Description

Technical Field

[0001] This invention relates to the field of mineral exploration equipment technology, and more particularly to a mineral exploration sampling device and method. Background Technology

[0002] Geological and mineral exploration is based on advanced geological science theories. It involves extensive field geological observation and the collection and organization of relevant geological data. It employs comprehensive geological means and methods, such as geological surveying, geophysical and geochemical exploration, and drilling engineering, to obtain reliable geological and mineral information. Geological and mineral exploration can be carried out by observing and testing the soil structure of geological layers using industrial microscopes. In the work of geological exploration, it is necessary to use sampling devices to take soil samples in advance, and then use testing instruments to test the soil samples.

[0003] When analyzing soil at different depths, many existing sampling devices often require multiple drilling operations, which is time-consuming and labor-intensive. They cannot separate and classify soil samples according to depth after a single drilling operation. Therefore, this application provides a mineral exploration sampling device and method. Summary of the Invention

[0004] The purpose of this invention is to provide a mineral exploration sampling device and method that is simple to operate and improves sampling efficiency.

[0005] This invention is achieved through the following measures: A mineral exploration sampling device, characterized in that it includes a base frame, a soil sampling mechanism and a soil sample separation mechanism disposed on the base frame; The base frame includes a base plate and several support parts disposed on the lower side of the base plate, and a through circular hole is provided in the middle of the base plate. The soil sampling mechanism includes a frame mechanism installed on the base plate, and a soil drilling mechanism is installed on the frame mechanism to obtain a soil sample column of a certain length. The soil sample separation mechanism includes a soil sample transfer mechanism disposed on the base plate and a soil sample box movably disposed on one side of the base plate. The soil sample transfer mechanism includes a cylindrical mechanism and a dividing mechanism that cooperates with the cylindrical mechanism. The soil sample box includes several sub-boxes. The soil sample column obtained by the drilling mechanism is transferred into the cylindrical mechanism, and then the dividing mechanism divides the soil sample column into several parts, each part corresponding to a soil sample at a specific depth, and then places them into the corresponding sub-boxes for storage.

[0006] The invention also has the following specific features: The frame mechanism includes a pair of uprights on the base plate. Each of the two uprights has a sliding groove on its inner side. A matching sliding plate is slidably arranged between the two sliding grooves. A through circular hole is provided in the middle of the sliding plate. The circular hole has the same diameter and is coaxial with the circular hole. The soil drilling mechanism is arranged through the circular hole and the circular hole. A motor is installed at the top of one of the uprights. A threaded hole is provided on the corresponding slide plate. A lead screw that mates with the threaded hole is installed in the corresponding slide groove. The lower end of the lead screw passes through the threaded hole and is rotatably mounted on the bottom surface of the slide groove. The upper end of the lead screw passes through the top surface of the slide groove and is mounted on the output end of the motor. The motor drives the lead screw to rotate, which in turn drives the slide plate to slide up and down, and in turn drives the soil drilling mechanism to move up and down.

[0007] The drilling mechanism includes an outer cylinder mechanism and an inner cylinder mechanism; The outer cylinder mechanism includes a thin-walled circular tube, which mates with both the second and first circular holes. The thin-walled circular tube rotates within the second and first circular holes, and can also slide up and down along the first circular hole. A gear is mounted on the outer side of the upper end of the thin-walled circular tube after passing through the second circular hole. The lower side of the gear is attached to the upper side of the slide plate. A motor is mounted on one side of the slide plate via a bracket plate. The output end of the motor is equipped with a gear that meshes with the first gear. An annular limiting plate mates with the second circular hole on the periphery of the thin-walled circular tube on the lower side of the slide plate. Several conical drill bits are mounted on the lower end face of the thin-walled circular tube. The motor drives the thin-walled circular tube to rotate, drilling soil through the several conical drill bits at the lower end. The inner cylinder mechanism is slidably mounted inside the thin-walled circular tube. The inner cylinder mechanism includes a disk, a semi-circular tube that mates with the inner side of the thin-walled circular tube on the lower side of the disk, and an annular groove coaxial with the semi-circular tube on the lower side of the disk. The annular groove extends from one side of the cross-section of the semi-circular tube to the other side and approaches the lower end of the semi-circular tube.

