Structural Design And Analysis Of Four-legged Digging Robot

For a long time,Digging machines have been developed as forestry machines that can be used for afforestation under various conditions and can be used for fertilizing and digging pits.In addition,the digging machine can play a major role in various working conditions such as square construction,buried bar,and planting of fences.The digging machine is not only beautiful in appearance,but also has a powerful power source.Its operability is outstanding,and it is easy to operate and use,and it can reduce people's labor intensity,and its operation feel is more comfortable.Digging machine can not only reduce the workload of laborers,but also because it can adapt to a variety of different terrain,and the work efficiency is much higher than the manual efficiency.It is more convenient for outdoor work in the wild.At present,the digging machine is used in a variety of fields,and the frequency of digging machine is also increased suddenly.At the same time,the drawbacks of the existing digging machines are becoming increasingly obvious,including the degree of automation is too low and the all-terrain cannot be applied.This article will combine high automation and adapt to the development direction of various terrains,adopt four-legged robots as walking mechanism,and design and analyze suitable digging mechanism to meet the demand.At the same time,the fully automatic digging machine can further liberate the labor force and increase the operating space range,which greatly improves the operating efficiency and the reliability of the digging machine.The main core of this paper is the following two points:Mechanism Design Section:Digging machine designed to achieve vertical functions by determining the maximum diameter of the pit to be drilled,combined with the selected drill bit size and the functions to be achieved.The self-perpendicularity means that the designed digging robot can always keep the drill bit perpendicular to the ground by its own gravity according to different work environments in the climbing state.And through UG NX 8.0 the design and calculation of the appropriate drive,power source,gearbox,drill,etc.,and design a suitable four-legged walking mechanism to change the pit equipment to provide walking devices to meet the equipment to achieve fully automatic mode of operation.Modeling and analysis of the simulation part:based on UG NX 8.0 platform to complete the modeling of quadruped robots,static and dynamic simulation,and complete the gait planning of the institution.By using this software platform,relevant data can be obtained accurately,efficiently,and conveniently,and the reliability of the design scheme can be intuitively observed.
