Description

A method for collecting soil samples using a geological exploration soil sampling device Technical Field

[0001] This invention belongs to the field of geological exploration technology, and specifically relates to a method for collecting soil samples using a geological exploration soil sampling device. Background Technology

[0002] Geological exploration involves investigating and exploring geology using various methods to determine suitable bearing strata, identify foundation types based on the bearing capacity of these strata, and calculate foundation parameters. It also includes the discovery of industrially significant mineral deposits during mineral prospecting, providing mineral reserves and geological data necessary for mine construction design to ascertain the quality and quantity of minerals and the technical conditions for their exploitation, as well as sampling studies for the remediation of soils contaminated with organic pollutants, radioactive sources, and heavy metals. Furthermore, it involves investigating the geological conditions of a specific area, including rocks, strata, structures, minerals, hydrology, and geomorphology. In geological exploration and soil pollution investigations, soil sampling and analysis are required. Current technologies, when sampling deep soil layers, use open sampling ports. During the sampling process, shallow soil easily mixes with deeper soil samples, affecting sampling accuracy. Existing controllable stratified sampling devices, due to their control structures, cannot extend the sampling length, limiting the sampling depth range. Summary of the Invention

[0003] The purpose of this invention is to provide a method for collecting soil samples in geological exploration, so as to solve the problem of limited sampling range of existing sampling equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A method for collecting soil samples using a geological exploration soil sampling device includes a horizontal fixing frame, with leveling mechanisms at both ends of the horizontal fixing frame and a sampling component mounted on the horizontal fixing frame;

[0006] The sampling assembly includes a mounting base horizontally mounted on the top surface of a horizontal fixed frame. A vertical rotating handle is rotatably mounted inside the mounting base. A rod is connected to the lower end of the rotating handle, and a sampling head is provided at the lower end of the rod.

[0007] The sampling head includes a soil drilling cone and a sampling cylinder. The soil drilling cone is located below the sampling cylinder, and a sliding rod is formed and connected to the upper end of the soil drilling cone along the axis. The sliding rod passes upward into the sampling cylinder and is slidably connected to the bottom of the sampling cylinder. Several sampling ports are evenly spaced on the side wall of the sampling cylinder. A sealing baffle is provided on the part of the sliding rod inside the sampling cylinder corresponding to each sampling port. When the top surface of the soil drilling cone is in close contact with the bottom surface of the sampling cylinder, the sliding rod abuts against the top of the sampling cylinder, and the sealing baffle blocks the sampling port. The sliding rod has a prismatic structure.

[0008] The working process and principle of the above structure are as follows:

[0009] In use, first place the horizontal fixing frame on the ground and adjust it to a horizontal state using the leveling mechanism. Then, connect the sampling head to the rod body and the rod body to the rotating handle. By rotating the handle, the sampling head rotates downward. When the sampling head drills downward, the soil cone is resisted by the soil, thus fitting tightly against the sampling tube. The sealing baffle blocks the sampling port, preventing shallow soil from entering the sampling port. After drilling to the expected depth, pull the sampling head upward. The soil cone separates from the sampling tube due to gravity. The sliding rod moves the sealing baffle downward, opening the sampling port. Soil enters the sampling tube from the sampling port and is sampled in layers. When a deeper drilling depth is required, the rod body can be extended to ensure the drilling depth, thereby enabling the understanding of the pollution of deep soil by organic pollutants, radioactive sources, and heavy metals.

[0010] Furthermore, several conical retaining skirts are respectively provided on the outer side of the sampling tube below each sampling port. The opening angle of the retaining skirts faces upward, and the taper of the retaining skirts is smaller the closer they are to the drilling cone.

[0011] The purpose of the retaining skirt is to facilitate better scraping of soil when the sampling tube is pulled out for sampling, so that the soil can enter the sampling port and be easily sampled. The tapered angle of the retaining skirt gradually decreases, which makes it easier for the sampling tube to move downwards during drilling.

[0012] Furthermore, a sampling baffle is provided below each sampling port inside the sampling cylinder. The sampling baffle is coaxially arranged with the sampling cylinder and is horizontally and detachably fixed inside the sampling cylinder.

