Description

Technical Field

[0001] This invention relates to the field of geological sampling technology, specifically a sampler for mineral geological exploration. Background Technology

[0002] Geological exploration, broadly speaking, can be understood as geological work. It is the investigation and research work conducted on the geological conditions of rocks, stratigraphy, minerals, groundwater, landforms, etc. in a certain area, based on the needs of economic construction, national defense construction, and scientific and technological development, using geological exploration methods such as surveying, geophysical exploration, geochemical prospecting, drilling, pit exploration, sampling and testing, and geological remote sensing.

[0003] The previous sampling device mainly used a servo motor to drive the sampling cylinder and the annular soil drill to move down to the ground, so that the soil to be sampled could enter the sampling cylinder and thus complete the sampling. However, as the sampling depth increased, the friction between the sampling cylinder and the inner wall of the hole increased, which caused the rotation speed of the sampling cylinder to decrease, and eventually it could not continue to move down, resulting in the inability to sample. Summary of the Invention

[0004] The purpose of this invention is to provide a sampler for mineral geological exploration to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A sampler for mineral geological exploration includes a base plate, characterized in that a circular hole is formed on the upper surface of the base plate, a sampling tube is inserted into the circular hole, an annular drill bit is installed at one end of the sampling tube, a protective member is provided on the annular surface of the sampling tube, the protective member is in contact with the annular drill bit, a deflector is installed on the annular surface of the sampling tube, the deflector is rotatably connected inside the protective member, an air inlet pipe is installed at the upper end of the protective member, the end of the air inlet pipe away from the protective member is connected to an air compressor, a lifting member is installed on the upper surface of the base plate, a rotating member is installed on the upper surface of the lifting member, and an external threaded groove is formed on the surface of the sampling tube, the rotating member is threadedly connected to the external threaded groove.

[0006] Furthermore, the protective component includes two semi-circular outer cylinders, which are disposed outside the sampling cylinder. Two semi-circular plates are installed at the ends of the semi-circular outer cylinders, and the semi-circular plates are connected to both semi-circular outer cylinders. Annular grooves are formed on the inner annular surfaces of both semi-circular plates. The deflector is rotatably connected within the annular grooves. Multiple annularly spaced air inlet slots are formed inside the semi-circular outer cylinders, and these air inlet slots communicate with the space inside the semi-circular outer cylinders. Exhaust slots are formed on both the left and right sides of each air inlet slot. Both the air inlet slots and exhaust slots penetrate the semi-circular plates. Multiple slots are formed on the upper surface of the semi-circular plates, and mounting plates are installed within these slots. The air inlet pipe is mounted on the mounting plate and communicates with the air inlet slots.

[0007] Furthermore, the deflector includes two semicircular rings, which are mounted on the annular surface of the sampling cylinder. Multiple blocking blocks are mounted on the side of the semicircular rings away from the sampling cylinder. A conical hole is opened on the upper surface of the blocking block, and a one-way component is installed in the conical hole. A deflector plate is installed between two adjacent blocking blocks. The deflector plate and the blocking blocks are rotatably connected in the annular groove, and the deflector plate and the blocking blocks are in sliding contact with the exhaust groove and the intake groove.

[0008] Furthermore, the one-way component includes a conical block inserted into a conical hole, a support rod installed at the tip of the conical block, a blocking plate installed at the end of the support rod away from the conical block, a limiting groove opened on the side of the blocking block away from the conical hole, and the blocking plate inserted into the limiting groove.

[0009] Furthermore, a connecting ring is rotatably connected to the upper surface of the annular drill bit, and the side of the connecting ring away from the annular drill bit is connected to the semi-circular outer cylinder. The annular upper surface of the annular drill bit is provided with multiple vertical grooves, and the air inlet groove and the exhaust groove are both connected to the vertical grooves.

[0010] Furthermore, the inner surface of the annular drill bit is provided with a transverse groove extending to the upper surface of the annular drill bit. The transverse groove penetrates the vertical groove. An inclined block is slidably connected in the transverse groove. A circular groove is provided on the side of the inclined block facing the transverse groove. A pulling member is installed in the circular groove. One end of the inclined block of the pulling member is installed in the vertical groove. The inclined block faces the drill bit inside the annular drill bit.

