Description

Technical Field

[0001] This utility model relates to the field of excavators, and in particular to a corrosion-resistant wetland excavator bucket. Background Technology

[0002] Excavators, as engineering machinery for digging, loading, and transporting materials, rely on hydraulic systems to drive the operation of various components and are widely used in construction, mining, and other fields. In wetland environments, the large amount of water, silt, and unstable pH levels make ordinary buckets highly susceptible to corrosion, affecting their service life and increasing maintenance and replacement costs. In contrast, corrosion-resistant wetland excavator buckets use special materials and surface treatment processes to effectively resist wetland erosion, reduce corrosion, ensure the bucket maintains good digging and loading performance, improve work efficiency, and reduce downtime. In addition, their longer service life reduces the frequency of bucket replacement and maintenance workload, thereby reducing the overall operating costs of the equipment.

[0003] Existing corrosion-resistant wetland excavator buckets operate by leveraging multiple principles, including materials, structural design, and surface treatment. In terms of material selection, corrosion-resistant materials such as stainless steel are used, or ordinary steel is treated with a ceramic coating to isolate corrosive media. In terms of structural design, streamlined shapes and drainage holes are adopted to reduce material residue and water immersion, and easily corroded parts are reinforced. In the surface treatment stage, passivation and phosphating are used to generate a dense protective film. These multiple measures improve the bucket's corrosion resistance and working efficiency.

[0004] In practical applications, although the buckets of corrosion-resistant wetland excavators effectively cope with the corrosion challenges of wetland environments thanks to their excellent materials and structural design, there are still significant shortcomings in the bucket tooth replacement process during equipment use. As a key and vulnerable component of the bucket, the bucket teeth wear out extremely frequently during excavation operations. However, the current bucket tooth replacement mechanism is extremely complex. Maintenance personnel often need to use a variety of specialized tools to perform tedious disassembly operations in order to remove the bucket teeth from the bucket. This not only consumes a lot of time and manpower, seriously affecting the normal operation of the equipment, but also greatly reduces the operational efficiency of the corrosion-resistant wetland excavator buckets, thereby delaying the progress of the entire project. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a corrosion-resistant wetland excavator bucket, which aims to improve the problem of requiring complicated operations to remove and replace the bucket teeth during equipment use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion-resistant wetland excavator bucket, comprising a bucket, a plurality of connecting teeth fixedly connected to the bottom of the bucket, a plurality of fixing components being provided inside each connecting tooth, bucket teeth being slidably connected to the outer wall of each connecting tooth, and a plurality of connecting plates fixedly connected to the top of the bucket, with connecting components provided between the connecting plates;

[0007] Each of the fixing components includes a fixing pin, a limiting plate, and a spring. The outer wall of each fixing pin is slidably connected to the inside of the connecting teeth. The inner wall of each limiting plate is fixedly connected to the outer wall of the fixing pin. Each spring is disposed inside the connecting teeth. One end of each spring is fixedly connected to the inside of the connecting teeth, and the other end of each spring is fixedly connected to one side of the limiting plate.

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

[0009] The connecting assembly includes multiple connecting pins and multiple fixing blocks. Each connecting pin passes through the connecting plates, and each fixing block is fixedly connected to the outer wall of the connecting pin.

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

[0011] The fixing blocks are fixedly connected by fixing rods, the top of the fixing rods is fixedly connected to a connecting arm, and one side of the connecting arm is fixedly connected to multiple connecting rods.

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

[0013] A fixing column is fixedly connected between the connecting rods, a connecting pipe is fixedly connected to the top of the fixing column, and a fixing plate is fixedly connected to the bottom of the fixing column.

[0014] As a further description of the above technical solution:

[0015] The fixed plate has a sliding rod slidably connected inside, and multiple sliding columns are fixedly connected to the outer wall of the sliding rod.

[0016] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The bottom of the fixed plate is rotatably connected to a turntable, and multiple fixing slots are opened on one side of the turntable. A nozzle is fixedly connected to the bottom of the turntable.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the fixing pin is first pressed down to retract into the connecting tooth, unlocking the damaged bucket tooth. Then, the bucket tooth is grasped and pulled outward to remove it. After that, the new bucket tooth is taken out and fitted onto the outer wall of the connecting tooth, so that the fixing pin is squeezed into the connecting tooth. When the bucket tooth is installed in place, the fixing pin pops out under the action of the spring to fix the bucket tooth. This achieves the effect of easily removing and replacing the bucket tooth during equipment use, avoiding the problem of needing complicated operations to remove and replace the bucket tooth during equipment use, thereby improving the efficiency of the corrosion-resistant wetland excavator bucket.

[0024] 2. In this utility model, first hold the pull ring and pull it outward to disengage the moving column from the fixed groove, unlock the turntable, then hold the nozzle and rotate it to the desired angle, and then push the connecting block again to make the moving column slide back into the fixed groove to fix the nozzle angle.

