Description

Technical Field

[0001] This utility model relates to the field of excavator bucket technology, specifically a wear-resistant block for a detachable excavator bucket. Background Technology

[0002] As the core operating device of construction machinery, the excavator bucket (hereinafter referred to as the bucket) must withstand complex loads for a long time during its service life. In the area where the bucket bottom directly contacts the working surface, deep wear grooves are easily formed due to the coupling effect of friction, impact, and corrosive media when excavating hard rock or high-strength materials, leading to a continuous decrease in structural strength. By installing wear-resistant blocks in vulnerable areas, local stress concentration can be effectively dispersed, and the cutting action of abrasives on the substrate can be blocked. This solution can improve the overall service life of the bucket.

[0003] However, existing wear-resistant block integration solutions have significant technical defects: traditional welded wear-resistant blocks use non-separable connections, making it difficult to implement targeted replacements when local wear exceeds the design threshold; while buckets using integral wear-resistant liners often exhibit excessive wear in the edge areas while the central area still has protective capabilities due to significant differences in mechanical distribution at the contact interface. This differential wear pattern forces the entire machine to be scrapped prematurely, increasing the resulting maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a detachable wear-resistant block for excavator buckets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable wear-resistant block for excavator buckets, comprising wear-resistant components, which are equidistantly arranged at the bottom of the bucket body, and both ends of the wear-resistant components are fixedly connected to the side wall of the bucket body through a fixing mechanism, and the fixing mechanism is also provided with a sealing component.

[0006] Preferably, in order to protect the bottom of the bucket and extend its service life, the wear-resistant component includes a first wear-resistant block, a second wear-resistant block, and a third wear-resistant block disposed at the bottom of the bucket body. The first wear-resistant block, the second wear-resistant block, and the third wear-resistant block are arranged sequentially from the front to the rear along the opening end of the bucket body.

[0007] Preferably, in order to set the wear-resistant blocks of corresponding thickness according to the severity of wear, so as to achieve better protection and facilitate subsequent replacement, the thickness of the first wear-resistant block, the second wear-resistant block, and the third wear-resistant block decreases sequentially.

[0008] Preferably, in order to facilitate the installation and fixing of the wear-resistant components and to facilitate subsequent disassembly operations, the fixing mechanism includes mounting blocks symmetrically arranged at both ends of the first wear-resistant block. Threaded holes are provided between the mounting blocks and the bucket body, and mounting screws are engaged in the threaded holes through threads.

[0009] Preferably, in order to facilitate installation and fixation, the mounting screws are hidden inside the mounting block, and the ends of the mounting screws are fixed with a retaining plate. The retaining plate has an internal hexagonal hole, and the mounting block has a retaining groove that matches the retaining plate. The retaining groove is connected to the threaded hole.

[0010] Preferably, for ease of installation and disassembly, the structures of the fixing mechanisms at both ends of the second and third wear-resistant blocks are the same as those of the fixing mechanisms at both ends of the first wear-resistant block.

[0011] Preferably, in order to seal and protect the internal hexagonal hole after installation and prevent external impurities from entering the interior without affecting subsequent disassembly operations, the sealing component includes a sealing groove on the side wall of the card plate that communicates with the internal hexagonal hole, and a sealing plate is provided in the sealing groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating wear-resistant components in the bucket assembly, with the thickness of these components decreasing from front to rear, the design adapts to actual wear patterns, enabling stepped utilization and extending overall lifespan. Thicker wear-resistant blocks can be installed in severely worn areas, while thinner blocks can be used in less worn areas, precisely matching actual working conditions. Furthermore, when the front end needs replacement due to wear, it can be disassembled and reassembled to the less worn rear end for protection, maximizing the use of wear-resistant blocks. Additionally, wear-resistant blocks in different locations can be disassembled and replaced individually, facilitating individual replacement and reducing maintenance costs.

