Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and in particular to an excavator bucket structure that can remove fine powder from earth-rock dam materials. Background Technology

[0002] Currently, the scale of earth-rock dam construction is constantly expanding, and the requirements for stone quality are becoming increasingly stringent. Large earth-rock dam projects often require millions or even tens of millions of cubic meters of high-quality stone. Taking the construction of an earth-rock dam for a large water conservancy project as an example, the total amount of stone required is as high as tens of thousands of cubic meters. If fine powder cannot be effectively removed, it will not only increase the project cost, but may also cause delays in the construction period due to quality problems. Conventional stone screening methods are mostly carried out in a special screening site with the help of large screening equipment after the stone is excavated. This method is not only cumbersome and requires a lot of manpower and material resources for stone transportation, but also has low screening efficiency, which is difficult to meet the progress requirements of large-scale earth-rock dam construction. At the construction site, stone supply shortages often occur due to screening equipment failure or insufficient processing capacity, causing the project to stagnate.

[0003] While the continuous development of excavator technology has significantly improved the excavation efficiency and durability of buckets, there are still shortcomings in the function of removing fine powder from earth-rock dam materials. Existing bucket structures mainly focus on excavation capacity, with little consideration given to the function of simultaneously removing fine powder during the excavation process. This makes it difficult to efficiently and accurately obtain stone materials that meet quality requirements in the stone mining stage of earth-rock dams. Therefore, developing an excavator bucket structure that can remove fine powder from earth-rock dam materials is of great practical significance for improving the construction quality of earth-rock dams, accelerating the project progress, and reducing construction costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an excavator bucket structure that can remove fine powder from earth-rock dam materials. It aims to improve the existing technology where the bucket structure mainly focuses on digging capacity and pays little attention to the function of removing fine powder during the digging process. This makes it difficult to efficiently and accurately obtain stone materials that meet quality requirements in the earth-rock dam material mining process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an excavator bucket structure for removing fine powder from earth-rock dam materials, comprising a bucket, wherein multiple grid holes are provided on the rear side of the outer wall of the bucket, and a first reinforcing steel plate is fixedly connected between adjacent grid holes, a second reinforcing steel plate is fixedly connected to the bottom of the first reinforcing steel plate, bucket teeth are fixedly connected to the bottom right side of the bucket, and a connecting steel plate is fixedly connected to the top right side of the bucket.

[0006] As a further description of the above technical solution:

[0007] The bucket teeth are designed in a quasi-conical shape and are fixedly connected at the same horizontal level.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the connecting steel plate has a reserved hole, and the inner side of the reserved hole is connected to a bolt.

[0010] As a further description of the above technical solution:

[0011] The multiple grille holes are circular in design and are arranged symmetrically.

[0012] As a further description of the above technical solution:

[0013] Both connecting steel plates are symmetrically designed.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the bucket is used as the main structure and is made of high-strength material. The connecting steel plate securely connects the bucket to the excavator arm, ensuring that it can withstand huge tensile and impact forces during excavation. The pre-drilled holes facilitate the installation of the bucket and ensure the bucket's gripping force on the stone during excavation. The bucket teeth, as the part that directly contacts the soil and rocks, are made of high hardness, which not only efficiently crushes the stone material in the earth-rock dam but also reduces the impact on the bucket body during excavation. This comprehensively ensures that the bucket has high strength, extends its service life, and effectively protects the fine powder of the stone material in the earth-rock dam.

[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 the appendix Figure 1 - Appendix Figure 2 The present invention provides an embodiment of an excavator bucket structure for removing fine powder from earth-rock dam materials, comprising a bucket 1, with multiple grid holes 4 provided on the rear side of the outer wall of the bucket 1, and a reinforcing steel plate 5 fixedly connected between adjacent grid holes 4, a reinforcing steel plate 7 fixedly connected to the bottom of the reinforcing steel plate 5, bucket teeth 6 fixedly connected to the bottom right side of the bucket 1, and a connecting steel plate 2 fixedly connected to the top right side of the bucket 1, wherein the multiple grid holes 4 are circular in design and are symmetrically arranged;

[0022] Specifically, the reasonable layout of these grid holes 4 effectively reduces the weight of the bucket 1. At key locations between adjacent grid holes 4, reinforcing steel plates 5 are firmly fixedly connected, forming a robust framework. Further reinforcing steel plates 7 are fixedly connected to the bottom of these plates, working in tandem. The bottom right side of the bucket 1 is the critical area directly in contact with soil and rock during excavation. Multiple bucket teeth 6 are evenly fixedly connected here. These high-strength teeth can easily break hard soil and rock, ensuring smooth excavation. A connecting steel plate 2 is fixedly connected to the top right side of the bucket 1. The connecting steel plate 2 has precise mounting holes, allowing the bucket 1 to be securely connected to the excavator's robotic arm, ensuring stable and reliable collaborative operation between the bucket 1 and the robotic arm during excavation.

[0023] Please see the appendix Figure 1 - Appendix Figure 2 The outer wall of the connecting steel plate 2 is provided with a reserved hole 3, and the inner side of the reserved hole 3 is connected with a bolt. The bucket tooth 6 is designed as a quasi-conical design and is fixedly connected at the same horizontal height. Both connecting steel plates 2 are symmetrically treated.

[0024] Specifically, the bucket 1 is tightly connected to the excavator's robotic arm via a connecting steel plate 2. The outer wall of the bucket 1 has pre-drilled holes 3. By precisely passing bolts through these holes 3 and tightening them with nuts, a stable and reliable connection between the bucket 1 and the robotic arm can be achieved. This ensures that the bucket 1 can withstand enormous tensile and impact forces without loosening or falling off during the excavation process. At the same time, all the bucket teeth 6 are fixedly connected at the same horizontal height. This design ensures that each bucket tooth 6 can be evenly stressed during the excavation process, preventing premature damage to some bucket teeth 6 due to uneven stress, thereby ensuring the stability and continuity of the excavation operation.

[0025] Working Principle: The bucket 1 serves as the main structure, made of high-strength materials. Connecting steel plates 2 securely link the bucket 1 to the excavator's mechanical arm, ensuring it can withstand immense tensile and impact forces during excavation. Pre-drilled holes 3 facilitate the installation of the bucket 1. The grid holes 4 effectively remove some fine powder from the earth-rock dam material while maintaining the bucket 1's gripping force during excavation. Reinforcing steel plates 5 and 7 are welded to the stress-bearing parts of the bucket 1, along with the side plates and bottom, significantly improving the bucket 1's resistance to deformation and fracture. The bucket teeth 6, directly in contact with the soil and rock, are made of high-hardness material, efficiently crushing the earth-rock dam material while reducing impact on the main body of the bucket 1 during excavation. This comprehensive approach ensures the bucket 1 maintains high strength, extends its service life, and effectively protects the fine powder from the earth-rock dam material.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
