Description

Technical Field

[0001] This utility model relates to a wear-resistant structure, and more particularly to a wear-resistant structure for excavators. Background Technology

[0002] Excavators are indispensable pieces of equipment in modern engineering construction and mineral resource extraction, and their buckets are the core components that directly participate in operations. The performance of the bucket directly affects the excavator's working efficiency and service life. However, existing bucket structures generally suffer from insufficient wear resistance during actual use, for the following reasons:

[0003] The structural design of traditional buckets is often flawed. Focusing primarily on load-bearing capacity and overall strength, they neglect wear resistance optimization. For example, critical components such as the bottom plate, side plates, and toothed seats lack effective wear protection, leading to rapid wear after prolonged use and reducing the overall service life of the bucket.

[0004] Meanwhile, if the integrated welding process experiences wear and cracking during operation, it can lead to the direct scrapping of the bucket. Therefore, existing methods lack specific protective measures. For example, when excavating soft materials such as clay and sand, the wear on the bucket is relatively minor; however, when excavating hard materials, the degree of wear increases significantly. The lack of adaptable protective design results in unsatisfactory wear resistance of the bucket under different working conditions. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this utility model provides an anti-wear structure for excavators.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: an anti-wear structure for excavators, including a bucket body, the bucket body including a left side plate and a right side plate, the left side plate and the right side plate are symmetrically arranged, the rear side of the left side plate and the right side plate are connected to a back plate, and the lower rear side of the left side plate and the right side plate are detachably connected to an arc-shaped bottom mechanism.

[0007] The arc-shaped bottom mechanism includes a left inner side plate, a right inner side plate, and an arc-shaped bottom plate at the bottom of the left inner side plate and the right inner side plate. There are at least two connecting beams between the left inner side plate and the right inner side plate. The left inner side plate is located close to the left side plate, and the right inner side plate is located close to the right side plate. There are at least two disassembly connection holes between the left inner side plate and the left side plate, and between the right inner side plate and the right side plate.

[0008] The curved base plate extends forward to form the front ends of the left and right side plates. A left anti-wear block is provided on the outer side of the front end of the left inner side plate, and the left anti-wear block protrudes from the left side plate. A right anti-wear block is provided on the outer side of the front end of the right inner side plate, and the right anti-wear block protrudes from the right side plate.

[0009] Furthermore, the back plate is provided with a connecting bracket for connecting the excavator's arm, including a first vertical plate and a second vertical plate, with a first connecting column and a second connecting column laterally connected between the first vertical plate and the second vertical plate.

[0011] Furthermore, the first connecting hole is located on the front side of both the left and right side plates. A left connecting shaft is connected to the left inner side plate near the first connecting hole, and a right connecting shaft is connected to the right inner side plate near the first connecting hole.

[0013] Furthermore, the bottom of the left inner side plate and the right inner side plate are connected to a second connecting crossbeam.

[0014] Furthermore, a third connecting beam connects the upper part of the left and right side plates.

[0015] This utility model provides a wear-resistant structure for excavators, with the following advantages:

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1;

[0026] like Figure 1 The excavator wear-resistant structure shown includes a bucket body, which includes a left side plate 1 and a right side plate 2, forming the outermost left and right guard plates. The left side plate 1 and the right side plate 2 are symmetrically arranged. The rear sides of the left side plate 1 and the right side plate 2 are connected to a back plate 5, forming a rear partition behind the left and right guard plates. The lower rear side of the left side plate 1 and the right side plate 2 is detachably connected to an arc-shaped bottom mechanism, so the arc-shaped bottom mechanism can be removed from the left side plate 1 and the right side plate 2, which is convenient for replacing more wear-resistant parts or worn parts.

[0027] Specifically, the arc-shaped bottom mechanism includes a left inner side plate 3, a right inner side plate 4, and an arc-shaped bottom plate 6 at the bottom of the left inner side plate 3 and the right inner side plate 4. Therefore, the arc-shaped bottom mechanism forms a small bucket that is partially embedded between the left side plate 1 and the right side plate 2. The reason it is partially embedded is because the arc-shaped bottom plate 6 protrudes from the lower opening of the left side plate 1 and the right side plate 2.

[0028] A first connecting beam 16 is provided between the left inner side plate 3 and the right inner side plate 4, which serves as a support and connection between the left inner side plate 3 and the right inner side plate 4. The left inner side plate 3 is located close to the left side plate 1, and the right inner side plate 4 is located close to the right side plate 2. In order to improve the tightness, a pasting installation method is usually adopted. There are two disassembly connection holes between the left inner side plate 3 and the left side plate 1, and between the right inner side plate 4 and the right side plate 2. The left inner side plate 3 and the right inner side plate 4 can be detachably connected through the installation holes. It should be understood that the connection between the two side plates can be achieved by inserting a shaft through the installation holes. This is the method adopted in this embodiment, as detailed below. However, it is also possible to directly weld on the installation holes. When disassembling, the arc-shaped bottom mechanism can be disassembled by welding the weld points.

