Coal mining sampling device

Abstract

The invention belongs to the field of coal mining sampling and relates to a coal mining sampling device which comprises a main body, a moving mechanism, a storage mechanism, a material taking mechanism, a pulling mechanism and a heat dissipation mechanism. the the moving mechanism is adopted, so that the turning radius can be reduced during turning, and therefore,the moving flexibility of the mainbody is improved; the interior of a coal mine can be automatically tunneled for collection and sampling through the material taking mechanism, the labor intensity of sampling personnel is reduced, and manpower is saved; through the storage mechanism, samples collected by the material taking mechanism can be conveniently collected and stored, other external coal is prevented from being mixed in the samples; through the pulling mechanism, the moving mechanism can be conveniently operated to move; the pulling mechanism can be automatically contracted and folded into the main body without external force operation, and therefore, limited working space is prevented from being occupied, the use experience of the sampling device is improved; a power part in the material taking mechanism can be cooled through the heat dissipation mechanism, and the service life of the sampling device is prolonged.

Description

technical field [0001] The invention relates to the field of coal mining sampling, in particular to a coal mining sampling device. Background technique [0002] Coal is a solid combustible mineral that was gradually formed by ancient plants buried underground through complex biochemical and physicochemical changes. Coal is hailed as black gold and the food of industry. It has been one of the main energy sources used by the human world since the eighteenth century. Since the beginning of the 21st century, although the value of coal has dropped significantly, after all, the present and the future are very long. For a period of time, coal is still one of the indispensable energy sources for our human production and life. The supply of coal is also related to the stability of the development of my country's industry and even the entire society. The issue of coal supply security is also the most important aspect of my country's energy security. important part. [0003] According ...

AI Technical Summary

Problems solved by technology

[0003] According to the different raw materials and conditions of coal formation, coal in nature can be divided into three categories, namely humic coal, residual plant coal and sapropel peat. Different qualities of coal are used in different occasions. It is a professional device for sampling coal. However, most of the traditional sampling devices are collected by hand-held auger drills, and because there are no special storage parts attached, it is easy to confuse the collected samples with other coals, resulting in inconsistent detection data. Accurate and manual sampling increases labor intensity and reduces work efficiency
