3) V-Bucket: The V bucket is a special excavator bucket. It has a V shaped structure that helps it penetrate easily through the soil. The angled sides make it easier to dig. This saves costs on power while digging. Work that involves laying pipes is ideally suited to this type of excavator bucket. 4) Skeleton Bucket: A skeleton bucket is a modified digging bucket. It accomplishes an additional task while digging.

Strength analysis of excavator bucket based on normal
In view of the phenomenon that the excavator bucket is damaged before it reaches the theoretical life in the actual normal digging process. Based on the continuous trajectory theory, the three-segment continuous trajectory excavated alternately by bucket and rod is selected as the normal digging trajectory. The theoretical digging force (TDF) and limiting digging force (LDF) on the normal
