Description

Technical Field

[0001] The invention belongs to the technical field of geological exploration auxiliary equipment, in particular to a groove sampling device for geological and mineral exploration. Background Art

[0002] Mineral exploration is a practical geology that studies the geological conditions of mineral formation and distribution, the laws of mineral deposit occurrence, the characteristics of ore body changes, and the most effective methods for identifying and evaluating industrial mineral deposits. Geological and mineral exploration often requires geological mapping. When sampling ore in mine geology, samples of certain specifications need to be collected for analysis, testing or identification. At present, the more commonly used method is the groove method, that is, cutting a long groove along the thickness direction of the ore body surface, and then using a metal rod component to pry open the gravel. The purpose of this method is to obtain ore samples at different levels of the profile, but this method has obvious defects. The middle of the cut long groove is generally a relatively complete sample plate, but the efficiency of using a metal rod to pry is low. Due to the deep long groove, the metal rod prying will cause the fracture of the ore sample to be high, making it impossible to remove the ore at the bottom of the cut. The inability to completely remove the ore will lead to deviations in subsequent analysis and detection, which will bring an imprecise impact on geological exploration work. Therefore, there is an urgent need for a sampling device that can realize a complete sampling function. Summary of the invention

[0005] As a preferred solution of the present invention, the outer surface of the support column one is movably sleeved with two groups of springs one respectively located on the left and right sides of the slider one, the two ends of the spring one are elastically connected to the top plate and the slider one respectively, the slider one is located in the middle of the outer surface of the support column one, and can slide freely along the surface of the support column one.

[0006] As a preferred solution of the present invention, the cross-sectional shape of the slider 2 is a right-angled trapezoid, the inclined surface of the slider 2 faces upward and is in sliding contact with the pressure surface.

[0007] As a preferred solution of the present invention, the left and right groups of splints are respectively engaged in cutting groove two and cutting groove one, the thickness value of the left splint is smaller than the width value of cutting groove two, and the thickness value of the right splint is smaller than the width value of cutting groove one.

[0008] As a preferred solution of the present invention, a paving inclined surface is provided at the bottom of the clamping plate, and the paving inclined surface faces one side of the sample.

[0009] As a preferred solution of the present invention, guide columns are fixedly connected to both the front and rear sides of the top of the pressure plate, and the top of the guide column penetrates upward to the top of the support plate.

[0010] As a preferred solution of the present invention, the cross-sectional shapes of the support plate and the pressure plate are both "U"-shaped, and the support plate is elastically mounted on the top of the pressure plate through spring 2.

[0011] As a preferred solution of the present invention, the buffer pad is made of a rubber block, the thickness of the buffer pad is greater than the length of the clamping column, and the clamping columns are arranged in multiple groups and respectively distributed at the bottom and front and rear sides of the side of the splint.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device has been redesigned to achieve the complete sampling function of the sample. Two groups of symmetrically distributed clamping plates are arranged to correspond to the cutting groove 2 and the cutting groove 1 respectively. Driven by the hydraulic cylinder, the two groups of clamping plates are respectively inserted into the cutting groove 2 and the cutting groove 1. The relative sliding between the connecting column, the pressing plate, the supporting plate and the sliding block 2 is utilized to make the clamping plates move to the bottom of the cutting groove 1 and the cutting groove 2. The pressing plates are used to press the two groups of sliding blocks 2 located on the surface of the supporting column 2, so that they move toward each other synchronously, and the two groups of clamping plates and the buffer pad are respectively driven to press toward the surface of the sample, so that the clamping plates and the sample form a seamless structure. The two groups of clamping plates move toward each other and are squeezed and deformed, so that the clamping column can abut against the surface of the sample, and its small area and high pressure characteristics can press cracks on the edge of the sample surface, so that the sample and the ore body have a tendency to separate. Combined with the flexible wrapping of the buffer pad, the sample itself can be effectively protected, laying the foundation for subsequent complete sampling.

