a soil sampler

Abstract

The invention discloses a soil sampler, comprising a first sampling drill bit, a second sampling drill bit, a first slot, a second slot, a first connecting rod, a second connecting rod, a first handle, a second handle, a first A fastener, a second fastener, a first connecting strip and a second connecting strip; first slots are arranged on both sides of the first sampling drill bit, and the bottom end of the first sampling drill bit is connected to one end of the first connecting rod connected, and the first sampling bit and the first connecting rod are coaxial; the two sides of the second sampling bit are provided with second slots; the bottom end of the second sampling bit is connected to one end of the second connecting rod, and the second sampling The drill bit is coaxial with the second connecting rod. In the present invention, two semicircle-arc sampling drill bits are inserted into the soil successively for sample collection, and the sampling drill bits are easy to press down in the soil; the vertical pressure on the soil sample is small during the pressing down process, and it is easy to keep the original state of the soil; The arc sampling drill bit can be separated directly, which is convenient for taking out the soil sample from the sampling head, and effectively avoids disturbing the soil sample again.

Description

technical field [0001] The invention relates to a soil sample collecting device, which is suitable for collecting various types of soil samples requiring little disturbance to the original properties of the soil. Background technique [0002] Soil sample collection and analysis of its physical and chemical properties are widely used in scientific research and industrial and agricultural production practices in environmental science, geography, ecology, agronomy and other disciplines. The quality of soil sample collection directly affects the results of subsequent physical and chemical property analysis, so it is required to keep the original soil properties as much as possible during the soil sample collection process. [0003] In addition to destructive excavation sampling, currently commonly used soil samplers are inserted into the soil through the drill bit, and the friction between the drill bit and the soil is used to bring out a certain depth of soil to achieve sample ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the defects of the prior art, the object of the present invention is to provide a soil sampler, which aims to solve the problems in the prior art that the compaction effect of the soil sample is obvious, the applicable soil type is limited, and the sample is difficult to take out due to the use of a circular tube sampling drill bit. Problems and due to the use of circular groove drills, it is difficult to locate accurately and the samples are easy to mix
