Technical Field

[0001] The utility model belongs to the technical field of soil detection, and particularly relates to a soil sample presser. Background Technique

[0002] A soil sample presser is a device specifically used to compact relatively loose soil samples. During the process of soil detection, compacting the soil sample is a crucial step. The purpose is to simulate or approximate the true physical state of the soil under specific conditions. Through the compaction process, researchers can more accurately evaluate the engineering properties or behaviors of the soil, thereby obtaining more reliable detection results.

[0003] However, when traditional soil sample pressers are in use, they generally rely on manual operation. This operation method not only has a large labor intensity, but also, due to design limitations, it is usually difficult to conveniently take out the compacted soil from the device after the soil compaction work is completed. This not only increases the physical consumption of the user, but also causes inconvenience in operation and affects the efficiency of soil detection work. For example, the patent document with the authorized application number 201720015258.8 has the above technical problems.

[0004] Therefore, it is necessary to provide a new soil sample presser to solve the above technical problems. Content of the Utility Model