[0014] 2. The device is provided with a hydraulic cylinder which is rotatably mounted on the outer surface of the fixed column and slidably mounted on the outer surface of the support column one through a slider one. The support column one applies pressure to the slider one from both sides to ensure that the hydraulic cylinder can operate in a vertical state in the early stage of sampling. When the clamp moves to the side of the sample, the slider two is pressed by the spring three, driving the clamp, the buffer pad and the sample to apply pressure and generate friction. As the clamp moves downward, the friction increases. Finally, when the clamp clamps the sample, it moves to the bottom of the cutting groove one and the cutting groove two. Due to the friction, the bottom of the clamp will not touch the cutting groove. 1. There is no gap at the bottom of the cutting groove 2. When the pressure plate can no longer press the slider 2, the connecting column no longer moves downward. At this time, the thrust generated by the hydraulic cylinder continuing to extend outward drives the hydraulic cylinder at one end of the fixed column to rotate in the opposite direction. At the same time, it drives the fixed column and the slider 1 to move along the surface of the support column 1 toward the side of the support column 1. At this time, the hydraulic cylinder as a whole tilts and rotates, and drives the splint and the sample as a whole to deflect through the connecting column. At this time, the sample is driven to completely break the cracks generated at the joint with the clamping column, thereby effectively ensuring that the sample is preserved intact.

[0015] 3. Finally, the present invention also provides springs three on both sides of the outer surface of the second supporting column, which are compressed by the slider two to generate rebound pressure. The rebound pressure is pressed by the slider two to make it as close to the sample surface as possible in the early stage of sampling, so as to ensure that the buffer pad fits the sample. After the sample is broken by the clamping column and the clamping plate is rotated as a whole to remove the sample, the pressure of the spring three on the slider two makes the pressure plate no longer press on the slider two, and the slider two can also drive the clamping plate to press on the sample, thereby ensuring that the sample that is pressed and broken can be smoothly taken out from the cutting groove one and the cutting groove two under the friction force generated by the clamping plate and the buffer pad.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 8As shown, an embodiment of the present invention provides a groove sampling device for geological and mineral exploration, including two groups of brackets 1, a top plate 2 is fixedly installed on the top of the bracket 1, two groups of support columns 3 that are parallel to each other are fixedly installed on the inner wall of the top plate 2, a slider 4 is slidably installed on the outer surface of the support column 3, a fixed column 6 is fixedly installed in the middle of the two groups of sliders 4, a hydraulic cylinder 7 is rotatably installed on the outer surface of the fixed column 6, a connecting column 8 is rotatably installed on the telescopic end of the hydraulic cylinder 7, a supporting plate 12 and a spring 10 are movably sleeved on the outer surface of the connecting column 8, a pressing plate 9 is fixedly connected to the bottom of the connecting column 8, a pressure surface 15 is provided at the bottom of the pressing plate 9, and both ends of the spring 10 are respectively connected to the hydraulic cylinder 7 and the hydraulic cylinder 7. The pressure plate 9 is elastically connected to the support plate 12. A plurality of groups of support columns 13 arranged in parallel front and back are fixedly installed at the bottom of the inner wall of the support plate 12. Two groups of sliders 14 are slidably installed on the outer surface of the support column 13. The pressure surface 15 abuts against the slider 14. Both ends of the outer surface of the support column 13 are movably sleeved with springs 16. The two ends of the spring 16 are elastically connected to the slider 14 and the inner wall of the support plate 12 respectively. A clamping plate 17 is fixedly connected to the bottom of the slider 14. The opposite surfaces of the two groups of clamping plates 17 are glued with buffer pads 18. The surface of the buffer pad 18 is provided with a placement hole 19. The side of the clamping plate 17 is fixedly connected with a clamping column 20 located inside the placement hole 19.

[0027] like Figure 2 As shown, a cutting machine is used to open a cutting groove 1 23 and a cutting groove 24 parallel to each other on the surface of an ore body 22, and a sample 25 is formed in the middle. The sample 25 is what the metal rod is to pry open.

