Description

Technical Field

[0001] This invention relates to the field of rock sampling equipment technology, and more particularly to a geological field groove sampling device. Background Technology

[0002] Geological field trenching sampling equipment is a general term for specialized tools and equipment used in geological and mineral exploration to carve continuous and representative rock samples from the surface of geological bodies such as outcrops, trenches, and tunnels in accordance with standardized specifications and requirements. It includes both traditional simple manual tools such as geological hammers and chisels, as well as various mechanized trenching tools such as handheld and rail-mounted types. Its core function is to accurately and systematically complete the collection of geological samples. The main purpose of conducting geological field trenching sampling is to obtain spatially representative rock and ore samples, and then conduct laboratory analysis and testing to determine key indicators such as the chemical composition, mineral composition, grade, and resource reserves of ore bodies or geological bodies. This provides real and reliable basic data support for mineral resource exploration and evaluation, reserve estimation, mining planning, and geological scientific research.

[0003] For example, patent document CN114544220B discloses a geological tunnel grooving sampling device. This device uses a combination of two cutting drill bits and diamond cutting wire to first cut two parallel grooves, and then uses the diamond cutting wire to repeatedly cut the middle rock mass, obtaining a complete rock sample in one go. This avoids the problem of rock fragmentation and breakage in traditional sampling, which is beneficial for subsequent geological exploration and research. Simultaneously, it is equipped with a sliding support platform and telescopic support rod, eliminating the need for manual operation throughout the process, significantly saving manpower. By adjusting the length of the telescopic support rod and the coordination of the arc-shaped sliding sleeve, it can adapt to geological bodies of different heights and inclination angles, making it more flexible in application scenarios. A built-in water pump and flushing cooling pipe can cool the cutting drill bits and diamond cutting wire, preventing overheating damage to components caused by high-speed cutting. The cutting drill bits are detachably connected to the gear connecting seat via a rectangular insert shaft, facilitating the replacement of worn parts. Operating handles are located on both sides of the machine body for easy manual adjustment of the position. The sliding support platform is equipped with protective inserts that can fit tightly against the rock mass to block the cut sample strips, preventing them from coming off or breaking due to vibration or gravity, and further ensuring the integrity of the sample strips.

[0004] However, in practical use, the above-mentioned device still has certain shortcomings: 1) Poor flexibility for long-distance sampling: It relies on a fixed-length sliding support platform (1.2m in the example). If the mine tunnel is long, it is necessary to disassemble and adjust the position of the support multiple times, which is cumbersome and inefficient; 2) Complex secondary cutting operation: If it is necessary to deepen the cutting depth or adjust the cutting specifications, it is necessary to disassemble and replace the cutting parts or adjust the support parameters. It is not possible to quickly achieve secondary cutting, and the convenience of adapting to different sampling needs is insufficient; 3) Lack of debris cleaning mechanism: Gravel and dust in the mine tunnel are easy to accumulate on the sliding support platform or track. The lack of a special cleaning device may affect the sliding accuracy of the machine body or even cause the device to jam; 4) Insufficient convenience of movement and installation: Although the combination of the sliding support platform and the telescopic support rod can adjust the angle, the overall disassembly, transportation and installation process is cumbersome, especially when moving in the mine tunnel with complex terrain, the flexibility is poor. Summary of the Invention

[0005] This invention provides a geological field groove sampling device to solve the technical problems of poor long-distance adjustment effect, inability to quickly perform secondary cutting, and inconvenience in cleaning debris in existing groove sampling devices.

[0006] To solve the above problems, the geological field groove sampling equipment provided by this invention adopts the following technical solution: A geological field groove sampling device includes: Support rails are laid on the sampling surface inside the mine to limit the cutting stroke; A movable cutting assembly, guided on the support rail, is used to move along the support rail within a defined cutting stroke. The movable cutting assembly includes cutting pieces of at least two sizes to accommodate different cutting needs. An unloading assembly, which is arranged on the movable cutting assembly, is used to clean up debris located on the support guide rail as the movable cutting assembly moves; The support guide rail is also provided with a discharge channel, which is used to discharge the debris swept by the discharge assembly.

