Description
Technical Field
[0001] This utility model relates to the field of disassembly and assembly technology of wear-resistant structure for loader buckets, and particularly to a wear-resistant structure for loader buckets that is easy to disassemble and assemble quickly. Background Technology
[0002] As a core piece of equipment in engineering construction, mining, and agricultural production, the loader's bucket is a crucial component that directly contacts materials and performs the loading and transporting actions. In actual operation, the front end of the bucket continuously withstands friction, impact, and compression from materials such as sand, ore, and soil, making it highly susceptible to wear and deformation. Therefore, wear-resistant shovel teeth must be installed on the front of the lower side wall of the bucket. These wear-resistant shovel teeth are typically made of high-strength wear-resistant steel. By covering the easily worn areas of the bucket, they extend the overall service life of the bucket, reduce equipment maintenance costs, and ensure the bucket's loading efficiency and operational stability. They are an indispensable wear-resistant protective structure for loader buckets.
[0003] Traditional loader bucket wear-resistant shovel teeth are typically installed using a "one-to-one individual fixing" design. This means each shovel tooth requires at least two bolts or pins to be individually connected and secured to the bucket. Since the shovel teeth wear and become damaged during use, they need to be replaced periodically. When replacing shovel teeth in batches, operators must disassemble the fixings for each tooth individually (e.g., loosen bolts, pull out pins), and after all the old teeth are removed, the new teeth are aligned and installed one by one, and the fixings are tightened again. This installation structure requires repeating a large number of identical disassembly and assembly actions, making batch tooth replacement extremely cumbersome and slow, significantly impacting the loader's overall operating time and project progress. Utility Model Content
[0004] The main objective of this invention is to provide a wear-resistant structure for loader buckets that is easy to assemble and disassemble quickly, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wear-resistant structure for a loader bucket that is easy to assemble and disassemble includes several wear-resistant shovel teeth. Each wear-resistant shovel tooth has a fitting groove at its rear end and a second storage groove at its upper end. Two second square holes are symmetrically formed on each wear-resistant shovel tooth, allowing it to pass through vertically. These holes also connect the second storage groove to the fitting groove. Several wear-resistant shovel teeth are fixedly installed on the front of the lower side wall of the bucket structure via a connecting fastener. The connecting fastener consists of a support plate, a connecting plate, and square rods. Several connecting plates are evenly fixedly installed laterally on the upper end of the support plate and inserted into the second storage groove. Several square rods are symmetrically fixedly installed in pairs on the lower ends of the connecting plates and inserted into both the second square holes and the bucket structure.
[0006] Preferably, the bucket structure is mounted on the loader body. The front part of the lower side wall of the bucket structure has a plurality of first square holes symmetrically arranged in pairs. The upper and lower ends of the lower side wall of the bucket structure have a plurality of connecting slots symmetrically arranged in pairs. The first square holes connect the two symmetrically arranged connecting slots. The upper end of the lower side wall of the bucket structure and behind the connecting slots have a first storage groove. The lower end of the lower side wall of the bucket structure has two threaded holes symmetrically arranged, and the threaded holes are connected to the first storage groove.
[0007] Preferably, the wear-resistant shovel teeth are fitted onto the front part of the lower side wall of the bucket structure through a fitting groove. The wear-resistant shovel teeth are simultaneously installed in two symmetrically opened connecting slots. The second square hole on the wear-resistant shovel teeth is aligned with the first square hole on the wear-resistant shovel teeth.
[0008] Preferably, the connecting plate on the connecting fastener is fixedly installed together with the support plate and the square rod by welding. Two bolt grooves are horizontally symmetrically opened on the support plate, and the bolt grooves pass through the support plate from top to bottom. The bolt grooves are coaxial with the threaded holes.
[0009] Preferably, the square rod on the connecting fastener is inserted into the second square hole and the first square hole, the support plate is embedded in the first receiving groove, and the support plate is fixedly connected to the bucket structure by bolts.
[0010] Compared with the prior art, the present invention has the following beneficial effects: By installing and fixing several wear-resistant shovel teeth onto the bucket structure through a connecting fastener consisting of a support plate, a connecting plate, and a square rod, it is not necessary to individually bolt or pin each wear-resistant shovel tooth to the bucket structure. When disassembling and assembling wear-resistant shovel teeth in batches, only the two bolts used to connect and fix the fastener to the bucket structure need to be removed and installed. Then, the square rod of the fastener is pulled out from the bucket structure and the wear-resistant shovel teeth, or the square rod of the fastener is inserted into the bucket structure and the wear-resistant shovel teeth. This completes the overall disassembly and assembly of all wear-resistant shovel teeth, greatly reducing repetitive disassembly and assembly actions, simplifying the operation steps, speeding up the batch replacement of wear-resistant shovel teeth, effectively shortening the downtime of the loader due to shovel tooth replacement, and ensuring the overall operating time of the loader and the progress of the project.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Please see Figure 1 - Figure 9 As shown, a wear-resistant structure for a loader bucket that is easy to assemble and disassemble includes several wear-resistant shovel teeth 1. A fitting groove 10 is provided at the rear end of each wear-resistant shovel tooth 1, and a second storage groove 11 is provided at the upper end of each wear-resistant shovel tooth 1. Two second square holes 12 are symmetrically provided on each wear-resistant shovel tooth 1, passing through it vertically. The second square holes 12 connect the second storage groove 11 to the fitting groove 10. Several wear-resistant shovel teeth 1 are fixedly installed on the front part of the lower side wall of the bucket structure 3 by a connecting fastener 2. The connecting fastener 2 consists of a support plate 13, a connecting plate 15, and square rods 9. Several connecting plates 15 are evenly fixedly installed laterally on the upper end of the support plate 13, and the connecting plates 15 are also inserted into the second storage grooves 11. Several square rods 9 are symmetrically fixedly installed in pairs on the lower ends of several connecting plates 15, and the square rods 9 are also inserted into the second square holes 11. Within the bucket structure 3, several wear-resistant shovel teeth 1 are fixed to the bucket structure 3 via a connecting fastener 2 consisting of a support plate 13, a connecting plate 15, and a square rod 9. This eliminates the need for individual bolt or pin fixing of each wear-resistant shovel tooth 1 to the bucket structure 3. When disassembling and assembling the wear-resistant shovel teeth 1 in batches, only two bolts used to connect and fix the fastener 2 to the bucket structure 3 need to be removed. Then, the square rod 9 of the fastener 2 is either pulled out of the bucket structure 3 and the several wear-resistant shovel teeth 1, or inserted into the bucket structure 3 and the several wear-resistant shovel teeth 1. This completes the overall disassembly and assembly of all wear-resistant shovel teeth 1, significantly reducing repetitive disassembly and assembly actions, simplifying operation steps, accelerating the batch replacement of wear-resistant shovel teeth 1, effectively shortening the downtime of the loader due to shovel tooth replacement, and ensuring the overall operating time and project progress of the loader.
