Description

Technical Field

[0001] This invention belongs to the field of geological exploration technology, and in particular relates to a rapid sampler for geological exploration in mining. Background Technology

[0002] In mining and geological exploration, it is necessary to analyze many characteristics of ore, such as composition and grade. Rapid samplers can obtain ore samples in a short time. Compared with large-scale excavation sampling, rapid samplers usually only require a small channel to obtain samples. In small-scale underground metal mines, if extensive sampling methods are used, it may damage the stability of the mine shaft. Rapid samplers can obtain samples with relatively small intrusion, minimizing damage to the original structure of the ore body, reducing safety risks, and also facilitating the subsequent mining of the ore body. For example, a rapid sampler for mining and geological exploration is proposed in patent publication number CN115791266A.

[0003] When using a rapid sampler to place ore samples, operators typically arrange the samples in an orderly manner to ensure accuracy of ore sample testing, facilitate information traceability and management, and improve the efficiency of researchers. However, due to the fast pace of the sampling process and the lack of experience among some new employees, the samples may become disorganized. When ore samples are placed in a disorganized manner, sample confusion can easily occur during operations such as component analysis and grade identification. For example, when testing the copper content in ore, if a sample with low copper content is mistakenly analyzed as a high-copper-content sample, incorrect copper grade data will be obtained. This will lead to an incorrect assessment of ore quality, which in turn will affect the decision-making process of the entire mining and beneficiation process.

[0004] To address these issues, a rapid sampler for mining and geological exploration is proposed. Summary of the Invention

[0036] The feeding assembly 31 is installed 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 feeding assembly 31 includes a support frame 311 fixedly connected to the upper side wall of the lifting plate 7.

[0037] Analysis component 44, located on the upper side wall of lifting plate 7, is used to analyze the wear condition of cutting section 12.

[0039] Two positioning hydraulic cylinders 57 are fixedly connected to the lower side wall of the base plate 1. The moving end of the positioning hydraulic cylinder 57 is fixedly connected to the insert plate 58. Multiple pins 59 are fixedly connected to the lower side wall of the insert plate 58, which improves the stability of the sampling device placement.

[0040] A horizontal plate 60 is fixedly connected to the left side wall of the base plate 1, and a small electric push rod 61 is fixedly connected to the lower side wall of the horizontal plate 60. A friction block 62 is fixedly connected to the moving end of the small electric push rod 61, which improves the stability of the placement ring 211.

[0041] The operating principle of this invention is explained as follows: The sampler is moved to the designated sampling position. Then, the operator controls the positioning hydraulic cylinders 57 on both sides via the control console 4. The positioning hydraulic cylinders 57 drive the insert plate 58 and the pin 59 downwards, causing the pin 59 to insert into the ground, thus fixing the base plate 1. Next, the operator uses a snap-fit ​​mechanism to fix the drive rod 10 below the rotating plate 9 (the snap-fit ​​mechanism is a slot and pin structure, which allows the drive rod 10 to be quickly assembled below the rotating plate 9, and the drive rod 10 can be connected to an extension rod via the snap-fit ​​mechanism according to usage requirements, thereby sampling ores at different depths). Then, the operator controls the screw via the control console 4. The thread lifting mechanism 6 operates (the thread lifting mechanism 6 consists of a threaded rod and a threaded cylinder; the threaded rod is rotated by a power source, which controls the lifting of the threaded cylinder, thereby controlling the up-and-down movement of the lifting plate 7). The thread lifting mechanism 6 drives the lifting plate 7 to move downwards. The lifting plate 7 drives the rotary motor 8, the drive rod 10, and the sampling cylinder 11 to move downwards together. During the downward movement, the sampling cylinder 11 and the drive rod 10 pass through the insertion port 26 on the surface of the placement ring 211 and the hole avoided by the bottom plate 1. During the downward movement of the sampling cylinder 11, the rotary motor 8 drives the rotating plate 9, the drive rod 10, and the sampling cylinder 11 to rotate together, thereby allowing the cutting part 12 to cut the ore below. The stone is cut and sampled. The cut sample material is stored in the sampling cylinder 11 (the sampling cylinder 11 has textured interior to increase the friction between the sample material and the sampling cylinder 11). When the sampling cylinder 11 descends to a certain depth, the PLC controller 5 controls the rotary motor 8 to stop working and controls the threaded lifting mechanism 6 to move the sampling cylinder 11 upward to a 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 adjusting motor 23 to work, which drives the rotating seat 24 to rotate. The rotating seat 24 drives the placement ring 211 to rotate via the crossbar 25. The placement ring 211 drives multiple collection cylinders 22 and multiple... A laser receiver 27 rotates clockwise together, and the first laser receiver 27 corresponding to the position of the collection cylinder 22 is controlled by the PLC controller 5. When multiple first laser receivers 27 are rotating, one of the first laser receivers 27 will receive the laser signal emitted by the first laser generator 28 first. After receiving the electrical signal, the 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 stop below the sampling cylinder 11 (the surfaces of multiple collection cylinders 22 will be marked with 1, 2, 3... in sequence, so that researchers can find the corresponding sample material according to the markings).

