Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically a rock drilling device for geological exploration. Background Technology

[0002] Drilling is an important technical means in geological exploration. A drilling rig drills downwards from the surface, creating cylindrical boreholes in the strata to identify and delineate them. Core samples, mineral samples, and soil samples can be obtained from different depths within the borehole for analysis and research, used to determine the physical and mechanical properties of the rocks and soil layers, and to provide information for design requirements.

[0003] Existing gasoline drilling machines require two people to manually control the drilling angle by holding the handles. However, the significant vibrations generated during drilling can cause numbness in the operator's hands and arms, interfering with the stability of angle adjustment and easily leading to deviations in the drilling angle. This affects the accuracy of rock sampling and makes it difficult to control the drilling angle. Utility Model Content

[0004] The purpose of this invention is to provide a rock drilling device for geological exploration to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A geological exploration rock drilling device includes a gasoline-powered drilling rig and a drill bit disposed at its lower end, and further includes: A fixing component is set on the outside of the drill bit. The fixing component includes a fixing ring. An inner ring is fixedly installed on the inner surface of the fixing ring by a support rod. Multiple second sliding sleeves are fixedly embedded at equal angles on the outer surface of the inner ring. A first sliding rod is slidably inserted into the inside of the second sliding sleeve. An adjustment component is located on the outer side of the inner ring. The adjustment component includes two rotating rings that are rotatably connected to both ends of the outer surface of the inner ring. Arc-shaped slide rails are fixedly installed at equal angles on the outer side of the rotating rings.

[0006] Furthermore, multiple connecting ears are fixedly installed on the outer surface of the fixing ring, and a U-shaped frame is fixedly installed at one end of the first slide rod, with rollers rotatably connected inside the U-shaped frame.

[0007] Furthermore, a slider is fixedly installed at the other end of the first slider, and the two ends of the slider are slidably connected to the arc-shaped slide rails at the corresponding positions.

[0008] Furthermore, the outer surfaces of the two arc-shaped slide rails at corresponding positions are fixedly connected with arc-shaped connecting plates, and the inner surfaces of the two rotating rings are fixedly connected with multiple U-shaped connecting plates at equal angles, with the U-shaped connecting plates movably fitting against the inner ring.

[0009] Furthermore, an extension plate is symmetrically fixedly installed on the upper surface of the fixed ring, a knob is screwed into the inside of the extension plate, a guide block is rotatably connected to the lower end of the knob, and a second slide rod is fixedly installed on the upper end of the guide block, which slides through the extension plate.

[0010] Furthermore, the handle of the gasoline drilling machine is symmetrically and fixedly installed with a first sliding sleeve on the outside. A hollow sliding rod is slidably inserted inside the first sliding sleeve, and a connecting rod is movably inserted at the upper end of the two hollow sliding rods.

[0011] Preferably, the outer surface of the fixing ring is symmetrically fixed with threaded sleeves, and the lower end of the hollow slide rod is screwed into the threaded sleeves.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By turning the knob, the guide block moves downward, simultaneously pushing multiple arc-shaped slide rails and a rotating ring to rotate. This causes the arc-shaped slide rails to push the first slide rod to slide inside the second slide sleeve, adjusting the position between multiple rollers. This allows the rollers to limit and clamp drill bits of different sizes. Simultaneously, the sliding connection between the first slide sleeve and the hollow slide rod further improves the accuracy of the drill bit's drilling angle. By fixing the fixing component to the rock surface and adjusting the component to limit the drill bit's movement direction, the drill bit can drill along a specific direction. This reduces the impact of the numbness caused by manual support on the drill bit's drilling stability, reduces the impact of vibration on the drill bit's angle adjustment, makes the drill bit's drilling angle easier to control, and improves the accuracy of rock sampling.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 In this embodiment of the present invention, a rock drilling device for geological exploration includes a gasoline drilling machine 1 and a drill bit 101 disposed at its lower end, and also includes a fixing component 2 disposed on the outside of the drill bit 101. The fixing component 2 includes a fixing ring 201, an inner ring 203 fixedly installed on the inner surface of the fixing ring 201 by a support rod, and a plurality of second sliding sleeves 204 fixedly embedded at equal angles on the outer surface of the inner ring 203. A first sliding rod 205 is slidably inserted into the inner sliding sleeve 204. An adjusting component 3 is disposed on the outside of the inner ring 203. The adjusting component 3 includes two rotating rings 301 rotatably connected to the two ends of the outer surface of the inner ring 203, and an arc-shaped slide rail 302 fixedly installed at equal angles on the outer side of the rotating rings 301.

