However, the existing structure of the tunneling and anchoring integrated machine has the problem that the distance from the front row of anchor rod drilling machines to the head-on position is more than 3 meters, namely, the tunneling head always has an empty top of more than 3 meters. However, once the roof conditions are slightly broken, the jumbolter arranged on the tunneling and anchoring integrated machine cannot be used, and the shoveling operation can be carried out only by manually holding the drilling machine to the position of the tunneling head in the empty roof state, so that the tunneling efficiency cannot be kept up, and the passive manual shoveling operation is more dangerous than the manual shoveling operation carried out by using a common tunneling machine. Therefore, the tunneling efficiency of the tunneling and anchoring integrated machine is high, but the applicable conditions are limited, and the tunneling and anchoring integrated machine is only suitable for being used in a tunneling roadway with a complete top plate. Therefore, the improvement of the airborne drilling and anchoring device of the existing tunneling equipment is needed.
