Description
Technical Field
The invention belongs to the field of soil sample collection equipment, and particularly relates to a sampling rotary drum for spirally propelling soil.
Background
With the continuous acceleration of urbanization and industrialization and the frequent interference of human activities, the problem of soil pollution is more serious. In 2014, 17 th month, the national soil pollution condition survey bulletin was released by the ministry of environmental protection and the ministry of national resources in a united manner, and the results of the survey show that: the total point position exceeding rate of the soil in China is 16.1%, wherein the slightly polluted point position, the severely polluted point position and the severely polluted point position are respectively 11.2%, 2.3%, 1.5% and 1.1%, the soil environment condition is totally unobtrusive, and the pollution treatment work is urgent.
The components and concentration of soil pollutants are the basic premise for formulating the treatment measures of soil pollution, and the soil sample collection and analysis are the basic means for acquiring the physiological and biochemical properties and the component characteristics of soil. The soil sampler is one of necessary tools for collecting soil samples, the sampling quality is determined by the sampling performance, and the sampling performance is closely related to the accuracy and reliability of finally obtained data.
There are many types of soil samplers. Different samplers are selected according to different sampling analysis purposes. Collecting a surface soil sample of the farm land or the wasteland, wherein a small iron shovel can be used; the general physical properties of soil, such as soil volume weight, porosity, water holding property and the like, can be researched, and a cutting ring can be utilized; collecting shallow soil samples and selecting short-handle soil drills; screw head earth auger can be selected by observing the profile characteristics in about 1 m soil layer; when collecting a soil sample for chemical analysis or physical analysis without undisturbed soil, using an open-type soil drill; collecting an undisturbed soil sample which does not damage the structure or the shape of the soil, and using a sleeve type soil drill; soil sample collection in contaminated site surveys often employs a sampling instrument that directly propels the drilling machine.
Methods for soil sampling using direct propulsion techniques have found wide application. However, in the process of directly pushing downwards, the friction resistance between the drill bit and the soil is large, so that the drill bit is obliquely pushed into the soil, and the sampling rate of loose surface soil is low; in the sampling process, the soil depth needs to be measured for multiple times, and the soil collection steps are complicated and time-consuming. If the surface soil sample is independently collected, a new sampling device is additionally added, and the field work efficiency is influenced.
