Embodiment Construction

[0042] refer to figure 1 , with the aid of technical background, a bucket, shovel or similar member 2 (hereinafter also sometimes simply referred to as "container") is conventionally attached to a piece of excavating equipment 4 . The front lip 6 is usually attached separately to the bucket in any of various ways, but could also be formed by the bucket itself if desired. The lip delimits the front edge 8 of the bucket. Excavating teeth 10 are spaced across the width of the bucket and project from the lip in the direction of forward travel of the excavating apparatus. An adapter 12 is inserted between each tooth and the bucket lip. Each adapter has a front end to which the excavating teeth are typically replaceably attached, and a rear portion 14 delimited by upper and lower legs 16, 18, respectively, which overlap the respective sides of the bucket lip. on the upper and lower surfaces 20, 22 and slides onto the lips.

[0043] Bucket teeth are subject to heavy wear and roug...

Abstract

A connection for firmly securing an adapter for detachably carrying a replaceable digging tooth at its front end to a lip of an excavating container of excavating equipment. The adapter has an upper leg and a lower leg located proximate respective upper and lower surfaces of the lip. The connection has substantially aligned openings in the legs and the lip, and engagement sections of the adapter legs traverse the opening in the lip proximate and forward of an aft end thereof. A pressure applying unit, such as a hydraulic actuator, is arranged inside the opening and generates a generally horizontally acting force which draws the adapter and the lip towards each other. A stress member, which can be a C-clamp, is operatively coupled to the hydraulic actuator and resiliently deforms relative to its relaxed shape when it is subjected to the horizontally acting force.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of granted U.S. Patent Application No. 12 / 881,997, filed September 14, 2010, which claims the benefit of U.S. Provisional Application No. 61 / 276,786, filed September 15, 2009, the entire contents of which are incorporated by reference way incorporated into this article. Background technique [0003] Equipment that moves and excavates on the ground uses tools such as shovels and buckets to dig out dirt, gravel, rock formations, etc. and remove them. Typically, such buckets have lips along their digging edges which in turn house digging teeth. [0004] Since the digging teeth and their connection to the lip of the bucket are exposed to constant abrasion, impact, etc., they experience the most severe wear and tear in the entire bucket because. Thus, they require frequent replacement. According to the prior art, the replacement of the excavating teeth is rather time-consuming, du...