[0028] The device has been redesigned to achieve a complete sampling function for the sample 25. Two groups of symmetrically distributed clamping plates 17 are provided, which correspond to the cutting groove 24 and the cutting groove 1 23 respectively. Driven by the hydraulic cylinder 7, the two groups of clamping plates 17 are respectively inserted into the cutting groove 24 and the cutting groove 1 23. The clamping plates 17 are moved to the bottom of the cutting groove 1 23 and the cutting groove 24 by the relative sliding between the connecting column 8, the pressing plate 9, the supporting plate 12 and the sliding block 2 14. The pressing plate 9 is used to press the two groups of sliding blocks 2 14 located on the surface of the supporting column 2 13 to make them move. The two groups of clamps 17 and the buffer pads 18 move toward each other synchronously, and respectively drive the two groups of clamps 17 and the buffer pads 18 to press against the surface of the sample 25, so that the clamps 17 and the sample 25 form a seamless structure. The two groups of clamps 17 move toward each other and are squeezed and deformed, so that the clamping column 20 can abut against the surface of the sample 25, and the small area and high pressure characteristics of the clamping column 20 press cracks at the edge of the surface of the sample 25, so that there is a tendency for separation between the sample 25 and the ore body 22. Combined with the flexible wrapping of the buffer pad 18, the sample 25 itself can be effectively protected, laying a foundation for subsequent complete sampling.

[0029] Among them, the outer surface of the support column 3 is movably sleeved with two groups of springs 5 ​​respectively located on the left and right sides of the slider 4, and the two ends of the spring 5 are elastically connected to the top plate 2 and the slider 4 respectively. The slider 4 is located in the middle of the outer surface of the support column 3 and can slide freely along the surface of the support column 3;

[0030] The device is provided with a hydraulic cylinder 7 which is rotatably mounted on the outer surface of the fixed column 6 and slidably mounted on the outer surface of the support column 3 through a slider 4. The support column 3 applies pressure to the slider 4 from both sides to ensure that the hydraulic cylinder 7 can operate in a vertical state in the early stage of sampling. When the clamp 17 moves to the side of the sample 25, the slider 2 14 is pressed by the spring 3 16, driving the clamp 17, the buffer pad 18 and the sample 25 to apply pressure and generate friction. As the clamp 17 moves downward, the friction becomes greater. Finally, when the clamp 17 clamps the sample 25, it moves to the bottom of the cutting groove 1 23 and the cutting groove 2 24. Due to the generation of friction, the bottom of the clamp 17 will not touch the cutting groove 25. There is no gap at the bottom of the cutting groove 1 23 and the cutting groove 2 24. When the pressure plate 9 can no longer press the slider 2 14, the connecting column 8 no longer moves downward. At this time, the thrust generated by the hydraulic cylinder 7 continuing to extend outward drives the hydraulic cylinder 7 at one end of the fixed column 6 to rotate in the reverse direction. At the same time, it drives the fixed column 6 and the slider 4 to move along the surface of the support column 3 toward one side of the support column 3. At this time, the hydraulic cylinder 7 tilts and rotates as a whole, and drives the splint 17 and the sample 25 to deflect as a whole through the connecting column 8. At this time, the sample 25 is driven to completely break the cracks generated at the abutment between the sample 25 and the clamping column 20, thereby effectively ensuring that the sample 25 is preserved intact.

[0031] Finally, the present invention also provides spring three 16 on both sides of the outer surface of support column two 13, which is compressed by slider two 14 to generate rebound pressure. The rebound pressure is pressed by slider two 14 to make it as close to the surface of sample 25 as possible in the early stage of sampling, so as to ensure that the buffer pad 18 fits with the sample 25. After the sample 25 is pressed and broken by the clamping column 20 and the clamping plate 17 rotates as a whole to remove the sample 25, the pressure of the spring three 16 on the slider two 14 makes the pressure plate 9 no longer apply pressure to the slider two 14, and the slider two 14 can also drive the clamping plate 17 to apply pressure to the sample 25, thereby ensuring that the sample 25 that is pressed and broken and removed can be smoothly taken out from the cutting groove one 23 and the cutting groove two 24 under the friction force generated by the clamping plate 17 and the buffer pad 18.

