Roadheader

The utility model discloses a roadheader comprising a main body, a main guard plate disposed above the main body, the main guard plate facing towards the excavating direction of the roadheader. As the roadheader is needed to assist excavating on harder rock stratums, the main guard plate can block cracked rocks resulted from explosion, which prevents damage to the main body from collapsed rocks, thus increasing self-protective capability of the roadheader and reducing maintenance cost. The utility model also permits no far distance of the roadheader from the working spot upon explosion, thus saving round-trip fees and reducing operation cost of the roadheader.
