[0002] In the excavation of tunnels in rock and soil, drilling machines are required for the excavation operation. However, current drilling machines lack guiding mechanisms. Therefore, patent CN 221646886 U discloses a rock and soil drilling guiding mechanism, which relates to the field of rock and soil drilling. It includes a sliding guide beam for installation and fixing on the drilling machine. A lifting structure is slidably connected to the sliding guide beam through a sliding structure. A first guide hoop is installed and connected to the lifting structure. A second guide hoop is detachably connected to the first guide hoop through bolts.
[0003] However, the aforementioned patent uses the first guide hoop and the second guide hoop to guide and position the drill rod. But the drill rod will rotate during the forward movement, and during the rotation, it will directly rub against the first guide hoop and the second guide hoop, thereby affecting the tunneling speed and causing damage to the first guide hoop and the second guide hoop, thus affecting the guiding quality. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a rock and soil drilling guide mechanism that enables the drill rod to rotate and advance smoothly through a rotatable guide ring and a rotating first ball, thereby solving the problems mentioned in the background art.

The guide ring is disposed inside the clamping ring. The clamping ring is divided into two outer rings. The guide ring is divided into two half rings, consisting of a first half ring and a second half ring. The outer ring surfaces of the first half ring and the second half ring are provided with arc-shaped grooves. The arc-shaped grooves are combined to form a positioning groove. Positioning blocks are installed on the inner ring surfaces of the outer rings. The positioning blocks are combined to form a positioning ring. The positioning ring is slidably disposed in the positioning groove.

[0007] As a preferred technical solution, multiple second ball grooves are provided on both sides of the positioning block, and a second ball is movably installed in each of the second ball grooves. A portion of each second ball extends outward along the opening of the second ball groove and contacts both sides of the positioning groove.
[0008] As a preferred technical solution, multiple third ball grooves are provided on the inner ring surfaces of the first and second half rings, and a third ball is movably installed in each of the third ball grooves, with a portion of the third ball extending to the outside through the opening of the third ball groove.
[0009] As a preferred technical solution, the open end face of the second half ring is provided with multiple limiting grooves, and the open end face of the first half ring protrudes to form limiting parts at the limiting grooves, and the limiting parts are all inserted into the limiting grooves.
[0010] As a preferred technical solution, the open ends of the outer ring are all bent outward to form a fixing part, and the fixing part is provided with fixing holes. Bolts are inserted into the corresponding fixing holes, and one end of the bolt is threaded to a nut that presses the outer ring inward.
[0011] As a preferred technical solution, a fixed seat connected to the lifting rod is installed on the outer ring on one side.
[0012] The beneficial effects of this utility model are: the utility model has a simple structure, is fixed by a clamping ring, and the guide ring is movably sleeved on the outside of the drill rod. The rotatable guide ring and the third ball avoid affecting the rotation and forward movement of the drill rod, and the guide ring can be quickly disassembled, which facilitates replacement and increases adaptability.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a rock and soil drilling guide mechanism, which includes a clamping ring and a guide ring. The guide ring is disposed inside the clamping ring. The clamping ring is divided into two outer rings 1, and the guide ring is divided into two half-rings 2 and 3. The outer ring surfaces of the first half-ring 2 and the second half-ring 3 are provided with arc-shaped grooves, which are combined to form a positioning groove 10. Positioning blocks 7 are installed on the inner ring surfaces of the outer rings 1, and the positioning blocks 7 are combined to form a positioning ring. The positioning ring is slidably disposed in the positioning groove 10.
[0021] In this embodiment, the inner ring surface of the positioning block 7 is provided with a plurality of first ball grooves, and a first ball 5 is movably installed in each of the first ball grooves. A portion of the first ball 5 extends to the outside through the opening of the first ball groove and is in contact with the inner ring surface of the positioning groove 10.
[0022] In this embodiment, multiple second ball grooves are provided on both sides of the positioning block 7, and a second ball 8 is movably installed in each of the second ball grooves. A portion of the second ball 8 extends to the outside through the opening of the second ball groove and contacts both sides of the positioning groove 10.
[0023] The guide ring is centered by the first sphere and axially positioned by the second sphere, preventing it from tipping over and ensuring stability after installation.
[0024] In this embodiment, the inner surfaces of the first half-ring 2 and the second half-ring 3 are provided with a plurality of third ball grooves, and a third ball 9 is movably installed in each of the third ball grooves. A portion of the third ball 9 extends to the outside through the opening of the third ball groove.
[0025] In this embodiment, the open end face of the second half ring 3 is provided with multiple limiting grooves, and the open end face of the first half ring 2 protrudes to form limiting parts 4 at the limiting grooves. The limiting parts 4 are all inserted into the limiting grooves. The limiting parts and the limiting grooves enable the first half ring and the second half ring to be precisely connected, avoiding misalignment between the two.
[0026] In this embodiment, the open ends of the outer ring 1 are all bent outward to form a fixing part 6. The fixing part 6 is provided with fixing holes, and bolts are inserted into the corresponding fixing holes. One end of the bolt is threaded to a nut that presses the outer ring 1 inward.
[0027] In this embodiment, a fixed seat connected to the lifting rod is installed on the outer ring 1 on one side, so that the height of this device can be adjusted by the lifting rod.
[0028] During installation, the first and second half-rings are first fitted onto the outside of the drill rod, and the limiting part is inserted into the limiting groove. Then, the outer ring is fitted onto the outside of the guide ring. The positioning block on the outer ring can be inserted into the arc-shaped groove. After the outer rings are fitted together, the positioning blocks will combine to form a positioning ring. The positioning ring can wrap around the outside of the positioning groove. The second and third balls can center the guide ring inside the clamping ring. The third and second balls reduce the friction between the guide ring and the clamping ring. During the drill rod advance, the third ball on the first and second half-rings will rotate. When the drill rod rotates, it will drive the rotation of the third ball and the guide ring, which greatly reduces friction and facilitates the drilling of the drill rod.
[0029] After the clamping ring is opened, the first and second half rings can be directly removed, making them easy to replace. In addition, there are multiple guide rings with different inner diameters, which can accommodate drill pipes of different diameters and increase adaptability.
[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
