Abstract

The invention provides a manual rotary soil columnar sample sampling device. The manual rotary soil columnar sample sampling device comprises a rack, a soil sampling rod, a soil sampling drill bit and a manual driving mechanism, a limiting structure and a manual driving mechanism are arranged on the rack; the manual driving mechanism comprises a rocker, a first bevel gear, a first bearing, a second bevel gear and a second bearing; internal threads are arranged on the second bevel gear and are in threaded connection with the soil sampling rod, so that rotation of the rocker is converted into vertical movement of the soil sampling rod to drive the soil sampling drill bit to enter soil for sampling. Compared with the prior art, the manual rotation soil columnar sample sampling device provided by the invention has the advantages that the sampling drill bit downwards enters the soil by utilizing manual rotation force, the sampling drill bit reversely rotates to take out the soil columnar sample, and the sampling device is simple in structure, convenient to carry and time-saving and labor-saving in sampling. The graduated scale is arranged on the soil sampling rod and used for calculating the soil sampling depth, and accurate sampling is facilitated.

Description

technical field [0001] The invention relates to the technical field of soil sampling equipment, in particular to a manual rotating soil columnar sample sampling device. Background technique [0002] Soil is a layer of loose material covering the earth's surface, composed of various granular minerals, organic matter and organisms. It can not only provide nutrients for biological growth, but also record the development and evolution information of the earth. Since the formation of science, a large number of scientific researchers have conducted in-depth research on soil. The study found that the soil column samples not only recorded the information of the migration and transformation of soil nutrients, but also recorded the development and evolution of the earth's ecosystem, such as earth evolution, human activities, and climate change, as well as the information of the development and evolution of the universe. Therefore, the analysis of soil has always been a hot research t...
