Abstract

The utility model discloses an improved driving device of an automatic dust collector. The improved driving device is composed of two driving wheel sets and a driven wheel set, the driving wheel sets drive planetary gear sets through worms and therefore drive rear driving wheels through output shafts, the worms of the driving wheel sets are meshed with the planetary gear sets, power of each driving wheel set is transmitted to the corresponding planetary gear set in each tooth point making contact with the tooth flanks of the corresponding driving wheel set and the corresponding planetary gear set in a low-friction and evenly decelerated mode, further deceleration is conducted by means of the interior structure of each planetary gear set, and noise produced by the driving wheel sets in work is effectively restrained. In addition, while the driving wheel sets of the improved driving device provide forward moving power of the automatic dust collector, the driven wheel set of the improved driving device can freely rotate 360 degrees; when the automatic dust collector encounters obstacles or a rugged surface, the driven wheel set of the improved driving device rotates freely, and the automatic dust collector turns by being pushed by the driving wheel sets.
