Definitions

  • the present invention relates to improvements in or related to quick hitches for excavators.
  • arrangement is a technical term which means a feature, or combination of features, (usually with a given purpose).
  • a 'measuring arrangement' is a feature or features, to facilitate measuring.
  • a 'holding arrangement' is a feature or features, to facilitate holding.
  • 'feature' is a broad term that includes within its scope any feature under the Sun.
  • a feature may, for example, be an element, body, member, or may even be an aperture (ie opening/hole or the such like).
  • the term 'holding feature' includes within its scope, for example, any element, body, member, or even aperture, to facilitate holding.
  • a 'feature' may also be a 'part' of a broader feature; for example, if a part of an invention is disclosed/claimed as comprising a 'padding feature', this does not limit the padding feature to being a separate feature that is added to the invention (eg a sponge element, adhered to the invention); the invention, for example, may have a part made of sponge, or have an inner sponge (or soft) layer- in such a case, if that part of the invention is clearly of a material/nature that provides padding, then this falls within a scope of what is defined in the present application as a 'padding feature'.
  • Standard excavator quick hitches are designed to mimic (and facilitate) natural position of how a bucket attachment is arranged, with the bucket faced towards the excavator. If the bucket is reversed in the other direction, the hydraulic bucket cylinder of the excavator tends to already be 80% retracted, which restricts movement of the bucket. This tends to mean the bucket cannot scoop, or carry liquid concrete whilst its dipper arm/stick is close to the excavator.
  • Japanese patent application 2003/213720 describes a bracket which is capable of receiving a hydraulic breaker and a bucket attachment. Both the hydraulic breaker and the bucket can be installed on the bracket at the same time and the bracket can be attached to an earth moving machine body.
  • the present invention provides an excavator quick hitch comprising a quick hitch body, the body comprising: a first angle mounting position arrangement for attaching an excavator attachment in a first angle position; and a second angle mounting position arrangement for attaching the same excavator attachment in a second angle position; wherein the first and second mounting position arrangements are able to hold two different excavator attachments simultaneously for use.
  • an excavator quick hitch 10 comprising: a quick hitch body 12, the body 12 comprising: a first mounting position arrangement 14 for attaching an excavator attachment 18 in a first position; and a second mounting position arrangement 16 for attaching the, or an alternate, excavator attachment in a second position.
  • the first mounting position arrangement 14 and second mounting position arrangement 16 are provided by way of a three attachment point arrangement, wherein the centre attachment point is used as part of the first and second mounting position arrangement.
  • a first attachment point 501, second attachment point 502, and third attachment point 503 are clearly shown.
  • a bucket attachment shown mounted downwards, shown in dashed lines What is being suggested in this Figure is that the bucket attachment shown can be mounted in either of the two positions. It is shown mounted substantially horizontally, but the dashed line version of the bucket is intended to suggest/show it can also, if so desired, be removed, and mounted in the downwards (lower) mounting position.
  • Fig. 1 shows the significant potential benefit(s) of the second position.
  • the (lower) bucket attachment 18 mounted to the first mounting position arrangement 14 is shown in a standard orientation, faced towards the excavator (not shown). This is a useful position for scooping, for example.
  • the angle of the bucket attachment is very limited; for example, an operator would have to extend the arm of the excavator significantly in order to use the lower attachment position for scooping, (or especially for carrying) with the bucket attachment.
  • standard quick hitches wherein there is only one such mounting position arrangement (eg the lower mounting position) may be very limited/restricted in movement and/or position and/or operation of an attached attachment (such as a bucket attachment).
  • Bucket attachment(s) 18 are simply shown by way of example only, and any other attachment(s) such as the rock breaker attachment 20 shown in Figure 4 may be used).
  • attachment point 501 and 502 in the example, form the first mounting position arrangement 14 (which, in the example, is a downward (lower) mounting position arrangement). It is also clear how attachment point 502 and 503, in the example, form the second mounting position arrangement 16 (which, in the example, is a substantially horizontal ((bucket) carrying) position, wherein the bucket (or any other excavator attachment) can carry a load, the term 'load' being an extremely broad term including within its scope any matter and/or thing.
  • the matter could be, for example, solid (such as rock, for example).
  • the matter could be, for example, a fluid.
  • the first mounting position arrangement 14 and second mounting position arrangement 16 are provided by way of a three attachment point arrangement, wherein the centre attachment point 502 is used as part of the first and second mounting position arrangement.