[0011] Furthermore, the pulling member includes an elastic element, which is installed in a circular groove. A connecting rod is installed at the end of the elastic element facing out of the circular groove, and the end of the connecting rod away from the elastic element is installed in a vertical groove.

[0012] Furthermore, the lifting component includes multiple vertical cylinders, which are mounted on the upper surface of the base plate. A connecting pipe communicating with an air compressor is installed on the lower side of the annular surface of the vertical cylinder. Movable rods are slidably connected inside the vertical cylinders, and support plates are installed at the ends of the multiple movable rods away from the vertical cylinders. The rotating component is mounted on the upper surface of the support plate.

[0013] Furthermore, the rotating component includes a servo motor, which is mounted on the upper surface of the support plate. The output end of the servo motor passes through the support plate and is fitted with a threaded cylinder. Furthermore, the lower end of the sampling cylinder has an external threaded groove, which is threadedly connected to the internal threaded groove of the upper sampling cylinder.

[0014] The sampler for mineral geological exploration provided by this invention has the following beneficial effects: 1. This invention provides a protective structure consisting of a semi-circular outer cylinder and a semi-circular plate on the annular surface of the sampling cylinder. This protective structure isolates the outside of the sampling cylinder from sand and gravel on the inner wall of the hole, thereby reducing the rotational friction of the sampling cylinder. Furthermore, a deflection structure consisting of a semi-circular ring, a blocking block, and a deflection plate is installed on the annular surface of the sampling cylinder. The gas introduced into the air inlet groove on the semi-circular outer cylinder promotes the rotation of the deflection structure, thereby improving the rotational efficiency of the sampling cylinder.

[0015] 2. This invention utilizes a blocking block to seal the annular groove, preventing air from the inlet groove from directly entering the exhaust groove. A conical hole is then created on the deflection structure, and a one-way structure consisting of a conical block, a support rod, and a blocking plate is installed within the conical hole. This one-way structure facilitates the passage of air from the exhaust groove. When the one-way structure isolates the inlet groove, the air flowing within it compresses the one-way structure, creating a downward impact force. This facilitates the sampling tube driving the annular drill bit downwards. Furthermore, the air entering the inlet groove eventually passes through the vertical groove on the annular drill bit before exiting the exhaust groove, carrying away heat and excess sand and dust generated during the drilling process, preventing sand and dust accumulation from hindering the descent of the annular drill bit.

[0016] 3. This invention creates a transverse groove inside the annular drill bit and installs a wedge block, drill bit, elastic element, and elastic element inside the transverse groove. By sealing the exhaust groove, the air entering the intake groove can no longer be discharged through the exhaust groove and can only flow out to the outside through the transverse groove. This squeezes the wedge block and drives the drill bit to move into the annular drill bit, cutting off the sample collected in the sampling tube, so that the sampling tube can bring the collected sample back to the ground.

[0024] Please see Figures 1 to 8 The sampler for mineral geological exploration provided by the present invention includes a base plate 1. A circular hole is formed on the upper surface of the base plate 1, and a sampling cylinder 7 is inserted into the circular hole. A ring drill bit 11 is installed on the side of the sampling cylinder 7 away from the limiting member. Multiple vertical cylinders 2 are installed on the upper surface of the base plate 1. A connecting pipe 9 communicating with an air compressor is installed on the lower side of the annular surface of the vertical cylinder 2. Movable rods 3 are slidably connected inside the vertical cylinders 2. A support plate 4 is installed at the end of the multiple movable rods 3 away from the vertical cylinders 2. A servo motor 5 is installed on the upper surface of the support plate 4. The output end of the servo motor 5 passes through the support plate 4 and is fitted with a threaded cylinder 6. The threaded cylinder 6 is threadedly connected to the sampling cylinder 7. Air is introduced into the vertical cylinders 2 by the air compressor. The air is then used to raise the height of the servo motor 5 mounted on the movable rod 3. The sampling tube is then threadedly connected to the threaded cylinder 6. The servo motor 5 is then started to drive the sampling cylinder 7 to rotate. The rotation of the sampling cylinder 7 drives the annular drill bit 11 to rotate and break through the soil. Then, the air compressor is used to remove the air from the vertical cylinder 2 to lower the height of the support plate 4. At this time, the annular drill bit 11 can drive the sampling tube to rotate downward continuously. The lower end of the sampling cylinder 7 has an external threaded groove 30, which is threadedly connected to the internal threaded groove 31 of the upper sampling cylinder 7. The cooperation between the external threaded groove 30 and the internal threaded groove 31 allows multiple sampling cylinders 7 to be connected to each other.

