Description

Technical Field

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

[0002] During the processes of mining and geological exploration, it is necessary to analyze various characteristics of ores, such as composition and grade. A rapid sampler can obtain ore samples within a relatively short time. Compared with large-scale excavation sampling, a rapid sampler usually only requires a relatively small channel to obtain samples. In small underground metal mines, if an extensive sampling method is adopted, it may damage the stability of the mine tunnel. However, a rapid sampler can obtain samples in a relatively less invasive manner, minimizing the damage to the original structure of the ore body, reducing safety risks, and also being beneficial to the subsequent mining of the ore body. For example, a rapid sampler for geological exploration in mining proposed in Patent Publication No. CN115791266A.

[0003] When placing the ore sampling materials using a rapid sampler, in order to ensure the accuracy of ore sampling material detection, facilitate information traceability and management, and improve the detection efficiency of researchers, usually, the sampling materials taken out by the sampler are placed in an orderly manner by operators. Due to the relatively fast working rhythm during the sampling process and the lack of experience of some new employees, the placement of the sampling materials may be chaotic. When the ore sampling materials are placed chaotically, it is very easy to have the situation of sample confusion during operations such as component detection and grade identification. For example, when detecting the copper content in the ore, if the sample with a low copper content is wrongly regarded as a high-content sample for analysis, wrong copper grade data will be obtained, which will lead to an incorrect assessment of the ore quality and further affect the decision-making of the entire mining and ore dressing processes.

[0036] The material pushing component 31 is arranged on the upper side wall of the lifting plate 7 to assist in the discharge of the sampled material inside the sampling cylinder 11. The material pushing component 31 includes a support frame 311 fixedly connected to the upper side wall of the lifting plate 7.

After a certain amount of ore sampled material is extracted from the ore vein by the sampler, when the ore sampled material is placed in the collection cylinder 22 for storage, it is not necessary for the operator to knock on the sampling cylinder 11 to separate the sampled material from the sampler, which improves the convenience of use for the operator;

[0037] The analysis component 44 is arranged on the upper side wall of the lifting plate 7 and is used to analyze the wear condition of the cutting part 12. The analysis component 44 includes an analysis box 441 fixedly connected to the upper side wall of the lifting plate 7.

[0039] The lower side wall of the bottom plate 1 is fixedly connected with two positioning hydraulic cylinders 57. The moving end of the positioning hydraulic cylinder 57 is fixedly connected with a plug board 58, and the lower side wall of the plug board 58 is fixedly connected with a plurality of nails 59, which improves the stability of the placement of the sampling device.