  • the first mounting position arrangement and second mounting position arrangement may be provided by way of a four attachment point arrangement.
  • a first attachment point 601, second attachment point 602, third attachment point 603, and fourth attachment point 604 are clearly shown.
  • bucket attachment(s) 18 are shown in the first mounting position, and the second mounting position, here shown in a scooping position/orientation, although any excavator attachment shown in the present application, (whichever orientation it is shown mounted in), (and in fact any excavator attachment), may be either mounted in the standard, or reverse/inverse, position, and may be provided claimed in either/any orientation.
  • the middle two (ie 602, 603) of the four attachment points may be usable as a third mounting position arrangement 22. This is denoted/shown by the dashed depiction of a bucket attachment 18 in Fig. 3 , shown mounted in the third mounting position, via attachment points 602, 603.
  • the second mounting position arrangement is substantially at 90 degrees to the first mounting position arrangement. This is shown in all the examples shown.
  • the term 'substantially' here means within twenty five degrees of 90 degrees- ie if the first mounting position is a directly downward mounting position, preferably the second mounting position (or any alternate mounting position, which therefore could be called the second mounting position) is between 65 and 115 degrees difference in angle from the first mounting position.
  • first mounting position arrangement and the second mounting position arrangement may be possible for holding different excavator attachments, simultaneously, for use.
  • Several examples of this are shown or suggested in the Figures.
  • Fig. 4 wherein a bucket attachment 18 is shown in the first mounting position, and a rock breaker attachment 20 is shown in the second mounting position.
  • an excavator can be operated, with the operator operating the rock breaker attachment to break rock, and then operating the bucket attachment to clear the rock/debris that has been broken by the rock breaker, without ever needing to change/mount attachments during the operation (which would otherwise be required if only one mounting position arrangement were available, and therefore only one attachment usable at a time).
  • This can save a lot of time and labour in operation of an excavator.
  • the first mounting position 14 arrangement holds an excavator bucket attachment 18
  • the second mounting position arrangement 16 holds an excavator rock breaker attachment 20.
  • the second mounting position arrangement may be an upright bucket carrying position, where the top (upper) mounting positions are, for the sake of the present application, considered to be upright bucket carrying positions. This is clearly shown in Fig. 1 , Fig. 2 , and Fig. 5 .
  • the first mounting position arrangement (or any of the mounting position arrangements provided) preferably provides a downward mounting position. This is shown clearly in Fig. 1 , Fig. 2 , Fig. 3 , Fig. 4 and Fig. 5 , all of which show or denote that an excavator attachment (eg a bucket attachment, or any other excavator attachment) can be mounted downwards, via the quick hitch/quick coupler 10.
  • the quick hitch body 12 may allow for or provide a third mounting position arrangement.
  • a third mounting position arrangement An example of this is shown in Fig. 3 .
  • the quick hitch may comprise a third mounting position arrangement, not limited to the example of Fig. 3 , wherein the third mounting position arrangement uses attachment point(s) from the first and second mounting position arrangement.
  • the third mounting position arrangement may comprise its own attachment point(s), not using attachment point(s) from the first and second mounting position arrangement.
  • the attachment points provided in the present application are provided by way of example, and the mounting position arrangements may use/comprise any mounting/attachment arrangement/means to facilitate mounting/attaching an excavator attachment(s).
  • the mounting position arrangement examples shown in the drawings tend to comprise two attachment points, it is feasible (especially if a bespoke excavator attachment (eg bespoke bucket attachment) is provided/used with the quick hitch) that the or a mounting position arrangement(s) may, for example comprise more than one attachment point to facilitate attachment, or may, for example, comprise only one attachment point.
  • a (possibly bespoke) excavator attachment such as a bucket attachment, for example
  • a (possibly bespoke) excavator attachment may be provided that has a surface (or any point) configured to 'lock' (or attach in any way) to a surface (or any point) of the or a mounting position arrangement, perhaps thus not requiring two (or more) attachment points, but instead locking directly from surface (or any point) of the excavator attachment to surface (or any point) of the quick hitch/mounting position.
  • the mounting position arrangements may comprise two attachment points (as shown in the example Figures).
  • One of the intents of this is to allow for standard excavator attachments (eg such as bucket attachments) already readily available, and used/owned by many excavator owners and/or operators, to be usable with the quick hitch, without requiring bespoke excavator attachments.
  • the quick hitch mounting position arrangements preferably allow for a standard excavator attachment (eg bucket attachment) to be attached/mounted.
