[0021] The front and rear surfaces of the first vertical rod 2 and the front and rear surfaces of the second vertical rod 3 are longitudinally provided with guide grooves 6. The first vertical rod 2 and the second vertical rod 3 are both installed with support mechanisms 7, which include a mounting frame 71, bolts 72 and guide blocks 73.

[0022] The model of the servo motor 41 is ACSM110-G04030LZ, and the model of the electric motor 46 is YE2.

[0023] Working principle: When using this device, move the first vertical rod 2 and the second vertical rod 3 to the ideal position. At this time, the bottom of the first vertical rod 2, the bottom of the second vertical rod 3 and the bottom of the anti-slip tube 9 are all in contact with the ground. At this time, loosen the bolt 72, and then hold the installation frame 71 and move it downward. At this time, the first reinforcement rod 74 and the second reinforcement rod 75 can be driven to move. After the first reinforcement rod 74 and the second reinforcement rod 75 move, they can drive the first support rod 76 and the second support rod 77 to gradually expand until the first support rod 76, the second support rod 77 and the bottom of the first vertical rod 2 are parallel. At this time, tighten the bolt 72, and then insert the insertion rod 78 into the surrounding soil The device can be stably supported in the middle, and then the servo motor 41 is controlled to rotate forward, so that the bidirectional screw rod 411 can be driven to rotate forward. After the bidirectional screw rod 411 rotates forward, it can drive the first adjustment block 412 and the second adjustment block 413 to move relative to each other. Since the limit block 45 is slidably connected in the limit groove 5, the first adjustment block 412 and the second adjustment block 413 can drive the first bracket 42 and the second bracket 43 to move after the relative movement, and then drive the fastening rod 44, the motor 46 and the screw rod 47 to move downward. After the screw rod 47 moves downward, it can pass through the anti-slip cylinder 9. When the bottom of the screw rod 47 contacts the ground, the motor 46 is turned on. At this time The rotating screw rod 47 can be driven to move downward continuously, so that the screw rod 47 can continuously penetrate into the soil for sampling, and then the motor 46 is turned off. At this time, the screw rod 47 is in a stationary state, and then the servo motor 41 is controlled to reverse, so as to drive the bidirectional screw rod 411 to reverse. After the bidirectional screw rod 411 reverses, it can drive the first adjustment block 412 and the second adjustment block 413 to move in the opposite direction. Since the limit block 45 is slidably connected in the limit groove 5, the first adjustment block 412 and the second adjustment block 413 can drive the first bracket 42 and the second bracket 43 to move after the opposite movement, thereby driving the fastening rod 44, the motor 46 and the screw rod 47 to move. The rotating rod 47 moves upward, and the spiral rod 47 can move into the anti-slip tube 9 after moving upward. Since the distance between the outer diameter of the spiral rod 47 and the inner diameter of the anti-slip tube 9 is 0.1 cm, the soil on the spiral rod 47 will not fall off from the anti-slip tube 9. As the servo motor 41 continues to reverse, until the bottom of the spiral rod 47 moves out from the top of the anti-slip tube 9, the user can then use an external tool to remove the soil on the spiral rod 47. At the same time, when the spiral rod 47 is slowly moved out of the anti-slip tube 9, the user can also remove the soil on the spiral rod 47 that is currently exposed to the outside. Both methods can complete the removal of the soil on the spiral rod 47.
