Soil sample collecting device

Abstract

The invention discloses a soil sample collecting device. The soil sample collecting device comprises a spiral rod, a sampling device arranged at the end part of the spiral rod and used for collecting the soil sample, and a driving device for driving the spiral rod to rotate; the driving rod is connected with a control device for controlling the driving device, and a positioning mechanism for positioning the coordinate of the soil sample position is arranged on the driving device; the outer part of the spiral rod is provided with a sleeve cylinder for mounting the supporting device. The soil sample collecting device is simple in structure, good in using effect, and easy to operate; by directly collecting the collected soil sample in a storage cylinder, the continuity of sampling is increased, and the physical change of the soil sample in the air is prevented by sealing the soil sample, thereby benefiting the subsequent experimental analysis of the soil sample; moreover, a level gauge is arranged at the upper part of the horizontal rotating drill rig, so that the accurate control of perpendicularity of the sampling device is guaranteed during the sampling process, the collected soil sample is marked directly through the positioning mechanism, the labeling accuracy of the soil sample is guaranteed, and the labor force is saved.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a soil sample collection device. Background technique [0002] In recent years, with the rapid development of the economy, the domestic soil environment has been polluted to varying degrees, which threatens the development and utilization of land resources, affects the development of cities and people's health. Therefore, the investigation and monitoring of soil environmental quality is on the right track. After collecting soil samples, analyzing their basic physical and chemical properties and the content of pollutants has important reference value for environmental risk assessment. [0003] At present, the collection of soil samples is still dominated by manual excavation. The principle of a small number of samplers is basically the same as that of the "Luoyang shovel", that is, the ground where the soil samples are to be collected is hit by a vert...

AI Technical Summary

Problems solved by technology

In actual operation, there are the following problems: 1. For the collection of soil samples from manual excavation sections, the sampling depth is generally controlled more accurately, but the required labor is intensive, and the excavation section has a huge disturbance to the surface, which is easy to damage the surface vegetation and cause water and soil pollution. 2. A small number of samplers will tamp the soil sample due to the vertical external force, which will affect the physical properties of the soil sample itself, especially the porosity, which will adversely affect the follow-up experimental analysis. The direction is difficult to control accurately, and the depth of soil sample collection is prone to deviation; 3. It is difficult to clean the samp
