Description

Technical Field

[0001] The utility model belongs to the technical field of excavators, in particular to a novel excavator bucket structure. Background Art

[0002] An excavator, also known as a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the supporting surface and load them into transport vehicles or unload them to a stockpile. The bucket is a structural product and is a bucket-shaped component that is in direct contact with the soil. The cylinder uses high-pressure oil as a medium and connecting rods as auxiliary mechanisms to drive the bucket to perform excavation work.

[0003] During the foundation leveling process, a bucket with teeth may reduce the leveling accuracy. The teeth may leave marks or uneven areas on the foundation surface, especially in soft soil foundations or situations where high-precision leveling is required. If the operation is improper or the soil texture is soft, the teeth may penetrate too deeply into the foundation, causing local damage or cracks in the foundation. Therefore, we propose a new excavator bucket structure. Utility Model Content

[0004] The purpose of the utility model is to provide a new excavator bucket structure. By setting a scraper assembly and a flat plate design, it can fit closely to the ground and perform fine leveling operations on the foundation. The operator can accurately control the flatness and slope of the foundation to ensure that the foundation surface meets the smoothness and uniformity required by the design. This solves the existing problem that in soft soil foundations or situations requiring high-precision leveling, if the operation is improper or the soil texture is soft, the bucket teeth may penetrate too deeply into the foundation, causing local damage to the foundation or cracks.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a novel excavator bucket structure, comprising a bucket, wherein slide grooves are provided on the left and right sides of the bucket, the top of the bucket is fixedly connected to two connecting blocks, the top of the bucket is fixedly connected to a support base, and the side of the support base away from the bucket is fixedly connected to an oil cylinder. Although the oil cylinder may be subject to wear and damage in a complex working environment, it is relatively easy to maintain and replace the oil cylinder compared to other types of transmission components.

[0007] A scraper assembly is provided at the bottom of the bucket, and the scraper assembly includes a sliding frame slidably connected to the inner wall of the slide groove, the front of the sliding frame is fixedly connected to a flat plate, and the side of the sliding frame away from the flat plate is fixedly connected to a push rod. The bottom of the bucket is fixedly connected to two fixed slide rails. The design of the flat plate enables it to fit tightly to the ground and perform fine leveling operations on the foundation. The operator can accurately control the flatness and slope of the foundation to ensure that the foundation surface meets the design requirements of smoothness and uniformity.

[0008] Furthermore, the output end of the oil cylinder is fixedly connected to a push block, the end of the push block away from the oil cylinder is rotatably connected to a connecting rod 1, and the end of the connecting rod 1 away from the push block is rotatably connected to an arc rod, which can fit with the outer wall of the bucket and slide on the outer wall of the bucket through cooperation with the connecting rod 1.

[0009] Furthermore, a T-shaped slide rail is fixedly connected to the back of the bucket, and the outer surface of the T-shaped slide rail is slidably connected to the inner wall of the arc rod. The end of the arc rod away from the connecting rod one is rotatably connected to the connecting rod two. The T-shaped slide rail fits into the outer wall of the bucket, providing a stable moving trajectory for the arc rod, so that it maintains stable sliding.

[0010] Furthermore, the connecting rod 2 is rotatably connected to the outer surface of the push rod by one end of the push rod, and the front and back sides of the connecting rod 2 are fixedly connected with sliding rods, and the outer surfaces of the two sliding rods are slidably connected to the inner wall of the fixed slide rail. By setting the fixed slide rail, the push rod can move horizontally, thereby pushing the flat plate to slide stably.

[0011] Furthermore, a transverse groove is provided on the top of the bucket, and a disturbance assembly is provided inside the bucket, which includes two rotating blocks rotatably connected to the inner wall of the transverse groove through a rotating shaft, the bottoms of the two rotating blocks are fixedly connected to a rotating frame, the front and back sides of the two rotating blocks are fixedly connected to springs, and the ends of the two springs away from the rotating blocks are fixedly connected to the top of the bucket. The elastic force generated by the springs on both sides of the rotating blocks drives the rotating blocks to reset, thereby driving the rotating frame to disturb the residual soil inside the bucket, and then cooperates with the excavator driver to operate and control the bucket to shake, so as to clean the sticky soil inside the bucket.

[0012] Furthermore, the front of the bucket is fixedly connected to a pick plate, and the outer surface of the pick plate is slidably connected to a number of teeth, and a through hole is opened inside the several teeth, and the inner walls of several through holes are slidably connected to screws, and several screws slide through the pick plate, and the outer surfaces of several screws are threadedly connected to nuts. Use a wrench or other tool to twist the nut to remove it from the surface of the screw, and take the screw out of the through hole opened inside the tooth. At this time, the severely worn teeth can be detached from the outer surface of the pick plate, and then new teeth can be installed on the surface of the pick plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a scraper assembly, specifically a push rod that pushes the flat plate toward the position of the teeth through the sliding frame. When the flat plate moves to the front end of the teeth, the design of the flat plate enables it to fit closely to the ground and perform fine leveling operations on the foundation. The operator can accurately control the flatness and slope of the foundation to ensure that the foundation surface meets the design requirements of smoothness and uniformity.

