Description

Technical Field

[0001] The utility model relates to the field of soil sample collection equipment, in particular to a drilling sampling device. Background Art

[0002] Soil refers to a loose layer of material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals formed by weathering of rocks, organic matter produced by the decomposition of animal and plant and microbial residues, soil organisms (solid phase matter), water (liquid phase matter), air (gas phase matter), oxidized humus, etc. Solid matter includes soil minerals, organic matter and nutrients obtained by microorganisms after light inhibition and sterilization. Liquid matter mainly refers to soil water. Gas is the air existing in the pores of the soil. These three types of substances in the soil constitute a contradictory unity. They are interconnected and mutually restricted, providing the necessary living conditions for crops, and are the material basis of soil fertility. The substances in the soil can be summarized into three parts: solid part, liquid part and gas part (solid phase, liquid phase and gas phase). Soil minerals are mineral particles of different sizes (sand particles, soil particles and colloid particles) formed by weathering of rocks. There are many types of soil minerals with complex chemical composition. It directly affects the physical and chemical properties of the soil and is one of the important sources of crop nutrients. Solid soil particles composed of minerals and humus are the main body of soil, accounting for about 50% of the soil volume. The pores between solid particles are occupied by gas and water. Most of the soil gas is oxygen and nitrogen entering from the atmosphere, and a small part is carbon dioxide and water vapor produced by life activities in the soil. The water in the soil mainly enters the soil from the surface, including many dissolved substances.

[0003] Soil sampling is an important work link in the fields of engineering construction, modern agriculture, geology, water conservancy and environmental protection. Soil samples are usually divided into two categories: original soil samples and disturbed soil samples; original soil refers to soil samples that maintain natural water content and naturally formed structure. It is used to determine physical and mechanical properties such as soil bulk density, natural porosity, compression coefficient and shear strength. Original soil maintains the natural structure and water content of the soil, and is used to determine indicators such as bulk density, permeability, compression and shear strength; while the natural structure of disturbed soil samples has been disturbed, and is used for soil particle size analysis, determination of soil liquid and plastic limits, density, relative density, natural slope angle, etc. The number and specifications of the collected soil samples should be determined to meet the test items and test methods. The soil samples are required to basically maintain the original structure and water content, and should be sealed with wax in time to prevent water evaporation. They should be properly stored before use and not be subjected to shock, heat or freezing.

[0004] Different geographical locations have different soils and different hardnesses. Currently, there are various tools or equipment for soil sampling, and large-scale mechanical equipment or small tools are complete; soil drills are one of the main tools for collecting soil samples in these fields. The reliability, ease of operation and mobility of soil drills can not only reduce the workload of soil investigation and improve the efficiency of soil sampling, but also expand the adaptability of soil sampling. Domestic soil samplers mostly use direct press-in, hammer pressurized and press-in rotary types. Soil drills are mainly non-disturbance original soil drills, mechanical power drills and special soil drills... etc. And according to different usage requirements, there are also many manual or semi-manual sampling equipment or tools. However, although there are many types of soil sampling equipment at present, the various types of soil sampling equipment currently have at least the following problems:

[0005] 1. For concrete, ore, and soil with high hardness, the current equipment can complete sample collection through the drill rod, drill bit, core tube, core extractor and other components in the equipment, and it is convenient to observe the cross-section and original status of the sample; however, for soil with low hardness and easy to loosen, it is impossible to shape the sample in the hole as a whole and take it out without breaking it, resulting in the removal of the sample being mostly in the form of crushed particles and unable to be shaped, thus affecting subsequent analysis and measurement; and the soil will be scattered during the removal process;

[0006] 2. Once the current soil sampling equipment is damaged, too many parts need to be replaced, making the maintenance cost too high. Utility Model Content
