Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and more specifically to a drilling sampling device. Background Technology

[0002] Coal is a non-recyclable resource in nature. It is commonly burned for heating, power generation, and metallurgy, making it a valuable resource for human survival. Coal mines are divided into open-pit and underground mines. Since coal mines are generally formed within rock strata, specialized rock drilling equipment is needed to expose the coal hidden within. However, because the distribution of various materials within rock strata is complex, and many rocks are generally harder than coal, drilling rigs can easily be damaged if they collide with the rock. Therefore, during coal mining, it is necessary to sample the components of the coal and rock strata to understand their composition and prevent damage to mining equipment.

[0003] A related technology proposes a drilling device for geological exploration that facilitates sampling. It uses a sampling box to sample the soil, but it cannot avoid the introduction of large particles during the sampling process, which can cause blockages and reduce the efficiency of sampling.

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] The drilling sampling device of this invention includes: a drilling assembly, a driving assembly, a base component 4, and a lifting component 5. The drilling assembly includes a drill bit component 1, a vibration component 2, and a collecting component 3. One end of the drill bit component 1 is connected to one end of the vibration component 2, and the other end of the vibration component 2 is connected to the collecting component 3.

[0038] The vibrating component 2 includes a first rod 201, an eccentric ring 202, a scraper 203, a spring 204, a first ring 205, and a second ring 206. One end of the first rod 201 is connected to the drill bit component 1, and the other end is connected to the collecting component 3. The eccentric ring 202 is sleeved on the end of the first rod 201 adjacent to the drill bit component 1. The scraper 203 is connected to the outer circumferential surface of the eccentric ring 202. The first ring 205, spring 204, and second ring 206 are sequentially sleeved on the first rod 201 in a direction away from the drill bit component 1. One end of the spring 204 is connected to the end of the first ring 205 away from the drill bit component 1, and the other end of the spring 204 is connected to the second ring 206. 5. The second ring 206 is movable in the length direction of the first rod 201. The collecting component 3 includes a collecting cylinder 301, a rotating shaft 302, a second spiral plate 303, a filter cylinder 304, and a third ring 305. The third ring 305 is sleeved on the end of the first rod 201 away from the drill bit component 1. The third ring 305 is connected to one end of the filter cylinder 304, and the other end of the filter cylinder 304 is connected to the collecting cylinder 301. The rotating shaft 302 is located inside the collecting cylinder 301 and is connected to the end of the first rod 201 away from the drill rod 101. The second spiral plate 303 is connected to the outer circumferential surface of the rotating shaft 302 and is spirally arranged in the length direction of the first rod 201.

[0039] One end of the drive component is connected to the drilling component, and the other end of the drive component is connected to the lifting component 5. The lifting component 5 is connected to the base component 4.

[0040] Specifically, such as Figures 1 to 6 As shown, the rear end of the drill bit component 1 is connected to the front end of the vibrating component 2, and the rear end of the vibrating component 2 is connected to the collecting component 3.

[0041] The first rod 201 extends in the front-to-back direction, and its front end is connected to the rear end of the drill bit assembly 1. The drill bit assembly 1 is adapted to penetrate into coal seams or rock formations for drilling. An eccentric ring 202 is located at the front end of the first rod 201. A scraper 203 is connected to the outer circumferential surface of the eccentric ring 202. The scraper 203 can extend along the length of the first rod 201, or it can extend along the circumference of the first rod 201, i.e., it extends in the front-to-back direction. Alternatively, there can be multiple scrapers 203, with some extending along the length of the first rod 201 and others extending along the circumference of the first rod 201.

[0042] This facilitates scraping the inner wall after drilling, and as the particles move backward during drilling, the eccentric ring 202 and scraper 203 stir and impact the particles, crushing them.

