Description

Technical Field

[0001] This utility model relates to the field of excavator bucket teeth technology, specifically to an impact-resistant bucket tooth. Background Technology

[0002] Excavator bucket teeth are an important component of excavators, similar to human teeth. They are also wear parts, consisting of a tooth base and a tooth tip connected by a pin. Since the worn and failed part of the bucket teeth is the tooth tip, only the tooth tip needs to be replaced. However, when digging soil or other materials, existing bucket teeth often encounter hard materials such as rocks. The mounting base of the bucket teeth is prone to deformation when subjected to the impact of digging, causing the base connection to shake, which further affects the working efficiency of the excavator. Therefore, we propose an impact-resistant bucket tooth. Utility Model Content

[0003] The purpose of this invention is to provide an impact-resistant bucket tooth to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant bucket tooth, including a fixed base, with an installation groove and a first sliding groove respectively opened on the upper and lower sides of the middle part of the fixed base, a sliding ring slidably connected to the inner side of each installation groove, a spring circumferentially arranged on the inner side of each sliding ring, a pusher column fixedly connected to the front and rear sides of each sliding ring, the pusher column slidably connected to the inner side of the first sliding groove, a snap-fit ​​tooth fixedly connected to the right side of the fixed base, and teeth arranged on the right side of the snap-fit ​​tooth.

[0005] The tooth has a locking groove on its inner side, the locking tooth is inserted into the locking groove and connected to the tooth, and a second fixing bolt passes through the middle of the tooth.

[0006] The front and rear sides of the tooth are rotatably connected to cover plates, and the outer sides of the cover plates are rotatably connected to protective covers.

[0007] Each protective cover has an installation opening inside, and a telescopic rod is installed on the inside of each installation opening. The other end of the telescopic rod is fixedly connected to a fixing pin.

[0008] The fixing pin is slidably connected inside the mounting port and inserted into the side opening of the tooth.

[0009] The inner side of each mounting groove is threaded with a first fixing bolt.

[0010] This utility model has at least the following beneficial effects:

[0011] By creating corresponding openings inside the fixed base and installing structures such as sliding rings, springs, and push columns inside, when the fixed base is installed, the sliding rings on both sides are pushed when the first fixing bolt is retracted, thereby driving the push column to retract inward. When the first fixing bolt is tightened, the nuts and end caps on both sides of the first fixing bolt squeeze the sliding rings, thereby driving the push column to press against the mounting surface, improving the overall stability of the fixed base and avoiding the impact of the bucket digging on the fixed base. At the same time, a cover plate is set on the outside of the tooth mounting hole to prevent mud and other materials from clogging the outside of the second fixing bolt, making it difficult to remove and replace the tooth. The cover plate can be opened by opening the protective cover and pulling the fixing pin inward, making it easy to remove the second fixing bolt and replace the tooth. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 8 :

[0023] Example 1

[0024] This utility model provides a technical solution: an impact-resistant bucket tooth, comprising: a fixed base 1, with mounting grooves 12 and a first sliding groove 5 respectively opened on the upper and lower sides of the middle part of the fixed base 1, sliding rings 10 slidably connected to the inner side of the mounting grooves 12, and springs 9 arranged in a circumferential shape on the inner side of the sliding rings 10, and push columns 11 fixedly connected to the front and rear sides of the sliding rings 10, the push columns 11 slidably connected to the inner side of the first sliding groove 5, and a snap-fit ​​tooth 6 fixedly connected to the right side of the fixed base 1, with teeth 4 arranged on the right side of the snap-fit ​​tooth 6. When the fixed base 1 is installed, when the two ends of the first fixing bolt 2 are retracted, the sliding rings 10 on both sides are pushed, thereby driving the push columns 11 to retract inward. When the first fixing bolt 2 is locked, the nuts and end caps on both sides of the first fixing bolt 2 squeeze the sliding rings 10, thereby driving the push columns 11 to squeeze against the mounting surface, improving the overall stability of the fixed base 1.

[0025] The tooth 4 has a slot 7 on its inner side. The snap tooth 6 is inserted into the slot 7 and connected to the tooth 4. A second fixing bolt 8 passes through the middle of the tooth 4. The snap tooth 6 is connected to the slot 7 and is fastened by the second fixing bolt 8. This not only ensures the stable connection between the tooth 4 and the fixing seat 1, but also allows for quick disassembly and assembly, making it easy to replace the tooth 4.

[0026] Cover plates 3 are rotatably connected to both the front and rear sides of the tooth 4. Protective covers 13 are rotatably connected to the outer side of the cover plates 3. The cover plates 3 are used to block the mud and prevent the mud from blocking the connection between the second fixing bolt 8 and the tooth 4. The protective covers 13 are used to protect the telescopic rod 16 and ensure the normal insertion and removal of the telescopic rod 16.

[0027] Example 2

[0028] The protective cover 13 has an installation port 14 inside. The inner side of the installation port 14 is provided with a telescopic rod 16. The other end of the telescopic rod 16 is fixedly connected to a fixing pin 15. The fixing pin 15 is used to fix the buckle cover plate 3. When the fixing pin 15 is pushed and pulled, the telescopic rod 16 is used to push the fixing pin 15 to reset, so that the buckle can be fastened in a fixed position.

[0029] The fixing pin 15 is slidably connected inside the mounting port 14 and inserted into the side opening of the tooth 4.

[0030] The inner side of the mounting groove 12 is threaded with a first fixing bolt 2, which is used to install and fix the fixing seat 1 to ensure the stability of the fixing seat 1.
