[0002] Geological exploration sampling is an important link in geological exploration, aiming to obtain representative geological samples for analysis, identification or technical testing. In actual geological exploration work, it is necessary to ensure the representativeness of the samples during sampling, and record information such as sampling location and number in detail to provide a reliable basis for subsequent analysis and research. There are a large number of mining sections or naturally formed relatively steep slopes, which are difficult for workers to climb in actual sampling work. The current sampling devices for geological exploration are mainly aimed at conventional sampling terrains, not convenient for adapting to steep slope sampling.

[0042] As Figures 2 to 5As shown, the sampling support member 1 further includes two fan mounting cylinders 103 fixedly installed on the air suction mounting ring 101, and the two fan mounting cylinders 103 are respectively communicated with the air suction mounting ring 101; electric fans 104 are respectively installed inside the two fan mounting cylinders 103; the electric fans 104 are used to push the air suction mounting ring 101 backward; the traction connection part 2 includes a traction steel sheet 201 fixedly installed on the air suction mounting ring 101; the traction steel sheet 201 is used to hang the air suction mounting ring 101; the air suction mounting ring 101 is a thin sheet structure; a grip 202 is fixedly installed on the traction steel sheet 201; a rubber sleeve is provided on the grip 202.

At the same time, with the cooperation of the traction steel sheet 201, the sampling support member 1 can be towed, and rapid sampling can be realized by fitting on the slope. At the same time, this structure uses the negative pressure back-pushing method, which is safer for the staff to use. There is no need to stand on the slope for sampling. At the same time, this structure is flexible and convenient to use. The flat traction steel sheet 201 can prevent the air suction mounting ring 101 from twisting, so that the air suction mounting ring 101 can be attached to the slope.

[0043] As Figures 4 to 7 shown, the horizontal control member 3 includes two rotation connection seats 301 fixedly installed on the air suction mounting ring 101 by bolts, and a rotating shaft 3011 is rotatably installed on the two rotation connection seats 301; a counterweight traction block 302 is fixedly installed on the rotating shaft 3011; the counterweight traction block 302 is used to horizontally tow the filling auxiliary member 4; the counterweight traction block 302 is made of lead; the filling auxiliary member 4 includes a filling connection shell 401 fixedly installed on the rotation connection seat 301; the filling connection shell 401 is perpendicular to the counterweight traction block 302; a through hole is provided at the bottom of the filling connection shell 401; a filling column 402 is sleeved inside the filling connection shell 401; the filling column 402 is used to be discharged from the bottom of the filling connection shell 401; the diameter of the rear end of the filling column 402 is smaller than that of the front end. By using the filling auxiliary member 4, under the traction of the horizontal control member 3, the filling auxiliary member 4 can be kept horizontal, so that the sampling leak-proof member 5 can sample horizontally, ensuring the sampling accuracy. At the same time, through the filling auxiliary member 4, it is convenient to fill the sampling drill hole, effectively reducing the collapse risk. At the same time, this structure can automatically fill, ensuring the protection effect of the slope after sampling by this structure. The structure control is simple and flexible. The filling column 402 can play a supporting role, and the counterweight traction block 302 can tow downward, driving the filling connection shell 401 to keep horizontal.

[0044] As Figure 7 and Figure 8As shown, the sampling leak prevention member 5 includes two propulsion hydraulic cylinders 501 fixedly installed on both sides of the filling connection shell 401. A drilling motor 502 is fixedly installed on the output shafts of the two propulsion hydraulic cylinders 501 through brackets; a rotating column 503 is fixedly installed on the output shaft of the propulsion hydraulic cylinder 501; the rotating column 503 is located inside the filling connection shell 401; the sampling leak prevention member 5 further includes a sampling cylinder 504 fixedly installed at the end of the rotating column 503; the end of the sampling cylinder 504 is a serrated structure; the sampling cylinder 504 is used for drilling and sampling; the sampling cylinder 504 is slidably inserted into the filling connection shell 401; the filling column 402 is located above the sampling cylinder 504; the sampling cylinder 504 is used to limit the filling column 402; the sampling cylinder 504 is used to take soil samples; by using the sampling leak prevention member 5, rapid sampling of the slope soil can be achieved, and the sampling effect of the sample can be guaranteed. This structure can compact and prevent leakage of loose samples, and can ensure the sample block effect. The sampling leak prevention member 5 used can also be used to propel the filling column 402, ensuring that it can be automatically propelled and inserted into the sampling hole after sampling is completed, guaranteeing the protection effect. This structure utilizes the sampling leak prevention member 5 to drive the sampling cylinder 504 to rotate under the drive of the drilling motor 502, and cooperate with the propulsion hydraulic cylinder 501 to propel the sampling cylinder 504 to feed to achieve soil sampling. Subsequently, the sampling cylinder 504 can be driven to retract by the propulsion hydraulic cylinder 501. At this time, when the sampling cylinder 504 does not block the filling column 402, under the action of its own weight, the filling column 402 can fall to the front side of the sampling cylinder 504. The sampling cylinder 504 can be driven by the propulsion hydraulic cylinder 501 to push the filling column 402 into the sampled hole to complete the filling work. At the same time, by making the diameter of the rear end of the filling column 402 smaller than that of the front end, when the sampling cylinder 504 pushes the filling column 402 to move, the filling column 402 can compress the soil inside the sampling cylinder 504, increase the density, prevent leakage, and ensure the integrity of the sample.

