Description

Technical Field

[0001] The utility model belongs to the technical field of logistics equipment and relates to a material rack, in particular to a material rack suitable for storing buckets. Background Art

[0002] A bucket is a bucket-shaped component used to dig loose materials such as soil, sand, gravel and construction waste. It is often installed on an excavator and used as a bucket.

[0003] After being manufactured at the manufacturer, buckets need to be shipped to an assembly plant and assembled with an excavator before they can be sold or used. To prevent bumps and damage to the paint during transportation, which could affect sales, the existing solution is for the manufacturer to package the finished buckets, then bundle them onto a transport vehicle for transport to the assembly plant. Assemblers then remove the buckets from the packaging and assemble them with the excavator.

[0004] This traditional bucket turnover and transportation method is time-consuming and labor-intensive, both in the packaging and retrieval stages. It not only affects the bucket's turnover and transportation efficiency, but also makes it difficult to reuse the removed packaging, resulting in a waste of resources. Summary of the Invention

[0005] Aiming at the problem that the existing packaging and fixing method of buckets is time-consuming, labor-intensive and inefficient during turnover and transportation, the utility model proposes a bucket material rack, which not only prevents the buckets from being bumped during turnover and transportation, but also makes the fixing and taking operations simple and quick, saves time and is highly efficient.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A bucket frame, comprising:

[0008] A main body, comprising a bottom bracket, a top bracket, and a support body installed between the bottom bracket and the top bracket;

[0009] The U-shaped plug-in parts include two parts, which are respectively placed on opposite sides of the top bracket, and the opening sides of the two U-shaped plug-in parts are arranged to face each other;

[0010] A perforated shaft, which passes through the bucket ear sleeve on the bucket when in use, and has its two ends respectively inserted into the two U-shaped insertion parts and supported on the top bracket;

[0011] The U-shaped locking part includes two parts, which are movably assembled with the two U-shaped plug-in parts respectively; the U-shaped locking part is locked when it is flipped to a position orthogonal to the U-shaped plug-in part, and forms a semi-closed area with the U-shaped plug-in part, leaving only the open side of the U-shaped plug-in part open, so as to block the two ends of the perforated shaft.

[0012] In some embodiments of the present application, in order to limit the flipping path and angle of the U-shaped locking portion, a guide column can be installed on the U-shaped plug-in portion, and a special-shaped guide hole can be opened on the U-shaped locking portion. The guide column is installed in the special-shaped guide hole. When the U-shaped locking portion flips relative to the U-shaped plug-in portion, the guide column is restricted to move only along the special-shaped guide hole, thereby achieving the purpose of limiting the opening position and locking position of the U-shaped locking portion.

[0013] In some embodiments of the present application, a first elongated hole and a second elongated hole can be provided in the special-shaped guide hole; wherein, the first elongated hole includes a first end portion and a second end portion positioned opposite to each other, and the first end portion of the first elongated hole can be used as the starting point for movement of the guide column to limit the maximum opening position of the U-shaped locking portion; the second elongated hole is arranged in parallel with the first elongated hole and is connected to the first elongated hole, and the connection position can be close to or located at the second end portion of the first elongated hole, so that the guide column can be rotated into the second elongated hole when it moves close to the second end portion of the first elongated hole; the second elongated hole is configured to have a terminal end that exceeds the second end portion of the first elongated hole in its length direction, and the terminal end is configured as the moving end point of the guide column to limit the U-shaped locking portion to a predetermined locking position.

