[0047] An auxiliary component, one part of which is slidably disposed in the sampling tube 7 and the other part of which is disposed outside the sampling tube 7, and is mainly used to take out the soil sample stored in the sampling tube 7;

[0048] The fixing seat 11 passes through the bottom wall of the second sleeve 4 and is fixedly arranged on the inner bottom wall of the first sleeve 1. The sampling tube 7 is fixedly arranged on the top wall thereof. The fixing seat 11 is mainly used to fix the sampling tube 7 so that the sampling tube 7 remains stable during sampling.

[0055] In the actual application scenario, the soil taking port 5 is first inserted into the predetermined sampling position, and the handle 10 is rotated to make the soil taking port 5 move downward continuously. During the downward movement, the first sleeve 1 moves synchronously with the soil taking port 5, and the soil taking port 5 passes through the soil at the predetermined sampling position, and the soil passes through the soil taking port 5 into the sampling tube 7. When the first sleeve 1 is inserted to the predetermined soil layer depth, the first support rods 21 on both sides are rotated, and the rotating first support rods 21 drive the first bevel gear 221 to rotate, and the first bevel gear 221 drives the second bevel gear 222 to rotate, and the second bevel gear 222 drives the threaded rod 23 to rotate, and the rotating threaded rod 23 controls the movement of the two groups of semicircular support plates 26 through the threaded sleeve 24 and the L-shaped support plate 25, so that when the two groups of semicircular support plates 26 are combined, the sampling tube 7 The bottom pipe opening is in a closed state, and the bottom pipe opening of the sampling tube 7 is in an open state when the two groups of semicircular support plates 26 are separated. When the sampling tube 7 completes the collection of soil samples, the first support rods 21 on both sides are rotated to merge the two groups of semicircular support plates 26 and close the bottom pipe opening of the sampling tube 7. This avoids the situation where the soil in the sampling tube 7 falls from the pipe opening of the sampling tube 7 when the first sleeve 1 is taken out. Then the first sleeve 1 is pulled out of the soil, and the first support rods 21 on both sides are rotated in opposite directions again to separate the two groups of semicircular support plates 26, thereby opening the bottom pipe opening of the sampling tube 7. Finally, the first pressing plate 32 is pushed, and the first pressing plate 32 drives the second support rod 31 and the second pressing plate 33 to move downward in the sampling tube 7, thereby smoothly discharging the soil sample in the sampling tube 7.

[0056] In summary, by rotating the first support rods 21 on both sides, the two groups of semicircular support plates 26 are controlled to merge or separate, thereby controlling whether the bottom pipe opening of the sampling tube 7 is in an open or closed state. When the sampling tube 7 completes the collection of soil samples, the first support rods 21 on both sides are rotated to merge the two groups of semicircular support plates 26 and close the bottom pipe opening of the sampling tube 7, thereby avoiding the situation that the soil in the sampling tube 7 will fall from the pipe opening when the first sleeve 1 is taken out. When the soil sample in the sampling tube 7 needs to be taken out, the first support rods 21 on both sides are rotated in the opposite direction again to separate the two groups of semicircular support plates 26, thereby opening the bottom pipe opening of the sampling tube 7, and finally taking out the soil sample. In the whole process from collecting the soil sample to taking out the soil sample, the soil in the sampling tube 7 will not fall from the sampling tube 7, thereby ensuring the integrity of the collected soil sample and the accuracy of the soil sample data.
