Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, specifically to a bucket and engineering machinery. Background Technology

[0002] Currently, buckets consist of a base plate and a wear-resistant plate, with the wear-resistant plate located at the bottom of the base plate to reduce wear. In related technologies, the wear-resistant plate is connected and fixed to the base plate by fasteners, the ends of which protrude from the surface of the base plate. On the one hand, during the bucket's cutting process, the protruding portion of the fastener creates significant resistance, affecting the bucket's working efficiency; on the other hand, during the cutting process, the protruding portion of the fastener is directly impacted by the material, bearing considerable shear force, thus affecting the fastener's service life. Utility Model Content

[0003] To address the aforementioned technical problems, embodiments of this application provide a bucket and engineering machinery that can improve the working efficiency of the bucket and extend the service life of fasteners.

[0004] Firstly, a bucket is provided, comprising:

[0005] Fighting body;

[0006] A bottom plate is connected to the bucket body, and the bottom plate is provided with a first assembly hole;

[0007] A wear-resistant plate is provided on the side of the bottom plate away from the bucket body, and the wear-resistant plate is provided with a second mounting hole;

[0008] Fasteners are fitted into the first mounting hole and the second mounting hole; wherein the opposite ends of the fasteners do not protrude from the surface of the base plate and the surface of the wear-resistant plate, respectively.

[0009] According to a first aspect of this application, the first mounting hole includes one of a threaded hole and a smooth hole; the second mounting hole includes the other of the threaded hole and the smooth hole.

[0010] The fastener passes through the light hole and engages with the threaded hole.

[0011] According to a first aspect of this application, the first mounting hole and / or the second mounting hole are countersunk holes.

[0012] According to a first aspect of this application, the base plate is provided with one of a wedge-shaped groove and a wedge-shaped block on the side near the wear-resistant plate;

[0013] The wear-resistant plate is provided with the other of the wedge-shaped groove and the wedge-shaped block on the side near the base plate;

[0014] The wedge groove engages with the wedge block to restrict the wear-resistant plate from sliding relative to the base plate in a predetermined direction.

[0015] According to a first aspect of this application, the wedge block includes an inclined wall, the inclined wall having an angle of N relative to the preset direction, wherein N satisfies: 0°<N≤15°.

[0016] According to a first aspect of this application, the base plate is provided with a first keyway on the side near the wear-resistant plate, and the wear-resistant plate is provided with a second keyway on the side near the base plate;

[0017] The bucket also includes:

[0018] The connecting key is embedded in the first keyway and the second keyway.

[0019] According to a first aspect of this application, the base plate is provided with one of a protrusion and a groove on the side near the wear-resistant plate;

[0020] The wear-resistant plate has one of the protrusions and the groove on the side near the base plate;

[0021] The protrusion engages with the groove.

[0022] According to a first aspect of this application, one end of the base plate and one end of the wear-resistant plate form a stepped surface;

[0023] The bucket also includes:

[0024] A limiting block is provided on the stepped surface, and the limiting block connects the base plate and the wear-resistant plate.

[0025] According to a first aspect of this application, the wear-resistant plate includes a plurality of separable wear-resistant blocks, each wear-resistant block being provided with an assembly groove, the plurality of wear-resistant blocks being spliced ​​together, and the assembly grooves of two adjacent wear-resistant blocks being spliced ​​together to form the second assembly hole.

[0026] Secondly, an engineering machinery is also provided, including:

[0027] Organism;

[0028] The bucket, as described in the previous embodiment, is connected to the machine body.

[0029] The bucket and construction machinery provided in this application embodiment fix the wear-resistant plate and the base plate relative to each other through fasteners engaging with the first and second mounting holes. The fasteners are positioned so that their opposite ends do not protrude from the surfaces of the base plate and the wear-resistant plate, respectively; that is, the fasteners are completely located inside the base plate and the wear-resistant plate. Therefore, during the bucket's cutting process, material is less likely to come into contact with the fasteners. This reduces the significant resistance caused by the fasteners during cutting, improving the bucket's working efficiency. Furthermore, it reduces the material impact on the fasteners, thereby reducing the shear force on the fasteners and extending their service life. Attached Figure Description

Detailed Implementation

[0043] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0044] Figure 1 This is a schematic diagram of the structure of a bucket provided for an exemplary embodiment of this application. Figure 2 for Figure 1 An enlarged view of point A in the middle. (See diagram below.) Figure 1 and Figure 2 As shown, the bucket 100 provided in this embodiment may include a bucket body 110 and a bottom plate 120, with the bottom plate 120 connected to the bucket body 110. In practical applications, the bottom plate 120 is generally located at the bottom of the bucket body 110 (see reference). Figure 1 (The placement state of the middle bucket 100) During the shoveling process of the bucket body 110, the bottom plate 120 can be used to carry materials.