[0032] The cross-section of the slider 14 is a right-angle trapezoid, the inclined surface of the slider 14 faces upwards and is in sliding contact with the pressure surface 15;

[0033] The bottom edges of the two sets of symmetrically distributed sliders 14 are kept in vertical and relative positions. This design allows the pressure surface 15 opened at the bottom of the pressure plate 9 to slide against the inclined surface of the slider 14, thereby converting the downward displacement of the pressure plate 9 into a horizontal displacement of the slider 14, which helps the slider 14 to drive the clamping plate 17 to move and clamp the sample 25.

[0034] The left and right clamps 17 are respectively engaged in the second cutting groove 24 and the first cutting groove 23, the thickness of the left clamp 17 is less than the width of the second cutting groove 24, and the thickness of the right clamp 17 is less than the width of the first cutting groove 23;

[0035] When the clamp 17 is inserted into the cutting groove 1 23 or the cutting groove 2 24 , since its thickness is smaller than the width of the cutting groove 1 23 or the cutting groove 2 24 , the clamp 17 can generate a rotational motion in the cutting groove 1 23 or the cutting groove 2 24 after clamping the sample 25 , and "break" the sample 25 , providing space for the sampling movement of the clamp 17 .

[0036] The bottom of the clamping plate 17 is provided with a paving inclined surface 21, and the paving inclined surface 21 faces one side of the sample 25;

[0037] The purpose of the opening of the evacuation slope 21 is to ensure that when the bottom of the clamping plate 17 contacts the sample 25 , it will not abut against the straight upper surface of the sample 25 to generate an opening phenomenon, so as to ensure that the two sets of clamping plates 17 are separated along the two sides of the sample 25 .

[0038] Among them, the front and rear sides of the top of the pressing plate 9 are fixedly connected with guide columns 11, and the top of the guide column 11 penetrates upward to the top of the support plate 12;

[0039] The guide column 11 is responsible for providing guidance for the movement of the pressure plate 9. When the connecting column 8 drives the pressure plate 9 to move downward, the whole is kept in a vertical state, so that the inclined surface of the slider 14 and the pressure surface 15 are kept in close contact.

[0040] The cross-sectional shapes of the support plate 12 and the pressure plate 9 are both "U" shaped, and the support plate 12 is elastically mounted on the top of the pressure plate 9 through a spring 2 10;

[0041] The pressure plate 9 and the support plate 12 are designed to be nested inside and outside. The support plate 12 is elastically made on the top of the pressure plate 9 by the spring 10. The "U" shape design of the support plate 12 allows multiple groups of support columns 13 to be installed at the bottom of its inner wall, and provides sliding support for the slider 14. The "U" shape design of the pressure plate 9 ensures that the two groups of pressure surfaces 15 opened at its bottom are in contact with the slider 14 and generate a horizontal thrust on the slider 14.

[0042] The buffer pad 18 is made of a rubber block, the thickness of the buffer pad 18 is greater than the length of the clamping column 20, and the clamping column 20 is arranged in multiple groups and respectively distributed at the bottom and the front and rear sides of the side of the clamping plate 17;

[0043] The function of the buffer pad 18 is, on the one hand, to abut against the surface of the sample 25 to produce a buffer protection function, and on the other hand, to generate friction with the surface of the sample 25 under the action of the spring three 16 pushing the slider two 14 and the clamping plate 17, and to make the two sets of clamping plates 17 and the surface of the sample 25 continuously clamped to force the clamping plates 17 to stop moving when they are close to the bottom of the cutting groove one 23 and the cutting groove two 24 by friction, so as to avoid that the gap between the clamping plates 17 and the bottom of the cutting groove one 23 and the cutting groove two 24 is too small, thereby preventing the subsequent rotation of the clamping plates 17.

