Description

A soil borrowing device for soil investigation

technical field

The utility model relates to the technical field of soil investigation, in particular to a soil borrowing device for soil investigation.

Background technique

Soil survey is a basic method to study soil in the field. Guided by the theory of soil geography, it conducts research and judgment on soil evolution, classification and distribution, fertility changes and utilization improvement through observation, description and comprehensive analysis and comparison of soil profile and its surrounding environment. It is used to describe the soil characteristics of a certain area, classify the soil according to the standard soil classification system, draw a soil map, and finally predict the soil behavior. The whole process of mapping is a basic work and means to understand and study soil. Through investigation, we can understand the general form, formation and evolution process of soil, and find out soil types and their distribution laws. Find out the quantity and quality of soil resources, and provide scientific basis for the study of soil classification, rational planning, utilization, improvement, protection and management of soil resources. Generally, in soil surveys, soil sampling devices are required to be used for soil sampling.

However, most of the soil borrowing devices currently on the market have relatively simple functions and are very inconvenient to use. When the traditional soil borrowing device is used, the soil borrowing device is usually inserted into the soil by manpower, and then the soil borrowing device is pulled out. , the sampled soil will be installed in the earth borrower. Since the earth borrower is inserted into the soil by manpower, it takes a lot of physical strength and reduces the work efficiency. Moreover, when the earth borrower is continuously inserted into the soil, the earth extractor will also be inserted into the soil. Contains topsoil, which may affect the accuracy of soil surveys.
