Description

Technical Field

[0001] This utility model relates to the field of bucket technology, specifically to a wear-resistant large bucket for heavy-duty operations. Background Technology

[0002] The bucket is a core operating component of excavators and other machinery. It consists of parts such as the tooth base plate, bottom plate, bottom reinforcement plate, side plates, wall plates, lug plates, back plate, bucket lug plates, bucket lug sleeves, bucket teeth, tooth base, and guard plates or bucket corners. Its tooth base plate and side cutting plates are made of high-strength alloy plates, suitable for heavy-duty operating environments such as excavating hard soil mixed with relatively hard gravel, medium-hard rock, weathered rock or hard rock, and loading blasted ore. In heavy-duty operating scenarios, the bucket needs to be in long-term contact with hard materials such as ore, rock, and slag, enduring intense friction and compression; its wear resistance determines the service life of the equipment.

[0003] Currently, buckets used for heavy-duty operations typically have a single material of wear-resistant steel plate welded onto the bucket surface to improve wear resistance. However, during frequent impact operations, the wear-resistant layer fails at a faster rate, requiring frequent shutdowns for replacement, which seriously affects operational efficiency. Alternatively, in pursuit of structural strength, the thickness of the steel plate is excessively increased, resulting in an excessively heavy bucket that reduces the effective load of the equipment and indirectly affects operational efficiency.

[0004] Therefore, this utility model proposes a wear-resistant large bucket for heavy-duty operations to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant large bucket for heavy-duty operations, which solves the problem that existing technologies, in order to improve wear resistance, excessively increase the thickness of wear-resistant steel plates, resulting in excessive weight of the bucket itself and affecting operating efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A wear-resistant large bucket for heavy-duty operations includes a bucket body, wherein a reinforcing blade is connected to the edge of the bucket opening of the bucket body, and the reinforcing blade is detachably connected to the bucket body by high-strength bolts; a trunnion seat is provided on the back of the bucket body, and the trunnion seat is welded to the back of the bucket body. The inner sides of the bucket body are provided with multiple transverse and longitudinal reinforcing ribs. The transverse and longitudinal reinforcing ribs are perpendicularly intersecting and forming a grid structure. The intersections of the transverse and longitudinal reinforcing ribs are welded together. The inner sides of the bucket body are also provided with multiple transverse and longitudinal tie rods. The transverse tie rods are arranged longitudinally between the transverse reinforcing ribs, and the longitudinal tie rods are arranged transversely between the longitudinal reinforcing ribs. The transverse and longitudinal tie rods are perpendicularly intersecting and forming a grid structure. The intersections of the transverse and longitudinal tie rods are welded together. The intersections of the transverse and longitudinal reinforcing ribs are welded together, and the intersections of the longitudinal and transverse tie rods are welded together.

[0007] Furthermore, each side wall of the bucket body is provided with a riser, and a heating riser is welded into the riser.

[0008] Furthermore, reinforcing side plates are provided on the outer sides of both sides of the bucket body, and reinforcing ribs are connected between the reinforcing side plates and the side walls of the bucket body. The reinforcing ribs are evenly distributed along the length direction of the reinforcing side plates.

[0009] Furthermore, the inner wall of the bucket is provided with a plurality of wear-resistant strips arranged in parallel, the wear-resistant strips are arranged along the depth direction of the bucket, the cross section of the wear-resistant strips is trapezoidal, and the wear-resistant strips are provided with a guide slope near the bucket opening.

[0010] Furthermore, connecting seats are symmetrically welded to both sides of the back of the bucket body, and multiple bucket bottom support beams are connected in parallel between the connecting seats. The bucket bottom support beams are welded to the bucket body.

[0011] Furthermore, the reinforcing blade includes a blade body and a cemented carbide block embedded at the front end of the blade body. The cemented carbide block is evenly distributed along the length of the blade body, and the blade body has threaded holes that mate with high-strength bolts.

[0012] Furthermore, both ends of the trunnion seat are provided with grease channels, the grease channels extend axially along the trunnion seat and have oil outlet holes on their circumferential surfaces, and the end of the trunnion seat is provided with an oil inlet that communicates with the grease channels.

[0013] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows the reinforced blade at the edge of the bucket to first contact the material. The hard alloy block embedded at the front end of the blade directly withstands the impact and friction of the material due to its high hardness, preventing direct wear on the bucket body. Furthermore, the detachable design of the reinforced blade improves wear resistance without excessively increasing the overall thickness of the bucket, effectively controlling the bucket's weight and ensuring flexibility and efficiency during operation. Simultaneously, the transverse and longitudinal reinforcing ribs inside the side walls of the bucket form a grid structure through perpendicular intersections. These ribs also form secondary grids, with all intersections welded and fixed. This multi-level grid structure significantly enhances the sidewall's resistance to deformation. Combined with the outer reinforced side plates and evenly distributed reinforcing ribs along their length, this further strengthens the overall sidewall, ensuring the bucket's structural stability during heavy-duty operations.

[0014] The trapezoidal cross-section wear-resistant strips arranged along the depth direction on the inner wall of the hopper in this utility model not only enhance the wear resistance of the inner wall through structural reinforcement, but also guide the material smoothly into the hopper near the hopper opening, avoiding material accumulation and blockage at the hopper opening, reducing operation interruption time, and further improving loading efficiency.

[0018] like Figure 1-4 As shown, a wear-resistant large bucket for heavy-duty operations includes a bucket body 1. The edge of the bucket opening of the bucket body 1 is connected to a reinforcing blade, which is detachably connected to the bucket body 1 by a high-strength bolt 2. The reinforcing blade includes a blade body 3 and a carbide block 4 embedded in the front end of the blade body 3. The carbide block 4 is evenly arranged along the length of the blade body 3, and the blade body 3 has threaded holes that cooperate with the high-strength bolt 2.

