Description

Technical Field

[0001] The utility model relates to the technical field of road ice breaking, in particular to an ice breaking device which is convenient for step-by-step adjustment of the height of a rotary cutter. Background Art

[0002] As is known, icebreakers are mechanical equipment used to break ice on icy roads. They are mostly used in special areas and special occasions. For example, in areas that are relatively cold all year round, if the ice on the road is not broken in time, it cannot be naturally eliminated and will only accumulate thicker. For example, if the road surface of special places such as airports cannot be broken in time, it will affect traffic.

[0003] There are two types of ice-breaking devices used in existing ice-breaking vehicles. The first type is a roller-type ice-breaking blade with a horizontal rotating shaft, and the second type is a cutting-type horizontal rotary blade with a vertical rotating shaft. For example, the utility model with announcement number CN2547766Y adopts this method. Compared with the first type, it has a better ice-breaking effect, less damage to the road surface, and is more suitable for flat roads such as airports.

[0004] However, currently, when horizontal rotary knives are used, only one row is usually provided. This makes it more convenient to adjust the positioning according to the thickness of the broken ice, but is not conducive to further improving the ice-breaking effect. Utility Model Content
