Description

Technical Field

[0001] The utility model relates to the technical field of parts of engineering machinery, in particular to a bucket, a machine tool system comprising the bucket, and engineering machinery comprising the bucket or the machine tool system. Background Art

[0002] Wheel loaders and crawler loaders are a type of earthmoving machinery widely used in construction projects such as highways, railways, buildings, and mines. They are used to dig, move, and dump materials at various locations around the worksite. A loader typically includes a bucket connected to the distal end of a lifting mechanism, which may be a linkage and drive structure (e.g., a cylinder) configured to lift and tilt the bucket.

[0003] Conventional buckets may include a curved main body wall and two sidewalls, one at each transverse end of the curved main body wall. The sidewalls are typically flat and perpendicular to the curved main body wall. Consequently, when moving large solid materials (such as rocks), a large gap between the bucket's sidewalls and the curved main body wall becomes difficult for the material to reach, reducing the bucket's loading efficiency. Furthermore, when dumping highly viscous materials, material adhering to the vertical connection between the sidewalls and the curved main body wall is difficult to remove, thereby reducing the bucket's emptying efficiency. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above problems and / or other problems existing in the prior art.

[0005] To achieve the above objectives, one aspect of the present invention provides a bucket comprising a curved main body wall and two side walls disposed at opposite transverse ends of the curved main body wall. Each side wall includes a side panel connected to the curved main body wall in a vertical direction perpendicular to the transverse direction, thereby defining a loading space for the bucket. Each side panel forms an angle greater than 90° with the corresponding end of the curved main body wall, so that material entering the loading space can reach the connection between the side panel and the curved main body wall.

[0006] According to one embodiment of the present invention, each of the side walls further comprises a side blade plate, each side blade plate is connected to the free end of a side plate and has a shape matching that of the side plate.

[0007] According to one embodiment of the present invention, both the side plate and the side blade plate have an arc-shaped or arched profile.

[0008] According to one embodiment of the present invention, each of the side panels forms a first angle less than or equal to 135° with the corresponding end portion of the curved main body wall, and each of the side blade plates forms a second angle greater than or equal to the first angle and less than or equal to 180° with the connected side panel.

[0009] According to one embodiment of the present invention, the curved main body wall includes a straight bottom plate portion and a curved back plate portion.

[0010] According to one embodiment of the present invention, the bucket further includes two reinforcing angle plates respectively provided at the connection between the two side walls and the back plate portion.

[0011] According to another aspect of the present invention, a machine system is provided, which includes a connecting rod, a boom and a bucket as described above, wherein the connecting rod is connected to a connecting rod hinge point on the curved main body wall, and the boom is connected to a boom hinge point on the curved main body wall.

[0012] Another aspect of the present invention provides an engineering machine, which includes the bucket or implement system as described above.

[0013] The sidewalls of the bucket of the present invention form an angle greater than 90° with the curved main body wall, thereby forming a bucket with outward-inclined sidewalls. Thus, when loading larger volumes of solid material, the material can smoothly reach the junction of the sidewalls and the curved main body wall, thereby increasing the fullness of the bucket and expanding the internal volume of the bucket.

[0018] Embodiments of the present invention are described below with reference to the accompanying drawings. In the following description, many specific details are set forth so that those skilled in the art can more fully understand and implement the present invention. However, it will be apparent to those skilled in the art that the present invention may be implemented without some of these specific details. Furthermore, it should be understood that the present invention is not limited to the specific embodiments described. On the contrary, any combination of the features and elements described below may be considered to implement the present invention, regardless of whether they relate to different embodiments. Therefore, the following aspects, features, embodiments, and advantages are for illustrative purposes only and should not be considered as elements or limitations of the claims unless expressly set forth in the claims.

[0019] In the following description, terms such as "first," "second," and the like are used to describe elements of the present application. These terms are only used to distinguish between the elements and are not used to limit the nature, order, or number of the elements. The terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components may be present in addition to the listed elements / components.

