Description

Technical Field

[0001] The present application relates to the technical field of soil sampling, and in particular to a sampling device for mineral geological exploration. Background Art

[0002] Sampling devices for mineral geological exploration are mainly used to collect representative rock, mineral or soil samples from underground for detailed chemical analysis, physical testing and geological research.

[0003] Existing soil drilling sampling equipment generally has the problem of limited sampling tube length and frequent shutdown to increase the number of sampling tube connections when performing deep sampling operations, resulting in low sampling efficiency. In addition, traditional equipment lacks the automatic connection and recovery function of the sampling tube, and the degree of automation is low, which makes it difficult to meet the needs of fast, continuous and high-precision sampling in the field. In addition, after the sampling is completed, a large amount of soil is easily attached to the outer wall of the sampling tube, and the sample remains in the inner cavity. If it is not cleaned in time, it will affect the accuracy of subsequent sampling. However, existing equipment generally does not have the function of synchronously cleaning the inner and outer walls of the sampling tube, resulting in the sampling tube undergoing additional maintenance procedures before reuse, which extends the equipment's cycle operation period.

[0015] The beneficial effects of the present invention are as follows: 1. When the device is drilling downward for sampling, first start the pushing mechanism in the positive direction to make the clamping mechanism move downward to clamp the sampling tube in the middle of the loading mechanism, then start the rotating mechanism in the positive direction, the rotating mechanism will first drive the clamping mechanism to rotate, so that the sampling tube moves to the left side of the device, then start the driving mechanism in the positive direction, start the pushing mechanism in the reverse direction and the output shaft of the second driving member is self-locking. At this time, the pushing mechanism first drives the clamping mechanism to move the clamped left sampling tube upward through the shaft sleeve and connect it with the rotating connecting pipe thread. The pushing mechanism drives the clamping mechanism to drive the sampling tube through the driving mechanism through the shaft sleeve. The tube moves downward and connects with the sampling tube inserted into the soil below, thereby lengthening the sampling tube as a whole. At this time, the rotating connecting tube drives the lengthened sampling tube to rotate as a whole, and at the same time, the pushing mechanism is started in the positive direction, and the pushing mechanism pushes the clamping mechanism downward through the shaft sleeve. The clamping mechanism drives the lengthened sampling tube as a whole to move downward and rotate. At the same time, the clamping mechanism continues to clamp the new sampling tube on the rear side carrier mechanism, thereby realizing automatic extraction of the sampling tube on the carrier mechanism and automatic connection and extension of the sampling tube as a whole while drilling, so as to improve the depth sampling efficiency.

[0016] 2. After the drilling is completed, the clamping mechanism is in the lowest position, and the splint on the left side of the clamping mechanism keeps clamping the sampling tube. At this time, the driving mechanism and the pushing mechanism are started in reverse, so that the clamping mechanism drives the sampling tube to move upward to the top. At the same time, the brush cleans the outer surface of the sampling tube, and the internal washing mechanism cleans the inner cavity of the sampling tube on the right side, so that the sampling tube can be reused when sampling next time to avoid cross infection of the soil. Then stop starting the pushing mechanism and start the rotating mechanism in reverse. The rotating mechanism drives the passive gear to rotate through the active gear, and the passive gear drives the rotating sleeve, the limit groove, the slider, the elastic block and the splint. The clamped sampling tube rotates in the opposite direction, so that the sampling tube clamped by the left splint of the clamping mechanism is separated from the connecting tube and the sampling tube below. The connecting tube and the sampling tube below are no longer limited by the sampling tube clamped by the left splint of the clamping mechanism to limit the rotation of the clamping mechanism. At this time, the rotating mechanism drives the rotating disk to rotate, so that the sampling tube on the left side moves to just above the front soil discharge hole. Then the pushing mechanism is started in the positive direction, and the pushing mechanism pushes the clamping mechanism downward through the connecting seat. The soil in the front sampling tube is pushed into the packaging device for packaging through the pushing mechanism, and the cleaned sampling tube on the rear side is pushed back to the middle of the carrying mechanism, thereby realizing automatic decomposition, recovery and cleaning of the sampling tube as a whole.