[0014] In some embodiments of the present application, the second elongated hole has a first end and a second end that are positioned opposite each other, and the second end of the second elongated hole is configured as the terminal end of the second elongated hole, that is, the moving end point of the guide post; the connection position between the second elongated hole and the first elongated hole is configured to be located at the first end of the second elongated hole or the middle part of the second elongated hole; the length of the first elongated hole is configured so that when the guide post moves from the first end of the first elongated hole to the second end, the U-shaped locking portion flips from the open position to above the U-shaped insertion portion; the length of the second elongated hole is configured so that when the guide post moves to the second end of the second elongated hole, the U-shaped locking portion locks with the U-shaped insertion portion, and when the guide post moves to the first end of the second elongated hole, the U-shaped locking portion disengages the locked position. By reasonably configuring the lengths of the first and second elongated holes, as well as the connection position between the first and second elongated holes, the U-shaped locking portion can be controlled to accurately flip and switch between its open position and locked position, thereby simplifying the operation difficulty.

[0015] In some embodiments of the present application, in order to reduce costs, the guide column can use a cylindrical pin with a pin cap that is commonly found on the market, and the diameter of the pin should be smaller than the width of the first elongated hole and the second elongated hole, and the diameter of the pin cap should be larger than the width of the first elongated hole and the second elongated hole, so that the pin can be restricted in the special-shaped guide hole by the pin cap.

[0016] In some embodiments of the present application, when a cylindrical pin is used for the guide post, the first end of the first elongated hole and the terminal end of the second elongated hole can be configured to be semicircular, with the radius of the semicircular arc being configured to match the radius of the pin. This allows the pin to tightly mate with the end of the elongated hole when it is at the starting and ending points of movement, thereby improving the stability of the U-shaped locking portion in both the open and locked positions.

[0017] In some embodiments of the present application, the U-shaped insertion portion includes a first side plate and a second side plate positioned opposite to each other, and a connecting plate connected between the first side plate and the second side plate. The first side plate, the second side plate and the connecting plate are arranged perpendicular to the top bracket, so that the U-shaped insertion portion is open only on the top and the inside. The inside is open for the insertion of the perforating shaft, and the top opening can be blocked by the U-shaped locking portion, thereby forming a semi-closed area that can limit the movement of the perforating shaft, thereby achieving the purpose of locking the perforating shaft on the top bracket.

[0018] At the same time, the U-shaped locking part is configured to include a first side plate and a second side plate positioned opposite to each other, and a connecting plate connected between the first side plate and the second side plate, and the first side plate and the second side plate of the U-shaped locking part are respectively placed on the outsides of the first side plate and the second side plate of the U-shaped plug-in part, and a special-shaped guide hole is respectively opened on the first side plate and the second side plate of the U-shaped locking part, and a guide column is respectively installed on the outside of the first side plate and the second side plate of the U-shaped plug-in part, and the two guide columns are respectively installed in the two special-shaped guide holes, thereby realizing the rotational assembly of the U-shaped locking part on the U-shaped plug-in part.

[0019] In some embodiments of the present application, in order to enable the U-shaped locking portion to flip over to the top of the U-shaped insertion portion and reach the locking position after falling a certain distance, the length direction of the first elongated hole and the second elongated hole in the special-shaped guide hole can be configured to be parallel to the length direction of the first side plate and the second side plate of the U-shaped locking portion; and the second elongated hole can be configured to be away from the opening side of the U-shaped insertion portion relative to the first elongated hole; at the same time, the first end portion of the first elongated hole is configured to be adjacent to the opening side of the U-shaped locking portion, and the terminal end of the second elongated hole is adjacent to the connecting plate of the U-shaped locking portion.

[0020] In some embodiments of the present application, in order to prevent the U-shaped locking portion from jumping out of the locked position due to vibration during turnover transportation, the U-shaped locking portion can be made of metal material, and a magnet can be installed on the top surface of the U-shaped plug-in portion. When the U-shaped locking portion is rotated to a position orthogonal to the U-shaped plug-in portion, the U-shaped locking portion is attracted by the magnet to ensure that the U-shaped locking portion can be stably maintained in the locked position during turnover transportation.

