[0002] In many industries such as construction, mining, port, the loader plays a very important role, and its bucket tooth is directly in frequent contact with various materials and carries out digging, loading and unloading and other operations. In the long-term high-intensity use process, the bucket tooth faces extremely bad working environment, bears huge impact force, friction and the abrasion of materials, on the one hand, the frequent operation of the bucket tooth can lead to the gradual wear of its surface, the shape of the worn bucket tooth changes, and the cutting ability decreases, which not only reduces the working efficiency of the loader, but also increases the operating cost. For example, in the mining, the worn bucket tooth is difficult to effectively cut into the ore pile, and the loader needs to run at high power, thereby causing the fuel consumption to rise, and the operating cost to increase significantly, on the other hand, when the bucket tooth is subjected to strong impact force, it may be deformed, broken and seriously damaged. Once the bucket tooth is damaged, if it cannot be repaired or replaced in time, it will affect the normal use of the entire loader bucket, and even may cause safety accidents.
