Hybrid driving snow sweeper

Abstract

A hybrid driving snow sweeper includes a snow sweeping impeller. The snow sweeping impeller is mounted on an impeller shaft. The impeller shaft is driven by a motor. The motor includes a DC motor and an AC motor. The DC motor and the AC motor are connected with a control panel. The control panel is connected with wires of battery power supply and AC power supply. The control panel controls the operation of the DC motor or the AC motor so as to drive the impeller shaft. The DC motor and the AC motor are set simultaneously.
