Description
Technical Field
The invention belongs to the field of soil collection equipment, and particularly relates to a sampling device 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 exceeding rate of the national soil is 16.1%, wherein the slightly polluted point, the severely polluted point and the heavily polluted point 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 essential tools for collecting soil samples, the quality of sampling determines the quality of sampling, and the quality 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 for observing the profile characteristics in the soil layer about 1 m; 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 widespread use. 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 loose surface soil sampling rate is low. The low sampling rate of the surface soil not only provides challenges for testing the physicochemical properties of the soil, but also causes errors in the judgment of the pollution depth. If the surface soil sample is independently collected, a new sampling device is additionally added, and the field work efficiency is influenced.