[0022] See also Figures 1 to 4 As shown, the driving mechanism 3 includes a casing 301, which is fixedly sleeved on the left side of the middle part of the top plate 1, and an elastic member 302 is fixedly installed on the top end of the inner cavity of the casing 301, and a sleeve rod 303 is fixedly installed on the bottom end of the elastic member 302.

A connecting pipe 305 is fixedly installed on the output end of the first driving member 304. The casing 301 and the sleeve rod 303 are both rectangular in shape.

[0023] When in use, the first driving member 304 is first started in the forward direction, and the output end of the first driving member 304 drives the connecting tube 305 to rotate, and then the clamping mechanism 11 first drives the clamped left sampling tube to move upward and contact the connecting tube 305, so that the left sampling tube clamped by the clamping mechanism 11 is threadedly connected to the connecting tube 305, and then the clamping mechanism 11 drives the connecting tube 305 and the first driving member 304 to move downward through the sampling tube connected to the connecting tube 305, and the first driving member 304 pulls the elastic member 302 to extend through the sleeve rod 303. At this time, the sampling tube connected to the connecting tube 305 moves downward and is connected to the sampling tube inserted into the soil below, thereby lengthening the sampling device.

[0024] See also Figures 1 to 3As shown, the pushing mechanism 4 includes a hydraulic sleeve 401, which is fixedly sleeved on the middle part of the top plate 1, and an input liquid pipe 402 is fixedly sleeved on the right side of the hydraulic sleeve 401. A telescopic rod 403 is slidably sleeved on the bottom of the inner cavity of the hydraulic sleeve 401, and a first threaded rod 404 is movably sleeved on the upper part of the telescopic rod 403. The first threaded rod 404 is threadedly connected to the upper part of the hydraulic sleeve 401, and a first gear 405 is slidably sleeved on the curved surface of the first threaded rod 404. A second threaded rod 406 is threadedly connected to the front side of the middle part of the top plate 1, a piston 407 is fixedly installed on the bottom end of the second threaded rod 406, and a second gear 408 is slidably sleeved on the upper part of the second threaded rod 406. The rear side of the middle part of the top plate 1 is threadedly connected with a third threaded rod 409, and the bottom end of the third threaded rod 409 is fixedly installed with an electromagnetic block 410. The upper part of the third threaded rod 409 is slidably sleeved with a third gear 411, and the second gear 408, the third gear 411 and the first gear 405 are meshed with each other. The piston 407 is located below the electromagnetic block 410. The middle part of the upper surface of the top plate 1 is fixedly installed with a limiting frame 412, the first threaded rod 404, the second threaded rod 406 and the third threaded rod 409 are slidably sleeved with the limiting frame 412, and the first gear 405, the second gear 408 and the third gear 411 are arranged between the limiting frame 412 and the upper surface of the top plate 1.

[0025] Among them, the diameter of the piston 407 is equal to the inner diameter of the sampling tube, the diameter of the electromagnetic block 410 is equal to the outer diameter of the sampling tube, and the distance between the bottom end of the piston 407 and the bottom end of the electromagnetic block 410 is equal to or greater than the height of a sampling tube, so that when the second threaded rod 406 drives the piston 407 to move downward to the bottom of the inner cavity of the front sampling tube, the third threaded rod 409 drives the electromagnetic block 410 to push the sampling tube clamped by the inner cavity clamping plate 1106 of the rear mounting hole of the rotating disk 1101 downward to the middle of the upper limit column 804 of the loading mechanism 8, so that the rear sampling tube is separated from the rear clamping plate 1106, thereby pushing the soil in the front sampling tube to the middle of the packaging device 6, and pushing the rear cleaned sampling tube into the loading mechanism 8. The diameter of the first gear 405 is the diameter of the second gear 408 and the third gear 41 1 is twice the diameter, so that when hydraulic oil is introduced into the inner cavity of the input liquid pipe 402, the telescopic rod 403 moves downward. The telescopic rod 403 drives the clamping mechanism 11 to move downward through the shaft sleeve 1005. At this time, the telescopic rod 403 pulls the first threaded rod 404 to move downward. The hydraulic sleeve 401 threadedly connected to the first threaded rod 404 pushes the first threaded rod 404 to rotate. The first threaded rod 404 drives the first gear 405 to rotate. The first gear 405 drives the second gear 408 and the third gear 411 to rotate. The second gear 408 drives the second threaded rod 406 to rotate. The second threaded rod 406 drives the piston 407 to move downward at twice the speed of the clamping mechanism 11, thereby achieving downward movement of the piston 407 relative to the clamping mechanism 11. The same applies to the third threaded rod 409 and the electromagnetic block 410.

