Digging mechanism plays an important role for onion harvester, which can affect the digging quality and efficiency of onion harvester. In this paper, the digging mechanism for onion harvester was studied and optimized based on finite element simulation technology. First, the parameters and shape of digging mechanism were researched and determined according to the work conditions. Further, the finite element simulating process of digging for above new-type of mechanism was performed. At last, the new-type of digging mechanism was analyzed and optimized based on finite element simulation technology. The studies show that the stress value of digging mechanism decreases, also the weight of digging mechanism reduces by 5.18%, which can cut short the cost of onion harvester and promote the advance speed effectively.
