Description

A drilling device for geological resource exploration Technical Field

[0001] This utility model relates to the technical field of geological exploration sampling equipment, specifically a drilling device for geological resource exploration. Background Technology

[0002] Geological resource exploration is a process that involves studying and analyzing information such as soil properties, distribution, genesis, depositional history, and soil sequence to enable land use planning, soil improvement, and environmental assessment in a given area. Through methods such as drilling, soil samples are obtained at different depths to further analyze the physical and chemical properties of the soil and understand parameters such as soil structure, texture, and water content.

[0003] For example, application number CN202322470188.3 discloses a drilling device for geological exploration, including a sleeve. A spiral blade is fixedly connected to the outside of the sleeve, and a shovel head is threadedly connected to the bottom of the sleeve. A positioning structure is provided near the bottom of the sleeve. This drilling device for geological exploration, by setting the positioning structure, allows for drilling and sampling in relatively flat areas. By pulling the ring, the three connecting rods can be opened at a certain angle, and by stepping on the pedal, the cone can be driven into the soil. This ensures that the sleeve remains perpendicular to the direction of gravity during drilling and sampling, making the sampling data accurate and reliable. When drilling and sampling in areas with a certain slope, the height of the movable rod can be adjusted to adapt to different inclination angles, and the position of the pedal can be adjusted to fix the positioning structure, ensuring that the sleeve remains perpendicular to the direction of gravity during drilling. This enhances the accuracy and functionality of the drilling device.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of traditional drilling devices that rely on manual alignment, are prone to errors and data distortion during continuous drilling, and suffer from low practicality and functionality in sloping areas such as hills and slopes where the slope affects the direction and position of the borehole, making it difficult to remove soil completely and leaving soil residue on the inner wall of the pipe that affects subsequent drilling and sampling, and making cleaning troublesome, the drilling device of the aforementioned equipment is manually rotated to drill into the soil. As the drilling device descends deeper into the soil, the user needs to gradually bend over to rotate it, which is not only tiring but also makes it difficult to rotate the drilling device due to changes in body posture. Summary of the Invention

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a drilling device for geological resource exploration, which has the advantage of being easy to use. It solves the problem that the drilling device of the above-mentioned equipment is manually rotated to drill into the soil, and as the drilling device goes deeper into the soil, the user needs to gradually bend over to cooperate in order to turn it, which is not only easy to get tired, but also makes it difficult to turn the drilling device due to changes in body posture.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for geological resource exploration, comprising a horizontal frame and a drilling device, wherein the surface of the drilling device is threadedly connected to the inner wall of the horizontal frame, a stud is movably connected to the top left side of the horizontal frame via a pin, a first gear is slidably connected to the surface of the stud, a second gear is meshed with the right side of the first gear, the inner wall of the second gear is fixedly connected to the top of the surface of the drilling device, and a support assembly is movably connected to the top left side of the horizontal frame via a pin.

[0007] In a preferred embodiment of this invention, the support assembly includes a sleeve, the top right side of which is movably connected to the top left side of the horizontal frame via a pivot pin, and the inner wall of the sleeve is threaded with an adjusting screw.

[0008] As a preferred embodiment of the present invention, clamping plates are provided on both sides of the second gear, and the inner walls of the clamping plates are fixedly connected to the surface of the drilling device, with the right sides of the two sides of the first gear located between the inner sides of the clamping plates.

[0009] As a preferred embodiment of this invention, a handwheel is connected to the top of the flower stem, and the handwheel is used to rotate the flower stem.

[0010] As a preferred embodiment of this utility model, the inner side of the clamping plate is inlaid with balls, and both sides of the first gear and the second gear are in contact with the inner side of the balls. The balls are arranged in a ring and are evenly distributed.

[0011] As a preferred embodiment of this invention, a half-cover is fitted onto the surface of the first gear, and the inner wall of the half-cover is slidably connected to the surface of the flower rod.

