Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery components technology, specifically to an excavator bucket assembly structure. Background Technology
[0002] In the field of modern engineering construction, excavators, with their powerful digging and loading capabilities, have become core mechanical equipment in many projects such as infrastructure construction, mining, and farmland irrigation improvement. As the component of the excavator that directly contacts materials and completes key operations such as digging, loading, and unloading, the performance of the bucket directly affects the efficiency, quality, and cost of engineering construction.
[0003] The existing technology has the following defects or problems: Existing technology, publication number CN218814009U, relates to an excavator bucket, including a bucket body, a bucket connecting shaft, and a quick-change bucket tooth assembly. The bucket connecting shaft is welded to the rear top of the bucket body. A reserved position is provided on the front side of the bottom end of the bucket body. The quick-change bucket tooth assembly is fixed in the reserved position on the front end side of the bucket body by large and small long shaft pins. The front end of the inner bottom side of the bucket body has neat protrusions and neat grooves, which are spaced apart from each other. This utility model optimizes the structural design of the excavator bucket, changing the traditional one-piece excavator bucket structure to a detachable and separable excavator bucket structure. The structure is designed with a quick-change bucket tooth assembly that can be disassembled quickly. Not only can the bucket teeth be replaced and disassembled individually, but the front end plate of the bucket teeth can also be replaced, reducing the cost of replacing the entire bucket and improving replacement efficiency. It is suitable for widespread use.
[0004] During use, the aforementioned equipment is prone to local deformation and cracking under the long-term impact, compression, and excavation resistance of materials, leading to premature damage to the bucket. Frequent bucket replacement not only increases maintenance costs but also causes equipment downtime and affects project progress. However, in the existing technology, some excavator bucket combination structures, when excavating hard strata, frozen soil, or hard rock materials, often require additional crushing equipment for pretreatment due to the lack of an effective crushing device. This not only increases construction procedures and time costs but also reduces overall construction efficiency.
[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content
[0006] In view of the shortcomings of the existing technology, this utility model provides an excavator bucket combination structure, which solves the existing problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an excavator bucket assembly structure, comprising a bucket body, a connecting lug fixedly connected to the top of the bucket body, a bucket cavity opened on the left side of the bucket body, multiple reinforcing blocks fixedly connected to the front and rear sides of the right side of the bucket body, multiple filter grooves opened at the front and rear ends of the right side of the bucket body, two crossbars fixedly connected to the front and rear ends of the left side of the bucket body, two clamping plates provided at the top left side of the bucket body, multiple fixing bolts fixedly connected inside the two clamping plates, multiple protrusions fixedly connected inside the bucket body, guide teeth fixedly connected to the left side of the multiple protrusions, and multiple crushing components provided on the left side of the bucket body.

[0014] Compared with the prior art, this utility model provides an excavator bucket assembly structure, which has the following beneficial effects:
[0015] 1. An excavator bucket assembly structure, comprising a bucket body, connecting lugs, reinforcing blocks, a filter groove, a crossbar, a clamping plate, and a ridge. The bucket body is the main structure, with a digging chamber on the left side and the right side connected to the excavator arm via the connecting lugs. The connecting lugs are fixed to the top right side of the bucket to withstand the tension and torque during digging, ensuring stable operation of the bucket. The reinforcing blocks are distributed at the front and rear ends of the right side of the bucket to enhance the structural strength of the right side, resist lateral stress during digging, and prevent deformation. The filter groove allows mud, sand, or fine materials to be discharged through the filter groove, reducing the ineffective load inside the bucket. The clamping plate, fixing bolts, and crossbar provide structural support, and the ridge protects the inner wall of the bucket from wear by hard objects. Thus, through the coordinated work of each part, efficient digging and material handling are achieved.

[0023] 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.
[0024] Example 1
[0025] Please see Figure 1-5 In this embodiment: an excavator bucket assembly structure includes a bucket body 1, a connecting lug 2 fixedly connected to the top of the bucket body 1, the bottom end of the connecting lug 2 fixedly connected to the top right side of the bucket body 1, a bucket cavity 3 opened on the left side of the bucket body 1, multiple reinforcing blocks 4 fixedly connected to the front and rear sides of the right side of the bucket body 1 respectively, the adjacent sides of the multiple reinforcing blocks 4 fixedly connected to the front and rear ends of the right side of the bucket body 1 respectively, multiple filter grooves 5 opened at the front and rear ends of the right side of the bucket body 1 respectively, and the front and rear ends of the left side of the bucket body 1 are fixedly connected to... There are two crossbars 6, and the adjacent sides of the multiple crossbars 6 are fixedly connected to the front and rear ends of the left side of the bucket body 1. Two clamping plates 7 are provided at the top left side of the bucket body 1. The inner walls of the two clamping plates 7 are in contact with the inner walls of the front and rear sides of the bucket body 1. Multiple fixing bolts 8 are fixedly connected inside the two clamping plates 7. Multiple protruding strips 9 are fixedly connected inside the bucket body 1. The bottom ends of the multiple protruding strips 9 are fixedly connected to the bottom inner wall of the bucket body 1. Guide teeth 10 are fixedly connected to the left side of the multiple protruding strips 9. Multiple crushing components are provided on the left side of the bucket body 1.