[0045] like Figure 1 and Figure 2 As shown, the bucket 100 may also include a wear-resistant plate 130, which is disposed on the side of the bottom plate 120 away from the bucket body 110. During the operation of the bucket 100, the wear-resistant plate 130 can reduce the frequent contact of the bottom plate 120 with hard materials such as sand, gravel, ore, and concrete, reduce the wear of the bottom plate 120, and extend the service life of the bottom plate 120.

[0046] like Figure 1 and Figure 2 As shown, the base plate 120 is provided with a first mounting hole 121, and the wear-resistant plate 130 is provided with a second mounting hole 131. The bucket 100 may also include a fastener 140, which is fitted into the first mounting hole 121 and the second mounting hole 131, so that the fastener 140 can fix the wear-resistant plate 130 to the base plate 120.

[0047] In one embodiment, the fastener 140 may include bolts, screws, studs, etc.

[0048] like Figure 1 and Figure 2 As shown, the two opposite ends of the fastener 140 do not protrude from the surface of the base plate 120 and the surface of the wear plate 130, respectively. That is, with the bucket 100 in... Figure 1 and Figure 2 In the indicated state, the top end of fastener 140 does not protrude from the top surface of base plate 120, and the bottom end of fastener 140 does not protrude from the bottom surface of wear-resistant plate 130. During the scooping process of bucket 100, since fastener 140 is completely located inside base plate 120 and wear-resistant plate 130, material is less likely to come into contact with fastener 140. This reduces the resistance caused by fastener 140 during scooping, improving the working efficiency of bucket 100; it also reduces the impact of material on fastener 140, thereby reducing the shear force on fastener 140 and extending its service life.

[0049] It should be noted that in related technologies, considering that the fastener 140 needs to withstand a large shearing force, a fastener 140 with a larger nominal diameter is usually selected. This increases the usage cost of the fastener 140 and the weight of the bucket 100, affecting the working efficiency of the bucket 100. However, in this embodiment, the fastener 140 is completely set inside the base plate 120 and the wear-resistant plate 130. The fastener 140 is subjected to less impact from the material, and the shearing force is also smaller. Therefore, selecting a fastener 140 with a smaller nominal diameter can meet the operational requirements, effectively reducing the usage cost of the fastener 140, reducing the weight of the bucket 100, and improving the working efficiency of the bucket 100.

[0050] Figure 3 This is a schematic diagram of the structure of a plurality of wear-resistant blocks provided for an exemplary embodiment of this application. For example... Figure 3 As shown, the wear-resistant plate 130 may include a plurality of separable wear-resistant blocks 132. Each wear-resistant block 132 is provided with an assembly groove 133. After the plurality of wear-resistant blocks 132 are spliced ​​together, the assembly grooves 133 of two adjacent wear-resistant blocks 132 can be spliced ​​together to form the aforementioned second assembly hole 131.

[0051] It should be understood that the wear plate 130 adopts a split structure (including multiple separable wear blocks 132), which can save the replacement cost of the wear plate 130. That is, when one of the wear blocks 132 is damaged, the damaged wear block 132 can be replaced separately without replacing the entire wear plate 130, which can effectively save the replacement cost of the wear plate 130.

[0052] In one embodiment, the multiple wear-resistant blocks 132 may be the same size or different sizes.

[0053] In one embodiment, the number of wear-resistant blocks 132 is three, and the three wear-resistant blocks 132 are arranged in a predetermined direction (reference). Figure 2 The wear-resistant blocks 132 are distributed along the X-axis direction. The middle wear-resistant block 132 needs to bear more weight of the material. That is, the middle wear-resistant block 132 needs to have greater structural strength. Therefore, the size of the middle wear-resistant block 132 is usually larger than the size of the wear-resistant blocks 132 at both ends.