[0026] See also Figure 1 and Figure 2 As shown, the loading mechanism 8 includes a hydraulic rod 801, which is fixedly sleeved in the middle of the telescopic seat 7. A curved plate 802 is fixedly mounted on the telescopic end of the hydraulic rod 801, and a loading plate 803 is fixedly mounted on one side of the curved plate 802. The loading plate 803 is slidably sleeved on the bottom of the inner cavity of the telescopic seat 7. A plurality of groups of limiting posts 804 are fixedly mounted at equal intervals on the upper surface of the loading plate 803. The curved surface of the limiting posts 804 is slidably sleeved with a sampling tube. During use, by starting the hydraulic rod 801 in the forward or reverse direction, the telescopic end of the hydraulic rod 801 drives the curved plate 802 to move to the left or right through the hydraulic rod 801, and the curved plate 802 drives the loading plate 803 or the sampling tube to move directly below the mounting hole on the rear side of the rotating disk 1101, so that the subsequent pushing mechanism 4 can extract or recover the sampling tube through the third threaded rod 409 and the electromagnetic block 410.

[0027] See also Figures 1 to 6 As shown, the rotating mechanism 10 includes a second driving member 1001, which is fixedly mounted on the middle part of the lower surface of the water tank 9. A sleeve 1002 is fixedly mounted on the output end of the water tank 9. A first friction wheel 1003 is fixedly sleeved on the bottom of the sleeve 1002. The first friction wheel 1003 is located at the bottom of the inner cavity of the water tank 9. A plurality of groups of brushes 1004 are fixedly mounted on the upper surface of the first friction wheel 1003 at equal intervals. The brushes 1004 are in contact with the sampling tube sleeved on the left side of the water tank 9. A shaft sleeve 1005 is slidably sleeved on the upper part of the sleeve 1002, and a driving gear 1006 is fixedly sleeved on the upper part of the curved surface of the shaft sleeve 1005.

[0028] Among them, the brush 1004 contacts the left sampling tube connected to the water tank 9, so that when the second driving member 1001 rotates, the output end of the second driving member 1001 drives the sleeve shaft 1002 to rotate, the sleeve shaft 1002 drives the first friction wheel 1003 to rotate, and the first friction wheel 1003 drives the brush 1004 to rotate. The brush 1004 cleans the outer surface of the left sampling tube in contact with it to avoid a large amount of dirt on the outer surface of the sampling tube, which causes the subsequent clamping mechanism 11 to slip when clamping the sampling tube. In addition, when the sleeve shaft 1002 rotates, the sleeve shaft 1002 drives the sleeve 1005 to rotate, the sleeve 1005 drives the driving gear 1006 to rotate, and the sleeve 1005 drives the telescopic rod 403 to rotate, and the telescopic rod 403 slides relative to the first threaded rod 404.

