Efficient screw-in soil sampling device

Abstract

The invention discloses an efficient screw-in soil sampling device. The efficient rotary soil sampling device comprises a bracket and a sampling barrel, wherein a moving rod is arranged in the sampling barrel; the left side of the moving rod is fixedly connected with a pulling tray; the tail end of the right side of the moving rod is fixedly connected with a moving block; the moving block is pressed against a fixed block; the left side of the fixed block is fixedly connected with a sampling pipe; a sliding plate is arranged below the sampling pipe; a sample box is arranged below the sliding plate; the sample box is provided with a plurality of independent sample grids. A screw-in driving device is provided, so that a sampling depth can be reached accurately, and the sampling accuracy is increased; the sampling barrel is provided to obtain soil samples at different depths by one-time perforation, and the sampling efficiency is increased; the rotary sample box which is provided with the independent sample grids is provided for separating and storing soil samples, so that mutual pollution among the soil samples is avoided, the samples are prevented from falling off at the same time, the sample quantity is ensured, and sampling demands are satisfied.

Description

technical field [0001] The invention relates to the field of soil collection, in particular to a high-efficiency screw-in soil sampling device. Background technique [0002] There are many types of soil samplers. A small shovel can be used to collect surface soil samples from farmland or wasteland. To study the general physical properties of soil, such as soil bulk density, porosity and water holding properties, etc., ring cutters can be used. The ring knife is a cylinder with openings at both ends and a blade at the bottom. The height and diameter of the cylinder are about 5 cm. The most commonly used sampling tool is the earth auger. There are two types of soil drills: manual operation and mechanical operation. There are many types of soil augers that are manually operated. There are short-handled soil augers for collecting shallow soil samples, and screw-head soil augers for observing the internal profile characteristics of the soil layer about 1 meter away. However,...

Problems solved by technology

[0003] Traditional manual sampling is time-consuming and labor-intensive. It is difficult to sample deep soil samples. During the sampling process, it is difficult to ensure that deep soil samples are not contaminated with soil from other depths, resulting in large deviations in test data. When taking out the tool, the soil often falls, resulting in insufficient samples or representativeness of the method. For soil samples at different depths, multiple sampling is required, which wastes time and physical strength.