When the handle is at the other end in the arc-shaped groove, the semi-circular tube and the semi-circular tube form a closed tubular structure. The inner side of the thin-walled circular tube is provided with an arc-shaped block that mates with the second semi-circular tube. When the second semi-circular tube and the first semi-circular tube just form a closed tubular structure, the outer surfaces of the second semi-circular tube and the first semi-circular tube are both in contact with the inner surface of the thin-walled circular tube. An annular block is provided at the lower inner end of the thin-walled circular tube. The annular block cooperates with the tubular structure. When the first disc is attached to the upper side of the first gear, the lower side of the tubular structure is attached to the annular block, ensuring close cooperation between the outer cylinder mechanism and the inner cylinder mechanism. The upper side of the first disc is provided with a through threaded rod 2, and the upper side of the first gear is provided with a matching threaded insertion hole. The lower end of the threaded rod 2 passes through the first disc and is placed in the threaded insertion hole. The upper end of the threaded rod 2 is provided with a handle 2.

Correspondingly, a sliding groove is provided on the inner wall of the thin-walled circular tube, which mates with the inflation tube. The upper end of the sliding groove extends through the upper end face of the thin-walled circular tube. By inflating the annular airbag, the annular airbag expands and squeezes the soil sample column inside the inner cylinder mechanism, preventing the soil sample column inside the inner cylinder mechanism from falling off after the inner cylinder mechanism is lifted.

An arc-shaped groove, penetrating the second disc, is provided on the bottom surface of the annular groove opposite to the third semicircular tube. A groove is provided on one side of the upper surface of the fourth semicircular tube... The threaded rod three is fitted with the arc-shaped groove two. After the threaded rod three passes downward through the arc-shaped groove two, a sleeve two is provided on its outer periphery. The sleeve two is provided with a handle three. The semi-circular tube four can slide along the annular groove three through the handle three. When it slides to an appropriate position, the handle three is rotated to fix the semi-circular tube four. The length of the arc-shaped groove two is such that when the handle three is at one end in the arc-shaped groove two, the semi-circular tube four just slides completely into the inner side of the semi-circular tube three. When the handle three is at the other end in the arc-shaped groove two, the semi-circular tube four and the semi-circular tube three just form a closed tubular structure. After the second semicircular tube slides into the first semicircular tube, the third semicircular tube connects with the first semicircular tube. Then, the fourth semicircular tube slides into the third semicircular tube, so that the soil sample column in the inner cylinder mechanism can be transferred into the cylindrical mechanism. The inner sides of the semicircular tube four are provided with oblique cut surfaces, which can be more easily slidably inserted into the gap between the soil sample column and the semicircular tube one.

[0010] The dividing mechanism includes a pair of parallel plates, which are respectively disposed on the outer surfaces of the semicircular tube three near the two side sections. The free end of the rotating shaft two is disposed on one of the plates, and a cutting part is slidably disposed between the two plates.

A plurality of through grooves that cooperate with the blades are disposed on the side of the corresponding semi-circular tube three. The free end of the blade is configured as an arc-shaped structure that cooperates with the inner wall of the semi-circular tube four. The free end of the blade slides through the corresponding through groove and abuts against the inner wall of the semi-circular tube four. Sliding grooves three are disposed on the upper and lower sides of the opposite inner sides of the two flat plates. Sliding blocks that cooperate with the sliding grooves three are disposed on both sides of the blades at the top and bottom ends of the support rod. The sliding blocks are disposed in the corresponding sliding grooves three. A plurality of springs are provided between the support rod and the semicircular tube three. One end of each spring is provided on the support rod, and the other end of each spring is provided on the outer surface of the semicircular tube three. A clamping mechanism is provided on the lower side of the second disc. The clamping mechanism includes a through hole 1 located at the center of the second disc. A U-shaped bracket is provided on the lower side of the second disc. A through hole 2 matching the through hole 1 is provided on the bottom surface of the U-shaped bracket. An insert rod is slidably disposed through the through hole 1 and the through hole 2. A limiting hole cooperating with the insert rod is provided on the lower side of the blade plate at the bottom end. The upper end of the insert rod passes through the through hole 1 and is disposed in the limiting hole. A limiting ring plate is provided on the periphery of the insert rod near the lower side of the second disc. The limiting ring plate and the U-shaped bracket are connected. A second spring is provided around the insertion rod between the U-shaped brackets. One end of the second spring is located on the U-shaped bracket, and the other end is located on the limiting ring plate. A handle four is provided at the lower end of the insertion rod that passes through the through hole two. The upper end of the insertion rod is designed with an arc shape to facilitate entry into the limiting hole. The support rod is pushed until the insertion rod is inserted into the limiting hole under the action of the second spring. Then, the handle four is pulled down to disengage the insertion rod from the limiting hole. After that, the blade plate is reset and moves away from the inner side of the semi-circular tube three under the action of the first spring.

