Sampling device for modern agricultural soil detection

Abstract

The invention discloses a sampling device for modern agricultural soil detection. The sampling device comprises a sampling device body, wherein at least three groups of first electric push rods are symmetrically arranged on the two sides of the inner wall of the sampling device body; a soil cutting plate is fixedly connected with one ends, far away from the inner wall of the sampling device body,of the at least three groups of first electric push rods; at least three groups of second electric push rods are arranged on the other side of the inner wall of the sampling device body; one ends of the at least three groups of second electric push rods penetrate through an opening and are fixedly connected with a push plate at the end parts; a piston is arranged inside a soil storage cavity; a piston rod is fixedly connected with the upper surface of the piston; and the other end of the piston rod penetrates through the sampling device body and is provided with a hand cross bar. The samplingdevice drives the soil cutting plate by means of the first electric push rods to separate soil at different depths from one another, realizes layered sampling on the soil at different depths, drives apush rod by means of the second electric push rods to push out cut soil, and is convenient to take out soil in bulk.

Description

technical field [0001] The invention belongs to the technical field of soil sampling, in particular to a sampling device for modern agricultural soil detection. Background technique [0002] The collection of soil samples is the foundation of soil scientific research and geological survey, and provides a material basis for the determination of the physical and chemical properties of soil samples. There are many methods for soil sampling. [0003] In the prior art, a drill pipe is generally used for sampling. When the drill pipe is drilled into the ground, the soil forms a soil column in the drill pipe, and the entire soil column is taken out for analysis. The above-mentioned sampling drill pipe cannot be used for different sampling layers and depths. After the soil is obtained, the soil cannot be automatically discharged from the device, and it is inconvenient to take out the soil. Contents of the invention [0004] The purpose of the present invention is to provide a sam...

[0003] In the prior art, a drill pipe is generally used for sampling. When the drill pipe is drilled into the ground, the soil forms a soil column in the drill pipe, and the entire soil column is taken out for analysis. The above-mentioned sampling drill pipe cannot distinguish between different sampling layers and depths. Differentiate the samples, and at the same time, after the soil is obtained, the soil cannot be automatically discharged from the device, and the removal of the soil is inconvenient
