Sample tubes 2 are detachably installed in the plurality of tube holes 3 through the lifting mechanism 8, and the upper ends of the plurality of sample tubes 2 are extended to the outside, and the outer surfaces of the upper ends of the plurality of sample tubes 2 are provided with threads 9, and tube covers 7 are detachably installed on the upper ends of the plurality of sample tubes 2 through the threads 9, and the plurality of sample tubes 2 are fixedly penetrated by limit plates 10 located below the threads 9, and the upper surface of the collecting barrel 1 is fixedly installed with the same number of mounting rods 11 as the tube holes 3, and the plurality of mounting rods 11 are respectively distributed in a circular array between every two groups of tube holes 3, and the upper surfaces of the plurality of mounting rods 11 are rotatably installed with pressure plates 12.

[0023] After the sample is loaded, the lower surface of the limit plate 10 will be in contact with the upper surface of the collecting barrel 1. After the core sample is loaded, the pressing plate 12 on the mounting rod 11 is rotated to rotate so that the lower surfaces of both ends are respectively in contact with the upper surfaces of the two groups of limit plates 10 to fix the sample loading barrel 2 in the barrel loading hole 3, thereby improving the stability of the sample loading barrel 2 during transportation. When transporting it to the laboratory for testing, the pressing plate 12 is first rotated to one side, and then the lifting mechanism 8 simultaneously lifts the multiple groups of sample loading barrels 2 out of the barrel loading hole 3, and then the staff takes them out in turn and places them in order for testing, thereby solving the problem that it is not convenient to mark and sort the sample cores in an orderly manner when taking them out, so that the samples are easily broken and chaotic during collection, which makes it inconvenient to distinguish the depth of the core samples during testing.

[0024] Furthermore, rubber pads 5 are fixedly installed on the inner bottom surfaces of the multiple groups of barrel holes 3, and connecting ports 4 that penetrate into the hollow are opened on one side surface of the multiple groups of barrel holes 3 located at the hollow part of the collecting barrel 1, and the multiple groups of connecting ports 4 are all set to be rectangular.

[0025] During operation, the design of the rubber pad 5 can reduce the bumping of the sample loading tube 2 during transportation, thereby improving its protection. The design of the connecting port 4 can enable the lifting mechanism 8 to lift the sample loading tube 2 to the outside of the collecting barrel 1.

[0026] Furthermore, acrylic slots 6 are fixedly mounted on the upper surfaces of the multiple sets of barrel covers 7 .

[0027] During operation, through the design of the acrylic card slot 6 on the cylinder cover 7, a mark can be inserted into the acrylic card slot 6 after the core sample is loaded, so as to facilitate identification during detection.

[0028] Furthermore, acrylic slots 6 are fixedly installed on the upper surface of the collecting barrel 1 at the multiple groups of barrel holes 3 .

Under the action of the support rods 805, the tray 804 will be supported to move upward in the tube hole 3, thereby achieving the purpose of raising the sample tube 2.

[0034] Working principle: when collecting core samples, they are installed in the sample loading tube 2 in sequence according to the depth of the core samples, and then the tube cover 7 is locked on the sample loading tube 2 through threads to seal it. When the sample loading tube 2 is installed in the tube hole 3, the lower surface of the limit plate 10 will fit against the upper surface of the collecting barrel 1. After loading the core sample, the pressure plate 12 on the mounting rod 11 is rotated so that the lower surfaces of both ends are respectively fitted against the upper surfaces of the two groups of limit plates 10 to fix the sample loading tube 2 in the tube hole 3, thereby improving the stability of the sample loading tube 2 during transportation. When transporting to the laboratory for testing, the pressure plate 12 is first rotated to one side, and then the lifting mechanism 8 lifts multiple groups of sample loading tubes 2 out of the tube hole 3 at the same time, and then the staff removes them one by one and places them in sequence for testing.
