[0001] [0001] This disclosure refers to a bucket and a ground handling device, which includes the bucket. The development also extends to a method of repairing a movable bucket.
[0002] [0002] The revelation refers particularly, but not exclusively, to an excavation bucket. Therefore, it will now be convenient to describe the invention with reference to that exemplary application. For example, the digging bucket can be used on an excavator to dig ditches and longitudinal channels in the ground and to manipulate material in mines and quarries. However, it should be understood that the development is capable of wider application and applies to other buckets and material handling machines. BACKGROUND
[0003] [0003] The reference to the prior art in this specification is not and should not be taken as an acknowledgment or any form of suggestion that the referenced prior art is part of common general knowledge in Australia or any other country.
[0004] [0004] Earth or soil handling machines have wide applications in construction, mining and the like. These machines include excavators, crawler tractors, dredgers, trailed shovels, mobile scrapers and bucket wheels. The buckets have a part that interacts with a bucket handling arrangement on the machine and a bucket-shaped material container. The buckets are demountable on an articulated arm of the machine.
[0005] [0005] An excavator or digging device is used to dig or dig channels and holes in the ground. An excavation can be carried out for a multitude of reasons, including pipe placement, pipe maintenance and repair and also for excavations in general in the ground.
[0006] [0006] Excavators are also used in open pit mining to excavate blast or loose cover terrain and transfer material to dump trucks. Mining buckets can be manufactured by a standard original equipment manufacturer (OEM) or by custom engineering to meet specific site applications such as material type and density. Excavated materials include hard rock, iron ore and coal.
[0007] [0007] An excavator typically comprises a lift or body and a boom that extends from the lift and an arm at a far end of the boom that articulates in relation to the boom. The lift is typically a vehicle that has ground penetrating formations that can move through the ground and can also rotate in the same location on the ground. The support also includes an operator's cabin that is used by an operator to operate the excavator. An excavator bucket is removably mounted on one end of the arm, away from the support. The bucket is maneuvered by a bucket handling arrangement that normally includes a plurality of hydraulic rams to pivot the bucket.
[0008] [0008] An excavator bucket has an upper part of the bucket that interacts with the bucket handling arrangement and a lower section that forms the bucket-shaped material container.
[0009] [0009] The material handling section of earth or soil buckets is subjected to high levels of wear in the normal day-to-day operation and use of the excavator. Some previous buckets are designed to withstand adverse operating conditions and extend their service life as much as possible. For example, some prior art buckets comprise a steel body that is internally coated with wear liners and replaceable wear guards. There is considerable downtime when reinstalling a bucket liner, for example, the manufacturing time would be about six weeks.
[0010] [0010] Eventually, the material handling section will need to be replaced. This means that an entirely new bucket needs to be manufactured. Related to that, there is also a considerable expense. The upper part of the bucket that interacts with the bucket handling arrangement requires high tolerance machining and this is time consuming and expensive. DEFINITION
[0011] [0011] In the specification and claims, the term "comprising" should be understood as having a broad meaning similar to the term "including" and will be understood to imply the inclusion of a whole number presented or step or group of whole numbers or steps, but not deleting any other whole number or step or group of whole numbers or steps. This definition also applies to variations in the term "that you understand", such as "understand" and "understand". SUMMARY OF THE REVELATION
[0012] [0012] The Applicant recognizes that it would be beneficial if the downtime used to replace, repair or recondition worn or damaged linings and buckets could be kept as low as possible.
[0013] [0013] According to one aspect of the development, a bucket is provided for moving soil material, the bucket comprising: a handling section with an assembly arrangement for coupling to a machine; and a cargo section mounted on the handling section, so that the cargo section is separable from the handling section, so that the cargo section can be separated and replaced with another cargo section.
[0014] [0014] The soil material can be any suitable material that you want to excavate and move and includes soil, earth, post-dynamite cover terrain, loose cover terrain, coal, metal ore and the like.
[0015] [0015] The machine on which the bucket is mounted can be any suitable machine used to move earth or soil material and includes excavators, trailed shovels, crawler tractors, dredges, cable shovels, bucket wheels and loaders.
[0016] [0016] The load section can be joined to the welding handling section and can be separable or detachable from the handling section by breaking the weld.
[0017] [0017] Instead, the handling section can be mounted on the handling section by fasteners and can be detached or detachable from the handling section by removing the fasteners.
[0018] [0018] The fastening elements can be rivets, screws or other suitable fasteners.
