Description

Technical Field

[0001] The utility model belongs to the field of soil sampling machinery, and in particular relates to an integrated sampler for detecting the quality of cultivated land soil. Background Art

[0002] With the discharge of industrial waste, the indiscriminate dumping of domestic garbage and excessive fertilization by farmers, the problem of cultivated land soil pollution is becoming more and more serious. Cultivated land soil pollution will affect the quality of food and human health, and will also affect the growth of crops and the quality of crops, which is not conducive to the healthy development of agricultural production. It is necessary to test the cultivated land soil to see whether the cultivated land soil is polluted and what the main problems are, and then take reasonable measures. Before testing the cultivated land soil, it is necessary to take cultivated land soil samples and use cultivated land soil sampling equipment.

[0003] The Chinese patent with the publication number CN207528489U discloses a cracking type convenient soil sampler, including a sampler body and a pointed ring knife; the pointed ring knife is detachably mounted at the bottom of the sampler body, and large handles are arranged on both sides of the upper part of the sampler body; the sampler body includes an external circular cracking type device main pipe and two internal semicircular grooves; gaps are arranged on both sides of the circular cracking type device main pipe, and there are semicircular sampling grooves inside the cracking type sampling main pipe, and sampling groove handles are arranged on the semicircular sampling grooves, and the sampling groove handles can slide through the gaps on both sides of the circular cracking type device main pipe and be placed on the outside of the circular cracking type device main pipe. The cracking type convenient soil sampler of the utility model can not only collect a large number of soil samples efficiently and deeply, but also can conveniently take out soil samples without destroying the soil structure; and the cost is low and the sampling is fast. The development of the soil sampler of the utility model is more conducive to the collection of soil samples and the detection of soil quality.

[0004] The cracking type convenient soil sampler in the above-mentioned comparative document requires multiple sampling operations when sampling at different levels at the same sampling point, which is time-consuming and laborious. In addition, due to errors in the sampling process, the collected cultivated soil samples may be mixed with impurity soil at different levels, which has a great impact on the detection of contaminated soil and misleads the subsequent analysis to a certain extent, so that the analysis results cannot accurately reflect the actual soil quality.

[0005] In view of this, the present utility model is proposed. Utility Model Content
