Definitions
- This invention relates to buckets and in particular buckets for attachment to an attachment feature of a boom of, for example, a vehicle.
- Bucket assembly a bucket fabrication or assembly suitable for use with a back hoe machine or excavator.
- the present invention has recognised a potential saving in material (usually steel) as well as no drop off in performance or indeed an improvement in performance of a bucket assembly suitable for use as a back hoe bucket.
- the present invention recognises that fabrication from plate steel, optionally in conjunction with some cast members, (e.g. of for example a hitch attachment device, a cutting plate or the like), can be made.
- some cast members e.g. of for example a hitch attachment device, a cutting plate or the like
- plate includes within its ambit not only plates cut from a flat sheet of plate metal but also a contoured or other shape whether formed from sheet material or cast or however otherwise formed. It is however a preferment that any reference to “plate” is in respect of an expanse of material having a thinness very much less than at least some of its other dimensions.
- the present invention recognises an ability to utilise a variety of different components in • the fabrication of a bucket assembly which, in preferred forms, uses less steel than with previous designs and/ or preferably provides a higher or adequate strength notwithstanding a simple welded construction which tends to minimise components and material useage.
- the invention is a back hoe or excavator bucket assembly having a bucket defining cavity bounded by at least spaced end plates or end plate sets, a cutting edge plate, and one or more other plates spanning ("spanning plate(s)") between the end plates or end plate sets,
- a hitch assembly on the bucket for attachment to a complementary boom attachment, wherein an angle plate extends above the bucket to span to each of the end plates, or to each of a plate of the end plate sets, to define, together with the or a spanning plate(s), a hollow rigidifying form, and wherein the hitch assembly is frxably attached directly in part, or indirectly in part, to said angle plate.
- angle plate includes one or more plate (coacting if more than one plate) able to define at least in part a hollow beam transverse of the bucket reliant in part of an underlying separate or integral plate.
- the end plate (s) can splay outwardly towards the front of the bucket.
- the cutting edge plate does not define or carry teeth, but may do so.
- the extent of the hitch assembly in the directions parallel to the end to end axis of the bucket is very much less than the end to end distance. For example, much less than 50%. Preferably about or even less than 25%.
- At least one rib is present.
- the spanning plate(s) is a single plate acting as a wrap of the rib(s). In some embodiments it can have some lapping of its plates.
- the angle plate is welded at each end (at least in part) to a complementary edge of an end plate and the spanning plate(s) is butt welded (at least in part) to those end plates at each end below the edge.
- spanning plate(s) between the end plates or end plate sets are of less thickness than the or that end plate at each end associated with the cutting edge plate as well as the cutting edge plate itself.
- a spanning rib or bar exteriorly is fixed to the wrap or spanning plate(s) and preferably that spanning rib or bar has part of the hitch assembly fixed thereto (e.g. parallel ears that support a spaced pair of shafts).
- the quick hitch assembly is fixably attached indirecdy in part to said angle plate, there is a pivot in the hitch assembly that is transverse to the spanning axis of said angle plate.
- hitch assembly preferably there is a carried ram or carried rams to orientate the bucket relative to that part of the pivot including hitch assembly for attachment to a complementary boom attachment.
- the structure from which the quick hitch is pivoted overlies at least one rib.
- the hitch assembly includes a pair of spaced plates that extend transversely of the spanning axis of said angle plate and such spaced plates of the hitch assembly carries there between two pins, shafts or the like each to be engaged laterally by the attachment of a said complementary boom attachment.
- a plate of said spaced plates each overlies a rib.
- the angle plate is a folded plate or a fabricated "L" shaped plate with respect to the plate on which it rests and forming the top of the bucket when in an operational condition, (preferably) has the forward facing arm of the angle plate at 25° to the bucket spanning plate angling backwards from the front whilst (preferably) the odier arm is at an angle of about 55° angling back towards the rear of the bucket.
- the top of the spanning plate is substantially planar and is positioned horizontally, preferably the cutting edge plate and preferably part of the spanning plate(s) into which or to which it attaches, or which it overlies in part, is at 30° to the horizontal.
- the pin or shaft spacings are at an angle of 8° with respect to the spanning plate datum (being, within about 3°, the planar substantially horizontal region of the spanning plate at the top of the bucket cavity).
- the invention is a back hoe of excavator bucket assembly having a bucket defining cavity bounded by at least spaced end plates or end plate sets, a cutting edge plate, and one or more other plates spanning ("spanning plate(s)") between the end plates or end plate sets,
- a hitch assembly on the bucket for attachment to a complementary boom attachment, wherein a hollow beam extends between each of the end plates, or to each of a plate of the end plate sets, (optionally in conjunction with a spanning plate), to define a hollow rigidifying form above said bucket defined cavity, and wherein the hitch assembly is fkably attached direcdy in part, or indirectly in part, to said hollow beam.
- the invention is a bucket assembly as hereinafter described with reference to one or more of the accompanying drawings.
- - A The invention also consists in uses and combinations of such equipment.

- Figures 1 through 8 show a form of wide bucket for association with a quick hitch at the end of a boom of a vehicle, (e.g. a back hoe).
- a quick hitch can be of any suitable type but is preferably one of a kind disclosed in one or more of our patent specifications or as marketed by us as the J B QUICK HITCH COUPLERTM.
- a feature of the invention is a provision of a spanning member 1 as a wrap around of spaced ribs 9 and the association therewith with of weld connected end plates 2 and 5.
- the wrap 1 can be of steel (for example, a thin plate steel) reinforced by a spanning bar of plate steel 8 and reinforced at its top by the angle section (rib panel) 7.
- the cutting edge plate 3 (preferably untoothed) is connected or laps at least in part, or receives, the wrap plate 1.
- angle section 7 relates to the top of the thicker sectioned end plates 5 and 6 (side styles) and preferably in part, part of the lesser thickness plates 2.
- welding at the end of the angle section 7 is to the top of the members 5 and 6 respectively as well as of the wrap to the edge of the members 2 and into a butt weld with the members 5 and 6 respectively.
- Supporting the cutting edge as well as the wrap and the overlying angle section 7 is the rib pairing, preferably welded to the spanning wrap plate.
- the hitch arrangement itself with its shafts 4 is preferably carried by the plates 10 ("ears") each of which directly overlies a rib 9 and is welded to the angle section 7, optionally a forward part of the wrap, the behind angle section 7 part of the wrap and to the spanning bar 8.
- a feature of the embodiment of Figures 1 to 5 is the angling.
- the angle alpha is about 30° to the horizontal as shown in the drawing.
- angles beta and gamma respectively for the front facing and rear facing arms of the angle section relative to the plane shown by the broken line or the horizontal which may differ by up to 5° (e.g. about 3°).
- the relativity of the angles beta and gamma are about 25° ( ⁇ 10°) and about 55° ( ⁇ 10°) to that plane shown by the broken line in Figure 4.
- the shaft axes are angled relative to that same broken line by an angle of about 8° with the rearmost shaft higher over a centre to centre expanse of, for example, about 230mm.
- the rib spacings is preferably of the order of about 160mm.
- FIG. 9 through 14 is of a preferred form which varies from those previously disclosed in that there is provided a pivot axis on the shaft 39 with the top part of the hitch being much as previously but of course with the ability to be rotated relative to the bucket assembly and the mounting plates 33 and 34 under the action of the hydraulic ram.
