Description

Soil monitoring sampler

Technical Field

The utility model relates to the technical field of soil sampling, in particular to a soil monitoring sampler.

Background

Soil monitoring is an analytical method used as a field soil composition test to demonstrate the correlation between the measurement results and crop yield. Soil monitoring is to perform chemical and physical analysis and experimental instrument analysis on soil samples, and soil monitoring analysis results are often used for recommending fertilization, and soil testing fertilization is a specific application of soil monitoring technology.

When soil monitoring is carried out, soil samples are required to be firstly collected, a soil sampler is often used, and the sampling principle of the soil sampler is that soil samples in the sampler reach a certain consolidation density by utilizing the mechanical compaction acting force of soil so as to collect the soil samples.

When the existing soil sampler is used for sampling soil, a sampling tube of the soil sampler is inserted into the soil through the control of a handle rod, an integral soil drilling tooth slot is arranged at the operation end of the sampling tube, so that the soil sample is sampled into the sampling tube, after the sampling is completed, the soil sampler is pulled out, and then one end of the soil sampler is pushed to penetrate through a push rod in the sampling tube, so that the soil sample in the sampling tube is pushed out. However, because the soil sample is directly filled in the sampling tube, if the soil sample is dry, the soil sample is easy to loose and spread when being taken out, and the complete soil sample is inconvenient to collect, soil analysis with different depths is carried out, and if the soil sample is moist, the moist soil is easy to adhere to the inner wall of the sampling tube and is difficult to take out, and then the sticky soil sample is inconvenient to clean, so that the problem of soil sample interference is caused during secondary sampling, and the precision of soil sampling is affected. In addition, the integral sampling tube and the soil drilling tooth slot structure at the working end of the sampling tube cannot be used after the working end of the sampling tube is carelessly impacted to rocks in the soil layer and the like are damaged in the sampling process, and the integral sampling tube is required to be replaced and maintained, so that the cost is high.
