A vertical worm gear mounting shell 33 is connected to the top of the vertical worm gear mounting shell 31. A vertical worm gear is disposed inside the vertical worm gear mounting shell 33, and the vertical worm gear meshes with the vertical worm gear for transmission. Through the horizontal angle adjustment mechanism 2 and the vertical angle adjustment mechanism 3, the drilling and grouting angle of the equipment can be flexibly adjusted to adapt to different slope variations. Furthermore, the optimal angle can be selected for drilling and grouting according to the needs of the project, making it more widely applicable.

[0031] In a preferred embodiment, the drilling and grouting mechanism 6 includes: a mounting frame 61, a turntable 62 disposed within the mounting frame 61, a drill bit through hole 63 formed in the upper middle part of the turntable 62, and dust suction through holes 64 and grouting through holes 65 respectively formed on both sides of the drill bit through hole 63. A wire groove 66 is also formed at the bottom end of the dust suction through hole 64 and the grouting through hole 65. A first motor 631 is slidably disposed within the drill bit through hole 63, and a drill bit 632 is fixedly connected to the output end of the first motor 631. A first magnet 633 is fixedly attached to the end of the first motor 631 away from the drill bit 632. A dust suction pipe 641 is slidably disposed within the dust suction through hole 64, and an L-shaped magnetic sheet 642 is connected to the end of the dust suction pipe 641 near the driving mechanism 7. A dust suction hose 643 is also disposed between the dust suction pipe 641 and the L-shaped magnetic sheet 642, and the dust suction hose 643 is connected to the end of the dust suction pipe 641. A grouting anchor rod 651 is slidably disposed within the grouting through hole 65. A grouting hose 652 is detachably connected to the bottom of the end of the grouting anchor rod 651 near the drive mechanism 7. The grouting hose 652 is connected to the grouting anchor rod 651.

[0033] The working process of this invention is as follows:

[0034] S1: Secure the base 1 to the existing support structure, such as tracks, mounting brackets, etc.;

[0035] S2: Adjust the angles of the horizontal angle adjustment mechanism 2 and the vertical angle adjustment mechanism 3 according to the project requirements, and then adjust the angle of the equipment drilling and grouting.

[0036] S3: Adjust the angle of the turntable 62 by the second motor 71 so that the drill bit through hole 63 is aligned with the output shaft of the hydraulic press 72, start the first motor 631 to drive the drill bit 632 to rotate, and at the same time start the hydraulic press 72 to push the first motor 631 to perform drilling operations on the slope.

[0037] S4: After drilling is completed, the first motor 631 is turned off, and then the second magnet 722 at the end of the output shaft of the hydraulic press 72 is attracted to the first magnet 633 at the tail of the first motor 631, thereby retracting the drill bit 632 into the turntable 62, and finally disengaging under the action of the limit block 67.

[0038] S5: After the output shaft of the hydraulic press 72 is withdrawn from the drill bit through hole 63, the turntable 62 is rotated again by the second motor 71 so that the dust suction through hole 64 is facing the output shaft of the hydraulic press 72. The hydraulic press 72 is started to push the dust suction pipe 641 into the drilled hole to suck out the debris and dust.

[0039] S6: After the vacuuming operation is completed, the second magnet 722 at the end of the output shaft of the hydraulic press 72 is attracted to the L-shaped magnetic sheet 642 at the tail of the vacuum tube 641, thereby retracting the vacuum tube 641 into the turntable 62, and finally disengaging under the action of the limit block 67.

[0040] S7: After the output shaft of the hydraulic press 72 is withdrawn from the dust suction hole 64, repeat the steps similar to S5 to perform grouting on the slope. It should be noted that when the grouting anchor 651 is fully inserted into the borehole, grouting is performed on the borehole through the grouting hose 652. After the grouting is completed, the grouting hose 652 is removed to complete the construction.
