Description

Decomposition Soil Sample Collector

technical field

The invention relates to the field of soil collection, in particular to a decomposition type soil sample collector.

Background technique

Soil sampling refers to the method of collecting soil samples, including the arrangement of samples and sampling techniques. Most of the existing soil sampling methods are to insert the soil sampler into the detection area to a certain depth and then sample. The most commonly used soil sampling tool is the soil drill, which has two types of manual operation and mechanical operation. Generally, small soil samplers are mostly manual. The way. When collecting soil samples at different depths at different locations, since the head of the existing soil sampler is inserted into the soil to a certain depth, the soil in the sampler is the soil from the surface layer to the deep layer. The length of the soil sampler is used to judge the soil at different depths, which leads to human errors in the collection depth and sampling results, which in turn affects the analysis results of the soil quality in the detection area, and such an insertion soil sampling method is not representative and cannot be taken separately. soil to a certain depth.

After retrieval, the patent No. CN114047027A discloses a soil collection device for agricultural ecological management, including the collection device shell, and also includes: telescopic assembly, depth control assembly, rotating assembly, sampling assembly and sampling cylinder, the telescopic assembly is used The telescopic assembly is used to drive the sampling assembly to expand and contract, and the telescopic assembly is also used to drive the rotating assembly to rotate. The rotating assembly is used to drive the sampling assembly to rotate. The depth control assembly controls the soil sampling depth by controlling the telescopic stroke of the telescopic assembly. control. The above-mentioned patents have the following disadvantages in the soil sampling process: after the sampling cylinder in the sampling component is inserted into the soil, the sampling cylinder will directly carry the surface soil to move, and the surface soil will fill the sampling cylinder. When the sampling cylinder extends into the deep soil Finally, the deep soil will not be able to enter the sampling cylinder, so that the collection of soil at a certain depth cannot be completed.
