In use, the segmented sampling member 210 and the drill bit 220 are fed into the soil at the distribution point by the driving motor 180 and the driving rod 140, and the sampling depth is increased by increasing the number of the segmented sampling members 210. The specific addition manner of the segmented sampling piece 210 is as follows: the connecting bolts of the first shell 2111 and the annular fixing plate are removed, the upper end of the first shell 2111 on the added segmental sampling piece 210 is connected to the annular fixing plate through the bolts, the height of the first shell 2111 is adjusted, the lower end of the added first shell 2111 is connected with the upper end of the original first shell 2111, the first slots 2112 on the adjacent first shells 2111 are distributed in a staggered mode, at the moment, the original fixture blocks 2123 penetrate through the sliding grooves 2113 on the lower end of the added first shell 2111, the fixture blocks 2123 penetrating through the sliding grooves 2113 are inserted into the first reinforcing sleeve 2124 on the lower end of the added second shell 2121, and the prismatic rods 2133 between the adjacent segmental sampling pieces 210 are inserted into the inner prismatic sleeves 2132.

After the segmented sampling piece 210 is fed into soil, the driving rod 140 drives the segmented sampling piece 210 to be pulled up by the height of one segmented sampling piece 210, the fixture block 2123 of the second shell 2121 at the top end drives the second shell 2121 on the segmented sampling piece 210 to rotate in the first shell 2111, so that the first slot 2112 and the second slot 2122 correspond to each other, at the moment, the box body 2161 is exposed through the first slot 2112 and the second slot 2122, and the sampling body 217 is exposed along with the box body 2161, so that the step of exposing the sampling body 217 is completed.

The screw rods 2131 are driven to rotate by rotating the prism rods 2133 on the top end subsection sampling piece 210, the adjacent screw rods 2131 are mutually linked through the prism rods 2133 and the inner prism-shaped sleeve 2132 to rotate, the screw rods 2131 drive the adjusting sleeve 214 to move in the up-and-down direction through the screw thread transmission principle, the adjusting sleeve 214 drives the connecting rod 215, the connecting rod 215 drives the sliding box 2171 to slide in the box body 2161, and the sliding box 2171 drives the triangular sampling sleeve 2172 to break the soil and insert the soil into the triangular sampling sleeve 2172, so that the step of extending out of the sampling body 217 is completed.

When the driving rod 140 is started to drive the segmented sampling member 210 to fall, the triangular sampling sleeve 2172 moves downwards under the action of the driving rod 140, soil at the lower end of the triangular sampling sleeve 2172 further enters the triangular sampling sleeve 2172 to finish the sampling step of the sampling sleeve 2172, the prism rod 2133 is rotated reversely, the prism rod 2133 drives the sampled sampling sleeve 2172 to be withdrawn into the box body 2161, at the moment, the box body 2161 seals two ends of the sampling sleeve 2172 to store soil samples, and the step of withdrawing the sampling sleeve 2172 is finished.

The second housing 2121 of the segmented sampling element 210 is driven by the block 2123 of the second housing 2121 at the top end to rotate in the first housing 2111, so that the first housing 2111 seals the second slot 2122, and the sampling sleeve 2172 is sealed by the first housing 2111, thereby completing the step of sealing the sampling sleeve 2172.

Finally, the segmented sampling member 210 is taken out in segments through the driving rod 140, and then the sampling sleeve 2172 is taken out, and the soil sample inside is taken out to be stored separately. Each section segmentation sampling piece 210 all can take a sample alone, and one-time operation alright is accomplished, and the different degree of depth is taken a sample to the soil sample that takes out only has the soil sample in the sampling sleeve 2172, makes the weight of soil sample less than full length sample weight, is convenient for transport and save, and the soil sample length that every sampling sleeve 2172 took out is unified relatively, and the length of taking out the soil sample is also great relatively the soil sample depth range of depthkeeping degree sample, is convenient for expand multiple spot sample detection investigation.
