Abstract
An excavator bucket, which includes a mounting and a blade. The blade extends downwardly from the mounting at an angle of between 40 degrees and 50 degrees. The blade has a mounting attachment end which is attached to the mounting, a ground piercing end, and opposed upstanding outwardly angled sidewalls. The blade has a forward oriented curvature or bend spaced from the ground piercing end.
Description
- The present invention relates to an excavator bucket designed to minimize ground disturbance during use.
- When working in environmentally sensitive areas it is desirable to minimize ground disturbance. There will hereinafter be described an excavator bucket that was expressly developed for use in such environmentally sensitive areas.
- According to the present invention there is provided an excavator bucket, which comprises a mounting and a blade. The blade extends downwardly from the mounting at an angle of between 40 degrees and 50 degrees. The blade has a mounting attachment end which is attached to the mounting, a ground piercing end, and opposed upstanding outwardly angled sidewalls. The blade having a forward oriented curvature or bend spaced from the ground piercing end.
- These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to in any way limit the scope of the invention to the particular embodiment or embodiments shown, wherein:
-
FIG. 1 is a side elevation view of the excavator bucket constructed in accordance with the teachings of the present invention. -
FIG. 2 is a front elevation view of the excavator bucket ofFIG. 1 . -
FIG. 3 is a top plan view of the excavator bucket ofFIG. 1 . -
FIG. 4 is a side elevation view of an alternative embodiment of the excavator bucket ofFIG. 1 . - The preferred embodiment, an excavator bucket generally identified by
reference numeral 10, will now be described with reference toFIG. 1 through 3 . - Structure and Relationship of Parts:
- Referring to
FIG. 1 ,excavator bucket 10 includes amounting 12 includingmounting plate 13 and ablade 14.Blade 14 extends downwardly from mounting 12 at an angle of 45 degrees, but preferably between 40 degrees and 50 degrees. Referring toFIG. 3 ,blade 14 has amounting attachment end 16, aground piercing end 18, and opposedupstanding sidewalls 20. Referring toFIG. 2 ,sidewalls 20 may angle outwardly fromblade 14, such by an outward bend of between 10 and 45 degrees. Assidewalls 20 extend upward and outward, it is easier to remove soil fromblade 14 during digging. Getting the dirt out of buckets or blades is a particular concern in wet clay or sticky mud. If wet clay or mud is being dug, it may also be preferable to haveshorter sidewalls 20. To improve the ground piercing capability ofblade 14,teeth 22 may project forward fromground piercing end 18. Referring again toFIG. 1 ,blade 14 has a forward orientedbend 24 at an angle of 20 degrees, but preferably between 15 degrees and 25 degrees. As depicted,sidewalls 20 slope downwardly frombend 24 toground piercing end 18, such thatsidewalls 20 are negligible atground piercing end 18. Bend 24 is spaced fromground piercing end 18 approximately one third of the way alongblade 14. The length ofblade 14 fromattachment end 16 toground piercing end 18 is greater than five times the width ofblade 14 betweensidewalls 20. - Operation:
-
Excavator bucket 10 is attached to a prime mover, such as a back hoe, by mounting 12. -
Excavator bucket 10 is inserted and moves through the ground based primarily on the horizontal pulling force pulling toward the prime mover (not shown) to provide the necessary force to excavate. The pulling force of the excavator moves material intoexcavator bucket 10 asblade 14 moves horizontally along the length of the ditch. It is to be noted that this is a horizontal force and does not use a tip radius or curl force, as do other buckets. Teeth 22 help groundpiercing end 18 to break and pass through the soil. Bend 24 assists in moving soil into and upward alongexcavator bucket 10 fromground piercing end 18 towardattachment end 16. - Once
excavator bucket 10 is filled,low sidewalls 20 which are tilted outwardly allows for easy cleaning ofexcavator bucket 10 in most, if not all soil conditions. - While
excavator bucket 10 may be made in any size, it is preferred that it be made long and narrow. The desired length will depend upon the depth of ditch or trench being excavated. - It is preferred that the length of
blade 14 be selected to enable excavator bucket to reach the desired depth for the trench without mountingplate 13 for the quick attached assembly entering into the ditch. This allows the trench to be much narrower, perhaps as much as one third of the width of trenches dug with conventional excavator buckets. - Variation:
- Referring to
FIG. 4 , instead ofblade 14 having asingle bend 24 as depicted inFIG. 1 ,blade 14 could also have a curvature (continuous bend) that begins atattachment end 16 and continues untilground piercing end 18, or that includes a substantial portion ofblade 14. If this were done, it would be a tangent taken at a point partway alongblade 14 that would be at 45 degrees, and a tangent taken nearground piercing end 18 that would be at 20 degrees. - In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
- It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