[0041] The operating principle of the present invention is described as follows: Move the sampler to the designated sampling position. Then, the operator controls the operation of the positioning hydraulic cylinders 57 on both sides through the console 4. The positioning hydraulic cylinders 57 drive the plug board 58 and the plug pins 59 to move downward together, so that the plug pins 59 are inserted into the ground, and thus the bottom plate 1 can be fixed well. Then, the operator fixes the driving rod 10 below the rotating plate 9 through the clamping mechanism (the clamping mechanism is a structure of a clamping groove and a clamping pin, which can quickly assemble the driving rod 10 below the rotating plate 9, and the driving rod 10 can be connected with an extension rod through the clamping mechanism according to the use requirements, so as to sample ores at different depths). Then, the operator controls the operation of the screw lifting mechanism 6 through the console 4 (the screw lifting mechanism 6 is composed of a screw rod and a screw barrel. By controlling the rotation of the screw rod through a power source, the lifting of the screw barrel can be controlled, so as to control the up and down movement of the lifting plate 7). The screw lifting mechanism 6 drives the lifting plate 7 to move downward. The lifting plate 7 drives the rotating motor 8, the driving rod 10 and the sampling cylinder 11 to move downward together. The sampling cylinder 11 and the driving rod 10 will pass through the insertion openings 26 on the surface of the placement ring 211 and the holes on the bottom plate 1 during the downward movement. During the downward movement of the sampling cylinder 11, the rotating motor 8 drives the rotating plate 9, the driving rod 10 and the sampling cylinder 11 to rotate together, so that the ore below can be cut and sampled by the cutting part 12. The sampled material cut off will be stored in the sampling cylinder 11 (the inside of the sampling cylinder 11 is provided with lines to increase the friction between the sampled material and the sampling cylinder 11). When the sampling cylinder 11 descends to a certain depth, the PLC controller 5 will control the rotating motor 8 to stop working, and control the screw lifting mechanism 6 to drive the sampling cylinder 11 to move upward to the set position, so that the lower end of the sampling cylinder 11 is higher than the height of the collection cylinder 22. Then, the PLC controller 5 controls the regulating motor 23 to work. The regulating motor 23 drives the rotating seat 24 to rotate. The rotating seat 24 drives the placement ring 211 to rotate through the cross bar 25. The placement ring 211 drives a plurality of collection cylinders 22 and a plurality of first laser receivers 27 to rotate clockwise together, and the first laser receivers 27 corresponding to the positions of the collection cylinders 22 will be controlled to work by the PLC controller 5. When the plurality of first laser receivers 27 are rotating, one of the first laser receivers 27 will first receive the laser signal emitted by the first laser generator 28. After receiving this electrical signal, this first laser receiver 27 will control the regulating motor 23 to stop working. At this time, the collection cylinder 22 located at the rear will stay below the sampling cylinder 11 (the surfaces of the plurality of collection cylinders 22 are respectively marked with 1, 2, 3... in sequence. Subsequently, researchers can find the sampled materials in the corresponding sequence according to the marks);

[0042] Next, the PLC controller 5 controls the rotation motor 8 to work and controls the second laser generator 39 and the second laser receiver 40 to work. During the process of driving the turntable 9 to rotate, the rotation motor 8 will drive the second laser receiver 40 to rotate together. During the rotation process, the second laser receiver 40 will receive the laser signal emitted by the second laser generator 39. When the second laser receiver 40 receives this laser signal, the second laser receiver 40 will control the rotation motor 8 to stop working through the PLC controller 5 and control the horizontal electric push rod 34 to work. The horizontal electric push rod 34 will drive the horizontal pipe 35 and the air outlet cover 36 to move leftward to the set position, so that the air outlet cover 36 is inserted into the slot 38 and fits with the inner wall of the slot 38. Then, the PLC controller 5 controls the first electromagnet 42 to cut off the power and lose magnetism, and controls the second electromagnet 43 to energize and generate magnetism. The second electromagnet 43 will attract the magnetic baffle 41 to work, so that the magnetic baffle 41 rotates counterclockwise to the horizontal position. Then, the PLC controller 5 controls the air pump 312 and the first electromagnetic check valve 33 to work. The air pump 312 will transport the external gas through the air outlet pipe 32, the first electromagnetic check valve 33, the horizontal pipe 35 and the air outlet cover 36 to the air supply chamber 37, and then transport it to the sampling cylinder 11 through the air supply chamber 37, increasing the air pressure above the sampling material in the sampling cylinder 11. The lower end of the sampling material will extend out of the sampling cylinder 11 and be inserted into the collection cylinder 22 under the push of the air pressure. When the lower end of the sampling material contacts the bottom wall of the sampling cylinder 11, the sampling material will not continue to move downward, resulting in a continuous increase in the air pressure inside the sampling cylinder 11. When the PLC controller 5 detects through the air pressure sensor 63 that the air pressure inside the sampling cylinder 11 exceeds the set threshold (200 kPa), the PLC controller 5 will control the air pump 312 to pause working and control the first electric slide rail 29 and the electric cutting disc 30 to work. The first electric slide rail 29 will drive the electric cutting disc 30 to move forward, and use the electric cutting disc 30 to cut and separate the sampling material between the sampling cylinder 11 and the collection cylinder 22. Then, the PLC controller 5 uses the electric cutting disc 30 to push the lower end of the cut sampling material and controls the adjustment motor 23 to work. Referring to the above principle, it will control another collection cylinder 22 to continue collecting the sampling material;

