[0034] The inside of the drill body 1 is provided with an internal combustion engine and a hydraulic drive structure, and the bottom of the drill body 1 is provided with two groups of tracks.

[0035] The upper end of the rotating platform 2 is fixedly connected with a hydraulic motor 12, the output end of the hydraulic motor 12 is fixedly connected with a first gear 13, the lower end of the rotating platform 2 is rotatably connected with a connecting shaft 14, the surface of the connecting shaft 14 is fixedly connected with a first gear ring 15, the first gear 13 is engaged with the first gear ring 15, and the connecting shaft 14 is fixedly connected with the drill body 1.

[0036] The right end of the rotating platform 2 is fixedly connected with a connecting frame 3, the drill support 4 is rotatably connected with the connecting frame 3, the upper end of the rotating platform 2 is hingedly connected with a first hydraulic rod 5, the output end of the first hydraulic rod 5 is hingedly connected with the drill support 4, and the upper end of the rotating platform 2 is fixedly connected with a limiting support 6.

[0037] The surface of the threaded rod 17 is threadedly sleeved with a movable frame 20, the upper end of the movable frame 20 is fixedly connected with a third hydraulic motor 21, the output end of the third hydraulic motor 21 is fixedly connected with a drill rod 22, and the drill rod 22 is rotatably connected with the movable frame 20.

[0038] The lower end of the drill rod 22 is conical, and the surface of the drill rod 22 is fixedly connected with two groups of spiral blades.

[0039] The left side of the rotating platform 2 is fixedly connected with a counterweight 11.

[0040] When the device is used, first, the internal combustion engine in the drill body 1 is started to drive the device, and the device is moved to the working site through the tracks on both sides, the hydraulic drive structure in the drill body 1 is started, the first hydraulic rod 5 is elongated to drive the drill support 4 to rotate around the connecting frame 3, so that the drill support 4 is rotated to be vertical, then the second hydraulic motor 16 is started to drive the threaded rod 17 to rotate in the inside of the drill support 4, the threaded rod 17 drives the movable frame 20 to descend, the movable frame 20 drives the third hydraulic motor 21 and the drill rod 22 to descend, the third hydraulic motor 21 is started to drive the drill rod 22 to rotate, so that the drill rod 22 drills downward, and the base hole is drilled on the ground, and since the soil in the base hole is guided out through the threads on the surface of the drill rod 22 when the drill rod 22 is used to drill the ground.

[0041] The water pump 8 is started in the process of leading the soil, and the water in the water tank 7 is pumped into the inside of the first water pipe 9 and the second water pipe 10, and then into the inside of the first limiting frame 18, and then sprayed out from the nozzle 26, so as to spray water to the drill pipe 22. When the drill pipe 22 rubs against the ground during drilling, a large amount of heat is generated, causing the temperature of the drill pipe 22 to rise sharply. Spraying water on the surface of the drill pipe 22 can effectively reduce its temperature, thereby preventing the drill pipe 22 from being damaged or causing safety hazards due to overheating, prolonging the service life of the drill pipe 22. Water has fluidity and can penetrate into the contact point between the drill pipe 22 and the ground, playing a lubricating role, which helps to reduce friction and make the drill pipe 22 more easily cut into the ground material. Watering can also help to flush away the debris and dust generated during drilling, keeping the drilling clean. Spraying water can reduce the temperature in the working environment and reduce the generation of dust, thereby improving the working environment and ensuring the safety of the operator.

[0042] In the process of lowering the movable frame 20, the third hydraulic motor 21 and the drill pipe 22 by the threaded rod 17, the threaded rod 17 drives the second gear 23 to rotate, and the second gear 23 drives the sealing ring 24 and the second gear ring 25 to rotate, so as to facilitate the rotation of the nozzle 26 during the lowering or raising of the drill pipe 22, and to facilitate the uniform spraying of water in the first limiting frame 18 to the drill pipe 22, so as to clean the surface of the drill pipe 22 and facilitate automatic cleaning during drilling, thereby improving the practicality and convenience of the device.

[0043] During use of the device, the counterweight 11 is fixed to the end of the rotating platform 2 away from the drilling rig support 4, so as to counterweight the two sides of the rotating platform 2 and balance the mass of the two sides of the rotating platform 2. The counterweight can increase the overall weight of the drilling machine, especially when it is arranged at the symmetrical position of the drill bit, which can significantly improve the stability and balance of the drilling machine. This helps to reduce the shaking and deviation of the drill bit during drilling, thereby improving the accuracy and efficiency of drilling. By adding the counterweight, the drilling machine can apply pressure more stably during drilling, making the drilling process smoother and reducing drilling quality problems caused by shaking.

[0044] When drilling is needed in multiple locations, the position of the device is moved by the caterpillar tracks on both sides of the drilling machine body 1, and the rotating platform 2 is rotated around the drilling machine body 1, facilitating drilling at other positions of the building pile foundation. The first gear 13 is driven to rotate by the hydraulic motor 12, and due to the meshing of the first gear 13 and the first gear ring 15, and the connection shaft 14 being fixed on the drilling machine body 1 and the first gear ring 15 being fixed on the connection shaft 14, the first gear 13 revolves around the first gear ring 15 during rotation, and the rotating platform 2 is rotated around the connection shaft 14 during the revolution of the first gear 13 around the first gear ring 15, facilitating the adjustment of the angle of the rotating platform 2 and the drilling range of the drill rod 22, improving the practicality and convenience of the device and the drilling efficiency of the device.

[0045] Further, the second gear 23 is driven to rotate by the threaded rod 17, facilitating the spraying of water from the nozzle 26 to the drill rod 22 during drilling, and the rotation of the sealing ring 24 when the drill rod 22 is ascending or descending, facilitating the uniform spraying of water inside the first limiting frame 18 to the drill rod 22, facilitating the cleaning of the surface of the drill rod 22, improving the practicality and convenience of the device, and reducing the temperature in the working environment and the generation of dust through water spraying, thereby improving the working environment and ensuring the safety of the operator.

[0046] Spraying water from the nozzle 26 to the drill rod 22 can effectively reduce the temperature of the drill rod 22, thereby preventing the drill rod 22 from being damaged or causing safety hazards due to overheating, and improving the service life of the drill rod 22.

[0047] Through the rotation of the rotating platform 2, the drilling range of the drill rod 22 is facilitated, the practicality and convenience of the device are improved, and the drilling efficiency of the device is improved.