[0021] In some embodiments of the present application, in order to improve the stability of the bucket when assembled in the material frame, a quadrilateral frame, a tooth seat plate support beam, a guide frame and a stop plate can be arranged in the bottom bracket; wherein, the quadrilateral frame includes a front bracket, a rear bracket, a left bracket and a right bracket, and the left bracket and the right bracket are opposite to the layout positions of the two U-shaped plug-in parts on the top bracket; the tooth seat plate support beam is installed between the left bracket and the right bracket to support the tooth seat plate of the bucket; the guide frame can be installed in the middle position of the inner side of the front bracket to guide the middle bucket teeth of the bucket to be inserted therein; the stop plate can be vertically installed on the front bracket for the bucket teeth to rest against it to limit the bucket to the area surrounded by the material frame body.

[0022] In some embodiments of the present application, the support body of the main body can be designed as a height-adjustable column, and the height of the column can be adjusted according to the height of the bucket, so that the material rack of the present application can adapt to buckets of different sizes.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are mainly reflected in:

[0024] 1. The utility model designs a special material rack for the bucket, which is used in the turnover and transportation process of the bucket.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0046] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0047] Material racks, also known as shelves, are logistics equipment primarily used for the storage and mechanized turnover of larger or heavier items, but are rarely used to store buckets. This leads to the current practice of transporting buckets using traditional methods such as wrapping, bundling, and screw fastening, which is time-consuming, labor-intensive, and inconvenient to access.

[0048] In order to make the rack suitable for storing buckets and realize the mechanized turnover and transportation of buckets, this embodiment designs a bucket rack, combined with Figure 1 、 Figure 9 As shown, it mainly includes a main body 100, a U-shaped inserting portion 200, a U-shaped locking portion 300, a perforated shaft 400 and other components.

[0049] The main body 100 serves as the overall bearing unit of the entire bucket frame, and mainly includes components such as a bottom bracket 110 , a top bracket 120 , and a support body 130 .

[0050] In some embodiments, in order to reduce the overall weight of the bucket frame and facilitate handling and transfer, the main body 100 can be designed as a frame structure to form a storage space around the bucket.

[0051] Specifically, if Figure 1 、 Figure 2 As shown, the bottom bracket 110 in the main body 100 can be designed as a quadrilateral frame structure, including a front bracket 111, a rear bracket 112, a left bracket 113 and a right bracket 114, which are located at the bottom layer of the entire material rack, connected to the support body 130, and connected to the top bracket 120 through the support body 130.

[0052] In some embodiments, the front bracket 111 , the rear bracket 112 , the left bracket 113 and the right bracket 114 can all be designed as upper and lower brackets, and supported between the upper and lower brackets by pillars 115 to increase the supporting strength of the bottom bracket 110 .

[0053] A tooth seat plate support beam 116 may be connected between the left bracket 113 and the right bracket 114 to support the tooth seat plate 550 of the bucket 500. Figure 1 、 Figure 8 、 Figure 10 Considering that the tooth seat plate 550 of most buckets is slightly tilted relative to the bottom plate 520 of the bucket, the top surface of the tooth seat plate support beam 116 in the rack of this embodiment is designed to be an inclined surface with a lower front surface and a higher rear surface, so that the top surface of the tooth seat plate support beam 116 can better fit the bottom surface of the tooth seat plate 550 of the bucket to achieve stable support.

[0054] In order to guide the bucket to be quickly positioned when placed in the main body 100, a guide frame 117 may be installed on the bottom bracket 110 of the main body 100, such as Figure 2 The guide frame 117 can be installed in the middle position of the inner side of the front bracket 111 to guide the middle bucket tooth 560 of the bucket 500 to be inserted therein, thereby limiting the front end of the bucket.

[0055] In some embodiments, guide surfaces can be formed on the top surface and rear side surface of the guide frame 117, respectively. In this way, regardless of whether the bucket teeth 560 of the bucket 500 approach the front bracket 111 from above or behind the front bracket 111, they can be quickly inserted into the guide frame 117 under the guidance of different guide surfaces to simplify the positioning operation of the bucket teeth 560.

