Description

Detachable Soil Sampling Device

technical field

The utility model relates to the technical field of tools used for soil sampling, in particular to a detachable soil sampling device.

Background technique

There are many types of soil samplers or soil sampling devices; small shovels can be used when collecting surface soil samples in agricultural land or wasteland; ring knives can be used to study general physical properties of soil, such as soil bulk density, porosity, and water-holding characteristics. 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. But in the prior art, the most commonly used sampling tool is an earth drill at present, and the earth drill is divided into two types of manual operation and mechanical operation. There are many types of soil drills that are manually operated. There are short-handled soil drills for collecting shallow soil samples, and screw-head soil drills that can observe the internal profile characteristics of the soil layer about 1 meter away. The latter saves effort in entering the soil and is especially suitable for observing groundwater level changes , but the amount of soil samples collected is small. When collecting soil samples for chemical analysis or physical analysis that does not require undisturbed soil, an open-ended soil auger is used, and when collecting undisturbed soil samples that do not destroy the structure or shape of the soil, a sleeve-type auger is used; and mechanical soil augers Driven by the motor, the drill body enters the soil at a certain depth, then the soil column is lifted up, placed flat for observation, and cut and sampled as required. The diameter of the soil column can be controlled with drill bodies of different diameters, such as 5 cm, 10 cm or thicker. However, in the current sampling device, if the soil with high humidity is required, it has the disadvantages that it is difficult to sample, and the soil is not easy to take out in the device after sampling.