[0054] In one embodiment, multiple wear-resistant blocks 132 can be spliced ​​together by staggering along the height direction of the wear-resistant plate 130. This can improve the sealing between two adjacent wear-resistant blocks 132 and reduce the amount of material filling the gap between two adjacent wear-resistant plates 130.

[0055] In one embodiment, the first mounting hole 121 may include a threaded hole, and the second mounting hole 131 may include a smooth hole. The fastener 140 passes through the smooth hole and engages with the threaded hole. Thus, compared to the case where both the first mounting hole 121 and the second mounting hole 131 are threaded holes, the combination of a smooth hole and a threaded hole structure facilitates the fastener 140 to pass through the smooth hole quickly, improving the assembly efficiency of the fastener 140.

[0056] Reference bucket 100 Figure 1 and Figure 2 In the placement shown, with the first mounting hole 121 being a threaded hole and the second mounting hole 131 being a smooth hole, the fastener 140 is positioned from bottom to top (see details). Figure 2 Assembly is performed in the Y1 direction, that is, the fastener 140 first passes through the light hole and then mates with the threaded hole.

[0057] In one embodiment, the first mounting hole 121 may include a through hole, and the second mounting hole 131 may include a threaded hole. The fastener 140 passes through the through hole and engages with the threaded hole. Thus, compared to the case where both the first mounting hole 121 and the second mounting hole 131 are threaded holes, the combination of a through hole and a threaded hole structure facilitates the fastener 140 to pass through the through hole quickly, improving the assembly efficiency of the fastener 140.

[0058] Figure 4 A schematic diagram of the structure of a bucket provided for another exemplary embodiment of this application. Figure 5 for Figure 4 Enlarged view of point B. (Refer to bucket 100) Figure 4 and Figure 5 In the placement shown, with the first mounting hole 121 being a smooth hole and the second mounting hole 131 being a threaded hole, the fastener 140 is positioned from top to bottom (see details). Figure 5Assembly is performed in the Y2 direction, that is, the fastener 140 first passes through the light hole and then mates with the threaded hole.

[0059] like Figure 2 As shown, in one embodiment, the second mounting hole 131 is a countersunk hole. The fastener 140 first passes through the second mounting hole 131 and then mates with the first mounting hole 121. The end of the fastener 140 is located in the countersunk hole. The countersunk hole can effectively protect the end of the fastener 140 and prevent the end of the fastener 140 from colliding with other objects.

[0060] like Figure 5 As shown, in one embodiment, the first mounting hole 121 is a countersunk hole. The fastener 140 first passes through the first mounting hole 121 and then mates with the second mounting hole 131. The end of the fastener 140 is located in the countersunk hole. The countersunk hole can effectively protect the end of the fastener 140 and prevent the end of the fastener 140 from colliding with other objects.

[0061] It should be noted that in practical applications, when the bucket 100 is performing shoveling operations, the wear-resistant plate 130 tends to move relative to the base plate 120 in a preset direction (see details). Figure 2 Sliding in the X-axis direction will, on the one hand, affect the assembly stability between the wear-resistant plate 130 and the base plate 120; on the other hand, it will subject the fastener 140 to a large shear force, which will easily damage the fastener 140 and shorten its service life.

[0062] Therefore, such as Figure 2 As shown, the base plate 120 has a wedge-shaped groove 160 on the side near the wear-resistant plate 130, and the wear-resistant plate 130 has a wedge-shaped block 150 on the side near the base plate 120. The wedge groove 160 and the wedge block 150 are engaged, which restricts the wear-resistant plate 130 relative to the base plate 120 along a predetermined direction (see details). Figure 2 Sliding along the X-axis can improve the assembly stability between the wear-resistant plate 130 and the base plate 120, and also reduce the shear force on the fastener 140, thus extending the service life of the fastener 140.

[0063] In one embodiment, a wedge block 150 is provided on the side of the base plate 120 near the wear-resistant plate 130, and a wedge groove 160 is provided on the side of the wear-resistant plate 130 near the base plate 120. The wedge groove 160 engages with the wedge block 150. This also restricts the wear-resistant plate 130 relative to the base plate 120 along a predetermined direction (see details). Figure 2 Slide along the X-axis (in the X-axis direction).

