When the driving motor 703 is started, the rotating roller 7 rotates clockwise, and the evenly distributed digging teeth 701 on the rotating roller 7 drive the excavated stones to rotate clockwise and fall into the collecting hopper 3. Meanwhile, a receiving plate 301 is arranged below the rotating roller 7, which can receive the stones falling downward during the excavation of the digging teeth 701. The receiving plate 301 is arranged obliquely and inclined towards the collecting hopper 3, so that the stones fall accurately into the collecting hopper 3 through the extension plate 302.

[0047] Specifically, the side surface of the working platform 6 is provided with a ladder 601.

[0048] In use, the mechanical arm 2 connected to the front of the vehicle body 1 drives the collection bucket 3 to extend forward into the tunnel, bringing the rotating roller 7 into contact with the tunnel to be excavated. When the drive motor 703 is started, the rotating roller 7 rotates clockwise. The digging teeth 701 evenly distributed on the rotating roller 7 cause the excavated stones to rotate clockwise and fall into the collection bucket 3. At the same time, a receiving plate 301 is provided below the rotating roller 7. The receiving plate 301 can catch the stones and other materials falling downwards during the digging by the digging teeth 701. The receiving plate 301 is obliquely set and tilted into the collection bucket 3. The stones fall accurately into the collection bucket 3 along the receiving plate 301 and through the extension plate 302. At the same time, a cleaning plate 8 is provided behind the rotating roller 7. The cleaning plate 8 is located below the digging teeth 701, and multiple tooth openings 801 are opened at the positions corresponding to the digging teeth 701. At the same time, cleaning soft brushes extending inward are distributed on both sides of the tooth openings 801. When the digging teeth 701 rotate and pass through the tooth openings 801, the soft brush bristles extending inward can brush the excavated surface and clean the mud or stones adhering to the digging teeth 701. The working platform 6 is set on the top of the vehicle body 1, allowing employees to climb onto the working platform 6 to increase the height, which is convenient for installing high-altitude protection measures or carrying out operations. When the vehicle body 1 needs to move forward, the support legs 5 can be quickly retracted through the telescopic mechanism 504, and then retracted after moving forward.