[0026] In this embodiment, the connecting lug 2 at the top of the bucket body 1 is a key connecting component between the bucket and the excavator arm. The connecting lug 2 is hinged to the corresponding part of the excavator arm via connecting components such as pins. During excavation, the bucket is subjected to various external forces, including material impact, compression, and excavation resistance, especially the right side, which is prone to stress concentration due to uneven force distribution. The reinforcing block 4 effectively prevents deformation and cracking of the bucket body 1 by dispersing these external forces, extending the bucket's service life and ensuring its stability and reliability under heavy-load, high-intensity operating environments. Multiple filter grooves 5 at the front and rear ends of the right side of the bucket body 1 are mainly used for rapid drainage and filtration when excavating materials containing water. When the bucket is full of material and lifted away from the working surface, the water will be discharged from the bucket cavity 3 through the filter grooves 5 under gravity. The filter grooves 5 prevent excessive water retention in the bucket, reducing the overall weight of the bucket, lowering excavator energy consumption, and preventing water from accumulating in the material. Excessive load may overflow or scatter during transportation, improving operational efficiency and safety; the crossbar 6 enhances the structural strength of the rear and bottom of the bucket, improving the bucket's resistance to load fatigue; the clamping plate 7 prevents the side plates of the bucket body 1 from deforming or being damaged due to excessive force during digging; multiple protrusions 9 inside the bucket body 1 increase the friction between the inner wall of the bucket and the material, preventing the material from sliding inside the bucket and ensuring stable loading; the guide tooth 10 on the left side of the protrusion 9 guides the material during digging, allowing it to enter the bucket cavity 3 more smoothly and reducing digging resistance.
[0027] Example 2
[0028] like Figure 1 - Figure 5 As shown, the multiple crushing components each include crushing teeth 12. The right side of the crushing teeth 12 is provided with an installation groove 13. The installation groove 13 is provided with a connecting block 11. The right side of the multiple connecting blocks 11 is fixedly connected to the bottom left side of the bucket body 1. The outer bottom of the multiple connecting blocks 11 is in contact with the inner right side of the multiple crushing teeth 12. The right side of the crushing teeth 12 is fixedly connected with a bolt 14. The outer side of the multiple bolts 14 is threadedly connected to the inner wall of the multiple connecting blocks 11.
[0029] In this embodiment, during installation, the mounting groove 13 of the breaking tooth 12 is fitted into the connecting block 11, and then the bolt 14 is used to pass through the breaking tooth 12 and threadedly connected to the inner wall of the connecting block 11. By tightening the bolt 14, the breaking tooth 12 is firmly fixed to the bucket body 1. This threaded connection method not only facilitates the disassembly and replacement of worn breaking teeth 12, but also allows it to withstand huge impact forces and torques during excavation operations, ensuring that the breaking tooth 12 will not loosen or fall off under complex working conditions. When the excavator excavates hard materials such as hard strata, frozen soil, or rocks, the hydraulic system drives the mechanical arm to move the bucket, and the breaking tooth 12 impacts the material at a certain speed and angle. Since the breaking tooth 12 is made of high-strength alloy material, it has good wear resistance and impact toughness, and can withstand the reaction force of the material without being easily damaged. At the moment of contact with the material, the breaking tooth 12 converts the mechanical energy transmitted by the excavator into breaking force, and destroys the material through chiseling, splitting, and other methods. During the continuous excavation process, the crushing teeth 12 repeatedly impact and crush, gradually breaking large, hard materials into smaller pieces, making the materials easier to load and transport by the bucket.
[0030] The working principle and usage process of this utility model are as follows: The bucket body 1 is connected to the excavator arm through the connecting lug 2. The material is cut into the left bucket cavity 3, the right reinforcing block 4 bears the digging resistance, the filter groove 5 filters fine materials or drains water, the guide tooth 10 cuts large pieces of material, and the convex strip 9 guides the material to flow into the inside of the bucket. During the digging process, the crushing teeth 12 cut into the material with the movement of the bucket, tearing or crushing large rocks or frozen soil. The clamping plate 7, the fixing bolt 8 and the crossbar 6 provide structural support. The convex strip 9 and the guide tooth 10 work together to make the crushed material slide into or out along the inner wall of the bucket. The filter groove 5 avoids too much water remaining in the bucket, reduces the overall weight of the bucket, and reduces the energy consumption of the excavator.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