[0019] [0019] The handling section may include an assembly formation and the loading section may include an additional complementary assembly formation which engages the assembly formation in the handling section to assemble the handling section in the cargo section.
[0020] [0020] The first assembly formation can be configured to comfortably receive the second assembly formation in it and the complementary assembly and assembly formations may have surfaces that are in contact.
[0021] [0021] The mounting arrangement for coupling to a machine can be any mounting arrangement suitable for coupling a ground handling bucket to a machine. Suitably, the mounting arrangement comprises at least one ear plate.
[0022] [0022] According to another aspect of the disclosure, a bucket is provided to move soil material, the bucket comprising: a handling section with an assembly arrangement for coupling to a machine; a cargo section mounted on the handling section, so that the cargo section is separable from the handling section, so that the cargo section can be separated and replaced with another cargo section; wherein the handling section includes an assembly formation, and the loading section includes an additional assembly formation which is complementary to said assembly formation and the assembly formation is configured to receive additional assembly formation therein and the formations mounting and complementary mounting have surfaces that are in contact.
[0023] [0023] The use of complementary mounting formations that are in contact avoids the use of additional connection devices, such as connection plates or other connection devices. Additional plates or connectors may interfere with material handling and / or may be subject to damage during use.
[0024] [0024] The assembly formation can have at least one pendant skirt that overlaps in a comfortable way and rests on a complementary recess at the top of the complementary assembly formation. In this way, the boundary surfaces transfer tensions and forces.
[0025] [0025] The assembly formation or the complementary assembly formation may also have at least one key section and the other among the assembly formation or the complementary assembly formation may have a complementary recess to assist in the correct alignment of the two sections.
[0026] [0026] The loading section can comprise a structure and a plurality of plates mounted on the structure.
[0027] [0027] At least one of the plates can be separable or detachable from the structure, so that the plate can be separated and replaced by another plate. Optionally, each of the plates can be separable from the structure so that each one can be replaced when worn or damaged. This can be compared to conventional one-piece buckets, in which, for example, if a side wall is damaged in use, the entire bucket would need to be replaced.
[0028] [0028] The at least one of the plates can be mounted separably or detachable on the structure by welding and can be separated from the structure by breaking the weld.
[0029] [0029] The structure can have two sides and the loading section can include side plates mounted on each side of the structure.
[0030] [0030] The structure can define at least one support panel that extends between the sides and the load section can include at least one support plate mounted on the structure and that extends through the support panel.
[0031] [0031] The at least one support plate can be separable from the structure so that the support plate can be separated and replaced with another support plate, for example, when worn or damaged.
[0032] [0032] The at least one support plate can comprise two plate elements joined together and the two plate elements can have a different plate thickness or resistivity. This allows the two plate elements to be designed to withstand different forces and loads. This in turn allows a plate element positioned in a high wear area to be designed to have superior resistivity and wear resistance properties to another plate element.
[0033] [0033] In another form, the structure can define two support panels that extend between the sides of the structure and the load section can include support plates that extend through each of the two support panels.
[0034] [0034] The properties of the slabs, such as thickness and wear resistance of the material, can be selected according to the specific requirements of the location.
[0035] [0035] The loading section may comprise a base and a wall extending from the base, and the loading section may also have an open top.
[0036] [0036] The wall may have an upper edge that forms the additional assembly formation that engages the assembly formation in the handling section.
[0037] [0037] The structure can form a mouth through which the material enters and leaves the loading section.
[0038] [0038] The bucket can additionally include a scraper mounted on the structure adjacent to the mouth.
[0039] [0039] The scraper can be separable from the structure to allow the scraper to be replaced by another scraper. This can occur if a scraper becomes worn or damaged or the soil conditions change, so a different scraper is required.
[0040] [0040] In addition, the bucket or excavator can be used in a different application that requires a different bucket design.
[0041] [0041] The bucket can additionally include a plurality of replaceable ground penetrating formations, removably mounted on the scraper and on the structure adjacent to the mouth.
[0042] [0042] Additionally, the bucket can also include a plurality of replaceable corner protection elements removably mounted on the structure at spaced intervals along the sides of the structure.
[0043] [0043] The handling section may include an upper mounting plate and the mounting formation may comprise a skirt that extends away from the upper plate. For example, the mounting plate can be substantially rectangular and the skirt can hang from three sides of the rectangular mounting plate.