[0056] In order to prevent the bucket teeth 560 of the bucket 500 from extending out of the bottom bracket 110, a stopper plate 118 may be further installed on the front bracket 111. Figure 1 、 Figure 2 The stop plate 118 is configured to be vertically mounted on the top surface of the front bracket 111 so that the teeth 560 of the bucket 500 can rest against it. Figure 11 As shown, the bucket 500 is further restricted within the area surrounded by the rack body 100 .

[0057] The support body 130 is mounted on the bottom bracket 110, such as Figure 1 The support body 130 may be four upright posts, mounted at the four corners of the bottom bracket 110 and extending vertically upward perpendicular to the bottom bracket 110. The top bracket 120 is mounted on the support body 130 and positioned directly above the bottom bracket 110 to form a quadrilateral structure.

[0058] In some embodiments, the support body 130 may be designed as a height-adjustable column. By changing the height of the column, the overall height of the main body 100 may be adjusted to accommodate buckets of different heights.

[0059] The top support 120 of the main body 100 can also be designed as a quadrilateral frame structure, such as Figure 1 As shown, it includes a front bracket 121, a rear bracket 122, a left bracket 123, and a right bracket 124. Two opposite brackets are selected to install U-shaped inserting parts 200. For example, a U-shaped inserting part 200 can be installed on each of the left bracket 123 and the right bracket 124, so that the two ends of the perforating shaft 400 can be inserted therein, and then cooperate with the U-shaped locking part 300 to achieve the locking of the two ends of the perforating shaft 400. It should be noted that the installation direction of the perforating shaft 400 on the main body 100 should be parallel to the installation direction of the tooth seat plate support beam 116 to ensure that the bucket 500 can be properly assembled in the main body 100.

[0060] In this embodiment, the two U-shaped plug-in parts 200 can be placed horizontally and installed on the top surfaces of the left bracket 123 and the right bracket 124, and the U-shaped opening sides 240 are arranged facing each other, that is, the U-shaped opening sides 240 of the two U-shaped plug-in parts 200 are both facing the inner side of the main body 100.

[0061] Specifically, if Figure 4 As shown, a first side plate 210, a second side plate 220, and a connecting plate 230 can be respectively provided in the two U-shaped insertion portions 200. The first side plate 210 and the second side plate 220 are in a parallel and opposing positional relationship, and the connecting plate 230 is installed on the same side of the first side plate 210 and the second side plate 220. The connecting plate 230 spans between the first side plate 210 and the second side plate 220 to form a U-shape.

[0062] The first side plate 210, the second side plate 220 and the connecting plate 230 are mounted on the bracket in a direction perpendicular to the top surface of the bracket, such as Figure 6As shown, the first side plate 210 and the second side plate 220 are configured with the side not mounted with the connecting plate 230 facing the inside of the main body 100, forming an open side 240 of the U-shaped inserting portion 200. After the U-shaped inserting portion 200 is horizontally mounted on the top bracket 200, only the top surface and the inner side of the U-shaped inserting portion 200 are left open. The U-shaped locking portion 300 is used to block the top surface of the U-shaped inserting portion 200, forming a semi-enclosed area with only the open side 240 open. This allows the end of the perforated shaft 400 inserted into the U-shaped inserting portion 200 through the open side 240 to be locked in place.

[0063] In this embodiment, if Figure 3 As shown, the U-shaped locking portion 300 may include a first side plate 310, a second side plate 320, and a connecting plate 330. The first side plate 310 and the second side plate 320 are positioned parallel to each other, and the connecting plate 330 is mounted on the same side of the first side plate 310 and the second side plate 320. The connecting plate 330 spans between the first side plate 310 and the second side plate 320 to form a U-shape. Special-shaped guide holes 350 are respectively opened on the first side plate 310 and the second side plate 320, and guide columns 250 are respectively installed on the outer sides of the first side plate 210 and the second side plate 220 of the U-shaped plug-in part 200. Combined with the figure shown in Figure 4, the first side plate 310 and the second side plate 320 of the U-shaped locking part 300 are respectively placed on the outer sides of the first side plate 210 and the second side plate 220 of the U-shaped plug-in part 200, and the guide columns 250 are installed in the special-shaped guide holes 350, thereby realizing the movable assembly of the U-shaped locking part 300 on the U-shaped plug-in part 200.