[0029] See also Figure 1 、 Figure 2 and Figure 5As shown, the clamping mechanism 11 includes a rotating disk 1101, which is fixedly sleeved on the upper part of the shaft sleeve 1005. The upper surface of the rotating disk 1101 is equidistantly provided with a plurality of mounting holes. The middle part of the mounting hole is movably sleeved with a rotating sleeve 1102. The inner curved surface of the rotating sleeve 1102 is equidistantly provided with a plurality of limiting grooves 1103. The middle part of the limiting groove 1103 is slidably sleeved with a slider 1104. An elastic block 1105 is fixedly installed on the inner side of the slider 1104. A splint 1106 is fixedly installed on the inner side of the elastic block 1105. A driven gear 1107 is fixedly installed on the top of the rotating sleeve 1102. The driven gear 1107 is meshed with the driving gear 1006. The inner curved surface of the clamping plate 1106 is provided with a rubber coating, thereby improving the stability of the clamping plate 1106 in clamping the sampling tube. The shape of the limiting groove 1103 is a U-arc, and the contact surface between the limiting groove 1103 and the slider 1104 is a smooth surface. The inner side of the bottom end of the clamping plate 1106 is provided with a chamfer, so that when the pushing mechanism 4 pushes the clamping mechanism 11 to move downward through the rotating mechanism 10, the top end of the sampling tube pushes the clamping plate 1106 through the chamfer opened at the bottom of the clamping plate 1106 to squeeze the elastic block 1105 to contract, and the sampling tube moves to In the middle part of the multiple groups of splints 1106, the contact surface between the rotating sleeve 1102 and the mounting hole is a rough surface, thereby increasing the friction resistance between the rotating sleeve 1102 and the mounting hole, so that when the rotating mechanism 10 drives the passive gear 1107 to rotate through the active gear 1006, the friction force between the rotating sleeve 1102 and the mounting groove is greater than the resistance of the passive gear 1107 to rotate the rotating disk 1101 through the rotating sleeve 1102, thereby realizing that the active gear 1006 drives the rotating disk 1101 to rotate through the passive gear 1107 and the slider 1104.

[0030] See also Figure 2 、 Figure 3 and Figure 6 As shown, the internal washing mechanism 12 includes a connecting shaft 1201, which is movably sleeved on the right side of the inner cavity of the water tank 9. The curved surface of the connecting shaft 1201 is fixedly sleeved with a second friction wheel 1202, and the second friction wheel 1202 is engaged with the first friction wheel 1003. A cleaning block 1203 is fixedly installed on the upper part of the connecting shaft 1201, and a curved pipe 1204 is provided in the middle between the connecting shaft 1201 and the cleaning block 1203.

[0031] Among them, the curved pipe 1204 is an inverted L-shape, so that when the rotating mechanism 10 drives the internal washing mechanism 12 to rotate, the curved pipe 1204 is under the action of centrifugation. When the upper part of the curved pipe 1204 throws out air, the bottom of the curved pipe 1204 attracts the water in the inner cavity of the water tank 9 to flow upward, and finally flows to the cleaning block 1203, so that the rotating cleaning block 1203 cleans the inner wall of the downward and upward moving sampling tube. The cleaning block 1203 is made of sponge to avoid scratching the inner wall of the sampling tube. When in use, the rotating mechanism 10 drives the second friction wheel 1202 to rotate through the first friction wheel 1003, the second friction wheel 1202 drives the connecting shaft 1201 to rotate, and the connecting shaft 1201 drives the cleaning block 1203 and the curved pipe 1204 to rotate. At this time, the curved pipe 1204 provides water to the cleaning block 1203, and the cleaning block 1203 cleans the inner wall of the sampling tube.

