Description

Technical Field

[0001] The invention relates to the technical field of soil sampling auxiliary tools, and in particular to a high-efficiency electric precision looping knife device and a control method thereof. Background Art

[0002] In the soil sampling process, a knife ring is usually used to sample the bulk density of the soil. The traditional soil bulk density sampling method is for the sampler to manually hammer the knife ring handle with a rubber hammer and hammer the knife ring into the soil to complete the sampling. In this process, uneven force often occurs when the knife ring handle is hammered manually, resulting in the knife ring being unable to be evenly and vertically embedded in the soil. When encountering gravel in the soil, samplers often find it difficult to detect the presence of gravel, which causes the knife ring to be damaged and deformed. When knife ring sampling is performed on a section perpendicular to the ground, the knife ring often tilts, which causes a large deviation in the knife ring sampling results.

[0003] Therefore, an efficient electric precision looping knife device and a control method thereof are proposed to solve the above problems. Summary of the invention