[0042] Next, the PLC controller 5 controls the rotary motor 8 to operate, and also controls the second laser generator 39 and the second laser receiver 40 to operate. As the rotary motor 8 drives the rotating plate 9 to rotate, it also drives the second laser receiver 40 to rotate. During this rotation, the second laser receiver 40 receives laser signals emitted from the second laser generator 39. Upon receiving this laser signal, the second laser receiver 40, through the PLC controller 5, controls the rotary motor 8 to stop operating and controls the horizontal electric push rod 34 to operate. The electric push rod 34 moves the horizontal tube 35 and the air vent 36 to the left to a set position, so that the air vent 36 is inserted into the slot 38 and fits against the inner wall of the slot 38. Then, the PLC controller 5 controls the first electromagnetic block 42 to de-energize and lose its magnetic force, and controls the second electromagnetic block 43 to energize and generate magnetic force. The second electromagnetic block 43 attracts the magnetic baffle 41 to work, causing the magnetic baffle 41 to rotate counterclockwise to a 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 pump external gas through the air vent 32. The first electromagnetic check valve 33, horizontal pipe 35, and air outlet hood 36 deliver the sample to the air delivery chamber 37, and then through the air delivery chamber 37, the sample is delivered to the sampling cylinder 11. This increases the air pressure above the sample in the sampling cylinder 11. Driven by the air pressure, the lower end of the sample extends out of the sampling cylinder 11 and inserts into the collection cylinder 22. Once the lower end of the sample contacts the bottom wall of the sampling cylinder 11, the sample will stop moving downwards, causing the air pressure inside the sampling cylinder 11 to continuously increase. The PLC controller 5 detects through the air pressure sensor 63 that the air pressure inside the sampling cylinder 11 exceeds the set value. When the threshold (200kPa) is reached, the PLC controller 5 will control the air pump 312 to stop 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. The electric cutting disc 30 will cut and separate the sample material between the sampling cylinder 11 and the collection cylinder 22. Then, the PLC controller 5 will use the electric cutting disc 30 to push the lower end of the cut sample material and control the regulating motor 23 to work. Based on the above principle, it will control the other collection cylinder 22 to continue collecting the sample 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. The PLC controller 5 will then control the air pump 312 to stop working and control the horizontal electric push rod 34 to drive the air vent 36 and slot 38 to separate. Then, 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 regulating motor 23 to rotate clockwise. When one of the first laser receivers 27 receives the laser signal from the first laser generator 28, the first laser receiver 27 will control the regulating motor 23 to stop working through the PLC controller 5 and control the threaded lifting mechanism 6 and the rotary motor 8 to repeat the previous work, controlling the sampling cylinder 11 to continue to move downward and continue to sample the ore.

[0044] When the sampling cylinder 11 is in the sampling process, if the cutting part 12 wears or deforms due to long-term operation, the resistance encountered by the sampling cylinder 11 during downward movement will be much greater than normal. 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 air pump 312 will then deliver external gas to the analysis chamber 441 through the bend pipe 442, increasing the air pressure in the space to the left of the piston block 46. Under the action of air pressure, the piston block 46 will move to the right by one-third of the distance. When this happens in three consecutive sampling processes, the piston block 46 will drive the conductive block. 47 continues to move to the right and comes into contact with 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 a position aligned with the CCD camera 56 through the threaded lifting mechanism 6. The CCD camera 56 will then 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 threaded lifting mechanism 6 through the PLC controller 5 to drive the sampling cylinder 11 to continue moving upward to the set position. Then, the PLC controller 5 will control the second electric slide... When the second electric slide rail 52 operates, it moves the collection cover 55 below the cutting section 12. Then, the PLC controller 5 controls multiple locking hydraulic cylinders 15 to move the fixing plate 16 and limit pins 17 upwards, releasing the fixing of the connecting frame 131. Under the elastic force of the top block 20 and the spring, the connecting frame 131 rotates clockwise, causing the cutting section 12 to disengage from the connecting groove 132. The cutting section 12, under gravity, falls into the collection cover 55. Then, the PLC controller 5 controls the second electric slide rail 52 to continue operating, moving the automatic clamp 54 below the collection cylinder 22 via the bending plate 53. The PLC controller 5 then... The sampling cylinder 11 is moved downward to a set position by the threaded lifting mechanism 6, so that the connecting frame 131 above the spare cutting part 12, which is held in the automatic clamp 54, is inserted into the connecting groove 132. Then, the automatic clamp 54 and the spare cutting part 12 are rotated to a set angle by the small motor under the bending plate 53, so that the connecting frame 131 is inserted into the set position in the connecting groove 132. During the rotation, the connecting frame 131 pushes the top block 20 to return to its original position. Then, the PLC controller 5 controls multiple positioning hydraulic cylinders 15 to work.