[0007] The advantages of the above solution are as follows: the support rail can be directly laid on the sampling surface inside the mine. Laying it defines the cutting stroke; regardless of the depth or length of the mine, the rail only needs to be laid once, and the mobile cutting component can automatically travel along the rail for sampling without repeated adjustments to the device position. The mobile cutting component integrates at least two sizes of cutting parts, eliminating the need to disassemble or replace core components. It can quickly switch according to sampling needs (such as different cutting depths and groove widths), reducing the complexity of secondary cutting. The unloading component moves synchronously with the mobile cutting component, cleaning up debris such as gravel and dust on the support rail in real time. This debris is quickly discharged through the unloading channel of the support rail, requiring no additional power drive; the cleaning is achieved using the walking power of the mobile component. The entire device has a high degree of integration, with no redundant or complex structures, making disassembly, assembly, and transportation easy. The support rail can be laid in sections and fixed with bolts, adapting to narrow mines and rugged terrain.

[0008] Furthermore, the support rail includes a base plate and a bearing plate. The base plate is arranged vertically for mounting on the sampling surface of the mine shaft; the bearing plate is arranged horizontally for supporting the movable cutting assembly.

[0009] The advantages of the above solution are: the substrate is vertically attached to the sampling surface of the mine, which provides strong stability after fixing and avoids the guide rail from shifting due to cutting vibration; the bearing plate supports the moving cutting components horizontally, providing a flat and stable sliding support surface.

[0010] Furthermore, the movable cutting assembly includes a movable base, with the cutting element arranged on the upper end of the movable base and the lower end of the movable base slidably arranged on the support plate, the support plate having a slide rail for placing the movable base.

[0011] Furthermore, the movable base is defined to move from back to front on the support plate, and the movable base and / or its rear end have an inclined plate that slopes downwards. The inclined plate is used to sweep debris into the unloading channel during the back-and-forth movement of the movable base, and the inclined plate constitutes the unloading assembly.

[0012] The advantages of the above solution are: the unloading component is integrated into the mobile base and / or rear end, and the debris is guided to move towards the unloading channel by gravity using the top-down inclined structure, without the need for an additional power source, and the structure is simple and reliable; the inclined plate moves synchronously with the mobile base, realizing cleaning while walking, with high cleaning efficiency and no dead corners, avoiding the accumulation of debris at both ends of the guide rail; at the same time, it does not increase the size and weight of the device, ensuring the portability of the equipment and adapting to the operation in the narrow space of the mine.

[0013] Furthermore, the supporting plate has multiple through holes extending through the plate thickness in its extending direction, and these through holes constitute the unloading channel.

[0014] Furthermore, the cutting component includes two sets of cutting disc structures that can move left and right to approach or move away from the sampling surface of the mine. Each set of cutting disc structures has a cutting disc, and the cutting discs in the two sets of cutting disc structures are of different sizes, so as to select the appropriate cutting disc structure for sampling according to actual needs.

[0015] The advantages of the above solution are: the left-right movable design allows for adjustment of the distance between the cutting disc and the sampling surface of the mine, adapting to different thicknesses of ore bodies or sampling trench width requirements; the two sets of cutting discs of different sizes can be switched without disassembly, and when performing secondary cutting or adjusting sampling specifications, only the position of the cutting disc structure needs to be moved; at the same time, the two sets of cutting discs can be used individually or simultaneously, which can meet the needs of single cutting, secondary deepening, and multi-specification sampling, improving the versatility of the equipment.

[0016] Furthermore, each set of cutting discs includes a bracket, a blade housing, and two cutting discs. The bracket is guided and arranged on the movable base, and the blade housing is mounted on the bracket. The blade housing contains a motor arranged vertically. The two cutting discs are arranged at intervals in the vertical direction and are both driven to rotate by the motor.

[0017] The beneficial effects of the above scheme are: each set of cutting discs consists of two cutting discs arranged vertically and horizontally, which are driven by a motor to rotate synchronously. Two parallel grooves can be formed in one cut, eliminating the need for multiple cuts and doubling the sampling efficiency.

[0018] Furthermore, the movable base has multiple adjustment holes that extend in the left-right direction. The bracket is fixed in the adjustment holes by bolts, and when different cutting disc structures are required, the corresponding cutting disc structure can be installed by selecting the adjustment holes at different positions.

[0019] The advantages of the above solution are: the adjustment hole extends in the left and right direction, which can flexibly adjust the left and right position of the cutting disc structure to adapt to the sampling needs of different distances (such as ore bodies of different widths); the bolt fixing method is convenient to install and disassemble; when switching the cutting disc structure or adjusting the position, no complicated tools are required, and the operation is simple and efficient; at the same time, the bolt fixing has strong stability, and the cutting disc structure will not shift during the cutting process, ensuring cutting accuracy and further reducing the operating threshold for field operations.

