The integrated grouting device for drilling and grouting reinforcement of the surrounding rock of the weakly cemented roadway according to claim 1, characterized in that, an installation box (13) is fixedly installed on the side of the body (1), and the installation A first motor (14) is fixedly installed in the box (13), and one end of the first motor (14) close to the body (1) is fixedly connected to the mounting plate (11). 9. The integrated grouting device for drilling and grouting reinforcement of weakly cemented roadway surrounding rock as claimed in claim 1, characterized in that, the outer surface of the connecting rod (32) is fixedly equipped with a deflection ball (33), so that Described deflection ball (33) is hingedly installed in the bottom plate inside of mobile frame (3). 10. An integrated grouting method for drilling and grouting reinforcement of the surrounding rock of the weakly cemented roadway, characterized in that it comprises the following steps: Step 1. Turn on the first motor (14) to drive the installation plate (11) to rotate, the rotation of the installation plate (11) drives the hydraulic telescopic rod (12) to rotate, and the rotation of the hydraulic telescopic rod (12) drives the support plate (2) Turn to adjust the azimuth of the drilling device. Step 2. Insert one end of the drill pipe (51) into the limit block (5), turn the limit rod (52) to drive the limit plate (53) to rotate, and make the limit plate (53) break away from the limit groove (55) Inside, now the spring (54) releases the power of contraction, and drives the stop rod (52) to move inwardly and be inserted in the drill rod (51) inside, and the drill rod (51) is limited. Step 3, turn on the second motor (44) to drive the pinion gear (45) to rotate, the rotation of the pinion gear (45) drives the large gear (42) to rotate, and the rotation of the large gear (42) drives the rotating disc (41) to rotate , the rotation of the rotating disk (41) drives the limit block (5) to rotate, and the rotation of the limit block (5) drives the drill pipe (51) to rotate Step 4, open the power machine (22) to drive the screw rod (23) to rotate, drive the slide block (31) to move by the rotation of the screw rod (23), drive the mobile frame (3) to move by the movement of the slide block (31), and pass the mobile frame ( 3) The movement drives the drill rod (51) to move and drill holes. Step five, turn the screw rod (64), drive the moving rod (61) to move by the rotation of the screw rod (64), and drive one end of the connecting rod (32) to move through the movement of the moving rod (61), thereby driving the connecting rod ( 32) The overall deflection occurs, the angle of the drill rod (51) is adjusted, and the moving distance of the moving rod (61) is controlled, and the drill rod (51) is fine-tuned to prevent the drill rod (51) from breaking during reaming. Step 6, open and drive the round gear (38) to rotate through the turning machine (37), drive the gear ring (35) to rotate through the rotation of the round gear (38), and drive the ring (34) to rotate through the rotation of the gear ring (35), The circular motion of the connecting block (39) is driven by the rotation of the ring (34), the circular motion of the fixed rod (6) is driven by the circular motion of the connecting block (39), and the circular motion of the fixed rod (6) is driven to drive the mounting block (321) Circular movement, through the circular movement of the installation block (321), the connecting rod (32) is driven to rotate, so that the drill pipe (51) rotates along the deflection direction to ream the hole. After the reaming is completed, insert the grouting pipe Grouting is carried out in the hole to reinforce the roadway surrounding rock.
