Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, and in particular, to a mineral geological exploration sampling device capable of multi-point sampling simultaneously. Background Art

[0002] Minerals generally refer to all natural minerals or rock resources buried underground (or distributed on the surface, or weathered from rocks, or deposited from rocks) that can be utilized by humans. Minerals can be classified into categories such as metals, non-metals, and combustible organics, and are non-renewable resources. Before mining the minerals buried underground, special sampling devices are required to sample the soil in the strata to determine the mineral content.

[0003] During the sampling process of existing sampling devices at mineral sites, since the ore is buried underground, it is easy to be blocked by larger ores during the process of single sampling, resulting in the sampling device being unable to accurately obtain samples. Therefore, we provide a mineral geological exploration sampling device capable of multi-point sampling simultaneously to solve the above problems. Summary of the Invention

[0012] As a further solution of the present invention: The blocking block is set in a bent shape. The ball is initially in contact with the inclined surface at the bottom end of the blocking block. There are multiple blocking blocks, and the multiple blocking blocks are equidistantly distributed inside the auxiliary sliding groove.

[0013] The present invention also discloses a mineral geological exploration sampling method capable of simultaneously sampling at multiple points. Using the above-mentioned mineral geological exploration sampling device capable of simultaneously sampling at multiple points, it includes the following steps:

[0014] S1. First, when the support frame needs to be moved to a specified position for sampling, start the first driving motor and the second driving motor. The output end of the first driving motor drives the first one-way threaded lead screw to rotate, thereby driving the sliding seat to drive the auger rod to move downward. The output end of the second driving motor drives the auger rod to rotate, so that the auger rod drills into the soil;

[0015] S2. The diameter of the feed inlet of the circular sampling bucket is larger than that of the drill bit. After the circular sampling bucket is installed inside the auger rod, the power motor can be started. The output end of the power motor drives the second one-way threaded lead screw to rotate, thereby driving the circular sampling bucket to move into the through hole, so as to block the through hole. The drill bit and the sealing rubber cooperate to block the feed inlet of the circular sampling bucket. When the auger rod drills down to the maximum position, start the power motor and the sampling motor. The output end of the power motor drives the second one-way threaded lead screw to rotate, thereby driving the slider to drive the circular sampling bucket out of the auger rod through the sliding sleeve to the outside. During this process, the output end of the sampling motor drives the circular sampling bucket to rotate. With the cooperation of the drill bit, the circular sampling bucket is removed from the soil around the auger rod. When the circular sampling bucket completely moves out of the auger rod, start the traction motor. The output end of the traction motor drives the first rotating shaft to drive the connecting rod to rotate, so that the baffle and the drill bit can swing into the circular sampling bucket, so as to facilitate the circular sampling bucket to take materials during the subsequent lateral movement. The feed inlet of the circular sampling bucket is blocked by the baffle and the drill bit, so as to prevent the samples outside the sampling position from entering the circular sampling bucket during the drilling process of the auger rod, thereby improving the sampling accuracy of the sampling product;

[0016] S3. When the circular sampling bucket moves laterally and contacts the soil layer, when the circular sampling bucket initially contacts a large ore in the soil layer, the circular sampling bucket is resisted during the movement. Then the sliding sleeve pushes the circular sampling bucket to continue moving through the contraction sleeve, so that the contraction sleeve squeezes the strong spring to slide relative to the sliding sleeve. When the rectangular power rod contacts the sliding sleeve, the sliding sleeve pushes the rectangular power rod to drive the first rack to move laterally. The second rack drives the spur gear to drive the second rotating shaft to rotate in the reverse direction. When the teeth on the outer wall of the second rack are separated from the spur gear, the teeth on the outer wall of the first rack contact the spur gear and drive the spur gear to rotate forward, thereby realizing the function of the circular sampling bucket to swing reciprocally, so as to adjust the sampling position of the circular sampling bucket, thereby reducing the interference received by the circular sampling bucket during sampling, so as to facilitate the circular sampling bucket to sample stably;

[0017] S4. When the shrink sleeve slides relative to the inner side of the sliding sleeve, it slides inside the auxiliary chute through the rectangular auxiliary block. Under the action of the inclined surface at the inner bottom end of the blocking block, the rolling ball is pushed to drive the limiting block to squeeze the compression spring and move downward. When the rolling ball separates from the bottom inclined surface of the blocking block, the compression spring pushes the limiting block to drive the rolling ball to reset, so that the limiting ring can be stuck between the two blocking blocks, thereby being able to limit the shrink sleeve, making the circular sampling bucket after adjusting the position not reset, and thus improving the stability of the circular sampling bucket after adjusting the position.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By setting the position conversion regulator, the function that the circular sampling bucket can swing reciprocally when initially contacting the larger ore in the soil layer through the position conversion regulator, thereby adjusting the sampling position of the circular sampling bucket, reducing the interference received by the circular sampling bucket during the sampling process, and thus facilitating the circular sampling bucket to sample stably;

