Specific implementation mode

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] Embodiment:

[0027] As Figures 1-5 shown, the present invention provides a mineral exploration sampling device, including a drill pipe and a sampling mechanism arranged inside the drill pipe. The sampling mechanism includes a pushing head 1 and a plurality of sampling spoons 2. The pushing head 1 is frustum-shaped, and one end thereof is provided with a cylinder 18. The cylinder 18 can be used to drive its lifting. In addition to the cylinder 18, a motor component can also be provided. The cylinder 18 is selected in this embodiment. The drill pipe is tubular. In order to control the action of the cylinder 18, an air pipe is also passed through the inside of the drill pipe. The air pipe gradually extends downward along with the drill pipe, and one end thereof is exposed to the ground, facilitating the ground personnel to perform ventilation control.

[0028] A plurality of through holes are provided on the side wall of the drill pipe. Each of the plurality of sampling spoons 2 is slidably arranged inside a through hole, so that the sampling spoon 2 can extend out of the outer wall of the drill pipe or retract into the drill pipe. As Figure 1 and 2As shown, when the sampling spoon 2 retracts, its outer surface is flush with the outer surface of the drill pipe, thereby closing the through-hole of the drill pipe and preventing impurities from entering the interior of the drill pipe through the through-hole during rotation. The pushing head 1 is arranged in cooperation with a plurality of sampling spoons 2. Specifically, the sampling spoon 2 is arranged in cooperation with the pushing head 1 in an inclined shape, so that the telescoping of the pushing head 1 can drive a plurality of sampling spoons 2 to extend or retract. In order to drive the sampling spoon 2 to retract, the sampling spoon 2 and the pushing head 1 are respectively provided with a dovetail groove and a dovetail slider. The sampling spoon 2 and the pushing head 1 are slidably connected together, so that the actions of the sampling spoon 2 and the pushing head 1 are consistent. At the same time, in order to ensure the stable telescoping of the sampling spoon 2 relative to the through-hole, the contact position between the sampling spoon 2 and the through-hole is also provided with a dovetail groove and a dovetail slider. A drill bit 3 is provided at the front end of the drill pipe.

[0029] When the mineral exploration sampling device of the present invention is in use, the drill pipe drives the drill bit 3 to rotate, causing the drill bit 3 to gradually drill downward. When the sampling spoon 2 follows the drilling to the sampling depth, by introducing air into the cylinder 18, the pushing head 1 is used to push a plurality of sampling spoons 2 to extend out of the drill pipe through the through-hole of the drill pipe, so that the sampling spoons 2 contact the hole wall during rotation, and then samples such as ore or soil in the formation are collected into the sampling spoons 2. After sampling, air is introduced into the cylinder 18 in the reverse direction, causing the pushing head 1 to retract and bringing the sampling spoon 2 back into the drill pipe. The drill pipe can be taken out to take out the samples retained in the sampling spoon 2. This enables drilling and sampling to be carried out synchronously, avoiding the trouble caused by lifting the drill pipe to replace the sampling device.

[0030] In this embodiment, a sample box 4 is further included. The sample box 4 is arranged inside the drill pipe and between the sampling mechanism and the drill bit 3. That is to say, the sample box 4 is located below the sampling mechanism, so that the sampled samples fall into the sample box 4, thereby better storing the samples. The size of the sample box 4 is smaller than the inner diameter of the drill pipe, so that the sample box 4 can be placed inside the drill pipe. This also enables the sample box 4 to be easily taken out, thereby facilitating the taking out of the samples inside the sample box 4.

[0031] In this embodiment, a plurality of partition plates are arranged in the sample box 4 from top to bottom, so that the interior of the sample box 4 is divided into a plurality of chambers by the plurality of partition plates. As Figure 5 shown, the partition plate includes a fixed part 5 and a flipping part 6 hinged to the fixed part 5. A plurality of flipping parts 6 are arranged on the same straight line, so that when all the flipping parts 6 are turned up, the samples can fall from the top of the sample box 4 to the bottom. A diversion groove 7 is also arranged inside the drill pipe. The diversion groove 7 is in a funnel shape and is arranged in cooperation with the sampling spoon 2 and the sample box 4. Specifically, the diversion groove 7 is arranged below the sampling spoon 2 and above the sample box 4, so that the samples in the sampling spoon 2 flow into the sample box 4 through the diversion groove 7. The outlet of the diversion groove 7 is located directly above the flipping part 6. The flipping part 6 is also provided with a driving mechanism for driving its flipping.

