[0002] In traditional coal mine tunnel excavation operations, the boring machine moves in and out frequently, the anchor drilling rig construction relies on manual drive, and the anchor support speed is slow, which takes up more than half of the excavation and anchoring time. There are problems such as low work efficiency, high labor intensity, and high risk. The excavator and anchoring machine is a large-scale coal mine machinery equipment that integrates cutting, coal dropping, transportation, travel, and anchoring. It is the core component for rapid coal mine excavation and mining.

[0033] An anchoring structure 18 connected to the vehicle body 2 .

[0034] When in use, the personnel drive the invention to move at the central console, and the crawler chassis walking assembly 1 drives the vehicle body 2 to move, so that the vehicle body 2 drives the cutting structure 3 to excavate in the tunnel. During this period, when it is necessary to install the mesh and steel sheets on the top of the excavated tunnel, the personnel standing on the vehicle body 2 take out the mesh and steel sheets from the storage box 17 and the steel sheet rack 16 respectively, and stack the mesh and steel sheets on the H-shaped support plate 12 and the fixing box 13, and then as the first active telescopic rod 14 extends into the mesh and engages with the edge of the steel sheet to limit the movement of the mesh and steel sheet, Afterwards, the first motor 8 drives the first active telescopic arm 9 to rotate, and the first active telescopic arm 9 is extended, and by unfolding the flip extension support 15, the flip extension support 15 provides auxiliary support for the mesh and steel sheet from below, at this time the motor frame 10 drives the first double-axis motor 11 to move toward the top of the tunnel, and the mesh and steel bars are supported by the H-shaped support plate 12 and contact the top of the tunnel, and then the anchor rod is installed on the anchor structure 18, so that the anchor structure 18 drills the anchor rod into the tunnel wall, so that the anchor rod restricts the movement of the steel bar, and the steel bar restricts the movement of the mesh.

A curved bar 40 is fixedly connected to the bottom of the control room 38, and the curved bar 40 is slidably connected to the connecting platform 30. The drive motor 37 drives the control room 38 to rotate through the transmission mechanism 36, so that the person in the control room 38 can rotate while sitting on the seat 39 and directly observe the drilling progress of the anchor without looking up.

[0039] In one aspect of this embodiment, the control console 35 is fixedly connected to a transparent protective cover 41. The transparent protective cover 41 is provided to prevent falling debris from directly falling onto the bodies of people in the control room 38, thereby protecting the safety of the people.

[0040] Example 2, based on Example 1, refer to Figure 3 and Figure 8 The flip extension support portion 15 includes a groove rail 45 fixedly connected to the H-shaped support plate 12.

The slider 44 is hinged to a flip bracket 46. The axial end of the flip bracket 46 is slidably connected to a guide frame 47 fixedly connected to the H-shaped support plate 12. The guide frame 47 is provided with a guide groove for guiding the flip bracket 46 to rotate. The guide groove is slidably connected to the axial end of the flip bracket 46. The third motor 42 drives the screw rod 43 to rotate. The screw rod 43 drives the slider 44 to slide along the groove rail 45. At the same time, the slider 44 drives the flip bracket 46 to move. During this period, the axial end of the flip bracket 46 is restricted by the guide groove in the guide frame 47, so that the flip bracket 46 rotates in the process of moving away from each other, so that the flip bracket 46 supports the mesh and the steel sheet.
