When used as a mining machine for excavation operations, the bucket teeth of the bucket device will wear very quickly and are very easy to break. After being worn to a certain extent or broken, the entire bucket tooth component needs to be replaced as a whole, and the unworn part can only be treated as waste, which brings a very heavy cost burden to the excavator operator. If the bucket teeth are set to a split structure, this unnecessary loss will be greatly reduced, but the simple split structure will have the problem of unreliable connection relationship.

[0003] The invention patent application publication number CN114541509A discloses a split bucket tooth for an excavator bucket, which achieves the purpose of reducing costs by setting the bucket tooth as a split structure under wear conditions.

[0028] The technical effects of the utility model are:

[0029] 1. The utility model separates the existing integrated bucket teeth into the bucket teeth, conversion components and split locking components of the utility model by setting a conversion component of a specific structure in conjunction with a specifically set split locking component, so that the bucket teeth are separated under the premise of tight fit. When the lower part of the bucket teeth is worn, the bucket teeth can be directly replaced until they are worn to the position at the lower end of the conversion component. The conversion component is equivalent to the root of the original bucket teeth and does not need to be replaced. The worn or broken bucket teeth (equivalent to the tip of the bucket teeth in the prior art) can be replaced by removing the split locking component.

[0030] 2. The utility model sets a semi-lunar locking piece to cooperate with the tooth sleeve and fastening components of the specific structure, so that the tooth sleeve and the bucket tooth can achieve a tight fit, and because an arc-shaped gradually tightening fit is adopted, the arc portion is continuously pressed and extended between the main locking portion and the inner arc portion during the gradual tightening of the nut, so that the three form a very tight tight fit relationship, the fit clearance is always kept close to zero, and the elastic locking force is always maintained on the locking plate by setting the screw and the nut, so that a locking structure that does not produce relative displacement can be formed, so that it can withstand extreme multiple impacts (normal vibration of the bucket) without wear; therefore, compared with the existing bucket structure, the bucket tooth component set in the utility model is assembled with a tighter fit and a more resilient fit (not a rigid non-buffered fit), thereby greatly improving the service life of bucket teeth and other related components, while improving work efficiency, and at the same time reducing the probability of bucket tooth breakage to a certain extent.
