[0026] Compared with the prior art, the above technical scheme of the present application has the following beneficial technical effects:

[0027] The driving device one is started to drive the lifting plate to descend, the driving device two is started to drive the sampling outer cylinder to rotate, and the sampling inner cylinder does not rotate, the sampling outer cylinder is drilled into the ground, and the sample enters the sampling inner cylinder, so that the sample is collected.

[0028] Meanwhile, the spray pipe sprays cooling water to the space between the sampling outer cylinder and the sampling inner cylinder through the spray head, so that the sampling outer cylinder and the sampling inner cylinder are cooled; when the sample is relatively soft, the conical rotating disc pulls the pull rope to descend, so that the amount of the pull rope in the winding reel is reduced; at this time, the pushing frame is pressed on the pull rope by the elasticity of the elastic member four, and with the reduction of the pull rope, the pushing frame moves to the pull rope, so as to interfere with the moving rack to drive the gear two to rotate, and then drive the rotating disc to rotate in the spray pipe, so as to reduce the blocking area in the spray pipe, so that the resistance received by the water flow in the spray pipe is reduced, and the water flow speed and the spraying amount are gradually increased, which also means that the depth of the sampling inner cylinder is gradually deeper; at this time, since the contact area between the sampling outer cylinder and the sampling inner cylinder and the underground soil is increased, the friction is increased, and the heat generated is more, so that the water consumption is gradually increased with the depth of the sampling outer cylinder and the sampling inner cylinder.

[0029] When the lifting plate drives the sampling outer cylinder and the sampling inner cylinder to descend, if it is only soft sample and the like, the lifting plate descends, at this time the electric take-up reel releases the lower pressing plate, the lower pressing plate descends under the pulling force of the elastic element two, but due to the limiting of the lifting block to the lower pressing plate and the friction force between the lifting block and the damping plate, the descending speed of the lower pressing plate is slower than that of the lifting plate, when the sampling outer cylinder and the sampling inner cylinder touch the hard sample, such as rock and the like, at this time the descending speed of the sampling outer cylinder and the sampling inner cylinder is reduced, thus the lower pressing plate catches up with the lifting plate and presses the piston shaft down, the piston shaft one extrudes the air in the inner cavity of the piston cylinder one to the piston cylinder two, drives the piston shaft two to retract into the piston cylinder two and separate from the rack block, at this time the rack block descends under the pulling force of the elastic element one, thus the rack block separates from the bottom plate at the bottom of the elastic element five, at this time the elasticity of the elastic element five retraction drives the movable rack to descend, makes the movable rack separate from the gear two, and then through the elasticity of the coil spring cylinder three, drives the spray pipe to reset, makes the coil spring cylinder three in the inner cavity of the spray pipe directly become vertical, reduces the resistance to the water flow in the spray pipe to the maximum extent, thus increases the water flow of the spray head to the highest state, thus realizes the method of gradually increasing the spraying amount with the depth when facing the soft soil sample and the like, and directly increases the spraying amount to the maximum extent when facing the hard sample, such as rock, thus realizes the dynamic adjustment of the spraying amount and saves the water.

[0030] When the sampling outer cylinder contacts the rock, the rack block descends and engages with the gear one, drives the gear one to reverse for a distance, thus drives the take-up reel to reverse, the take-up reel pulls the pull rope to move upward for a distance, winds a part of the pull rope in the take-up reel, thus pulls the conical rotating disc to move horizontally along the L groove, makes the conical rotating disc and the mounting part stagger, thus separates the soil and the like above the conical rotating disc and the mounting part from the rock and the like below, and with the descending of the sampling inner cylinder, makes the conical rotating disc gradually ascend along the L groove, finally before the sampling ends, the rock at the bottom of the conical rotating disc and the mounting part can compress the soil and the like sample above the conical rotating disc and the mounting part, thus realizes the separation of the soil and the like sample and the rock and the like sample, thus realizes the classification of the sample, and through the compression of the soil, makes the soil sample not easy to disperse when discharging from the sampling inner cylinder.

[0049] A plurality of detachable components such as detachable buckles are arranged on the pull rope 7, and when the sampling inner cylinder 12 is detached and the sample is taken out, the pull rope 7 is disconnected through the detachable components on the pull rope 7, so that the sampling inner cylinder 12 is taken down.

[0050] The sampling assembly comprises a sampling outer cylinder 11, a sampling inner cylinder 12 and a driving device two 38.

[0051] The driving device two 38 is mounted on the lifting plate 4, the sampling outer cylinder 11 is connected with the output shaft of the driving device two 38, the sampling inner cylinder 12 is mounted on the lifting plate 4 and is sleeved in the sampling outer cylinder 11, the sampling outer cylinder 11 and the sampling inner cylinder 12 are detachably connected, and the separation mechanism is mounted in the sampling inner cylinder 12.