[0064] like Figure 3As shown, the wedge block 150 may include an inclined wall 151, and the angle between the inclined wall 151 and the preset direction is N. If the angle N is too large, the contact area between the inclined wall 151 and the inner wall of the wedge groove 160 will be too small, which may easily lead to local deformation of the inclined wall 151 and the inner wall of the wedge groove 160.

[0065] Therefore, in this embodiment, the included angle N is limited to the following range: 0° < N ≤ 15°. This effectively mitigates the aforementioned problems caused by an excessively large included angle N.

[0066] In one embodiment, the included angle N can be selected as 5°, 7°, 15°, etc.

[0067] Figure 6 A schematic diagram of the structure of a bucket provided for another exemplary embodiment of this application. Figure 7 for Figure 6 An enlarged view of point C in the middle. (See diagram below.) Figure 6 and Figure 7 As shown, the bottom plate 120 has a first keyway 170 on the side near the wear-resistant plate 130, and the wear-resistant plate 130 has a second keyway 180 on the side near the bottom plate 120. Correspondingly, the bucket 100 may also include a connecting key 190, which is embedded in the first keyway 170 and the second keyway 180. In this way, the connecting key 190 can limit the bottom plate 120 and the wear-resistant plate 130, and can restrict the wear-resistant plate 130 relative to the bottom plate 120 in a preset direction (see reference). Figure 7 The fastener 140 slides along the X-axis direction, which can improve the assembly stability between the wear-resistant plate 130 and the base plate 120, reduce the shear force on the fastener 140, and extend the service life of the fastener 140.

[0068] Figure 8 A schematic diagram of the structure of a bucket provided for another exemplary embodiment of this application. Figure 9 for Figure 8 An enlarged diagram of point D in the middle. (See diagram below.) Figure 8 and Figure 9 As shown, a protrusion 210 is provided on the side of the base plate 120 near the wear-resistant plate 130, and a groove 220 is provided on the side of the wear-resistant plate 130 near the base plate 120. The protrusion 210 engages with the groove 220. In this way, the protrusion 210 can limit the position of the base plate 120 and the wear-resistant plate 130, and can restrict the wear-resistant plate 130 relative to the base plate 120 in a predetermined direction (see reference). Figure 9 The fastener 140 slides along the X-axis direction, which can improve the assembly stability between the wear-resistant plate 130 and the base plate 120, reduce the shear force on the fastener 140, and extend the service life of the fastener 140.

[0069] In one embodiment, the base plate 120 is provided with a groove 220 on the side near the wear-resistant plate 130, and the wear-resistant plate 130 is provided with a protrusion 210 on the side near the base plate 120. The protrusion 210 is engaged with the groove 220, which can also achieve the aforementioned effect of restricting the wear-resistant plate 130 from sliding relative to the base plate 120 in a preset direction.

[0070] Figure 10 A schematic diagram of the structure of a bucket provided for another exemplary embodiment of this application. Figure 11 for Figure 10 An enlarged view of point E in the middle. (See diagram below.) Figure 10 and Figure 11 As shown, one end of the base plate 120 and one end of the wear-resistant plate 130 form a stepped surface 230; the bucket 100 may also include a limiting block 240, which is disposed on the stepped surface 230 and connects the base plate 120 and the wear-resistant plate 130. In this way, the limiting block 240 can further fix the base plate 120 and the wear-resistant plate 130, and can also restrict the wear-resistant plate 130 relative to the base plate 120 along a predetermined direction (see reference). Figure 11 The fastener 140 slides along the X-axis direction, which can improve the assembly stability between the wear-resistant plate 130 and the base plate 120, reduce the shear force on the fastener 140, and extend the service life of the fastener 140.

[0071] In one embodiment, the limiting block 240 can be fixed to the base plate 120 by welding, and the limiting block 240 can be fixed to the wear-resistant plate 130 by welding.

[0072] In one embodiment, both ends of the base plate 120 and both ends of the wear-resistant plate 130 may be provided with stepped surfaces 230, and limiting blocks 240 may be provided on both stepped surfaces 230.
