With the development of intelligent agricultural machinery,the existing agricultural machinery is upgraded in the direction of intelligence,mechanical shift is the bottleneck of the road to optimization.In order to solve this problem,this paper designs a kind of traditional gearbox electric shift mechanism,which is composed of electric push rod as the main actuating part,sensor as the detecting part and relay as the controlling part.Through the design of the executive part and the reliability test of the electric shift,it is proved that the electric shift mechanism can accomplish the free shift,which lays a foundation for the development of traditional machinery to intelligent direction and remote control.
