[0038] The front and rear sides of the side blocks 24 are fixedly connected to connecting blocks 27, which are driven by the side blocks 24 to slide up and down. A guide shaft 28 is slidably connected to the interior of the connecting blocks 27, which provides guidance for the sliding movement of the guide shafts 28. Springs 29 are mounted on the exterior of the guide shafts 28, which restrict the springs 29 so that they are evenly stressed. A protective frame 30 is fixedly connected to the bottom sides of the two guide shafts 28. The protective frame 30 protects the drilling area from flying debris. An arc-shaped plate is fixedly connected to the top side of the guide shafts 28 to prevent the springs 29 from bouncing off. The bottom ends of the multiple springs 29 are fixedly connected to the top and sides of the protective frame 30. The top side of the base plate 20 contacts the bottom side of the protective frame 30, completely covering the drilling area. Strip openings 32 are provided at the front and rear ends of the connecting frame 18 to guide the sliding movement of the guide blocks 23.

[0039] Working principle: First, guide the vehicle frame 1 to the area to be drilled, and then drive the push plate 5 to slide downward by driving the air cylinder 4, thereby driving the connecting column 7 to slide, and then driving the conical head 10 to slide downward. At the same time, the sliding column 8 slides downward with the conical head 10 under the action of gravity, and then the conical head 10 will press against the soil and push downward, thereby increasing the overall stability. As the sliding column 8 falls, when the positioning ring 9 presses against the positioning plate 6, only the connecting column 7 pushes the conical head 10 to slide deep into the soil, and then the sliding column 8 stops sliding. At the same time, the connecting column 7 will also drive the connecting plate 11 to slide, thereby driving the transmission column 12 to slide, and the inclined opening 14 opened inside the inclined opening 14 is used to make multiple transmission columns 12 push the reinforcement plate 13 to slide respectively, so that the multiple reinforcement plates 13 slide to the far side and are inserted into the soil laterally, thereby performing secondary positioning, and then improving the overall stability;

[0040] After the reinforcement is completed, the screw rod 21 is driven to rotate by driving motor 1 31, thereby driving the slide plate 22 to slide downward under the restriction of the guide block 23, and then driving the side block 24 to slide downward, and then driving motor 2 25 to slide downward, and driving motor 25 to drive the drilling column 26 to rotate, so that the drilling column 26 rotates and drills downward, and at the same time, it will drive the protective frame 30 to press against the bottom plate 20, so that the bottom plate 20 can push the guide shaft 28 with an upward reaction force, and the side block 24 will also drive the connecting block 27 to slide downward and squeeze the spring 29, so that the spring 29 can store elastic potential energy, and then give the protective frame 30 a reverse force to adapt to the drilling depth, so that it can complete the covering of the drilling area and avoid mud splashing, thereby improving the comfort of the drilling work.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