[0052] The driving device two 38 is in driving connection with the sampling outer cylinder 11 through a transmission belt, or a connection mode such as a gear can be adopted; in the prior art, after the sample collection in the sampling inner cylinder 12 is completed, the sampling outer cylinder 11 and the sampling inner cylinder 12 are detached, and then the sample collected in the inner cavity of the sampling inner cylinder 12 is poured out.

[0053] The detection assembly comprises a piston cylinder one 15, a piston shaft one 16, a connecting pipe 17, a piston cylinder two 19 and a piston shaft two 20.

[0054] Piston cylinder one 15 is installed on lifting plate 4, piston shaft one 16 is elastically connected in piston cylinder one 15, two ends of connecting pipe 17 are communicated with piston cylinder one 15 and piston cylinder two 19 respectively, piston shaft two 20 is elastically connected in piston cylinder two 19, piston shaft two 20 is inserted into limiting component for limiting lifting of limiting component.

[0055] When the descending speed of lifting plate 4 slows down, it represents that sampling outer cylinder 11 contacts with hard rock at this time, the descending speed of lifting plate 4 will slow down, at this time, piston shaft one 16 is caught up by lower pressing plate 25, so that lower pressing plate 25 is lowered and piston shaft one 16 is pressed.

[0056] Limiting component includes elastic member one 21, rack block 22 and gear one 23.

[0057] Fixed end of elastic member one 21 is installed on installation bin 2, movable end of elastic member one 21 is installed rack block 22, and bottom end of elastic member one 21 penetrates installation bin 2 and is located on the moving path of lifting plate 4, rack block 22 is inserted by the transverse end of detection component, gear one 23 is installed on rope winding disc 6 and rotates with rope winding disc 6, rack block 22 is lowered and engaged with gear one 23.

[0058] Elastic member one 21 and elastic member five 35 are composed of spring one and round rod, the top end of round rod of elastic member one 21 is connected with rack block 22, and the bottom end of round rod of elastic member one 21 is located on the moving path of lifting plate 4, the top end of round rod of elastic member five 35 is connected with moving rack 36, and the bottom end of round rod of elastic member five 35 is connected with bottom plate 37.

[0059] Elastic member two 24, elastic member three 26 and elastic member four 33 are composed of spring two and telescopic rod.

[0060] Damping component includes elastic member two 24, lower pressing plate 25, elastic member three 26, lifting block 27, damping plate 28 and electric rope winding disc 39.

[0061] Two ends of elastic member two 24 are connected with installation frame 1 and lower pressing plate 25 respectively, lower pressing plate 25 is located above the component end of detection component, two ends of elastic member three 26 are connected with installation frame 1 and lifting block 27 respectively, damping plate 28 is installed on installation frame 1, lifting block 27 is attached to damping plate 28, electric rope winding disc 39 is installed on installation frame 1 and is used for pulling lower pressing plate 25 to rise and reset.

[0062] Through the friction force of lifting block 27 and damping plate 28, the descending speed of lifting block 27 is reduced, and then the descending speed of lower pressing plate 25 is reduced, when sampling inner cylinder 12 finishes sampling and is ready to rise and unload, electric rope winding disc 39 is started to pull lower pressing plate 25 to rise, but lower pressing plate 25 is pressed above lifting block 27, so that lower pressing plate 25 is not affected by resistance when rising.

[0063] The electric take-up reel 39 is composed of a motor, a take-up reel and a rope. The motor is installed outside the mounting frame 1, the take-up reel is installed on the output shaft of the motor, and the mounting part 9 pulls the pusher 25 back to the original position through the rope.

[0064] The liquid outlet assembly includes a spray pipe 29, a coil spring cylinder 30, a rotating disc 31, a gear 32 and a spray head 40.

[0065] The spray pipe 29 is installed in the mounting chamber 2, and the bottom of the spray pipe 29 is provided with the spray head 40 for spraying water to the sampling assembly. The coil spring cylinder 30 is installed outside the spray pipe 29. The rotating shaft of the coil spring cylinder 30 penetrates the spray pipe 29 and is connected with the rotating disc 31. The rotating disc 31 penetrates the spray pipe 29 and is connected with the gear 32.

[0066] A servo motor is installed in the inner cavity of the mounting chamber 2. The output shaft of the servo motor is connected with the rotating shaft of the coil spring cylinder 30. When the sampling outer cylinder 11 and the sampling inner cylinder 12 are lowered from the soft sample to the hard sample, the rotating disc 31 is in the vertical state due to the lowering of the moving rack 36. Therefore, when the sampling outer cylinder 11 and the sampling inner cylinder 12 are lifted after the sampling is completed, the rotating shaft of the coil spring cylinder 30 can be rotated by the servo motor.

