In the related art, the anchor drilling mechanism is generally arranged on the side surface of the main frame 100, because the anchor rods are required to be anchored in rows, after the anchor digger is cut, the anchor protection is required to be positioned in rows in a way of being withdrawn from the whole machine, the whole machine is withdrawn from the machine, the whole process is complicated, and the anchor drilling mechanism is required to be completed by a plurality of people in a matching way, and the anchor digger is time-consuming and labor-consuming, so that the tunneling efficiency of the anchor digger is greatly influenced. The tunnel roof is limited by the condition of the tunnel roof, and the empty roof distance is too small, so that the difficulty is higher when the anchor drilling mechanism is moved, and the difficulty of anchor protection work is further increased.
The all-in-one machine 1000 according to the embodiment of the present invention is provided at the upper end portion of the main frame 100 by the anchor drilling platform 200 such that the anchor drilling platform 200 is located at the upper end portion of the all-in-one machine 1000. The upper end space of the main frame 100 is large, and the anchor drilling platform 200 is not required to be disposed in the narrow spaces of the loading part 170 and the main frame 100. Thus, in the roadway with poor roadway side wall conditions, the situation that the components in the anchor drilling platform 200 are crushed by coal pile of the side wall is avoided, and the machine body of the tunneling and anchoring integrated machine 1000 is not easy to damage.
The anchor drill platform 200 is disposed at the upper end of the main frame 100, so that the anchor drill platform 200 can perform an anchor operation on the tunnel roof by using the structural height of the main frame 100 when performing the anchor operation.