[0043] A first ring 205 is fitted onto the front end of a first rod 201, a second ring 206 is fitted onto the rear end of the first rod 201, and a spring 204 is fitted onto the first rod 201, with its front end connected to the first ring 205 and its rear end connected to the second rod. The first ring 205 and the second ring 206 are movable in the front-rear direction. When a large particle impacts the first ring 205, the first ring 205 is forced to move backward, and the spring 204 contracts. At this time, the rear end of the second ring 206 moves backward to impact and crush the large particle. When the second ring 206 moves backward and contacts the collecting component 3, the spring 204 is compressed again, and the first ring 205 impacts forward to crush the large particle. The collecting component 3 is suitable for collecting object particles, such as rock particles and coal seam particles. The radial dimension of the eccentric ring 202 is larger than that of the first ring 205 and the second ring 206, and the radial dimension of the third ring 305 is at least partially smaller than that of the second ring 206.

[0044] The drive assembly is connected to the drilling assembly to drive the drill bit 1 to rotate, thereby facilitating drilling into the coal seam or rock strata. The vibration assembly is suitable for impact crushing large particles. Since the vibration assembly is equipped with an eccentric ring 202 and a scraper 203, the first rod 201 and the drilling assembly vibrate continuously in the up-down or left-right directions during rotation, thereby impacting the particles and facilitating the movement of the particles to the rear end. The collection assembly 3 is suitable for collecting the particles.

[0045] The rotating shaft 302 extends in the front-to-back direction, and its front end is connected to the rear end of the first rod 201. The rotating shaft 302 is located inside the collecting cylinder 301. The second spiral plate 303 is connected to the outer circumferential surface of the rotating shaft 302, and the second spiral plate 303 is spirally arranged on the rotating shaft 302 in the front-to-back direction. The front end of the filter cylinder 304 is connected to the third ring 305, and the filter cylinder 304 is connected to the front end of the collecting cylinder 301. The third ring 305 is sleeved on the first rod 201. The radial dimension of the front end of the third ring 305 is smaller than that of the second ring 206, and the radial dimension of the rear end of the third ring 305 is at least partially greater than or equal to the radial dimension of the second ring 206. Therefore, the second ring 206 moves back and forth... When in motion, the particles on the third ring 305 can be impacted, causing them to move backward. This gives larger particles the potential energy to move backward. At this time, the filter cylinder 304 can be at least partially located outside the borehole of the coal seam or rock stratum. Large particles under the impact of the third ring 305 and the second ring 206 fall out of the borehole, preventing large particles from directly impacting the filter cylinder 304. The drive assembly is connected to the rotating shaft 302 to make the rotating shaft 302 rotate, thereby conveying the filtered particles into the collection cylinder 301. The rear end of the collection cylinder 301 is provided with a discharge port 306, which facilitates the operator to collect the objects in the collection cylinder 301.

[0046] The lower end of the lifting component 5 is connected to the base component 4, and the lower end of the base component 4 is in contact with the ground. The lifting component 5 rises or falls in the vertical direction, which in turn drives the drive component 8 to rise or fall in the vertical direction, making it convenient for operators to sample coal seams or rock strata at different heights.

[0047] The borehole sampling device of this invention, by setting an eccentric ring 202 and a scraper 203, is adapted to impact the particles, thereby crushing large-sized particles. During operation, the eccentric ring 202 causes the drill bit component 1, the first rod 201, and the rotating shaft 302 to vibrate in the vertical and horizontal directions, preventing objects from sticking to the first rod 201, the rotating shaft 302, or the drill bit component 1, thus avoiding blockage. The vibration also facilitates the movement of objects out of the borehole, improving collection efficiency. The filter cylinder 304 filters the objects, preventing large particles from entering the collection cylinder 301 and causing blockage. Simultaneously, the vibration prevents large particles from continuously impacting the filter cylinder 304, avoiding filter clogging. Therefore, sampling of coal seams or rock strata can be performed simultaneously with drilling, improving the efficiency of borehole sampling.

[0048] Furthermore, the drilling sampling device also includes a bearing component, which is sleeved on the front end of the rotating shaft 302. The front end of the bearing component is connected to the rear end of the filter screen cylinder, and the rear end of the bearing component is connected to the collection cylinder. This allows the filter screen cylinder to rotate relative to the rotating shaft and the collection cylinder, preventing damage to the filter screen cylinder due to stress. It also increases the vibration and rotation of large particles between the borehole and the drilling sampling device, reducing the probability of clogging and improving the stability and safety of the drilling sampling equipment.