[0015] 2. The utility model is provided with a disturbance component. Specifically, as the soil inside the bucket is poured out, residual soil will be assisted on the inner wall of the bucket. The elastic force generated by the springs on both sides of the rotating block drives the rotating block to reset, thereby driving the rotating frame to disturb the residual soil inside the bucket. The excavator driver then controls the bucket to shake and clean the sticky soil inside the bucket. The bucket can more effectively clean the residual soil in the bucket after each excavation, reducing the number of repeated excavations and improving work efficiency.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-5 As shown, the utility model is a novel excavator bucket structure, comprising a bucket 1, with chutes 101 provided on the left and right sides of the bucket 1, two connecting blocks 102 fixedly connected to the top of the bucket 1, a support base 103 fixedly connected to the top of the bucket 1, and a cylinder 104 fixedly connected to the side of the support base 103 away from the bucket 1;

[0027] A scraper assembly 2 is provided at the bottom of the bucket 1, and the scraper assembly 2 includes a sliding frame 202 slidably connected to the inner wall of the slide 101, the front of the sliding frame 202 is fixedly connected to the flat plate 201, and the side of the sliding frame 202 away from the flat plate 201 is fixedly connected to the push rod 203. The bottom of the bucket 1 is fixedly connected to two fixed slide rails 204, and a scraper assembly 2 is provided. Specifically, the push rod 203 pushes the flat plate 201 to move toward the position of the teeth 502 through the sliding frame 202. When the flat plate 201 moves to the front end position of the teeth 502, the design of the flat plate 201 enables it to fit closely to the ground, and perform fine leveling operations on the foundation. The operator can accurately control the flatness and slope of the foundation to ensure that the foundation surface meets the design requirements of smoothness and uniformity.

[0028] The output end of the oil cylinder 104 is fixedly connected to a push block 301 , the end of the push block 301 away from the oil cylinder 104 is rotatably connected to a connecting rod 1 302 , and the end of the connecting rod 1 302 away from the push block 301 is rotatably connected to an arc rod 303 .

[0029] The back of the bucket 1 is fixedly connected to a T-shaped slide rail 105 , the outer surface of the T-shaped slide rail 105 is slidably connected to the inner wall of the arc rod 303 , and the end of the arc rod 303 away from the connecting rod 1 302 is rotatably connected to the connecting rod 2 304 .

[0030] One end of the connecting rod 204 is rotatably connected to the outer surface of the push rod 203, and the front and back sides of the connecting rod 204 are fixedly connected to the sliding rod 305, and the outer surfaces of the two sliding rods 305 are slidably connected to the inner wall of the fixed slide rail 204.

[0031] The top of the bucket 1 is provided with a transverse groove, and the interior of the bucket 1 is provided with a disturbance component 4, which includes two rotating blocks 402 connected to the inner wall of the transverse groove by a rotating shaft. The bottom of the two rotating blocks 402 are fixedly connected to a rotating frame 401, and the front and back sides of the two rotating blocks 402 are fixedly connected to springs 403. The ends of the two springs 403 away from the rotating blocks 402 are fixedly connected to the top of the bucket 1. The disturbance component 4 is provided. Specifically, as the soil inside the bucket 1 is poured out, residual soil will adhere to the inner wall of the bucket 1. The elastic force generated by the springs 403 on both sides of the rotating block 402 drives the rotating block 402 to reset, thereby driving the rotating frame 401 to disturb the residual soil inside the bucket 1, and then cooperate with the excavator driver to operate and control the bucket to shake, so as to clean the sticky soil inside the bucket 1. The bucket can more effectively clean the residual soil in the bucket after each excavation, thereby reducing the number of repeated excavations and improving work efficiency.

[0032] A lifting plate 501 is fixedly connected to the front of the bucket 1, and a plurality of teeth 502 are slidably connected to the outer surface of the lifting plate 501, and through holes are formed inside the plurality of teeth 502.

[0033] The inner walls of the plurality of through holes are all slidably connected with screw rods 503 , the plurality of screw rods 503 are all slidably passed through the lifting plate 501 , and the outer surfaces of the plurality of screw rods 503 are all threadedly connected with nuts 504 .

[0034] A specific application of this embodiment is: when the bucket is in use, the bucket 1 is connected to the dipper arm of the excavator through the connecting block 102. When the excavator is digging and turning the soil, it will encounter hard rock and soil layers. When the bucket digs hard stones, the stones will cause wear on the teeth 502 at the end of the bucket 1. When the tip part of the teeth 502 is severely worn, the force required for the excavator to cut in during the excavation operation will be greatly increased, thereby increasing fuel consumption and reducing work efficiency. Use a wrench or other tool to twist the nut 504 to remove it from the surface of the screw 503, and remove the screw 503 from the through hole opened inside the tooth 502. At this time, the severely worn tooth 502 can be detached from the outer surface of the pick plate 501, and then a new tooth 502 is installed on the surface of the pick plate 501.

[0035] The work of the excavator is not only for excavating a large area of ​​earthwork, but also for leveling the ground during foundation excavation in house construction projects. The foundation excavation has a high requirement for flatness, so a scraper needs to be installed at the end of the bucket. The oil cylinder 104 is started to push the push block 301 downward. During the movement, the push block 301 pushes the arc rod 303 to slide on the surface of the T-shaped slide rail 105 through the connecting rod 1 302. As the arc rod 303 slides downward along the surface of the T-shaped slide rail 105, the arc rod 303 passes through the Connecting rod 203 304 pushes push rod 203 to move toward tooth 502. As push rod 203 moves, push rod 203 pushes plate 201 toward the position of tooth 502 through sliding frame 202. When plate 201 moves to the front end position of tooth 502, the design of plate 201 enables it to fit closely to the ground, performing fine leveling operations on the foundation. The operator can accurately control the flatness and slope of the foundation to ensure that the foundation surface meets the design requirements of smoothness and uniformity.

[0036] The elastic force generated by the springs 403 on both sides of the rotating block 402 drives the rotating block 402 to reset, thereby driving the rotating frame 401 to disturb the residual soil inside the bucket 1, and then cooperate with the excavator driver to control the bucket to shake, and clean the sticky soil inside the bucket 1. The bucket can more effectively clean the residual soil in the bucket after each excavation, reducing the number of repeated excavations and improving work efficiency.