[0020] In the description of the present invention, the term "lateral direction" is used to refer to a direction transverse to the direction of travel of the construction machinery (e.g., a loader). The lateral direction may also be referred to as the left-right direction, which is relative to the direction of travel being referred to as the front-back direction. The term "vertical direction" is used to refer to a direction perpendicular to the direction of travel and the lateral direction, which may also be referred to as the up-down direction. Thus, the vertical direction, the lateral direction, and the direction of travel are perpendicular to each other. In this article, the terms "up," "down," "above," "below," "above," and "below" are relative to the ground on which the construction machinery is operating, where the direction closer to the ground is "down," and the opposite is "up."

[0021] Figure 1-3 FIG. 2 shows a bucket according to an embodiment of the present invention. Figure 1 As shown, the bucket according to this embodiment may include a curved main wall 1 and two side walls 2 respectively provided at both ends in the transverse direction of the curved main wall 1. The curved main wall 1 and the two side walls 2 may jointly define a loading space of the bucket.

[0022] refer to Figure 1 , which shows the bucket mounted on a construction machine and ready for excavation. The curved main body wall 1 of the bucket includes a bottom plate 11 and a back plate 12. The bottom plate 11 is straight and extends generally horizontally or slightly downwardly in the front-to-back direction to facilitate the entry of excavated material into the bucket's loading space. The back plate 12 is flush with the bottom plate 11 in the transverse direction and extends rearward and upward from the rear end of the bottom plate 11 in a curved manner.

[0023] Continue to refer Figure 1 Each side wall 2 may include a side plate 21, which is connected to the curved main body wall 1 along the transverse end edge of the curved main body wall 1, that is, substantially along the vertical direction. According to the present invention, in particular, Figure 2 As can be seen, the side panel 21 connected to the left side of the curved main wall 1 protrudes to the left beyond the left end edge of the curved main wall 1, while the side panel 21 connected to the right side of the curved main wall 1 protrudes to the right beyond the right end edge of the curved main wall 1. Thus, both side panels 21 and the curved main wall 1 form an angle greater than 90° at their connection (i.e., at the corresponding end edges of the curved main wall 1). This outwardly flared sidewall 2 configuration of the bucket allows larger volumes of material to easily slide down to the connection between the curved main wall 1 and the side panels 21, i.e., the bottom corner of the bucket, guided by the side panels 21 or the curved main wall 1 (particularly its bottom plate 11).

[0024] Figure 1-3 The peripheral portion of the side panel 21 shown in the figure that is in contact with and fixed to the curved main body wall 1 is called the fixed end of the side panel 21, and the peripheral portion of the side panel 21 that is not in contact with or connected to the curved main body wall 1 is called the free end of the side panel 21.

[0025] Optionally, each side wall 2 may further include a side blade plate 22 connected to the free end of the side plate 21. The side blade plate 22 may be made of a wear-resistant material and have an overall shape that matches the shape of the side plate 21. Figure 1 and Figure 3 As shown, both ends of the side blade plate 22 in the vertical direction are connected to the curved main body wall 1 and also form an angle greater than 90° with the curved main body wall 1. Specifically, the upper end of the side blade plate 22 is connected to the back plate portion 12 of the curved main body wall 1, and the lower end of the side blade plate 22 is connected to the bottom plate portion 11 of the curved main body wall 1, in particular, to the bottom blade plate 13 connected to the front edge of the bottom plate portion 11. Here, the bottom blade plate 13 can be made of a material with relatively high hardness or wear resistance.

[0026] Particularly preferably, the side panels 21 and the side blades 22 each have an arcuate (especially circular) or arched profile. In other words, the side panels 21 and the side blades 22 are each formed from an arcuate or arched plate. Specifically, when viewed from the direction facing the bucket's loading space, the middle portions of the side panels 21 and the side blades 22 arch outward (i.e., away from the loading space) relative to their end portions connected to the curved main body wall 1, and in particular, arch in a curved or arched shape. This gives the entire bucket a barrel-like shape.