[0043] After the sampling material inside the sampling cylinder 11 is collected, the PLC controller 5 will detect through the air pressure sensor 63 that the air pressure inside the sampling cylinder 11 is close to the atmospheric pressure. Then the PLC controller 5 will control the air pump 312 to stop working, and control the horizontal electric push rod 34 to drive the air outlet cover 36 to separate from the slot 38. Next, the PLC controller 5 will control the first laser receiver 27 at the position corresponding to the insertion port 26 to work, and control the adjustment motor 23 to rotate clockwise. When one of the first laser receivers 27 receives the laser signal emitted by the first laser generator 28, this first laser receiver 27 will control the adjustment motor 23 to stop working through the PLC controller 5, and control the screw lifting mechanism 6 and the rotation motor 8 to repeat the previous work, controlling the sampling cylinder 11 to continue moving downward to continue sampling the ore;

[0044] When the sampling cylinder 11 is in the process of sampling, after the cutting part 12 is worn or deformed due to long-term work, the resistance encountered by the sampling cylinder 11 during downward movement will far exceed the normal state. When the PLC controller 5 detects this situation through the pressure sensor between the rotary motor 8 and the rotating plate 9, the PLC controller 5 will control the air pump 312 and the second solenoid valve check valve 45 to work simultaneously for 0.5 seconds. The control air pump 312 will transport external gas into the analysis box 441 through the elbow pipe 442, increasing the air pressure in the left space of the piston block 46. Under the action of the air pressure, the piston block 46 will move one-third of the distance to the right. When this situation occurs three consecutive times during the sampling process, the piston block 46 will drive the conductive block 47 to continuously move to the right and contact the conductive plate 48. The conductive block 47 is electrically connected to the external power supply, and the conductive plate 48 is electrically connected to the PLC controller 5. When the PLC controller 5 receives the electrical signal transmitted from the conductive plate 48, the PLC controller 5 will drive the sampling cylinder 11 to move to a position aligned with the CCD camera 56 through the screw lifting mechanism 6, and use the CCD camera 56 to detect the wear degree of the cutting part 12 below the sampling cylinder 11. When the CCD camera 56 detects that the cutting part 12 is severely worn, the CCD camera 56 will control the screw lifting mechanism 6 to drive the sampling cylinder 11 to continue moving upward to a set position through the PLC controller 5. Then the PLC controller 5 controls the second electric slide rail 52 to work, and the second electric slide rail 52 will drive the collection cover 55 to move below the cutting part 12. Then the PLC controller 5 controls a plurality of clamping hydraulic cylinders 15 to drive the fixing plate 16 and the limit pin 17 to move upward together, thereby releasing the fixation of the connecting frame 131. Under the elastic force of the top block 20 and the spring, the connecting frame 131 will drive the cutting part 12 to rotate clockwise, causing the connecting frame 131 to disengage from the connecting groove 132. Under the action of gravity, the cutting part 12 will fall into the collection cover 55 for placement. Then the PLC controller 5 controls the second electric slide rail 52 to continue working, so that the second electric slide rail 52 drives the automatic fixture 54 to move below the collection cylinder 22 through the bent plate 53. Then the PLC controller 5 controls the sampling cylinder 11 to move downward to a set position through the screw lifting mechanism 6, so that the connecting frame 131 above the spare cutting part 12 clamped inside the automatic fixture 54 is inserted into the connecting groove 132. Then, through the small motor below the bent plate 53, the automatic fixture 54 and the spare cutting part 12 are controlled to rotate to a set angle simultaneously, so that the connecting frame 131 rotates and inserts into the set position in the connecting groove 132. During the rotation of the connecting frame 131, it will push the top block 20 back to its original position. Then the PLC controller 5 controls a plurality of clamping hydraulic cylinders 15 to work, and the clamping hydraulic cylinders 15 will drive the limit pin 17 to insert into the limit hole 18 through the fixing plate 16, thus fixing the new cutting part 12 well and ensuring the working efficiency of the rapid sampler.