[0020] Furthermore, the bearing plate is an L-shaped plate, with the open side of the L-shaped plate facing the sampling surface of the mine. The vertical plate of the L-shaped plate has a horizontally extending limiting plate. The side of the movable base also has traveling wheels that guide and cooperate with the upper and lower sides of the limiting plate to improve the stability of the movable base moving back and forth.

[0021] The beneficial effects of the above solution are: the limiting plate on the vertical plate and the traveling wheels of the moving base cooperate in a two-way guiding manner, which can effectively prevent the moving base from tipping over due to uneven cutting gravity and mine tilt. The cooperation between the traveling wheels and the limiting plate reduces sliding resistance and improves the moving positioning accuracy, ensuring that the cutting groove is straight and regular, which is especially suitable for inclined mines or high-intensity cutting operations.

[0022] Furthermore, a reinforcing rib is provided between the substrate and the support plate to improve the strength of the support rail.

[0023] The beneficial effects of the above solution are: the reinforcing ribs significantly improve the overall strength and deformation resistance of the support rail, and the vibration and impact generated during the cutting process will not cause the rail to bend or shift, ensuring the stability of long-term use; the reinforcing ribs do not affect the disassembly and portability of the rail, while dispersing the load-bearing pressure of the load-bearing plate, avoiding deformation of the load-bearing plate due to the weight of the moving cutting components, extending the service life of the rail, and making it suitable for high-intensity operation scenarios such as hard rocks and long-distance continuous sampling.

[0024] The beneficial effects of the geological field groove sampling device provided by the present invention are as follows: The geological field groove sampling device of the present invention solves the problems of cumbersome long-distance sampling, complicated secondary cutting operation, easy jamming of debris, and inconvenient installation and movement of the prior art by integrating the supporting guide rail, the moving cutting component of multi-size cutting parts, the follow-up unloading component and the unloading channel. The support rails can be laid as needed to adapt to mine shafts of different lengths. Combined with the multi-size cutting parts and adjustable installation design of the mobile cutting assembly, it can quickly adapt to different cutting depths and groove widths without replacing core components, greatly improving sampling flexibility and efficiency. The unloading assembly cleans synchronously with the mobile cutting assembly, and debris is discharged immediately through the unloading channel, ensuring the stability of equipment operation and cutting accuracy. In addition, the structural reinforcement design of the L-shaped bearing plate, limiting components, and reinforcing ribs not only improves the overall rigidity and operational safety of the equipment, but also simplifies the disassembly and transportation process, adapting to complex mine terrain and high-intensity sampling scenarios. Ultimately, it achieves synergistic optimization of sampling efficiency, sample quality, and ease of operation, providing more reliable and efficient technical support for geological and mineral exploration.

[0025] In summary, the entire device solves the technical problems of poor long-distance adjustment effect, inability to quickly perform secondary cutting, and inconvenience in cleaning debris in existing groove sampling devices. Attached Figure Description

[0028] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0029] Embodiments of the geological field groove sampling equipment provided by the present invention: like Figures 1 to 4 As shown, the geological field grooving sampling equipment includes a support rail 1, a moving cutting assembly, and a discharge assembly. The support rail 1 is laid on the sampling surface inside the mine shaft to limit the cutting stroke. The moving cutting assembly is guided and arranged on the support rail 1 to move along the support rail 1 within the limited cutting stroke. The moving cutting assembly includes at least two sizes of cutting pieces to adapt to different cutting needs. The discharge assembly is arranged on the moving cutting assembly to clean up debris located on the support rail 1 as the moving cutting assembly moves. The support rail 1 is also provided with a discharge channel for discharging the debris cleaned up by the discharge assembly.

[0030] Specifically, such as Figure 1As shown, the support rail 1 includes a base plate 2 and a support plate 3. The base plate 2 is arranged vertically for mounting on the sampling surface of the mine shaft; the support plate 3 is arranged horizontally for supporting the movable cutting assembly. The base plate 2 is vertically fitted to the sampling surface of the mine shaft, providing strong stability after fixing and preventing the guide rail from shifting due to cutting vibration; the support plate 3 horizontally supports the movable cutting assembly, providing a flat and stable sliding support surface. In actual fixing, the base plate 2 is fixed to the sampling surface of the mine shaft with bolts.

