DETAILED DESCRIPTION

[0025] In order to make the purpose, 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 drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Example:

[0027] like Figure 1-5 As shown, the present invention provides a mineral exploration sampling device, including a drill rod and a sampling mechanism arranged inside the drill rod. The sampling mechanism includes a pushing head 1 and a plurality of sampling spoons 2. The pushing head 1 is in a truncated cone shape, and a cylinder 18 is arranged at one end thereof. The cylinder 18 can be used to drive the lifting thereof. In addition to the cylinder 18, a motor bearing component can also be arranged. In this embodiment, the cylinder 18 is selected. The drill rod is in a tubular shape. In order to control the movement of the cylinder 18, an air pipe is also penetrated inside the drill rod. The air pipe gradually extends downward along with the drill rod, and one end thereof is exposed to the ground, so that ground personnel can perform ventilation control conveniently.

[0028] The side wall of the drill rod is provided with a plurality of through holes. Each of the plurality of sampling spoons 2 is slidably disposed inside a through hole so that the sampling spoon 2 can extend out of the outer wall of the drill rod or retract into the inside of the drill rod. Figure 1 and 2As shown, when the sampling spoon 2 is retracted, its outer surface is flush with the outer surface of the drill rod, thereby closing the through hole of the drill rod to prevent impurities from entering the inside of the drill rod through the through hole during rotation. The pushing head 1 is arranged in conjunction with a plurality of sampling spoons 2. Specifically, the sampling spoon 2 is arranged in an inclined shape in conjunction with the pushing head 1, so that the extension and retraction 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 correspondingly 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 sampling spoon 2 and the pushing head 1 have the same movement. At the same time, in order to ensure the telescopic stability of the sampling spoon 2 relative to the through hole, the contact position of 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 rod.

[0029] When the mineral exploration sampling device of the present invention is used, the drill rod drives the drill bit 3 to rotate, so that the drill bit 3 gradually drills downward. When the sampling spoon 2 follows the drilling to the sampling depth, the pushing head 1 pushes a plurality of sampling spoons 2 through the through hole of the drill rod to the outside of the drill rod by ventilating the inside of the cylinder 18, so that the sampling spoon 2 contacts the hole wall during the rotation, and then collects samples such as ore or soil in the stratum into the sampling spoon 2. After the sampling is completed, the cylinder 18 is ventilated in the reverse direction, so that the pushing head 1 retracts and brings the sampling spoon 2 back to the inside of the drill rod. The sample retained in the sampling spoon 2 can be taken out by taking out the drill rod. This allows drilling and sampling to be carried out simultaneously, avoiding the trouble of lifting the drill rod to replace the sampling device.

[0030] In this embodiment, a sample box 4 is also included. The sample box 4 is arranged inside the drill rod and between the sampling mechanism and the drill bit 3. In other words, the sample box 4 is located below the sampling mechanism, so that the sampled sample falls into the sample box 4, thereby better storing the sample. The size of the sample box 4 is smaller than the inner diameter of the drill rod, so that the sample box 4 can be placed inside the drill rod. This also makes it easy to take out the sample box 4, thereby facilitating the removal of the sample inside the sample box 4.

[0031] In this embodiment, the sample box 4 is provided with a plurality of partitions from top to bottom, so that the interior of the sample box 4 is divided into a plurality of chambers by the plurality of partitions. Figure 5 As shown, the partition includes a fixed portion 5 and a flip portion 6 hinged to the fixed portion 5. Several flip portions 6 are arranged in the same straight line, so that when all the flip portions 6 are flipped up, the sample can fall to the bottom through the top of the sample box 4. A guide groove 7 is also provided inside the drill rod. The guide groove 7 is funnel-shaped, and it is arranged in conjunction with the sampling spoon 2 and the sample box 4. Specifically, the guide groove 7 is arranged below the sampling spoon 2 and above the sample box 4, so that the sample of the sampling spoon 2 flows into the inside of the sample box 4 through the guide groove 7. The outlet of the guide groove 7 is located above the certificate of the flip portion 6. The flip portion 6 is also provided with a driving mechanism for driving it to flip.

[0032] When sampling, the sampling spoon 2 rotates to sample. The obtained sample enters the guide groove 7 and finally flows into the interior of the sample box 4. Initially, all the flip parts 6 are flipped up, and the sample first falls to the bottom of the sample box 4. After the first sampling is completed, the lowest flip part 6 is driven by the driving mechanism to flip to a horizontal position, so that the lowest chamber of the sample box 4 is closed. When sampling next time, the same method is used for sampling, and the sample at this time will fall onto the flipped flip part 6 and the corresponding fixed part 5. In other words, the two adjacent chambers above and below are isolated, so that the samples sampled each time are isolated from each other.

