Description

Bucket Assembly {BUCKET FABRICATION}

The invention relates to buckets and in particular buckets for attachment to a boom attachment, such as a boom attachment of a vehicle.

Most preferably the present invention relates to a bucket fabrication or assembly ("bucket assembly") suitable for use in a back hoe machine or excavator.

The present invention ensures that not only the potential savings of material (usually steel), but also that the performance of the bucket assembly suitable for use as a back hoe bucket is not degraded or rather improved. do.

The present invention provides that the fabrication can be made of plate steel, optionally some cast members (eg, a hitch attachment device, cutting plate) ensure that it can be made by combining a cutting plate).

Thus, the "plate" referred to herein is cast or formed from sheet material as well as plates cut from a flat sheet of plate metal within the range of plates. Whether partitioned or otherwise formed, including compartments or other forms. However, it is desirable that all references to "plate" relate to the expansion of a material having a thickness much thinner than at least some other dimensions.

The present invention ensures the ability to use different types of different parts in the fabrication of the bucket assembly, in which the bucket assembly uses less steel and / or parts than prior designs. Although it is a simple welded construction for minimizing the use of these materials and materials, it provides a higher strength or sufficient strength.

The present invention is directed to this.

In one embodiment of the invention, a bucket assembly for a back hoe or excavator is at least bordered by end plates or end plate sets that are at least spaced apart. A bucket defining a cavity, a cutting edge plate, and one or more other spanning plates spanning the end plates or sets of end plates. (Optionally) at least one rib at least substantially parallel or substantially transverse to the arrangement of the end plates or end plate sets inwardly of the cavity of the bucket or More ribs) and a hitch assembly on the bucket for attachment to a complementary boom attachment. A having, an angle plate extends to the top of the bucket, defining a hollow rigidifying form with the or any spanning plate (s). So as to span each of the end plates, or the plate of each of the end plate sets, and the connection assembly is partly attached or fixedly attached directly or indirectly to the angle plate.

As used herein, the term "an angle plate" refers to a hollow beam across the bucket that relies in part on an underlying separate or integral plate. ) Or one or more plates (if one or more plates cooperate with each other) that can at least partially define.

The end plate (s) may be spread outward toward the front of the bucket.

Preferably the cut edge plate does not define or have a tooth, but may also define or have a tooth.

The plate (s) spanned between the end plates or end plate sets are preferably less thick than the or such end plates, not only at each end associated with the cut edge plate, but also at the cut edge plate itself.

A spanning rib or bar to the outside is secured to the wrap or spanning plate (s) and such fastening ribs or bars are (eg, mutually spaced apart). It is desirable to have a portion of the connector assembly secured to side by side ears supporting a pair of axes.

In one embodiment, the quick hitch assembly is partly fixedly and indirectly attached to the angle plate, wherein the quick hitch assembly is pivotally transverse to the spanning axis of the angle plate. a pivot).

A piston or a carried carriage to conform the bucket to a portion of the pivot that includes a connection assembly for attachment to a complementary boom attachment. It is desirable to have

At least a portion of the structure in which the quick hitch is pivoted in a pivoted form preferably covers at least one rib.

The connector assembly preferably includes a pair of plates spaced apart from each other, wherein the connector assembly includes a pair of plates spaced apart from each other, the pair of plates extending transverse to the interlocking axis of the angle plate and such interconnection of the connector assembly. The spaced apart plates move between each of which is laterally engaged by the attachment of the auxiliary boom attachment, such as two pins, axes, and the like.

In a non pivoted form of the quick connect assembly, the plates of spaced apart plates preferably each cover a rib.

The angle plate is a folded plate or "L" shaped plate that forms the top of the bucket when in operation and is normalized to the plate on which the angle plate is disposed (preferably) (Preferably) the other arm having the forward facing arm of the angle plate at 25 ° with respect to the latching plate of the bucket inclined rearward from the front while the other arm is preferably at an angle of approximately 55 °.
