematically depicted connecting pin 20 . The assembly 10 is elongated in the fore-aft direction along the longitudinal axis 22 and is anchored on the leading edge portion of the bottom bucket lip 24 and protrudes forwardly beyond it, shown in FIGS. 1 and 2 . A small part of it is shown in the dotted line. Assembly 10 is one of a series of parallel spaced apart assemblies (others not shown) also attached to lip 24 and projecting forwardly therefrom.

[0022] Referring now to FIGS. 1-4 and 7 , the intermediate sub 14 has a rear base portion 26 and a front nose portion 28 . Base portion 26 has a ...

Abstract

An elongated excavation tooth assembly (12,14,16)includes a replaceable toot h point (12)and an adapter structure comprising (1) an intermediate adapter (14)having a front end nose (48)complementarily received in a rear end pocke t (72)of the point and captively retained therein by a first connector pin structure (18), and (2) a main adapter (16)having a front end nose (98)complementary received in a rear end pocket (34)of the intermediate adapter (14)and captively retained therein by a second connector pin structure(20) and a rear end operatively securable to an excavating bucket l ip (24). Special configurations of the point (12)and adapter portions (14,16)of the assembly, including horizontally elongated oval configurations of the noses (48,98), horizontal orientation of the connector pins (18,20), nose stabilization protrusions (34,114) at the nose retainer openings (66,84,116,46), and complementarily scalloped adapter and point interface areas, provide the assembly with reduced size and improved strength, wear an d operational characteristics.

Description

technical field [0001] The present invention relates generally to excavating equipment, and more particularly in a preferred embodiment thereof provides an excavating tip and joint assembly of unique construction, such as comprising a connection with a joint member having an interconnected main portion and an intermediate portion. the tip of the tooth. Background technique [0002] Large buckets, dippers, etc. are typically provided with a series of earthcutter tooth assemblies, each tooth comprising a relatively large joint member and a relatively small replaceable tooth tip. The joint part has a base portion connectable to the front lower lip of the bucket and a tapered nose to which the tips of the teeth are detachably fixed, and the tapered joint nose is received on the tooth by a suitable connecting pin or other connecting structure. In the pointed inner pocket part. The service life of the tips is rather short compared to the service life of the joint parts, which ty...
