Abstract
The present invention relates to an improved tool of the type used to engage and penetrate hard surfaces, in particular hard surfaces which would otherwise damage or decrease the lifespan of conventional wear parts. The tool may be in the form of a ripper boot, a bulldozer blade, a grader blade, or other similar equipment, and achieves this by having one or more high tensile inserts welded to a tip or along a first contact edge thereof.
Description
A Si:RFACF. ENGAGING TOOL INCLUDING HiGfi TENSILI; INSERTS
The present invention relates to surface engaging tools and, in panicular, to the use of high tensitc inserts which are braze welded to the tip ur contact edge of such touls for increasing their strength and lifespan making them particularly suitable for use when excavating extrentely hard rock.
BACKGRL)UNI] OF THE INVENrTION
The present inventor is the owner of a number af co-pending patent appiications including PCTIAU2006d0012I8 and AU20069D4612, relating to ripper boot irnprovements, for particular use witli bulldozers used to excavate hard rock to iocate precious steutes such as opal. In ptnicuiar, the inventor has been in volved in improving the wear resistwtce of such boots by using replaceable high teasile tips, improving their mounting meuns within the boot, as well as altering their angle of attack.
The inventor has realised that the use of high tensile tips such as tungsten need not be limited to ripper boots unly, and that such matcrial could be used in other smail to large scale surface engaging equipntent. A problem to date has been in attaching and securing high tensile material to the tip or alung the contact edge of such tools. As those skilled in the art would realise, surface engaging tools are typically made of steel and therefore welding of any material to a tip or end thereof w=ill cause weakening of the surrounding tnetal, and under heavy impact conditions, the tool becomes prone to fracture at these weak spota. Tror this reason, the use of welded on high tensile tips on such tools has not been adapted in the wear parts industry.
It is therefore an object of !he present invention to overcome this problem or to at least ptovide the public with a useful alternative.
It is a iurther object of the present invcntion to provide a surface engaging tool capable of engaging extremely hard grnund through use of at least one high tensile insert welded to a contact surf.ice thereof.

1)E,Sf'1tlPT1QN OF THE P'REFERR$D F.Nff3Oi)IIVIFNTS
The following detailcd description of the inventiun refers to the accotnpanying drawings. Aithough the de.criptiun includes exemplary embodiruents, other embodiments are poasible, and changes may be made to the embodiments described without departing from the spirit and scope of the invent~on. Wherey-er possible, the same referenco nurnbcrs will bo used throughout the drawings and the following deseription to refer to thc sanie and likc pwrts.
The present invention relates to ground engaging tools 10 having high tensilc inserts 12 welded along a contact edge 14 thereof. Reference to a "contact edge"
herein refers in most cases to an edge of the tool which is the tirst to contact the ground or surface.
Iigures 1-3 illustrate the invention when applied to ripper boots 10a, Figure illustrates the invention when applied to an alternate ripper boot M. Figtue S
illustrates the invcntion when applied to a grader blade lOc, and Figtue 6 illustrates ahG
invention when applied to a bulldozer blade I Od. It is to be understood that the invention could equally wcll be applied to any other ground engaging tool, or any tool requiring high tensile contacl edges.
Referring firstly to Figures 1-3, the ripper bixk I Oa includes a carrier section 16 which is hollm- and conformed to fit over a ripper boot tyne (not shown), and a solid engaging section 18 which includes a contact edge 14. Four slots 20 line the edge 14 and un:
shapcd to receive high tensile inserts 12 which are preferably secured therein by brnnze welding so that they protrude slightly nutwandly from the contact edgc 14.
This is to ensurc that the high tensilc material, prcfcrably tungsten, is the first material that contacts the surface to be broken up during operation of the boot. The result is a surfac:e engaging tool of superior strength characteristics and which may be used to rip through extremely hard surfaces, for example, such a tooi would be suitable in the ripping of hard sandstone.
According to the embodiments shown, each insert 12 is of a fnisto-triangular shape having a rectanguiar cross-sectiun along its height, the insett being welded to Ute tool so that the head of th.e frusto-triangle is directed outwardly. ft ls to he understood that the shape of the inserts are not to be limited to frusto-triangular. The shape of the insert can be altered to suit the tool, or the application. For example, it may he that in some environments, a rounded or pointed head is mre suitabte.
