Description

Technical Field

[0001] The present invention relates to the technical field of resource exploration, and in particular to a device for prospecting and exploration of solid mineral resources. Background Art

[0002] Solid mineral resources are natural solid enrichments with economic significance formed by geological processes in the earth's crust or on the surface, including coal, oil shale, stone coal, natural asphalt, uranium and thorium in energy minerals. The rational exploration, mining and protection of solid mineral resources are of great significance to human survival and development.

[0003] In existing resource exploration technology, rock and soil sampling equipment is usually used for resource exploration. The existing rock and soil sampling equipment is usually composed of a drill bit and a hollow drill rod. The operator uses the drill bit to drill a hole, and at the same time drives the drill rod to extend into the rock formation. The drill bit cuts the rock and soil to form a rock column, which is located in the drill rod. After the drilling work is completed, the operator relies on the friction between the rock column and the inner wall of the drill rod to engage the rock column with the inner wall of the drill rod, thereby removing it from the formation. However, this sampling method relies solely on the friction of the inner wall of the drill rod, which can easily cause the rock column to fall off, resulting in sampling failure.

[0004] In summary, solving the problem of existing rock and soil sampling equipment relying solely on friction on the inner wall of the drill pipe, which easily causes rock pillars to fall off and leads to sampling failure, has become a difficult problem that needs to be solved in the field. Therefore, it is necessary to provide a device that can more automatically clamp and fix rock pillars for solid mineral resource prospecting and exploration. Summary of the Invention

[0005] To solve the above problems, the present invention provides a device for prospecting and exploration of solid mineral resources. Through the design of the clamping component, the sampled samples can be stably clamped after sampling is completed, effectively reducing the risk of sample falling off and improving the success rate of sampling.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a device for prospecting and exploration of solid mineral resources, comprising a base and a sampling tube, a drill bit is coaxially fixedly connected to the bottom of the sampling tube, and a clamping assembly for clamping the sample is provided in the sampling tube.

[0007] The clamping assembly includes a central rod fixedly connected to the top wall of the sampling barrel, a plurality of hinged rods are hinged at the lower end of the central rod, a clamping plate is hinged at the lower end of the hinged rods, a plurality of springs are fixedly connected to the clamping plates, and the ends of the springs away from the clamping plates are fixedly connected to the inner wall of the sampling barrel; a separation assembly for separating the sample from the formation and a support assembly for supporting the sample are provided at the bottom of the clamping plate; an auxiliary assembly for assisting the rotation of the drill bit is provided in the sampling barrel.

[0008] The base is provided with a rotating assembly for driving the sampling barrel to rotate, a lifting assembly for driving the sampling barrel to lift and a positioning assembly for assisting the drill bit to position; a sampling hole for the drill bit and the sampling barrel to pass through is opened on the base.

[0009] The technical principles of the above solution are as follows:

[0010] The designated sampling point is located using the positioning assembly. The sampling barrel and drill bit are rotated by the rotating assembly, and then gradually lowered by the lifting assembly to begin drilling and sampling. As the sampling barrel rotates, it drives the center rod and hinged rod to rotate together, and the hinged rod drives the clamping plate to rotate. Due to the centrifugal force, when the centrifugal force on the clamping plate exceeds the spring force, the clamping plate moves away from the axis of the sampling barrel, compressing the spring. At the same time, the auxiliary assembly lubricates and cools the drill bit.

[0011] During the drilling sampling process, the sample will enter the sampling cylinder from the bottom of the sampling cylinder. After the drilling is completed, the rotation of the sampling cylinder and the drill bit is stopped by the rotating assembly. The centrifugal force on the clamping plate disappears, and the spring will immediately rebound, pushing the clamping plate toward the axis of the sampling cylinder, so that the sample is clamped and fixed by the clamping plate. At the same time, the separation assembly will separate the sample from the formation, and the lifting assembly will bring the sampling cylinder and the drill bit back to the ground to complete the sampling work.

[0012] The above scheme has the following beneficial effects:

[0013] 1. In existing resource exploration techniques, when sampling, operators rely on friction between the sample and the inner wall of the drill pipe to engage the sample and remove it from the formation. However, this rock column extraction method, relying solely on friction with the inner wall of the drill pipe, can easily cause the rock column to fall off, resulting in sampling failure. The clamping assembly design of the present invention can stably clamp the sample, significantly reducing the risk of sample loss and improving the sampling success rate.