[0029] The curved base plate 6 extends forward in an arc to form the front ends of the left side plate 1 and the right side plate 2. A left anti-wear block 7 is provided on the outer side of the front end of the left inner side plate 3, protruding from the left side plate 1. A right anti-wear block 8 is provided on the outer side of the front end of the right inner side plate 4, protruding from the right side plate 2. The left and right anti-wear blocks 7 and 8 can be made of the same material as the left and right inner side plates 3 and 4, and are connected by welding. Their shape is not limited; they can be square blocks or stepped shapes as used in this example. In short, they need to protrude on both sides to protect the left and right side plates.

[0030] like Figure 2 The back plate 5 shown is equipped with a connecting bracket for connecting the excavator's arm, including a first upright plate 9 and a second upright plate 10. A first connecting post 11 and a second connecting post 12 are laterally connected between the first upright plate 9 and the second upright plate 10. A first connecting hole A and a second connecting hole B are located symmetrically near the lower opening on the left side plate 1 and the right side plate 2. The arc-shaped bottom mechanism is detachably connected to the left side plate 1 via the first connecting hole A and detachably connected to the left side plate 1 via the second connecting hole B. The first connecting hole A is located on the front side of both the left side plate 1 and the right side plate 2, and the second connecting hole B is located on the rear side of both the left side plate 1 and the right side plate 2.

[0031] like Figure 3As shown, a left connecting shaft 13 is connected to the left inner plate 3 near the first connecting hole A, and a right connecting shaft 14 is connected to the right inner plate 4 near the first connecting hole A. The shaft extensions of both the left and right connecting shafts 13 and 14, after passing through the first connecting hole A at their respective corresponding positions, are fixed by a first collar 15. It should be understood that the first collar 15 can be fitted onto the shaft extension of either the left or right connecting shaft 13 and 14 using an interference fit, or it can be connected to the corresponding shaft extension by inserting a set screw into the first collar 15. A first connecting beam 16 is simultaneously installed at the second connecting hole B located on the rear side of both the left and right plates 1 and 2. Both shaft extensions of the first connecting beam 16 are fixed by a second collar 19, and the connection method of the second collar 19 is the same as that of the first collar 15.

[0032] Example 2;

[0033] like Figure 4 As shown, based on Embodiment 1, there are two connecting beams between the left inner plate 3 and the right inner plate 4. The bottom of the left inner plate 3 and the right inner plate 4 are connected to the second connecting beam 17, which further strengthens the connection between the left inner plate 3 and the right inner plate 4. The upper part of the left plate 1 and the right plate 2 are connected to the third connecting beam 18, which further strengthens the connection between the left plate 1 and the right plate 2.

[0034] In summary, this utility model effectively solves the problem of insufficient wear resistance of excavator buckets in the prior art by designing an anti-wear structure for excavators.

[0035] Firstly, there's the issue of optimizing the structural design: the arc-shaped bottom mechanism designed in the embodiment and its connection method with the bucket body optimize the bucket's structural design, providing effective wear-resistant protection for key components such as the bottom plate and side plates. The partially embedded design of the arc-shaped bottom mechanism significantly improves the bucket's wear resistance, especially when excavating hard materials. Through the detachable wear-resistant structural design, different wear-prone areas can be replaced, avoiding complete scrapping and extending the bucket's service life.

[0036] Secondly, it is easy to replace and maintain: because the arc-shaped bottom mechanism and the bucket body are detachably connected, when a part wears out, it can be easily replaced without replacing the entire bucket. Traditional integral welding processes require replacement of the entire bucket when wear and cracks occur, while the design of this utility model greatly reduces maintenance costs and downtime.

[0037] Finally, the connection strength is enhanced: the multiple connecting beams in Embodiment 2 further strengthen the overall connection strength of the bucket body, improving the stability and durability of the bucket. The enhanced connection structure makes the bucket less prone to deformation during prolonged use, ensuring operational efficiency and safety. It should be noted that, to ensure the connecting beam between the left and right inner side plates does not affect the spatial integrity of the bucket, a baffle is added between the left and right inner side plates to isolate the connecting beam. This baffle is located above the first connecting beam and can be a flat or curved plate. The baffle, together with the left and right side plates, forms a complete bucket space.

[0038] The advantages of this utility model include:

[0039] Improved work efficiency: Due to the improved wear resistance of the bucket, it can maintain high work efficiency under various working conditions, especially when excavating hard materials, reducing work interruptions and maintenance time caused by wear.

[0040] Reduced operating costs: The wear-resistant structure and replaceable features greatly extend the service life of the bucket and reduce long-term operating costs.

[0041] Enhanced adaptability: Through the design in the embodiment, the bucket can be equipped with wear-resistant parts made of different materials according to different working conditions, which significantly enhances the adaptability of the bucket.

[0042] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
