[0030] Working principle: when in use, the core to be sampled is placed on the top of the placement plate, and then the two first electric telescopic rods 4 are controlled to open in the forward direction through the synchronous control switch, and the output shaft of the first electric telescopic rod 4 drives the cross plate 3 to move downward, and the cross plate 3 drives the mounting plate 7 to move downward through the electric slide rail 6, and the mounting plate 7 drives multiple sample dividing tubes 8 to move downward. While the sample dividing tubes 8 move downward, the core is squeezed and cut for sampling. Under the squeezing force, the core is squeezed into the corresponding sample dividing tube 8. After sampling, the two first electric telescopic rods 4 are started in the reverse direction, so that the multiple sample dividing tubes 8 are transformed into upward back movement and reset. By driving multiple sample dividing tubes 8 of different specifications to move synchronously for sampling, different amounts of samples can be obtained at the same time. Compared with the manual sampling method, the working efficiency is significantly improved;

[0031] After the sampling is divided, the mounting plate 7 is driven to move to the right by the electric slide rail 6, and the mounting plate 7 drives multiple sample dividing tubes 8 to move to the right at the same time. When the rightmost sample dividing tube 8 moves to the right above the release hole 1, the push rod can be pushed to the right, and the push rod drives the arc baffle 2 to move to the right to remove the obstruction of the release hole 1. At this time, one of the sample dividing tubes 8 is aligned with the top counterweight collection box 102, and then the corresponding multi-stage electric telescopic rod 10 is started in the positive direction, and the output shaft of the multi-stage electric telescopic rod 10 drives the corresponding push block 9 to move downward to squeeze the sample inside the sample dividing tube 8. Under the squeezing force, the sample is gradually moved out of the corresponding sample dividing tube 8 and falls into the top counterweight collection box 102, and then the corresponding multi-stage electric telescopic rod 10 is started in the reverse direction, so that the corresponding push block 9 is transformed To move back and reset upward, the brake motor 103 is then turned on in the positive direction, and the output shaft of the brake motor 103 drives the circular plate 101 to rotate, and the circular plate 101 drives the multiple counterweight collection boxes 102 to rotate. When another counterweight collection box 102 moves to align with the release hole 1, the brake motor 103 is stopped, and the electric slide 6 is started. The electric slide 6 drives the multiple sample dividing cylinders 8 to continue to move to the right through the mounting plate 7. When another sample dividing cylinder 8 moves to align with the release hole 1, the electric slide 6 can be stopped, and another multi-stage electric telescopic rod 10 is turned on to push the discharge, and so on. After the samples inside the multiple sample dividing cylinders 8 are taken out and collected, the electric slide 6 can be started again. When the multiple sample dividing cylinders 8 move to align with the corresponding annular sleeves 14, the electric slide 6 is stopped.

[0032] Then, the two first electric telescopic rods 4 are opened forward again, so that the multiple sample dividing tubes 8 move downward and are respectively inserted into the corresponding annular sleeves 14, and the water pump 13 is turned on while the sample dividing tubes 8 move. The water pump 13 extracts water from the water tank 11 through the suction pipe, and the extracted water is discharged into the horizontal pipe 12. A part of the water in the horizontal pipe 12 enters the leftmost annular sleeve 14 through the connecting vertical pipe, and enters the next annular sleeve 14 through the leftmost annular sleeve 14, and so on, so that the water enters the multiple annular sleeves 14, and at the same time, another part of the water in the horizontal pipe 12 enters the multiple first vertical pipes 15, and the first vertical pipes 15 are connected to the first vertical pipe 15. The water inside 15 and the water inside the annular sleeve 14 are sprayed out through the corresponding second nozzle 17 and the first nozzle 16 respectively. The water sprayed by the second nozzle 17 rinses the inner wall of the sample dividing tube 8, and the water sprayed by the first nozzle 16 rinses the outer side of the sample dividing tube 8, so that the inside and outside of the sample dividing tube 8 can be rinsed at the same time. This flushing method does not require manual cleaning operation by personnel, and improves the cleaning effect. After cleaning, the two first electric telescopic rods 4 can be reversely started, so that the multiple sample dividing tubes 8 are all transformed to move back and reset upward, and the electric slide rail 6 can be started again, so that the multiple sample dividing tubes 8 are moved to the top of the placement plate again, and can wait for the next sample dividing operation.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