[0012] In a preferred embodiment of this invention, an expansion block is fixedly connected to the bottom of the adjusting screw, and the expansion block is used to rotate the adjusting screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a first gear and a second gear, allows the user to rotate the drilling device when needed. Rotating the rod causes the first gear to rotate, which in turn drives the meshing second gear to rotate, thus rotating the drilling device. As the drilling device descends, the first gear descends along the trajectory of the rod, ensuring continuous meshing between the first and second gears. This solves the problem of the aforementioned devices where the drilling device is manually rotated to drill into the soil, and the user needs to gradually bend over to rotate it, leading to fatigue and difficulty in rotating the device due to changes in posture. This invention achieves a user-friendly design.

[0015] 2. By setting up a support component, after the user has adjusted the leveling frame, before rotating the flower rod, the sleeve is first rotated to the vertical position, and then the adjusting screw is rotated to move it from inside the sleeve to the outside until the adjusting screw contacts the ground. Then, through the cooperation of the sleeve and the adjusting screw, additional independent support is provided for the flower rod below, thereby preventing the leveling frame and drilling device from tipping over due to the pressure and torque of the user rotating the flower rod.

[0016] 3. By setting up a clamping plate, the clamping plate is fixed to the surface of the drilling device during the lifting and lowering process of the drilling device. The clamping plate is lifted and lowered together and pushes the first gear. As a result, the first gear and the second gear maintain a stable meshing connection during the transmission process, so that the rotational power of the flower rod is stably transmitted to the drilling device.

[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. 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.

[0022] As shown in Figures 1 to 3, the present invention provides a drilling device 2 for geological resource exploration, including a horizontal frame 1 and a drilling device 2. The surface of the drilling device 2 is threadedly connected to the inner wall of the horizontal frame 1. A perforated rod 3 is movably connected to the top left side of the horizontal frame 1 via a pin. A first gear 4 is slidably connected to the surface of the perforated rod 3. A second gear 5 is meshed with the right side of the first gear 4. The inner wall of the second gear 5 is fixedly connected to the top of the surface of the drilling device 2. A support assembly 6 is movably connected to the top left side of the horizontal frame 1 via a pin.

[0023] Referring to Figure 1, the support assembly 6 includes a sleeve 61. The top right side of the sleeve 61 is movably connected to the top left side of the horizontal frame 1 via a pivot pin. An adjusting screw 62 is threadedly connected to the inner wall of the sleeve 61.

[0024] As a technical optimization of this utility model, by setting up the support component 6, after the user has adjusted the horizontal frame 1, before rotating the flower rod 3, the sleeve 61 is first rotated to the vertical position, and then the adjusting screw 62 is rotated to move it from inside the sleeve 61 outward until the adjusting screw 62 contacts the ground. Then, through the cooperation of the sleeve 61 and the adjusting screw 62, additional independent support is provided for the flower rod 3 below, thereby preventing the pressure and torque caused by the user rotating the flower rod 3 from causing the horizontal frame 1 and the drilling device 2 to tip over.

[0025] Referring to Figures 1 and 2, clamping plates 7 are provided on both sides of the second gear 5. The inner wall of the clamping plate 7 is fixedly connected to the surface of the drilling device 2. The right sides of the first gear 4 are located between the inner sides of the clamping plates 7.

[0026] As a technical optimization of this utility model, by setting a clamping plate 7, during the lifting and lowering process of the drilling device 2, the clamping plate 7 is fixed on the surface of the drilling device 2 and lifts and lowers together, pushing the first gear 4. As a result, the first gear 4 and the second gear 5 always maintain a stable meshing connection during the transmission process, so that the rotational power of the flower rod 3 is stably transmitted to the drilling device 2.

[0027] Referring to Figure 1, a handwheel 8 is connected to the top of the flower stem 3, and the handwheel 8 is used to rotate the flower stem 3.