[0033] In this embodiment, the driving mechanism includes a driving rod 8, a winding wheel 9 and a pull rope 10. Figure 4 As shown, the pull rope 10 is connected to the winding wheel 9 and the flipping part 6, so that when the winding wheel 9 winds the pull rope 10, the flipping part 6 flips from the flipped state to the flat state. Each flipping part 6 is correspondingly provided with a set of winding wheels 9 and pull ropes 10. Thus, each flipping part 6 is controlled separately. The rotating shaft of the winding wheel 9 is provided with transmission teeth. The driving rod 8 is provided with a set of driving teeth 11 in coordination with the transmission teeth of each winding wheel 9. The movement of the driving rod 8 will drive the winding wheel 9 to rotate, and then retract the pull rope 10. The spacing between two adjacent sets of driving teeth 11 is relatively set, so that when the driving rod 8 advances a driving spacing, several winding wheels 9 from bottom to top successively wind a section of the corresponding pull rope 10. Specifically, the distribution length of a set of driving teeth 11 on the driving rod 8 is set to be a propulsion length. In the initial state, the lowest driving tooth 11 just meshes with the lowest winding wheel 9. After the driving rod 8 is pushed downward by a propulsion length, the lowest driving tooth 11 just completely passes through the lowest winding wheel 9. At this time, a group of driving teeth 11 adjacent to the lowest driving tooth 11 just meshes with the winding wheel 9 adjacent to the lowest winding wheel 9. And going up successively, the distance between the upper driving teeth 11 and the upper winding wheel 9 is just one propulsion length. The distance between the next group of driving teeth 11 and the winding wheel 9 is two propulsion lengths. In other words, each time the driving rod 8 is pressed and the pressing length is one propulsion length, the plurality of flipping parts 6 are flipped from bottom to top in sequence to the horizontal.

[0034] Based on this, after each sampling is completed, pressing the driving rod 8 once can cause the corresponding flipping part 6 to flip once, and then the newly sampled sample is sealed in the chamber below. A set of driving teeth 11 drives the corresponding winding wheel 9 to rotate just enough to drive the flipping part 6 to flip to an acute angle with the horizontal plane, so that it can fall to the horizontal under the action of gravity. In order to better ensure that the flipping part 6 will not lose control and flip to the horizontal during use, the state of the flipping part 6 when flipped up is as follows 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, the ratchet 13 and the pawl 14 are both provided with springs that push them tightly against the transmission rod 12, so that they can mesh well with the ratchet teeth of the transmission rod 12. When the ratchet 13 rotates forward, the ratchet 13 is well pressed against the transmission rod 12 under the action of the spring, thereby effectively driving the transmission rod 12 to move downward, and the cooperation between the transmission rod 12 and the pawl 14 makes the pawl 14 swing clockwise to compress its spring, thereby 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, so that the ratchet 13 can rotate normally in the reverse direction, and 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, the pawl 14 and the ratchet teeth are common knowledge, they are no longer shown in the accompanying drawings.

[0039] In this embodiment, the pushing head 1 is provided with a cylinder 18 for driving the pushing head 1 to rise and fall. 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 is retracted. The cylinder body 15 is connected to the retracting air inlet. When sampling, the air source is connected to the pushing air inlet so that the sampling spoon 2 is extended to sample. At this time, the retracting air inlet is open. After the sampling is completed, the retracting air inlet is connected to the air source so that the sampling spoon 2 is retracted. At the same time, the cylinder body 15 is also connected to the air source, so that the flip part 6 is flipped. Then a sampling is completed. In order to prevent the sample from falling after the flip part 6 is reversed, the rotation of the rotating rod is stopped after the sampling is completed, so that the sampling spoon 2 no longer enters the sample and all the samples inside it fall out. Then the flip plate is flipped to the horizontal.

[0040] In this embodiment, the drill rod includes a drilling section 19, a control section 20 and a plurality of conventional sections 21 connected in sequence. The drill bit 3 and the sample box 4 are arranged in the drilling section 19. The driving part, the guide groove 7 and the sampling mechanism are all arranged inside the control section 20. The conventional section 21 does not have a special function and can only be used to lengthen the drill rod. During the drilling process, as the drilling deepens, the drill rod needs to be continuously lengthened. Therefore, initially, a set of drilling sections 19, control sections 20 and conventional sections 21 are combined. Conventional sections 21 are continuously added during the drilling process.

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

[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 sample obtained by sampling can be determined by weighing, and then it can be determined whether the sampling is completed.

[0043] The present invention also provides a mineral exploration sampling method, which is used in conjunction 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 the sampling is completed, the pushing head 1 drives the sampling spoon 2 to retract. The driving unit drives the driving rod 8 to descend a certain distance so that the bottom flip part 6 flips to a horizontal state. The above method is used to perform sampling at the first point and flip the bottom flip part 6. Then the above method is used to perform sampling at the second point and flip the next flip part 6 upward in turn. Repeat the above process until the sampling is completed or the sample box 4 is full.

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