Motor sweeper dust colleting device

The invention relates to a motor sweeper dust collecting device. The motor sweeper dust collecting device is provided with a filtering system frame assembly, a vibration motor and a filtering net set. The vibration motor is fixedly arranged on the filtering system frame assembly. The filtering net set is arranged in the filtering system frame assembly and located at an inlet of the filtering system frame assembly. The motor sweeper dust collecting device is characterized in that the filtering net set sequentially comprises a first filtering net and a second filtering net in the air flowing direction, a filtering net support is arranged at an inlet of the filtering system frame assembly, the first filtering net is arranged on the filtering net support, and the filtering net support is evenly provided an air inlets. The motor sweeper dust collecting device is simple in structure, easy to detach and wash and capable of effectively preventing the filtering nets from being blocked, the dust collecting effect is greatly improved, and secondary pollution to the vehicle body is effectively avoided.