[0067] If the sampling inner cylinder 12 encounters a hard sample when it is just lowered, the pull rope 7 in the inner cavity of the take-up reel 6 is not discharged much, and therefore the pusher 34 does not move much distance. When it is reset, the rotating disc 31 can be reversed by the servo motor to reset by half a turn. If the sampling inner cylinder 12 encounters a hard sample when it is lowered by half, the rotating disc 31 is reversed by the servo motor by one fourth of a turn. The remaining reset is achieved by separating the rack block 22 from the gear 1 23, and then the take-up reel 6 is reversed to reset by the coil spring cylinder 1 5. The take-up reel 6 is reversed to reset the pull rope 7, and the pull rope 7 is rewound in the take-up reel 6, thereby moving the pusher 34 to the direction of the elastic member 4 33. At this time, the moving rack 36 is re-engaged with the gear 2 32 due to the upward pushing of the elastic member 1 21, thereby driving the gear 2 32 to continue rotating to reset.

[0068] The connecting pipe 17 and the spray pipe 29 are both telescopic pipes. The bottom end of the spray pipe 29 is fixed on the lifting plate 4, and the spray head 40 is directed towards the gap between the sampling outer cylinder 1 1 and the sampling inner cylinder 12. Alternatively, the spray head 40 can be installed on the top of the gap between the sampling outer cylinder 1 1 and the sampling inner cylinder 12.

[0069] The follow-up assembly includes the elastic member 4 33, the pusher 34 and the engagement unit.

[0070] The two ends of the elastic member 4 33 are respectively connected with the mounting chamber 2 and the pusher 34. The pusher 34 abuts against the pull rope 7 in the take-up reel 6. The engagement unit is installed on the pusher 34.

[0071] The engagement unit includes the elastic member 5 35, the moving rack 36 and the bottom plate 37.

[0072] The fixed end of the elastic piece five 35 is connected with the pushing frame 34; the top end is connected with the moving rack 36; the moving rack 36 is engaged with the gear two 32; the bottom end of the elastic piece five 35 is connected with the bottom plate 37 through the pushing frame 34; and the bottom plate 37 is lifted by the limiting assembly.

[0073] In the embodiment two, as shown in the figures 1, 2, 3, 4, 5, 6, 7, 8 and 10-13, the sampling device for mineral exploration is provided. Figures 4-6 The separating mechanism of the embodiment includes the conical rotating disc 8, the mounting part 9, the second spring winding cylinder 10, the L-shaped slot 13, the vertical slot 14 and the recessed block 18.

[0074] The vertical slot 14 is arranged in the sampling inner cylinder 12, and the mounting part 9 is slidingly connected in the vertical slot 14; the second spring winding cylinder 10 is installed in the middle part of the mounting part 9, and the rotating shaft is connected with the conical rotating disc 8; the L-shaped slot 13 is arranged in the sampling inner cylinder 12, and the recessed block 18 is installed on the conical rotating disc 8 and slidingly connected in the L-shaped slot 13; the pull rope 7 is connected with the recessed block 18.

[0075] The opening of the L-shaped slot 13 is provided with the limiting strip, and the recess of the recessed block 18 is slidingly connected with the limiting strip; the size of the recess of the recessed block 18 is smaller than that of the pull rope 7, so that the pull rope 7 cannot pass through the limiting strip of the L-shaped slot 13, thereby avoiding the pull rope 7 entering the sampling inner cylinder 12.

[0076] The first spring winding cylinder 5, the second spring winding cylinder 10 and the third spring winding cylinder 30 are all composed of a cylinder, a spring and a rotating rod; the spring is installed in the cylinder, and the rotating rod is installed at the center of the spring.

[0077] The driving device one 3 is a gas cylinder or the like, and the driving device two 38 is a motor or the like.

[0078] In the embodiment, the mounting frame 1 is installed on a movable vehicle or a movable device, so that the mounting frame 1 moves to a specified position, the external water source input pipeline is connected with the top of the spraying pipe 29, then the driving device one 3 is started to drive the lifting plate 4 to descend, the driving device two 38 is started to drive the sampling outer cylinder 11 to rotate, and then the sampling outer cylinder 11 and the sampling inner cylinder 12 are lowered to drill into the ground, so that the soil sample enters the sampling inner cylinder 12.

