Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, and in particular to a layered sampling drilling device for mining. Background Art

[0002] In the process of mineral resource exploration and development, mining layer sampling drilling equipment plays a vital role. Traditional drilling equipment often cannot ensure the purity and representativeness of samples during sampling, especially in multi-layer ore bodies, where samples from different geological layers are easily mixed, affecting the accuracy of subsequent analysis. This problem is particularly prominent in the process of mineral deposit exploration, ore grade assessment, and resource reserve estimation.

[0003] In actual operation, due to the complexity of geological layers, the rock properties and mineral content of different layers may vary significantly. In order to avoid confusing samples from different layers, traditional sampling methods require fine control of the sampling process. However, traditional drilling equipment often has difficulty in achieving high-precision stratified sampling when sampling, especially in deep exploration. The drilling process may cause upper layer samples to fall or contaminate lower layer samples, thereby affecting the accuracy of the samples. Summary of the invention

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. Effective prevention of sample contamination:

[0026] By keeping the sampling port open in the initial state of the drilling pipe and closing the sampling port before the drilling pipe descends to the sampling area, it is possible to effectively prevent the mineral sample from entering the sampling cavity before the drilling pipe contacts the target mineral layer. This design ensures that the mineral sample will not contaminate the sampling cavity before the drilling pipe reaches the target mineral layer and starts sampling, thus avoiding the mixing of samples, thereby maintaining the purity of the samples and ensuring the accuracy of subsequent analysis.

[0027] 2. Stratification independence of samples:

[0028] During the rotation and descent of the drill pipe, the drill bit penetrates the target ore layer, ensuring the stratified independence of the samples. Each sampling cavity corresponds to a ore layer, and the expanded baffle effectively collects the ore layer samples into the corresponding sampling cavity. This design avoids the mixing of samples from different layers, maintains the stratified independence of the samples, ensures the representativeness and accuracy of the samples, and provides reliable data for ore layer analysis and evaluation.

[0029] 3. Prevent sample mixing:

[0030] When the sampling cavity is filled, the driving component is used to rotate the shaft clockwise again to reset the baffle to close the sampling port. Each sampling cavity is closed separately after sampling to prevent the mixing of samples. The sealing of the sampling port of the drilling pipe and the upward movement of the drilling pipe allow the samples in each sampling cavity to be stored independently, avoiding the mixing of samples and further ensuring the purity and accuracy of the samples.

[0031] 4. Optimize equipment cleaning and maintenance:

[0032] When the drilling pipe rises to the preset position, the connection component automatically cancels the connection between the shaft and the drilling pipe. This mechanism allows the shaft to rotate independently without affecting the drilling pipe after sampling, making it convenient for operators to rotate the shaft to clean the equipment. The drive component rotates the shaft, and the blades on the shaft will help remove residual mineral samples or other impurities in the sampling chamber. In this way, the residue in the sampling chamber can be effectively cleaned to ensure the clean state of the sampling chamber and avoid mixing unnecessary materials in the next sampling. This not only improves the convenience of sampling operations, but also optimizes the cleaning process of the equipment, enhances the long-term performance of the equipment, and ensures the accuracy of the samples.

[0048] 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.

[0049] refer to Figure 1-Figure 9 , a stratified sampling drilling device for mining, comprising:

[0050] Drilling frame 100;

[0051] A drilling pipe 101 is provided in the drilling frame 100;

[0052] A plurality of sampling chambers 102 are provided in the drilling pipe 101, and a connecting chamber 103 is provided on the drilling pipe 101;

[0053] A sampling port 104 is provided on the outer wall of the drilling pipe 101 and communicates with the sampling cavity 102. A baffle 105 is rotatably connected to the sampling port 104.

[0054] A rotating shaft 106 is disposed in the sampling cavity 102. The rotating shaft 106 extends into the sampling cavity 102. A plurality of blades 107 are disposed on the outer wall of the rotating shaft 106. The blades 107 are located in the sampling cavity 102.