[0013] The sampling baffle not only limits the sealing baffle but also creates a space to hold the sampled soil.

[0014] Furthermore, the rod body includes several detachable extension rods connected in sequence. One end of each extension rod has an internal threaded hole along its axis, and the other end of each extension rod has a threaded connector formed along its axis. The threaded connector on one extension rod is connected to the internal threaded hole on another extension rod. A connecting block is provided at the top of the sampling cylinder. A threaded hole that mates with the threaded connector is vertically provided at the center of the connecting block. A threaded connector is provided at the lower end of the rotating handle, and the threaded connector is connected to the internal threaded hole at the end of the rod body.

[0015] When in use, two adjacent extension rods are connected end to end, and the rod is lengthened by the engagement of the threaded joint and the internal threaded hole. The rod is then engaged with the rotating handle and the connecting block through the internal threaded hole and the threaded joint.

[0016] Furthermore, each of the extension rods is marked with a scale, the horizontal fixing frame is convex in shape, the bottom of the horizontal fixing frame is provided with a horizontal reading bar, and the horizontal reading bar has an elongated hole at the position corresponding to the scale to expose the current scale value.

[0017] The scale on the extension rod allows users to accurately grasp the drilling depth, and the elongated hole on the horizontal reading bar allows them to quickly see the current depth into the ground.

[0018] Furthermore, the leveling mechanism is located at the four corners on both sides of the horizontal fixing frame. The leveling mechanism includes a long bolt rod, a locking bolt, and a limiting plate. Two bolt holes are respectively opened on both sides of the horizontal fixing frame. The long bolt rod passes downward through the bolt holes and the lower end of the long bolt rod is tapered. The locking bolt is threaded onto the long bolt rod and is located below the horizontal fixing frame. The limiting plate has a threaded hole and is threaded onto the long bolt rod. A limiting bolt is provided directly above the limiting plate. The limiting bolt is threaded onto the long bolt rod and its lower surface abuts against the upper surface of the limiting plate.

[0019] The locking bolts and long bolt rods are used to fix the horizontal fixing frame in the bolt holes at the four corners. The long bolt rods are then inserted into the ground. When the horizontal fixing frame is found to be uneven, the position of the limiting plate on the long bolt rod is adjusted by rotating the limiting plate. The limiting plate is in direct contact with the ground, thus leveling the horizontal fixing frame. The limiting bolts also limit the position of the limiting plate.

[0020] Furthermore, a level is provided on the upper surface of the horizontal fixing frame.

[0021] The level is mainly used in conjunction with the leveling mechanism to assist in ensuring that the leveling bracket is in a horizontal position.

[0022] Furthermore, the sealing baffle has a disc-shaped structure, the sealing baffle is integrally formed with the sliding rod, the thickness of the sealing baffle is greater than the width of the sampling port, and the outer wall of the sealing baffle is tightly fitted with the inner wall of the sampling cylinder.

[0023] The sealing baffle disc structure allows for better integration with the sampling port, and multiple sampling ports can be set at the same height for better sampling.

[0024] Beneficial effects: In use, the horizontal fixing frame is first placed on the ground and adjusted to a horizontal state by the leveling mechanism. Then, the sampling head is connected to the rod, and the rod is connected to the rotating handle. By rotating the rotating handle, the sampling head is driven to rotate downward. At this time, when the sampling head drills downward, the soil cone is resisted by the soil and thus fits tightly with the sampling cylinder. The sealing baffle blocks the sampling port to prevent shallow soil from entering the sampling port. When the expected depth is reached, the sampling head is pulled upward. The soil cone is separated from the sampling cylinder by gravity. The sliding rod drives the sealing baffle to move downward, opening the sampling port. Soil enters the sampling cylinder from the sampling port and is sampled in layers. When a deeper drilling depth is required, the rod can be extended to ensure the drilling depth, thereby enabling the understanding of the pollution of deep soil by organic pollutants, radioactive sources, and heavy metals.