[0028] As a technical optimization of this utility model, by setting a handwheel 8, when the user needs to rotate the flower rod 3, the handwheel 8 can be used to apply a rotational force to the flower rod 3, thereby making the flower rod 3 rotate easily, and then realizing a series of subsequent transmissions, thereby improving the user's ease of operation.

[0029] Referring to Figure 2, the inner side of the clamping plate 7 is inlaid with balls 9. Both sides of the first gear 4 and the second gear 5 are in contact with the inner side of the balls 9. There are several balls 9 arranged in a ring and evenly distributed.

[0030] As a technical optimization of this utility model, by setting a ball bearing 9, the ball bearing 9 replaces the clamping plate 7 in contact with the first gear 4 and the second gear 5. When the first gear plate and the second gear plate rotate, the ball bearing 9 fits against them and rolls. In turn, the ball bearing 9 transforms the sliding friction between the clamping plate 7 and the first gear 4 and the second gear 5 into rolling friction, thereby reducing frictional resistance and making the meshing transmission of the first gear 4 and the second gear 5 smoother.

[0031] Referring to Figure 1, a half-cover 10 is fitted onto the surface of the first gear 4, and the inner wall of the half-cover 10 is slidably connected to the surface of the flower rod 3.

[0032] As a technical optimization of this utility model, by setting a half cover 10, when the first gear 4 moves up and down along the trajectory of the flower rod 3, the half cover 10 moves along with it. Thus, the half cover 10 blocks the side of the first gear that is closest to the user when the user rotates the flower rod 3, thereby preventing the user from being injured by the rotating first gear 4.

[0033] Referring to Figure 1, an expansion block 11 is fixedly connected to the bottom of the adjusting screw 62, and the expansion block 11 is used to rotate the adjusting screw 62.

[0034] As a technical optimization of this utility model, by setting up an expansion block 11, the expansion block 11 is used to replace the adjusting screw 62 in contact with the ground, thereby increasing its contact area with the ground and improving the support effect. At the same time, the expansion block 11 can provide a point for applying rotational force when the user rotates the adjusting screw 62.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to drill a hole in the ground to take samples from deep soil, first adjust the leveling frame 1 to make the drilling device 2 horizontal and vertical. Then, rotate the sleeve 61 to the vertical position, and then rotate the adjusting screw 62 to move it from inside the sleeve 61 outwards until the adjusting screw 62 contacts the ground. Through the cooperation of the sleeve 61 and the adjusting screw 62, additional independent support is provided below the flower rod 3. Then, the flower rod 3 can be rotated by the handwheel 8, causing the first gear 4 to rotate, which in turn drives the meshing second gear 5 to rotate. Then, the drilling device 2 starts to rotate and drill into the ground. At the same time, the clamping plate 7 rises and falls together, pushing the first gear 4 so that the first gear 4 descends along the trajectory of the flower rod 3. Thus, the first gear 4 and the second gear 5 maintain a stable meshing connection during the transmission process, so that the rotational power of the flower rod 3 is stably transmitted to the drilling device 2. Thus, during the process of the drilling device 2 descending into the ground, the user does not need to gradually bend over to match the height of the drilling device 2, thereby reducing the labor intensity. Finally, the user can use the drilling device 2 to extract the soil from the ground for resource exploration, thus having the advantage of being easy to use.

[0036] In summary, the drilling device 2 for geological resource exploration, by setting a first gear 4 and a second gear 5, allows the user to rotate the drilling device 2 by rotating the stud 3, causing the first gear 4 to rotate, which in turn drives the meshing second gear 5 to rotate, thus rotating the drilling device 2. As the drilling device 2 descends, the first gear 4 descends along the trajectory of the stud 3, ensuring continuous meshing between the first gear 4 and the second gear 5. This solves the problem of the drilling device in the above-mentioned equipment, which relies on manual rotation to drill into the soil. Furthermore, as the drilling device descends deeper into the soil, the user needs to gradually bend over to rotate it, which is not only tiring but also makes it difficult to rotate the drilling device due to changes in body posture.
