[0002] Mine geological survey refers to a technical means of detailed investigation, analysis and evaluation of the geological environment of mines in order to ensure the safe production of mines and the rational use of mineral resources during the mining process. In the mining geological exploration work, accurate acquisition of geological samples is crucial to understanding the geological structure, mineral distribution and resource reserves of the mine. Through detailed geological exploration of the mining area, the basic information such as the geological structure, ore body morphology, ore grade, etc. of the mine can be understood to provide a scientific basis for the mining of the mine. In the process of geological exploration, one of the important items is geological sampling, which requires the study of minerals and other components in the geology to provide the necessary technical means and accurate data for the later mining needs. In the sampling process, sampling devices are needed to assist in sampling.

[0003] When measuring the geology of a mine, an exploration sampling device is needed. When sampling a mine, it is often necessary to adjust the sampling angle of the mine according to the terrain.

[0034] The connecting rod 202 forms a lifting structure with the fixed inner ring 104 through the pressure rod 103. The connecting rod 202 and the fixed inner ring 104 are both arranged inside the fixed outer ring 2. The L-shaped plates 204 are symmetrically distributed on both sides of the dual-axis motor 203. The stabilizing frame 205 is a hollow cube. The stabilizing frame 205 is rotatably connected to the inner wall of the bottom end of the L-shaped plate 204. The rotating rod 206 and the L-shaped plate 204 are staggered. The outer end of the rotating rod 206 is rotatably connected to the stabilizing frame 205. The inner end of the rotating rod 206 is snap-connected to the outer wall of the micro motor 207. The micro motor 207 is rotatably connected to the inside of the stabilizing frame 205 through the rotating rod 206. The micro motor 207 is arranged at the bottom of the dual-axis motor 203 through the stabilizing frame 205. The connecting flange 208 is tilted downward on one side, and the top of one side of the connecting flange 208 is rotatably connected to At the bottom of the dual-axis motor 203, the side of the connecting flange 208 tilted downward is rotatably connected to the top of the micro motor 207, the connecting flange 208 is connected between the dual-axis motor 203 and the micro motor 207, the inclination angle of the dual-axis motor 203 is set parallel to the inclination angle of the micro motor 207, the sampling end 210 passes through the inner wall of the drill rod 209 and is rotatably connected to the micro motor 207, the sampling end 210 is set in a threaded shape, the sampling end 210 forms a lifting structure between the micro motor 207 and the drill rod 209, the retaining ring 212 is fixed to the top outer side of the drill bit tip 211, the retaining ring 212 and the bottom outer wall of the drill rod 209 are snap-fitted, the drill bit tip 211 and the sampling end 210 form a rotating structure with the stabilizing frame 205 through the cooperation between the micro motor 207, the connecting flange 208 and the dual-axis motor 203.

[0035] When the device is working, the staff places the entire device at the mining geological position where sampling is required, and fixes the device through the limit tip 201 at the bottom of the clamped outer ring 2. At the same time, through the cooperation between the fixing frame 102 and the threaded rod 105, it is convenient for the operator to operate the pressure rod 103 to descend. After the pressure rod 103 descends inside the clamped inner ring 104, it drives the connecting rod 202 to gradually extend into the ground. When the connecting rod 202 reaches the position where sampling is required, the dual-axis motor 203 is started, and the output end of the dual-axis motor 203 drives the connecting flange 208 to start rotating;

[0036] Since one side of the connecting flange 208 is tilted downward, and the top of one side is rotatably connected to the bottom of the dual-axis motor 203, and the other side is rotatably connected to the top of the micro motor 207, the micro motor 207 is parallel to the tilt angle of the dual-axis motor 203. At the same time, the L-shaped plates 204 on both sides of the dual-axis motor 203 support the stabilizing frame 205 and the micro motor 207. After the micro motor 207 is started, it drives the drill rod 209 to rotate, and the drill tip 211 at the bottom of the drill rod 209 begins to drill into the geological layer of the mine.

