Description

A detachable excavator bucket backfilling and bulldozing efficiency enhancement device Technical Field

[0001] This utility model relates to the field of excavator bucket technology, specifically to a detachable excavator bucket backfilling and bulldozing efficiency enhancement device. Background Technology

[0002] Excavator buckets are primarily used for earthmoving and backfilling operations, with a focus on improving structural strength and excavation efficiency. However, optimization for backfilling operations is insufficient. Traditional buckets, due to their curved or locally concentrated contact surface design, result in soil dispersion during fine trench backfilling, requiring repeated operations and leading to low efficiency. In related technologies, optimized structures for bucket backfilling include scrapers. However, scrapers often employ fixed welding or complex hinged connections, resulting in cumbersome installation, compatibility issues, and the need for complete replacement after wear, leading to high costs. Therefore, excavator buckets suffer from uneven soil distribution and insufficient efficiency during backfilling operations. Summary of the Invention

[0003] The purpose of this utility model is to provide a detachable excavator bucket backfilling and bulldozing efficiency enhancement device to solve the problems of uneven soil distribution and low efficiency of excavator bucket backfilling devices in backfilling operations.

[0004] To achieve the above objectives, the present invention provides a detachable excavator bucket backfilling and bulldozing efficiency enhancement device, which adopts the following technical solution:

[0005] A detachable excavator bucket backfilling and bulldozing efficiency enhancement device includes a bulldozer blade and a reinforcing wing plate. Two reinforcing wing plates are provided and are vertically fixedly connected to the same surface of the bulldozer blade. Fasteners are provided on the reinforcing wing plates for connecting the reinforcing wing plates to the side wall of the bucket. Ribs are fixedly connected to the joint between the reinforcing wing plates and the bulldozer blade.

[0006] As an optimization of a detachable excavator bucket backfilling and bulldozing efficiency enhancement device, at least three fasteners are provided on the same reinforcing wing plate, wherein the three fasteners are arranged in an isosceles triangle on the reinforcing wing plate.

[0007] As an optimization of a detachable excavator bucket backfilling and bulldozing efficiency enhancement device, a contour pad is fixedly connected to the side of the bulldozer blade near the reinforcing wing plate. The contour pad is used to fill the gap between the bulldozer blade and the bucket.

[0008] As an optimization of a detachable excavator bucket backfilling and bulldozing efficiency enhancement device, the thickness of the bulldozing blade includes at least 20mm, 25mm and 30mm.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] (1) Detachable design significantly improves maintenance efficiency: Fasteners enable quick assembly and disassembly of the reinforced blades and bucket sidewalls, solving the problems of cumbersome installation and poor adaptability of traditional welding or complex hinged structures. It facilitates the individual replacement of locally worn parts, reducing maintenance costs and downtime. The bulldozer blades increase the working contact area of ​​the bucket by 40%-60%, significantly improving the uniformity of earthwork backfilling and the efficiency of single operation.

[0011] (2) Structural stability and torsional performance optimization: The rib design at the joint between the reinforced wing plate and the bulldozer blade forms a dual stress transmission path. Combined with the fastener configuration of the three-point isosceles triangle distribution, the load is effectively dispersed and stress concentration is reduced, which greatly improves the overall rigidity and torsional performance of the device and ensures operational stability.

[0012] (3) Enhanced adaptability and operational efficiency: The thickness of the bulldozer blade can be flexibly matched according to the soil type, expanding the versatility of the device.

[0013] (4) Uniformly Distribute Load: A contour pad structure is added between the bulldozer blade and the bucket to achieve uniform pressure distribution by filling the gap, thereby increasing the effective contact area between the bucket and the bulldozer blade and making the load uniformly distributed.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0021] The present application will be further described in detail below with reference to Figures 1-2.