[0015] Specifically, the bucket structure 3 is installed on the loader body 4. The lower side wall of the bucket structure 3 has several first square holes 6 symmetrically arranged in pairs at the front. The upper and lower ends of the lower side wall of the bucket structure 3 have several connecting slots 5 symmetrically arranged in pairs. The first square holes 6 connect the two symmetrically arranged connecting slots 5. The upper end of the lower side wall of the bucket structure 3, behind the connecting slots 5, has a first receiving groove 7. The lower end of the lower side wall of the bucket structure 3 has two symmetrically arranged threaded holes 8, which connect to the first receiving groove 7. Wear-resistant shovel teeth 1 are fitted onto the front of the lower side wall of the bucket structure 3 through a fitting groove 10. Simultaneously installed in two symmetrically arranged connecting slots 5, the second square hole 12 on the wear-resistant shovel tooth 1 is aligned with the first square hole 6 on the wear-resistant shovel tooth 1. The connecting plate 15 on the connecting fastener 2 is fixedly installed together with the support plate 13 and the square rod 9 by welding. Two horizontally symmetrical bolt slots 14 are opened on the support plate 13, which pass through the support plate 13 vertically. The bolt slots 14 are coaxial with the threaded hole 8. The square rod 9 on the connecting fastener 2 is inserted into the second square hole 12 and the first square hole 6. The support plate 13 is embedded in the first storage slot 7. The support plate 13 is fixedly connected to the bucket structure 3 by bolts. When the wear-resistant shovel tooth... When a batch of worn or damaged items needs replacement, first unscrew the two bolts that pass through the bolt slot 14 on the support plate 13 and connect to the threaded hole 8 on the bucket structure 3. Then, remove the connecting fastener 2 as a whole upwards, allowing several connecting plates 15 in the connecting fastener 2 to be pulled out from the second receiving slot 11 at the upper end of the wear-resistant shovel teeth 1. At the same time, allow several square rods 9, which are symmetrically fixed to the lower end of the connecting plates 15, to be pulled out from the second square hole 12 on the wear-resistant shovel teeth 1 and the first square hole 6 on the bucket structure 3. At this point, the fixation of the wear-resistant shovel teeth 1 is released. Then, remove the worn or damaged wear-resistant shovel teeth 1 from the bucket structure 3. Remove the new wear-resistant shovel tooth 1 from the connecting slot 5, then fit it onto the front of the lower side wall of the bucket structure 3 through the fitting slot 10 and install it into the connecting slot 5. Ensure that the second square hole 12 on the new wear-resistant shovel tooth 1 is aligned with the first square hole 6 on the bucket structure 3. Then, insert the square rod 9 of the connecting fastener 2 into the second square hole 12 and the first square hole 6 respectively, so that the connecting plate 15 is inserted into the second storage slot 11 and the support plate 13 is embedded into the first storage slot 7 opened on the bucket structure 3. Finally, pass the bolt through the bolt slot 14 on the support plate 13 and connect it to the threaded hole 8 on the bucket structure 3 and tighten it. At this time, the batch disassembly and replacement of the wear-resistant shovel tooth 1 is completed.
[0016] Furthermore, in actual operation, the bucket structure 3 installed on the loader body 4 is a key component that directly contacts materials such as sand, ore, and soil to complete the shoveling and transporting actions. The front of its lower side wall needs to continuously withstand the friction, impact, and compression of the materials. The wear-resistant shovel teeth 1, fitted into the front of the lower side wall of the bucket structure 3 via the mounting groove 10, are made of high-strength wear-resistant steel. This effectively covers the easily worn areas of the bucket structure 3, reducing direct wear, extending the overall service life of the bucket structure 3, lowering equipment maintenance costs, and simultaneously ensuring the shoveling efficiency of the bucket structure 3. Operational stability: The length and width of the square rod 9 are matched with the length and width of the first square hole 6 and the second square hole 12, respectively. This size matching design ensures that the square rod 9 can fit tightly against the hole wall when inserted into the first square hole 6 and the second square hole 12. This not only prevents the square rod 9 from shaking in the hole and ensures the stability of the connection fastener 2 in fixing the wear-resistant shovel teeth 1, but also prevents the wear-resistant shovel teeth 1 from being affected by loosening during operation. It also allows the square rod 9 to be smoothly inserted into or removed from the first square hole 6 and the second square hole 12, ensuring the convenience of batch disassembly and replacement of the wear-resistant shovel teeth 1.
[0017] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