[0014] 2. In the present invention, when sampling, the clamping plate will use the centrifugal force generated by the rotation of the sampling cylinder to move closer to the edge of the sampling cylinder, avoiding occupying the sampling space of the sampling cylinder, so that the sample can enter the sampling cylinder through the bottom of the sampling cylinder. When the sampling cylinder stops rotating, the clamping plate will immediately reset, thereby quickly clamping the sample to prevent the sample from falling off; without designing additional driving parts, the sampling and clamping functions can be automatically realized, which greatly reduces the preparation cost of the device.

[0015] 3. In the prior art, when the drill bit and drill rod are retracted to the ground, the drill rod and drill bit will collide with the rock wall, causing the sample in the drill rod to loosen, which can easily cause the sample to fall off. The present invention uses the design of the clamping plate and the spring, that is, when the sampling tube and the drill bit collide with the rock wall, the spring will weaken the external force generated by the collision and keep the clamping plate and the sample in contact, thereby reducing the risk of the sample falling off.

[0016] Furthermore, the separation component includes a plurality of cutter heads, each of which is fixedly connected to the bottom of the adjacent clamping plate, and the bottom of the cutter head is inclined toward the middle of the sampling tube.

[0017] Beneficial effect: When the clamping plate clamps the sample, the cutter heads will also move closer to each other. Since the bottom of the cutter heads are inclined toward the middle of the sampling tube, the cutter heads will squeeze the sample, causing the stress between the sample and the formation to increase, thereby effectively separating the sample from the formation and facilitating the subsequent bringing of the sample back to the ground.

[0018] Furthermore, the auxiliary components include several piston chambers opened in the sampling cylinder, and the piston chambers store auxiliary liquid for reducing the temperature of the drill bit and the friction between the drill bit and the formation; the piston chambers are laterally slidably fitted with piston plates, and the piston plates are hinged to the side of the clamping plate close to the piston plate, and the piston rods are hinged to the side of the piston rods away from the piston plate, and the connecting rods are hinged to the clamping plate adjacent to the piston rod at one end; the piston chambers are opened on the side away from the clamping plate with several drainage holes; the piston chambers are connected to the first one-way valve for air intake on the side away from the drainage holes.

[0019] Beneficial effects: During the drilling process, the drill bit temperature will rise sharply due to the friction between the drill bit and the rock wall. Excessive temperature of the drill bit will affect the service life of the drill bit. Through the design of the piston cavity, during the drilling process, the piston cavity will transport auxiliary fluid to the drill bit to lubricate and cool the drill bit, thereby increasing the service life of the drill bit.

[0020] Furthermore, the support assembly includes several extension grooves opened in the sampling tube, and support rods are laterally slidably fitted in the extension grooves; the bottom of the piston cavity is connected to the extension grooves adjacent to it, and the connection between the two is connected to a second one-way valve for transporting gas to the extension grooves.

[0021] Beneficial effect: The support rod can support the bottom of the sample, further preventing the sample from falling out of the sampling tube, and effectively improving the success rate of sampling.

[0022] Furthermore, the lifting assembly includes a lifting platform, the rotating assembly is installed at the bottom of the lifting platform, and the sampling tube is installed at the bottom of the rotating assembly; a first driving member is fixedly connected to the base, the output shaft of the first driving member is fixedly connected to a threaded rod, and the lifting platform and the threaded rod are threaded together; a limiting assembly for limiting the lifting platform is provided on the base; the controller is used to control the operation of the first driving member, and then control the rotation of the threaded rod.

[0023] Beneficial effect: The lifting platform can effectively adjust the height of the sampling tube and the drill bit, so that the drill bit and the sampling tube can enter the formations of different depths.

[0024] Furthermore, the limiting assembly includes a plurality of limiting rods fixedly connected to the top of the base, and the limiting rods all pass through the lifting platform and are vertically slidably engaged therewith.

[0025] Beneficial effect: The limiting rod can limit the lifting platform, so that the lifting platform can move up and down under the drive of the threaded rod, thereby adjusting the height of the sampling tube and the drill bit.

[0026] Furthermore, the rotating assembly includes a second driving member fixedly connected to the bottom of the lifting platform, and the output shaft of the second driving member is fixedly connected to the top of the sampling cylinder; the controller is used to control the operation of the second driving member, thereby controlling the rotation of the sampling cylinder.

[0027] Beneficial effect: The second driving member is started by the controller, and the output shaft of the second driving member drives the sampling tube and the drill bit to rotate, thereby enabling the drill bit to perform drilling work.

[0028] Furthermore, a scraper ring is vertically slidably fitted in the sampling tube, a rotating rod is hinged on the top of the scraper ring, and the top of the hanging rod is fixedly connected to the clamping plate adjacent thereto.

