Description

Technical Field

[0001] This utility model relates to the field of excavator technology, specifically to a plug-in bucket tooth structure. Background Technology

[0002] An excavator, also known as a digger, is an earthmoving machine that uses a bucket to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them at a stockpile. It is commonly used on construction sites. Since the excavator's digging function is achieved through its bucket, the bucket teeth are a crucial component, similar to human teeth, and are also wear parts. They are a combination of a tooth base and a tooth tip, connected by a pin. Because the tooth tip is the first part to contact the object's surface during excavator use, it experiences the most severe wear and requires frequent replacement. Current excavator bucket teeth have a complex structure, poor stability in the connection between the tooth tip and tooth base, and a complicated, time-consuming, and labor-intensive replacement process. Furthermore, the poor wear resistance of the bucket teeth reduces their service life and increases the cost of replacement. Utility Model Content

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0020] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A plug-in bucket tooth structure includes a bucket tooth body 1 and a tooth seat 2. A connecting component 3 for connecting with the tooth seat 2 is provided on the side of the bucket tooth body 1 near the tooth seat 2. A disassembly and assembly component 4 for disassembling and assembling the bucket tooth body 1 is provided on the side of the tooth seat 2 near the bucket tooth body 1. The connecting component 3 includes a connecting block 301 provided on the side of the bucket tooth body 1 near the tooth seat 2. One end of the connecting block 301 is fixedly connected to the outer wall of the bucket tooth body 1, and the other end of the connecting block 301 is fixedly connected to a plug-in housing 302. Both sides of the two plug-in housings 302 are penetrated by snap-fit ​​blocks 303. The disassembly and assembly component 4 includes a convex slot 401 opened on the side of the tooth seat 2 near the bucket tooth body 1. The connecting block 301 and the snap-fit ​​block 303 are inserted into the interior of the connecting block 301.

[0021] The outer walls of the two snap-fit ​​blocks 303 are slidably connected to the inner walls of the two side walls of the plug-in housing 302. The two snap-fit ​​blocks 303 are symmetrically arranged with the center line of the connecting block 301 as the axis of symmetry. The cross-sections of the two snap-fit ​​blocks 303 are trapezoidal. The two snap-fit ​​blocks 303 are snap-fit ​​connected to the convex slot 401. The end of each snap-fit ​​block 303 extending into the interior of the connecting block 301 is fixedly connected to a movable plate 304. The side walls of the two movable plates 304 are slidably connected to the inner wall of the connecting block 301. Guide rods 305 are provided on both sides of the inner cavity of the connecting block 301. When the snap-fit ​​block 303 moves to the appropriate position in the convex slot 401, under the action of the spring 306, the snap-fit ​​block 303 pops out and snaps into the inner wall of the convex slot 401, completing the quick connection between the bucket tooth body 1 and the tooth seat 2. The two ends of the two guide rods 305 pass through the two sides of the two movable plates 304 respectively, and are fixedly connected to the inner walls of the two sides of the connecting block 301. The inner walls of the two movable plates 304 are slidably connected to the surfaces of the two guide rods 305 respectively. Springs 306 are sleeved on the outside of the two guide rods 305. The two ends of the two movable plates 304 on opposite sides are provided with slots that are adapted to the springs 306. The two ends of the two springs 306 are connected to the two movable plates 304 through the slots. The inner cavity of the convex slot 401 is equipped with a double-threaded screw 402. The threads on both sides of the surface of the double-threaded screw 402 are reversed. A circular groove is opened on one side of the gear seat 2, and an internal hexagonal screw cap 5 is installed inside. One end of the double-threaded screw 402 is rotatably connected to the inner wall of the convex slot 401. Limiting sliders 406 are symmetrically opened at both ends of the inner wall of the convex slot 401 away from the main body of the tooth 1. The other end of the double-threaded screw 402 passes through the side wall of the gear seat 2 and is fixedly connected to the internal hexagonal screw cap 5. Movable blocks 403 are provided on both sides of the surface of the double-threaded screw 402. The inner walls of the two movable blocks 403 are respectively provided with... The internal threads on both sides of the surface of the double-threaded screw 402 are adapted to the internal threads of the two moving blocks 403. The inner walls of the two moving blocks 403 are threaded to the surface of the double-threaded screw 402. Each of the two moving blocks 403 is fixedly connected to a pressing plate 404. The rotation of the double-threaded screw 402 will drive the two moving blocks 403 to move closer to each other, thereby driving the pressing plate 404 to press the snap-fit ​​block 303, causing the snap-fit ​​block 303 to move into the insertion shell 302 until it is disengaged from the convex slot 401. At this time, the connecting block 301 and the insertion shell 302 can be pulled out from the convex slot 401 to complete the disassembly of the bucket tooth body 1. The two extrusion plates 404 are respectively in contact with the surfaces of the two snap-fit ​​blocks 303 on opposite sides. The side of the two moving blocks 403 away from the extrusion plates 404 is fixedly connected to the limiting groove 405. The end of the two limiting grooves 405 away from the moving blocks 403 extends into the interior of the two limiting sliders 406 and is slidably connected to the inner wall of the two limiting sliders 406.

[0022] In this process, the connecting block 301 and the plug-in housing 302 are inserted into the convex slot 401. The two snap-fit ​​blocks 303 are squeezed and move into the plug-in housing 302, and the spring 306 is compressed. When the snap-fit ​​block 303 moves to the appropriate position in the convex slot 401, under the rebound action of the spring 306, the snap-fit ​​block 303 pops out and snaps into the inner wall of the convex slot 401, thus completing the quick connection between the bucket tooth body 1 and the tooth seat 2.

[0023] The working process of this utility model is as follows: During use, the connecting block 301 and the insertion housing 302 are inserted into the convex slot 401. The two locking blocks 303 are pressed into the insertion housing 302, causing the spring 306 to compress. When the locking block 303 moves to a suitable position inside the convex slot 401, it pops out under the rebound action of the spring 306 and engages with the inner wall of the convex slot 401, completing the quick connection between the bucket tooth body 1 and the tooth seat 2. When it is necessary to disassemble the bucket tooth body 1, the internal hexagonal screw cap 5 can be rotated. The rotation of the double-threaded screw 402 causes the two moving blocks 403 to move closer to each other. This, in turn, causes the pressing plate 404 to press the snap-fit ​​block 303, which moves into the insertion housing 302 until it disengages from the convex slot 401. At this point, the connecting block 301 and the insertion housing 302 can be pulled out from the convex slot 401, completing the disassembly of the bucket tooth body 1. The entire disassembly and assembly process is simple and quick, greatly improving work efficiency.