[0032] Working principle: When the device of the present invention is drilling downward for sampling, hydraulic oil is first introduced into the input liquid pipe 402 through the external liquid supply device, so that the pushing mechanism 4 is started in the forward direction, and the hydraulic oil flows into the inner cavity of the hydraulic sleeve 401 to push the telescopic rod 403 to move downward, and the telescopic rod 403 drives the shaft sleeve 1005 to move downward, and the shaft sleeve 1005 drives the clamping mechanism 11 to move downward through the rotating disk 1101 fixedly sleeved on its upper part. At the same time, since the bottom of the first threaded rod 404 is movably sleeved on the upper part of the telescopic rod 403, and the first threaded rod 404 is threadedly connected to the upper part of the hydraulic sleeve 401, when the telescopic rod 403 moves downward, the telescopic rod 403 drives the first threaded rod 404 to move downward and rotate, and the first threaded rod 404 drives the first gear 405 slidably sleeved therewith to rotate. At the same time, since the second threaded rod 406 and the third threaded rod 409 are threadedly connected to the top plate 1, the second threaded rod 406 is slidably sleeved with the second gear 408 and the third threaded rod 409 and the third gear 411 up and down. The diameter of the first gear 405 is twice the diameter of the second gear 408 and the third gear 411, so that the rotating first gear 405 drives the second gear 408 and the third gear 411 to rotate, and the second gear 408 drives the piston 407 to move downward at twice the speed of the clamping mechanism 11 through the second threaded rod 406. At this time, the piston 407 moves downward relative to the clamping mechanism 11. Similarly, the electromagnetic block 410 moves downward relative to the clamping mechanism 11. When the clamping mechanism 11 moves downward until it contacts the top of the sampling tube in the middle of the carrier mechanism 8, the electromagnetic block 410 is activated. The electromagnetic block 410 absorbs the sampling tube at its bottom and moves it upward to the middle of the multiple groups of clamping plates 1106 on the rear side of the clamping mechanism 11. At this time, the multiple groups of clamping plates 1106 on the rear side preliminarily clamp the sampling tube. Then, the rotating mechanism 10 is started in the positive direction, and the active gear 1006 of the rotating mechanism 10 transmits the rotating torque to the rotating sleeve 1102 through the passive gear 1107. Since the rotating sleeve 1102 is in frictional contact with the mounting hole provided by the clamping mechanism 11, the rotating sleeve 1102 and the mounting hole are in a stuck state, that is, the rotating sleeve 1102 and the mounting hole remain relatively stationary. At this time, the rotating mechanism 10 started in the positive direction preferentially drives the clamping mechanism 11 to rotate, so that the clamping mechanism 11 drives the sampling tube on the rear side to move to the left side of the device, and then the driving mechanism 3 is started in the positive direction, that is, the driving mechanism 3 drives the connecting tube 305 to rotate in the positive direction, and the pushing mechanism 4 is started in the reverse direction, that is, the telescopic rod 403 of the pushing mechanism 4 drives the clamping mechanism 11 to move upward through the shaft sleeve 1005, and the clamping mechanism 11 drives the sampling tube to move upward, and self-locks with the output shaft of the second driving member 1001, that is, the second driving member 1001 limits the rotation of the clamping mechanism 11, and at this time, the pushing mechanism 4 first The clamping mechanism 11 drives the clamped left sampling tube to move upward through the shaft sleeve 1005 and is threadedly connected to the rotating connecting tube 305. At the same time, the connecting tube 305 drives the slider 1104 to rotate through the sampling tube, the clamping plate 1106 that clamps the sampling tube and the elastic block 1105, so that the slider 1104 moves to the edge position of the limit groove 1103, compressing the elastic block 1105, thereby increasing the clamping force and friction between the clamping plate 1106 and the clamped sampling tube, thereby achieving the subsequent positive start-up of the pushing mechanism 4 and the second driving member 1001 to release the self-locking when the power is cut off. The pushing mechanism 4 enables the clamping mechanism 11 to drive the connecting tube 305 and the first driving member 304 to move downward through the sampling tube through the shaft sleeve 1005. The first driving member 304 pulls the elastic member 302 to extend through the sleeve rod 303. At this time, the sampling tube connected to the connecting tube 305 moves downward and is connected to the sampling tube inserted into the soil below, thereby achieving the overall lengthening of the sampling tube. At this time, the rotating connecting tube 305 drives the extended sampling tube to rotate as a whole, and at the same time, the pushing mechanism 4 is started in the forward direction. The pushing mechanism 4 pushes the shaft sleeve 1005 through the telescopic rod 403 at the bottom thereof, driving the clamping mechanism 11 to move downward. The clamping mechanism 11 drives the extended sampling tube to move downward and rotate as a whole. At the same time, the clamping mechanism 11 