[0002] The bucket is an important component in construction machinery for realizing earthmoving operations. Known construction machinery (such as loaders) usually only installs one bucket, and the capacity of this kind of bucket is usually fixed and not suitable for working in multiple working conditions. If it is necessary to increase the capacity of the bucket, it is usually known to install or weld a sub-edge on the bucket, but this solution has limited effect, and it can only increase the bucket capacity by 0.1 - 0.2 m 3 , and the length of the bottom wall and the side wall of the modified bucket does not match, resulting in a lack of stop for the materials in the bucket, causing material spillage and low efficiency. Or, a new bucket can be purchased additionally and used to replace the original bucket to change the capacity. Obviously, this solution has a high cost. Summary of the Utility Model

[0022] Embodiments of the present utility model will be described below with reference to the accompanying drawings. In the following description, many specific details are set forth in order to enable those skilled in the art to more fully understand and implement the present utility model. However, it is obvious to those skilled in the art that some of these specific details may not be required for the implementation of the present utility model. In addition, it should be understood that the present utility model is not limited to the specific embodiments described. On the contrary, any combination of the features and elements described below can be considered for implementing the present utility model, regardless of whether they relate to different embodiments. Therefore, the aspects, features, embodiments, and advantages described below are for illustrative purposes only and should not be regarded as elements or limitations of the claims unless expressly recited in the claims.

[0023] The terms "comprising" and "having" as used hereinafter are intended to mean an open inclusion and mean that there may be additional elements / components in addition to the listed elements / components.

[0024] In the description of the present utility model, the "lateral direction" is used to represent the direction transverse to the traveling direction of a construction machine (such as an excavator), and this lateral direction can also be referred to as the left-right direction, which is relative to the traveling direction being called the front-back direction; the "vertical direction" is used to represent the direction perpendicular to the traveling direction and the lateral direction, and can also be referred to as the up-down direction. Thus, the vertical direction, the lateral direction, and the traveling direction are perpendicular to each other pairwise. In this article, terms such as "up", "down", "above", "below", "upper surface", "lower surface", etc. are relative to the ground on which the construction machine operates, where the orientation closer to the ground is "down", and vice versa is "up".

[0025] Figures 1 to 3 Fig. shows a bucket device according to an embodiment of the present utility model. As Figure 1 shown, the bucket device according to this embodiment may include a bucket assembly 1 and an expansion assembly 2.

[0026] Figure 1 Fig. shows the state of the bucket assembly 1 when it is installed on a construction machine and not in operation, where the direction facing the observer (i.e., the direction extending out of the drawing) is called "front", which is also the direction in which the construction machine usually moves forward, and the opposite direction (i.e., the direction entering the drawing) is called "rear".

[0027] See Figure 2 and Figure 3 , the bucket assembly 1 may include a bucket main body 11, a main cutting edge plate 12, and two side cutting edge plates 13. The bucket main body 11 may include a bottom wall 111, a curved wall 112, a top wall 113, and two side walls 114 that jointly define its loading space. The bottom wall 111 is in a straight plate shape and extends horizontally or slightly inclined downward along the front-back direction, so as to facilitate the entry of materials into the loading space of the bucket main body 11. The curved wall 112 is flush with the bottom wall 111 in the lateral direction and extends backward and upward from the rear end of the bottom wall 111. The top wall 113 is in a straight plate shape and extends forward and upward from the top end of the curved wall 112. The side walls 114 extend along the lateral end edges of the bottom wall 111, the curved wall 112, and the top wall 113, that is, are connected to the bottom wall 111, the curved wall 112, and the top wall 113 substantially along the vertical direction.

[0028] The main cutting edge plate 12 is in a straight plate shape and is connected to the bottom wall 111 of the bucket main body 11, and thus continues to extend horizontally or slightly downward along the front-back direction along the bottom wall 111, and may be made of a material with higher stiffness than the bucket main body 11. The two side cutting edge plates 13 are in a straight plate shape, the left side cutting edge plate 13 is connected to the left side wall 114 of the bucket main body 11, and the right side cutting edge plate 13 is connected to the right side wall 114 of the bucket main body 11.

[0029] The expansion component 2 may include a main edge extension plate 21 and two side edge extension plates 22 that extend together in a direction away from the bucket body 11 (i.e., towards the front of the bucket). The main edge extension plate 21 is connected to the main edge plate 12 and extends along the main edge plate 12 in the lateral direction (left - right direction) and extends forward as a continuation of the main edge plate 12 in the front - rear direction. The left - hand side edge extension plate 22 is connected to the left - hand side edge plate 13 and extends along the side edge plate 13 in the vertical direction (up - down direction) and extends forward as a continuation of the side edge plate 13 in the front - rear direction. The right - hand side edge extension plate 22 is connected to the right - hand side edge plate 13, is arranged in the same way as the left - hand side edge extension plate 22, and is connected to the right end of the main edge extension plate 21. Thus, expansion can be carried out from the bottom side and the left and right sides of the bucket body 11 through the main edge extension plate 21 and the two side edge extension plates 22.

