STABLE DIGGING TRAVEL DEVICE OF ONE WHEEL CONTROLLING MACHINE OF WALKING TYPE

PURPOSE:To stably drive the title device in a field with severe unevenness by setting another single drive wheel and a rotary digging tool side by side at the side of a driving wheel and a rotary digging tool and by connecting these driving wheels and the rotary digging tools by an upper driving wheel in a door type, respectively by making a long circuit. CONSTITUTION:Driving force of a motor 1 is transmitted to one wheel driving wheel 3 of a machine body 2 and a rotary digging tool 5 set at the end of the machine body 2. Driving force transmitted to the driving wheel 3 is reached through an upper driving shaft 7 to another driving wheel 4. Driving force transmitted to the rotary digging tool 5 is reached through an upper driving shaft 8 to another rotary digging tool 6. Consequently, two driving wheels 3 and 4 in the left and right directions can be stably traveled while carrying out digging operation by rotary digging tools 5 and 6 in left and right directions even in a field with severe unevenness.
