Layered soil sampling device for soil detection

Abstract

The invention relates to the field of soil sampling devices for soil detection, in particular to a layered soil sampling device for soil detection, which comprises a sampling structure, a treading plate, a telescopic structure, a driving structure, a transmission structure, a guide structure and a cleaning structure, the telescopic structure used for adjusting the sampling depth is arranged on thesampling structure used for sampling soil, so that the distance between the sampling structure and the treading plate is conveniently adjusted through the telescopic structure, the sampling depth ofthe soil is conveniently and quickly adjusted, and the soil at different depths at the same position is conveniently sampled; the cleaning structure is in sliding connection with the sampling structure; the cleaning structure is driven by the transmission structure to preliminarily shovel soil on the side wall of the sampling structure; soil on the side wall of the sampling structure is effectively prevented from influencing the sampling accuracy, then the soil in the sampling structure is completely cleaned through the cleaning structure, meanwhile, the soil is effectively prevented from adhering to the cleaning structure, and then the sampling efficiency and quality of a soil sample are greatly improved.

Description

technical field [0001] The invention relates to the field of soil-taking devices for soil testing, in particular to a layered soil-taking device for soil testing. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic substances, water, air, microorganisms, etc., and can grow plants; soil is made of minerals, animals and plants, and microbial residues organic matter, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus and other components produced by body decomposition; soil sampling refers to the method of collecting soil samples, and then the collected soil is analyzed. Detect, and then treat the soil in a timely manner according to the collected soil data. [0003] However, when collecting soil with low hardness, the traditional method is to collect by excavation, and the soil at different depths is stored i...

AI Technical Summary

Problems solved by technology

[0003] However, when collecting soil with low hardness, the traditional method is to collect by excavation. The soil excavated at different depths is stored in different sampling tubes, which has poor operational flexibility and is likely to cause the upper layer to be damaged during the excavation process. The soil falls into the bottom layer, which affects the quality of sample collection, and it is not convenient to accurately and quickly sample soil at different depths at the same location. The excavation range will be large, and the vegetation near the excavation will be destroyed. When the resistance is high, it is easy to stick to the excavation tool, and the cleaning tool is not convenient and quick enough