[0011] The soil sample separation mechanism also includes a lifting mechanism and a clamping mechanism; The lifting mechanism includes an electric telescopic rod two mounted on the base plate, an electric telescopic rod three mounted on the free end of the electric telescopic rod two, a downward-facing rotating shaft three mounted on the free end of the electric telescopic rod three, and a magnet mounted on the free end of the rotating shaft three.

The inner cylinder mechanism can be lifted by the electric telescopic rod two, the electric telescopic rod three, and the magnet, so as to cooperate with the soil sample separation mechanism.

[0012] The clamping mechanism includes a bidirectional lead screw mounted on the base plate via a second bracket plate. A guide rail rod parallel to the bidirectional lead screw is mounted on the base plate on one side of the bidirectional lead screw via a third bracket plate. Lead screw sliders are mounted on both sides of the bidirectional lead screw. The side of the lead screw slider away from the bidirectional lead screw is slidably mounted on the outer periphery of the guide rail rod. A clamping plate is mounted on the lead screw slider. The clamping plate includes a fixing block. Arc-shaped slots are provided on the inner sides of the two fixing blocks on opposite sides. One arc-shaped slot mates with the outer side of the semi-circular tube, and the outer side of the support rod mates with the arc-shaped slot on the other side. Arc-shaped magnetic plates are provided on the inner sides of the arc-shaped slots on both sides. Metal blocks mate with the arc-shaped magnetic plates are provided on the outer side of the semi-circular tube and the corresponding side of the support rod. A motor is installed on the base plate. One end of the bidirectional lead screw is located on the output end of the motor. The threads on both sides of the bidirectional lead screw rotate in opposite directions. The motor drives the bidirectional lead screw to rotate, which in turn drives the clamping plates on both sides to move towards the middle. Then, the arc-shaped slots on both sides clamp the inner cylinder mechanism and the soil sample transfer mechanism together.

[0013] The support includes four bracket plates at the four corners of the base plate. Each bracket plate has an electric telescopic rod extending to the ground. The free end of the electric telescopic rod is equipped with a caster wheel. When working, the electric telescopic rod is retracted so that the lower side of the base plate rests on the ground. When not working, the electric telescopic rod is extended so that the base plate moves away from the ground for easy movement. A handle is provided on the side of the base plate away from the soil sample box for pushing the entire device.

[0014] The specific steps are as follows: S1. Move the device to the sampling location, then retract the electric telescopic rod four so that the lower side of the base plate rests on the ground. Then start the motor two, and drive the soil drilling mechanism to rotate through the meshing of the gear two and the gear one. In the initial state, the inner cylinder mechanism is fixed to the outer cylinder mechanism through the handle two, and at the same time, the semi-circular tube two forms a closed tubular structure with the semi-circular tube one through the handle one. S2. Start the motor one, and drive the drilling mechanism to move downward through the circular hole one to perform drilling operations by rotating the lead screw. As the operation proceeds, the inner cylinder mechanism will be filled with soil sample columns. S3. After the drilling operation is completed, first inflate the annular airbag so that the annular airbag expands to clamp or cut off the bottom of the soil sample column. Then, start the lifting mechanism to lift the inner cylinder mechanism out of the outer cylinder mechanism and place it at the height that cooperates with the soil sample transfer mechanism. Then, by rotating the rotating shaft three, adjust the outer side of the semi-circular tube one to face the arc-shaped slot on the corresponding side. At this time, due to the action of the annular airbag, the soil sample column in the inner cylinder mechanism will not fall off. S4. Start the motor three, which drives the bidirectional lead screw to rotate, thereby moving the clamping plates on both sides towards the middle. Then, the arc-shaped magnetic plate and the metal block two on the corresponding side attract each other and continue to move until the two sides of the semicircular tube three are against the outer side of the semicircular tube two. Then, through the handle one, the semicircular tube two is rotated into the semicircular tube one. Then, the clamping plates on both sides continue to move until the two sides of the semicircular tube three are against the two sides of the semicircular tube one. At this time, the semicircular tube three and the semicircular tube one form a complete circular tube structure. S5. Using the handle three, the semicircular tube four is slid into the inside of the semicircular tube one and fixed. At this time, the semicircular tube four and the semicircular tube three form a closed tubular structure. At this time, the soil sample column is transferred into the tubular structure formed by the semicircular tube four and the semicircular tube three. S6. Continue to move the clamping plate towards the center. At this time, the clamping plate corresponding to the support rod will push several blades on the cutting part to penetrate into the tubular structure formed by the semi-circular tube four and the semi-circular tube three and abut against the inner wall of the semi-circular tube four. At this time, the cutting part will be locked by the clamping mechanism, and the soil sample column will be divided into several segments by several blades. S7. Then, remove the clamps on both sides and move the cylindrical mechanism and the dividing mechanism together against the soil sample box through the electric telescopic rod one and the rotating shaft two. At this time, the outer side of the semi-circular tube four faces the soil sample box. By setting the position of the soil sample box, the space formed by several dividing boxes and the corresponding adjacent blades on both sides can be made to correspond, that is, each segment of soil sample column after being divided is above the corresponding dividing box. S8. Release the clamping mechanism to reset the blade by disengaging it from the inner side of the tubular structure formed by the semicircular tube four and the semicircular tube three. Then slide the semicircular tube four back into the semicircular tube three. At this time, several soil sample columns will fall into the lower compartments. Thus, the soil samples in different compartments correspond to different depths. Based on the drilling depth, it is easy to distinguish the depths of the soil samples in different compartments.

