Field in-situ soil column electric sampling device

Abstract

The invention relates to the technical field of soil sampling, in particular to a field in-situ soil column electric sampling device which comprises a mounting plate, a motor is arranged at the top of the mounting plate, a hollow drill rod is connected to the bottom of the mounting plate through a bearing seat, and the output end of the motor penetrates through the mounting plate to be connected with the hollow drill rod. A soil unloading disc is arranged at the top of the inner side of the hollow drill rod, a threaded rod extending out of the outer side of the hollow drill rod is arranged on the outer circumferential wall of the soil unloading disc, an annular support is arranged at the top of the soil unloading disc, and sweeping brushes are evenly arranged on the outer side of the annular support. Soil sampling work is carried out through the motor and the hollow drill rod, the structure is simple, convenience and rapidness are achieved, the original mode that samples are collected in field peat land or clay land purely through manpower is replaced, efficiency is improved, and the problem that time and labor are consumed in field sampling work is greatly solved.

Description

Technical field [0001] The present invention relates to the field of soil sampling techniques, and is specifically a field in situ soil column electric sampling device. Background technique [0002] The soil column experiment is an essential means for research on agriculture, forestry, water conservancy, environment and other fields. Through the earth column experiment, the migration law and mechanism of water, pollutants in the soil can be studied indoors. Therefore, in the field investigation work It is often necessary to use the soil acquisition device to sample and collect soils. [0003] The existing urbanized soil diamonds are manual operations, which are not only more effective in the wild peat or sticky land collection samples, but also for deeper soils. Especially in the high altitude area, it is more greatly tested to manpower, and the artificial pressure relief is limited by the pressure of human application, limiting its sampling depth and sampling diameter, and it is...

AI Technical Summary

Problems solved by technology

[0003] Most of the soil drills used in the existing collection operation methods are manually operated. It is not only laborious and time-consuming to collect samples in peatland or clay soil in the field purely by manpower, but also cannot be used for deep soil collection. Especially in high-altitude areas, it is a great test for manpower, and because of the limited pressure exerted by humans, the artificial pressure soil drill restricts its sampling depth and sampling diameter, and it is difficult to ensure that it is completely vertical, and it will appear during the sampling process. Skew, which may cause extrusion disturbance of the soil column, thus affecting the quality of the sample taken out
