Portable soil collecting device for geological survey and soil collecting method

Abstract

The invention discloses a portable soil collecting device for geological investigation and a soil collecting method, and relates to the technical field of soil collecting devices, in particular to the portable soil collecting device for geological investigation, which comprises a connecting disc and a mounting base body, and a fixing frame is fixedly mounted on the front surface of the mounting base body; and a driving motor is fixedly mounted on the lower side of the right surface of the fixed frame. According to the portable soil sampling device for geological exploration and the soil sampling method, a driving gear can rotate by starting a driving motor, so that a driving chain is driven, a driving rod can be driven by using the driving chain, then sampling operation of a sampler is realized, and a sampled sample enters an inner cavity of a sampling box through a guide-in pipe, so that the sampling efficiency is improved; according to the automatic sampling device, the functions of centralized automatic sampling and automatic collection are effectively achieved, full automation is achieved, the sampling efficiency is greatly improved, the sampling depth can be controlled by controlling the driving time of the driving chain, and the sampling depth can be adjusted at will.

Description

technical field [0001] The invention relates to the technical field of soil mining devices, in particular to a portable soil mining device and soil mining method for geological survey. Background technique [0002] In recent years, with the rapid development of economy and society, the degradation of cultivated land soil in my country has accelerated, and desertification, acidification, barrenness and scarcity have become increasingly serious. It is difficult to return agricultural and forestry waste resources to farmland, and problems such as reduction of cultivated land and insufficient land fertility have all emerged. It will pose a threat to food production, so the soil testing and sampling device can monitor soil changes in a timely and effective manner, and present real-time data to people so that people can take corresponding countermeasures, which reduces the labor pressure of people to a certain extent and brings people Here comes the convenience. [0003] At present...

AI Technical Summary

Problems solved by technology

[0003] At present, spiral samplers are usually used in the market, which requires two steps of sampling box collection, which will waste a lot of time. At present, there is no sampling device that integrates automatic sampling and automatic collection. When the moisture content of the sampled soil is very large, the soil It may be stuck on the sampler, and it is very difficult for post-workers to clean it up. Because the overall structure of the sampler is tight, it is not convenient to protect and repair the driving structure in the sampling device. Because samples at different depths have different research properties, so The ability to flexibly control the depth of sampling is also an urgent need for existing samplers. In view of this, a portable soil mining device and soil mining method for geological exploration are proposed here to solve the above problems
