Benefits of technology

The present invention provides an improved attachment for an earth-working bucket that allows for secure attachment of a straight scraping edge to the bucket. The attachment includes a pair of working plates and a pair of side plates that are joined together to form a straight scraping edge. The attachment can be positioned against the inner or outer surface of the bucket sidewalls for securement. The attachment can be easily converted from a toothed digging edge to a straight scraping edge by simply adding the attachment and positioning the side plates against the bucket sidewalls. The technical effects of the invention include improved efficiency and durability of the attachment, as well as ease of conversion between toothed and straight scraping edges.

Problems solved by technology

On smaller or emergency jobs requiring use of a backhoe, a separate grader or end loader may not be available.
As those in the construction business appreciate, a typical backhoe bucket is quite unsatisfactory for use in scraping dirt or in leveling or grading because of the teeth on the working edge of the bucket.
If the bucket is lowered enough to scrape most of the dirt from the ground to be cleared, the teeth penetrate into and tear and damage the ground, thus again requiring manual leveling and finishing.
For a variety of reasons, however, none of these prior proposals have proven satisfactory.

Embodiment Construction

[0027]FIGS. 1-12 illustrate an earth-working bucket 10 having a toothed digging edge 12 and an improved attachment 20 with a straight scraping edge 22. FIGS. 1, 2 and 12 show bucket 10 having a plurality of teeth 13 extending forwardly from edge 12 of a middle wall 14 bordered by a pair of sidewalls 15. FIG. 12 shows an example of an earth-working machine 100 which has a front bucket 10A and a rear bucket 10b of different sizes. The attachment according to the present invention may be made for buckets of different sizes.

[0028]Attachment 20 has an inner working plate 31 and an outer working plate 33 and a pair of side plates 40 each joined with both working plates 31 and 33. Working plates 31 and 33 converge together to form straight scraping edge 22. Inner working plate 31 extends generally along planes of a bucket inner middle surface 141 which during digging typically receives loosened dirt. Outer plate 33 extends generally along planes of a bucket outer middle surface 142 which d...

Abstract

An attachment for an earth-working bucket having a pair of sidewalls and a digging edge with a plurality of forwardly extending teeth. The attachment has a pair of working plates and a pair of side plates each joined with both working plates and extending rearwardly therefrom. The pair of working plates converge together to a straight scraping edge and have inside surfaces together defining a teeth-receiving cavity. A method includes placing the attachment with the straight scraping edge forward of the teeth such that the teeth are in the teeth-receiving cavity, positioning each side plate against a surface of the respective sidewall of the bucket and securing each side plate to the respective sidewall of the bucket.

Description

FIELD OF THE INVENTION[0001]This invention relates to an attachment for toothed buckets of the type used on earth working equipment. More particularly, this invention relates to a method by which a toothed digging edge is quickly converted to a straight scraping edge of such bucket.BACKGROUND OF THE INVENTION[0002]In the usual building or construction project, considerable trenching and digging normally are required as a part of such work as pouring concrete footings and foundations, laying water lines, installing drainage tile and sewer pipes and systems, uncovering existing utility pipes and lines, waterproofing and reinforcing existing foundations, and the like. Much of this trenching and digging is accomplished by the use of an earth working machine designed primarily for that type of work, such as a backhoe or similar machine equipped with a hydraulically operated boom provided at its distal end with a bucket capable of digging into and picking up and removing dirt, rocks, rubb...