[0055] A moving component provided between the drilling frame 100 and the drilling pipe 101, used to move the drilling pipe 101 up and down;

[0056] A driving component provided on the drilling pipe 101, for rotating the rotating shaft 106;

[0057] The connecting component provided between the driving component and the drilling pipe 101 is located in the connecting cavity 103 and is used to connect the rotating shaft 106 and the drilling pipe 101. When the driving component rotates the rotating shaft 106 to a preset angle, the drilling pipe 101 can be rotated through the connecting component.

[0058] A rotating component disposed between the rotating shaft 106 and the baffle 105, used to drive the baffle 105 to rotate to a preset angle when the rotating shaft 106 rotates, so as to open the sampling port 104;

[0059] Wherein, when the moving component is capable of moving the drilling pipe 101 upward to a preset position, the provided connecting component is capable of canceling the connection between the rotating shaft 106 and the drilling pipe 101;

[0060] By setting up the drilling frame 100, the operator can place the drilling frame 100 at the drilling position of the mining area. The sampling port 104 of the drilling pipe 101 is in an open state in the initial state. During the operation, the drilling pipe 101 is moved downward by the moving component so that the drill bit at the bottom of the drilling pipe 101 contacts the drilling area. Then, the driving component rotates the rotating shaft 106. When the rotating shaft 106 rotates to a preset angle, the connecting component drives the drilling pipe 101 to rotate. Before the drilling pipe 101 rotates, the rotating component rotates the baffle 105 in the sampling port 104 through the rotation of the rotating shaft 106. When the baffle 105 rotates to a predetermined angle, the sampling port 104 of the drilling pipe 101 is closed, thereby preventing the mineral sample from entering the sampling chamber 102 before the drilling pipe 101 descends to the sampling area. This process ensures that the mineral sample will not enter the sampling chamber 102 before the drilling pipe 101 descends to the target mineral layer, thereby avoiding sample contamination. The baffle 105 not only closes the sampling port 104, but also prevents the upper layer of mineral samples from mixing in, thus helping to ensure the purity of the lower layer of samples.

[0061] During the rotation and descent of the drilling pipe 101, the drill bit contacts and penetrates the target mineral layer. When the target mineral layer is reached, the moving parts are stopped, and the driving parts are used to rotate the rotating shaft 106 counterclockwise. The rotating shaft 106 rotates in the opposite direction to cause the rotating parts to rotate the baffle 105. One end of the baffle 105 contacts the target mineral layer and opens the sampling port 104. At this time, the rotation of the drilling pipe 101 drives the baffle 105 in the expanded state to collect the mineral layer sample into the sampling cavity 102. Each sampling cavity 102 corresponds to a mineral layer, ensuring the stratified independence of the sample. This operation ensures that the samples in each sampling cavity 102 come from its corresponding mineral layer, maintaining the stratified independence of the sample. This design avoids the mixing of samples from different layers, thereby ensuring the representativeness and accuracy of the sample, which is beneficial to the subsequent mineral layer analysis and evaluation.

[0062] After the sampling chamber 102 is filled, the driving component is used to rotate the rotating shaft 106 clockwise again to reset the baffle 105 to close the sampling port 104. Multiple sampling chambers 102 correspond to ore layers of different depths, and each baffle 105 closes the sampling chamber 102 together to prevent sample mixing. After the sampling port 104 of the drilling pipe 101 is closed, the moving component moves the drilling pipe 101 upward to complete the sample collection. The set connecting component automatically cancels the connection between the rotating shaft 106 and the drilling pipe 101 when the drilling pipe 101 rises to the preset position. The operator can rotate the baffle 105 to open the sampling port 104 and take out the samples in each sampling chamber 102. This process ensures that the samples in each sampling chamber 102 are stored independently, prevents mixing between samples, and ensures the purity of the samples. The operator can accurately take out samples of different depths to provide accurate data support for subsequent analysis.

