A circular support plate 401 is fixedly connected to the lower end of the movable cylinder 4.

[0024] Furthermore, a counterweight 105 is fixedly connected to one side of the middle part of the upper end of the drilling machine main body 1. The controller 102 is connected to the gyroscope 101 through a data cable, and the gyroscope 101 is used to detect the horizontal state of the drilling machine main body 1 in real time during operation.

[0025] Furthermore, all four hydraulic telescopic rods 2 are connected to the controller 102 through control lines, and the controller 102 independently controls the four hydraulic telescopic rods 2 respectively.

[0026] Furthermore, a circular hole 104 is provided in the middle of the upper end of the L-shaped wing plate 103. A telescopic end 201 is provided inside the hydraulic telescopic rod 2. The lower end of the telescopic end 201 passes through the circular hole 104 and is fixedly connected to the upper end of the drill rod 3. After the drilling machine main body 1 moves to the drilling position, the telescopic end 201 on the hydraulic telescopic rod 2 extends downward, so that the drill rod 3 is inserted into the ground downward. The four drill rods 3 are inserted into the ground synchronously to provide stability for the drilling machine main body 1 during operation.

[0027] Furthermore, a telescopic groove 402 is provided inside the movable cylinder 4, and a second fixing ring 403 is fixedly connected to the lower middle part of the telescopic groove 402 and on the inner end face of the movable cylinder 4.

[0028] Furthermore, a first fixing ring 302 is fixedly connected to the upper middle part of the outer end face of the drill rod 3 and inside the movable cylinder 4. A spring 404 is provided between the second fixing ring 403 and the first fixing ring 302. When the drill rod 3 descends, the movable cylinder 4 is driven to descend synchronously, so that the circular support plate 401 at the lower end of the movable cylinder 4 contacts the ground to provide support. The drill rod 3 continues to descend, so that the spring 404 is compressed, and the circular support plate 401 presses down the ground, so that the four circular support plates 401 press down the ground synchronously to provide support for the drilling machine main body 1. When the drilling machine main body 1 tilts due to vibration during operation, the tilt direction is detected by the gyroscope 101, and one or two hydraulic telescopic rods 2 in the tilt direction are controlled by the controller 102 to continue driving the drill rod 3 to descend, increasing the distance between the circular support plate 401 and the L-shaped wing plate 103 to offset the tilt amount and ensure the horizontal state of the drilling machine main body 1.

[0029] Furthermore, a mud scraping pipe 405 is fixedly connected to the middle of the circular support plate 401.

[0030] Working principle: When in use, a gyroscope 101 is fixedly arranged in the middle of the upper end of the drilling machine main body 1. A controller 102 is fixedly arranged in the middle of the upper end of the drilling machine main body 1 and on one side of the gyroscope 101.

Circular holes 104 are arranged in the middle of the upper ends of the L-shaped wing plates 103. A telescopic end 201 is arranged inside the hydraulic telescopic rod 2. The lower end of the telescopic end 201 passes through the circular hole 104 and is fixedly connected to the upper end of the drill rod 3. When the drilling machine main body 1 moves to the drilling position, the telescopic end 201 on the hydraulic telescopic rod 2 extends downward, causing the drill rod 3 to be inserted into the ground downward. By synchronously inserting the four drill rods 3 into the ground, stability is provided for the drilling machine main body 1 during operation. A telescopic groove 402 is arranged inside the movable cylinder 4. A second fixing ring 403 is fixedly connected to the lower middle of the telescopic groove 402 and on the inner end face of the movable cylinder 4. A first fixing ring 302 is fixedly connected to the upper middle of the outer side end face of the drill rod 3 and inside the movable cylinder 4. A spring 404 is arranged between the second fixing ring 403 and the first fixing ring 302. When the drill rod 3 descends, it drives the movable cylinder 4 to descend synchronously, causing the circular support plate 401 at the lower end of the movable cylinder 4 to contact the ground to provide support. The drill rod 3 continues to descend, compressing the spring 404, causing the circular support plate 401 to press down on the ground, and causing the four circular support plates 401 to synchronously press down on the ground to provide support for the drilling machine main body 1. When the drilling machine main body 1 tilts due to vibration during operation, the tilt direction is detected by the gyroscope 101, and one or two hydraulic telescopic rods 2 in the tilt direction are controlled by the controller 102 to continue driving the drill rod 3 to descend, increasing the distance between the circular support plate 401 and the L-shaped wing plate 103, offsetting the tilt amount, and ensuring the horizontal state of the drilling machine main body 1. A mud scraping pipe 405 is fixedly connected to the middle of the circular support plate 401. When the drill rod 3 is retracted, the mud on the surface of the drill rod 3 is scraped by the mud scraping pipe 405. The lower end of the drill rod 3 passes through the middle of the mud scraping pipe 405 and extends to the lower end and is fixedly connected to a conical head 301. The conical head 301 enables the drill rod 3 to be smoothly inserted into the ground.
