Description

Technical Field

[0001] The present invention relates to the technical field of geological exploration, and particularly relates to a sampler for geological exploration. Background Art

[0002] Geological exploration is to explore and detect the geological structure or the distribution of mineral resources on or under the ground through different methods.

[0003] During the geological exploration process, it is necessary to sample geological structures at different depths according to different requirements and actual situations. However, due to the different qualities of geological samples at different depths, if the size of the intercepted samples is not adjusted, it is difficult to take them out due to the weight of the samples. At the same time, it is difficult to ensure the integrity of the samples when sampling and collecting soft geological samples, resulting in difficult detection.

[0027] As Figures 1 to 10As shown in the figure, a sampler for geological exploration includes a sampling mechanism 2. A control mechanism 1 is longitudinally slidably installed at the top of the sampling mechanism 2. The sampling mechanism 2 includes a sampling outer cylinder 201. A digging inner cylinder 202 is longitudinally rotatably installed at the bottom of the sampling outer cylinder 201. A plurality of hollow digging claws 207 are fixedly installed at the bottom of the digging inner cylinder 202. The plurality of hollow digging claws 207 form an annular drill probe. A feeding port is provided at the center of the annular drill probe for intercepting geological samples. An adjusting digging claw 208 is transversely slidably installed inside the hollow digging claw 207. The adjusting digging claw 208 slides along the radial direction of the digging inner cylinder 202 to adjust the diameter of the intercepted sample, so as to adjust the drilling area according to the difficulty of ground drilling, improve the drilling efficiency. A plurality of sliding digging teeth 209 are longitudinally slidably installed inside the adjusting digging claw 208. A compression spring is fixedly installed between the top of the sliding digging tooth 209 and the adjusting digging claw 208. A support baffle 212 is fixedly installed at the top of the adjusting digging claw 208. The support baffle 212 is used to clamp the intercepted sample for subsequent extraction. An adjusting telescopic rod 210 is fixedly installed between the outer wall of the support baffle 212 and the inner wall of the digging inner cylinder 202. A plurality of arc-shaped baffles 211 are fixedly installed on the inner wall of the digging inner cylinder 202. The arc-shaped baffle 211 is in contact and cooperation with the support baffle 212 to form an intercepting pipeline for transmitting relatively soft geological samples and preventing the samples from spreading inside the equipment and affecting the operation of the equipment.

[0028] As Figures 1 to 10 shown, a reset push rod 214 is fixedly installed inside the hollow digging claw 207. A reset slider 219 is fixedly installed at the top of the sliding digging tooth 209. A pressing block is provided at the front end of the reset slider 219, and a pressing groove is provided at the rear end of the reset slider 219. The pressing blocks and pressing grooves between the plurality of reset sliders 219 are in contact and cooperation with each other. A chute is provided inside the reset push rod 214. The width of the chute inside the reset push rod 214 is the same as that of the reset slider 219. The bottom of the reset push rod 214 is in contact and cooperation with the top of the reset slider 219 to adjust the extension and retraction of the sliding digging tooth 209 at the bottom of the adjusting digging claw 208 and prevent the sliding digging tooth 209 from hindering the sliding of the adjusting digging claw 208 inside the hollow digging claw 207.

[0029] As Figures 1 to 10As shown in the figure, a support baffle 217 is fixedly installed inside the sampling outer cylinder 201, and a positioning support rod 218 is fixedly installed inside the sampling outer cylinder 201. A transmission gear ring 206 is fixedly installed at the top of the excavation inner cylinder 202. The inner ring of the transmission gear ring 206 is provided with gear teeth. A digging transmission rod 205 is longitudinally and rotatably installed inside the positioning support rod 218. A gear is fixedly installed at the bottom of the digging transmission rod 205. The gear at the bottom of the digging transmission rod 205 meshes with the gear teeth on the inner ring of the transmission gear ring 206. The control mechanism 1 includes a support sliding cylinder 102. The support sliding cylinder 102 is longitudinally slidably installed inside the sampling outer cylinder 201. An outlet cover plate 101 is fixedly installed at the top of the support sliding cylinder 102. A first drive motor 104 and a second drive motor 105 are fixedly installed inside the outlet cover plate 101. A hollow transmission rod 107 is fixedly installed on the output shaft of the first drive motor 104. The hollow transmission rod 107 is slidably matched with the digging transmission rod 205 and is used to drive the hollow transmission rod 107 to rotate through the first drive motor 104. The rotation of the hollow transmission rod 107 drives the digging transmission rod 205 to rotate. The rotation of the digging transmission rod 205 drives the excavation inner cylinder 202 to rotate inside the sampling outer cylinder 201 for drilling. A regulating lead screw 106 is fixedly installed on the output shaft of the second drive motor 105. The regulating lead screw 106 is in screw fit with the positioning support rod 218 and is used to drive the regulating lead screw 106 to rotate through the second drive motor 105. By the screw fit between the regulating lead screw 106 and the positioning support rod 218, the height of the equipment is adjusted to facilitate sampling of geological samples at different depths.