[0020] 2. By setting the blocking and protecting member, when the circular sampling bucket completely moves out of the inside of the spiral drill rod, the baffle and the drill bit swing into the inside of the circular sampling bucket, so as to facilitate the circular sampling bucket to take materials during the process of continuing to move horizontally. The baffle and the drill bit block the feeding port of the circular sampling bucket, thereby preventing samples that do not belong to the sampling position from entering the inside of the circular sampling bucket during the drilling process of the spiral drill rod, and thus improving the sampling accuracy of the sampling product;

[0021] 3. By setting the limiting and assisting mechanism, the limiting ring can be stuck between the two blocking blocks through the limiting and assisting mechanism, thereby being able to limit the shrink sleeve, making the circular sampling bucket after adjusting the position not reset, and thus improving the stability of the circular sampling bucket after adjusting the position.

Limiting auxiliary mechanisms for limiting the contraction sleeve 38 are arranged on both sides of the contraction sleeve 38; a blocking and protecting member for blocking the feeding port of the circular sampling bucket 10 is arranged at the feeding port of the circular sampling bucket 10.

[0038] In this embodiment: First, when the support frame 1 is moved to a specified position for sampling, the first driving motor 3 and the second driving motor 6 are started first. The output end of the first driving motor 3 drives the first one-way threaded lead screw 4 to rotate, thereby driving the sliding seat 5 to drive the spiral drill rod 7 to move downward. The output end of the second driving motor 6 drives the spiral drill rod 7 to rotate, so that the spiral drill rod 7 drills into the soil.

[0039] Please refer specifically to Figures 5 to 9 , a power motor 18 is installed at the top of the fixed seat 9. The output end of the power motor 18 is connected to a second one-way threaded lead screw 17. The slider 16 is sleeved on the outer wall of the second one-way threaded lead screw 17. A limiting chute matching the slider 16 is opened at the top of the fixed seat 9. A threaded groove matching the second one-way threaded lead screw 17 is provided inside the slider 16. The blocking and protecting member includes a support 23 fixedly connected inside the circular sampling bucket 10. A connecting rod 24 is arranged inside the support 23.

[0040] In this embodiment: The diameter of the feeding port of the circular sampling bucket 10 is larger than that of the drill bit 22. After the circular sampling bucket 10 is installed inside the auger 7, the power motor 18 can be started. The output end of the power motor 18 drives the second one-way threaded lead screw 17 to rotate, thereby driving the circular sampling bucket 10 to move into the through hole 15, so as to block the through hole 15. The drill bit 22 and the sealing rubber 29 cooperate to block the feeding port of the circular sampling bucket 10. When the auger 7 drills down to the maximum position, the power motor 18 and the sampling motor 20 are started. The output end of the power motor 18 drives the second one-way threaded lead screw 17 to rotate, thereby driving the slider 16 to drive the circular sampling bucket 10 to move out of the auger 7 to the outside through the sliding sleeve 11. During this process, the output end of the sampling motor 20 drives the circular sampling bucket 10 to rotate. With the cooperation of the drill bit 22, the circular sampling bucket 10 is removed from the soil around the auger 7. When the circular sampling bucket 10 completely moves out of the auger 7, the traction motor 30 is started. The output end of the traction motor 30 drives the first rotating shaft 31 to drive the connecting rod 24 to rotate, so that the baffle 21 and the drill bit 22 can swing into the circular sampling bucket 10, so as to facilitate the circular sampling bucket 10 to take materials during the subsequent lateral movement. The feeding port of the circular sampling bucket 10 is blocked by the baffle 21 and the drill bit 22, so as to prevent samples outside the sampling position from entering the circular sampling bucket 10 during the drilling process of the auger 7, thereby improving the sampling accuracy of the sampled products.

A guiding groove matching the rectangular power rod 26 is opened inside the retractable sleeve 38. One end of the rectangular power rod 26 is initially far from one end inside the sliding sleeve 11.

