The windlass excavator integrated cutting, loading, transportation, drilling anchor, support, dust removal and other functions in one.Its structure is compact and the space utilization rate is high. The drilling and anchor mechanism is arranged above the walking part and moves to the front of the cutting head through the two-stage longitudinal moving mechanism for anchor protection, without affecting the normal tunneling operation.Dust duct is arranged on both sides of the frame to meet the requirements of roadway dust removal;The temporary support roof adopts the design of telescopic structure, and the support area is large.Compared with the conventional tunneling machine, the efficiency is 30%~50% higher, which is a new tunneling equipment integrating excavation, anchor and support.This machine is mainly suitable for coal and half coal tunnel construction.
