Description

A tunneling and anchoring integrated machine adaptable to tunnels of various heights Technical Field

[0001] This utility model relates to the field of coal mine roadway excavation technology, specifically to an integrated excavation and anchoring machine adaptable to roadways of various heights. Background Technology

[0002] With the gradual increase in the mechanization of coal mine roadway excavation, various types of roadheaders have gradually replaced blasting excavators. As a type of roadheader, the roadheader integrates functions such as coal cutting, coal transportation, and support, which can significantly improve the efficiency of roadway excavation and is now widely used in the coal industry.

Existing roadheaders and anchor bolters can generally only meet the requirements of a single roadway for excavation and support, and their adaptability to roadways of different heights is limited to only one or two components. To make the whole machine more adaptable to roadways of different heights, it is necessary to design multiple components specifically.

[0004] Based on the above, this utility model provides a roadway-anchoring integrated machine that is adaptable to roadways of various heights, thereby enhancing the adaptability of the integrated machine to roadways of different heights and improving equipment utilization.
