Labor-saving shallow-layer soil sampling device

Abstract

The invention discloses a labor-saving shallow-layer soil sampling device, which comprises a moving rod, a soil sampling driller and two driving devices. The soil sampling driller is arranged in the middle of the moving rod; the driving devices are connected to two ends of the moving rod, and simultaneously drive two ends of the moving rod to move downwards so as to drive the soil sampling drillerto move downwards to cut a soil body; the two driving devices simultaneously drive two ends of the moving rod to move upwards so as to drive the soil sampling driller to move upwards to obtain the cut soil body. The labor-saving shallow-layer soil sampling device provided by the invention is labor-saving in sampling soil, wide in sampling range, and capable of accurately setting the adopted depth; the disturbance on the sampled soil is avoided.

Description

technical field [0001] The invention relates to a shallow soil sampling device, in particular to a shallow soil sampling labor-saving device. Background technique [0002] In the fields of hydrogeology and environmental science, the collection of soil samples is often involved. The collection of soil samples depends on different depths, sampling tools and power are quite different. Generally speaking, drilling rigs are used for deep soil, which provide sampling power through machinery, and soil drills are used for shallow soil. The soil drill is simple, convenient and easy to carry. It is the first choice for field sampling work, but there are also the following problems in the sampling process: ( 1) It is relatively easy to collect the surface soil with the soil drill alone. As the depth increases, the difficulty of sampling increases, and the staff need to consume a lot of energy to achieve the goal; (2) when sampling, the staff surround the sampling point, and the Surfa...
