When the clamping assembly is moved downward, the fixed plug block 6 is inserted into the insertion groove 9 and contacts with the fixed clamp block 25. The contact surface between the fixed plug block 6 and the fixed clamp block 25 is an inclined surface. The fixed plug block 6 squeezes the fixed clamp block 25 to slide into the spring groove 10 and squeezes the fixed spring 12 to contract. When the fixed plug block 6 is completely inserted into the insertion groove 9, the fixed groove 7 also moves to the fixed clamp block 25.

The soil cover plate 8 is fixed between them, and then the centrifugal cylinder 17 can be rotated by the driving component to centrifuge the soil moisture. When the centrifugation is completed, the centrifugal cylinder 17 can be replaced and the centrifugation can be continued. When replacing, the operator presses the push plates 11 from both sides of the soil cover plate 8 to push the push plates 11 into the spring grooves 10 until the fixed block 25 is pushed out of the fixed grooves 7 to release the fixation of the soil cover plate 8. Then the centrifugal cylinder 17 can be pulled out of the collection cylinder 4 to insert the centrifugal cylinder 17 filled with new soil into the collection cylinder 4 to continue centrifugation. By quickly installing and disassembling the centrifugal cylinder 17 filled with soil, the device can continue to centrifuge sufficient soil for sampling, thereby ensuring sufficient sampling samples.
