Portable sampling device for coal mine detection

Abstract

The invention discloses a portable sampling device for coal mine detection. The sampling device comprises a shell and a sampling drill; a bearing is arranged at the top end of the shell, and a supportrod is arranged in the bearing; a left side of a drilling rod is connected with a meter counter, and a tail end of the drilling rod is connected with a digging drill; an expansion link is arranged atthe left side of the digging drill, and the tail end of the expansion link is connected with a rotating plate; the sampling drill is arranged at a right side of a wheel, and an upper side of the sampling drill is connected with a sampling rod; by arranging the meter counter, a roller on the meter counter can be driven to move so as to record the downward extending depth of the drilling rod and the sampling rod when the drilling rod and the sampling rod move downwards, thereby guaranteeing that the sampling depth is more accurate, and the sampling work is more convenient; by arranging the liftable wheel, the sampling work can be performed by continuously moving the location of the device in the coal mine detection, the wheel can lift or decline by rotating a screwed pipe, so that the movement and the fixation of the device are relatively simple.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a portable sampling device for coal mine detection. Background technique [0002] Coal seam sampling is also called coal seam sampling. According to certain specifications and requirements, a small part of representative samples are taken from the coal seam for analysis, testing and identification. The purpose of coal seam sampling is to pass the test of coal samples and physical tests. The obtained data are used to determine the coal types, coal quality characteristics and their changing laws and coal technological properties of mineable coal seams in mining areas or mine fields, so as to correctly evaluate coal quality, determine the processing technical characteristics of coal and the direction of industrial utilization. To provide reliable coal quality data for the development and rational utilization of resources. [0003] During the use of coal mine sampling devic...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a portable sampling device for coal mine detection, to solve the problem of inaccurate control of sampling depth and inaccurate control of the sampling depth during the use of the coal mine sampling device proposed in the background technology mentioned above. If the soil is not treated, it is easy to cause the hole to be blocked. The movement and fixation of the whole device are inconvenient. A large amount of dust will be generated during the drilling process, and a large amount of impurities are easily mixed in the sample.