[0030] As Figures 1 to 10 shown in the figure, a sampling pipeline 203 is fixedly installed at the top of the excavation inner cylinder 202. Multiple jaw chutes are provided on the sampling pipeline 203. Multiple sampling support plates 204 are horizontally and rotatably installed on the inner wall of the sampling pipeline 203 and are used to support the bottom of the intercepted geological samples to facilitate the extraction of the samples to the ground surface. A counterweight block 215 is fixedly installed at the top of the inner wall of the sampling support plate 204. A positioning support block 220 is fixedly installed at the bottom of the inner wall of the sampling support plate 204 and is used to control the sampling support plate 204 to rotate to a horizontal angle inside the sampling pipeline 203 to facilitate the truncation and bottom support of the geological samples. An outlet inner cylinder 103 is fixedly installed inside the support sliding cylinder 102. The bottom of the outlet inner cylinder 103 is a two-layer sleeve. The inner sleeve of the outlet inner cylinder 103 is slidably matched with the outer wall of the sampling pipeline 203. Multiple clamping triangular sliders 108 are horizontally slidably installed inside the inner sleeve of the outlet inner cylinder 103. Compression springs are fixedly installed between the clamping triangular sliders 108 and the outlet inner cylinder 103. The clamping triangular sliders 108 are used to clamp the intercepted samples to prevent the geological samples from slipping inside the equipment.

[0031] As Figures 1 to 10As shown, a bulk material transfer groove 216 is provided on the outer wall of the excavation inner cylinder 202 for transferring the drilled loose samples from the borehole to the outside. A plurality of bulk material collection plates 213 are fixedly installed at the bottom of the excavation inner cylinder 202. The number of the bulk material collection plates 213 is the same as that of the bulk material transfer grooves 216. The bulk material collection plates 213 are fixedly installed between the bottoms of two bulk material transfer grooves 216 for collecting the drilled loose samples into the bulk material transfer grooves 216.

[0032] As Figures 1 to 10 shown, the outer sleeve of the discharge inner cylinder 103 is in sliding fit with the support baffle 217. A bulk material transfer channel 110 is provided between the outer wall of the outer sleeve of the discharge inner cylinder 103 and the inner wall of the support sliding cylinder 102. The bulk material transfer channel 110 is communicated with the bulk material transfer groove 216. A bulk material discharge port 109 is fixedly installed at the top of the discharge cover plate 101. The bulk material discharge port 109 is communicated with the bulk material transfer channel 110 for discharging the loose geological samples to the outside of the exploration hole for convenient collection.

[0033] As Figures 1 to 10 shown, a support handle is fixedly installed at the top of the discharge cover plate 101. A control switch is fixedly installed on the support handle and is connected to the first drive motor 104, the second drive motor 105 and the adjustment telescopic rod 210 through wires to control the start and height adjustment of the equipment.

[0034] Working principle: When conducting geological sampling, the excavation inner cylinder 202 is placed at the drilling position by the staff holding the support handle at the top of the discharge cover plate 101. Then, the first drive motor 104 is started to drive the excavation inner cylinder 202 to rotate in the sampling outer cylinder 201 to drill the geology. During this period, the adjustment telescopic rod 210 is started as needed to control and adjust the sliding position of the excavation claw 208 in the hollow excavation claw 207, and control and adjust the excavation claw 208 to slide towards the outer circle of the excavation inner cylinder 202 in the hollow excavation claw 207 to open the feed port at the bottom of the excavation inner cylinder 202 to intercept the drilled geological samples. The excess loose samples are transferred into the bulk material transfer channel 110 through the bulk material transfer groove 216 and are exported to the ground surface through the bulk material discharge port 109.

[0035] When it is necessary to take fixed-point intermittent samples of samples at different depths, during the drilling process, the adjustable telescopic rod 210 is activated to drive the adjustable digging claw 208 to slide towards the axis inside the hollow digging claw 207, closing the feed port at the bottom of the digging inner cylinder 202. At the same time, the sliding digging teeth 209 are pushed out of the adjustable digging claw 208 through the reset push rod 214 to drill the borehole. After that, the second drive motor 105 is activated to drive the adjustable screw rod 106 to rotate, adjusting the distance between the digging inner cylinder 202 and the discharge cover plate 101 to increase the drilling depth of the digging inner cylinder 202. When the digging inner cylinder 202 drills to the required depth, the adjustable telescopic rod 210 is activated to open the feed port at the bottom of the digging inner cylinder 202, and the geological samples in this area can be sampled.

[0036] When drilling and sampling a relatively soft formation, the digging inner cylinder 202 is drilled to a position deeper than the sampling depth, so that the samples at the required depth are higher than the sampling tray 204 at the bottom of the inner wall of the sampling pipe 203. Then the equipment is lifted out of the borehole. During this period, the excess samples in the digging inner cylinder 202 are separated from the digging inner cylinder 202. At the same time, the counterweight 215 drives the sampling tray 204 to rotate to a horizontal angle inside the sampling pipe 203, lifting the samples inside the sampling pipe 203 to prevent the required soft samples from being lost.
