The mounting bracket assembly 2 is provided with 4 power output shaft mounting holes 2-1, the aperture of the power output shaft mounting hole 2-1 is 60 mm, and the power output shaft mounting hole is used for fixing the power output shafts 1-6 and transmitting power required by high-speed rotation of the roller 1-2. The snow and ice loosening comb 7 is fixed to the front upper end of the mounting frame assembly 2 through bolts, is 3.0 meters long and made of hard nylon, and has the functions of loosening compacted snow and a solid ice layer on a road surface so as to improve the snow and ice removing efficiency of the scraper knife 1-2.
The utility model discloses a spiller combines work process of firm large-scale snow ice operation mechanism more: before the road snow ice removing operation, the thickness of an ice layer is measured to be 5 cm, the shovel blade height adjusting screw rod 5 is adjusted through the rotating hand wheel 6, so that the shovel blade of the shovel blade 1-1 moves downwards for 5 cm, namely the distance between the shovel blade and the road surface is close to 0 cm, and the distance between the shovel blade and a compacted snow ice layer is 5 cm. Because the compacted accumulated snow and the solid ice layer are relatively large in thickness, the roller 1-2 rotates at a low speed to keep the ice and snow old, namely the rotating speed of the roller is 360 r/min. The traveling speed of a traction locomotive of a large-scale snow and ice removing operation mechanism is 5-10 km/h, and under the cutting action of a scraper knife 1-1 rotating at a high speed, compacted snow and a solid ice layer on a road are crushed and separated from the road surface to be removed by a cleaning device. After the road compacted snow and solid ice layer clearing operation is completed, the power of the roller 1-2 is turned off, the roller 1-2 stops rotating at a high speed, and then the snow and ice removing operation mechanism assembly 1 is cleared, so that the next road compacted snow and solid ice layer clearing operation is required.
