Excavating lip-mounted adapter and associated connection and shielding apparatus

a technology of adapters and lip-mounted adapters, which is applied in the field of excavating apparatus, can solve the problems of undesirably reducing the efficiency of earth penetration, undesirably weakening the adapter/lip attachment strength, and undesirably subjecting to high tensile stresses, and achieves enhanced attachment strength, reduced overall height of the adapter, and strong weld joint

Abstract

Various embodiments of an excavating bucket are provided in which a spaced series of excavating tooth adapters are secured to a front edge of a lip portion of the bucket by welding opposite side ear portions of the adapters into complementarily shaped front edge recesses in the lip to thereby substantially strengthen the adapter / lip weld joints. Each adapter is configured in a manner such that no portion thereof extends rearwardly along the bottom side of the lip, thereby desirably reducing the vertical thickness of each adapter. Front lip edge protectors may be interdigitated with the adapters and suitably secured to the lip in a variety of manners, and replaceable tooth points are removably secured to front nose portions of the adapters.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention generally relates to excavating apparatus and, in representative embodiments thereof, more particularly provides improved excavating tooth adapters and associated techniques for operatively mounting them on the forward lower lip portion of an excavating device such as an excavating bucket.

[0002] Large excavating buckets, dippers or the like are typically provided with a spaced series of earth-cutting teeth which are each formed from two primary parts—a relatively large adapter and a relatively small replaceable point. The adapter has a rear base portion which is welded to a front portion of the excavating lip, and a forwardly projecting nose portion onto which the replaceable tooth point is removably secured by a suitable connecting pin or other connecting structure. Additionally, a series of replaceable lip protectors or shields may be interdigitated with the adapters, and suitably secured to the lip, to shield front edge po...
