TECHNICAL FIELD

[0001] The present application relates to the technical field of soil sampling equipment, and particularly relates to a flip pedal type electric soil sampling equipment. BACKGROUND

[0002] Soil sampling refers to a method for collecting soil samples, including sampling layout and sampling technology. It refers to the process of taking a representative part of soil from the field, field, culture or cultivation unit. The soil sample obtained by sampling is prepared into an analysis sample after proper treatment. The test sample taken for analysis and determination is only a few grams or even zero point several grams, and the analysis result should represent the whole soil. Therefore, a representative average sample must be correctly taken, otherwise even if the analysis process is accurate, it is useless, and even can lead to wrong conclusions, causing unnecessary losses to production or scientific research. Sampling is generally divided into single-point samples and mixed samples. Single-point samples are samples that only take one point, which can be divided into disturbed samples, undisturbed samples and profile samples. When taking profile soil samples, the profile should be repaired and cleaned after observation and recording.

[0003] Before sampling, the profile should be repaired and cleaned, and the surface floating soil should be removed, and then the sample should be taken from the center of the typical part layer by layer from top to bottom.

[0004] At present, soil sampling is mainly manually operated, and the sampling pipe is inserted into the soil to rotate and sample. However, when the soil inside is sticky, the internal sampling efficiency is very low, and the operation is very troublesome, time-consuming and laborious. SUMMARY
