[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a drilling tool for geological engineering exploration, including a support frame 1, with brackets 2 installed on both sides of the support frame 1, a hydraulic rod 3 installed on the top of the support frame 1, a support plate 4 fixedly connected to the output end of the hydraulic rod 3, an annular groove 5 opened at the bottom of the support plate 4, an annular slide rail 6 rotatably connected inside the annular groove 5, two support rods 7 installed at the bottom of the annular slide rail 6, an adjusting frame 8 fixedly connected to the bottom of the two support rods 7, a support column 9 rotatably connected to the bottom of the adjusting frame 8, and a drill bit 10 fixedly connected to one end of the support column 9 through a flange. This, combined with the extension of the hydraulic rod 3, facilitates drilling into the ground for geological exploration. Limiting grooves 2 are opened inside the support frame 1 on both sides corresponding to the hydraulic rod 3. 9. A limiting rod 30 is slidably connected inside the limiting groove 29. One end of the limiting rod 30 is fixedly connected to the support plate 4, which helps to assist in supporting the support plate 4 and the drilling structure, making the operation of the hydraulic rod 3 more stable. A positioning cover 32 is installed at the bottom of the support plate 4 and outside the two support rods 7. The positioning cover 32 has multiple insertion holes 33 inside. A bolt 34 is threaded inside one of the support rods 7. One end of the bolt 34 passes through one of the insertion holes 33. When the bolt 34 rotates, its other end moves through the insertion hole 33, fixing the support rod 7 and the adjusting frame 8, or pulling it out from the insertion hole 33. With the rotation of the adjusting frame 8, it is convenient to adjust the position of the adjusting frame 8 and the drill bit 10, without having to repeatedly disassemble the bracket 2 from the ground, so that the drill bit 10 can be adjusted. The device can drill and sample at different locations. The adjusting frame 8 has three rotating shafts connected sequentially: shaft 11, shaft 2, and shaft 3. The support plate 4 has a slot 17 inside, and a motor 18 is installed inside the slot 17. The output end of the motor 18 is fitted with a bearing seat and fixedly connected to shaft 11 via a coupling, providing power for the rotation of shaft 11. Multiple heat dissipation holes 26 are located inside the support plate 4 at the top of the slot 17. A fan 27 is installed inside the slot 17 on one side of the motor 18 to facilitate heat dissipation. Gears 14, 25, and 316 are respectively installed on the outer sides of shafts 11, 22, and 313. The rotating shaft 13 is fixedly connected to the support column 9, and the position of the rotating shaft 11 is consistent with the center point of the annular slide rail 6 and the adjusting frame 8. Through the meshing of gear 14, gear 25, and gear 316, the rotating shaft 11 and the drill bit 10 are driven to rotate. This facilitates the rotation of the drill bit 10 while the positions of the motor 18 and the rotating shaft 11 remain unchanged and will not rotate or shift with the rotation of the adjusting frame 8, which helps to avoid cable tangling. A controller 31 is installed on the outer wall of one of the brackets 2. Multiple positioning holes 19 are opened on one side of the bracket 2. A positioning sleeve 20 is fitted on the outer side of the bracket 2. Universal wheels 21 are installed on the corresponding two sides of the bottom of the positioning sleeve 20 to facilitate the displacement of the device. A sliding groove 22 is opened on the inner wall of the positioning sleeve 20.The sliding groove 22 has an internal threaded connection to a threaded rod 23. One end of the threaded rod 23 is fixedly connected to a pin 24. One end of the pin 24 is inserted into one of the positioning holes 19, causing the pin 24 to shift as the threaded rod 23 rotates. The pin 24 can be inserted into or removed from the positioning hole 19, fixing the positioning sleeve 20. The sliding of the positioning sleeve 20 facilitates adjustment of the height of the positioning sleeve 20 and the caster 21, controlling the extension and retraction of the caster 21. The diameter of the pin 24 is larger than the diameter of the threaded rod 23, which helps prevent the threaded rod 23 and the pin 24 from detaching from the positioning sleeve 20. The bracket 2 has an internal mounting hole 28 for easy fixing to the ground with nails or other positioning components.

[0023] In summary, this drilling tool for geological engineering exploration is powered by a mobile power supply. The positioning sleeve 20 on the outer side of the support 2 is slid upwards, raising the height of the universal wheel 21 at the bottom of the positioning sleeve 20. The universal wheel 21 is equipped with a brake, lifting it off the ground. The threaded rod 23 connected to the positioning sleeve 20 is rotated, inserting one end of the threaded rod 23 into the corresponding positioning hole 19 inside the support 2. After fixing the support 2 to the ground, the motor 18 inside the support plate 4 drives the rotating shaft 11 inside the adjusting frame 8 to rotate. Gears 14, 15, and 16 on the outer sides of rotating shaft 11, 12, and 13 mesh, and the rotating shaft... Under the fixed connection of the support column 9 on the drill bit 10 and the hydraulic rod 13, the drill bit 10 is driven to rotate through the shaft 11. At the same time, the hydraulic rod 3 is activated to push the support plate 4 and the adjusting frame 8 to move down, so that the drill bit 10 at the bottom of the adjusting frame 8 can be inserted into the ground for drilling and sampling. Since the two support rods 7 on the adjusting frame 8 are fixed to the rotating annular slide rail 6 inside the support plate 4, the adjusting frame 8 can rotate to adjust the position of the drill bit 10. The bolt 34 connected to the internal thread of the support rod 7 is rotated so that one end of the bolt 34 passes through the corresponding insertion hole 33 in the positioning cover 32 at the bottom of the support plate 4, thus fixing the position of the support rod 7, the adjusting frame 8 and the drill bit 10.

[0024] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The installation methods between equipment are also the same as conventional installation methods in the prior art. For example, the two ends of the shaft-shaped parts are connected by bearings, the connection position of the valve component is provided with anti-leakage rubber strips, the outside of the threaded rod or screw is provided with dust cover, and the equipment can be driven by either built-in battery or external power supply. The control method is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, this utility model will not explain the control method and circuit connection in detail.
