Digging, anchoring and protecting all-in-one machine with rear-mounted anchoring and protecting mechanism

The invention discloses a digging, anchoring and protecting all-in-one machine with a rear-mounted anchoring and protecting mechanism. The machine comprises a machine body, a walking mechanism, a cutting mechanism, a temporary supporting mechanism and an anchor rod mechanism, the temporary supporting mechanism and the anchor rod mechanism are both arranged on an anchoring and protecting base, andtwo parallel sliding rails are arranged at the position, behind the cutting mechanism, of the top of the machine body in the longitudinal direction; and the lower portions of the two ends of the anchoring and protecting base are arranged on the sliding rails through sliding blocks, and a forward-extending oil cylinder driving the anchoring and protecting base to move along the sliding rails is fixed to the machine body. According to the digging, anchoring and protecting all-in-one machine, when the digging, anchoring and protecting all-in-one machine conducts cutting operation, the temporary supporting mechanism and t