[0031] like Figure 1 and Figure 2 As shown, the movable cutting assembly includes a movable base 4, with the cutting component arranged on the upper end of the movable base 4, and the lower end of the movable base 4 slidably arranged on the support plate 3. The support plate 3 has a slide rail 5 for placing the movable base 4. A stepper motor (not shown in the figure) is arranged inside the movable base 4 to provide power. The stepper motor providing linear driving force is prior art and will not be described in detail here.

[0032] like Figures 1 to 4 As shown, the movable base 4 is defined to move from back to front on the support plate 3. The movable base 4 and / or the rear end have an inclined plate 6 that slopes downward from top to bottom. The inclined plate 6 is used to sweep debris into the unloading channel during the back-and-forth movement of the movable base 4. The inclined plate 6 constitutes the unloading assembly.

[0033] The unloading assembly is integrated into the mobile base 4 and / or the rear end. Utilizing the top-down inclined structure, it guides the debris to move towards the unloading channel by gravity, requiring no additional power source and featuring a simple and reliable structure. The inclined plate 6 moves synchronously with the mobile base 4, enabling cleaning while moving. This results in high cleaning efficiency and no blind spots, preventing debris from accumulating at both ends of the guide rail. At the same time, it does not increase the size and weight of the device, ensuring portability and making it suitable for operation in confined spaces in mines.

[0034] Debris and debris can be swept away by moving the movable base 4 back and forth. In this embodiment, the movable base 4 has inclined plates 6 at both the front and rear ends. In other embodiments, the inclined plates 6 may be arranged only at the front or rear end of the movable base 4.

[0035] In this embodiment, as Figures 1 to 4 As shown, the supporting plate 3 has multiple through holes 7 extending through the plate thickness in its extending direction, and these through holes 7 constitute the unloading channel. In other embodiments, the orientation of the through holes 7 may not be straight up and down, but may extend at an angle.

[0036] like Figure 2 and Figure 3As shown, the cutting component includes two sets of cutting disc structures 8 that can move left and right to approach or move away from the sampling surface of the mine shaft. Each set of cutting disc structures 8 has a cutting disc 9. The cutting discs 9 in the two sets of cutting disc structures 8 are of different sizes, so that the appropriate cutting disc structure 8 can be selected for sampling according to actual needs. The left and right movable design allows adjustment of the distance between the cutting disc 9 and the sampling surface of the mine shaft, adapting to different thicknesses of ore bodies or sampling groove width requirements. The two sets of cutting discs 9 of different sizes can be switched without disassembly. When performing secondary cutting or adjusting the sampling specifications, only the position of the cutting disc structure 8 needs to be moved. At the same time, the two sets of cutting disc structures can be used individually or simultaneously, which can realize the needs of single cutting, secondary deepening, and multi-specification sampling, improving the versatility of the equipment.

[0037] In this embodiment, each cutting disc structure 8 includes a support 10, a blade housing 11, and two cutting discs 9. The support 10 is guided and arranged on the movable base 4, and the blade housing 11 is mounted on the support 10. The blade housing 11 contains a vertically arranged motor 15. The two cutting discs 9 are spaced apart in the vertical direction and are both driven to rotate by the motor 15. Each cutting disc structure 8 includes two vertically arranged cutting discs 9 that are driven to rotate synchronously by the motor 15. Two parallel grooves can be formed in one cut, eliminating the need for multiple cuts and doubling the sampling efficiency.

[0038] In this embodiment, the movable base 4 has multiple adjustment holes (not shown in the figure) extending in the left-right direction. The bracket 10 is fixed in the adjustment holes with bolts. When different cutting disc structures 8 are needed, the corresponding cutting disc structure 8 is installed by selecting different adjustment holes. The adjustment holes extend in the left-right direction, allowing for flexible adjustment of the left and right position of the cutting disc structure 8 to adapt to sampling requirements of different distances (such as ore bodies of different widths). The bolt fixing method is convenient for disassembly and assembly. Switching the cutting disc structure 8 or adjusting its position does not require complex tools, making the operation simple and efficient. At the same time, the bolt fixing provides strong stability, ensuring that the cutting disc structure 8 will not shift during the cutting process, thus guaranteeing cutting accuracy and further reducing the operational threshold for field operations.

