when drilling, the contact pad 370 presses the ground (equivalent to the ground pressing the contact pad 370) with the depth of the drill hole, the elastic component 340 compresses, the floating hollow rod 320 moves upwards, the water in the space formed by the drill barrel 012 and the sliding plate 110 is discharged into the floating hollow rod 320, and is continuously sprayed to the inner wall of the drill barrel 012 by the water outlet 322 to cool the drill rod (in the water spraying process, a small amount of water flows out from the rope placing groove 470 to participate in cooling);
reaching the target drilling depth to finish sampling drilling;
thereafter, the drill rod is controlled to move downwards continuously until the sliding plate 110 moves upwards to a specific position (the position can be controlled by selecting different elastic forces and/or different lengths of the magnetic elastic rope 440 according to actual needs), the pulling force applied to the elastic part 442 is greater than the attraction force of the positioning magnetic block 443 to the inner wall of the rope groove 470, and the bottom of the positioning magnetic block 443 is separated from the inner wall of the rope groove 470; the magnetic elastic rope 440 pulls the glue-extruding piston 420 to move upwards, the hot melt glue 460 (the hot melt glue 460 is melted into liquid due to friction heating of the drill rod in the rotation process of the drill barrel 012) is extruded out from the glue storage bin 410, and the columnar sampling material (utilizing the solidified hot melt glue 460) is fixed on the inner wall of the drill barrel 012;
when the hot melt adhesive 460 cools (the hot melt adhesive 460 mainly plays a role of filling and plays a role of bonding to a certain extent), the drill barrel 012 is taken out from the ground together with the columnar sampling material; finally, the cylindrical sampling material is taken out of the drill 012 (the sampling material is squeezed out by pouring water into the space formed by the drill 012 and the slide plate 110 when the taking out is difficult), and is packed into a cylindrical packing bag.
