[0054] Working principle: the sampling vehicle 1 is placed on the wetland surface, the sampling vehicle 1 opens the adjustment mechanism through the control center 11, the adjustment mechanism pushes out the sampling body 2 and moves downward, the sampling knife 50 moves downward to cut the wetland surface, and as the sampling body 2 continues to move downward, the sampling knife 50 moves downward inside the wetland, and the sampling knife 50 moves downward to drive the sampling chamber 4 to move downward inside the wetland. In the initial state, the two blocking plates 56 do not block the through slots 51, and the through slots 51 of the two auxiliary chambers 53 are interconnected with the sampling chamber 4 after the two auxiliary chambers 53 are merged, and the first toothed disc 523 is not meshed with the blocking plate 56 and the auxiliary chamber 53, and the first toothed disc 523 is not meshed with the second toothed disc 55 The meshing connection is that when the sampling tube moves downward, the wetland soil preferentially enters the auxiliary device 5, and the control center 11 is used to turn on the second rotary drive component 52. The second rotary drive component 52 is turned on to drive the second rotating shaft 520 to rotate. The second rotating shaft 520 rotates to drive the second linear drive component 521 to rotate. The second linear drive component 521 rotates to drive the first gear plate 523 to rotate through the second output rod 522. The first gear plate 523 rotates to drive the second gear plate 55 to rotate. The second gear plate 55 rotates to drive the third movable wheel 54 away from the center of the auxiliary device 5 to rotate. The third movable wheel 54 at this location rotates through the second movable belt 540 can drive the third movable wheel 54 near the center of the auxiliary device 5 to rotate, and the rotation of the four third movable wheels 54 drives the four third shafts 531 to rotate, and the rotation of the four third shafts 531 drives the four separation rollers 532 to rotate. Since the movable roller 530 is arranged between the two third separation rollers 532 on the left and right sides, and the spacing between the separation rollers 532 and the movable rollers 530 is small, when the wetland soil enters the auxiliary device 5, the wetland soil is preferentially pried apart by the two separation rollers 532 on the left and right sides, and the pried apart wetland soil samples can be passed through the separation rollers 532 and the separation rollers 532 as the separation rollers 532 move. The gap between the movable roller 530 and the gap between the separation roller 532 and the auxiliary chamber 53 enters the sampling chamber 4 for sampling, and the stones in the soil after being scraped away will be discharged from the auxiliary device 5 under the blocking of the separation roller 532 and the movable roller 530. In the initial state, the first movable plate 34 is staggered in the second movable plate 35, that is, the through holes at the first movable plate 34 and the second movable plate 35 are staggered and cannot flow normally. At this time, the sampling chamber 4 is a closed space that can normally accommodate wetland soil samples, avoiding stones from being collected as samples when sampling wetland soil, thereby reducing the total amount of samples collected at a single time, improving the sampling quality of the device, and facilitating user use;

[0055] After the wetland soil sampling is completed, the second linear drive assembly 521 is turned on, the second linear drive assembly 521 is turned on to push out the second output rod 522 and move it backward, the second output rod 522 moves to drive the first gear disc 523 to disengage from the second gear disc 55 and move backward, until the first gear disc 523 is meshed and connected with the auxiliary bin 53 and the blocking plate 56, at this time, the second rotary drive assembly 52 is turned on by the control center 11, the second rotary drive assembly 52 is turned on to drive the second rotating shaft 520 to rotate, and the second rotating shaft 520 rotates to drive the second linear drive assembly 521 and the second output rod 55 22 is rotated, the second output rod 522 rotates to drive the first toothed disc 523 to rotate, and the first toothed disc 523 rotates to drive the blocking plate 56 to move toward the center of the auxiliary device 5 through the latch teeth, and the auxiliary chamber 53 moves away from the center of the auxiliary device 5, until the two blocking plates 56 are combined to block the through groove 51. At this time, the external soil cannot continue to enter the sampling chamber 4, and the wetland soil sample in the sampling chamber 4 cannot be discharged to the outside, so as to avoid the sampling soil being pulled out by the outer soil when the device is reset after sampling, thereby improving the sampling effect of the device and facilitating the use of the user;

[0056] After the above steps are completed, the control center 11 is used to turn on the first linear drive component 30. The first linear drive component 30 is turned on to push out the first output rod 300 and move it to the right. The first output rod 300 moves through the mounting bracket 31 and the first shaft rod 310 to drive the first bevel gear 32 to move until the first bevel gear 32 moves to the second bevel gear 371 and the first bevel gear 32 is meshed with the second bevel gear 371. The relative movement of the first bevel gear 32 drives the fixed plate 320 to move. The movement of the fixed plate 320 drives the screw rod 321 to move in the movable hole. The movement of the screw rod 321 drives the through rod 33 and the first movable plate 34 to move in the second movable plate 35 through the movable groove 350. When the first bevel gear 32 is meshed with the second bevel gear 371, the first bevel gear 32 is engaged with the second bevel gear 371. The through holes at the first movable plate 34 and the second movable plate 35 correspond to each other. At this time, the control center 11 is used to turn on the first rotation drive component 36. The first rotation drive component 36 is turned on to drive the first rotating shaft 360 to rotate. The first rotating shaft 360 rotates to drive the first movable wheel 361 to rotate. The first movable wheel 361 rotates through the first movable belt 362 to drive the second movable wheel 37 to rotate. The second movable wheel 37 rotates through the second shaft rod 370 to drive the second bevel gear 371 to rotate. The second bevel gear 371 rotates to drive the first bevel gear 32 to rotate. The first bevel gear 32 rotates through the fixed plate 320 to drive the screw rod 321 to rotate. The screw rod 321 rotates to drive the through rod 33, the first movable plate 34, and the second The movable plate 35 moves downward in the sampling chamber 4, and the second movable plate 35 moves downward to squeeze the wetland soil sample, and the squeezed humidity water sample enters the top of the second movable plate 35 through the through holes of the first movable plate 34 and the second movable plate 35. The rotation of the second shaft rod 370 can drive the movable disk 38 to rotate synchronously. The rotation of the movable disk 38 drives the movable column 380 to make a circular motion. The movement of the movable column 380 drives the return groove plate 381 to make a linear reciprocating motion. The movement of the return groove plate 381 drives the movable rod 382 to make a linear reciprocating motion. The linear reciprocating motion of the movable rod 382 drives the piston plate 61 to make a linear reciprocating motion in the separation device 6. When the separation device 6 is in use, it is externally connected to an output tube, an electronic one-way valve and a sample tank. The piston plate 61 linearly reciprocates. When the reciprocating motion moves upward, the wetland water samples separated by the second movable plate 35 and the first movable plate 34 inside the sampling chamber 4 are drawn out into the separation device 6 through the separation tube 60, and the electronic one-way valve is used to prevent the wetland water samples in the sample tank from flowing back into the separation device 6. When the piston plate 61 moves downward in a linear reciprocating motion, the wetland water samples inside the separation device 6 are discharged into the sample tank through the output pipe, and the one-way valve is used to prevent the wetland water samples inside the separation device 6 from flowing back into the sampling chamber 4. Therefore, the device can separate the wetland soil samples and the wetland water samples after the sampling is completed and store them separately. In subsequent detection, the wetland soil samples and the wetland water samples can be detected separately, thereby improving the detection accuracy between each sample, improving the sampling quality of the device, and facilitating user use.
