【Abstract】 Some schemes that are used to improve the digging machine are introduced in this paper.The merits and faults and the feasibility of these schemes are compared.The scheme with three hydrodynamic shockers and three steel beams to improve the digging machine is discussed.This scheme can solve the problems that probably occur in the digging process.An example is introduced to explain how to determine the parameter of the hydrodynamic shocker.In this paper a new and effective scheme to improve the digging machine is presented.更多还原
