[0035] As Figures 1-7 shown:

[0036] A soil sampling device for geological exploration includes a mounting cover 101 and an annular seat 102 arranged below the mounting cover 101. A plurality of groups of connecting pieces 104 are fixed between the mounting cover 101 and the annular seat 102. A sampling cylinder 105 is arranged inside the mounting cover 101, and symmetrically arranged second electric push rods 106 are fixedly installed between the sampling cylinder 105 and the mounting cover 101;

[0037] At the open bottom of the annular seat 102, a fixed chassis 103 is fixedly installed, and a circular hole adapted to the outer diameter of the sampling cylinder 105 is opened at the center of the fixed chassis 103;

[0038] A storage mechanism 2 for automatically storing the samples taken out by the sampling cylinder 105 is installed between the mounting cover 101 and the annular seat 102;

[0039] The storage mechanism 2 includes an annular disc 201 fixed inside the annular seat 102 through a plurality of groups of support rods and a plurality of storage barrels 202 arranged in an annular equidistant manner above the annular disc 201. A sampling tube 206 is placed inside the storage barrel 202;

[0040] The surface of the storage bucket 202 is fixed with an L-shaped block 203. A rectangular opening is provided at a position on the edge surface of the annular disk 201 close to the storage bucket 202, and symmetrically arranged limit pins 204 are provided in the rectangular opening. The L-shaped block 203 slides on the corresponding limit pins 204 through the through holes opened. A spring 205 is wound around the surface of the limit pin 204, and both ends of the spring 205 are fixedly connected to the L-shaped block 203 and the limit pin 204 respectively. A support ring 210 is fixed to the inner side wall of the mounting cover 101. The support ring 210 is rotatably connected to an internal gear disk 209 through a bearing. A motor 207 is fixedly installed on the inner side wall of the mounting cover 101 through a mounting plate. A spur gear 208 is fixed to the output end of the motor 207. The spur gear 208 meshes with the internal gear disk 209. A connecting plate 211 is fixed to the bottom surface of the internal gear disk 209. A first electric push rod 212 is fixedly installed on the surface of the connecting plate 211;

[0041] The outer surface of the sampling tube 206 is adapted to the inner side wall of the storage bucket 202, and the inner diameter of the sampling tube 206 is larger than the outer diameter of the sampling cylinder 105;

[0042] The distance between adjacent connecting pieces 104 is larger than the outer diameter of the sampling tube 206, and the distance between the mounting cover 101 and the annular seat 102 is larger than the height of the sampling tube 206;

[0043] A discharging mechanism 3 for discharging the sample is installed on the sampling cylinder 105;

[0044] The discharging mechanism 3 includes a push plate 301 arranged inside the sampling cylinder 105 and a U-shaped rod 302 fixed to the upper surface of the push plate 301. A plurality of multi-section telescopic rods 303 arranged symmetrically are fixed between the U-shaped rod 302 and the mounting cover 101. A resisting rod 304 is fixed to the inner side wall of the mounting cover 101, and the corner part of the resisting rod 304 corresponds to the top end of the U-shaped rod 302;

[0045] A moving hole adapted to the push plate 301 is provided at the top of the sampling cylinder 105. The push plate 301 and the sampling cylinder 105 are slidably connected through this moving hole. The top end of the push plate 301 penetrates through the sampling cylinder 105 and extends to the outside of the sampling cylinder 105;

[0046] A sealing gasket is fixed to the outer surface of the push plate 301, and the sealing gasket is used to increase the sealing performance between the push plate 301 and the sampling cylinder 105;

[0047] A laser rangefinder 107 is fixedly installed at the top of the sampling cylinder 105. A control display panel 108 is fixedly installed on the outside of the mounting cover 101 through the mounting holes opened. The laser rangefinder 107 and the control display panel 108 are electrically connected;

[0048] At the top of the installation cover 101, symmetrically arranged grip rings 109 are fixedly installed. Fixing pins 111 are provided at both ends of the annular seat 102. A rope 110 is installed between the fixing pin 111 and the corresponding grip ring 109.

[0049] In this implementation: When using this geological exploration soil sampling device, first place this device in the area to be sampled, so that the fixed chassis 103 is in horizontal contact with the ground.

[0050] Two groups of grip rings 109 are provided at the top of the installation cover 101. The staff holds the grip rings 109, which facilitates the handling of this device. At the same time, the fixing pin 111 can be inserted into the soil in the sampling area, and a rope 110 is tied between the fixing pin 111 and the grip ring 109 to stably connect the installation cover 101 to the ground.

[0051] Set specific sampling parameters through the control display panel 108, such as the depth of multiple separate samplings.

[0052] By starting the second electric push rod 106, the sampling cylinder 105 is driven to insert into the soil. During the process of the sampling cylinder 105 inserting into the soil, the sampled soil continuously enters the sampling cylinder 105. At this time, the push plate 301 inside the sampling cylinder 105 is continuously pushed up by the soil. As the push plate 301 moves upward, the U-shaped rod 302 is driven to move upward, causing the U-shaped rod 302 to slide on the top of the sampling cylinder 105 and compress the multi-section telescopic rod 303. The distance projected by the laser rangefinder 107 on the top of the installation cover 101 is the depth of the sampling cylinder 105 inserted into the soil. When the sampling cylinder 105 is inserted to the specified depth in the soil, then control the second electric push rod 106 to reset and extract the sampled soil.

