[0002] Anchor digger is a kind of mechanical equipment specially used for tunnel excavation and anchoring engineering. It is usually used in underground mining, tunnel construction, subway construction and other engineering projects. Anchor digger mainly consists of a car body, a rotating cutter disc, a tool system and a guide device. It uses the cutter head or tool on the rotating cutter disc to cut and crush the underground rock or soil, and uses the guide device to ensure the stability and accuracy of the excavation process. When operating, the anchor digger is usually equipped with a soil discharge conveyor belt to transport the cut rock or soil to the exit for processing. In addition, it may also be equipped with equipment such as anchor rods or steel cables to reinforce and support the structure inside the tunnel. When the front end of the anchor digger is working, it needs to be equipped with a cutting wheel box to carry out excavation work.