[0032] During sampling, the sampling spoon 2 rotates for sampling. The obtained sample enters the diversion groove 7 and finally flows into the interior of the sample box 4. Initially, all the flipping parts 6 are turned up, and the sample first drops to the bottom of the sample box 4. After the first sampling is completed, the lowermost flipping part 6 is driven by the driving mechanism to flip to the horizontal position, so that the lowermost chamber of the sample box 4 is sealed. When sampling next time, the same method is used for sampling, and at this time the sample will drop onto the flipped flipping part 6 and the corresponding fixing part 5. That is to say, the two adjacent upper and lower chambers are separated from each other, so that the samples of each sampling are isolated from each other.

[0033] In this embodiment, the driving mechanism includes a driving rod 8, a winding wheel 9 and a pulling rope 10. As Figure 4 shown, the pulling rope 10 is connected to the winding wheel 9 and the flipping part 6, so that when the winding wheel 9 winds the pulling rope 10, the flipping part 6 flips from the turned-up state to the flat state. A set of winding wheel 9 and pulling rope 10 is correspondingly arranged for each flipping part 6. Thus, each flipping part 6 can be controlled separately. A transmission tooth is arranged on the rotating shaft of the winding wheel 9. A set of driving teeth 11 is arranged on the driving rod 8 in cooperation with the transmission teeth of each winding wheel 9. When the driving rod 8 moves, it will drive the winding wheel 9 to rotate, and then wind and release the pulling rope 10. The distances between adjacent two sets of driving teeth 11 are relatively arranged, so that when the driving rod 8 advances a driving distance, several winding wheels 9 from bottom to top sequentially wind a corresponding section of their pulling ropes 10. Specifically, let the distribution length of a set of driving teeth 11 on the driving rod 8 be a pushing length. In the initial state, the lowermost driving tooth 11 just meshes with the lowermost winding wheel 9. After the driving rod 8 is pushed downward by a pushing length, the lowermost driving tooth 11 just completely passes through the lowermost winding wheel 9. At this time, a set of driving teeth 11 adjacent to the lowermost driving tooth 11 just meshes with the winding wheel 9 adjacent to the lowermost winding wheel 9. And going up in turn, the distance between the upper driving tooth 11 and the upper winding wheel 9 is just a pushing length. The distance between the next set of driving teeth 11 and the winding wheel 9 is two pushing lengths. That is to say, each time the driving rod 8 is pressed once and the pressing length is a pushing length, several flipping parts 6 will flip from bottom to top to the horizontal position in turn.

[0034] Based on this, after each sampling is completed, pressing the driving rod 8 once can make the corresponding flipping part 6 flip once, so as to seal the just sampled sample in the lower chamber. And the rotation of a set of driving teeth 11 driving the corresponding winding wheel 9 can just drive the flipping part 6 to flip to an acute angle with the horizontal plane, so that it can drop to the horizontal under the action of gravity. In order to better ensure that the flipping part 6 will not flip out of control to the horizontal during use, the state when the flipping part 6 is turned up is as Figure 4As shown, the angle of its turning up is an obtuse angle, so that it will not turn back without reason under the action of gravity after turning up. In addition, when setting the spacing between adjacent partitions, it should be ensured that each group of driving teeth 11 can only cooperate with one winding wheel 9 during the process of the driving rod 8 turning all the turning parts 6 back.

[0035] In this embodiment, a driving part is also included, which is used to press the driving rod 8. Figure 3 As shown, the driving part includes a transmission rod 12, a ratchet 13 and a power component. Ratchets are arranged on both sides of the transmission rod 12 and ratchets 14 and ratchet 13 are arranged on both sides respectively, so that the ratchet 14 prevents the transmission rod 12 from moving up, and the ratchet 13 drives the transmission rod 12 downward when rotating forward and slides relative to the transmission rod 12 when rotating reversely. Figure 3 For example, the ratchet 13 rotates counterclockwise in the forward direction, and the ratchet 13 rotates clockwise in the reverse direction. The power component is connected to the ratchet 13 so that the power component drives the ratchet 13 to rotate. The transmission rod 12 is arranged above the driving rod 8 so that the driving rod 8 can be pushed down by lowering the transmission rod 12.

[0036] Specifically, the power component includes a cylinder 15, a piston 16 and a return spring 17. The piston 16 is disposed inside the cylinder 15. The lower portion of the cylinder 15 is connected to the edge of the ratchet 13 through a connecting rod 23, so that the piston 16 moves downward to push the ratchet 13 to rotate in the positive direction. The return spring 17 is connected to the piston 16, so that after the pressure inside the cylinder 15 is released, the return spring 17 drives the piston 16 to return to its original position.