[0029] Beneficial effect: When the scraper ring moves up and down, it cleans the rock and soil around the extension slot to prevent the rock and soil from blocking the extension slot, which would cause the support rod to be unable to extend outside the extension slot to support the sample.

[0030] Furthermore, the positioning component includes an infrared lamp fixedly connected to the bottom of the lifting platform, and the controller is used to control the operation of the infrared lamp.

[0031] Beneficial effect: The infrared lamp is activated through the controller, and the point illuminated by the infrared lamp represents the drilling point of the drill bit. In this way, the operator can adjust the drilling point of the drill bit according to the point illuminated by the infrared lamp, thereby improving the convenience of operation and the accuracy of drilling.

[0032] Furthermore, an anti-slip layer is fixedly connected to the clamping plates.

[0033] Beneficial effect: The anti-slip layer can increase the friction between the clamping plate and the sample, further preventing the sample from falling off.

[0034] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following is further described in detail through specific implementation methods:

[0041] Example 1:

[0042] As attached Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown: A device for prospecting and exploration of solid mineral resources includes a base 1 and a sampling tube 2. A drill bit 3 is fixedly connected to the bottom of the sampling tube 2 by a coaxial bolt, and a clamping component for clamping a sample is provided in the sampling tube 2.

[0043] like Figure 2 and Figure 3 As shown, the clamping assembly includes a center rod 4 fixedly connected to the inner top wall of the sampling tube 2 with bolts, a plurality of hinged rods 5 are hinged at the lower end of the center rod 4, and a clamping plate 6 is hinged at the lower end of the hinged rod 5. A plurality of springs 7 are fixedly connected to the clamping plate 6 with screws, and the ends of the springs 7 away from the clamping plate 6 are fixedly connected to the inner wall of the sampling tube 2 with screws; a separation assembly for separating the sample from the formation and a support assembly for supporting the sample are provided at the bottom of the clamping plate 6; an auxiliary assembly for assisting the rotation of the drill bit 3 is provided in the sampling tube 2.

[0044] The base 1 is provided with a rotating assembly for driving the sampling barrel 2 to rotate, a lifting assembly for driving the sampling barrel 2 to rise and fall, and a positioning assembly for assisting the drill bit 3 in positioning; a sampling hole for the drill bit 3 and the sampling barrel 2 to pass through is opened on the base 1.

[0045] Specifically, when the sampling barrel 2 is driven to rotate by the rotating assembly, the sampling barrel 2 will drive the center rod 4 and the hinge rod 5 to rotate together, and the hinge rod 5 will drive the clamping plate 6 to rotate. Due to the effect of centrifugal force, when the centrifugal force on the clamping plate 6 is greater than the elastic force of the spring 7, the clamping plate 6 will move away from the axis of the sampling barrel 2, and the spring 7 will be compressed. At the same time, the auxiliary assembly will lubricate and cool the drill bit 3. During the drilling sampling process, the sample will enter the sampling barrel 2 from the bottom of the sampling barrel 2. After the drilling is completed, the rotation of the sampling barrel 2 and the drill bit 3 is stopped by the rotating assembly. The centrifugal force on the clamping plate 6 disappears, and the spring 7 will immediately rebound, pushing the clamping plate 6 toward the axis of the sampling barrel 2, so that the sample is clamped and fixed by the clamping plate 6. At the same time, the separation assembly will separate the sample from the formation, and the lifting assembly will bring the sampling barrel 2 and the drill bit 3 back to the ground, completing the sampling work.

[0046] The clamping plates 6 are all fixedly bonded with an anti-skid layer, which can increase the friction between the clamping plates 6 and the sample, further preventing the sample from falling off.

[0047] like Figure 2 and Figure 3 As shown, the separation assembly includes a plurality of cutter heads 8 , each of which is fixedly connected to the bottom of the adjacent clamping plate 6 by bolts, and the bottom of the cutter heads 8 is inclined toward the middle of the sampling tube 2 .

[0048] Specifically, when the clamping plate 6 clamps the sample, the cutter heads 8 will also move closer to each other. Since the bottoms of the cutter heads 8 are inclined toward the middle of the sampling tube 2, the cutter heads 8 will squeeze the sample, causing the stress between the sample and the formation to increase, thereby effectively separating the sample from the formation, making it easier to bring the sample back to the ground later.

