Description

Technical Field

[0001] This utility model relates to the field of excavator bucket technology, and in particular to a wear-resistant and impact-resistant excavator bucket. Background Technology

[0002] In mining, large-scale infrastructure projects, earthwork projects, and other operational scenarios, excavators need to frequently excavate complex materials such as hard rocks, frozen soil, and soil mixed with gravel. Under high-intensity and high-impact conditions, traditional buckets are prone to severe wear, structural deformation, and even breakage, leading to frequent equipment downtime for maintenance, affecting project progress, and increasing operating costs.

[0003] The main drawbacks of traditional excavator buckets are high friction between the bucket edge and the material, rapid wear, frequent replacement, insufficient impact resistance of the overall structure, and easy deformation and damage when encountering hard objects.

[0004] Therefore, we propose a wear-resistant and impact-resistant excavator bucket. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wear-resistant and impact-resistant excavator bucket.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wear-resistant and impact-resistant excavator bucket includes an integrated bucket, which is U-shaped in shape. Protective side plates are welded to both sides of the integrated bucket. A shock-absorbing pad is fixedly installed on one side of the integrated bucket. Quick-connect ear plates are fixedly installed on both sides of the top of the integrated bucket. Anti-collision mounting brackets are fixedly installed at both ends of the open side of the integrated bucket. A blade holder is engaged with the anti-collision mounting bracket at the bottom. Several rotating wear-resistant blades are movably arranged on the surface of the blade holder.

[0008] As a further improvement of this utility model: the opening arc of the inner wall of the integrated truck bed should be greater than or equal to 120°, and several U-shaped reinforcing plates are fixedly provided on the inner side of the integrated truck bed.

[0009] As a further improvement of this utility model: several reinforcing plates with slightly larger opening widths are fixedly arranged between the protective side plates, and form a grid structure with the reinforcing plate on the inner side of the integrated truck bed.

[0010] As a further embodiment of this utility model: the surface of the shovel holder is provided with a plurality of mounting holes, the mounting holes and the rotating wear-resistant blade are intersected, the rotating wear-resistant blade is a conical tube, and the surface of the rotating wear-resistant blade is provided with a plurality of rotating anti-slip ridges.

[0011] As a further embodiment of this utility model: a piston rod is fixedly installed on one side of the rotating wear-resistant blade, one end of the piston rod is engaged with the inner wall of the shovel holder, and a return spring is sleeved on the surface of the piston rod.

[0012] As a further improvement of this utility model: the quick-connecting ear plate is welded and fixed to the integrated truck bed, and the surface of the quick-connecting ear plate is provided with connecting holes.

[0013] As a further improvement of this utility model: the surface of the shock-absorbing pad is provided with connecting through holes, and the four corners of the shock-absorbing pad are provided with fixing holes, which are threadedly connected to one side of the protective side plate.

[0014] Compared with the prior art, this utility model provides a wear-resistant and impact-resistant excavator bucket, which has the following beneficial effects:

[0015] 1. This utility model utilizes a grid structure formed by the U-shaped reinforcing plate and the reinforcing plate between the protective side plates, fundamentally enhancing the overall rigidity and deformation resistance of the bucket. The rotating wear-resistant blades arranged in an alternating pattern on the surface of the blade holder employ conical tubes with anti-slip ridges. This unique design generates rolling friction when the blade contacts the material, greatly reducing the wear rate. The rotating wear-resistant blades, through a combination of piston rod and return spring, achieve elastic buffering under impact, avoiding blade damage caused by rigid collisions and significantly extending the service life of key bucket components.