[0017] Specifically, by fixing the fixing component 2 to the rock surface and adjusting the component 3 to limit the position and drilling angle of the drill bit 101, the drill bit 101 can drill into the rock in a specific direction, making the drilling angle of the drill bit 101 easier to control and improving the sampling accuracy. Example 1

[0018] like Figure 2-4As shown, in this embodiment, multiple connecting ears 202 are fixedly installed on the outer surface of the fixing ring 201. The fixing ring 201 is fixed to the rock surface by passing through the connecting ears 202 with pins. A U-shaped frame 206 is fixedly installed at one end of the first slide rod 205. A roller 207 is rotatably connected inside the U-shaped frame 206. A slider 208 is fixedly installed at the other end of the first slide rod 205. The two ends of the slider 208 are slidably connected to the arc-shaped slide rail 302 at the corresponding positions. Arc-shaped connecting plates 303 are fixedly connected to the outer surfaces of the two arc-shaped slide rails 302 at the corresponding positions. The arc-shaped connecting plates 303 increase the firmness and connection between the two arc-shaped slide rails 302. Multiple U-shaped connecting plates 304 are fixedly connected at equal angles to the inner surfaces of the two rotating rings 301. The U-shaped connecting plates 304 increase the firmness and structural stability between the two rotating rings 301, and the U-shaped connecting plates 304 are movably fitted with the inner ring 203.

[0019] In this embodiment, rotating the two rotating rings 301 causes multiple arc-shaped slide rails 302 to rotate simultaneously. Through the sliding connection between the arc-shaped slide rails 302 and the slider 208, and under the sliding limit of the first slide rod 205 and the second slide sleeve 204, the arc-shaped slide rails 302 push the first slide rod 205 to slide inside the second slide sleeve 204. Adjusting the position between multiple rollers 207 allows multiple rollers 207 to limit and clamp drill bits 101 of different sizes, making them suitable for different drill bits 101. Thus, by fixing the fixing component 2 to the rock surface and limiting the movement direction of the drill bit 101 by the adjusting component 3, the drill bit 101 can drill along a specific direction, reducing the impact of numbness during manual support on the drilling stability of the drill bit 101, reducing the impact of vibration on the angle adjustment of the drill bit 101, making the drilling angle of the drill bit 101 easier to control, and improving the accuracy of rock sampling.

[0020] like Figure 4 and Figure 5 As shown, in this embodiment, an extension plate 305 is symmetrically fixedly installed on the upper surface of the fixed ring 201. A knob 306 is screwed into the inside of the extension plate 305. A guide block 307 is rotatably connected to the lower end of the knob 306. A second slide rod 308 is fixedly installed on the upper end of the guide block 307. The second slide rod 308 slides through the extension plate 305.

[0021] In practice, turning the knob 306, through its engagement with the extension plate 305, and under the sliding limit of the second slide rod 308 and the extension plate 305, causes the knob 306 to drive the guide block 307 to move downward. The conical surface of the guide block 307 abuts against the arc-shaped connecting plate 303, simultaneously pushing multiple arc-shaped slide rails 302 and rotating ring 301 to rotate, providing power for the adjustment of the roller 207. At the same time, it works with the drill bit 101 to limit the position of the roller 207, improving the stability of the roller 207. Example 2

[0022] Based on Example 1, in order to solve the problem that the hand of the gasoline drilling machine 1 is prone to vibration and tilting during the initial drilling of the drill bit 101 due to the close proximity of the roller 207 to the rock strata.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, a first sliding sleeve 102 is symmetrically fixedly installed on the outer side of the handle of the gasoline drilling machine 1. A hollow sliding rod 103 is slidably inserted inside the first sliding sleeve 102, and a connecting rod 104 is movably inserted at the upper end of the two hollow sliding rods 103. A threaded sleeve 209 is symmetrically fixedly connected to the outer surface of the fixing ring 201, and the lower end of the hollow sliding rod 103 is screwed into the threaded sleeve 209.

[0024] In practice, after the drill bit 101 is inserted between multiple rollers 207, two hollow slide rods 103 are screwed into the threaded sleeve 209 through the first slide sleeve 102. Then, the connecting rod 104 is inserted into the upper end of the two hollow slide rods 103 to improve the stability of the two hollow slide rods 103. Thus, through the sliding connection between the first slide sleeve 102 and the hollow slide rods 103, the accuracy of the drilling angle of the drill bit 101 is further improved.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