[0049] like Figure 2 As shown, the auxiliary component includes several piston chambers opened in the sampling tube 2, and the piston chambers store auxiliary liquid for reducing the temperature of the drill bit 3 and the friction between the drill bit 3 and the formation; the piston chambers are laterally slidably fitted with piston plates 9, and the piston plates 9 are hinged with piston rods 10 on the side close to the clamping plate 6, and the piston rods 10 are hinged with connecting rods 11 on the side away from the piston plate 9, and the connecting rods 11 are hinged to the clamping plate 6 adjacent to the piston rod 10 on the side away from the piston rod 10; the piston chambers are opened with several drainage holes on the side away from the clamping plate 6; the piston chambers are connected to the first one-way valve 12 for air intake on the side away from the drainage holes.

[0050] Specifically, when the clamping plate 6 moves toward the edge of the sampling tube 2 under the action of centrifugal force, the clamping plate 6 pushes the connecting rod 11 and the piston rod 10 into the piston cavity, which in turn pushes the piston plate 9 to transport the auxiliary liquid in the piston cavity through the drainage hole to the space between the sampling tube 2 and the rock wall. The auxiliary liquid flows to the drill bit 3 due to gravity, cooling and lubricating the drill bit 3. During the drilling process of the drill bit 3, the temperature of the drill bit 3 will rise sharply due to friction between the drill bit 3 and the rock wall. Excessive temperature of the drill bit 3 will affect the service life of the drill bit 3. Through the design of the auxiliary liquid, the auxiliary liquid will lubricate and cool the drill bit 3 during the drilling process, thereby extending the service life of the drill bit 3.

[0051] like Figure 2 As shown, the support assembly includes several extension grooves opened in the sampling tube 2, and support rods 13 are laterally slidably fitted in the extension grooves; the bottom of the piston cavity is connected to the extension grooves adjacent to it, and the connection between the two is connected to a second one-way valve 14 for delivering gas to the extension grooves.

[0052] Specifically, when the sampling tube 2 stops rotating, the clamping plate 6 will reset under the action of the spring 7, and then pull the connecting rod 11 and the piston rod 10 closer to the clamping plate 6. The piston rod 10 will pull the piston plate 9 to slide in the direction of the clamping plate 6 in the piston box, and then the gas in the piston cavity will be transported to the extension groove through the second one-way valve 14, and the support rod 13 will be blown out of the extension groove to support the bottom of the sample, further preventing the sample from falling off from the sampling tube 2, and effectively improving the success rate of sampling.

[0053] like Figure 1 As shown, the lifting assembly includes a lifting platform 15, the rotating assembly is installed at the bottom of the lifting platform 15, and the sampling tube 2 is installed at the bottom of the rotating assembly; the base 1 is fixedly connected with a first motor 16 with bolts. In this embodiment, the first motor 16 is a reduction motor and is named the first motor 16; the output shaft of the first motor 16 is fixedly connected with a threaded rod 17 with bolts, and the lifting platform 15 is threadedly matched with the threaded rod 17; the base 1 is provided with a limiting assembly for limiting the lifting platform 15; the controller is used to control the operation of the first motor 16, and then control the rotation of the threaded rod 17.

[0054] The limiting assembly includes several limiting rods 18 bolted to the top of the base 1. Each limiting rod 18 extends through the lifting platform 15 and slides vertically with it. The limiting rods 18 can limit the position of the lifting platform 15, allowing the lifting platform 15 to move up and down driven by the threaded rod 17, thereby adjusting the height of the sampling tube 2 and the drill bit 3.

[0055] Specifically, the operator starts the first motor 16 through the controller, and the output shaft of the first motor 16 will drive the threaded rod 17 to rotate. Since the lifting platform 15 is limited by the limiting rod 18, and since the lifting platform 15 and the threaded rod 17 are threaded together, the rotation of the threaded rod 17 will drive the lifting platform 15 to move vertically, thereby adjusting the height of the sampling tube 2 and the drill bit 3, so that the drill bit 3 and the sampling tube 2 can enter the formations at different depths.

[0056] The rotating assembly includes a second motor 19 fixedly connected to the bottom of the lifting platform 15 by bolts. In this embodiment, the second motor 19 is a reduction motor and is named the second motor 19; the output shaft of the second motor 19 is fixedly connected to the top of the sampling tube 2 by bolts; the controller is used to control the operation of the second motor 19, thereby controlling the rotation of the sampling tube 2.

[0057] The positioning assembly includes an infrared lamp (not shown in the figure) fixedly connected to the bottom of the lifting platform 15 by bolts, and the controller is used to control the operation of the infrared lamp.

[0058] Specifically, the operator starts the infrared lamp through the controller, and the point illuminated by the infrared lamp represents the drilling point of the drill bit 3. In this way, the operator can adjust the drilling point of the drill bit 3 according to the point illuminated by the infrared lamp, thereby improving the convenience of operation and the accuracy of drilling.

