Soil sampling device with mashing function for agricultural environment-friendly detection

Abstract

The invention discloses a soil sampling device with a mashing function for agricultural environment-friendly detection. The device structurally comprises a needle cone cap, a sliding sleeve sample tube shaft frame, an insertion frame cylinder groove, an observation groove, a screw cap, an auxiliary handle and a rotating shaft grip frame, according to the invention, the sliding sleeve sample tube shaft frame matches the insertion frame cylinder groove; after the soil sampler is inserted into the soil, the built-in soil is removed in the sampling tube chamber through the cooperation of a needletip slender rod and a corrugated narrow strip rod and a needle frame traction sleeve wheel; a propeller is pulled to rotate; the needle tip slender rod and the corrugated narrow strip rod are driven to hook rhizomes and dead leaves mixed in a soil layer to form carding operation; the completeness of soil impurity removal is ensured; soil is effectively crushed into powder through the pressure of avibrating pipe in a vibrating pipe shaft seat, so that titration of reagent liquid and slice microscopic observation operation in the later period are facilitated, the purity of soil sampling and theautomatic fine adjustment cleaning effect are effectively guaranteed, the powdery mashing effect pretreatment operation during environment-friendly detection is improved, and the agricultural environment-friendly soil detection accuracy is guaranteed.

Description

technical field [0001] The invention relates to a soil sampling device for agricultural environmental protection detection with a crushing function, which belongs to the field of agriculture. Background technique [0002] Regular detection of farmland soil layer is a necessary part of agricultural environmental protection operations. It is necessary to regularly survey the restoration of soil fertility and ensure that the effective nutrients of the soil are not suitable for crop growth. The pretreatment of crop planting testing and sampling forms a detailed survey operation effect. At present Disadvantages of common technologies to be optimized include: [0003] Soil testing for agricultural and environmental protection requires inserting soil samples, which will cause the remaining roots of agricultural plants to be included in the soil layer. When testing the chemical solution, the nutrients of the roots penetrate into the soil and cause the soil to be misled. It has a lab...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a soil sampling device for agricultural environmental protection testing with a crushing function, so as to solve the need for soil sampling for agricultural environmental protection soil testing, which will cause residual rhizomes of agricultural planting plants Incorporated into the soil layer together, when the chemical solution is detected, the nutrients of the rhizome penetrate into the soil and cause the effect of misleading the soil to have a laborious effect, resulting in excessive labor consumption of a soil for subsequent agricultural planting, resulting in a decline in land labor, and Sampling detection continues to be inaccurate, and the resulting sampling deviation is not strong enough to remove the rhizomes clamped in the soil, thus affecting the regionalization data of agricultural environmental protection testing in the later period