[0030] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0031] Example:

[0032] As shown in Figures 1-4, this embodiment provides a method for collecting soil samples using a geological exploration sampling device, including a horizontal fixing frame 1, leveling mechanisms 2 at both ends of the horizontal fixing frame 1, and a sampling component 3 on the horizontal fixing frame 1;

[0033] The sampling component 3 includes a mounting base 301 horizontally mounted on the top surface of the horizontal fixing frame 1. A vertical rotating handle 302 is rotatably mounted inside the mounting base 301. A rod 303 is connected to the lower end of the rotating handle 302, and a sampling head 304 is provided at the lower end of the rod 303. The mounting base 301 mainly serves to limit the rotating handle 302, so as to keep it in a vertical state. At the same time, it works with the horizontal fixing frame 1 to keep the drilling in a straight line and prevent the drilling from deviating.

[0034] The sampling head 304 includes a drilling cone 3041 and a sampling cylinder 3042. The drilling cone 3041 is located below the sampling cylinder 3042, and a sliding rod 3043 is formed and connected to the upper end of the drilling cone 3041 along the axis. The sliding rod 3043 extends upward into the sampling cylinder 3042 and slides to connect with the bottom of the sampling cylinder 3042. Several sampling ports 3044 are evenly spaced on the side wall of the sampling cylinder 3042. A sealing baffle 3045 is provided on the part of the sliding rod 3043 inside the sampling cylinder 3042 corresponding to each sampling port 3044. When the top surface of the drilling cone 3041 is tightly attached to the bottom surface of the sampling cylinder 3042, the sliding rod 3043 abuts against the top of the sampling cylinder 3042, and the sealing baffle 3045 blocks the sampling port 3044. The sliding rod 3043 has a prismatic structure.

[0035] The working process and principle of the above structure are as follows:

[0036] In use, first place the horizontal fixing frame 1 on the ground, and adjust the horizontal fixing frame 1 to a horizontal state using the leveling mechanism 2. Then, connect the sampling head 304 to the rod body 303, and connect the rod body 303 to the rotating handle 302. By rotating the rotating handle 302, the sampling head 304 rotates downward. At this time, when the sampling head 304 drills downward, due to the resistance of the soil on the drilling cone 3041, it fits tightly with the sampling cylinder 3042. The sealing baffle 3045 blocks the sampling port 3044, preventing shallow soil from entering. Soil enters the sampling port 3044. After drilling to the expected depth, the sampling head 304 is pulled out upwards. The drilling cone 3041 separates from the sampling tube 3042 under gravity. The sliding rod 3043 drives the sealing baffle 3045 to move downwards, opening the sampling port 3044. Soil enters the sampling tube 3042 from the sampling port 3044 and is sampled in layers. When a deeper drilling depth is required, the rod 303 can be extended to ensure the drilling depth, thereby enabling an understanding of the pollution of deep soil by organic pollutants, radioactive sources, and heavy metals.

[0037] In another embodiment of the present invention, as shown in Figures 1 and 2, a plurality of conical retaining skirts 3046 are respectively provided on the outer side of the sampling cylinder 3042 corresponding to the position below each sampling port 3044. The opening angle of the retaining skirts 3046 is upward, and the taper of the retaining skirts 3046 is smaller the closer to the drilling cone 3041.

[0038] The purpose of the retaining skirt 3046 is to facilitate better scraping of soil when the sampling tube 3042 is being extracted for sampling, so that the soil can enter the sampling port 3044 for easy soil sampling. The tapered angle of the retaining skirt 3046 gradually decreases, which facilitates the downward drilling and movement of the sampling tube 3042.

[0039] In another embodiment of the present invention, as shown in FIG2, a sampling baffle 3047 is provided below each sampling port 3044 in the sampling cylinder 3042. The sampling baffle 3047 is coaxially arranged with the sampling cylinder 3042 and is horizontally and detachably fixed inside the sampling cylinder 3042.

[0040] The sampling baffle 3047 can both limit the sealing baffle 3045 and form a containment space to contain the sampled soil.