[0059] The specific implementation process is as follows:

[0060] In the initial state, the lifting platform 15 is located on the top of the threaded rod 17; the clamping plates 6 are close to each other.

[0061] by Figure 1 For example, at the beginning of an exploration operation, the operator must confirm the designated drilling sampling point and sampling depth. Once the drilling sampling point and sampling depth are confirmed, the controller turns on the infrared lamp and moves the entire device so that the infrared lamp is aligned with the drilling sampling point through the sampling hole. At this time, the controller activates the first motor 16 and the second motor 19. The output shaft of the first motor 16 drives the threaded rod 17 to rotate clockwise, and the output shaft of the second motor 19 drives the sampling barrel 2 and the drill bit 3 to rotate, causing the lifting platform 15 to gradually move the sampling barrel 2 and the drill bit 3 downward.

[0062] During the rotation of the sampling tube 2, the sampling tube 2 will drive the center rod 4, the hinged rod 5 and the clamping plate 6 to rotate synchronously, and the clamping plate 6 will move toward the edge of the sampling tube 2. At this time, the connecting rod 11, the piston rod 10 and the piston plate 9 will move away from the clamping plate 6, and then the auxiliary liquid in the piston cavity will be discharged through the drain hole to lubricate and cool the drill bit 3. In this process, the gas in the air will be adsorbed into the piston cavity by the piston plate 9 through the first one-way valve 12. At the same time, the clamping plates 6 move away from each other to provide a sampling space for the sampling tube 2. After the drill bit 3 contacts the ground at the drilling sampling point, it will drill a hole in the ground. The sample (the core in this embodiment) will gradually enter the sampling tube 2 from the bottom of the sampling tube 2 as the drill bit 3 and the sampling tube 2 move downward.

[0063] After reaching the specified depth, the first motor 16 and the second motor 19 will stop running. At this time, the sampling tube 2 and the drill bit 3 will stop moving downward and rotating, and the spring 7 will push the clamping plate 6 closer to the sample, thereby clamping and fixing the sample; at the same time, the cutter head 8 will squeeze the sample to separate the bottom of the sample from the formation; at the same time, the connecting rod 11, the piston rod 10 and the piston plate 9 will move toward the clamping plate 6, pumping the gas in the piston chamber into the extension groove through the second one-way valve 14, and the support rod 13 will extend out of the extension groove, thereby supporting the bottom of the sample.

[0064] After the sampling is completed, the operator starts the first motor 16 through the controller to drive the threaded rod 17 to rotate counterclockwise, so that the lifting platform 15 drives the sampling tube 2 and the drill bit 3 to move up and return to the ground, completing the drilling sampling work.

[0065] In existing resource exploration techniques, when sampling, operators rely on friction between the sample and the inner wall of the drill pipe to engage the sample and remove it from the formation. However, this rock column extraction method, relying solely on friction against the inner wall of the drill pipe, can easily cause the rock column to fall off, resulting in sampling failure. The clamping plate 6 in this embodiment can stably clamp the sample, significantly reducing the risk of sample loss and improving the sampling success rate.

[0066] During sampling, the clamping plate 6 will use the centrifugal force generated when the sampling cylinder 2 rotates to move closer to the edge of the sampling cylinder 2, avoiding occupying the sampling space of the sampling cylinder 2, so that the sample can enter the sampling cylinder 2 through the bottom of the sampling cylinder 2. When the sampling cylinder 2 stops rotating, the clamping plate 6 will immediately reset, thereby quickly clamping the sample to prevent the sample from falling off; through the design of the clamping plate 6, the sampling and clamping functions can be automatically realized without designing an additional motor, which greatly reduces the preparation cost of the device.

[0067] Example 2:

[0068] As attached Figure 1As shown, different from the above embodiment, a scraper ring 20 is vertically slidably fitted in the sampling tube 2, the top of the scraper ring 20 is hinged with a rotating rod 21, and the top of the hanging rod is fixedly connected with the adjacent clamping plate 6 with bolts.

[0069] The specific implementation process is as follows: when the clamping plate 6 moves toward the edge of the sampling tube 2, the rotating rod 21 will rotate in the direction away from the axis of the sampling tube 2, causing the scraper ring 20 to move downward; when the clamping plate 6 moves toward the axis of the sampling tube 2, the rotating rod 21 will rotate in the direction close to the axis of the sampling tube 2, causing the scraper ring 20 to move upward; when the scraper ring 20 moves up and down, the scraper ring 20 will clean the rock and soil around the extension groove to prevent the rock and soil from clogging the extension groove, causing the support rod 13 to be unable to extend outside the extension groove to support the sample.

[0070] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