[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 1-3 An embodiment of this utility model is provided: a corrosion-resistant wetland excavator bucket, including a bucket 1, a plurality of connecting teeth 2 are fixedly connected to the bottom of the bucket 1 for connecting bucket teeth 6, a plurality of fixing components are provided inside each connecting tooth 2 for fixing the bucket teeth 6, and a bucket teeth 6 are slidably connected to the outer wall of each connecting tooth 2 for digging the soil, and a plurality of connecting plates 7 are fixedly connected to the top of the bucket 1 for connecting fixing rods 10, and connecting components are provided between the connecting plates 7;

[0034] Each fixing component includes a fixing pin 3, a limiting plate 4, and a spring 5. The outer wall of each fixing pin 3 is slidably connected to the inside of the connecting tooth 2 to fix the bucket tooth 6. The inner wall of each limiting plate 4 is fixedly connected to the outer wall of the fixing pin 3 to limit the movement range of the fixing pin 3. Each spring 5 is disposed inside the connecting tooth 2 to provide elastic force to the fixing pin 3. One end of each spring 5 is fixedly connected to the inside of the connecting tooth 2, and the other end of each spring 5 is fixedly connected to one side of the limiting plate 4. The connecting component includes multiple connecting pins 8 and multiple fixing blocks 9. Each connecting pin 8 passes through the connecting plates 7 to connect two fixing blocks 9. Each fixing block 9 is fixedly connected to the outer wall of the connecting pin 8 to align with the connecting plate 7.

[0035] Specifically, when the excavator is operating in wetlands, the bucket teeth 6 are in direct contact with hard media such as mud, sand, and gravel for extended periods, inevitably causing damage to their surface. In such cases, timely replacement is necessary. The maintenance personnel first press the retaining pin 3. Under this operation, the retaining pin 3 slowly retracts into the connecting tooth 2, successfully unlocking the damaged bucket tooth 6. Then, the maintenance personnel hold the bucket tooth 6 and pull it outwards with even force, successfully completing the disassembly of the damaged bucket tooth 6. Next, the maintenance personnel take out a brand-new bucket tooth 6 and precisely fit it onto the outer wall of the connecting tooth 2. During the fitting process, the inner wall of the bucket tooth 6 compresses the retaining pin 3, causing the retaining pin 3 to retract into the connecting tooth 2 again. Once the bucket tooth 6 is in place, the retaining pin 3 quickly pops out under the strong elastic force of the spring 5, firmly securing the bucket tooth 6. Thus, the replacement of the bucket tooth 6 is successfully completed.

[0036] Reference Figure 4 and Figure 5 A fixing rod 10 is fixedly connected between the fixing blocks 9 to connect the bucket 1. A connecting arm 11 is fixedly connected to the top of the fixing rod 10 to connect the fixing rod 10. Multiple connecting rods 12 are fixedly connected to one side of the connecting arm 11 to connect the fixing column 13. A fixing column 13 is fixedly connected between the connecting rods 12 to fix the nozzle 24. A connecting pipe 14 is fixedly connected to the top of the fixing column 13 to connect the water pipe. A fixing plate 15 is fixedly connected to the bottom of the fixing column 13 to connect the turntable 22. A sliding rod 16 is slidably connected inside the fixing plate 15 to connect with the connecting block 18. Multiple sliding rods 16 are fixedly connected to the outer wall of the sliding rod 16. A sliding column 17 limits the movement range of the sliding rod 16. A connecting block 18 is fixedly connected to one end of the sliding rod 16 for connecting the moving column 21. A rotating column 19 is fixedly connected to one side of the connecting block 18 for connecting the pull ring 20. The pull ring 20 is rotatably connected inside the rotating column 19 for pulling the connecting block 18. A moving column 21 is fixedly connected to one side of the connecting block 18 for fixing the angle of the turntable 22. A turntable 22 is rotatably connected to the bottom of the fixing plate 15 for rotating the nozzle 24. Multiple fixing slots 23 are opened on one side of the turntable 22 for accommodating the moving column 21. A nozzle 24 is fixedly connected to the bottom of the turntable 22 for spraying clean water.

[0037] Specifically, when the angle of the nozzle 24 needs to be adjusted, the staff first locates the pull ring 20, firmly grasps it, and pulls it outward with even force. During this process, the pull ring 20 drives the moving column 21 to overcome the friction of the fixing groove 23 and slowly disengage from the fixing groove 23. This action successfully unlocks the turntable 22. After unlocking, the staff holds the nozzle 24 with both hands and slowly rotates the nozzle 24 to the appropriate angle according to the actual needs. After the angle adjustment is completed, the staff pushes the connecting block 18. The connecting block 18 drives the moving column 21 to slide back into the fixing groove 23 along its track. As the moving column 21 slides completely into the fixing groove 23, the angle of the nozzle 24 is firmly fixed, and the entire nozzle 24 angle adjustment is successfully completed.

[0038] Working principle: When the bucket tooth 6 is damaged and needs to be replaced during the use of the corrosion-resistant wetland excavator bucket, first press the fixing pin 3 to retract it into the connecting tooth 2, unlock the damaged bucket tooth 6, then hold the bucket tooth 6 and pull it out to remove it. After that, take out the new bucket tooth 6 and put it on the outer wall of the connecting tooth 2, so that the fixing pin 3 is squeezed into the connecting tooth 2. After the bucket tooth 6 is installed in place, the fixing pin 3 pops out under the action of the spring 5 to fix the bucket tooth 6, thus completing the replacement of the bucket tooth 6. When it is necessary to clean the bucket 1, first connect the water pipe to the connecting pipe 14, then adjust the angle of the nozzle 24. First, hold the pull ring 20 and pull it outward to make the moving column 21 disengage from the fixed groove 23. Unlock the turntable 22, then hold the nozzle 24 and rotate it to the required angle. Then push the connecting block 18 again to make the moving column 21 slide back into the fixed groove 23 to fix the angle of the nozzle 24. Then connect the water source to start cleaning the bucket 1 with clean water.

[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. 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.