[0042] In this embodiment: When the circular sampling bucket 10 moves horizontally and contacts the soil layer, when the circular sampling bucket 10 initially contacts a larger ore in the soil layer, the circular sampling bucket 10 encounters resistance during the movement, and then the sliding sleeve 11 pushes the circular sampling bucket 10 to continue moving through the retractable sleeve 38, so that the retractable sleeve 38 squeezes the strong spring 25 to slide relative to the sliding sleeve 11. When the rectangular power rod 26 contacts the sliding sleeve 11, under the action of the sliding sleeve 11, the rectangular power rod 26 is pushed to drive the first rack 28 to move horizontally. The second shaft 32 is driven to rotate reversely by driving the spur gear 33 through the second rack 34. When the teeth on the outer wall of the second rack 34 are separated from the spur gear 33, the teeth on the outer wall of the first rack 28 contact the spur gear 33, driving the spur gear 33 to rotate forward. In this way, the function of the circular sampling bucket 10 to swing reciprocally is realized, so as to adjust the sampling position of the circular sampling bucket 10, thereby reducing the interference received by the circular sampling bucket 10 during the sampling process, and facilitating the circular sampling bucket 10 to sample stably.

A blocking block 36 is fixedly connected to the inner side of the auxiliary chute 46. A compression spring 41 is fixedly connected to the bottom end of the limiting block 42. The bottom end of the compression spring 41 is fixedly connected to the retractable block 40. A micro electric push rod 37 is installed in the inner side of the retractable sleeve 38.

There are multiple blocking blocks 36, and the multiple blocking blocks 36 are equidistantly distributed in the inner side of the auxiliary chute 46.

[0044] In this embodiment: When the retractable sleeve 38 slides relative to the inner side of the sliding sleeve 11, the rectangular auxiliary block 39 slides in the inner side of the auxiliary chute 46. Under the action of the inclined surface at the bottom end inside the blocking block 36, the ball 44 is pushed to drive the limiting block 42 to squeeze the compression spring 41 to move downward. When the ball 44 is separated from the bottom inclined surface of the blocking block 36, the compression spring 41 pushes the limiting block 42 to drive the ball 44 to reset, so that the limiting ring 43 can be stuck between the two blocking blocks 36, thereby being able to limit the retractable sleeve 38, so that the circular sampling bucket 10 after adjusting the position will not reset, thus improving the stability of the circular sampling bucket 10 after adjusting the position.

[0045] The following provides a mineral geological exploration sampling method capable of simultaneously sampling at multiple points in combination with the above-mentioned mineral geological exploration sampling device capable of simultaneously sampling at multiple points, which specifically includes the following steps:

[0046] S1. First, when the support frame 1 is moved to the designated position for sampling, start the first drive motor 3 and the second drive motor 6 first. The output end of the first drive motor 3 drives the first one-way threaded lead screw 4 to rotate, thereby driving the sliding seat 5 to drive the screw drill rod 7 to move downward. The output end of the second drive motor 6 drives the screw drill rod 7 to rotate, so that the screw drill rod 7 drills into the soil.

[0047] S2. The diameter of the feed inlet of the circular sampling bucket 10 is larger than that of the drill bit 22. After the circular sampling bucket 10 is installed inside the screw drill rod 7, the power motor 18 can be started. The output end of the power motor 18 drives the second one-way threaded lead screw 17 to rotate, thereby driving the circular sampling bucket 10 to move into the through hole 15, so as to block the through hole 15. The drill bit 22 and the sealing rubber 29 cooperate to block the feed inlet of the circular sampling bucket 10. When the screw drill rod 7 drills down to the maximum position, start the power motor 18 and the sampling motor 20. The output end of the power motor 18 drives the second one-way threaded lead screw 17 to rotate, thereby driving the slider 16 to drive the circular sampling bucket 10 to move out of the screw drill rod 7 to the outside through the sliding sleeve 11. During this process, the output end of the sampling motor 20 drives the circular sampling bucket 10 to rotate. With the cooperation of the drill bit 22, the circular sampling bucket 10 is removed from the soil around the screw drill rod 7. When the circular sampling bucket 10 completely moves out of the screw drill rod 7, start the traction motor 30. The output end of the traction motor 30 drives the first rotating shaft 31 to drive the connecting rod 24 to rotate, so that the baffle 21 and the drill bit 22 can swing into the circular sampling bucket 10, so that the circular sampling bucket 10 can take materials during the subsequent lateral movement. The feed inlet of the circular sampling bucket 10 is blocked by the baffle 21 and the drill bit 22.