[0064] When the U-shaped locking portion 300 is flipped relative to the U-shaped inserting portion 200, the guide post 250 moves in the special-shaped guide hole 350. When the guide post 250 moves to the starting position, the U-shaped locking portion 300 is in an open state relative to the U-shaped inserting portion 200, as shown in FIG. Figure 4 As shown, the top surface of the U-shaped inserting portion 200 is open at this time, so that the end of the perforating shaft 400 can be placed into the U-shaped inserting portion 200. When the guide column 250 moves to the end position, the U-shaped locking portion 300 is in a closed state relative to the U-shaped inserting portion 200, as shown in FIG. Figure 5 As shown, at this time, the connecting plate 330 of the U-shaped locking part 300 rotates to the top of the U-shaped insertion part 200, acting as a pressure plate to block the top surface of the U-shaped insertion part 200, so as to form a semi-enclosed area with only the open side 240 of the U-shaped insertion part 200 open, thereby sealing the end of the perforated shaft 400 and locking the perforated shaft 400 on the top bracket 120.

[0065] In order to limit the turning path and turning angle of the U-shaped locking portion 300 relative to the U-shaped inserting portion 200, the shape of the special-shaped guide hole 350 is specially designed in this embodiment, such as Figure 3As shown, it may include a first elongated hole 351 and a second elongated hole 352 that are connected to each other.

[0066] The length direction of the first elongated hole 351 is parallel to the length direction of the first side plate 310 or the second side plate 320 of the U-shaped locking portion 300 , and is closer to the opening side 240 of the U-shaped inserting portion 200 than the second elongated hole 352 .

[0067] The first elongated hole 351 has a first end portion 353 and a second end portion 354 in opposite positions in the length direction. Figure 3 The first end portion 353 is adjacent to the opening side 340 of the U-shaped locking portion 300 and can be used as the starting point for the movement of the guide column 250 to limit the maximum flip angle of the U-shaped locking portion 300 relative to the U-shaped insertion portion 200 when it is opened. Figure 4 The second end 354 of the first elongated hole 351 is located adjacent to the connecting plate 330 of the U-shaped locking portion 300. The length of the first elongated hole 351 can be configured so that when the guide post 250 moves from the first end 353 to the second end 354 of the first elongated hole 351, the U-shaped locking portion 300 rotates from the open position to directly above the U-shaped inserting portion 200. In other words, the length of the first elongated hole 351 limits the maximum tilting angle of the U-shaped locking portion 300 relative to the U-shaped inserting portion 200.

[0068] The first elongated hole 351 is connected to the second elongated hole 352, and the connection position can be close to or located at the second end 353 of the first elongated hole 351, so that the guide column 250 can be transferred into the second elongated hole 352 through the connecting section after moving from the first end 353 to the second end 354 of the first elongated hole 351.

[0069] The second elongated hole 352 is arranged in a longitudinal direction parallel to the length direction of the first side plate 310 or the second side plate 320 of the U-shaped locking portion 300 and is further away from the opening side 240 of the U-shaped inserting portion 200 than the first elongated hole 351 .

[0070] like Figure 3 As shown, the second elongated hole 351 has a first end 355 and a second end 356 positioned opposite each other along its length. The second end 356 serves as the terminal end, defining the end point of movement of the guide post 250. It is adjacent to the connecting plate 330 of the U-shaped locking portion 300 and extends beyond the second end 354 of the first elongated hole 351 along the length of the two elongated holes, closer to the connecting plate 330 of the U-shaped locking portion 300.

