Description

Technical Field

[0001] The invention relates to the technical field of mineral exploration sampling, in particular to a sampling device used for geological and mineral exploration. Background Art

[0002] Sampling in geological and mineral exploration is an important part of geological prospecting. It involves collecting samples from soil layers, ore bodies, rocks, etc. The purpose of geological and mineral exploration is to observe and study rock structure, texture, mineral composition and its symbiotic combination, study the metamorphism and alteration of minerals, and determine the names of rocks and minerals in order to study the quality, physical and chemical properties of minerals. The core purpose of sampling in geological and mineral exploration is to provide data basis for evaluating ore deposits, calculating reserves, and solving problems in geology, mining, beneficiation and comprehensive utilization of minerals.

[0003] At present, when exploring and sampling rock minerals, a tubular drill is used to drill a hole downward on the rock surface, and a sampling tube is installed on the tubular drill. When the tubular drill reaches a certain depth, a rock sample core will be stored in the middle of the sampling tube. After the sampling tube is removed from the rock, the rock sample core in the sampling tube is taken out to complete the sampling work. However, friction will occur between the rock sample core and the sampling tube, and the rock sample core is difficult to be removed from the sampling tube. At this time, the staff needs to continuously knock on the sampling tube to generate vibration so that the rock sample core can slide out of the sampling tube. However, the vibration caused by the knocking causes the rock sample core to be impacted, causing the entire rock sample core to break or shatter, destroying the integrity of the rock sample core.

[0004] On the other hand, the patent with the search announcement number CN115931437B discloses a portable sampling device for geological and mineral exploration, which improves the working stability of the sampling tube and the drill rod, prevents the drill rod from breaking, and ensures the efficient removal of the ore sample. However, when sampling rock minerals, it is difficult for the above device to horizontally cut the rock sample core. At present, after the tubular drill bit of the exploration sampling device drills the rock from top to bottom and reaches the specified depth, the bottom end of the rock sample core column is still connected to the rock ore body, which makes it difficult for the rock sample core to follow the sampling tube to move out. At this time, it is generally solved in two ways. One is to make the tubular drill bit continue to drill downward and completely penetrate the rock ore body, but this method increases the workload of exploration sampling and affects the progress of exploration sampling. The second is to vibrate the rock sample core to break the rock sample core and the rock ore body, but this method causes the rock sample core to break into multiple sections, destroying the integrity of the rock sample core and affecting the later staff's exploration of the rock sample core. To this end, we provide a sampling device for geological and mineral exploration to solve the above problems. Summary of the invention

The two slide bars 404 are slidably connected to the limit rod three 314. The control motor three 313 drives the limit rod three 314 to rotate. The rotation of the limit rod three 314 drives the rotating tube 403 to rotate through the two slide bars 404.

By setting the limiting rod 408, the stability of the circular slideway 406 when moving up and down is increased.

[0044] See also Figure 8 and Fig.14 Four cutting mechanisms 5 are arranged inside the rotating cylinder 409. The cutting mechanism 5 includes a sleeve 501, which is fixed to the inner wall of the rotating cylinder 409. The sleeve 501 is slidably connected to the sampling cylinder 2.

[0045] See also Figure 8 , Fig.11 and Fig.12 The cutting mechanism 5 also includes a collar 507 fixed on the inner wall of the slip ring 407, the collar 507 is sleeved on the outer surface of the deflection column 505, a sliding column 508 is fixed on the inner wall of the collar 507, and the sliding column 508 is slidably connected to the inner wall of the oblique arc groove 506.

When the slip ring 407 drives the collar 507 to move downward, the sliding column 508 on the inner wall of the collar 507 will slide in the oblique arc groove 506, causing the deflection column 505 to deflect. The deflection of the deflection column 505 will drive the arc block 503 to deflect through the long rod 502. After the sliding column 508 slides to the bottom end of the oblique arc groove 506, the cutting heads 504 on the four arc blocks 503 will contact each other.