[0016] 2. In this utility model, the protective side plates on both sides of the bucket and the anti-collision mounting frame form an outer protective barrier, which can resist impacts from the side and front, reducing the risk of damage to the main body of the bucket. The shock-absorbing pads absorb high-frequency vibrations during excavation, reducing fatigue damage to the bucket. The quick-connect ear plate design facilitates rapid assembly and disassembly of the bucket and excavator boom, improving the equipment's versatility and maintenance efficiency. The blade holder adopts a snap-fit ​​installation, allowing worn parts to be replaced independently, further reducing maintenance and time costs.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: A wear-resistant and impact-resistant excavator bucket, such as Figures 1-4As shown, the integrated truck bed 1 is U-shaped. Protective side plates 2 are welded to both sides of the integrated truck bed 1. A shock-absorbing pad 3 is fixedly installed on one side of the integrated truck bed 1. Quick-connect ear plates 4 are fixedly installed on both sides of the top of the integrated truck bed 1. Anti-collision mounting brackets 5 are fixedly installed at both ends of the opening side of the integrated truck bed 1. A scraper frame 6 is engaged with the anti-collision mounting bracket 5 at the bottom. Several rotating wear-resistant blades 7 are movably installed on the surface of the scraper frame 6. The opening curvature of the inner wall of the integrated truck bed 1 should be greater than or equal to 120°. Several U-shaped reinforcing plates 8 are fixedly installed on the inner side of the integrated truck bed 1. The grid structure formed by the U-shaped reinforcing plates 8 and the reinforcing plates 8 between the protective side plates 2 fundamentally enhances the overall rigidity and deformation resistance of the truck bed. The rotating wear-resistant blades 7 arranged in an alternating pattern on the surface of the shovel holder 6 adopt a conical tube body with anti-slip ridges 15. This unique design causes rolling friction when the blade comes into contact with the material, which greatly reduces the wear rate. The rotating wear-resistant blades 7 achieve elastic buffering when subjected to impact through the combination of piston rod 9 and return spring 10, avoiding damage to the blade edge caused by rigid collision and significantly extending the service life of key components of the bucket.

[0026] like Figures 1-4 As shown, several reinforcing plates 8 with slightly larger openings are fixedly installed between the protective side plates 2, and form a grid structure with the reinforcing plate 8 on the inner side of the integrated truck bed 1. Several mounting holes 14 are opened on the surface of the shovel holder 6. The mounting holes 14 and the rotating wear-resistant blade 7 are intersected. The rotating wear-resistant blade 7 is a conical tube. Several rotating anti-slip ridges 15 are opened on the surface of the rotating wear-resistant blade 7.

[0027] like Figures 1-3 As shown, a piston rod 9 is fixedly installed on one side of the rotating wear-resistant blade 7. One end of the piston rod 9 is engaged with the inner wall of the shovel holder 6. A return spring 10 is sleeved on the surface of the piston rod 9. The quick-connect ear plate 4 is welded and fixed to the integrated truck bed 1. The surface of the quick-connect ear plate 4 is provided with a connecting hole 11. The surface of the shock-absorbing pad 3 is provided with a connecting through hole 12. The four corners of the shock-absorbing pad 3 are provided with fixing holes 13. The fixing holes 13 are threaded to one side of the protective side plate 2.

[0028] Working Principle: During operation, the bucket cuts into the material driven by the excavator. The rotating wear-resistant blade 7 cuts the material with its anti-slip edges 15. Its unique rotating structure reduces friction with the material, thus reducing wear. When encountering a hard object and impacting it, the rotating wear-resistant blade 7 compresses the return spring 10 through the piston rod 9, converting the impact force into the elastic potential energy of the spring, thus buffering the impact. After the impact, the spring returns to its original position, allowing the blade to continue working. The integrated bucket 1 and the reinforcing plate 8 form a grid structure that evenly distributes the stress transmitted to the bucket, preventing localized deformation. The protective side plates 2 and the anti-collision mounting bracket 5 provide external protection for the bucket, while the shock-absorbing pad 3 absorbs vibrations generated during excavation, reducing bucket fatigue. The quick-connect ear plate 4 ensures a stable connection between the bucket and the excavator and facilitates easy assembly and disassembly, ensuring smooth operation.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
