[0002] In geotechnical engineering investigations, drilling is a crucial method for obtaining soil and rock samples and understanding underground geological conditions. However, existing geotechnical drilling equipment typically requires moving and repositioning the entire apparatus when drilling at different locations. This process is cumbersome, prone to positional deviations during movement, necessitating repeated calibrations, consuming significant time and manpower, and severely impacting work efficiency. Furthermore, frequent relocation can damage the equipment itself, increasing maintenance costs. Utility Model Content

Both ends of the vertical plate 9 have through holes, and a sliding rod 10 is movably sleeved inside the through holes. One end of the sliding rod 10 is fixedly connected to the U-shaped plate 3, and an anti-detachment ring is fixedly sleeved on the end of the sliding rod 10 away from the U-shaped plate 3 to prevent the sliding rod 10 from slipping out of the vertical plate 9 as much as possible. A pushing mechanism for moving the U-shaped plate 3 is provided on the side of the vertical plate 9 close to the U-shaped plate 3. A sliding plate 21 is slidably mounted on the inner side of the U-shaped plate 3. A drilling rod 6 is rotatably mounted on the lower surface of the sliding plate 21. A first motor 7 is fixedly mounted on the upper surface of the sliding plate 21, and the output end of the first motor 7 is fixedly connected to the drilling rod 6. A first transmission mechanism for moving the sliding plate 21 is provided on the inner side of the U-shaped plate 3, and a second transmission mechanism for rotating the turntable 2 is provided on the upper side of the bottom shell 1.

[0025] Reference Figure 1-3 The pushing mechanism includes a push rod 17 and a U-shaped slider 15. A groove is provided on the side of the U-shaped plate 3 near the vertical plate 9. A fixed rod is fixedly installed inside the groove. The U-shaped slider 15 is movably sleeved on the wall of the fixed rod. The push rod 17 is rotatably sleeved on the inner side of the U-shaped slider 15 through the first rotating rod 16. The lower end of the push rod 17 is fixedly sleeved on the second rotating rod 18. Both ends of the second rotating rod 18 are rotatably connected to side plates 19. One side of the side plate 19 is fixedly connected to the vertical plate 9. A second motor 20 is fixedly installed on the outer side of one side of the vertical plate 9. The output end of the second motor 20 is fixedly connected to one end of the second rotating rod 18.

[0026] Reference Figure 1-3 The first transmission mechanism includes a lead screw 4 and a third motor 5. The lead screw 4 is rotatably mounted on the inner side of the U-shaped plate 3. One side of the slide plate 21 is threadedly connected to the lead screw 4. The third motor 5 is fixedly mounted on the upper surface of the U-shaped plate 3. The output end of the third motor 5 is fixedly connected to one end of the lead screw 4. A limit rod 8 is provided parallel to one side of the lead screw 4. The two ends of the limit rod 8 are fixedly connected to the inner wall of the corresponding U-shaped plate 3. One side of the slide plate 21 is movably mounted on the limit rod 8, so that the slide plate 21 can slide stably.

[0027] Reference Figure 1-3 The second transmission mechanism includes a gear 13 and a gear ring 11. The side wall of the turntable 2 is provided with an annular groove. The gear ring 11 is fixedly sleeved on the inner wall of the annular groove. A transmission rod 12 is rotatably arranged on one side of the upper surface of the bottom shell 1.

[0028] In this invention, during use, the base shell 1 is first fixed to the exploration area. The fourth motor 14 is then started, which drives the transmission rod 12 to rotate. The gear 13 rotates accordingly and meshes with the gear ring 11, causing the turntable 2 to rotate on the base shell 1, thereby adjusting the orientation of the drill rod 6. When it is necessary to move the drill rod 6 horizontally, the second motor 20 is started, which drives the second rotating rod 18 to rotate. The lower end of the push rod 17 rotates accordingly, and the upper end of the push rod 17 pushes the U-shaped plate 3 to slide on the fixed rod, thereby driving the U-shaped plate 3 along the sliding rod 1. 0. Horizontal movement is used to adjust the horizontal position of the drill rod 6. After determining the drilling position, the third motor 5 is started, which drives the lead screw 4 to rotate. Under the guidance of the lead screw 4 and the limit rod 8, the slide plate moves downward. At the same time, the first motor 7 drives the drill rod 6 to rotate, so that the drill rod 6 drills into the rock and soil for exploration. During the drilling process, the drilling depth can be controlled by adjusting the third motor 5. If it is necessary to explore different directions or positions, the above operation of rotating the turntable 2 and moving the U-shaped plate 3 can be repeated. There is no need for the overall moving device.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