[0025] In some embodiments, two semicircular rings 25 are installed on the annular surface of the sampling cylinder. A plurality of blocking blocks 23 are installed on the side of the semicircular rings 25 away from the sampling cylinder 7. A conical hole is opened on the upper surface of the blocking block 23, and a conical block 24 is inserted into the conical hole. A support rod 26 is installed at the tip of the conical block 24. A blocking plate 27 is installed at the end of the support rod 26 away from the conical block 24. A limiting groove is opened on the side of the blocking block 23 away from the conical hole, and the blocking plate 27 is inserted into the limiting groove. It should be noted that the blocking plate 27 does not block the conical hole.

[0026] The sampling tube 7 has two semi-circular outer tubes 10 on its annular surface. The semi-circular outer tubes 10 are in contact with the annular drill bit 11. Two semi-circular plates 18 are installed at the ends of the semi-circular outer tubes 10. The semi-circular plates 18 are connected to the two semi-circular outer tubes 10 at the same time. The annular inner surfaces of the two semi-circular plates 18 are provided with annular grooves. Meanwhile, multiple annularly spaced air intake slots 19 are provided inside the semi-circular outer cylinder 10, and exhaust slots 20 are provided on both the left and right sides of the air intake slots 19. The air intake slots 19 and exhaust slots 20 both penetrate the semi-circular plate 18. Multiple slots 21 are provided on the upper surface of the semi-circular plate 18. Mounting plates 13 are installed in the multiple slots 21. An air intake pipe 8 communicating with the air compressor is installed on the mounting plate 13. The air intake pipe 8 communicates with the air intake slots 19. A deflection plate 22 is installed between two adjacent blocking blocks 23. The deflection plate 22 and the blocking block 23 are rotatably connected in the annular groove, and the deflection plate 22 and the blocking block 23 are in sliding contact with the exhaust slots 20 and the air intake slots 19.

[0027] It is understandable that when the gas entering the intake groove 19 comes into contact with the blocking block 23, it squeezes the conical block 24, causing the conical block 24 to move downward. When the air in the exhaust groove 20 comes into contact with the blocking block 23, the conical block 24 is pushed upward by the air. At this time, the gas in the exhaust groove 20 passes through the gap between the conical block 24 and the conical hole.

[0028] It should be noted that this application provides a protective structure consisting of a semi-circular outer cylinder 10 and a semi-circular plate 18 on the annular surface of the sampling cylinder 7. This protective structure isolates the outside of the sampling cylinder 7, preventing the sampling cylinder 7 from contacting the sand and gravel on the inner wall of the hole, thereby reducing the rotational friction of the sampling cylinder 7. Furthermore, a deflection structure consisting of a semi-circular ring 25, a blocking block 23, and a deflection plate 22 is installed on the annular surface of the sampling cylinder 7. The gas introduced into the air inlet groove 19 on the semi-circular outer cylinder 10 promotes the rotation of the deflection structure, thereby improving the rotational efficiency of the sampling cylinder 7.

[0029] Furthermore, the annular groove is sealed by the blocking block 23 to prevent air in the air inlet groove 19 from directly entering the exhaust groove 20. Then, a conical hole is opened on the deflection structure, and a one-way structure consisting of a conical block 24, a support rod 26, and a blocking plate 27 is installed in the conical hole. The one-way structure facilitates the passage of air in the exhaust groove 20. When the one-way structure isolates the air inlet groove 19, the air flowing in the air inlet groove 19 compresses the one-way structure to form a downward impact force, which facilitates the sampling tube 7 to drive the annular drill bit 11 to move downward. When the air entering the air inlet groove 19 finally passes through the vertical groove 28 opened on the annular drill bit 11 and is discharged from the exhaust groove 20, it carries away the heat generated by the annular drill bit 11 in the drilling process and excess sand and dust, preventing the accumulation of sand and dust from hindering the descent of the annular drill bit 11.