[0079] When only facing soft soil and other samples, the sampling outer barrel 11 rotates and drills into the ground, and the water flow flows from the spray head 40 along the spray pipe 29 into the sampling outer barrel 11 and the sampling inner barrel 12 to cool the sampling outer barrel 11 and the sampling inner barrel 12, at this time the conical rotating disc 8 is lowered by the sampling inner barrel 12, and the conical rotating disc 8 pulls the pull rope 7 down, and then the pull rope 7 on the take-up reel 6 is rotated and reduced, and because the push frame 34 is elastically extruded on the surface of the pull rope 7 by the elasticity of the elastic member four 33, when the amount of the pull rope 7 is reduced, the elasticity of the elastic member four 33 drives the push frame 34 to move towards the pull rope 7, the push frame 34 drives the moving rack 36 to move, and then drives the gear two 32 engaged with the moving rack 36 to rotate, thereby driving the rotating disc 31 in the spray pipe 29 to rotate, thereby reducing the water flow resistance area of the rotating disc 31 to the inner cavity of the spray pipe 29, reducing the water flow resistance, and increasing the water flow, thereby realizing that the more the sampling outer barrel 11 and the sampling inner barrel 12 descend, the more the water flow for cooling increases.

[0080] When the lifting plate 4 drives the sampling outer barrel 11 and the sampling inner barrel 12 to descend, the electric take-up reel 39 releases the pressing plate 25, and when facing soft samples, the pressing plate 25 descends and presses the lifting block 27 to descend, at this time the lifting block 27 slows down the descending speed of the pressing plate 25 through the friction between the lifting block 27 and the damping plate 28, and when the sampling outer barrel 11 and the sampling inner barrel 12 face hard samples such as rocks, the descending speed of the sampling outer barrel 11 and the sampling inner barrel 12 decreases, thereby reducing the descending speed of the lifting plate 4 driven by the driving device one 3, and then the pressing plate 25 catches up with the lifting plate 4, thereby pressing the piston shaft one 16 in the inner cavity of the piston cylinder one 15, extruding the air in the inner cavity of the piston cylinder one 15 along the connecting pipe 17 to the inner cavity of the piston cylinder two 19, thereby driving the piston shaft two 20 in the inner cavity of the piston cylinder two 19 to contract away from the rack block 22 in the inner cavity of the piston cylinder two 19, thereby making the rack block 22 descend and separate from the bottom plate 37, and then the moving rack 36 and the bottom plate 37 are pulled down by the tension of the elastic member five 35, thereby making the moving rack 36 move away from the gear two 32, and then the rotating disc 31 is driven by the elasticity of the coil spring cylinder three 30 to be in a vertical state, thereby reducing the water flow resistance area of the rotating disc 31 to the inner cavity of the spray pipe 29, and thereby increasing the water flow from the spray head 40 to the maximum, thereby realizing that when facing hard samples, the water flow is directly adjusted to the maximum.

[0081] When the rack block 22 is lowered, the soft soil is above the conical rotating disc 8 and the mounting portion 9, and the hard object is below the conical rotating disc 8 and the mounting portion 9. The lowered rack block 22 engages with the gear one 23, so that the gear one 23 is reversed, and the winding reel 6 is reversed for a distance, and the pull rope 7 is retracted into the winding reel 6 for a distance, so that the conical rotating disc 8 is moved horizontally along the horizontal section of the L-shaped groove 13, and the mounting portion 9 and the conical rotating disc 8 are staggered, so that the conical rotating disc 8 and the mounting portion 9 separate the soft sample and the hard sample. At this time, the engagement of the rack block 22 and the gear one 23 makes the winding reel 6 unable to rotate again, and the sampling outer cylinder 11 and the sampling inner cylinder 12 continue to descend, so that the conical rotating disc 8 and the mounting portion 9 ascend along the axis of the L-shaped groove 13 and the vertical groove 14. Before the sampling is completed, the conical rotating disc 8 and the mounting portion 9 can be pressed upward by the hard sample at the bottom of the conical rotating disc 8 and the mounting portion 9, so that the soil above the conical rotating disc 8 and the mounting portion 9 is pressed to be precisely blocked.

[0082] Then, after the sampling is completed, the lifting plate 4 drives the sampling outer cylinder 11 and the sampling inner cylinder 12 to ascend and reset. At this time, the pressing plate 25 is still pressed on the piston shaft one 16. When the lifting plate 4 ascends, the elastic member one 21 is pushed upward, so that the rack block 22 ascends and separates from the gear one 23, and the rack block 22 is aligned with the piston shaft two 20.

[0083] Then, the electric winding reel 39 is started to pull the pressing plate 25 to reset, so that the pressing plate 25 separates from the piston shaft one 16. Subsequently, the piston shaft one 16 moves upward in the inner cavity of the piston cylinder one 15 to reset, so that the air in the inner cavity of the piston cylinder two 19 is drawn back into the piston cylinder one 15 along the connecting pipe 17, and the piston shaft two 20 is inserted into the rack block 22 again.

[0084] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application.
