In the process of opening the fixing plates 4016, when the four fixing plates 4016 are in contact with the limiting frame 4021, the first electric push rod 403 and the second electric push rod 4011 stop working, the four fixing plates 4016 are limited through the limiting frame 4021, and the opening angle of the four fixing plates 4016 is prevented from being too large, so that the difficulty is too high when the device is retracted.

After the device is fixed, a worker starts the servo motor 102, an output shaft of the servo motor 102 drives the first connecting column 1021 and the first friction ring 1022 to rotate, the first connecting column 1021 drives the connecting shell 1024 to rotate, the connecting shell 1024 drives the transmission column 1025 to rotate through the second connecting column 1027, at the moment, part of a limiting block on the first baffle 10251 is positioned in a groove on the fixed shell 103, the transmission column 1025 rotates to be matched with a thread groove on the fixed shell 103, the transmission column 1025 moves downwards, the transmission column 1025 drives the first baffle 10251 to move downwards, until a limiting block on the first baffle 10251 is matched with the groove on the fixed shell 103, at the moment, part of threads arranged on the transmission column 1025 still are positioned in the thread groove of the fixed shell 103, the transmission column 1025 rotates to drive the fixed shell 103 to rotate, in the process, the worker manually rotates the rocking rod 203, the rocking rod 203 drives the transmission rod 202 to rotate through the first bevel gear 204 and the second bevel gear 205, the transmission rod 202 rotates the transmission fixed ring 2 to move downwards, the fixed shell 103 moves downwards, the fixed shell 103 drives the fixed shell 103 to move downwards, and the fixed shell 103 drives the first sampling tube 104 to move downwards, and the screw 103 to rotate to drill automatically.

In the process that the fixed shell 103 moves downwards, the fixed shell 103 drives the protective shell 105 to move downwards, the protective shell 105 drives the limit shell 3 to synchronously move downwards, the limit shell 3 drives the two wedge-shaped limiting blocks 301 to move downwards, in the process, the two wedge-shaped limiting blocks 301 are matched with the wedge-shaped grooves on the outer shell 1, when the inclined planes of the two wedge-shaped limiting blocks 301 and the inclined planes of the wedge-shaped grooves on the outer shell 1 gradually lose contact, the two wedge-shaped limiting blocks 301 move towards each other, the connecting spring 302 arranged in the middle of the connecting spring is extruded until the upper ends of the two wedge-shaped limiting blocks 301 and the inclined planes of the wedge-shaped grooves on the outer shell 1 lose contact, at the moment, the connecting spring 302 is compressed to a limit state, when the two wedge-shaped limiting blocks 301 continue to move downwards and are matched with the wedge-shaped grooves on the outer shell 1 again, the connecting spring 302 resets the two wedge-shaped limiting blocks 301 to push the two wedge-shaped limiting blocks 301 to the opposite directions until the inclined planes of the two wedge-shaped limiting blocks 301 are contacted with the inclined planes of the wedge-shaped grooves on the outer shell 1, at the moment, the upper end faces of the two wedge-shaped limiting blocks 301 are contacted with the upper end faces of the wedge-shaped grooves on the outer shell 1, the limit shell 3 is limited, and then the protective shell 105 is prevented from moving upwards.

In the above process, when the sampler moves downwards and encounters a hard material or a plant rhizome to clamp the cutter teeth arranged at the bottom end of the first sampling tube 104, the first sampling tube 104 rotates and encounters resistance, the rotating torque of the first sampling tube is increased, the rotating speed of the output shaft of the servo motor 102 and the rotating speed of the transmission column 1025 generate a difference value, when the torque is increased to a certain extent, the rotation of the output shaft of the servo motor 102 can enable the first connection column 1021 to press the connection shell 1024 downwards, the spring 1026 is compressed, the output shaft of the servo motor 102 and the transmission column 1025 gradually lose fit until the first friction ring 1022 is in contact with the second friction ring 1023, the second connection column 1027 is positioned at the upper part of the vertical part of the 7-shaped groove on the connection shell 1024, the first friction ring 1022 drives the second friction ring 1023 to rotate under the action of the friction force between the first friction ring 1022 and the second friction ring 1023, the second friction ring 1023 drives the connection shell 1024 to rotate until the horizontal part of the 7-shaped groove formed on the connection shell 1024 is matched with the second connection column 1027, and the worker stops the servo motor 102.

Then, the staff reversely rotates the rocker 203 to enable the screw rod 202 to reversely rotate, and drives the fixing ring 2, the fixing shell 103 and parts connected with the fixing ring and the fixing shell to reset upwards, in the process, the fixing shell 103 moves upwards to lose contact with the protecting shell 105, at the moment, the protecting shell 105 does not move upwards under the cooperation of the two wedge-shaped limiting blocks 301 and the wedge-shaped grooves on the outer shell 1 and cannot move upwards due to the friction force between the inner wall of the protecting shell and the outer wall of the first sampling tube 104, so that samples drilled by the first sampling tube 104 are protected, and the samples drilled by the first sampling tube 104 are prevented from falling down due to the upward movement of the first sampling tube 104 and are contacted with soil at the peripheral positions of the samples drilled by the first sampling tube 104, so that the samples obtained by the first sampling tube 104 are polluted by surrounding soil.

In the process that the first sampling tube 104 moves upwards, the cutter teeth on the first sampling tube 104 pass through the bottom end of the protective shell 105, and sundries clamped between the cutter teeth of the first sampling tube 104 are removed by the bottom end of the protective shell 105, so that the sundries are prevented from being wound on the cutter teeth of the first sampling tube 104, and the upward movement of the first sampling tube 104 is affected.

After the sundries are removed, the worker manually resets the connecting housing 1024 to enable the arc-shaped groove on the connecting housing 1024 to be matched with the first connecting column 1021 again, at this time, the servo motor 102 is restarted, and the first sampling tube 104 and other parts are reset downwards again through the transmission of the rocker 203 until the fixing housing 103 is matched with the protecting housing 105 again.

After the sampling is finished, the worker stops the servo motor 102, meanwhile, the rocker 203 is rotated reversely to drive the screw 202 to rotate reversely, the screw 202 drives the fixed ring 2 and other parts connected with the fixed ring 2 to move upwards, after the fixed ring 2 is reset to the initial position, the worker stops rotating the rocker 203 and presses the two unlocking plates 303 to move oppositely, the unlocking plates 303 drive the adjacent wedge-shaped limiting blocks 301 to move and compress the connecting springs 302, when the connecting springs 302 are compressed to a limit state, the upper ends of the two wedge-shaped limiting blocks 301 are not matched with inclined surfaces of wedge-shaped grooves on the outer shell 1 any more, the protective shell 105 is not limited any more, at the moment, the worker can manually reset the protective shell 105 to the initial position, then the worker restarts the first electric push rod 403 and the second electric push rod 4011, and after the supporting legs 401 are unlocked and reset to the initial position, the worker stops the first electric push rod 403 and the second electric push rod 4011.
