Soil sampling device for environmental monitoring capable of detecting soil of different depths

Abstract

The invention discloses a soil sampling device for environmental monitoring which can detect soil at different depths, which comprises a sampling device main body, a rotating rod, a pushing rod, a cutting knife, a positioning hole and a fixing sleeve, and a sampling cylinder is arranged on the sampling device main body , and the two sides of the upper end of the sampling cylinder are connected with the grip rod, the rotating rod is arranged in the side wall of the sampling cylinder through the bearing, and the outer side of the sampling cylinder is set with a positioning plate, and the push rod is arranged inside the sampling cylinder , and the lower part of the push rod is connected with the push block, the cutting knife is arranged on the bottom end of the rotating rod through the cutting edge, and the upper end of the rotating rod is connected with the rotating handle, the fixed sleeve is arranged above the positioning plate, and The inside of the fixed sleeve is connected with the positioning rod through the compression spring and the fixed block. The soil sampling device for environmental monitoring capable of testing soil at different depths is provided with a positioning plate outside the sampling cylinder, which is beneficial to sampling and testing soil at different depths.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a soil sampling device for environmental monitoring that can detect soil at different depths. Background technique [0002] The growth of plants requires a good soil environment. Different plants or the same plant have different requirements for the soil environment at different growth stages. By detecting the changes in temperature, moisture content, and pH in the soil, it can help people understand the basic situation of the soil in time. Changes in the soil can determine whether the growth of plants in the soil urgently needs water and the addition of acid-base fertilizers. The timely acquisition of environmental temperature change information for plant growth can prevent the damage to plants caused by sudden cooling and warming of the weather, thereby ensuring that the plants are in a relatively stable environment. Grow in an ideal soil environment to increas...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a soil sampling device for environmental monitoring that can detect soils at different depths, so as to solve the problem that the existing soil sampling device for environmental monitoring for soil detection proposed in the background technology does not have a positioning function and does not It is convenient for users to sample soil at different depths, and when the sampling device is taken out, the soil is too firmly connected to the ground soil, and the soil is prone to slipping out of the sampling cylinder, which is not conducive to the problem of soil sampling
