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

[0029] like Figures 1 to 10As shown, a support baffle 217 is fixedly installed in the sampling outer cylinder 201, a positioning support rod 218 is fixedly installed in the sampling outer cylinder 201, a transmission gear ring 206 is fixedly installed on the top of the excavation inner cylinder 202, and the inner ring of the transmission gear ring 206 is provided with a gear pattern, an excavation transmission rod 205 is longitudinally rotatably installed in the positioning support rod 218, a gear is fixedly installed at the bottom of the excavation transmission rod 205, and the gear at the bottom of the excavation transmission rod 205 is meshed with the gear pattern of the inner ring of the transmission gear ring 206, the control mechanism 1 includes a support slide 102, the support slide 102 is longitudinally slidably installed inside the sampling outer cylinder 201, a discharge cover plate 101 is fixedly installed on the top of the support slide 102, a first drive motor 104 and a second drive motor 105 are fixedly installed in the discharge cover plate 101, and a first drive motor 104 and a second drive motor 105 are fixedly installed in the discharge cover plate 101.

[0030] like Figures 1 to 10 As shown, a sampling pipe 203 is fixedly installed on the top of the excavation inner cylinder 202, and a plurality of clamping claw slide grooves are arranged on the sampling pipe 203. A plurality of sampling support plates 204 are installed on the inner wall of the sampling pipe 203 to support the bottom of the intercepted geological samples, so as to facilitate the extraction of the samples to the surface. A counterweight block 215 is fixedly installed on the top of the inner wall of the sampling support plate 204, and a positioning support block 220 is fixedly installed on the bottom of the inner wall of the sampling support plate 204, which is used to control the sampling support plate 204 to rotate to a horizontal angle in the sampling pipe 203, so as to facilitate the extraction of the samples to the surface. The geological samples are cut off and supported, and a discharge inner cylinder 103 is fixedly installed in the supporting slide cylinder 102. The bottom of the discharge inner cylinder 103 is an inner and outer sleeve. The inner sleeve of the discharge inner cylinder 103 slides with the outer wall of the sampling pipe 203. A plurality of clamping triangular sliders 108 are installed in the sleeve inside the discharge inner cylinder 103 for horizontal sliding. A compression spring is fixedly installed between the clamping triangular slider 108 and the discharge inner cylinder 103. The clamping triangular slider 108 is used to clamp the intercepted samples to prevent the geological samples from slipping in the equipment.

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

[0032] like Figures 1 to 10 As shown, the outer sleeve of the discharge inner cylinder 103 is slidably matched with the support baffle 217, and a bulk material transmission 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 slide cylinder 102, and the bulk material transmission channel 110 is connected with the bulk material transmission trough 216, and a bulk material discharge port 109 is fixedly installed on the top of the discharge cover plate 101, and the bulk material discharge port 109 is connected with the bulk material transmission channel 110, which is used to discharge loose geological samples outside the exploration cave for easy collection.

[0033] like Figures 1 to 10 As shown, a support handle is fixedly installed on the top of the discharge cover plate 101, and a control switch is fixedly installed on the support handle. The support handle 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-up and height adjustment of the equipment.

[0034] Working principle: When conducting geological sampling, the staff holds the support handle on the top of the discharge cover plate 101 to place the excavation inner cylinder 202 at the drilling position, and then starts the first drive motor 104 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 the sliding position of the excavation claw 208 in the hollow excavation claw 207, and the excavation claw 208 is controlled to slide toward the outer circle of the excavation inner cylinder 202 in the hollow excavation claw 207. The feed port at the bottom of the excavation inner cylinder 202 is opened to intercept the drilled geological samples, and the excess loose samples are transmitted to the bulk material transmission channel 110 through the bulk material transmission slot 216, and are exported to the surface through the bulk material discharge port 109.

[0035] If it is necessary to perform fixed-point intermittent sampling of samples at different depths, the adjusting telescopic rod 210 is started during the drilling process to drive the adjusting excavation claw 208 to slide toward the axis in the hollow excavation claw 207, closing the feed port at the bottom of the excavation inner cylinder 202, and at the same time, the sliding excavation tooth 209 is pushed out to the outside of the adjusting excavation claw 208 by the reset push rod 214 to drill the borehole, and then the second drive motor 105 is started to drive the adjusting screw 106 to rotate, adjust the distance between the excavation inner cylinder 202 and the discharge cover plate 101, and increase the drilling depth of the excavation inner cylinder 202. When the excavation inner cylinder 202 is drilled to the required depth, the adjusting telescopic rod 210 is started to open the feed port at the bottom of the excavation inner cylinder 202, and geological samples in the area can be sampled.

[0036] When drilling and sampling relatively soft strata, the excavation inner cylinder 202 is drilled to a position deeper than the sampling depth, so that the sample at the required depth is higher than the sampling support plate 204 at the bottom of the inner wall of the sampling pipe 203. The equipment is then lifted out of the borehole. During this period, excess samples in the excavation inner cylinder 202 are detached from the excavation inner cylinder 202. At the same time, the sampling support plate 204 is driven by the counterweight block 215 to rotate to a horizontal angle in the sampling pipe 203, thereby lifting the sample inside the sampling pipe 203 to avoid the loss of the required soft sample.