[0030] In some embodiments, a connecting ring 29 is rotatably connected to the upper surface of the annular drill bit 11. The side of the connecting ring 29 away from the annular drill bit 11 is connected to the semi-circular outer cylinder 10. The annular upper surface of the annular drill bit 11 is provided with a plurality of vertical grooves 28. The air inlet groove 19 and the exhaust groove 20 are both connected to the vertical grooves 28. A transverse groove 12 extending to the upper surface of the annular drill bit 11 is provided in the annular inner surface of the annular drill bit 11. The transverse groove 12 penetrates the vertical grooves 28. An inclined block 16 is slidably connected in the transverse groove 12. The inclined block 16 faces the drill bit 14 in the annular drill bit 11. A circular groove is provided on the side of the inclined block 16 facing the transverse groove 12. An elastic element 17, which is a spring, is installed in the circular groove. The elastic element 17 is in a normal state. A connecting rod 15 is installed at the end of the elastic element 17 facing out of the circular groove. The end of the connecting rod 15 away from the elastic element 17 is installed in the vertical groove 28.

[0031] After sealing the exhaust chute 20, the air entering the intake chute 19 can no longer be discharged through the exhaust chute 20, but only flows out to the outside through the transverse chute 12. This, in turn, squeezes the inclined block 16 to drive the drill bit 14 to move into the annular drill bit 11, cutting off the sample collected in the sampling tube 7, so that the sampling tube 7 can bring the collected sample back to the ground.

[0032] In summary, when using the sampler for mineral geological exploration of this application, firstly, air is introduced into the vertical cylinder 2 through the connecting pipe 9 using an air compressor, which raises the position of the servo motor 5 and connects the annular drill bit 11 to the sampling cylinder 7. Then, the sampling cylinder 7 is connected to the threaded cylinder 6, and the servo motor 5 is started to drive the sampling cylinder 7 to rotate. The rotation of the sampling cylinder 7 drives the annular drill bit 11 to rotate. At this time, the air compressor extracts the air from the vertical cylinder 2 through the connecting pipe 9, which can then drive the servo motor 5 to lower the height again, thereby causing the annular drill bit 11 to move continuously to the ground. Then, air is introduced into the air inlet slot 19 of the semi-circular outer cylinder 10 through the air inlet pipe 8. The air drives the deflection structure, which consists of a semi-circular ring 25, a blocking block 23 and a deflection plate 22, installed on the annular surface of the sampling cylinder 7 to rotate, thereby improving the rotation efficiency of the sampling cylinder 7. At the same time, the semi-circular outer cylinder 10 separates the sampling cylinder 7 from the inner wall of the hole, thereby reducing the rotation friction of the sampling cylinder 7. When air enters the intake slot 19, the air inside the intake slot 19 comes into contact with the deflector plate 22. Since an exhaust slot 20 is provided on both sides of the intake slot 19, when one intake slot 19 comes into contact with the deflector plate 22, the adjacent intake slot 19 comes into contact with the blocking block 23. The air in the intake slot 19 that comes into contact with the deflector plate 22 drives the deflector plate 22 to rotate, improving the rotation efficiency of the sampling tube 7. The air in the intake slot 19 that comes into contact with the blocking block 23 squeezes the blocking block 23, thereby forming a downward impact force, which facilitates the sampling tube 7 to drive the annular drill bit 11 to move downward. After passing through multiple deflector plates 22, the air in the intake slot 19 finally enters the vertical slot 28 of the annular drill bit 11 and is then discharged through the exhaust slot 20, carrying away the heat generated by the annular drill bit 11 during the drilling process and excess sand and dust, preventing the accumulation of sand and dust from hindering the descent of the annular drill bit 11.

[0033] After sampling is completed, the exhaust groove 20 on the uppermost semi-circular outer cylinder 10 is manually sealed. This sealing method can be achieved by using a sealing plug or other tools. At this time, the air entering through the air inlet groove 19 can only enter the outside of the semi-circular outer cylinder 10 through the horizontal groove 12 and is discharged through the gap between the outside of the semi-circular outer cylinder 10 and the hole. Therefore, the air will squeeze the inclined block 16, causing the inclined block 16 to move towards the inner surface of the annular drill bit 11, so that the drill bit 14 contacts the sample collected in the sampling tube 7 and cuts it off. Then, the air compressor is used to introduce air into the vertical cylinder 2 to drive the servo motor 5 to rise in height and remove the sampling tube 7 from the hole.

[0034] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
