[0035] Working principle: When working, the bottom plate 1 is pushed to rotate the universal wheel 43 at the lower end of the support column 41, thereby moving the device to a suitable position, thereby starting the self-locking structure on the universal wheel 43, thereby fixing the universal wheel 43, and then starting the driving structure 3 to fix the output end of the driving motor 33, thereby rotating the worm 32. At this time, since the worm 32 and the worm wheel 31 are meshed with each other, the worm wheel 31 rotates, thereby rotating the threaded rod 51. At this time, the sampling sleeve 53 slides downward under the action of the limit rod 52, thereby sampling the soil sample at a specific address;

[0036] When sampling is completed, the output end of the driving motor 33 is reversed, so the worm 32 rotates in the opposite direction, and then the worm wheel 31 is reversed, so the threaded rod 51 rotates in the opposite direction, and then the sampling sleeve 53 slides upward. At this time, the pushing structure 6 is started, so that the output end of the pushing motor 61 rotates, and then the pushing threaded rod 62 rotates. At this time, due to the limiting groove opened in the inner cavity of the groove at the lower end of the threaded rod 51, the pushing threaded sleeve 63 slides up and down, so the pushing plate 64 slides up and down, thereby pushing out the soil sample in the inner cavity of the sampling sleeve 53.

Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