[0022] This application provides a detachable excavator bucket backfilling and bulldozing efficiency enhancement device, which adopts the following technical solution:

[0023] Referring to Figures 1 and 2, the detachable excavator bucket 10 backfilling and bulldozing efficiency enhancement device includes a bulldozer blade 1 and reinforcing wing plates 2. The bulldozer blade 1 is rectangular and made of Q235B steel. The length of the bulldozer blade 1 is greater than the width of the bucket 10, and the width of the bulldozer blade 1 at least covers the teeth of the bucket 10, increasing the effective contact area of ​​the working surface by 40%-60%. The reinforcing wing plates 2 are trapezoidal and made of Q345B steel. There are two reinforcing wing plates 2, which are perpendicular to the same surface of the bulldozer blade 1. The bottom edge of the reinforcing wing plate 2 is welded to the bulldozer blade 1 through a continuous fillet weld to achieve full circumferential penetration. Two reinforcing wing plates 2 are located on both sides of the bucket 10. Each reinforcing wing plate 2 is equipped with a fastener 3, which can be a bolt or screw. In this embodiment, the fastener 3 is an 8.8 grade high-strength bolt. The reinforcing wing plate 2 is detachably connected to the side wall of the bucket 10 via the fastener 3. A rib plate 4 is welded to the joint between the reinforcing wing plate 2 and the bulldozer blade 1. The rib plate 4 is an isosceles right triangle, and its thickness matches the strength of the main component. The fillet weld between the rib plate 4 and the lower edge of the reinforcing wing plate 2 forms a dual stress transmission path, evenly transferring the load of the reinforcing wing plate 2 to the bulldozer blade 1, thereby improving the torsional stiffness of the structure. During installation, the bulldozer blade 1 abuts against the outer side of the bucket teeth of the bucket 10, and the reinforcing wing plate 2 is fixedly installed on the side wall of the bucket 10. The fit between the reinforcing wing plate 2 and the side wall of the bucket 10 is calibrated using a laser positioning device, ensuring structural reliability while achieving dynamic collaborative operation between the bulldozer blade 1 and the bucket 10.

[0024] In a preferred embodiment of this application, referring to FIG2, at least three fasteners 3 are installed on the same reinforcing wing plate 2, wherein the three fasteners 3 are arranged in an isosceles triangle on the reinforcing wing plate 2. By having at least three non-collinear fasteners 3 act simultaneously on the contact surface between the reinforcing wing plate 2 and the side wall of the bucket 10, a three-point constraint is achieved, which can improve the stability of the connection between the reinforcing wing plate 2 and the side wall of the bucket 10. At the same time, the isosceles triangle arrangement makes the shear stress distribution among the three fasteners 3 more uniform, avoids stress concentration in a single fastener 3, and helps to improve the service life of the fasteners 3.

[0025] In a preferred embodiment of this application, referring to Figures 1 and 2, a contour pad 5 is bonded and fixed to the side of the bulldozer blade 1 near the reinforcing wing plate 2. The contour pad 5 can be a rubber pad or a high-density polyurethane foam, or a cloth bag filled with crushed particles such as sand or sawdust. The contour pad 5 deforms under pressure and wraps around the outer periphery of the object being pressured. When the bucket 10 contacts the bulldozer blade 1, the bucket 10 compresses the contour pad 5, and the contour pad 5 wraps around the outside of the bucket 10, filling the gap between the bulldozer blade 1, the bucket teeth, and the curved surface of the bucket 10, thereby increasing the effective contact area between the bucket 10 and the bulldozer blade 1 and making the pressure of the bucket 10 more dispersed.

[0026] In a preferred embodiment of this application, the thickness of the bulldozer blade 1 includes at least 20mm, 25mm, and 30mm. In actual production applications, considering both manufacturing costs and structural rigidity, a thickness of 20mm is suitable for sandy soil, a thickness of 25mm is suitable for clay, and a thickness of 30mm is suitable for gravel-mixed strata. By adjusting the thickness of the bulldozer blade 1, different soil hardness requirements can be met.

[0027] The experimental principle of this application embodiment is as follows: When backfilling is required using an excavator, the bucket 10 transfers the load to the bulldozer blade 1 through the reinforcing wing plate 2 and rib plate 4, increasing the effective working area. The bulldozer blade 1 pushes and pulls the soil and performs backfilling operations, increasing the uniformity of soil pressure and improving the efficiency of single backfilling. At the same time, the bulldozer blade 1 directly contacts the ground layer instead of the bucket 10, which protects the bucket 10, reduces the wear rate of the bucket 10, and effectively extends the equipment life of the bucket 10.

[0028] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
