The invention belongs to the technical field of dust collection motor sweepers, and particularly relates to an electrically-driven multi-stage dust collection motor sweeper which comprises a sweeper body and a sweeping
assembly, a dust collection
assembly and a protection
assembly are arranged in the sweeper body, the sweeping assembly comprises a sweeping base, a sweeping roller, a driving wheel and a smashing roller, and the smashing roller is rotationally connected to the inner wall of the sweeping base in a sleeving mode. Garbage and sundries on the
road surface are rapidly gathered through the rotating sweeping roller, the sweeping roller synchronously drives the smashing roller and the
cutting cutter teeth to rotate at a high speed during operation, the garbage and sundries are smashed and
cut, and the
granularity of the sundries is effectively reduced; the
airflow sensor can sense
airflow changes and trigger the electric push rod, so that sealing of the
airflow pipe is relieved, high-speed airflow is formed according to the Bernoulli principle to
impact the outer walls of the cutter teeth, the positions of blocked sundries are changed, the
cutting cutter teeth are assisted to smoothly complete smashing operation, and the overall cleaning operation efficiency of the equipment is greatly improved.