[0044] [0044] The mounting arrangement in the handling section can include any suitable support for attaching a bucket to an earth moving machine. Suitably, the mounting arrangement includes a plurality of ear plates for interacting with an external bucket handling arrangement, which protrude from the mounting plate and are separated from each other. Each ear plate can form an opening to receive a pivot pin through which it allows the bucket to be pivoted in relation to the bucket handling arrangement.
[0045] [0045] In accordance with another aspect of the disclosure, a bucket is provided to move soil material, the bucket comprising: a handling section; and a load section mounted on the welding handling section that is separable from the handling section by breaking the weld so that the loading section can be replaced by another loading section, where the loading section comprises a structure and a plurality of plates mounted on the structure by welding, and at least one of the plurality of plates is separable from the structure by breaking the weld so that the plate can be replaced by another plate.
[0046] [0046] Suitably, the bucket is an excavation bucket.
[0047] [0047] The handling section can define an assembly formation and the load section can define a complementary assembly formation that is comfortably received within said assembly formation.
[0048] [0048] The handling section may include a top plate that has a peripheral edge and the assembly formation may comprise a skirt that hangs from the peripheral edge of the top plate.
[0049] [0049] According to another aspect of the disclosure, a handling section is provided for an excavator bucket comprising a substantially rectangular mounting plate with at least one mounting element for attaching to a machine and a skirt that hangs from three sides the mounting plate, where the skirt comprises a mounting formation for mounting on a loading section.
[0050] [0050] The loading section may include a wall that has an upper edge that forms the formation of additional mounting.
[0051] [0051] According to another aspect of the disclosure, a loading section is provided for an excavator bucket, the loading section comprising a base, two side walls, a rear wall, with each wall having an upper edge that defines an open top and forms a mounting formation for mounting in a handling section.
[0052] [0052] The loading section can include two side plates and a support plate, and each of the two side plates and a support plate can be separable from the structure.
[0053] [0053] According to another aspect of the disclosure, a bucket is provided to move soil material, the bucket including: a structure; and a plurality of plates mounted on the structure, at least one of the plurality of plates being separable from the structure to allow the plate to be replaced by another plate.
[0054] [0054] In this way, the plates can be removed and replaced when worn or damaged.
[0055] [0055] At least one of the plurality of plates can be welded to the structure and be separable from the structure by breaking the weld.
[0056] [0056] Optionally, each of the plurality of plates can be separable from the structure, so that all plates can be replaced.

[0058] [0058] The structure can define at least one support panel between the side panels, and the load section can include at least one support plate mounted on the structure and which extends through the support panel, and at least one plate The support plate can be separated from the structure so that it can be replaced by another plate, for example, when worn or damaged.
[0059] [0059] In a way, the structure can define a support panel, for example, which is curved along its length, and a support plate, for example, with a corresponding curve, which extends through the support panel .
[0060] [0060] The support plate may comprise two plate elements joined together, for example, which are welded together, and the two plate elements may have a different thickness or load resistance. This allows the two plate elements to be engaged to support different forces and loads.

DETAILED DESCRIPTION
[0089] [0089] An excavation bucket and an excavator according to this revelation can manifest themselves in several ways.
[0090] [0090] In Figures 1 to 14, reference number 10 refers, in general, to an excavation bucket suitable for use in excavation.
[0091] [0091] The bucket 10 comprises a handling section 12 and a loading section 14 that is mounted on the handling section 12 so that it can be separable, that is, it can be separated, from the handling section 12. This allows the loading section 14 is separated from the handling section 12 and replaced by another loading section. In the embodiment illustrated in Figures 1 to 13, the load section 14 is mounted on the handling section 12 by welding the load section 14 to the handling section 12. Thus, it can be separated from the handling section 12 by any one of the technologies available to cut a weld connection, which includes oxyfuel, gouging or arc grinding torches from compressed air.
[0092] [0092] The loading section 14 has a configuration substantially similar to a box with a base 15 and a wall 16 that extends from the base along three sides. A fourth side is open and defines a mouth 17 for receiving excavated material. Additionally, the loading section 14 has an open top 19 (see Figures 9 and 10).
[0093] [0093] Structurally, the loading section 14 is formed by a frame 22 and a plurality of plates mounted on the frame 22. More specifically, the frame 22 defines side panels on each side of the frame 22 and side plates 24, 26 that extend through the side panels. In addition, frame 22 defines at least one support panel that extends through the rear of the load section between the side panels and a support plate 28 mounted on structure 22 that extends through the support panel.
[0094] [0094] Figure 8 shows an exploded view of bucket 10 with plates 24, 26, 28 separated.