[0049] In other embodiments, spring 204 includes a first spring 204 and a second spring 204, which are spaced apart in the front-rear direction. A first ring 205 is located at the front end of the first rod 201, and a second ring 206 is located at the rear end of the first ring 205. The first spring 204 is sleeved on the first rod 201, and its rear end is connected to the first rod 201, while its front end is connected to the first ring 205. The second spring 204 is sleeved on the first rod 201, and its rear end is connected to the second ring 206. Thus, the front-rear movement of the first ring 205 and the front-rear movement of the second ring 206 separate them, facilitating the direct extension of the first ring 205 after compression. This allows the particles to directly impact the vibration area of ​​the eccentric ring 202 and the scraper 203, improving the crushing efficiency of the particles. Furthermore, it limits the movement of the first ring 205, enhancing the stability and safety of the drilling and sampling equipment.

[0050] In some embodiments, the drill bit component 1 includes a drill rod 101 and a first spiral plate 102. The first spiral plate 102 is connected to the outer peripheral surface of the drill rod 101 and is spirally arranged in the length direction of the first rod 201. The drill rod 101 is connected to the end of the first rod 201 away from the collecting component 3.

[0051] Specifically, such as Figures 1 to 5 As shown, the drill rod 101 moves in the front-back direction. The rear end of the drill rod 101 is connected to the front end of the first rod 201. The first spiral plate 102 is connected to the outer circumferential surface of the drill rod 101, and the first spiral plate 102 is spirally arranged on the drill rod 101 in the front-back direction. It can be understood that the drill rod 101 can be detachably connected to the first rod 201, and the first rod 201 can be detachably connected to the rotating shaft 302, which facilitates the replacement of the drill rod 101 or the vibration component. After collection, the first rod 201 can be disassembled to facilitate the processing of the objects in the collection cylinder 301, which improves the convenience of the drilling sampling equipment.

[0052] In some embodiments, the radial dimension of the first ring 205 gradually decreases in the direction away from the drill bit component 1, the radial dimension of the second ring 206 gradually increases in the direction away from the drill bit component 1, the radial dimension of the filter cylinder 304 gradually increases in the direction away from the drill bit component 1, the radial dimension of the drill rod 101 is greater than the radial dimension of the first rod 201, and the radial dimension of the first rod 201 is greater than the radial dimension of the collecting cylinder 301.

[0053] Specifically, such as Figures 1 to 5 As shown, the radial dimension of the first ring 205 gradually decreases from front to back, facilitating the movement of particles towards the rear. The radial dimension of the second ring 206 gradually increases from front to back, facilitating the impact of particles at the front onto the second ring 206. After impact, the second ring 206 contracts forward and then extends, increasing the rate of forward and backward movement of the object. This increased movement rate improves sampling and collection efficiency. The radial dimension of the first rod 201 is larger than that of the collection cylinder 301, meaning there is a predetermined gap between the inner wall of the borehole and the outer wall of the collection cylinder 301.

[0054] Furthermore, the first ring 205 is made of magnetic material, and the second ring 206 is made of magnetic material. The magnetic poles of the first ring 205 and the second ring 206 are opposite in the front-back direction, thereby increasing the mechanical energy when the first ring 205 and the second ring 206 approach each other, increasing the impact force of the first ring 205 and the second ring 206, impacting large particles to make large particles around the first rod 201 move forward into the vibration area of ​​the eccentric ring 202, or to discharge large particles around the collection cylinder 301 from the borehole to avoid blockage, thereby improving the efficiency of the borehole sampling equipment.

[0055] In some embodiments, the base component 4 includes a base plate 401, a first electric cylinder 402, a fixing plate 403, fixing nails 404, and sliding wheels 405. Sliding wheels 405 are installed on all four sides of the bottom end of the base plate 401, the first electric cylinder 402 is installed in the middle of the top end of the base plate 401, and a plurality of fixing nails 404 are fixedly connected to the bottom end of the fixing plate 403.