[0048] S3. When the circular sampling bucket 10 moves horizontally and contacts the soil layer, when the circular sampling bucket 10 initially contacts a larger ore in the soil layer, the circular sampling bucket 10 encounters resistance during the movement. Then, the sliding sleeve 11 pushes the circular sampling bucket 10 to continue moving through the contraction sleeve 38, so that the contraction sleeve 38 squeezes the strong spring 25 and slides relative to the sliding sleeve 11. When the rectangular power rod 26 contacts the sliding sleeve 11, under the action of the sliding sleeve 11, the rectangular power rod 26 is pushed to drive the first rack 28 to move horizontally. The second rack 34 drives the spur gear 33 to drive the second rotating shaft 32 to rotate in the reverse direction. When the teeth on the outer wall of the second rack 34 are separated from the spur gear 33, the teeth on the outer wall of the first rack 28 contact the spur gear 33 and drive the spur gear 33 to rotate in the forward direction, thereby realizing the function of the circular sampling bucket 10 swinging reciprocally, so as to adjust the sampling position of the circular sampling bucket 10;

[0049] S4. When the contraction sleeve 38 slides relative to the inner side of the sliding sleeve 11, the rectangular auxiliary block 39 slides inside the auxiliary chute 46. Under the action of the inclined surface at the inner bottom end of the blocking block 36, the rolling ball 44 is pushed to drive the limiting block 42 to squeeze the compression spring 41 and move downward. When the rolling ball 44 is separated from the bottom inclined surface of the blocking block 36, the compression spring 41 pushes the limiting block 42 to drive the rolling ball 44 to reset, so that the limiting ring 43 can be stuck between the two blocking blocks 36, thereby being able to limit the contraction sleeve 38.

9. A method for using a mineral geological exploration sampling device capable of simultaneously sampling at multiple points as described in any one of claims 1-8, characterized in that, It includes the following steps: S1. First, when the support frame (1) is moved to a specified position for sampling, start the first driving motor (3) and the second driving motor (6) first. The output end of the first driving motor (3) drives the first one-way threaded lead screw (4) to rotate, thereby driving the sliding seat (5) to drive the spiral drill rod (7) to move downward. The output end of the second driving motor (6) drives the spiral drill rod (7) to rotate, so that the spiral drill rod (7) drills into the soil. S2. The diameter of the feeding port of the circular sampling bucket (10) is larger than that of the drill bit (22). After the circular sampling bucket (10) is installed inside the auger stem (7), the power motor (18) can be started. The output end of the power motor (18) drives the second one-way threaded lead screw (17) to rotate, thereby driving the circular sampling bucket (10) to move into the through hole (15) to block the through hole (15). The drill bit (22) cooperates with the sealing rubber (29) to block the feeding port of the circular sampling bucket (10). When the auger stem (7) drills down to the maximum position, the power motor (18) and the sampling motor (20) are started. The output end of the power motor (18) drives the second one-way threaded lead screw (17) to rotate, thereby driving the slider (16) to drive the circular sampling bucket (10) out of the auger stem (7) through the sliding sleeve (11). During this process, the output end of the sampling motor (20) drives the circular sampling bucket (10) to rotate. With the cooperation of the drill bit (22), the circular sampling bucket (10) is removed from the soil around the auger stem (7). When the circular sampling bucket (10) completely moves out of the auger stem (7), the traction motor (30) is started. The output end of the traction motor (30) drives the first rotating shaft (31) to drive the connecting rod (24) to rotate, so that the baffle (21) and the drill bit (22) can swing into the circular sampling bucket (10) to facilitate the circular sampling bucket (10) to take materials during the subsequent lateral movement. The feeding port of the circular sampling bucket (10) is blocked by the baffle (21) and the drill bit (22); S3. When the circular sampling bucket (10) moves laterally and contacts the soil layer, when the circular sampling bucket (10) initially contacts a large ore in the soil layer, the circular sampling bucket (10) encounters resistance during movement. Then the sliding sleeve (11) pushes the circular sampling bucket (10) to continue moving through the retractable sleeve (38), so that the retractable sleeve (38) squeezes the strong spring (25) and slides relative to the sliding sleeve (11). When the rectangular power rod (26) contacts the sliding sleeve (11), under the action of the sliding sleeve (11), the rectangular power rod (26) is pushed to drive the first rack (28) to move laterally. The second rack (34) drives the spur gear (33) to drive the second rotating shaft (32) to rotate in the reverse direction. When the teeth on the outer wall of the second rack (34) are separated from the spur gear (33), the teeth on the outer wall of the first rack (28) contact the spur gear (33) and drive the spur gear (33) to rotate in the forward direction, thus realizing the function of the circular sampling bucket (10) to swing reciprocally; S4. When the shrink sleeve (38) slides relative to the inside of the sliding sleeve (11), it slides inside the auxiliary chute (46) through the rectangular auxiliary block (39). Under the action of the inclined surface at the inner bottom end of the blocking block (36), the ball (44) is pushed to drive the limiting block (42) to squeeze the compression spring (41) and move downward. When the ball (44) separates from the bottom inclined surface of the blocking block (36), the compression spring (41) pushes the limiting block (42) to drive the ball (44) to reset, so that the limiting ring (43) can be stuck between the two blocking blocks (36), thereby being able to limit the shrink sleeve (38).