[0095] [0095] The frame 22, in turn, comprises two side frame members 30, which are each on one side of the bucket 10. The frame 22 also includes two transverse frame members, an upper 32 and a lower 34 which extend through the rear of the load section 14 between the side frame members
[0096] [0096] The wall 16 of the loading section 14 has an upper edge 18 which forms a mounting formation which is the peripheral edge formation 20 which further adds to and interacts with a peripheral edge formation in the handling section 12 in a manner that will be described in more detail below.
[0097] [0097] The upper edge 18 of the wall 16 is defined by the upper edge of the members of the side wall structure 30 and the upper edge of the upper transverse element 32.
[0098] [0098] The plates 24, 26, 28 are welded to the frame 22 and can be removed when they become worn or damaged.
[0099] [0099] Bucket 10 additionally includes a scraper 36 mounted on the frame 22 adjacent to the mouth 17. As shown in the drawings, scraper 36 has ground-penetrating teeth 38 to assist bucket 10 in excavating the ground.
[00100] [00100] The handling section 12 comprises a mounting plate 42 that has a skirt 44 around its peripheral edge. The skirt 44 extends away from the mounting plate 42 and forms a mounting formation in the form of a peripheral edge formation 46 that interacts with the additional complementary edge formation 20 in the loading section 14.
[00101] [00101] With reference to Figures 9 and 10, the upper side structure elements are in two parts, an inner element part 50 and an outer element part 52 that are welded together. The inner parts 50 define lateral parts of a peripheral edge formation 20 of the loading section 14. The upper part of the upper frame member 32 defines a rear part of the peripheral edge formation 20 (seen more clearly in Figure 10).
[00102] [00102] The mounting plate 42 is substantially rectangular having four sides and the skirt 44 which is configured to extend circumferentially around the additional peripheral edge formation 20 of the loading section 14. Thus, at least part of the skirt 44 lies overlaps with the formation of complementary peripheral edge 20 to provide a surface for attaching the two sections 12, 14 to each other.
[00103] [00103] Skirt 44 has two sides 44a, 44b and a rear section 40c. Each side 44a, 44b has a dependent key part 48. The external side element part 52 of the loading section 14 has a complementary recess 45. When the two parts are joined, the main part 48 is located within the recess 45 to allow joining simple and precise handling section 12 and loading section 14. The front edge of recess 45 can also provide a support surface when bucket 10 is digging back towards the excavator.
[00104] [00104] The end of the mouth 20m from the peripheral edge formation 20 has a stepped profile, as shown in Figures 9 and 10. The handling section 14 has a front panel 60 that has a flap 62 on both sides which is received by the staggered portion. Again, this helps to locate the two parts together. This is shown in the cross section shown in Figure 6.
[00105] [00105] It will be recognized that, when the two sections 12, 14 are joined, the inner surface of the skirt touches the outer surface of the peripheral edge formation 20. This contact can be seen clearly in the cross section of the Figure
[00106] [00106] Handling section 14 additionally includes a mounting arrangement comprising a plurality of ear plates 64 on mounting plate 42 separated from one another to interact with a bucket handling arrangement on an excavator. Each ear plate 64 defines an opening 66 for receiving a pivot pin from the bucket handling arrangement to allow bucket 10 to be pivoted relative to the bucket handling arrangement. As the structure and function of the bucket handling arrangement for maneuvering and handling a bucket would be well known in the art and are not part of the disclosure, it will not be described in more detail. The machining of the ears 64 is required to be carried out to a high tolerance and is therefore expensive.
[00107] [00107] Figures 11 to 14 show how the handling section and the loading section are welded together. The parts are welded together along an internal 70 and an external 72 weld line. Figure 14 shows the cross section with the contiguous surfaces welded together. It will be recognized that the double weld lines provide a very strong connection between the two sections.
[00108] [00108] Figure 15 illustrates an example excavator that is used with an excavator bucket according to Figures 1 to 14 above.
[00109] [00109] Excavator 80 comprises a support 82 and an articulated member 84 that extends from the support. Support 82 is a movable support that has ground penetrating formations 86 and includes an operator cabin 88. Pivot member 84 comprises a boom 90 extending from support 82 and an arm 92 at a far end of the boom 90 that articulates in relation to boom 90. A bucket 10, like the one described above with reference to Figures 1 to 14, is detachably mounted on one end of the hinge element 84 away from the support 82.
[00110] [00110] In use, bucket 10 is typically used on an excavator 80 like the one illustrated in Figure 15 to excavate and remove material from the ground.