'I'he carrier section 16 is typically held in place by utiiisation of a pair of co-axially aligned retaining holes 22 and 24 located in opposed side walls 26 and 28 of the carrier section 12 respectively. A retaining pin (not shown) is adapted to extend through the holes 22 and 24 and through an aperture (not shown) associated with the available tyne.
It is to be understood that the carrier 12 may he conformed to fit any available ripper boot or loader bucket shank, and that the present immttion is nnt intended to be limited to only this form of attachment.
Figure 4 illustrates an altemate ripper boot I Ob including substantially the same features as ripper boot 10a, except it is thinner and only accommodates two inserts 12 at a tip therrof. Figure 5 illustrates a conventional grader blade I Oc comprising a longitudinal Wdy 26 that is curved along its height. The grader blade I Oc is typically associawd with a powLred machinc (not shown) which drivcs the blade, and includes a bottom edge 28 attached to the body 26 by bolts 30, and used to gradc or level a ground surface. It is this bottom edge 28 that inclttdes a plurality of welded on high tensile inserts 12. A conventional bulldozer blade I Od is shown in 1~'ip re 6, and similarty, a plurality of high tensile inserts 12 lines the lower edge 32 of the blade lOd. The blade IUe in this ca4e comprises a longitudinal tray-type body 34 for storing the ground or rubble that has been ripped through contact with edge 32, also bolted to the body 34 using bolts 36. Again, althaugh not shown, the blade l0d is adapted to be moved by a human-operated powered machine.
In order for the tools 10 to maintain their intended physical properties at'ter welding, they tnay need to be subjeoted to t'urther heat tn:atrncnt. Those skilled in the att would realise that welding the inserts 12 in place causes the surrounding metal to heat up and thereby lose some of its important physical properties which ettablc it to withstand strong impact. FLrrther heat lrratntenl.such as LGmpering is thereftxe required to prevent fracture of the metal at weak spots surrounding the welds. The preferred welding mcthod is brttze or bronze welding which involves the depositing of a filler metal 38 such as bronze into the joint between the slot and the insert.
In io far as the ditnensions of the insarts are concenied, it is cstitnated that for ripper boots, they shuuld be within the range of one fifteenth to one tenth the length of the boot. For example, for a ripper boot that is approximately 30cm long, the inserts should be approxintately 2-3cm. An inserr. that is 3cm long would have a+uidth of approximately 4mm.
The number of inserts shuuld be prolxrrlionai to the desired .r=trength characteristies of the tooi, In gencral, for a ripper buot having a contact edge of approximately 8em for example, four inserts could be used which are spaced apart by approximately (cm, as shown in Figure 1.
The prrsent invention therefore provides fnr an improved tool of the type used to engage and penetrate hard surfaces, in particular hard surfaces which would otherwise damage or decrease the lifespan of conventional wear patis. The tool may be in the f<nnt of a ripper boot, a bulldozer blade, a grader blade, or other siniilar equipnient, and achieves this by having one or ntore higlr tensile inserts welded to a tip or along a first contact edge there(if.
Those skilled in the art would reaGse the benefit of being able to inerease thc efficicncy and lifespan of wear parts bv including tungsten or high tensile material inserts, particularly in the mining industry in which wear parts ntay require replacement every few hours.
Furthermore, less maintenance is required on the carrying tool during operation which means that the associated machinery does not need to idle so often, saving considerable tinie and expense.
Further advantages and improvemcnts may very w=cll be niade to the present inve-ntion without deviating from its scope. Although the invention has been shown and described in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope and spirit of the invention, which is not to be linutod to the details disclosed herein but is to be accorded the full scope of the clai ms so as to embrace any and all equivalent devices and apparatus.
In any claims that follow and in the summary of the invention, except w=hene the context requires otherwise due to express lAaguagc or tx:cessary implication, the word "comprising" is used in the sense of "including", i.e. the features specified may be associuted with ftuther features in various embodiments of the invention,