[0027] Furthermore, the angle formed between each side panel 21 and the curved main wall 1 (especially the back panel 12) at the connection point, that is, at the corresponding lateral end of the curved main wall 1 (that is, the angle formed by the tangent of the side panel 21 passing through the connection point and the straight line of the curved main wall 1 in the lateral direction passing through the connection point) is defined as a "first angle". In addition to being greater than 90° as described above, the first angle is preferably less than or equal to 135°, for example, 120°. The angle formed between each side blade plate 22 connected to the free end of each side panel 21 and the corresponding side panel 21 (that is, the angle formed by the tangent of the side panel 21 passing through the connection point and the tangent of the side blade plate 22 passing through the connection point) is defined as a "second angle". The second angle is greater than or equal to the first angle and less than or equal to 180°. In this way, the side blade plates 22 and the side panels 21 can extend in the same direction, ensuring that materials will not slip off the edge of the side blade plates 22 during the loading operation of the bucket.

[0028] Optionally, the bucket may also include two reinforcing angle plates. Each reinforcing angle plate may include a first portion and a second portion, wherein the first portion is affixed to the side plate 21 or the side blade plate 22 of the side wall 2, or to both the side plate 21 and the side blade plate 22, in a certain fixing method (e.g., welding, bolting, etc.), and the second portion is affixed to the back plate portion 11 of the curved main body wall 1 in a similar fixing method. Thus, by providing the reinforcing angle plate at the connection between the side wall 2 and the curved main body wall 1, the connection strength between the curved main body wall 1 and the side wall 2 is advantageously increased.

[0029] The utility model also provides a machine system including a connecting rod, a movable arm and the above bucket. Figure 2 and Figure 3 The back plate portion 12 of the curved main body wall 1 is symmetrically provided with a pair of boom hinge points 121. The pair of boom hinge points 121 can be located near the bottom plate portion 11. The engineering machinery's actuator, such as the boom, can be hinged to the bucket at the boom hinge points 121. A connecting rod hinge point 122 is also provided on the back plate portion 12 between the pair of boom hinge points 121. The connecting rod hinge point 122 can be located further away from the bottom plate portion 11 than the boom hinge point 121. The engineering machinery's actuator, such as the connecting rod, can be hinged to the bucket at the connecting rod hinge point 122. In another embodiment, only one boom hinge point 121 can be provided.

[0030] The utility model also provides an engineering machine comprising the bucket or implement system.

[0031] Industrial Applicability

[0032] Although the present invention is described above by taking a loader as an example, the bucket according to the present invention can also be applied to other engineering machines such as an excavator.

[0033] In the bucket of the prior art, the side walls are usually substantially perpendicular to the curved main wall. Therefore, larger solid materials entering such a bucket tend to abut against the side walls and the curved main wall and be suspended between them, resulting in a large gap at the connection between the side walls and the curved main wall. Moreover, when unloading the materials in the bucket, the vertical side walls also make it difficult to provide good flow guidance for the fluid materials with high viscosity.

[0034] Compared to the prior art, the present invention forms a bucket with outwardly sloping sidewalls and a particularly barrel-shaped shape by connecting the side panels 21 and side blades 22, which constitute the sidewalls 2 and have a particularly curved profile, to the curved main wall 1 at an angle greater than 90°. When loading larger volumes of solid material, the material easily flows along the side panels 21 and the curved main wall 1 to or near the junction of the sidewalls 2 and the curved main wall 1, that is, to the bottom corners that are difficult to access in conventional buckets. This increases the bucket's material loadability and expands the bucket's internal volume.

[0035] In addition, the second angle between each side plate 21 and the corresponding side blade 22 is greater than or equal to the first angle formed with the corresponding end of the curved main wall 1. This helps ensure that materials can first enter the loading space under the guidance of the side blade 22 and reach the position of the side plate 21, and then reach the bottom of the loading space under the guidance of the side plate 21. This ensures that both solid and highly viscous liquid materials have better fluidity in the loading space, thereby improving the loading and unloading efficiency of the bucket.

[0036] Moreover, designing the second angle to be less than or equal to 180° can make the side blade 22 and the side plate 21 on the same guide line, preventing the side blade 22 from opening at a too large angle and causing material to leak from the side blade 22.

[0037] It will be apparent to those skilled in the art that various modifications and variations may be made to the embodiments disclosed above without departing from the scope or spirit of the present invention. Other embodiments of the present invention will be apparent to those skilled in the art from the practice of the present invention disclosed herein. This specification and the examples disclosed herein should be considered as illustrative only, and the true scope of the present invention is indicated by the appended claims and their equivalents.