[0056] Specifically, such as Figures 1 to 5 As shown, the lower end of the base plate 401 is connected to the sliding wheel 405, which facilitates the movement of the base plate 401. The first electric cylinder 402 is connected to the upper end of the base plate 401, and the first electric cylinder 402 passes through the base plate 401 in the vertical direction and is connected to the fixing plate 403. The lower end of the fixing plate 403 is fixedly connected with multiple fixing nails 404. The first electric cylinder 402 extends and retracts in the vertical direction to make the fixing nails 404 extend into or away from the ground. In this way, the first electric cylinder 402 extends and retracts to fix the base component 4 on the ground, thereby improving the stability and safety of the drilling and sampling equipment.

[0057] Furthermore, the base component 4 also includes multiple limiting plates 406, which extend in the front-to-back direction. The left and right sides of the fixing plate 403 are in contact with the limiting plates 406, and the upper end of the limiting plates 406 is connected to the fixing plate 403, thereby limiting the vertical movement of the fixing plate 403 and improving the stability and safety of the drilling and sampling equipment.

[0058] In some embodiments, the lifting component 5 includes a sliding frame 501, a lifting plate 502, a second electric cylinder 503, a mounting frame 504, a first motor 505, a threaded rod 506, a moving bar 507, and a moving rod 508.

[0059] The sliding frame 501 is connected to the end of the base plate 401 away from the ground. A second electric cylinder 503 is installed inside the sliding frame 501. The output end of the second electric cylinder 503 is fixedly connected to one end of the lifting plate 502. The other end of the lifting plate 502 is connected to the drive assembly. The sliding frame 501 is connected to the mounting frame 504. A threaded rod 506 is provided inside the mounting frame 504. A first motor 505 is installed at the end of the mounting frame 504 away from the sliding frame 501. The output end of the first motor 505 is fixedly connected to the threaded rod 506. A moving strip 507 is slidably connected to the inner wall of the mounting frame 504. One end of the moving strip 507 is connected to a moving rod 508. A fixing pad 509 is fixedly connected between the ends of the moving rods 508.

[0060] Specifically, such as Figures 1 to 5As shown, there can be two lifting components 5, which are arranged opposite each other at the left and right ends of the base plate 401. The sliding frame 501 is connected to the upper end of the base plate 401. A second electric cylinder 503 is installed on the inner bottom wall of the sliding frame 501. The lower end of the lifting plate 502 extends into the sliding frame 501. The output end of the second electric cylinder 503 is fixedly connected to the lower end of the lifting plate 502. The second electric cylinder 503 extends and retracts in the vertical direction so that the lifting plate 502 can move relative to the sliding frame 501 in the vertical direction.

[0061] The front end of the sliding frame 501 is connected to the mounting frame 504. A threaded rod 506 is provided inside the mounting frame 504. A first motor 505 is mounted on one end of the mounting frame 504. The output end of the first motor 505 is fixedly connected to the threaded rod 506. A moving strip 507 is slidably connected to the inner wall of the mounting frame 504. The moving strip 507 is connected to a moving rod 508, which is connected to a fixing pad 509. The moving strip 507 is threadedly connected to the threaded rod 506, thereby causing the first motor 505 to drive the threaded rod 506 to move within the mounting frame 504. The frame 504 rotates, causing the moving bar 507 to move relative to the threaded rod 506 in the left-right direction, which in turn causes the fixing pad 509 to move in the left-right direction. It is understood that there can be multiple lifting components 5, for example, two lifting components 5 arranged at the left and right ends of the base plate 403. This facilitates the fixing of the drilling sampling device within the tunnel after the two fixing pads 509 extend and contact the inner wall of the tunnel, thereby improving the stability and safety of the drilling sampling device during sampling. The fixing pad 509 includes a plate and a nail. The nail is connected to the plate, and the plate is connected to the moving rod 508, thereby increasing the friction between the fixing pad 509 and the inner wall of the tunnel during use, and improving the stability and safety of the drilling sampling device.

