Dual-step snow sweeper

Abstract

A dual-step snow sweeper includes a body, on which a driving device, a self-propelled device, a snow sweeping device, and a handrail control device are arranged. The driving device drives the operation of the self-propelled device and the snow sweeping device, the snow sweeping device includes a snow scraping mechanism and a snow throwing mechanism, and the driving device includes at least one motor which is powered by a power supply device. The power supply device can use battery supply separately, and can supply power by being connected with alternating current through an AC-DC power supply system as well, or operate in such a way that the AC directly drives an AC motor.

         2 . The dual-step snow sweeper according to  claim 1 , wherein the motor uses a single motor or double motors, wherein when a single motor is used, one motor drives the operation of the self-propelled device and the snow sweeping device simultaneously, while when double motors are used, one motor drives the operation of the self-propelled device and the other motor drives the operation of the snow sweeping device. 
     
     
         3 . The dual-step snow sweeper according to  claim 1 , wherein the motor uses three motors, the first one of which drives the operation of the self-propelled device, the second one of which drives the operation of the snow scraping mechanism, and the third one of which drives the operation of the snow throwing mechanism. 
     
     
         4 . The dual-step snow sweeper according to  claim 2 , wherein when a single motor is used, the motor is a brushless motor, a magnetic steel motor, or a series-excited motor, and when more than two motors are used, the brushless motor, the magnetic steel motor and the series-excited motor are used simultaneously or the combination of any of the above motors is used. 
     
     
         5 . The dual-step snow sweeper according to  claim 1 , wherein the power supply device is a battery pack assembly or AC power supply, in which the battery pack assembly uses a single battery pack or the combination in series or in parallel of several battery packs of the same volume, the same voltage, or different volumes, different voltages. 
     
     
         6 . The dual-step snow sweeper according to  claim 1 , wherein the power supply device uses a hybrid power system formed by AC and DC. 
     
     
         7 . The dual-step snow sweeper according to  claim 6 , wherein the DC power supply directly drives the operation of the motor when the whole machine is connected with the DC power supply; the AC power supply drives the operation of the motor when the whole machine is connected with the AC power supply in the state that the DC power supply is connected or not connected. 
     
     
         8 . The dual-step snow sweeper according to  claim 1 , wherein the handrail control device comprises a plurality of sections of handrail, and the uppermost section of handrail is connected with a control panel. 
     
     
         9 . The dual-step snow sweeper according to  claim 1 , wherein the snow sweeping device comprises a snow throwing impeller, a snow scraper, and a snow sweeping decelerating mechanism, in which the snow throwing impeller is mounted on the input end of the snow sweeping decelerating mechanism, and the snow scraper is mounted on the output end of the snow sweeping decelerating mechanism. 
     
     
         10 . The dual-step snow sweeper according to  claim 1 , wherein the self-propelled device comprises a self-propelled decelerating mechanism which is provided with a clutch mechanism, the handrail control device is provided with a stay wire which is connected with the clutch mechanism, and the clutch mechanism is controlled by the stay wire. 
     
     
         11 . The dual-step snow sweeper according to  claim 3 , wherein when a single motor is used, the motor is a brushless motor, a magnetic steel motor, or a series-excited motor, and when more than two motors are used, the brushless motor, the magnetic steel motor and the series-excited motor are used simultaneously or the combination of any of the above motors is used.