The connecting flange 208 enables the micro motor 207 to rotate at the bottom of the dual-axis motor 203. When the connecting flange 208 rotates to a certain angle, the elastic force of the reset spring 402 will drive the limiter 403 to move downward along the outer surface of the fixed axis 401, so that the rotation angle of the connecting flange 208 can be limited by the cooperation between the limiter 403 and the connecting flange 208, and the directional angle of the micro motor 207 can be adjusted. When the micro motor 207 rotates, it is connected to the inside of the stabilizing frame 205 through the rotating rod 206. The sampling end 210 rotates under the drive of the micro motor 207, and the soil is attached to the inside through the spiral groove on the outer wall of the sampling end 210.

[0037] For example 2, please refer to Figure 1 , Figure 6 and Figure 7 .

[0038] A through groove 3 is provided on the outside of one side of the fixed outer ring 2, and a first limit plate 301 is movably connected to the inner surface of one end of the through groove 3, and a second limit plate 302 is movably connected to the inside of the first limit plate 301, and a limit groove 303 is provided on the outside of the second limit plate 302, and a collecting groove 304 is provided on the outside of one side of the limit groove 303. A connecting ring 305 is fixedly connected to the inner wall of one side of the fixed outer ring 2, and the connecting ring 305 is arranged on the outer side of the bottom end of the fixed inner ring 104, and a placement strip 306 is fixedly connected to the inner surface of the connecting ring 305, and a cleaning brush 307 is fixedly connected to the inner surface of the placement strip 306.

[0039] The through groove 3 and the collecting groove 304 are opened on the outer walls of both sides of the fixed outer ring 2, a corner of the outer wall of the first limit plate 301 is rotatably connected to the through groove 3, the second limit plate 302 is slidably connected to the inner surface of the first limit plate 301, the first limit plate 301 and the second limit plate 302 are set to be inclined downward at 15°, the collecting groove 304 is opened to fit the inclination of the first limit plate 301 and the second limit plate 302, the first limit plate 301 forms a rotating structure with the fixed outer ring 2 through the through groove 3, the collecting groove 304 and the through groove 3 are opened through the interior of the fixed outer ring 2, the cleaning brush 307 is fixed to the bottom of the fixed inner ring 104 through the connecting ring 305, the cleaning brush 307 is located on the inner surface of the placement strip 306 and is distributed in a ring shape, and the cleaning brush 307 is set to be soft.

[0040] When the sampling is completed, the operator makes the linkage rod 202 start to rise through the cooperation between the fixing frame 102 and the threaded rod 105, and the linkage rod 202 drives the dual-axis motor 203 at the bottom and the sampling end 210 to start rising. When the sampling end 210 is about to rise to the inside of the connecting ring 305, the staff rotates the first limit plate 301 from the through groove 3 on the outside of the fixed outer ring 2 to the inside of the fixed outer ring 2, and the second limit plate 302 slides inside the first limit plate 301, and at the same time, pushes the second limit plate 302 inside the first limit plate 301 from the outside to make it fully expanded. The expanded first limit plate 301 and the second limit plate 302 are engaged with the inner walls of the limit grooves 303 on both sides. At this time, the sampling end 210 continues to rise, and when the sampling end 210 passes through the inside of the connecting ring 305, the connecting ring The cleaning brush 307 distributed in an annular shape inside 305 scrapes the sampling end 210. Under the combined action of gravity and the cleaning brush 307, the soil inside the spiral groove of the sampling end 210 falls above the first limiting plate 301 and the second limiting plate 302 that are fully extended at the bottom. At this time, the soil slides along the inclined first limiting plate 301 and the second limiting plate 302 to the direction of the lower limiting groove 303. The limiting groove 303 is connected to the collecting groove 304 through and through. At this time, the staff collects the collected soil from the collecting groove 304. Since the cleaning brush 307 is made of soft material, it will not hinder the connecting rod 202 when it descends. After the collection is completed, the second limiting plate 302 is pushed back into the first limiting plate 301, and the first limiting plate 301 is rotated to be placed outside the fixed outer ring 2 to complete the collection.

