[0026] Referring to Figures 1-5A snow-cutting device includes snow-cutting wheels 2, two of which are symmetrically arranged in front of the front of a snowplow 1. Each snow-cutting wheel 2 includes a spindle 21, which is rotatably connected to the front of the snowplow 1. A side ring plate 22 is fixedly provided at one end of the spindle 21 in the snowplow 1. The side ring plate 22 serves as a baffle for the side of the snow-cutting wheel 2. A helical blade 23 is fixedly provided on the outer side of the spindle 21. The back of the helical blade 23 is provided with a blade helical reinforcing rib 28 along its length. The blade helical reinforcing rib 28 is formed by spinning angle steel and has the same pitch as the helical blade 23. The blade helical reinforcing rib 28 and the helical blade 23 are welded to form a closed structure. By spinning angle steel to form the blade helical reinforcing rib 28 and welding the helical blade 23 to form a closed structure, the back of the helical blade 23 is reinforced, which can effectively protect the helical blade 23 and prevent it from being damaged when encountering obstacles. The spiral blade 23 is fixedly connected to the spindle 21 by several support ribs 24. The support ribs 24 are closed structures, which are formed by welding multiple support plates. The cross-section is triangular. Specifically, they are formed by welding an L-shaped plate with a cross-section of 120 degrees and a flat plate. The top sealing plate 27 is welded to the end of the support rib 24. Through the closed structure of the support rib 24 and the top sealing plate 27 welded to the upper end of the support rib 24, the overall strength and rigidity of the snow cutting wheel are enhanced.

[0027] The outer periphery of the spiral blade 23 is provided with serrations 25 arranged in an array along its length. The serration design on the outer periphery of the spiral blade 23 is beneficial for cutting snow and ice blocks. The spiral blade 23 is fixed with snow-cutting barbs 26 arranged in an array along its length on the front side of the spiral propulsion. The snow-cutting barbs 26 are located on the outer edge of the spiral blade 23 and are inclined towards the spiral propulsion side. By adding snow-cutting barbs 26 to the spiral blade 23, when cutting snow, the snow-cutting barbs 26 can first contact the blown snow and cut the hard ice structure such as blown snow, effectively solving the problem of blown snow with a hardness close to that of ice.

[0028] The snow-cutting device of this invention is beneficial for cutting snow and ice blocks and can improve the strength of the snow-cutting device. On the one hand, it is not easily damaged when encountering icy roads such as blown snow. On the other hand, it can effectively solve the problem of blown snow during use, enabling snowplows to carry out snow-throwing operations efficiently. It is specially designed for snow-covered road sections with blown snow.

[0029] Specifically, in the manufacture, the angle steel is spun and the same pitch of the spiral blade 23 is formed into the blade spiral reinforcing rib 28, and then the blade spiral reinforcing rib 28 is welded on the tooling, the support rib 24 is the connecting part of the spiral blade 23 and the mandrel 21, and is positioned and welded on the tooling, and the support rib 23 is also a closed structure, there are four groups of support ribs 23, and the upper end of the support rib 23 is welded with the top sealing plate 27. In the installation, the snowplow 1 is symmetrically arranged on the left and right, forming a left snowplow and a right snowplow, and in the work, the two snowplows 2 cut the snow on the road surface to the middle and push to the snow throwing wheel of the snowplow 1, and then the subsequent snow throwing operation is performed.
