Description

Technical Field

[0001] This utility model relates to the field of bucket technology, and in particular to a bucket blade structure that is easy to replace. Background Technology

[0002] In engineering construction, mining, and agricultural production, the bucket, as a key component of machinery, directly undertakes the important tasks of digging, cutting, and loading materials. Traditionally, bucket cutting edges are connected to the bucket body via integral welding or bolting. This structure has significant drawbacks in practical use. Firstly, welded cutting edges are difficult to replace after wear, requiring complex disassembly processes such as cutting, which is not only time-consuming and labor-intensive but also prone to damaging the bucket body. Secondly, while bolted connections are easy to disassemble, frequent assembly and disassembly can lead to wear of the bolt holes and loosening of the connection, affecting safety and reliability.

[0003] As modern engineering demands ever higher construction efficiency, prolonged high-intensity operations exacerbate wear on bucket cutting edges, leading to a significant increase in replacement frequency. Traditional replacement methods are complex, often resulting in extended equipment downtime, severely impacting construction progress and increasing maintenance costs. Furthermore, cutting edges made of a single material cannot simultaneously meet multiple performance requirements such as wear resistance, impact resistance, and corrosion resistance, making them unsuitable for complex working conditions such as high-hardness rocks in mines and highly corrosive soils in wetlands.

[0004] Existing bucket cutting edges are mostly made of a single material, making it difficult to balance high wear resistance and toughness. They are prone to cracking when excavating hard rock, and face corrosion problems when operating in humid or acidic / alkaline environments. As the intensity and complexity of engineering operations continue to increase, traditional bucket cutting edge structures can no longer meet the requirements of rapid replacement, efficient operation, and long service life. Therefore, a bucket cutting edge structure that is easy to replace is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figures 1 to 4 This utility model provides an embodiment of a conveniently replaceable bucket blade structure, including a supporting bucket 1. A fixing mechanism 2 is fixedly connected externally to the supporting bucket 1. A multi-layer composite mechanism 3 is fixedly connected internally to the fixing mechanism 2. The multi-layer composite mechanism 3 is externally fixedly connected to the outside of the supporting bucket 1. The fixing mechanism 2 includes a drive assembly 201, and a threaded rotating column 203 is fixedly connected externally to the drive assembly 201. This converts rotational motion into linear motion, driving the supporting fixing plate 209 to move up and down through rotation, thereby driving the subsequent connecting and rotating components to operate, achieving multi-layer... The connection or separation of the composite mechanism 3 and the supporting bucket 1, the top of the threaded rotating column 203 is fixedly connected to the second supporting plate 209, which serves as a connection and support component, and three connecting blocks 208 are fixed thereon, which move with the up and down movement of the threaded rotating column 203, providing support and a basis for the rotation of the rotating connecting rod 206. The outside of the second supporting plate 209 is fixedly connected to three connecting blocks 208, which serve as the rotation fulcrum of the rotating connecting rod 206, converting the linear motion of the second supporting plate 209 into the rotational motion of the rotating connecting rod 206, thus playing the role of force transmission and conversion.

[0034] The connecting fixing block 208 is externally rotatably connected to two rotating connecting rods 206. These rods, through rotation, transmit the motion of the connecting fixing block 208 to the rotating fixing plate 207, changing the direction and point of application of the force. This enables the connection and separation of the multi-layer composite mechanism 3 and the supporting bucket 1. The rotating fixing plate 207 is rotatably connected to the outer end of the rotating connecting rod 206, i.e., the end furthest from the connecting fixing block 208. This plate connects the rotating connecting rod 206, the supporting fixing block 2010, and the connecting fixing plate 204, converting the rotational motion of the rotating connecting rod 206 into the motion of the supporting fixing block 2010 and the connecting fixing plate 204. This enables the fixing and releasing of the multi-layer composite mechanism 3. The rotating fixing plate 207 is externally fixedly connected to the supporting fixing block 201. 0. The rotating fixed plate 207 is externally rotatably connected to the connecting fixed plate 204, which connects the rotating fixed plate 207 and the multi-layer composite mechanism 3, and transmits the movement of the rotating fixed plate 207 to the multi-layer composite mechanism 3, so as to realize the connection and fixation of the multi-layer composite mechanism 3 and the supporting bucket 1. The internal fixed connection of the connecting fixed plate 204 is a rotating support column 205, which provides rotational support for the connecting fixed plate 204, ensuring that the connecting fixed plate 204 can rotate around it, making the movement of the fixing mechanism 2 more flexible and stable. The bottom of the connecting fixed plate 204 is fixedly connected to the supporting fixed plate 202, which serves as a connection and support component, and externally fixes the connecting fixed plate 204 to the multi-layer composite mechanism 3, thereby enhancing the stability and reliability of the connection.

