[0029] In this embodiment: The crushing mechanism includes a second motor 301. A first rotating shaft 302 is provided at the output end of the second motor 301. A collection cylinder 303 is provided on the first rotating shaft 302. The collection cylinder 303 adopts a split structure of two halves. Two rotating frames 304 are symmetrically arranged at both ends of the bottom of the collection cylinder 303. A second rotating shaft 305 is installed on one side of the rotating frame 304. A rotating blade 306 is provided at one end of the second rotating shaft 305. A drill bit 307 is provided at the bottom end of the first rotating shaft 302. The first rotating shaft 302 is made of 45 steel. The shape of the collection cylinder 303 is a cylindrical tube. The drill bit 307 is welded to the first rotating shaft 302. The first motor 201 drives the lead screw 202 to drive the lifting frame 203 to move downward horizontally. The drill bit 307 continuously descends into the ground to start breaking the soil. The loosened soil passes through the drill bit 307 and enters the collection cylinder 303.

The second motor 301 on the lifting frame 203 drives the first rotating shaft 302 to drive the collection cylinder 303 and the drill bit 307 at the bottom end to rotate. At the same time, the first motor 201 drives the lead screw 202 to drive the lifting frame 203 to move downward horizontally. The drill bit 307 continuously descends into the ground to start breaking the soil. The loosened soil passes through the drill bit 307 and enters the collection cylinder 303. Under the action of the downward pressure, the soil pushes the rotating blade 306 at the bottom of the collection cylinder 303 to drive the second rotating shaft 305 to rotate and open in the rotating frame 304. After the work is completed, the first motor 201 drives the lead screw 202 to drive the lifting frame 203 to move upward horizontally. During the upward movement, the gravity of the soil squeezes the rotating blade 306 to drive the second rotating shaft 305 to rotate and close in the rotating frame 304. Finally, first remove the second rotating shaft 305 and place it horizontally, and then disassemble the collection cylinder 303 separately to complete the stratified sampling of the soil.