[0062] The borehole sampling device of this invention, by setting up the lifting component 5, can change the position of the driving component in the vertical direction, thereby facilitating the operator to sample coal seams or rock strata in different locations and areas, and improving the convenience of the borehole sampling equipment.

[0063] Furthermore, the drilling and sampling device also includes multiple angle adjustment components 6 and multiple lifting components 5. The lower end of the lifting component 5 is connected to the upper end of the base plate 401, and the upper end of the lifting component 5 is connected to the angle adjustment component 6. Lifting components 5 are provided on both the left and right ends of the upper surface of the base component 4. Multiple angle adjustment components 6 and multiple lifting components 5 are connected one-to-one, that is, the angle adjustment components 6 and the lifting components 5 are arranged on the left and right ends of the upper surface of the base plate 401.

[0064] In some embodiments, the angle adjustment component 6 includes an arc-shaped frame 601, an arc-shaped toothed belt 602, and a second motor 603. The lifting plate 502 includes an arc-shaped groove, and the arc-shaped frame 601 is at least partially disposed in the arc-shaped groove. The arc-shaped frame 601 is slidably connected between the top ends of the two lifting plates 502. An arc-shaped toothed belt 602 is fixedly sleeved on one side of the outer wall of the arc-shaped frame 601. A drive gear meshes on the arc-shaped toothed belt 602. One end of the sliding frame 501 away from the base plate 401 is connected to the second motor 603. The drive gear is fixedly sleeved on the output end of the second motor 603.

[0065] Specifically, such as Figures 1 to 5 As shown, the angle adjustment component 6 includes an arc-shaped frame 601, which is at least partially disposed within an arc-shaped groove. The arc-shaped frame 601 is rotatable relative to the lifting plate 502 and is slidably connected between the top ends of the two lifting plates 502. That is, the arc-shaped frames 601 at the left and right ends are respectively at least partially disposed within the corresponding arc-shaped grooves at the left and right ends, and the arc-shaped frames 601 at the left and right ends are respectively connected to the drive assembly.

[0066] An arc-shaped toothed belt 602 is fixedly fitted onto one side of the outer wall of the arc-shaped frame 601. A drive gear meshes with the arc-shaped toothed belt 602. The upper end of one of the sliding frames 501 is connected to the second motor 603. The drive gear is fixedly fitted onto the output end of the second motor 603. When the second motor 603 is turned on, it drives the arc-shaped frame 601 to rotate relative to the lifting plate 502. For example, the arc-shaped frame 601 rotates relative to the lifting plate 502 in the vertical direction, which facilitates the operator to adjust the position of the arc-shaped frame 601 in the vertical direction. When there are two angle adjustment components 6 and two lifting components 5, and they are arranged at the left and right ends of the base plate 401, the two arc-shaped frames 601 are respectively connected to the drive assembly, thereby improving the stability and safety of the arc-shaped frame 601 during rotation. The drive gear is a gear in the prior art.

[0067] In some embodiments, the movable component 7 includes a movable frame 701, a movable plate 702, a screw 703, a third motor 704, a connecting plate 706, and a fixed base 705. The movable frame 701 is connected to the arc-shaped frame 601. The screw 703 is rotatably connected between the inner walls of the two sides of the movable frame 701. The third motor 704 is installed on one side of the movable frame 701. The output end of the third motor 704 is fixedly connected to the screw 703. The movable plate 702 is slidably connected to the inner wall of the movable frame 701. The movable plate 702 and the screw 703 are threadedly connected. A groove is provided on one side of the movable frame 701. The connecting plate 706 is fixedly connected to one end of the movable plate 702. One end of the connecting plate 706 passes through the groove and is connected to the fixed base 705. The fixed base 705 is slidably disposed at the top of the movable frame 701.

