And realize automatically linearly walking.When irrigation sprinkler start working as determined by rectilinear direction travel with uniform speed slow time, if not
Rectilinear direction determined by deviation, then steering spindle 17 does not produce the skew in angle, i.e. direction offset sensor 19 and does not produce partially
Shifting signal, the most whole control system need not regulation, and irrigation sprinkler continues linearly to travel.If because certain reason irrigation sprinkler deviates
During predetermined traveling straight line, necessarily there is the skew in angle in front driving wheel steering spindle 17, such Programmable Logic Controller 14 can basis
Offset direction signal that direction offset sensor 19 is received and the high low signal of side-play amount, notice motor 16 rotates to be adjusted
The position of whole driving wheel so that it is return on original linear position, may finally make irrigation sprinkler the most linearly walk.This practicality is new