[0030] Advantageously, the main edge extension plate 21 and the two side edge extension plates 22 can be fixedly connected together, for example, by welding at their corresponding ends (i.e., the left end of the main edge extension plate 21 and the bottom end of the left - hand side edge extension plate 22, and the right end of the main edge extension plate 21 and the bottom end of the right - hand side edge extension plate 22), or can be detachably connected together, for example, by an elastic clamp. The elastic clamp includes, for example, an L - shaped spring plate, which can be inserted into a hole in the side edge extension plate 22 at one end and into a hole in the main edge extension plate 21 and / or the auxiliary edge plate 23 (to be described in detail below) below it at the other end. The holes can be process holes that exist on these plates themselves (formed during the processing), especially the process holes at the outermost ends of each plate (i.e., the outermost bottom end of the side edge extension plate 22 and the outermost left and right ends of the main edge extension plate 21 and / or the auxiliary edge plate 23).

[0031] Optionally, the rear edge of the main edge extension plate 21 has a shape that fits with the front edge of the main edge plate 12, and the rear edge of each side edge extension plate 22 fits with the front edge of the corresponding side edge plate 13.

[0032] For example, as can be seen from Figures 1 - 2 the front edge of the main edge plate 12 has a ramp surface (i.e., its cutting edge surface) that extends along the entire lateral direction of the main edge plate 12 and slopes forward and downward, and the rear edge of the main edge extension plate 21 has a mating ramp surface that extends along the entire lateral direction of the main edge extension plate 21 and slopes downward and forward. In this way, the front edge of the main edge plate 12 and the rear edge of the main edge extension plate 21 can be fitted or snapped together through the ramp surface and the mating ramp surface.

[0033] Again, for example, as Figure 2As shown, the front edge of the side cutting blade plate 13 has a flat surface at the upper part and a convex part 131 protruding forward at the lower part, while the rear edge of the side cutting blade extension plate 22 has a flat surface at the upper part and a concave part 221 recessed forward at the lower part. Thus, when the front edge of the side cutting blade plate 13 is joined to the rear edge of the side cutting blade extension plate 22, the front flat surface of the side cutting blade plate 13 abuts against the rear flat surface of the side cutting blade extension plate 22, and the front convex part 131 of the side cutting blade plate 13 engages with the rear concave part 221 of the side cutting blade extension plate 22.

[0034] In addition, the shape of the front edge of the main cutting blade extension plate 21 can be the same as that of the front edge of the main cutting blade plate 12, and the shape of the front edge of each side cutting blade extension plate 22 can be the same as that of the front edge of the corresponding side cutting blade plate 13. Thus, the main cutting blade extension plate 21 and the side cutting blade extension plate 22 can replace the functions of the main cutting blade plate 12 and the side cutting blade plate 13 during earthwork operations.

[0035] Optionally, the expansion assembly 2 may further include a secondary cutting blade plate 23. The secondary cutting blade plate 23 is disposed below the main cutting blade plate 12 and the main cutting blade extension plate 21. The top surface of the rear half of the secondary cutting blade plate 23 is joined to the bottom surface of the main cutting blade plate 12 and is fixed via a plurality of fasteners 25 (such as bolts and nuts, etc.). The top surface of the front half of the secondary cutting blade plate 23 is joined to the bottom surface of the main cutting blade extension plate 21 and is also fixed via a plurality of fasteners 25. Thus, the stiffness of the extended cutting blade (including the main cutting blade plate 12 and the main cutting blade extension plate 22) can be increased. Moreover, the front section of the secondary cutting blade plate 23 may have an inclined surface adapted to allow materials to enter the loading space of the bucket body 11, and this inclined surface can be joined to the front inclined surface of the main cutting blade extension plate 21 to form an integral working inclined surface.

[0036] Reference Figure 2 shows that the expansion assembly 2 may further include a plurality of connecting plates 24. These connecting plates 24 are arranged at intervals on the left and right sides of the bucket assembly 1. Their rear halves are fastened to the side cutting blade plate 13 via fasteners 25, and their front halves are fastened to the side cutting blade extension plate 22 via fasteners 25. Thus, the connection between the side cutting blade extension plate 22 and the corresponding side cutting blade plate 13 can be maintained and made flush or coplanar. Here, preferably, the plurality of connecting plates 24 can be arranged at intervals corresponding to the process holes existing on the side cutting blade plate 13 and the side cutting blade extension plate 22 itself, so that the fasteners 25 can pass through these process holes for fastening without having to drill new holes in the side cutting blade plate 13 or the side cutting blade extension plate 22.

[0037] Optionally, in order to improve the loading capacity of the bucket assembly 1 during the transportation of loaded materials, the expansion assembly 2 may further include two top extension plates 26 and two side extension plates 27, as Figure 1 and Figure 2 shown.

