when the blades 2 are unfolded, the heat-resistant cloth 6 is pulled, the distance between the heat-resistant cloth 6 and the blades 2 is reduced, the first magnetic block 7 and the second magnetic block 8 are adsorbed together, when the blades 2 are folded, the heat-resistant cloth 6 is wound on the folding and unfolding rod 5 again, at the moment, relative sliding is generated between the heat-resistant cloth 6 and the blades 2, the first magnetic block 7 is pulled out from the mounting groove 9 by the second magnetic block 8, when the second magnetic block 8 is separated from the first magnetic block 7, the elastic block 10 drives the first magnetic block 7 to float up and down, the first magnetic block 7 impacts the heat-resistant cloth 6, the shaking degree of the heat-resistant cloth 6 is further improved, so that snowflakes or other sundries falling from the heat-resistant cloth 6 are shaken down, and the self-cleaning of the heat-resistant cloth 6 is completed; when the snow blower works, snow at the position right below the spraying cylinder 1 and the blades 2 cannot be blown, at the moment, airflow in the spraying cylinder 1 is guided to the position right below the spraying cylinder 1 through the flow deflector 12, the sleeve 11 and the L-shaped pipe 13, the L-shaped pipe 13 is controlled to slide in the sleeve 11 through the second air cylinder 14, the ground clearance of the L-shaped pipe 13 is adjusted, the L-shaped pipe 13 can be blown to be attached to the ground, the snow at the position is blown off, the problem of a snow removing dead angle is avoided, and therefore snow removing efficiency is improved; when the air flow passes through the L-shaped pipe 13, the auger 16 is pushed to rotate, and then the auger 16 drives the elastic strips 17 to rotate through the rotating shaft 15, so that the elastic strips 17 can hit the road surface below the auger and stir the accumulated snow at the position to be crushed, and the crushed accumulated snow is blown away by the air flow, and the operation can avoid the problem that the accumulated snow is difficult to blow off due to the fact that the accumulated snow density is increased and is adhered to the ground after the accumulated snow at the position is rolled by the front wheels of the snow blowing vehicle; by arranging the stripping block 18, when the free end of the elastic strip 17 is in contact with the ground, the snow cover at the free end can be shoveled down by the stripping block 18, so that the stripping block 18 is separated from the ground, the snow cover is blown away by airflow after being thrown by the stripping block 18, and the snow cover is further blown off after being rolled, and meanwhile, the stripping block 18 is made of a flexible material, so that the situation that the road surface is damaged by the stripping block 18 can be avoided; when the elastic strip 17 drives the stripping block 18 to contact the ground, the elastic strip 17 receives the reaction force of the ground to the tip of the stripping block 18, so that the included angle between the stripping block 18 and the elastic strip 17 is increased, the elastic sheet 21 pulls the elastic membrane 20 to be close to the elastic strip 17, the cavity of the pressure cavity 19 close to the return spring 22 and the guide hole 23 form negative pressure, so that suction force is generated between the tip of the stripping block 18 and the ground, the rebound amplitude can be reduced after the stripping block 18 impacts the ground, the stripping block is quickly attached to the ground, and the snow shoveling area of the stripping block 18 to the ground is increased; the elastic cloth 24 can prevent snow and other impurities shoveled on the upper side of the stripping block 18 from entering the pressure cavity 19 to cause blockage of the pressure cavity 19, and meanwhile, the elastic piece 21 and the stripping block 18 can drive the elastic cloth 24 to shake when moving relatively, so that accumulated snow remained on the outer side of the elastic cloth 24 in the previous wheel can be shaken off, and snow shoveling can be conveniently carried out in the next wheel; when the elastic sheet 21 pulls the elastic membrane 20 to move, the first magnet 25 is close to the second magnet 26 and pushes the elastic cloth 24 to bulge outwards, so that accumulated snow on the elastic cloth 24 is shaken off, the self-cleaning of the stripping block 18 is completed, and the problem of reduction of snow shoveling amount of the stripping block 18 is avoided.