[0041] Working principle: When the device is working, the staff places the entire device at the mining geological position where sampling is required, and fixes the device through the limit tip 201 at the bottom of the clamping outer ring 2. Through the cooperation between the threaded rod 105 and the fixing frame 102, when the double-axis motor 203 is running, the pressure rod 103 can be controlled to descend. After the pressure rod 103 descends inside the clamping inner ring 104, it drives the connecting rod 202 to gradually extend into the ground. When the connecting rod 202 reaches the position where sampling is required, the double-axis motor 203 is started, and the output end of the double-axis motor 203 drives the connecting flange 208 to start rotating;

[0042] Since one side of the connecting flange 208 is tilted downward, and the top of one side is rotatably connected to the bottom of the dual-axis motor 203, and the other side is rotatably connected to the top of the micro motor 207, the micro motor 207 is parallel to the tilt angle of the dual-axis motor 203, and can be adjusted to different angles according to the sampling environment, so that the device can be used for samples of different angles and terrains, such as rapid on-site adjustment of the sampling terrain, etc. At the same time, the L-shaped plates 204 on both sides of the dual-axis motor 203 support the stabilizing frame 205 and the micro motor 207. After the micro motor 207 is started, it drives the drill rod 209 to rotate, and the drill bit tip 211 at the bottom of the drill rod 209 begins to drill into the geological layer of the mine. As drilling proceeds, the sampling end 210 is driven by the micro motor 207 to perform lifting movements in the drill rod 209, gradually going deeper into the geological layer for sampling. The micro motor 207 is connected to the stabilizing frame 205 through the rotating rod 206 when rotating, and the stabilizing frame 205 is rotatably connected to the inner surface of the L-shaped plate 204 to ensure the stability of the micro motor 207 in an inclined state. The connecting flange 208 allows the micro motor 207 to rotate at the bottom of the dual-axis motor 203. The micro motor 207 is connected to the inside of the stabilizing frame 205 through the rotating rod 206 when rotating. The sampling end 210 is driven by the micro motor 207 to rotate, and the soil is attached to the inside through the spiral groove on the outer wall of the sampling end 210;

[0043] When the sampling is completed, the threaded rod 105 is controlled to rotate by the dual-axis motor 203, so that the connecting rod 202 starts to rise, and the connecting rod 202 drives the dual-axis motor 203 and the sampling end 210 at the bottom to start rising. When the sampling end 210 is about to rise to the inside of the connecting ring 305, the staff rotates the first limit plate 301 from the through groove 3 on the outside of the fixed outer ring 2 to the inside of the fixed outer ring 2, and the second limit plate 302 slides inside the first limit plate 301, and at the same time, the second limit plate 302 inside the first limit plate 301 is pushed from the outside to make it fully expanded. The expanded first limit plate 301 and the second limit plate 302 are engaged with each other on both sides. The inner wall of the limiting groove 303, at this time, the sampling end 210 continues to rise, and when the sampling end 210 passes through the inside of the connecting ring 305, the cleaning brush 307 distributed in an annular manner inside the connecting ring 305 scrapes the sampling end 210, and the soil inside the spiral groove of the sampling end 210 falls into the first limiting plate 301 and the second limiting plate 302 that are fully extended at the bottom under the combined action of gravity and the cleaning brush 307. At this time, the soil slides along the inclined first limiting plate 301 and the second limiting plate 302 to the direction of the limiting groove 303 at the lower position, and the limiting groove 303 is connected with the collecting groove 304 through and through. At this time, the staff collects the collected soil from the collecting groove 304;

[0044] Since the cleaning brush 307 is made of soft material, it will not cause any obstruction to the linkage rod 202 when it descends. After the collection is completed, the second limit plate 302 is pushed back into the first limit plate 301, and the first limit plate 301 is rotated to be placed outside the fixed outer ring 2 to complete the collection work.

[0045] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