  • Fig. 1 what is shown (by way of example) is shown comprising a bucket cylinder 26; a bucket link 28; a tipping link 30; a dipper arm/stick 32; a lifting eye 34; and a bucket (or any excavator attachment) release mechanism 36 (ie an attachment release mechanism 36).
  • the example attachment release mechanism 36 is shown provided at a side of the quick hitch 10 (and thus body 12), but may be provided anywhere about the body 12 of the quick hitch (for a manual type release mechanism), or alternatively an automated release mechanism may be provided, which may be controlled by the operator (eg from inside a vehicle body of an excavator). Any or all of the features shown may be provided.
  • the bucket 18 in Fig. 1 (shown in the substantially horizontal mounting position), is shown in a reversed bucket position.
  • the dashed bucket 18 of Fig. 1 is shown in a reversed bucket position.
  • the same excavator attachment can be used in either the first, or the second, mounting position. This can be useful, for example, in that having the two mounting positions allows the bucket (and/or a bucket hydraulic cylinder) optimal freedom of movement, whether the bucket is facing the excavator, or facing away from the excavator.
  • different excavator attachments 18 can be used on either of the mounting position arrangements.
  • Fig. 2 is a view of the quick hitch shown in Fig. 1 from a reverse side angle, but with the bucket 18 shown in a standard position on the lower position arrangement.
  • the quick hitch shown in Fig. 1 and Fig. 2 all features are simply the same, shown from the reverse angle (ie preferably the quick hitch 10 is symmetrical), the features are not all numbered since they are clearly the same features as shown (and numbered) in Fig. 1 .
  • the quick hitch is symmetrical, although it is feasible the quick hitch may be provided/built in a way that is not symmetrical. It may, feasibly, be close, but not exactly, symmetrical, when viewed from a side angle.
  • Fig. 3 it is shown how there can be three mounting position arrangements. In the example, this is achieved via a four attachment point arrangement, wherein the middle two attachment points form (or are used to form) the third mounting position arrangement. Thus it is shown the same (or an alternate) excavator attachment can be used via the plurality of mounting position arrangements. (The four attachment point arrangement providing a third mounting position arrangement is optional).
  • FIG. 4 there is shown a similar quick hitch 10 as shown in Fig. 3 , now showing a bucket mounted (downwards) in the standard bucket position via the first mounting position arrangement, and a rock breaker attachment mounted via the second mounting position arrangement (preferably substantially horizontally, as shown).
  • two excavator attachments can be used simultaneously via the quick hitch.
  • a rock breaker attachment attached in the top mounting position, and a bucket attachment attached at the bottom (lower) mounting position.
  • an excavator 40 which comprises the quick hitch 10.
  • the excavator is shown comprising a vehicle body 42.
  • the vehicle body 42 is shown, in the example, comprising an operator's/driver's area 44, and a drive element 46 (which is usually provided by way of a track, but may feasibly comprise wheel(s), or any other drive element).
  • the excavator 40 is shown comprising what is generally termed, for the present application, an arm 48, which is depicted in crude terms for representational purposes only.
  • the arm is shown extending towards the quick hitch 10.
  • a quick hitch 10 from a side perspective view, wherein the first mounting position arrangement 14 and second mounting position arrangement 16 are provided by way of a three attachment point arrangement, wherein the centre attachment point 502 is used as part of the first and second mounting position arrangement.
  • the centre attachment point 502 is used as part of the first and second mounting position arrangement.
  • a bucket link attachment arrangement 50 to facilitate attachment to a bucket link (the example shown comprising two (or any amount of) excavator bucket link pin connection position (s)); a dipper arm/stick attachment arrangement 52 to facilitate attachment to a dipper arm/stick (the example shown comprising two (or any amount of) excavator dipper arm/stick pin connection position (s)); a primary locking arrangement for both mounting position arrangements (comprising, in the example, a shown primary locking feature 54); a secondary locking arrangement for the first (lower) mounting position arrangement (comprising, in the example, a shown secondary locking feature 56); and a secondary locking arrangement for the second (upper/top) mounting position arrangement (comprising, in the example, a shown secondary locking feature 58).
  • a bucket link attachment arrangement 50 to facilitate attachment to a bucket link
  • a dipper arm/stick attachment arrangement 52 to facilitate attachment to a dipper arm/stick
  • a primary locking arrangement for both mounting position arrangements comprising, in the example, a shown primary locking feature 54
  • FIG. 7 there is shown a quick hitch 10 from a side perspective view, wherein the first mounting position arrangement 14 and second mounting position arrangement 16 are provided by way of a four attachment point arrangement.