[0014] The built-in fixing mechanism, in conjunction with the sealing component, allows for easy installation and fixation of the wear-resistant components. This facilitates protection of the bottom of the bucket during operation, extending its overall lifespan. It also allows for easy individual disassembly when disassembly or replacement is required. The sealing component can seal and protect the internal hexagonal hole during operation, preventing external impurities from entering the interior and thus not affecting subsequent disassembly operations.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a detachable wear-resistant block for an excavator bucket, comprising a wear-resistant component installed at the bottom of the bucket body 11. The wear-resistant component includes a first wear-resistant block 12, a second wear-resistant block 13, and a third wear-resistant block 14 equidistantly arranged at the bottom of the bucket body 11. The first wear-resistant block 12, the second wear-resistant block 13, and the third wear-resistant block 14 are sequentially arranged from the front to the rear along the opening end of the bucket body 11. Figure 1 As shown, the thickness of the first wear-resistant block 12, the second wear-resistant block 13, and the third wear-resistant block 14 decreases sequentially, with the first wear-resistant block 12 (closest to the bucket teeth) being the thickest and the third wear-resistant block 14 being the thinnest. When the excavator is in operation, the bottom of the bucket body 11 near the bucket teeth is frequently in contact with the ground or materials, while the rear end has relatively less contact. Therefore, the thickness gradually decreases from front to back. When the first wear-resistant block 12 wears down and needs to be replaced after a period of use, it can be installed in the rear as needed, becoming either the second wear-resistant block 13 or the third wear-resistant block 14. This maximizes the use of materials, extends service life, and avoids waste. The number of wear-resistant components at the bottom of the bucket body 11 can be set as needed, preferably three sets, but two, four, or five sets are also possible, with the thickness gradually decreasing from front to back.

[0022] Please see Figures 1-4To facilitate installation and fixation, as well as subsequent maintenance or replacement disassembly, the two ends of the wear-resistant components are fixedly connected to the side wall of the bucket body 11 via fixing mechanisms. The fixing mechanisms at both ends of the first wear-resistant block 12, the second wear-resistant block 13, and the third wear-resistant block 14 have identical structures. The following describes the fixing mechanism at both ends of the first wear-resistant block 12. The fixing mechanism includes symmetrically arranged (welded or integrally formed) mounting blocks 21 at both ends of the first wear-resistant block 12. Threaded holes 22 are provided between the mounting blocks 21 and the bucket body 11. Mounting screws 23 are threaded into the threaded holes 22. The ends of the mounting screws 23 are fixed (welded or integrally formed) with retaining plates 25. The retaining plates 25 have internal hexagonal holes 26 for easy... The mounting screw 23 is installed and removed. The mounting block 21 has a slot 24 that matches the card plate 25, which can hide the card plate 25 and prevent it from being exposed to the outside. The slot 24 is connected to the threaded hole 22. The sealing component includes a sealing groove 31 on the side wall of the card plate 25 that is connected to the internal hexagonal hole 26. The sealing groove 31 has a sealing plate 32, which can seal the internal hexagonal hole 26 after installation to prevent impurities from entering the interior and not affect the subsequent disassembly operation. The sealing plate 32 and the sealing groove 31 can be connected by snap-fit. The sealing plate 32 can have a notch (not shown in the figure) to facilitate the removal of the sealing plate 32 during subsequent disassembly, so as to facilitate the disassembly of the mounting screw 23 by matching the internal hexagonal hole 26.

[0023] Working principle: When using this utility model, when installing the first wear-resistant block 12, first place the first wear-resistant block 12 at the bottom of the bucket body 11, adjust the position of the first wear-resistant block 12 and the mounting block 21 so that the threaded hole 22 on the mounting block 21 coincides with the threaded hole 22 on the bucket body 11, and use an Allen wrench (manual or power tool) and the Allen hole 26 to install the mounting screw 23, thereby completing the fixation of the mounting block 21 to the bucket body 11, and thus completing the first wear-resistant block installation. After assembling the grinding block 12, the sealing plate 32 is inserted into the sealing groove 31 to seal and protect the internal hexagonal hole 26 without affecting its use. The above operation can be repeated to install the second wear-resistant block 13 and the third wear-resistant block 14 in sequence. When disassembly is required after a period of use, the sealing plate 32 can be removed from the sealing groove 31 first, and then the mounting screw 23 can be unscrewed to remove the installation fixation. The first wear-resistant block 12, the second wear-resistant block 13, or the third wear-resistant block 14 can be replaced, which is relatively convenient.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
