Multifunctional and portable shaft-free screw conveying type snow suction machine as well as sweeping and conveying method

The invention discloses a multifunctional and portable shaft-free screw conveying type snow suction machine as well as a sweeping and conveying method. Accumulated snow is required to be loaded manually, which is time-consuming, labor-consuming and low in efficiency; soft accumulated snow has large volume and light mass and occupies limited transport space of transport vehicles in the transportation process, and the volume of vehicles is low. The snow suction machine comprises a power system (17), a conveying system (18) and a support system (19), wherein the conveying system comprises a screwconveyer (11), one end of the screw conveyer is connected with a large belt pulley axle (16) of the power system through a U-shaped pin (10), the other end of the screw conveyer is connected with a support (20) of the support system through a deep groove ball bearing, the screw conveyer is sleeved with a hose (5), one end of the hose is fixedly connected with the power system, and the other end of the hose is fixedly con