[0045] As Figure 4 、 Figures 9 to 12As shown, the positioning member 6 includes a positioning slider 601 slidably mounted on the air suction mounting ring 101; a positioning post 602 is fixedly mounted on the positioning slider 601; the end of the positioning post 602 is of a conical structure; a positioning piece 603 is fixedly mounted on the positioning slider 601; the positioning piece 603 is of an arc structure; a positioning spring 604 is fixedly mounted at the bottom of the positioning slider 601; the end of the positioning spring 604 is fixedly mounted on the air suction mounting ring 101; the positioning spring 604 is used to elastically support the positioning slider 601; the collapse detection member 7 includes a surface-attached rubber pad 701 fixedly mounted on the side of the air suction mounting ring 101; the surface-attached rubber pad 701 is of a rubber hollow structure; a circle of positioning pieces 603 is fixedly mounted on the outside of the surface-attached rubber pad 701; a diversion pipe 702 is fixedly mounted on the side of the surface-attached rubber pad 701, and the diversion pipe 702 passes through the air suction mounting ring 101; a detection connection pipe 703 is fixedly mounted on the diversion pipe 702; two ventilation holes are provided at the end of the detection connection pipe 703; pure water is filled inside the surface-attached rubber pad 701; the collapse detection member 7 further includes a sliding connection piston 704 slidably sleeved on the detection connection pipe 703; a rubber ring is provided on the outside of the sliding connection piston 704; a micro switch 705 is fixedly mounted inside the detection connection pipe 703; the end of the micro switch 705 is located on the side of the sliding connection piston 704, and the micro switch 705 is electrically connected to two alarm lights 102; a compression tension spring 706 is sleeved on the detection connection pipe 703; the end of the compression tension spring 706 is connected inside the detection connection pipe 703; the other end of the compression tension spring 706 is fixedly mounted on the side of the sliding connection piston 704. By using the collapse detection member 7, it is possible to automatically detect the slope stability by using hydraulic pressure, and give a prompt alarm in time when accidents such as landslides and collapses occur on the slope. It can be attached to the soil surface to ensure the sampling stability. At the same time, it also prompts the staff to avoid the collapse detection member 7 from detecting in a suspended state. At the same time, this structure can also ensure the detection quality and improve the stability by using the positioning member 6 without the need for manual climbing on the slope. Observation can be made at the bottom of the slope. If the slope collapses or landslides, at this time, the soil attached to the surface-attached rubber pad 701 is displaced, and the degree of extrusion of the corresponding surface-attached rubber pad 701 changes, that is, to prevent sampling when the surface-attached rubber pad 701 is not attached to the soil, which affects the stability. By pushing the sliding connection piston 704 to separate from the micro switch 705 through the compression tension spring 706, the alarm light 102 can be controlled to light up for prompt, and the positioning member 6 is used to insert into the soil to improve the stability.

[0046] The working principle provided by the present invention is as follows. First, this structure is mainly used for steep slopes. When the perpendicularity of some positions of the steep slope is less than 90 degrees, it is impossible to fit the surface by the veneer rubber pad 701, and the sampling point needs to be changed. Subsequently, the principle of judging the stability of slope sampling by detecting the fitting degree of the veneer rubber pad 701 is described. Hold the handle 202, and the traction steel sheet 201 can be used to traction the suction installation ring 101 and place it on the slope surface. Lower the suction installation ring 101. The flat traction steel sheet 201 can fit on the edge of the slope top, and the flat traction steel sheet 201 can reduce the torsional amplitude of the suction installation ring 101, so that the suction installation ring 101 is attached to the slope surface. The weight traction block 302 can be used for downward traction to drive the filling connection shell 401 to be horizontal. Driven by the drilling motor 502, the sampling cylinder 504 is driven to rotate, and the sampling cylinder 504 is advanced by the propulsion hydraulic cylinder 501 to achieve soil sampling. Subsequently, the sampling cylinder 504 can be retracted by driving the propulsion hydraulic cylinder 501. At this time, when the filling column 402 above the sampling cylinder 504 is not blocked by the sampling cylinder 504, under the action of its own weight, the filling column 402 can fall to the front side of the sampling cylinder 504. The sampling cylinder 504 can be driven by the propulsion hydraulic cylinder 501 to push the filling column 402 into the sampling hole to complete the filling work. At the same time, since the diameter of the rear end of the filling column 402 is smaller than that of the front end, when the sampling cylinder 504 pushes the filling column 402 to move, the filling column 402 can compress the soil inside the sampling cylinder 504 to increase the density and prevent leakage. The veneer rubber pad 701 is attached to the slope surface. At this time, under the action of the wind pressure of the electric blower 104, the positioning column 602 will also be inserted into the soil. If the slope collapses or landslides, at this time, the soil attached to the veneer rubber pad 701 is displaced, and the soil no longer presses the veneer rubber pad 701. Once the veneer rubber pad 701 is suspended, the extrusion force acting on the veneer rubber pad 701 changes greatly. The sliding connection piston 704 can be pushed by the extrusion spring 706 to separate from the micro switch 705, so as to control the alarm lamp 102 to light up for prompt. Similarly, when this structure shakes greatly, the positioning column 602 inserted in the soil also plays a role in increasing stability.
