[0023] A motor 6 is provided on the outer surface of the upper end of the connecting disk 5, and the output end of the motor 6 passes through the connecting disk 5 and is fixedly connected to the rotating disk 4. The output end of the motor 6 is rotatably connected to the connecting disk 5, and two groups of handles 8 are symmetrically fixedly connected to the outer surface of the connecting disk 5. When sampling, the operator holds the handle 8 and aligns the drill bit 2 with the sampling area, and then starts the motor 6. The output end of the motor 6 drives the rotating disk 4, the sampling column 1 and the drill bit 2 to rotate, and the operator presses the handle 8 downward, and the drill bit 2 drills the sampling area. The sampling column 1 enters the interior of the soil with the drill bit 2. A plurality of collection cavities 9 are equidistantly opened inside the sampling column 1, and a sampling component 7 is arranged inside the collection cavity 9.

[0024] The sampling assembly 7 includes a connecting hole 701, a rotating rod 702, a baffle 703, a scraper 704 and a blocking bar 705; a connecting hole 701 is opened on one side of the inner surface of each group of collection chambers 9, and the rotating rod 702 is rotatably connected inside the connecting hole 701, the outer surface of the rotating rod 702 is fixedly connected to the baffle 703, and the outer surfaces of both ends of the baffle 703 are fixedly connected to the scraper 704, the outer surface of the scraper 704 is in contact with the outer surface of the connecting hole 701, and the outer surface of one side of the baffle 703 is fixedly connected to the blocking bar 705 near the two sides, and the outer surface of the sampling column 1 is located between two adjacent groups of connecting holes 701 and is fixedly connected to a blocking ring 706, which blocks the sampling between the two adjacent groups of connecting holes 701 to prevent the soil sample from being disturbed.

[0025] A movable hole 13 is opened between two adjacent groups of collecting chambers 9, and a movable rod 14 is movably connected between several groups of movable holes 13. A mounting hole 17 is opened on the outer surface of one side of the connecting rod 3, and a connecting block 18 is movably connected inside the mounting hole 17. A through hole 19 is opened at the bottom end of the inner surface of the mounting hole 17, and the through hole 19 penetrates to the interior of the uppermost collecting chamber 9. A pushing rod 20 is fixedly connected to the outer surface of the lower end of the connecting block 18, and the bottom end of the pushing rod 20 penetrates through the through hole 19 and is fixedly connected to the movable rod 14.

[0026] A connecting ring 21 is movably connected to the outer surface of the connecting rod 3, and the connecting ring 21 is fixedly connected to the connecting block 18. Two groups of electric push rods 22 are symmetrically arranged on the outer surface of the lower end of the rotating disk 4, and one end of the electric push rod 22 is fixedly connected to the rotating disk 4, and the other end is fixedly connected to the connecting ring 21. When the drill bit 2 drills into a certain depth, the motor 6 is turned off and the electric push rod 22 is turned on. The electric push rod 22 repeatedly pushes and pulls the connecting ring 21 up and down, and the connecting block 18 drives the fixed rod to push and pull the push rod 20 and the movable rod 14 up and down.

[0027] A plurality of groups of teeth 15 are fixedly connected at equal distances to the outer surface of one side of the movable rod 14 and the corresponding position of each group of rotating rods 702. A gear 16 is fixedly connected to the outer surface of the rotating rod 702 and the corresponding position of the movable rod 14, and the gear 16 is meshed with the teeth 15. Driven by the teeth 15, the gear 16 drives the rotating column 10 to rotate forward and reverse repeatedly.

[0028] The outer surface of the rotating column 10 is wound with a traction rope 11 and a traction rope 2 12, and one end of the traction rope 11 and the traction rope 2 12 is fixedly connected to the rotating column 10, and the ends of the traction rope 11 and the traction rope 2 12 away from the rotating column 10 are respectively connected to the outer surface of one side of the baffle 703 near the two ends, and the winding directions of the traction rope 11 and the traction rope 2 12 are opposite. When the rotating column 10 rotates clockwise, the traction rope 11 is wound and the traction rope 2 12 is unwound, so the traction rope 11 pulls the baffle 703 to rotate clockwise, and the scraper 704 at one end of the baffle 703 flips outward and scrapes the soil for sampling.

[0031] Step 2: When the drill bit 2 drills into a certain depth, the motor 6 is turned off and the electric push rod 22 is turned on. The electric push rod 22 repeatedly pushes and pulls the connecting ring 21 to move up and down. The connecting block 18 drives the fixed rod to push and pull the push rod 20 and the movable rod 14 up and down. The gear 16 drives the rotating column 10 to repeatedly rotate forward and reverse under the drive of the teeth 15.

[0032] Step 3: When the rotating column 10 rotates clockwise, the traction rope 11 is wound up and the traction rope 2 12 is unwound, so the traction rope 11 pulls the baffle 703 to rotate clockwise, and the scraper 704 at one end of the baffle 703 turns outward and scrapes the soil for sampling. The baffle 703 continues to move clockwise, and the soil falls on the surface of the baffle 703 and enters the inside of the collection chamber 9 along its surface for collection;

[0033] Step 4: When the rotating column 10 rotates counterclockwise, the traction rope 2 12 is reeled in, and the traction rope 1 11 unwinds the baffle 703 to restore its original state, blocking the connecting hole 701 to prevent the soil at other depths from entering the collection chamber 9 during the process of taking out the sampling column 1, thereby ensuring the accuracy of sample collection.
