[0063] As shown, Figure 14 In the embodiment, the baffle sleeve 503 is provided with a baffle cylinder seat 502, and the baffle air cylinder 501 is arranged on the corresponding baffle cylinder seat 502, and the power shaft end of the baffle air cylinder 501 is connected to the corresponding on-off baffle 507 through the connecting shaft 506.

[0064] As shown, Figure 15 In the embodiment, the pressure ring feeding and discharging assembly 6 comprises a horizontal movement module 601, a jaw lifting air cylinder 603 and a pressure ring jaw air cylinder 604, wherein the jaw lifting air cylinder 603 is driven to move horizontally by the horizontal movement module 601, the pressure ring jaw air cylinder 604 is driven to rise and fall by the jaw lifting air cylinder 603, and the two pressure ring jaws 605 are driven to open and close by the pressure ring jaw air cylinder 604 to realize clamping or releasing of the pressure ring 10.

[0065] As shown, Figure 15As shown, in this embodiment, the transverse module 601 can adopt a suitable structural form as needed, such as a rodless cylinder or a motor lead screw and nut structure. The transverse module 601 is provided with a transverse moving seat 6011, and the lower end of the gripper lifting cylinder 603 is fixed on the transverse moving seat 6011. The power shaft end of the gripper lifting cylinder 603 is provided with a gripper lifting seat 6031, and the pressure ring gripper cylinder 604 is provided on the gripper lifting seat 6031. Both moving ends of the pressure ring gripper cylinder 604 are provided with gripper connecting seats 6051, and the gripper connecting seats 6051 are fixedly connected to the corresponding pressure ring grippers 605.

The second mounting plate 902 is provided with a slot for movement.

[0066] like Figures 16-17 As shown, in this embodiment, the pressure ring locking assembly 7 includes a locking bracket 709, and the upper end of the locking bracket 709 is provided with a locking cylinder 702, a first connecting rod 703, a second connecting rod 704, a locking slide 707, and a hinge seat 710.

Figure 17 As shown, during operation, the power shaft of the locking cylinder 702 retracts, pulling the first connecting rod 703 and the second connecting rod 704 towards the side of the locking cylinder 702. This causes the locking slide 707, along with the locking clamping block 705, to retract and release the pressure ring 10. Conversely, the power shaft of the locking cylinder 702 extends, driving the first connecting rod 703 and the second connecting rod 704 to rotate away from the locking cylinder 702. This causes the locking slide 707, along with the locking clamping block 705, to move forward and clamp the pressure ring 10. When the first connecting rod 703 and the second connecting rod 704 are aligned, a dead point position is formed to ensure clamping. In the prior art, the pressure ring 10 is often lifted by the pressing assembly 8 after pressing, generally requiring manual intervention to hammer it.

The spring 804 can play a floating buffering role to avoid damage to the pressing ring 10. In addition, displacement sensors or other elements can be arranged on the pressing floating plate 802 as needed to judge whether it is completely retracted in real time. Only when the pressing floating plate 802 is completely retracted, the next action of the application can be performed.

[0069] The working principle of the application is as follows:

[0070] The working principle of the application is as follows:

[0071] Step one: the split ring plug-in plate 208 in the split ring subassembly 2 is inserted into the socket at the lower end of the split ring split ring seat 207 to output a pressing ring 10.

[0072] Step two: the pressing ring clamp jaw 605 in the pressing ring feeding and discharging assembly 6 clamps the pressing ring 10 and sends it to the pressing station seat on the lower side of the pressing assembly 8.

[0073] Step three: the locking cylinder 702 in the pressing ring locking assembly 7 on both sides of the pressing station seat is started, and moves the locking sliding seat 707 through the first connecting rod 703 and the second connecting rod 704, so that the locking clamping block 705 on the locking sliding seat 707 completes the clamping positioning of the pressing ring 10 on the pressing station seat.

