Soil sampling device facilitating screening and removing of stone in soil

Abstract

The invention discloses a soil sampling device which is convenient for screening and removing stones in sample soil. A driving machine is arranged in the middle of the bottom of the transverse connecting plate, a PLC controller is installed on the left side of the device body, a screening plate is provided inside the first screening device, and a through hole is provided on the screening plate, so Balance bars are provided on both sides of the movable disk, and clamping pieces are provided on both sides of the port of the screening plate, and a spring is connected between the clamping piece and the first screening device. Inside the tray is mounted a second collection tube. The soil sampling device, which is convenient for screening and removing stones in the sample soil, can screen the sample soil to screen out the stones in the soil, and the device can separately screen dry soil and rare earth, which is convenient for users to Soil sampling for testing.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a soil sampling device which is convenient for screening and removing stones in sample soil. Background technique [0002] Soil environment detection refers to determining the environmental quality (or pollution degree) and its change trend through the determination of representative values ​​of factors affecting soil environmental quality. What we usually call soil detection refers to soil environment detection, which generally includes point sampling , sample preparation, analysis method, result characterization, data statistics and quality evaluation and other technical contents, while soil testing requires the use of sampling and testing devices. There are still some problems in the current soil detection device, for example, it is inconvenient to screen out the soil and rocks in the soil, and the current soil screening device cannot effectively screen dry soi...