[0068] Specifically, such as Figures 1 to 5As shown, the movable frame 701 is connected to the arc-shaped frame 601. For example, when there are two angle adjustment components 6 and two lifting components 5, and they are arranged at the left and right ends of the base plate 401, the two arc-shaped frames 601 are respectively connected to the movable frame 701. A screw 703 is provided inside the movable frame 701. A third motor 704 is connected to the rear end of the movable frame 701, and the output end of the third motor 704 passes through the movable frame 701 and is connected to the screw 703 so that the screw 703 rotates inside the movable frame 701, thereby causing the movable plate 702 to move in the front-back direction. A connecting plate 706 passes through a slide groove and is connected to the movable plate 702. A fixed seat 705 is connected to the connecting plate 706. The fixed seat 705 is located above the upper end face of the movable frame 701. The fixed seat 705 can contact the upper end face of the movable frame 701, and the fixed seat 705 can move relative to the movable frame 701 in the front-back direction.

[0069] When the movable plate 702 moves in the front-to-back direction within the movable frame 701, the movable plate 702 drives the fixed base 705 to move in the front-to-back direction via the connecting plate 706.

[0070] When the height and angle of the moving frame 701 need to be adjusted, the two second electric cylinders 503 are activated to push the corresponding lifting plate 502 to rise and fall longitudinally on the corresponding sliding frame 501, thereby adjusting the height of the moving frame 701. The first motor 505 is activated to drive the corresponding threaded rod 506 to make the moving bar 507 slide in the mounting frame 504, so that the moving rod 508 fixedly connected to one end of the moving bar 507, and the fixing pad 509 fixedly connected to one end of the moving rod 508, come into contact with the inner wall of the tunnel, thereby further ensuring the stability of the bottom plate 401 and various components during drilling operations. At the same time, the second motor 603 is activated to drive the arc frame 601 to rotate in the arc groove in the vertical direction, thereby adjusting the angle of the moving frame 701 to control the drilling direction.

[0071] In some embodiments, the driving component 8 includes a meshing sleeve 801, a rotating shaft 802, a frame rod 803, a rotating seat 804, and a driving member 805.

[0072] Specifically, such as Figures 1 to 5As shown, the lower end of the rotating seat 804 is connected to the lower end of the fixed seat 705. The driving member 805 is connected to the rear end of the rotating seat 804, and the output end of the driving member 805 is connected to the rear end of the rotating shaft 802. The rotating shaft 802 passes through the rotating seat 804 and is connected to the rear end of the meshing sleeve 801. The front end of the meshing sleeve 801 is connected to the rear end of the rotating shaft 302. It can be understood that the rotating seat 804 has a through hole to facilitate the connection between the transmission shaft and the meshing sleeve 801. The meshing sleeve 801 is connected to the rotating shaft 302, thereby facilitating the driving member 805 to drive the rotating shaft 302, the first rod 201, and the drill rod 101 in the drilling assembly to rotate. The outer circumferential surface of the collecting cylinder 301 is connected to the frame rod 803, which is also connected to the rotating seat 804, or the frame rod 803 is also connected to the fixed seat 705, thereby fixing the collecting cylinder 301. When the collecting cylinder 301 rotates...

[0073] Furthermore, the frame rod 803 includes a first rod body, a second rod body, and a third rod body. The first rod body is at least partially sleeved on the collecting cylinder 301 and connected to the outer peripheral surface of the collecting cylinder 301. The first rod body is connected to the second rod body and the third rod body respectively. The second rod body is connected to the rotating seat 804, and the third rod body is connected to the fixed seat 705, thereby improving the stability of the collecting cylinder 301.

[0074] In some embodiments, the drilling sampling device further includes a collection bottle 9 and a collection tube, the inlet of which is connected to one end of the collection cylinder 301 adjacent to the drive assembly, and the outlet of which is connected to the collection bottle 9.

[0075] Specifically, such as Figures 1 to 5 As shown, the collection bottle 9 is connected to the inlet and the outlet of the collection tube. The inlet of the collection tube is connected to the collection cylinder 301 to discharge the object particles into the collection tube, and then discharge the object particles into the collection bottle 9. The collection bottle 9 can be arranged at the rear end of the base plate 401, or at the front end of the moving frame 701, or at the upper end of the arc frame 601 or inside the arc frame 601. By setting the collection tube and the collection bottle 9, the object particles can be collected, which facilitates the preservation of the drilled samples.