[0015] The beneficial effects of this invention are: the device has a simple structure, the method is simple to operate, and it is convenient to use. After one drilling, the soil sample can be separated and classified according to the layer depth, which improves the sampling efficiency and exploration efficiency. Attached Figure Description

The length of the arc groove 2 37 is such that when the handle 3 40 is in one end of the arc groove 2 37, the semi-circular tube 47 just slides completely into the inner side of the semi-circular tube 3 32. When the handle 3 40 is in the other end of the arc groove 2 37, the semi-circular tube 47 and the semi-circular tube 3 32 just form a closed tubular structure. After the second semicircular tube 24 slides into the first semicircular tube 25, the third semicircular tube 32 connects with the first semicircular tube 25. Then the fourth semicircular tube 47 moves into the third semicircular tube 32, so that the soil sample column in the inner cylinder mechanism 19 can be transferred into the cylindrical mechanism 9. The two sides of the inner side of the semicircular tube 47 are provided with beveled surfaces, which make it easier to slide and insert into the gap between the soil sample column and the semicircular tube 25.

A U-shaped bracket is provided on the lower side of the second disc 36. A through hole 2 matching the through hole 1 is provided on the bottom surface of the U-shaped bracket. An insert rod is slidably arranged through the through hole 1 and the through hole 2. A limiting hole 44 cooperating with the insert rod is provided on the lower side of the blade plate 42 at the bottom end. The upper end of the insert rod passes through the through hole 1 and is placed in the limiting hole 44. A limiting ring plate is provided on the outer periphery of the insert rod near the lower side of the second disc 36. The limiting ring plate and the U-shaped bracket are...

A handle 39 is provided at the lower end of the insertion rod through the second through hole. The upper end of the insertion rod is set with an arc structure to facilitate entry into the limiting hole 44. Push the support rod 41 until the insertion rod is inserted into the limiting hole 44 under the action of the spring 38. Then pull down the handle 39 to make the insertion rod disengage from the limiting hole 44. Then the blade plate 42 is reset and moves away from the inner side of the semi-circular tube 32 under the action of the spring 35.

[0036] The soil sample separation mechanism also includes a lifting mechanism and a clamping mechanism; The lifting mechanism includes an electric telescopic rod 17 mounted on the base plate 1, an electric telescopic rod 16 mounted on the free end of the electric telescopic rod 17, a downward-facing rotating shaft 15 mounted on the free end of the electric telescopic rod 16, and a magnet mounted on the free end of the rotating shaft 15. A groove 21 that mates with the magnet is provided on the upper side of the center of the corresponding disc 45, and a metal block 1 that mates with the magnet is provided in the groove 21. The inner cylinder mechanism 19 can be lifted by the electric telescopic rod 17, the electric telescopic rod 16, and the magnet, so as to be used in conjunction with the soil sample separation mechanism.

[0037] The clamping mechanism includes a bidirectional lead screw 3 mounted on a base plate 1 via a bracket plate 2. A guide rail rod parallel to the bidirectional lead screw 3 is mounted on the base plate 1 on one side of the bidirectional lead screw 3 via a bracket plate 3. Lead screw sliders are mounted on both sides of the bidirectional lead screw 3. The side of the lead screw slider away from the bidirectional lead screw 3 is slidably mounted on the outer periphery of the guide rail rod. A clamping plate 46 is mounted on the lead screw slider. The clamp 46 includes a fixing block. Both sides of the fixing block have an arc-shaped groove 2 on their inner sides. One side of the arc-shaped groove 2 cooperates with the outer side of the semi-circular tube 25. The outer side of the support rod 41 cooperates with the arc-shaped groove 2 on the other side. Both sides of the arc-shaped groove 2 have a cooperating arc-shaped magnetic plate on their inner sides. The outer side of the semi-circular tube 25 and the corresponding side of the support rod 41 are provided with a metal block 2 that cooperates with the arc-shaped magnetic plate. A motor 6 is installed on the base plate 1. One end of the bidirectional lead screw 3 is set on the output end of the motor 6. The threads on both sides of the bidirectional lead screw 3 rotate in opposite directions. The motor 6 drives the bidirectional lead screw 3 to rotate, which in turn drives the clamping plates 46 on both sides to move towards the middle. Then, the arc-shaped slots 2 on both sides clamp the inner cylinder mechanism 19 and the soil sample transfer mechanism.