[0063] After taking out a sufficient amount of sample, in order to further optimize the cleaning and maintenance of the equipment, the operator can use the drive component to rotate the shaft 106. The blades 107 on the shaft 106 help to remove the mineral samples or other impurities that may remain in the sampling chamber 102 when rotating. The rotation of the blades 107 will effectively clean the residues in the sampling chamber 102, ensure the clean state of the sampling chamber 102, and avoid unnecessary materials from being mixed into the next sampling. This mechanism not only improves the convenience of the sampling operation, but also ensures the accuracy of the sample and the long-term performance of the equipment. This design optimizes the cleaning process of the equipment and ensures the clean state of the sampling chamber 102. By effectively removing the residual mineral samples or impurities, the situation of mixing unnecessary materials in the next sampling is avoided. This not only improves the convenience of operation, but also enhances the long-term performance of the equipment and the accuracy of the sample.

[0064] As a further solution of the present invention, the connecting component includes a fixing plate 200 connected to the connecting cavity 103, a slide groove 201 is provided on the fixing plate 200, a connecting plate 202 is provided at the bottom of the fixing plate 200, a limiting rod 203 slidably connected to the slide groove 201 is connected to the top of the connecting plate 202, and the rotating shaft 106 is connected to the connecting plate 202;

[0065] By providing the connecting plate 202, when in use, the connecting plate 202 can be rotated by the driving component, and the limiting rod 203 on the connecting plate 202 follows the rotation, and the limiting rod 203 can slide freely in the sliding groove 201 by sliding cooperation with the sliding groove 201. When the limiting rod 203 slides to the extreme position of the sliding groove 201, the connecting plate 202 continues to rotate, and the rotation of the connecting plate 202 will drive the fixed plate 200 to rotate synchronously through the cooperation between the limiting rod 203 and the sliding groove 201. In this way, the purpose of driving the drilling pipe 101 connected to the fixed plate 200 to rotate when the rotating shaft 106 is rotated to a preset angle can be achieved. When it is necessary to cancel the transmission between the rotating shaft 106 and the drilling pipe 101 in the future, the connecting plate 202 can be moved downward to allow the limit rod 203 to disengage from the slide groove 201. This mechanism ensures that the rotating shaft 106 can rotate alone while the drilling pipe 101 remains stationary, thereby achieving the safe release of the connection between the rotating shaft 106 and the drilling pipe 101. In addition, each time the rotating shaft 106 rotates forward and then reversely, the mechanism of rotating the rotating shaft 106 first rotating and then rotating the drilling pipe 101 can be achieved, thereby ensuring precise control of the drilling pipe 101 during operation and optimizing the equipment stability and efficiency during the sampling process.

[0066] As a further solution of the present invention, the rotating component includes a partition 300 connected to the sampling chamber 102, a closed chamber 301 is formed between the partition 300 and the sampling chamber 102, a connecting groove 302 is formed on the side wall of the closed chamber 301, a connecting shaft 303 is connected to the baffle 105, the connecting shaft 303 extends into the connecting groove 302 and is connected to a first gear 304, and a second gear 305 meshing with the first gear 304 is provided on the rotating shaft 106;