[0037] When gas is introduced into the cylinder 15, the piston 16 moves downward, the ratchet 13 rotates forward, and then pushes the transmission rod 12 downward, so that the transmission rod 12 presses the driving rod 8 downward. When the piston 16 moves to the bottom, the distance that the ratchet 13 drives the transmission rod 12 to descend is just a pushing length. When the pressure inside the cylinder 15 is released, the reset spring 17 drives the piston 16 to reset, and at the same time, the ratchet 13 rotates in the reverse direction. When the ratchet 13 rotates in the reverse direction, the pawl 14 prevents the transmission rod 12 from moving upward. Because its ratchet teeth cooperate with the ratchet teeth of the transmission rod 12, the two points slide against each other without causing the transmission rod 12 to move upward.

[0038] In addition, both the ratchet 13 and the pawl 14 are provided with springs that push them tightly against the transmission rod 12, enabling good engagement with the ratchet teeth of the transmission rod 12. When the ratchet 13 rotates forward, under the action of the spring, the ratchet 13 closely adheres to the transmission rod 12, effectively driving the transmission rod 12 to move downward. The cooperation between the transmission rod 12 and the pawl 14 causes the pawl 14 to swing clockwise and compress its spring, enabling the transmission rod 12 to move downward. When the ratchet 13 rotates reversely, the ratchet 13 moves away from the transmission rod 12 and compresses its spring, allowing the ratchet 13 to rotate reversely normally. At this time, the spring of the pawl 14 pushes it tightly against the transmission rod 12 to prevent the transmission rod 12 from moving upward. Since the structures of the ratchet 13, pawl 14, and ratchet teeth are common knowledge, they are not shown in the drawings.

[0039] In this embodiment, a cylinder 18 for driving the lifting of the pushing head 1 is provided in cooperation. The cylinder 18 is provided with a pushing air inlet and a retracting air inlet. When the pushing air inlet is connected, the pushing head 1 is pushed out. When the retracting air inlet is connected, the pushing head 1 retracts. The cylinder body 15 is connected to the retracting air inlet. During sampling, the pushing air inlet is connected to the air source, causing the sampling spoon 2 to extend for sampling. At this time, the retracting air inlet is open. After sampling is completed, the retracting air inlet is connected to the air source, causing the sampling spoon 2 to retract. At the same time, the cylinder body 15 is also connected to the air source, causing the flipping part 6 to flip. Thus, one sampling is completed. To prevent samples from still falling after the flipping part 6 reverses, after sampling ends, first stop the rotation of the rotating rod so that the sampling spoon 2 no longer enters the sample and all the samples inside it fall. Then, make the flipping plate flip to the horizontal.

[0040] In this embodiment, the drill rod includes a drilling section 19, a control section 20, and a number of regular sections 21 connected in sequence. The drill bit 3 and the sample box 4 are provided in the drilling section 19. The driving part, the diversion groove 7, and the sampling mechanism are all provided inside the control section 20. The regular section 21 has no special function and can only be used to lengthen the drill rod. During the drilling process, as the drilling depth increases, the drill rod needs to be continuously lengthened. Therefore, initially, a set of the drilling section 19, the control section 20, and the regular section 21 are combined first. During the drilling process, the regular section 21 is continuously added.

[0041] In addition, this segmentation method also enables the air source to be connected only to the control section 20, while the drilling section 19 is used for drilling and placing the sample box 4. This avoids the trouble caused by connecting the air source to too many segments. At the same time, it is also convenient to take and place the sample box 4 after the drilling section 19 is removed.

[0042] In this embodiment, a weighing sensor 22 is also provided inside the drilling section 19. The weighing sensor 22 is provided at the bottom of the sample box 4. During the sampling process, the weight of the sampled sample can be judged by weighing, and thus it can be determined whether the sampling is completed.

[0043] The present invention also provides a mineral exploration sampling method, which is used in cooperation with the above-mentioned mineral exploration sampling device. The drill rod rotates and drills until the sampling spoon 2 reaches the sampling position. The pushing head 1 pushes the sampling spoon 2 to extend so that the sampling spoon 2 rotates for sampling. After sampling is completed, the pushing head 1 drives the sampling spoon 2 to retract. The driving part drives the driving rod 8 to descend a certain distance so that the lowermost turning part 6 turns to the horizontal state. The above method is used for sampling at the first point and turning the lowermost turning part 6. Subsequently, the above method is used for sampling at the second point and turning the next turning part 6 upwards in sequence. The above process is repeated until sampling is completed or the sample box 4 is full.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