[0035] The external fixed connection of the support fixing plate 202 is to the outside of the multi-layer composite mechanism 3. The drive assembly 201 includes a rotary motor 20101, which serves as a power source to provide driving force for the movement of the entire fixing mechanism 2, converting electrical energy into mechanical energy. The external fixed connection of the drive assembly 201 is to the outside of the support bucket 1. The drive end of the rotary motor 20101 is fixedly connected to a rotary support column 20102, which transmits the rotational power of the rotary motor 20101 to the threaded rotary column 203, while also providing support and positioning to ensure that the threaded rotary column 203 can rotate stably. The external fixed connection of the rotary motor 20101 is to the outside of the support bucket 1. At the bottom of the multi-layer composite mechanism 3, the interior of the rotating support column 1 20102 is rotatably connected to the exterior of the threaded rotating column 203, the exterior of the connecting fixing plate 204 is fixedly connected to the interior of the multi-layer composite mechanism 3, the exterior of the rotating fixing plate 207 is rotatably connected to the exterior of the multi-layer composite mechanism 3, the exterior of the rotating connecting rod 206 is rotatably connected to the exterior of the multi-layer composite mechanism 3, the exterior of the support fixing block 2010 is rotatably connected to the exterior of the support bucket 1, the exterior of the rotating support column 205 is rotatably connected to the interior of the multi-layer composite mechanism 3, and the exterior of the rotating support column 1 20102 is rotatably connected to the interior of the multi-layer composite mechanism 3.

[0036] Reference Figure 1 , Figure 3 and Figure 5The multi-layer composite structure 3 includes a waterproof and wear-resistant layer 301. The multi-layer composite structure 3 is composed of multiple layers with different functions, which cooperate with each other. The waterproof and wear-resistant layer 301 is externally fixedly connected to the outside of the supporting bucket 1, located at the innermost layer of the multi-layer composite structure 3, and directly in contact with the supporting bucket 1. It serves to provide waterproofing and wear resistance, preventing moisture and materials from eroding and abrading the supporting bucket 1, thus extending the service life of the supporting bucket 1. A buffer connection layer 302 is externally fixedly connected to the waterproof and wear-resistant layer 301. The buffer connection layer 302 is located between the waterproof and wear-resistant layer 301 and the supporting connection layer 303, serving as a buffer and connection. The supporting connection layer 303 is externally fixedly connected to the buffer connection layer 302, acting as the main supporting structure of the multi-layer composite structure 3, connecting the layers together and ensuring the stability of the multi-layer composite structure 3. To ensure overall stability, a connecting toughness layer 304 is fixedly connected to the outside of the supporting connecting layer 303. The connecting toughness layer 304 is located between the supporting connecting layer 303 and the second waterproof and wear-resistant layer 305, serving to connect and enhance toughness. The second waterproof and wear-resistant layer 305 is fixedly connected to the outside of the connecting toughness layer 304, located on the outermost layer of the multi-layer composite structure 3, directly contacting the material, serving to provide waterproofing and wear resistance, protecting the internal layers from erosion and wear by moisture and materials, and extending the service life of the multi-layer composite structure 3. The second waterproof and wear-resistant layer 305 is fixedly connected to the outside of the supporting bucket 1, the outside of the supporting connecting layer 303 is fixedly connected to the outside of the supporting bucket 1, the outside of the connecting toughness layer 304 is fixedly connected to the outside of the supporting bucket 1, and the outside of the buffer connecting layer 302 is fixedly connected to the outside of the supporting bucket 1.

[0037] Working principle: When the rotating motor 20101 starts running, it drives the rotation of the rotating support column 20102, which in turn drives the rotation of the threaded rotating column 203. This causes the second supporting fixing plate 209 to move upward, which in turn drives the connecting fixing block 208 and the rotating connecting rod 206 to move upward. This causes the rotating fixing plate 207 and the supporting fixing block 2010 to move outward, thus achieving an outward fixing effect. At the same time, the connecting fixing plate 204 and the second rotating support column 205 provide rotation for the rotation of the rotating fixing plate 207, thus achieving an outward fixing effect.

[0038] When the multi-layer composite structure 3 is working, the innermost waterproof and wear-resistant layer 301 is in contact with the supporting bucket 1 to prevent moisture and materials from eroding and wearing the bucket. The buffer connecting layer 302 is located between the waterproof and wear-resistant layer 301 and the supporting connecting layer 303. It absorbs the impact force during digging through elastic deformation. The supporting connecting layer 303, as the main body, provides structural support with high-strength materials, firmly connects the layers, and ensures overall stability. The connecting toughness layer 304 enhances the structural toughness and improves the resistance to deformation. The outermost waterproof and wear-resistant layer 305 is in direct contact with the material, resists friction and impact, protects the internal structure, and ensures the stable operation of the bucket blade under complex working conditions.

[0039] 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.