[0067] By providing the partition 300 , the partition 300 forms a closed cavity 301 . The design of the closed cavity 301 ensures that the ore sample and other impurities will not enter the gear system. In this way, wear or jamming caused by dust or debris of the ore sample entering the gear system can be avoided, thereby extending the service life of the gear system. When the shaft 106 rotates, it can drive the second gear 305 to rotate. The second gear 305 can rotate the connecting shaft 303 through the transmission of the first gear 304. The rotation of the baffle 105 is driven by the movement of the shaft 106 to achieve the purpose of rotating the baffle 105. After the baffle 105 rotates to the extreme angle to open or close the sampling port 104, the limit rod 203 slides to the extreme position in the slide groove 201. This design ensures that the movement range of the baffle 105 is effectively limited, so that the baffle 105 will not exceed the design range during the opening and closing process, ensuring the stable operation and accurate position of the sampling port 104. In addition, when the drilling pipe 101 drills the drilling area to form a hole, if the baffle 105 rotates to open the sampling port 104 The rotation angle of the baffle 105 will be limited by the size of the hole diameter. For this reason, a gear system is added to open the design of the baffle 105. Even if the baffle 105 cannot be fully unfolded due to space limitations, when the rotation angle of the baffle 105 is limited, the shaft 106 can also use the inability of the gear system to rotate to transmit to the drilling pipe 101, thereby avoiding affecting the normal operation of the drilling pipe 101 due to the limited rotation of the baffle 105. Furthermore, when the baffle 105 is not fully unfolded, following the rotation of the drilling pipe 101, the baffle 105 will scrape the inner wall of the drilled hole, thereby ensuring effective collection of samples. This design not only solves the problem of the baffle 105 being limited in unfolding due to the hole diameter, but also ensures that in a complex drilling environment, the sample can be accurately collected into the corresponding sampling cavity 102, thereby further optimizing the sample collection process.

[0068] As a further solution of the present invention, a first limiting groove 306 is provided on the rotating shaft 106, the second gear 305 is slidably connected in the first limiting groove 306, and an avoidance groove 307 communicating with the first limiting groove 306 is provided on the rotating shaft 106;

[0069] By providing the first limiting groove 306, the second gear 305 can be rotated by using the first limiting groove 306 when the rotating shaft 106 rotates. When the connecting plate 202 is moved downward to allow the limiting rod 203 to disengage from the slide groove 201, the rotating shaft 106 moves downward synchronously. At this time, the second gear 305 slides in the first limiting groove 306 and enters the avoidance groove 307. The design of the avoidance groove 307 ensures that the position of the second gear 305 can be effectively avoided, thereby avoiding the movement interference between the rotating shaft 106 and the second gear 305 when rotating. This mechanism is particularly suitable for preventing movement interference when cleaning the residual sample in the sampling chamber 102 through the blade 107, thereby ensuring the smooth operation of the device and the smooth progress of the cleaning process.

[0070] As a further solution of the present invention, the connecting component also includes a bracket 400 connected to the drilling frame 100, a top rod 401 is connected to the bottom of the bracket 400, a connecting ring 402 is provided on the top of the drilling pipe 101, a connecting rod 403 extending into the drilling pipe 101 is connected to the bottom of the connecting ring 402, the connecting rod 403 passes through the fixing plate 200 and is slidably connected to the connecting plate 202, and a first spring 404 is connected between the connecting rod 403 and the fixing plate 200;

[0071] By setting the bracket 400, the bracket 400 can support the position of the push rod 401, and the first spring 404 can support the position of the connecting plate 202, so that the connecting plate 202 can be firmly connected with the slide groove 201 in the initial state and maintain the stability of its position during the entire operation process. After the sampling of the drilling pipe 101 is completed, when the drilling pipe 101 is reset and moved upward to the position of the push rod 401, the push rod 401 can touch the connecting ring 402 and allow the connecting rod 403 to slide relative to the drilling pipe 101. Since the connecting rod 403 is connected to the connecting plate 202, the connecting plate 202 can be connected to the connecting plate 202. The connecting plate 202 can move relative to the fixed plate 200, allowing the limiting rod 203 to leave the slide groove 201, thereby releasing the connection between the rotating shaft 106 and the drilling pipe 101. This design ensures that after the sampling of the drilling pipe 101 is completed, the position of the connecting rod 403 can be adjusted so that the limiting rod 203 can be disengaged from the slide groove 201 when needed, so that the rotating shaft 106 can be freely rotated in subsequent operations to perform other operations, such as cleaning residual samples in the sampling chamber 102, avoiding transmission interference between the rotating shaft 106 and the drilling pipe 101, thereby improving the operational flexibility and use efficiency of the equipment.

