Design and Experiment of Digging Spade Based on Bionic Golden Cicada
In order to solve the problems such as high digging resistance,poor soil breaking effect and poor viscosity reduction during sweet potato harvesting,a golden cicada bionic swwet potato digging shovel was designed.Through EDEM discrete element simulation analysis,dynamic simulation research was conducted on bionic excavator and ordinary excavator,and the results showed that at motion speeds of 0.6,0.8,and 1 m/s,the resistance experienced by the bionic excavator was significantly lower than that of the ordinary excavator.Compared with the digging resistance through field experiments,the average digging resistance of the bionic digging shovel is 5805.3N,and the average digging resistance of the ordinary digging shovel is 6298.4N.Compared with the ordi-nary digging shovel,the drag reduction effect of the bionic digging shovel is improved by 7.82％,which indicates that the bionic golden cicada sweet potato digging shovel has a good drag reduction effect,and to a certain extent,it has the effect of reducing the damage of sweet potatoes.