continues to clamp the new sampling tube in the middle of the rear loading mechanism 8. At this time, the sampling tube clamped on the left side of the clamping mechanism 11 is clamped by the clamping mechanism 11. At the same time, the sampling tube clamped on the left side of the clamping mechanism 11 is threadedly connected to the sampling tube fixed to the soil below it. Then, the first driving member 304 is started in the reverse direction. The connecting tube 305 is separated from the left sampling tube that is threadedly connected to it and is clamped by the clamping mechanism 11. Then, when the rotating mechanism 10 is reversely started, the driving gear 1006 on the upper part of the rotating mechanism 10 drives the driven gear 1107 to rotate in the opposite direction, so that the clamping plate 1106 and the left sampling tube are loosened. Then, the pushing mechanism 4 is reversely started, and the pushing mechanism 4 drives the rear sampling tube upward through the shaft sleeve 1005 and the clamping mechanism 11. The same operation as above is repeated, thereby realizing automatic extraction of the sampling tube on the loading mechanism 8 and automatic connection and extension of the sampling tubes as a whole while drilling, so as to improve the depth sampling efficiency; In addition, in the present invention, after the drilling is completed, when the sampling tube is taken out of the soil in sections, the clamping mechanism 11 is moved to the lowest position, and the clamping plate 1106 on the left side of the clamping mechanism 11 keeps the sampling tube in a clamping state. During the process of reverse starting the driving mechanism 3 and the reverse starting the pushing mechanism 4, the driving mechanism 3 drives the sampling tube to rotate in the opposite direction. The sampling tube drives the passive gear 1107 to rotate through the clamping plate 1106, the elastic block 1105, the slider 1104 and the limiting groove 1103, and the passive gear 1107 drives the active gear 1006 to rotate. The active gear 1006 drives the shaft sleeve 1005 to rotate, and the shaft sleeve 1005 drives the sleeve shaft 1007 to rotate. 02 rotates, the sleeve shaft 1002 drives the first friction wheel 1003 to rotate, the first friction wheel 1003 drives the brush 1004 to rotate, and at the same time the first friction wheel 1003 drives the internal washing mechanism 12 to rotate, the pushing mechanism 4 drives the clamping mechanism 11 to move upward through the rotating mechanism 10, and the clamping mechanism 11 drives the sampling tube to move upward to the top as a whole, so that the brush 1004 cleans the outer surface of the sampling tube. At the same time, when the sampling tube is clamped in the middle of the multiple groups of clamps 1106 on the right side of the clamping mechanism 11, the internal washing mechanism 12 cleans the inner cavity of the sampling tube in contact with it, thereby cleaning the inner and outer walls of the sampling tube; Then, the pushing mechanism 4 is stopped and started. At this time, the sampling tube clamped by the left clamping plate 1106 of the clamping mechanism 11 is threadedly connected to the connecting tube 305 above it and the sampling tube below it. At this time, the second driving member 1001 is restricted from rotating. At this time, the first driving member 304 is self-locked and the rotating mechanism 10 is started in the reverse direction. The rotating mechanism 10 drives the driven gear 1107 to rotate through the active gear 1006. The driven gear 1107 drives the clamped sampling tube to rotate in the opposite direction through the rotating sleeve 1102, the limiting groove 1103, the slider 1104, the elastic block 1105 and the clamping plate 1106, so that the sampling tube clamped by the left clamping plate 1106 of the clamping mechanism 11 is separated from the connecting tube 305 and the sampling tube below. After that, the connecting tube 305 and the sampling tube below are no longer limited by the sampling tube clamped by the left clamping plate 1106 of the clamping mechanism 11. At this time, due to the friction contact between the rotating sleeve 1102 and the mounting hole of the clamping mechanism 11, the rotating mechanism 10 The sleeve 1102 and the mounting hole are in a stuck state, that is, the rotating sleeve 1102 and the mounting hole remain relatively stationary, and the rotating mechanism 10 drives the rotating disk 1101 to rotate, so that the sampling tube on the left side moves to just above the front soil discharge hole 501, and then the pushing mechanism 4 is started in the positive direction. The pushing mechanism 4 pushes the clamping mechanism 11 to move downward through the connecting seat 5, and the second threaded rod 406 pushes the piston 407 to move downward at twice the speed of the clamping mechanism 11 downward. At this time, the piston 407 moves downward relative to the clamping mechanism 11. Similarly, the electromagnetic block 410 moves downward relative to the clamping mechanism 11. When the clamping plate 1106 on the left side of the clamping mechanism 11 moves downward to clamp the sampling tube on the left, the piston 407 pushes the soil in the front sampling tube into the packaging device 6 for packaging, and the electromagnetic block 410 pushes the cleaned sampling tube on the rear side back to the middle of the loading mechanism 8, thereby realizing automatic decomposition, recycling and cleaning of the sampling tube as a whole.
