[0057] Step 1: The straightening head 131 is opened under the action of the straightening cylinder 12; under the action of the driving motor 23, the rotating arm 22 drives the guide cylinder 25 to rotate to the hole mouth position, and under the action of the guide cylinder 24, extends into the borehole;

[0058] Step 2: The conveying device 6 drives the steel wire rope to move, and the moving end of the steel wire rope pushes the anchor out from the inside of the anchor storage box 5, and conveys it to the guide cylinder 25 through the anchor conveying pipe 4 and enters the hole;

[0059] Step 3: After the righting head 131 is closed under the action of the righting cylinder 12, the electric control valve is operated to switch the pressure oil into the righting sleeve 14, and the deformable seal 143 squeezes the wire rope;

[0060] Step 4: The guide cylinder 24 retracts, driving the guide cylinder 25 to be withdrawn from the straightening head 131 and return to the initial position;

[0061] Step 5: The motor of the conveying device 6 is reversed to draw the wire rope out of the guide tube 25. At this time, the anchoring agent falls to the top of the deformable sealing member 143 under the action of gravity;

[0062] Step 6: Driven by the feed cylinder, the anchor rod squeezes the deformable seal 143.