[0071] The second elongated hole 352 is connected to the first elongated hole 351 at the first end 355 of the second elongated hole 352 or at the middle of the second elongated hole 352, so that the guide post 250 can move upward to the second end 356 of the second elongated hole 352 after passing through the connecting section from the first elongated hole 351 to the second elongated hole 352, thereby causing the connecting plate 330 of the U-shaped locking portion 300 to press against the top surface of the U-shaped insertion portion 200 and lock it. Figure 5 Shown in closed state.

[0072] The length of the second elongated hole 352 is configured so that when the guide post 250 moves to the second end 356 of the second elongated hole 352, the U-shaped locking portion 300 reaches the locked position. When the guide post 250 moves to the first end 355 of the second elongated hole 352, the U-shaped locking portion 300 is released from the locked position. The guide post 250 then pivots through the connecting section into the first elongated hole 351 and moves toward the first end 353 of the first elongated hole 351, causing the U-shaped locking portion 300 to flip open.

[0073] To prevent the guide post 250 from disengaging from the irregular guide hole 350, in some embodiments, a cylindrical pin with a pin cap can be used as the guide post 250 and mounted on the first side plate 210 and the second side plate 220 of the U-shaped insertion portion 200. The pin is configured with a diameter smaller than the width of the first elongated hole 351 and the second elongated hole 352, and the pin cap is configured with a diameter larger than the width of the first elongated hole 351 and the second elongated hole 352. In this way, the pin cap can stop the pin in the irregular guide hole 350.

[0074] In order to enable the pin shaft to stably cooperate with the special-shaped guide hole 350 at the starting point and the end point of movement, the first end 353 of the first elongated hole 351 and the second end 356 of the second elongated hole 352 can be designed into a semicircular arc shape, and the radius of the semicircular arc is configured to match the radius of the pin shaft, so that the pin shaft can stably abut against the first end 353 of the first elongated hole 351 and the second end 356 of the second elongated hole 352 at the starting point and the end point of movement, thereby improving the stability of the U-shaped locking part 300 in the open position and the locked position.

[0075] Of course, in the case where the guide column 250 is a cylindrical pin shaft, the second end 354 of the first elongated hole 351 and / or the first end 355 of the second elongated hole 352 can also be designed to be semicircular, and the radius of the semicircular can be configured to match the radius of the pin shaft to improve the stability and tightness of the pin shaft when pressed at each end.

[0076] In order to prevent the U-shaped locking part 300 from jumping up due to vibration during turnover transportation, causing the guide column 250 to move down along the second long hole 352 and disengage from the locked position, resulting in the U-shaped locking part 300 accidentally opening, releasing the lock on the end of the perforating shaft 400, and then causing the perforating shaft 400 to disengage from the top bracket 120, causing the bucket 500 to fall from the material rack, this embodiment installs a magnet 260 on the top surface of the U-shaped insertion part 200, and uses metal material to make the U-shaped locking part 300, and uses the suction force of the magnet 260 to prevent the U-shaped locking part 300 from accidentally jumping up and keep it in the locked position.

[0077] For example, a groove may be provided on the top surface of the first side plate 210 and the second side plate 220 of the U-shaped insertion portion 200, such as Figure 7 As shown, a magnet 260 is then installed in each groove. When the connecting plate 330 of the U-shaped locking portion 300 is pressed against the top surfaces of the first side plate 210 and the second side plate 220 of the U-shaped insertion portion 200, the magnet 260 and the connecting plate 330 of the U-shaped locking portion 300 are attracted to each other, firmly locking the U-shaped locking portion 300 in a closed state, thereby preventing the perforated shaft 400 from falling off the top support leg 120 during the rack turnover and transportation process.

