Deep soil sampler for soil texture detection

Abstract

The invention discloses a deep soil sampler for soil texture detection. The deep soil sampler comprises a mounting base. A screw rod is connected in the middle part of the mounting base through a bearing; a sampling cylinder is connected on the screw rod in a threaded mode; a drilling cylinder is connected on the lower end part of the sampling cylinder in a threaded mode; spiral teeth are arrangedon the outer side of the drilling barrel; supporting plates are fixedly mounted on the front and the back of the the upper end surface of the mounting base; a hand rocker is connected on each supporting plate through a bearing; a turbine fixedly sleeves the middle of the hand rocker; first connecting rods are fixedly installed at the left lower end and the right lower end of the mounting base; second connecting rods are movably inserted in the inner cavities of the first connecting rods; second limiting blocks are fixedly inserted in the middle of the outer side faces of the second connectingrods; and the left end and the right end of the second limiting blocks are symmetrically sleeved with first limiting blocks. The deep soil sampler for soil texture detection is time-saving and labor-saving and improves the working efficiency of sampling personnel and brings great convenience to soil remediation work.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a deep soil sampler for soil quality testing. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three types: physical, chemical and biological. method, since the 1980s, many countries in the world, especially developed countries, have formulated and carried out contaminated soil treatment and restoration plans, and thus formed a new soil restoration industry; in the process of soil restoration, it is necessary to treat The repaired soil was sampled for testing. At present, when sampling soil, most of them use ordinary manual samplers for manual sampling. However, the sampling efficiency of this sampling method i...

Problems solved by technology

At present, when sampling soil, most of them use ordinary manual samplers for manual sampling. However, the sampling efficiency of this sampling method is low, and sampling is very laborious. It takes a lot of working time for the sampling personnel, increases the workload of the sampling personnel, reduces the working efficiency of the sampling personnel, and cannot realize fast and convenient sampling, which brings great inconvenience to people's soil restoration work