[0019] Furthermore, a trunnion seat 5 is provided on the back of the bucket body 1, and the trunnion seat 5 is welded to the back of the bucket body 1; both ends of the trunnion seat 5 are provided with grease channels 6, the grease channels 6 extend axially along the trunnion seat 5 and have oil outlet holes on their circumferential surfaces, and the end of the trunnion seat 5 is provided with an oil inlet 7 that communicates with the grease channels 6.

[0020] Furthermore, multiple wear-resistant strips 8 are arranged parallel to each other on the inner wall of the bucket body 1. The wear-resistant strips 8 are arranged along the depth direction of the bucket body 1, and the cross-section of the wear-resistant strips 8 is trapezoidal. A guide slope is opened on the wear-resistant strips 8 near the bucket opening. Connecting seats 9 are symmetrically welded on both sides of the back of the bucket body 1. Multiple bucket bottom support beams 10 are connected in parallel between the connecting seats 9 and welded to the bucket body 1.

[0021] Furthermore, the inner sides of the bucket body 1 are provided with multiple transverse reinforcing ribs 11 and longitudinal reinforcing ribs 12. The transverse reinforcing ribs 11 and longitudinal reinforcing ribs 12 are perpendicularly intersecting and forming a grid structure, and the junctions of the transverse reinforcing ribs 11 and longitudinal reinforcing ribs 12 are welded together. The inner sides of the bucket body 1 are also provided with multiple transverse tie ribs 13 and longitudinal tie ribs 14. The transverse tie ribs 13 are arranged longitudinally between the transverse reinforcing ribs 11, and the longitudinal tie ribs 14 are arranged transversely between the longitudinal reinforcing ribs 12. The transverse tie ribs 13 and longitudinal tie ribs 14 are perpendicularly intersecting and forming a grid structure, and the junctions of the transverse tie ribs 13 and longitudinal tie ribs 14 are welded together. The junctions of the transverse reinforcing ribs 11 and longitudinal tie ribs 14 are welded together, and the junctions of the longitudinal reinforcing ribs 12 and transverse tie ribs 13 are welded together. Reinforcing side plates 15 are provided on the outer sides of both sides of the bucket body 1. Reinforcing ribs 16 are connected between the reinforcing side plates 15 and the side walls of the bucket body 1. The reinforcing ribs 16 are evenly distributed along the length of the reinforcing side plates 15. Each side wall of the bucket body 1 is provided with a riser 17, and a heating riser 18 is welded inside the riser 17.

[0022] The working process of this utility model is as follows: First, special grease is injected into the internal grease channel 6 through the oil inlet 7 at the end of the trunnion seat 5. The grease flows along the channel extending axially along the trunnion seat 5 and evenly penetrates into the mating gap between the trunnion and the trunnion seat 5 through the oil outlet hole on the circumferential surface, reducing frictional loss between the two during operation and avoiding increased wear of components due to insufficient lubrication. Furthermore, when the bucket is digging under heavy load, the reinforcing blade at the edge of the bucket mouth comes into contact with the material first. The hard alloy block 4 embedded at the front end of the blade 3 directly bears the impact and friction of the material due to its high hardness, avoiding direct wear on the bucket body 1. At the same time, since the reinforcing blade adopts a detachable design, the wear resistance can be improved without excessively increasing the overall thickness of the bucket body 1, effectively controlling the weight of the bucket itself and ensuring flexibility and efficiency during operation. During the excavation process, multiple wear-resistant strips 8 arranged in parallel on the inner wall of the bucket body 1 further enhance the wear resistance of the inner wall. Its trapezoidal cross-section structure can disperse the pressure of the material on the inner wall. At the same time, the guide slope near the bucket opening can guide the material to enter the bucket smoothly, reduce the accumulation and blockage of material at the bucket opening, and improve the loading efficiency. The symmetrically welded connecting seats 9 on both sides of the back of the bucket body 1, together with the parallel bucket bottom support beams 10, form a stable support structure. When the bucket bears the weight of heavy materials, the bucket bottom support beams 10 can distribute the pressure and prevent deformation of the bucket bottom due to concentrated stress. At the same time, the transverse reinforcing ribs 11 and longitudinal reinforcing ribs 12 inside the side walls of the bucket body 1 intersect perpendicularly to form a grid structure. The transverse tie ribs 13 and longitudinal tie ribs 14 also form a secondary grid, and all intersections are welded and fixed. The multi-level grid structure greatly improves the deformation resistance of the side walls. Combined with the outer reinforced side plates 15 and the reinforcing ribs 16 evenly arranged along their length, the overall strength of the side walls is further enhanced, ensuring the stability of the bucket structure during heavy-duty operations. The quality of the castings inside the bucket body 1 can also be checked through the risers 17 on the side walls of the bucket body 1. The heating risers 18 can reduce shrinkage defects inside the castings and ensure the structural strength of the bucket body 1.

[0023] After the operation is completed, check the wear of the carbide block 4 on the reinforcing blade. If there is severe local wear, the old reinforcing blade can be removed by disassembling the high-strength bolt 2, and a new reinforcing blade can be replaced and tightened again. There is no need to repair the bucket body 1, which reduces maintenance costs. At the same time, check the wear of the wear-resistant strip 8 on the inner wall of the bucket body 1. If the wear exceeds the threshold, a single wear-resistant strip 8 can be replaced to ensure the continuous wear-resistant protection effect of the inner wall.