[0053] During the process of the sampling cylinder 105 being extracted from the soil, due to the setting of the fixed chassis 103, since the circular hole opened at the center of the fixed chassis 103 is adapted to the outer surface of the sampling cylinder 105, the soil carried on the outer surface of the sampling cylinder 105 can pass through the fixed chassis 103 to scrape off the soil on the surface of the sampling cylinder 105, so that the outer surface of the sampling cylinder 105 does not carry soil, avoiding contamination of soil sampling during multiple samplings and improving the use effect of this structure.

[0054] As the bottom of the sampling tube 105 moves to the top of the storage barrel 202, when the distance projected by the laser rangefinder 107 on the top of the mounting cover 101 reaches the specified distance, the laser rangefinder 107 sends a signal to the controller, and the controller controls the motor 207 to operate, and drives the spur gear 208 to rotate, and the spur gear 208 is meshed with the inner gear plate 209, thereby driving the inner gear plate 209 to rotate on the support ring 210, until the support ring 210 drives the connecting plate 211 and the first electric push rod 212 to move synchronously, until the first electric push rod 212 is moved. The electric push rod 212 corresponds to a group of storage barrels 202, stops the operation of the motor 207, starts the first electric push rod 212 on the connecting plate 211, and drives the storage barrel 202 to move by extending the first electric push rod 212, so that the storage barrel 202 slides on the surface of the limit pin 204 through the L-shaped block 203, and the L-shaped block 203 drives the spring 205 to stretch until the surface of the L-shaped block 203 contacts the inner side wall of the rectangular opening of the annular disk 201, and at this time the storage barrel 202 and the annular disk 201 correspond concentrically;

[0055] At this time, the U-shaped blocking end of the U-shaped rod 302 is close to the abutment rod 304, and when the second electric push rod 106 is started and continues to drive the sampling tube 105 to move upward, the soil inside the sampling tube 105 drives the push plate 301 to move upward synchronously. Since the abutment rod 304 blocks the top of the U-shaped rod 302, the push plate 301 will not move upward. In this process, as the sampling tube 105 continues to move upward, the push plate 301 can push out the soil inside the sampling tube 105 and discharge the soil inside the sampling tube 105 into the sampling tube 206 of the storage bucket 202 for storage.

[0056] The outer surface of the push plate 301 is provided with a sealing gasket, and the sealing gasket is made of silicone, which is used to increase the sealing between the push plate 301 and the sampling tube 105, so that when the push plate 301 pushes the soil, the soil inside the sampling tube 105 can be pushed out more cleanly;

[0057] The spring 205 is set so that when the soil is stored in the sampling tube 206, the first electric push rod 212 releases the push on the storage barrel 202. The spring 205 in the stretched state can drive the storage barrel 202 to drive the L-shaped block 203 to slide on the limit pin 204 to reset the position.

[0058] This device can continue the sampling operation, and the soil samples taken each time can be placed in the corresponding sampling tube 206;

[0059] The spacing between adjacent connecting pieces 104 is greater than the outer diameter of the sampling tube 206, and the spacing between the mounting cover 101 and the annular seat 102 is greater than the height of the sampling tube 206. Thus, the sampling tube 206 can be taken out from the storage barrel 202 through the opening formed between the connecting pieces 104, preparing for subsequent soil detection.

[0060] This solution can automatically complete soil sampling at different depths and directly distribute the soil to the corresponding sampling boxes, reducing the steps of manual soil transfer, simplifying the operation process. The automated sampling process greatly improves the sampling efficiency, saves time and labor. Moreover, the fixed chassis 103 can scrape off the soil carried by the sampling cylinder 105, preventing external soil pollution. The soil carried outside the sampling cylinder 105 will not contaminate the internal sample, ensuring the purity of the sample and improving the use effect of this structure to meet the actual use requirements.

[0061] It should be noted that: a storage battery is fixedly installed on the inner side wall of the mounting cover 101 of this product to supply power to the second electric push rod 106, the first electric push rod 212 and the motor 207. A control module is also provided in the solution, and the control module is arranged on the mounting cover 101. When in use, each electrical equipment can be started to operate through the electric control cabinet. The power connection method of each electrical equipment is an existing mature technology and is well-known to those skilled in the art, so no redundant description will be made here.

[0062] The present invention also provides a sampling method for a soil sampling device for geological exploration, including the following steps:

[0063] S1. Place the sampling device in the area to be sampled;

[0064] S2. Fix two groups of fixing pins 111 into the soil, and respectively tie and wind the two ends of the rope 110 around the fixing pins 111 and the grip ring 109;

[0065] S3. Set the sampling parameters on the control display panel 108 and start the sampling operation;

[0066] S4. Take out the sampling tube 206 and detect the soil sample.

[0067] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.