[0072] As a further solution of the present invention, a second limiting groove 405 is provided on the rotating shaft 106, a ring body 406 is slidably connected to the second limiting groove 405, a protective tube 407 is rotatably connected to the ring body 406, the blade 107 is connected to the protective tube 407, and a ratchet mechanism 408 is connected between the ring body 406 and the protective tube 407;

[0073] By setting the second limiting groove 405, the cooperation between the second limiting groove 405 and the ring body 406 can make the ring body 406 rotate when the rotating shaft 106 rotates. The setting of the second limiting groove 405 can ensure the transmission of the rotating shaft 106 and the ring body 406 after the rotating shaft 106 moves downward. In addition, when the rotating shaft 106 rotates clockwise to rotate the baffle 105 to open the sampling port 104, the ring body 406 can rotate the protective tube 407 through the ratchet mechanism 408 to rotate the blade 107. This process is carried out when there is no sample in the sampling chamber 102, avoiding interference or mixing of the sample. After the subsequent samples enter the sampling chamber 102, the one-way transmission characteristics of the ratchet mechanism 408 will be utilized to prevent the rotation of the blade 107 from affecting the samples when the baffle 105 is reset and rotated to close the sampling port 104. Furthermore, when the drilling pipe 101 moves upward to the preset position and the rotating shaft 106 moves downward and no longer transmits the second gear 305 and the first gear 304, the operator can manually open it after the preparation work for removing the samples is completed to facilitate the removal of the samples. The setting of the ratchet mechanism 408 effectively avoids potential problems caused by the rotation of the blade 107.

[0074] As a further solution of the present invention, the driving component includes a connecting frame 500 provided on the drilling frame 100, the connecting frame 500 is connected to a first motor 501, the driving shaft of the first motor 501 extends into the drilling pipe 101, the connecting frame 500 is connected to a plurality of support rods 502 slidably connected to the drilling pipe 101, the bottom of the driving shaft of the first motor 501 is connected to a first rod 503, the bottom of the first rod 503 is slidably connected to a second rod 504 connected to the connecting plate 202, and a second spring 505 is connected between the first rod 503 and the second rod 504;

[0075] By setting a support rod 502, the support rod 502 can support the position of the drilling pipe 101, and the setting of the connecting frame 500 can support the position of the first motor 501, thereby ensuring stability during the drilling process. The setting of the first rod 503, the second rod 504 and the second spring 505 ensures that the connecting plate 202 maintains the connection with the driving shaft of the first motor 501 while being able to slide, thereby avoiding the position change of the connecting plate 202 affecting the driving effect, and improving the reliability of the drilling operation.

[0076] As a further solution of the present invention, the moving part includes a screw rod 506 connected to the drilling frame 100, the bottom of the drilling frame 100 is connected to a base 507, the base 507 is connected to a second motor 508, the drive shaft of the second motor 508 is connected to the screw rod 506, and the connecting frame 500 is connected to the screw rod 506;

[0077] By setting the second motor 508, when the second motor 508 is running, the screw rod 506 can be rotated to linearly move the position of the connecting frame 500, so as to achieve the purpose of moving the motor and the drilling pipe 101 downward to perform drilling work. The second motor 508 drives the screw rod 506 to adjust the position of the drilling pipe 101, which reduces the need for manual operation, improves work efficiency and automation, and the use of the screw rod 506 enables the drilling pipe 101 to adapt to different drilling depth requirements. By adjusting the operation of the motor, the up and down movement of the drilling pipe 101 can be flexibly controlled to meet the drilling requirements of different depths. The operating accuracy and stability of the drilling equipment are enhanced, while the automation level of the operation and the durability of the equipment are improved.

[0078] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