When the four arc blocks 503 are close to each other, the arc blocks 503 are located in the through grooves 8. At this time, the arc blocks 503 can move in the through grooves 8 to avoid interference between the arc blocks 503 and the sampling tube 2 when they move upward. Through the setting of the retention grooves 7, when the sliding column 508 slides to the top of the oblique arc groove 506, the four arc blocks 503 are respectively located in the four retention grooves 7 to avoid interference between the arc blocks 503 and the rock sample core when the sampling drill bit 6 is drilling downward.

[0047] Working principle: When drilling and sampling is performed, the control motor 302 drives the threaded rod 303 to rotate. The threaded rod 303 rotates through the threaded block 306 to drive the movable plate 305 to move downward. The annular slideway 308 at the bottom of the movable plate 305 will drive the sampling tube 2 to move downward through the four sliders 315, and the control motor 313 drives the limit rod 314 to rotate. The limit rod 314 rotates through the two slide bars 404 to drive the rotating tube 403 to rotate. The rotating tube 403 rotates through the belt and the pulley to drive the rotating tube 409 to rotate. The rotation of the rotating tube 409 will drive the sampling tube 2 to rotate through the four sleeves 501, so that the sampling tube 2 rotates and moves downward to drive the sampling drill bit 6 to drill the rock ore body.

[0048] After the sampling drill bit 6 reaches the specified depth, the motor 302 is controlled to stop so that the sampling drill bit 6 stops moving downward, and then the electric telescopic rod 405 is controlled to move the slip ring 407 downward through the annular slideway 406, so that the four collars 507 on the slip ring 407 move downward, and the sliding column 508 in the collar 507 will slide in the inclined arc groove 506 to deflect the deflection column 505. The deflection column 505 will drive the arc block 503 to rotate through the long rod 502, so that the four cutting heads 504 continue to approach the rock sample core, and the rotating cylinder 409 rotates to make the four sleeves 501 rotate around the rock sample core, so that the four cutting heads 504 cut the bottom end of the rock sample core to separate the rock sample core from the rock ore body. The mineral sampling process is convenient and fast, and the integrity of the rock sample core is protected by the sampling method of horizontally cutting and separating the rock sample core.

[0049] After the rock sample core is separated from the rock ore body, the control motor 2 311 is started to drive the threaded rod 2 312 to rotate, so that the threaded rod 2 312 rotates through the threaded tube 402 to drive the movable frame 401 to move upward, and the movable frame 401 will drive the four sleeves 501 to move upward through the rotating cylinder 409, so that the four arc blocks 503 support the rock sample core in the sampling tube 2 to move upward, and the four arc blocks 503 lift the rock sample core and move it out of the sampling tube 2, completing the separation of the rock sample core and the sampling tube 2, making it convenient for the staff to directly take the collected rock sample core, and effectively avoiding the problem of the entire rock sample core being broken or crushed due to the manual knocking separation method.

[0050] When the device is reset after sampling, the motor 1 302 is controlled to drive the threaded rod 1 303 to rotate so that the movable plate 305 moves upward, and the annular slideway 1 308 at the bottom of the movable plate 305 drives the sampling tube 2 to move upward through the four sliders 315. After the movable plate 305 moves to the top, the sampling tube 2 will move to the ground, and the motor 1 302 is stopped and the motor 2 311 is started, so that the motor 2 311 drives the movable frame 401 to move downward through the threaded rod 2 312 and the threaded tube 402, and the movable frame 401 will drive the four sleeves 50 1 moves downward, so that the bottom end of the sleeve 501 moves to the bottom end of the through slot 8, the motor 2 311 is stopped and the electric telescopic rod 405 is started, so that the electric telescopic rod 405 drives the slip ring 407 to move upward through the annular slideway 2 406, so that the slip ring 407 drives the sleeve ring 507 to move upward, so that the sliding column 508 in the sleeve ring 507 drives the deflection column 505 to deflect through the oblique arc groove 506, and the deflection column 505 deflects the arc block 503 through the long rod 502, so that the four arc blocks 503 are respectively located in the four retention grooves 7, and the reset is completed.