[0044] Working principle:

[0045] First, a cutting machine is used to cut a cutting groove 24 and a cutting groove 1 23 parallel to each other on the surface of the ore body 22 in the thickness direction thereof, such as Figure 2 As shown, on the surface of the ore body 22, a sample 25 is formed between the cutting groove 1 23 and the cutting groove 2 24, at which time, the sampling operation can be performed;

[0046] Move the device to the top of the sample 25, so that the two groups of clamps 17 are vertically aligned with the cutting groove 1 23 and the cutting groove 2 24 respectively, then start the hydraulic cylinder 7 and drive the connecting column 8 downward to move downward. At this time, the support plate 12 drives the supporting column 2 13, the sliding block 2 14 and the clamp 17 to move downward under the action of gravity, and the clamp 17 begins to enter the cutting groove 1 23 and the cutting groove 2 24. At this time, the buffer pad 18 abuts against the sample 25 and is squeezed. When the bottom of the clamp 17 abuts against the bottom of the cutting groove 1 23 and the cutting groove 2 24, the clamp 17 and the sliding block 2 14 stop moving;

[0047] Then, the hydraulic cylinder 7 continues to drive the connecting column 8 and the pressure plate 9 to move downward. At this time, since the slider 14 no longer moves downward, the pressure surface 15 at the bottom of the pressure plate 9 slides and abuts against the inclined surface at the top of the slider 14 during the downward movement, and applies pressure, so that the two groups of sliders 14 make synchronous relative movements along the axial direction of the support column 13, that is, drive the left and right groups of clamping plates 17 to move towards each other and gradually approach each other. At this time, the buffer pad 18 is subjected to the extrusion force between the clamping plate 17 and the sample 25, and begins to continue to deform, and its thickness becomes smaller, and gradually becomes flush with the outer end of the clamping column 20. At this time, the outer end of the clamping column 20 abuts against the surface of the sample 25 and begins to apply pressure to the surface of the sample 25. As the pressure plate 9 continues to move downward, the slider 14 drives the clamping plate 17 and the clamping column 20 to apply pressure to the surface of the sample 25, so that cracks are generated at the position where the surface of the sample 25 abuts against the clamping column 20. At this time, the two groups of clamping plates 17 completely preserve the broken part of the sample 25 through the buffer pad 18 and the clamping column 20.

[0048] Finally, the downward relative movement of the pressure plate 9 relative to the support plate 12 stops, while the hydraulic cylinder 7 continues to extend outward, causing the hydraulic cylinder 7 to rotate and be installed on one end of the outer surface of the fixed column 6, and drive the fixed column 6 and the slider 4 to slide along one side of the outer surface of the support column 3. The spring 5 on one side of the outer surface of the support column 3 is compressed, and the spring 5 on the other side is stretched. At the same time, the telescopic end of the hydraulic cylinder 7 also drives the connecting column 8, the support plate 12, the slider 14 and the clamping plate 17 to rotate as a whole toward the other side of the rotation and inclination of the hydraulic cylinder 7. With the bottom of the clamping plate 17 as the fulcrum, the sample 25 is moved by two The group of clamping plates 17 clamps and generates a rigid torque through rotation to completely "break" the sample 25 off. Subsequently, the hydraulic cylinder 7 is contracted and drives the connecting column 8 and the support plate 12 to move upward and reset. The hydraulic cylinder 7 is reset to the original vertical position under the action of the support column 13 and the slider 14. The pressure plate 9 moves upward driven by the connecting column 8 and compresses the spring 2 10. The pressure of the pressure plate 9 is lost. Under the elastic force of the spring 3 16, the slider 2 14 drives the two groups of clamping plates 17 and the buffer pad 18 to clamp the "broken" sample 25, and then brings the sample 25 out to complete the sampling operation.
