[0002] Ring sampling is a commonly used soil sampling technique, mainly used to obtain soil profile characteristics and in-situ soil samples. Ring sampling includes the following steps: selecting the ring; cleaning the sampling site; inserting the ring; rotating the ring; removing the ring; sealing the sample; recording information and finally transporting the sample. The soil sample is sent to the laboratory for analysis to ensure the freshness and accuracy of the sample.
[0003] However, in actual soil testing, the ring knife is usually sealed and transported to a storage room for storage after sampling is completed, and then tested one by one. Due to other external reasons, the testing cycle is relatively long, and the soil samples have been stored inside the ring knife. During actual testing, the soil samples inside the ring knife become hard and compact due to long-term storage, and it is difficult to remove them completely from the ring knife. During the removal process, there is a large amount of residue inside the ring knife, which affects subsequent sampling. Utility Model Content