[0074] Step four: the moving adjustment cylinder 306 in the drill cuttings sampling assembly 3 drives the adjustment plate 307 to move and the sampling bucket 304 with the drill cuttings sample moves to the set position, then the discharge plate 305 is driven to retreat by the pushing cylinder 301 so that the quantitative discharge hole 3051 moves to the lower side of the sampling bucket base 3041, then the vibration cylinder 311 on one side of the sampling bucket 304 is started to vibrate the sampling bucket 304 and make the sample fall into the quantitative discharge hole 3051, then the discharge plate 305 is driven to move forward by the pushing cylinder 301 so that the quantitative discharge hole 3051 moves above the compression ring 10 and is exposed from the adjustment plate 307, so that the sample in the quantitative discharge hole 3051 can fall into the compression ring 10, thereby realizing quantitative sampling.

[0075] In addition, in order to improve the work efficiency, the above steps one to three can be synchronized, that is, the compression ring 10 is output while the quantitative sampling of the drill cuttings sample is completed, when the compression ring 10 is confirmed to move to the compression station base and is clamped and fixed, the discharge plate 305 is timely matched to move forward so that the sample in the quantitative discharge hole 3051 falls into the compression ring 10.

[0076] In this step, after the quantitative sampling is completed, the discharge plate 305 retreats to the original position, at this time the dust suction element 310 can start to suck the excess sample in the quantitative discharge hole 3051 into the dust collector, the sampling bucket 304 is moved to the lower side of the funnel brush 106 of the funnel dust removal assembly 1 by the adjustment plate 307, then the funnel brush 106 is driven to descend into the sampling bucket 304 by the brush lifting cylinder 107, and the funnel brush 106 is driven to rotate to realize the cleaning of the residual sample in the sampling bucket 304 by the brush driving device 108, and the fallen residual sample can also be sucked away by the dust suction element 310, thereby ensuring that the inside of the sampling bucket 304 is cleaned and will not affect the input and compression of the next batch of sample.

[0077] Step five: the compression hydraulic cylinder 801 in the compression assembly 8 is started to drive the compression floating plate 802 to move downward with the compression shaft 8011 to complete the tabletting and sampling of the sample in the compression ring 10.

[0078] Step six: after the tabletting and sampling are completed, the compression ring locking assembly 7 on both sides of the compression station base releases the clamping of the compression ring 10, then the compression ring 10 that is completed is clamped by the compression ring clamping jaw 605 in the compression ring feeding and discharging assembly 6 and is sent to the discharging station 204 on the discharging station plate 213 of the compression ring separating assembly 2.

[0079] Step seven: the pressing assembly 4 realizes the cleaning of the pressing contact surface on the upper and lower sides of the pressing station, wherein the first and second dust sweeping devices 405 and 404, the first and second dust sweeping brushes 406 and 407 of the pressing assembly 4 are integrally moved to realize position adjustment through the dust sweeping adjusting frame 403, after being moved to the position, the moving cylinder 4034 on the dust sweeping adjusting frame 403 is started to drive the first and second dust sweeping plates 4032 and 4033 to move forward synchronously and enter between the pressing assembly 8 and the pressing station seat, then the first and second dust sweeping devices 405 and 404 are started to drive the first and second dust sweeping brushes 406 and 407 to rotate, wherein the first dust sweeping brush 406 is used for cleaning the pressing contact surface of the upper pressing assembly 8 (i.e. the lower end of the pressing shaft 8011 shown in FIG. 8B), and the second dust sweeping brush 407 is used for cleaning the pressing contact surface of the lower pressing station seat, and a dust suction head is matched on the moving connecting frame 4031 of the dust sweeping adjusting frame 403 to suck away the residual sample cleaned. Figure 18

[0080] In addition, when the corresponding dust cleaning operation is performed, the on-off baffle 507 in the dust control assembly 5 can be matched with the lifting to realize the dust suction on-off control.​
