[0022] The hot gas generating device comprises a heating cylinder 13, a blower 14 is installed on the heating cylinder 13, the hot gas pipe 7 is connected with the heating cylinder 13, and the blower 14 blows air into the heating cylinder 13, and the heated air is blown into the first roller 2 through the hot gas pipe 7.

[0023] The heating cylinder 13 is electric heating or fuel heating, and the appropriate heating mode can be flexibly selected according to the vehicle condition.

[0024] The tail gas of the vehicle body 1 is connected with the heating cylinder 13 through a pipeline 15, and the tail gas of the vehicle body 1 is discharged into the heating cylinder 13 and then is blown into the first roller 2, so that the waste heat in the tail gas can be utilized, and the particles and impurities in the tail gas can be filtered by the accumulated snow, thereby reducing the pollution of the tail gas.

[0025] The outer wall of the first roller 2 is circumferentially provided with a plurality of axial protruding strips 16, and the through holes 6 are arranged in the gaps between the protruding strips 16, so that the melted snow water can not flow along the outer wall of the first roller 2 to the bottom, and thus the snow water can almost entirely flow into the first roller 2.

[0026] A plurality of axial air distribution pipes 17 are arranged in the first roller 2, and the air distribution pipes 17 are fixedly connected with the hot air pipe 7, the air distribution pipes 17 are always located at the top of the first roller 2, and the side wall of the air distribution pipe 17 is provided with upward air holes, so that the air can be uniformly blown to the upper part of the first roller 2.

[0027] A detachable annular baffle 18 is arranged at each end of the first roller 2, and the diameter of the baffle 18 is greater than the outer diameter of the first roller 2; in the initial accumulation stage of the snow layer, the baffle 18 is not arranged, so that the first roller 2 is pressed on the ground, when the snow layer outside the first roller 2 is accumulated to a certain thickness and is about to be melted from the inner layer, the baffle 18 is arranged, so that the overflow of the snow water from the end of the first roller 2 can be prevented, and the diameter of the snow layer is greater than the diameter of the baffle 18, so that the baffle 18 will not affect the snow removal.

[0028] The baffle 18 is made of two half circular rings, each of which is provided with a pin hole 19, two pins 20 are arranged at each end of the first roller 2 and can be inserted into the pin holes 19, and a compression nut 21 is arranged on the shaft diameter of each end of the first roller 2, when the baffle 18 is arranged, the two half circular rings are buckled on the shaft diameter of the end of the first roller 2, then the two pins 20 are inserted into the two pin holes 19 by being pushed inward, and finally the baffle 18 is compressed by tightening the compression nut 21.

[0029] A counterweight 22 is arranged on the rocker arm 4, so that the first roller 2 has enough pressure on the accumulated snow in the initial stage.

[0030] A hot air branch pipe 23 is arranged below the roller, the hot air branch pipe 23 is parallel to the first roller 2, a plurality of nozzles 24 are arranged on the hot air branch pipe 23 at intervals, the nozzles 24 are directed towards the ground and form an angle with the first roller 2, the hot air branch pipe 23 is connected with the hot air pipe 7 through a connecting pipe 25, and the connecting pipe 25 is provided with an on-off switch, when the temperature is low and the snow is dry and loose, the switch is opened, a part of the hot air reaches the hot air branch pipe 23 through the connecting pipe 25 and is blown out from the nozzles 24, so that a small part of the snow on the ground and the snow layer outside the first roller is melted, and the melted snow water seeps into the snow layer, thereby improving the adhesion of the snow layer when it is rolled.

[0031] When the snow is removed, the first roller 2 is pressed on the ground, and then the snow removal vehicle pushes the first roller 2 forward, the snow on the ground sticks to the first roller 2 and becomes larger and larger, when the thickness of the snow on the first roller 2 reaches a certain thickness, the snow removal vehicle is stopped, the baffle 18 is installed on both ends of the first roller 2, the hydraulic cylinder 5 is started to push the second roller 3 forward to press the snow layer outside the first roller 2, then the snow removal vehicle continues to move forward and the hot air generating device, the air blower 14 and the suction pump 11 are started, the high-temperature air starts to flow into the first roller 2 and blow out from the upper through hole 6 to melt the snow layer from the inside, the melted snow water flows into the first roller 2 through the through hole 6, and then is sucked into the shell 8 under the action of negative pressure and is pumped into the water collecting tank 12 by the suction pipe 10, after a part of the inner layer snow is melted, the snow on the first roller 2 is pressed inward under the action of self-weight and the pressure of the second roller 3, the increase speed of the snow on the outside and the melting speed of the inner layer snow are similar or the same, so that the thickness of the snow outside the first roller 2 reaches a dynamic balance, and the snow on the ground where the snow removal vehicle passes is cleaned.

[0032] After the snow removal is completed, the snow on the first roller 2 is continuously melted and removed.

[0033] The snow removal vehicle of the present application uses the principle of rolling snowball to remove snow, which is not only suitable for snow removal work on flat and hardened road surface, but also suitable for snow removal work on lawn, sand ground, pit and depression ground, rubber runway and other non-hardened, uneven and easily damaged ground surface, and can almost perform snow removal work on any ground surface without damaging the road surface; meanwhile, the snow is melted from the inner layer during snow removal, the snow water is collected, and the way of melting and collecting snow water from the inside can avoid overflow of snow water and re-icing.