[0039] In other embodiments, a cylinder can be directly installed on the movable base 4, with the output end of the cylinder connected to the bracket 10 of the two cutting disc structures 8. The position of each cutting disc structure 8 can be adjusted by the horizontal movement of the cylinder output end.

[0040] In this embodiment, the support plate 3 is an L-shaped plate, with the open side of the L-shaped plate facing the sampling surface of the mine. The vertical plate of the L-shaped plate has a horizontally extending limiting plate 12. The side of the movable base 4 also has traveling wheels 13 that guide and cooperate with the upper and lower sides of the limiting plate 12 to improve the stability of the movable base 4 in moving forward and backward. The limiting plate 12 on the vertical plate and the traveling wheels 13 of the movable base 4 cooperate in a bidirectional vertical guidance manner, which can effectively prevent the movable base 4 from tipping over due to uneven cutting gravity or mine inclination. The cooperation between the traveling wheels 13 and the limiting plate 12 reduces sliding resistance and improves the moving positioning accuracy, ensuring that the cutting groove is straight and regular, which is especially suitable for inclined mines or high-intensity cutting operations.

[0041] Finally, in this embodiment, a reinforcing rib 14 is also provided between the substrate 2 and the support plate 3 to improve the strength of the support rail 1. The reinforcing rib 14 significantly improves the overall strength and deformation resistance of the support rail 1. The vibration and impact generated during the cutting process will not cause the rail to bend or shift, ensuring long-term stability. The reinforcing rib 14 does not affect the disassembly and portability of the rail, while dispersing the load-bearing pressure of the support plate 3, avoiding deformation of the support plate 3 due to the weight of the moving cutting components, extending the service life of the rail, and adapting to high-intensity operation scenarios such as hard rocks and long-distance continuous sampling.

[0042] like Figure 5 As shown, in the second embodiment, the left side of the support plate 3 can also be equipped with support rods 16 to improve the stability of the entire device during operation. Multiple support rods 16 are arranged at intervals along the length of the support guide rail 1. The support rods 16 are flat at the top and pointed at the bottom, with their lower ends able to insert into the ground layer at their location, providing oblique support to the support plate 3. Figure 6 As shown, the support rod 16 is composed of multiple single rods 161. One end of each single rod 161 has a threaded hole, and the other end has a threaded section 162. The single rods 161 are connected by threads, which makes assembly convenient and easy to store.

[0043] like Figure 7 As shown, to further facilitate transportation, the substrate 2 and the support plate 3 can also be rotatably connected by the pivot 18. When in use, the two are unfolded and the substrate 2 is fixed on the sampling surface inside the mine. At this time, the two ends of the reinforcing rib 14 are fixed to the substrate 2 and the support plate 3 respectively by bolts 17. When storing, the reinforcing rib 14 can be removed directly, and then the substrate 2 and the support plate 3 can be folded.

[0044] The working principle of the geological field groove sampling equipment provided by this invention is as follows: When in use, the base plate 2 of the supporting guide rail 1 is first vertically fixed on the sampling surface inside the mine. The bearing plate 3 provides horizontal support, and the overall strength is improved by the reinforcing rib plate 14. The movable base 4 is slidably arranged on the bearing plate 3 via the slide rail 5. The walking wheels 13 on its side cooperate with the limiting plate 12 on the vertical plate of the bearing plate 3 (L-shaped plate) to ensure the stability of movement. The sampling depth and groove width are required. The left and right positions of the two sets of cutting disc structures 8 of different sizes are adjusted by adjusting the adjustment holes on the movable base 4 or the support plate 3. The bracket 10 is fixed with bolts. Then, the motor 15 arranged vertically inside the cutter housing 11 is started to drive the two cutting discs 9 of each set of cutting disc structures 8 to rotate synchronously. The movable base 4 moves along the support guide rail 1 within the limited cutting stroke. The cutting disc 9 cuts two parallel grooves at once. If it is necessary to deepen or adjust the specifications, the cutting disc structure 8 of another size can be switched directly without replacing the core components. During the forward and backward movement of the movable base 4, the inclined plate 6 (unloading component) at its front end and / or rear end simultaneously cleans the gravel, dust and other debris on the support guide rail 1. The debris is discharged immediately through the multiple through holes 7 (unloading channels) in the extension direction of the support plate 3 to avoid affecting the movement accuracy or causing the device to jam. The entire process realizes accurate, efficient and convenient groove sampling operation.

[0045] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0046] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