[0078] One of the U-shaped locking parts 300 is respectively assembled on the two U-shaped inserting parts 200 facing each other, so that the two ends of the perforated shaft 400 can be locked on the left bracket 123 and the right bracket 124 of the top bracket 120 .

[0079] In this embodiment, the perforating shaft 400 can be a hollow cylindrical shaft, such as Figure 9 As shown, the diameter of the perforating shaft 400 is configured to be smaller than the diameter of the through-hole 542 of the bucket ear sleeve 541 on the bucket 500, so that the perforating shaft 400 can smoothly pass through the bucket ear sleeve 541 and lift the rear portion of the bucket 500. Furthermore, the length of the perforating shaft 400 is configured to match the width of the top bracket 120 of the material rack body 100. For example, the length of the perforating shaft 400 is determined based on the distance between the left bracket 123 and the right bracket 124 of the top bracket 120, so that both ends of the perforating shaft 400 can be stably supported on the top surfaces of the left bracket 123 and the right bracket 124.

[0080] Industrial Applicability

[0081] The existing bucket 500 is generally formed into a bucket shape by a back plate 510, a bottom plate 520, and a wall plate 530. Figure 8As shown in the figure, the back plate 510 is located above the bucket, and is mounted on a bucket lug plate 540. Bucket lug plates 540 are provided with bucket lug sleeves 541. Bucket lug sleeves 541 have through-holes 542 for the shaft to pass through, which is used to mount the bucket 500 on the excavator. The bottom plate 520 is located at the bottom of the bucket, with wall panels 530 mounted vertically on both sides. A tooth base plate 550 is mounted at the front end of the bottom plate 520, and bucket teeth 560 are mounted on the tooth base plate 550 via tooth bases 561.

[0082] After the manufacturer has finished processing the bucket 500, the manufacturer first inserts the perforated shaft 400 into the bucket ear sleeve 541 of the bucket. Figure 9 Then, the bucket 500 is lifted and placed into the rack body 100 .

[0083] Adjust the position of the bucket 500 in the rack body 100, insert the middle bucket tooth 560 of the bucket 500 into the guide frame 117 of the rack; place the tooth seat plate 550 of the bucket 500 against the tooth seat plate support beam 116 of the rack; flip the two U-shaped locking parts 300 to the maximum open position to open the top surface openings of the two U-shaped insertion parts 200; insert the two ends of the perforated shaft 400 into the two U-shaped insertion parts 200 respectively, and support them on the top bracket 120 of the rack body 100, as shown in FIG. Figure 10 As shown; flip the two U-shaped locking parts 300 in the opposite direction, flip the connecting plate 330 of the U-shaped locking part 300 to the top of the U-shaped inserting part 200; move the U-shaped locking part 300 downward so that the connecting plate 330 of the U-shaped locking part 300 abuts against the top surface of the U-shaped inserting part 200, blocking the top surface opening of the U-shaped inserting part 200, and locking both ends of the perforated shaft 400 to the top bracket 120 of the rack body 100, as shown Figure 11 As shown, the bucket 500 is installed and fixed in the material rack.

[0084] Use mechanized transfer equipment such as cranes or trailers to move the racks as a whole to other sites or load them onto trucks for transport to assembly plants.

[0085] To remove the bucket 500 from the rack, first lift the two U-shaped locking parts 300 to release them from the locked position; then, flip the two U-shaped locking parts 300 to the open position, opening the top surface openings of the two U-shaped inserting parts 200; lift the perforated shaft 400, disengage the two ends of the perforated shaft 400 from the two U-shaped inserting parts 200, and remove the bucket 500 from the top of the rack body 100. After that, it can be assembled with the excavator.

[0086] When using the rack of this embodiment to store and retrieve the bucket 500, the perforating shaft 400 can be locked and unlocked by simply flipping the U-shaped locking part 300. The storage and retrieval operations are simple and fast, saving time and effort, and helping to improve the turnover and transportation efficiency of the bucket.
