Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to an externally mounted road construction cutting machine. Background Art

[0002] Construction cutting machines refer to cutting equipment used in the construction process, mainly used for cutting and processing various materials. Road construction cutting machines are mainly used for cutting concrete materials in road construction and maintenance. They are one of the important equipment in road construction, and the application of road construction cutting machines is becoming more and more extensive. Road construction cutting machines are mainly used to cut and crush concrete materials on old and damaged roads for repair and reconstruction. Road construction cutting machines are one of the important equipment that is indispensable in the road construction process. The development and application of their technology are of great significance to improving the quality of roads and construction efficiency. However, when existing road cutting machines encounter hard objects during road cutting, they are prone to being unable to quickly stop the cutting blade, resulting in damage to the blade, making the cutting machine unable to work, and resulting in low cutting efficiency. For this reason, we propose an external road construction cutting machine. Utility Model Content