[0041] In another embodiment of the present invention, as shown in Figures 1-4, the rod body 303 includes a plurality of detachable extension rods 3031 connected in sequence. One end of the extension rod 3031 has an internal threaded hole 3032 along the axis, and the other end of the extension rod 3031 has a threaded connector 3033 formed along the axis. The threaded connector 3033 on one extension rod 3031 is connected to the internal threaded hole 3032 on another extension rod 3031. A connecting block is provided at the top of the sampling cylinder 3042. A threaded hole that mates with the threaded connector 3033 is vertically provided at the center of the connecting block 3048. A threaded connector 3033 is provided at the lower end of the rotating handle 302. The threaded connector 3033 is connected to the internal threaded hole 3032 at the end of the rod body 303. A sealing cap is connected to the lower part of the connecting block 3048. The sealing cap is detachably connected to the top of the sampling cylinder 3042, thereby facilitating better soil extraction.

[0042] When in use, two adjacent extension rods 3031 are connected end to end. The rod body 303 is lengthened by the engagement of the threaded joint 3033 and the internal threaded hole 3032. The rod body 303 is then engaged with the rotating handle 302 and the connecting block through the internal threaded hole 3032 and the threaded joint 3033.

[0043] In another embodiment of the present invention, as shown in Figures 1 and 3, each extension rod 3031 is marked with a scale 3034. The horizontal fixing frame 1 is convex in shape, and a horizontal reading bar 101 is provided at the bottom of the horizontal fixing frame 1. The horizontal reading bar 101 has an elongated hole 102 at the position corresponding to the scale 3034, exposing the current scale value on the scale 3034. The current insertion depth can be calculated based on the number of extension rods 3031 inserted, their own scale values, and the length of the sampling head 304.

[0044] The scale 3034 on the extension rod 3031 allows the user to accurately grasp the drilling depth, and the elongated hole 102 on the horizontal reading bar 101 allows the user to quickly see the current depth of the drilled part into the ground.

[0045] In another embodiment of the present invention, as shown in FIG1, the leveling mechanism 2 is disposed at the four corners on both sides of the horizontal fixing frame 1. The leveling mechanism 2 includes a long bolt rod 201, a locking bolt 202 and a limiting plate 203. Two bolt holes are respectively opened on both sides of the horizontal fixing frame 1. The long bolt rod 201 passes downward through the bolt holes and the lower end of the long bolt rod 201 is tapered. The locking bolt 202 is threaded on the long bolt rod 201 and is located below the horizontal fixing frame 1. The limiting plate 203 has a threaded hole and is threaded on the long bolt rod 201. A limiting bolt 204 is provided directly above the limiting plate 203. The limiting bolt 204 is threaded on the long bolt rod 201 and its lower surface abuts against the upper surface of the limiting plate 203.

[0046] By cooperating with the locking bolt 202 and the long bolt rod 201, it is fixed in the bolt holes at the four corners of the horizontal fixing frame 1, and the long bolt rod 201 is inserted into the ground. When the horizontal fixing frame 1 is found to be uneven, the position of the limiting plate 203 on the long bolt rod 201 is adjusted by rotating the limiting plate 203. The limiting plate 203 is in direct contact with the ground, thereby achieving the leveling of the horizontal fixing frame 1, and the limiting bolt 204 plays a limiting role for the limiting plate 203.

[0047] In another embodiment of the present invention, as shown in FIG1, a level 103 is provided on the upper surface of the horizontal fixing frame 1.

[0048] The level 103 is mainly used in conjunction with the leveling mechanism 2 to assist in ensuring that the leveling bracket 1 is in a horizontal state.

[0049] In another embodiment of the present invention, as shown in FIG2, the sealing baffle 3045 has a disc-shaped structure, the sealing baffle 3045 and the sliding rod 3043 are integrally formed, the thickness of the sealing baffle 3045 is greater than the width of the sampling port 3044, and the outer side wall of the sealing baffle 3045 is tightly fitted with the inner side wall of the sampling cylinder 3042.

[0050] The circular structure of the sealing baffle 3045 allows for better coordination with the sampling port 3044, and multiple sampling ports 3044 can be set at the same height for better sampling.