  • the first mounting position arrangement 14 is shown comprising attachment points 601 and 602; the second mounting position arrangement 16 is shown comprising attachment points 603 and 604 (as previously shown/described).
  • Attachment points 602 and 603 also form a third mounting position arrangement (as described (and shown) particularly with reference to Fig. 3 ).
  • a bucket link attachment arrangement 50 to facilitate attachment to a bucket link (the example shown comprising two (or any amount of) excavator bucket link pin connection position (s)); a dipper arm/stick attachment arrangement 52 to facilitate attachment to a dipper arm/stick (the example shown comprising two (or any amount of) excavator dipper arm/stick pin connection position (s)); a primary locking arrangement for the first (lower) mounting position arrangement (comprising, in the example, a shown primary locking feature 60); a primary locking arrangement for the second (upper/top) mounting position arrangement (comprising, in the example, a shown primary locking feature 62); a secondary locking arrangement for the first (lower) mounting position arrangement (comprising, in the example, a shown secondary locking feature 64); and a secondary locking arrangement for the second (upper/top) mounting position arrangement (comprising, in the example, a shown secondary locking feature 66).
  • ('Locking arrangement(s)' may
  • Fig. 7 can allow for simultaneous mounting (and usage) of two separate excavator attachments (as shown, for example, in Fig. 4 ).
  • the term 'body' is a broad term, and it is feasible the body 12 of the quick hitch may be provided, for example, in multiple parts, coming together to form the quick hitch (and thus to form the quick hitch body), or as one part.
  • the part(s) of the quick hitch body that comprise the arrangements to facilitate attachment to the bucket link and/or dipper arm/stick are provided as a separate part(s), which is then attached (preferably by welding) to the part(s) of the quick hitch body that comprise the mounting position arrangements, nevertheless, the parts, together, are considered to be part of the quick hitch 10, and thus part of the quick hitch body 12.
  • the quick hitch body may be provided by way of multiple parts, coming together to form the quick hitch body.
  • the quick hitch body may be claimed as a quick hitch unit, and the terms 'body' and 'unit' are seen as interchangeable.
  • the quick hitches shown in Fig. 6 and Fig. 7 shown removed from/not attached to the excavator arm, thus show the quick hitch 10 being removably attachable.
  • quick hitch 10 may be provided in many different sizes.
  • a quick hitch comprising four attachment points (as shown, for example, in Figs. 3 , 4 and 7 ), with both primary and secondary locking mechanisms disengaged on the first mounting position, the machine operator will at first pick up the first attachment using a mounting/attachment point 601 on the bottom (lower) first mounting position arrangement of the quick hitch with one of the pins of the attachment depending on preferred orientation then will by moving the machine allow the excavator attachment to gravitate towards the second mounting/attachment point 602 of the (lower) first mounting position arrangement. Once the correct position has been obtained the machine operator will either manually or automatically engage the locking mechanism depending on the type of quick hitch, securing the first excavator attachment to the first mounting position arrangement of the quick hitch.
  • the machine operator will pick up the second excavator attachment using the top mounting point 604 on the top (second) mounting position arrangement of the quick hitch with one of the pins of the attachment depending on preferred orientation, then will by moving the machine allow the excavator attachment to gravitate towards the second mounting point 603 of the second mounting position arrangement.
  • the operator will either manually or automatically engage the locking mechanism (s)/arrangement(s) depending on the type of quick hitch, securing the second excavator attachment to the second mounting position arrangement of the quick hitch.
  • both attachments are secured, the operator can choose to use whichever attachment is required by using the excavator bucket cylinder to rotate between them. If the machine operator chooses to connect just one attachment to the quick hitch whilst following the mounting procedure set out above, he/she is free to do so, as both mounting position arrangements have independent locking arrangement(s) /mechanism(s) (which may be automatic and/or semi-automatic and/or manual).
  • a quick hitch comprising three attachment points (as shown, for example, in Figs. 1 , 2 , 5, and 6 ), with both primary and secondary locking mechanisms disengaged the machine operator can choose to switch between the first mounting position arrangement and the second mounting position arrangement.
  • the machine operator ideally picks up the attachment using the back attachment point 501 of the first mounting position arrangement on the bottom of the quick hitch with one of the pins of the attachment depending on the preferred orientation and by moving the machine allow the attachment to gravitate towards the common attachment point 502 at the bottom front of the quick hitch.