[00111] [00111] When bucket 10 is operational and used for work, handling and loading sections 12 and 14 are attached to each other and operate as a single unit. The loading section 14 is exposed to significantly greater forces than the handling section 12 during typical bucket operation, for example, due to rocks and other materials on the ground. As such, it is prone to wear and damage over time. Therefore, it would be expected to have a shorter service life than the load section 14, which does not withstand the impact of collisions with the material being excavated.
[00112] [00112] When the loading section 14 becomes damaged or worn or requires replacement, the excavator's operation can be stopped and the bucket removed and taken to a workshop.
[00113] [00113] The lower load section 14 can then be replaced by a new undamaged and undrawn lower section 14, which is attached to the original handling section 12 and which is therefore reused. To do this, the original loading section 14 is separated from the upper handling section 12, which involves cutting through the solder connection that secures and secures the loading and handling sections 14 and 12 to each other. This is accomplished with the use of cutting torches or other tools known in the art. As these techniques would be well known to those skilled in the art and are not part of the invention claimed in this application, they will not be described in more detail in this specification. A new undrawn load section 14 is then mounted in the original handling section or in the same section 12, for example, by welding section 14 to section 12.
[00114] [00114] The new load section 14 is mounted on section 12, receiving the skirt of the mounting section, which forms the peripheral edge described above. The skirt 44 that forms the peripheral edge formation 46 in section 12 is positioned so that it circumferentially surrounds the complementary formation 20 in the loading section 14, so that the surfaces of the two formations 20 and 46 are in contact. The two sections 12 and 14 are then welded together and the bucket 10 is ready to be replaced on the excavator 80 and to be reused. More specifically, the peripheral and peripheral edge formations 20 and 46 are welded to each other along their lengths, both inside and outside the bucket. The complementary contact surfaces are shown particularly clearly in Figures 1 and 3. During use, when it is pushed into the ground or dragged through the ground, the bucket is subjected to high forces, particularly high shear forces. This provides a fixture with sufficiently designed resistivity to perform its function.
[00115] [00115] A variation on bucket 10 shown in Figures 1 to 14 is shown in Figures 16 to 19. This bucket is similar to the bucket described above with reference to Figures 1 to 11 and therefore, unless otherwise stated, same reference numerals will be used to refer to the same components. Consequently, the following description will focus on the differences between this modality and the previous modality.
[00116] [00116] In this bucket, the assembly section is connected to the cargo transport section by means of fixing elements that are screws that pass through the assembly and cargo transport sections and fix the same joints.
[00117] [00117] In this bucket 10, the handling section 12 is attached to the cargo transport section 14 by means of fasteners 100 that are rivets that pass through the handling sections 12 and the cargo transport sections 14 and fix the same joints . The cross section in Figure 19 shows the rivets 100 that pass through the skirt 44 and the peripheral edge formation 20, in order to join the two sections.
[00118] [00118] An advantage of the bucket described above with reference to the drawings is that it allows a cargo transport section to be separated from a fixed bucket assembly section and to be placed with another new cargo transport section. This can be accomplished with minimal downtime.
[00119] [00119] Different buckets have different designs, particularly with regard to their cargo transport sections to perform different functions in different applications. For example, different designs of cargo transport sections are used to excavate soft soils when compared to excavation in rocky terrain.
[00120] [00120] Another advantage is that a certain cargo transport section can be separated from the bucket assembly section to which it is connected and be replaced by a different cargo transport section, of different design.
[00121] [00121] Another advantage is that the cargo transport section can be built with a lighter structure, knowing that it does not need to maintain the same lifespan as the bucket handling section. This helps to avoid the use of time-consuming and costly bucket linings to replace.
[00122] [00122] Another advantage of avoiding the use of bucket wear liners is that they can store energy and pose a safety risk when the linings are being removed.
[00123] [00123] The handling section can be designed for an extended and predetermined service life. Properly, the handling section can maintain structural integrity for a service life of up to about 3,000 hours or four to five years.
[00124] [00124] The complementary contact surfaces of the respective mounting formations provide a fixation with sufficiently designed resistivity to withstand the forces experienced in use.
[00125] [00125] An additional advantage is that the handling section is in the form of a top plate and the bucket walls are provided by the loading section. This allows the use of removable side plates.
[00126] [00126] Naturally, it will be understood that the above was provided only as an illustrative example of the invention and that all modifications and variations of the same, as would be evident to those skilled in the art, are considered to fall within the broad scope and scope of the invention, as presented in this document.
