[0047] See also Figures 9 and 10In the related art, the drilling sampling device for mining geology switches between a vertical sampling station and a horizontal sample withdrawal station, and then cooperates with the sample withdrawal of a horizontal thrust assembly and a locking sample withdrawal assembly. However, when the horizontal thrust assembly is connected to the locking sample withdrawal assembly, if the horizontal thrust assembly and the locking sample withdrawal assembly are not removable, the horizontal thrust assembly will affect the station conversion. If there is no connection between the two, the horizontal thrust assembly is directly used to push the connected locking sample withdrawal assembly, which will cause the locking sample withdrawal assembly to be unable to return to its position, and the locking sample withdrawal assembly will be fixed after returning to its position. Therefore, how to control the horizontal thrust assembly when it is connected to the locking sample withdrawal assembly, so that the horizontal thrust assembly can drive the locking sample withdrawal assembly to perform sample withdrawal work, and after sample withdrawal, the horizontal thrust assembly can drive the locking sample withdrawal assembly to return to its original position, and the horizontal thrust assembly and the locking sample withdrawal assembly can be automatically separated after returning to their positions, and the locking sample withdrawal assembly can be fixed after returning to their positions, has become a technical problem that needs to be solved.

The access tube unlocking block 790 pushes the locking end of the access tube locking member 780 to withdraw from the access tube locking tube 770. Then, the push rod 642 extends into the push rod access tube 720. Since the sample withdrawal plate 710 is abutted by the sample, the push rod 642 abuts against the push rod locking member 750. The inclined mouth 6423 at the end of the push rod 642 pushes the locking end of the push rod locking member 750 to pass over the push rod 642 and extend into the second clamping annular groove 6422.

[0051] Specifically, the working principle of the drilling sampling device for mining geology is as follows: when in use, the second motor 540 is started, the second motor 540 drives the second gear 550, the second gear 550 drives the first gear 530 through the gear meshing principle, the rotating cylinder 520 rotates with the first gear 530 in the mounting cylinder 413, the rotating cylinder 520 drives the sampling cylinder 510, and the sampling cylinder 510 breaks the mining geology through rotation to take samples, and then the first motor 330 is started, the first motor 330 drives the first screw 340 to rotate, and the first screw 340 drives the first screw 340 through the screw transmission principle. The movable frame 350 is driven to move along the slide bar 310, and the movable frame 350 drives the sampling barrel 510 to move downward and gradually enter the geology of the mine sampling, and the sample enters the sampling barrel 510. After the sampling is completed, the movable frame 350 drives the sampling barrel 510 to withdraw from the geology. After the sampling barrel 510 rises, the driving rod 440 is moved, and the driving rod 440 drives the mounting seat 450 to flip around the fixed seat 410 through the second ear seat 430. The mounting seat 450 drives the sampling barrel 510 to be converted from a vertical sampling station to a horizontal sampling station. Finally, the second motor 540 is started, and the second motor 540 is driven to rotate around the fixed seat 410. The second motor 540 drives the rotating cylinder 520 to rotate, adjusts the positioning hole 523 on the positioning sealing plate 522 and the horizontal thrust assembly 600 to be aligned, so that the horizontal thrust assembly 600 can pass through the positioning hole 523, starts the third motor 620, and the third motor 620 drives the second screw 630 to rotate. The second screw 630 drives the push plate 641 through the principle of thread transmission. The push rod 642 of the push plate 641 slides out along the end of the connecting frame 610. After the push rod 642 slides out of the connecting frame 610, it passes through the positioning hole 523 and is connected to the locking sample withdrawal assembly 700. 642 continues to push the locking sample withdrawal component 700, and the locking sample withdrawal component 700 withdraws the sample in the sampling tube 510 from the sampling tube 510. The operator receives the sample at the port of the sampling tube 510 for conducting sample surveys of mine geology. By switching between the vertical sampling station and the horizontal sample withdrawal station, and coordinating the sample withdrawal of the horizontal thrust component 600 and the locking sample withdrawal component 700, the sampling tube 510 does not need to be removed during the sample withdrawal process. The sampling process is simple, with less manpower assistance, which is convenient for saving time required for multiple samplings and reducing manpower consumption.

[0052] When the push rod 642 is connected to the locking sample withdrawal assembly 700, the push rod 642 passes through the positioning hole 523 and first abuts against the access tube unlocking block 790. The sloped opening 6423 at the end of the push rod 642 cooperates with the V-shaped slope 792 to push the second unlocking block 791. The second unlocking block 791 drives the connecting block 781. The second movable rod 783 slides along the second fixed plate 784. The connecting block 781 drives the second compression spring 785 to be compressed and the elastic force increases. The access tube locking block 782 moves with the connecting block 781. The fourth slope of the access tube locking block 782 withdraws from the access tube locking tube 770, and the locking of the fourth slope of the access tube locking block 782 on the first clamping annular groove 730 on the push rod access tube 720 is released. This facilitates the push rod access tube 720 to withdraw from the access tube locking tube 770.Afterwards, the push rod 642 extends into the push rod receiving tube 720. Since the sample withdrawal plate 710 is pressed against the sample, the push rod 642 presses against the push rod locking block 751. The sloped mouth 6423 at the end of the push rod 642 cooperates with the first slope to push the push rod locking block 751 to retract. The first movable rod 753 slides along the first fixed plate 754. The push rod locking block 751 drives the first compression spring 755 to be compressed and the elastic force increases. After the first slope of the push rod locking block 751 extends into the second clamping annular groove 6422, the first slope of the push rod locking block 751 locks the second clamping annular groove 6422, thereby locking the push rod. 642, to reduce the possibility of the push rod 642 coming out of the push rod access tube 720, the push rod 642 abuts against the sample withdrawal plate 710, and the sample withdrawal plate 710 pushes the sample out of the sampling tube 510. After the sample is withdrawn, the third motor 620 reverses and drives the push rod 642 to be retracted into the connecting frame 610. Since the push rod 642 is locked by the push rod locking block 751, the push rod 642 drives the push rod access tube 720, and the sample withdrawal plate 710 moves with the push rod access tube 720. As the sample withdrawal plate 710 is retracted, the push rod unlocking block 760 is gradually inserted into the push rod locking block 751, and the push rod unlocking block 760 pushes The first slope of the push rod locking block 751 is withdrawn from the push rod access tube 720, releasing the lock of the push rod locking block 751 on the push rod 642. At this time, the push rod access tube 720 is also inserted into the access tube locking tube 770. Since the lock of the push rod locking block 751 on the push rod 642 is released, the push rod 642 continues to be recovered, and the push rod access tube 720 stays in the access tube locking tube 770. After the push rod 642 leaves the access tube unlocking block 790, the connecting block 781, the access tube locking block 782 and the second unlocking block 791 return to their original positions under the elastic force of the second compression spring 785, and the access tube The locking block 782 locks the first clamping annular groove 730 on the push rod access tube 720, so as to achieve the purpose of locking the push rod access tube 720, and further achieves the purpose of controlling the horizontal thrust assembly 600 to drive the locked sample withdrawal assembly 700 to withdraw the sample when it is connected to the locked sample withdrawal assembly 700, and after the sample is withdrawn, the horizontal thrust assembly 600 can drive the locked sample withdrawal assembly 700 to return to its original position, and the horizontal thrust assembly 600 and the locked sample withdrawal assembly 700 can be automatically separated after returning to their original position, and the locked sample withdrawal assembly 700 can be fixed after returning to their original position.
