[0005] The operation of the bolter assembly of the present invention includes:

[0006] 1.

The telescopic inner sleeve is inserted into the telescopic outer sleeve, and the hexagonal telescopic inner (outer) sleeve is connected with a pin through a telescopic oil cylinder, and the telescopic inner sleeve is driven to telescopically operate through the telescopic oil cylinder.

[0008] 3. No blind spots during operation: By swinging the oil cylinder I3 to make -180°~360° and the oil cylinder II6 to make 180°~360° rotational motion, the anchor rod propulsion assembly 1 can be positioned and drilled at any angle without any blind spots.

[0009] The present invention arranges three-level movement so that blind spots and dead angles will not be generated when the drill rod is drilling holes, and the top, side and end faces in the tunnel can be operated simultaneously, thereby improving the operation efficiency and reducing the labor intensity and operation cost; secondly, the telescopic inner and outer sleeves with four-side positioning are adopted to drive the anchor rod head to realize rapid horizontal, up and down and rotational movement; and finally, the compensating oil cylinder drives the propulsion chassis to make the top device close to the drilled area, so that the drill rod can drill holes without shaking.

[0010] Compared with the prior art, the present invention has the following characteristics:

[0011] 1. The drilling arm is flexible to operate and has no blind spots. It can drill holes at any angle.

[0012] 2. The drilling arm operation position is close to the drill arm, and the positioning is fast.