[0038] Specifically, the left top extension plate 26 is disposed at the end of the top wall 113 of the bucket body 11 that connects to the left side wall 114 and extends away from the bucket body 11. The left side extension plate 27 is disposed at the end of the left side wall 114 that connects to the top wall 113, and the upper end portion of the left side extension plate 27 is joined to the left top extension plate 26, thereby forming a generally "L"-shaped structure. The lower end portion of the left side extension plate 27 is fixed to the end portions of the left side blade plate 13 and the side blade extension plate 22. The right top extension plate 26 and side extension plate 27 can have similar and generally symmetrical structures to the left top extension plate 26 and side extension plate 27, and therefore will not be described in detail.

[0039] In the above embodiment, each side extension plate 27 can be advantageously constructed to partially overlap with the corresponding side blade plate 13 and side blade extension plate 22, so as to facilitate fixing the side extension plate 27 to the side blade plate 13 and side blade extension plate 22 through the connecting plate 24 and fastener 25 described above.

[0040] like Figure 1 and Figure 2 As shown, the bucket assembly 1 may further include a material deflector plate 14 disposed in the middle portion of the top wall 113 of the bucket body 11. In this case, each top extension plate 26 may be configured to extend from a lateral end of the top wall 113 of the bucket body along a portion of the length of the top wall 113 until it partially overlaps with the material deflector plate 14, thereby allowing the two top extension plates 27 and the material deflector plate 14 to jointly expand the capacity of the bucket assembly. In other embodiments, if the bucket assembly 1 lacks a material deflector plate, the two top extension plates 27 may be integrally formed and extend along the entire lateral dimension of the top wall 113.

[0041] Optionally, the expansion assembly 2 may further include a plurality of elastic locks 28 arranged at intervals, such as Figure 2 As shown. Each elastic lock 28 may include, for example, an Ω-shaped or U-shaped spring piece and a fastener 29. The two ends of the spring piece partially overlap the top wall 113 and the top extension plate 27, respectively, and are fixed to the top wall 113 and the top extension plate 27 at the corresponding overlapping portions by the fastener 29. The elasticity of the spring piece maintains the connection between the top extension plate 27 and the top wall 113 and prevents them from being dislocated.

[0042] The present invention also provides a machine tool system including the bucket device, the machine tool system includes a connecting rod, a movable arm and the bucket device. Figure 3As shown, on the outer side of the bending wall 112 of the bucket main body 11, there is a connecting rod hinge point 115 located in the middle, and boom hinge points 116 symmetrically arranged on both sides of the connecting rod hinge point 115. The connecting rod hinge point 115 can be arranged at a position close to the top wall 113, and the boom hinge point 116 can be arranged at a position closer to the bottom wall 111 than the connecting rod hinge point 115. The connecting rod of the construction machinery is connected to the connecting rod hinge point 115, and its boom is connected to the boom hinge point 116. In another embodiment, only one boom hinge point 116 can also be provided.

[0043] The present utility model further provides a construction machinery including the above-mentioned bucket device or implement system.

[0044] Industrial applicability

[0045] The bucket of the present utility model can be particularly applied to earthwork machinery such as loaders and excavators, but can also be applicable to other construction machinery.

[0046] The volume of the bucket in the prior art is fixed. If more working scenarios need to be matched, buckets with more volumes need to be equipped, and the disassembly, installation, and replacement of the bucket greatly increase the workload when switching working scenarios.

[0047] Compared with the prior art, on the one hand, through the main edge extension plate 21 and the side edge extension plate 22 respectively arranged on the front sides of the main edge plate 12 of the bucket device and the two side edge plates 13 and connected together, the present utility model realizes the front side expansion of the bucket main body 11 of the bucket device 1, and at least increases the volume available for earthwork operations and material transportation of the bucket device. On the other hand, by arranging the top extension plate 26 and the side extension plate 27 at the top wall 113 and the side wall 114 of the bucket main body 11, the present utility model further increases the volume that the bucket device can use when carrying materials, enabling it to quickly adapt to different working conditions.

[0048] Moreover, by making the rear edge of the main edge extension plate 21 fit with the front edge of the main edge plate 12, and making the rear edge of the side edge extension plate 22 fit with the front edge of the side edge plate 13, the present utility model ensures the matching of the edge and angle parameters of the expansion assembly 2 with the main edge plate 12 and the side edge plate 13, which can not only ensure the installation portability but also be positioned through its edge shape with the main edge plate 12 and the side edge plate 13, thus advantageously realizing the serialized design that can be applied to a series of buckets (such as a series of buckets with the same horizontal size and vertical size).

[0049] Those skilled in the art can make various modifications and variations to the embodiments disclosed above without departing from the scope or spirit of the present utility model. Based on the practice of the present utility model disclosed in this specification, other embodiments of the present utility model will be apparent to those skilled in the art. This specification and the examples disclosed therein should be considered illustrative only, and the true scope of the present utility model is defined by the appended claims and their equivalents.