[0038] The support includes four bracket plates at the four corners of the base plate 1. Each bracket plate has an electric telescopic rod extending to the ground. The free end of the electric telescopic rod is equipped with casters. When working, the electric telescopic rod is retracted so that the lower side of the base plate 1 rests on the ground. When not working, the electric telescopic rod is extended so that the base plate 1 is moved away from the ground for easy movement. A handle is provided on the side of the base plate 1 away from the soil sample box for pushing the entire device.

[0039] The specific steps are as follows: S1. Move the device to the sampling location, then retract the electric telescopic rod four so that the lower side of the base plate 1 rests on the ground. Then start the motor two 11, which drives the soil drilling mechanism 10 to rotate through the meshing of gear two 48 and gear one 27. In the initial state, the inner cylinder mechanism 19 is fixed to the outer cylinder mechanism through the handle two 20, and at the same time, the semi-circular tube two 24 forms a closed tubular structure with the semi-circular tube one 25 through the handle one 23. S2. Start motor 13, drive the drilling mechanism 10 through the rotation of lead screw 12 to move downward through the round hole to carry out drilling operation. As the operation proceeds, the inner cylinder mechanism 19 will be filled with soil sample column. S3. After the drilling operation is completed, first inflate the annular airbag 26 so that the annular airbag 26 expands to clamp or cut off the bottom of the soil sample column. Then, start the lifting mechanism to lift the inner cylinder mechanism 19 out of the outer cylinder mechanism and place it at the height that matches the soil sample transfer mechanism. Then, by rotating the rotating shaft 15, adjust the outer side of the semi-circular tube 25 to face the corresponding side arc-shaped slot 2. At this time, due to the action of the annular airbag 26, the soil sample column in the inner cylinder mechanism 19 will not fall off. S4. Start motor 36. Motor 36 drives the bidirectional lead screw 3 to rotate, which in turn drives the two side clamps 46 to move towards the middle. Then, the corresponding side arc magnetic plate and metal block 2 are attracted together. Continue to move until the two sides of the semicircular tube 32 are against the outer side of the semicircular tube 24. Then, through the handle 1 23, the semicircular tube 24 is rotated into the semicircular tube 1 25. Then continue to move the two side clamps 46 until the two sides of the semicircular tube 32 are against the two sides of the semicircular tube 1 25. At this time, the semicircular tube 32 and the semicircular tube 1 25 form a complete circular tube structure. S5. Using handle 3 40, the semicircular tube 47 is slid into the inside of the semicircular tube 1 25 and fixed. At this time, the semicircular tube 47 and the semicircular tube 32 form a closed tubular structure. The soil sample column is then transferred into the tubular structure formed by the semicircular tube 47 and the semicircular tube 32. S6. Continue to move the clamping plate 46 towards the center. At this time, the clamping plate 46 corresponding to the support rod 41 will push several blades 42 on the cutting part to penetrate into the closed tubular structure formed by the semi-circular tube 47 and the semi-circular tube 32 and abut against the inner wall of the semi-circular tube 47. At this time, the cutting part will be locked by the clamping mechanism, and the soil sample column will be divided into several segments by several blades 42. S7. Then remove the two side clamps 46, and move the cylindrical mechanism 9 and the dividing mechanism 8 together against the soil sample box through the electric telescopic rod 4 and the rotating shaft 5. At this time, the outer side of the semi-circular tube 47 faces the soil sample box. By setting the position of the soil sample box, the space formed by several sub-boxes 7 and the corresponding adjacent two side blades 42 can be made to correspond, that is, each segment of the soil sample column after being divided is above the corresponding sub-box 7. S8. Loosen the clamping mechanism to allow the blade 42 to disengage from the inner side of the tubular structure formed by the semicircular tube 47 and the semicircular tube 32 and reset. Then slide the semicircular tube 47 back into the semicircular tube 32. At this time, several sections of soil sample columns will fall into the lower compartment 7. Thus, the soil samples in different compartments 7 correspond to different layer depths. Based on the drilling depth, it is easy to distinguish the depths corresponding to the soil samples in different compartments 7.
