Coal mine dust sampler device

Abstract

The invention discloses a coal mine dust sampler device. The coal mine dust sampler device comprises a box body, wherein support legs are symmetrically arranged at both sides of the lower end of the box body; a support sleeve is slidably sheathed at the lower end of each support leg; a support block is arranged at the lower end of each support sleeve; a buffer spring is arranged in each support sleeve, and is used for fixedly connecting the corresponding support sleeve and support leg. The coal mine dust sampler device has the advantages that by arranging the buffer mechanism, the anti-vibration property of the device is effectively improved; by arranging a movable bottom plate at the bottom part of the interior of the box body in a movably manner, the right end of the movable bottom plateis connected with a movable sealing plate, the movable sealing plate is provided with a material fetching port at the right side of the box body, a sealing gasket is arranged between the movable sealing plate and the box body, a pull ring is arranged at the right side of the movable sealing plate, limiting blocks are symmetrically arranged at both sides of the upper end of the movable bottom plate, and a clamp groove is formed between the limiting blocks; the detection error is decreased, the sampling accuracy is improved, and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of coal mine dust sampling and collection, in particular to a coal mine dust sampler device. Background technique [0002] As the intensity of coal mine mining increases, the amount of dust in the mining face also increases. A large amount of dust directly endangers the health of underground miners, and the risk of dust explosions also increases. Accurate control of underground mining The degree of dust dispersion in the working face is an important means to avoid the harm of underground dust. [0003] Dust dispersion is an important monitoring index parameter in downhole, and the authenticity of the detection results is very important. The main factor that can affect the detection results of dust dispersion comes from the dust collection process. The most commonly used dust collection method at this stage is the hanging pan method. Hang a sampling pan near the roof of the roadway, place sampling plates on ...

AI Technical Summary

Problems solved by technology

That is to say, for the dust collected by traditional methods, the authenticity of the dust dispersion degree obtained by the detection is highly variable, and cannot truly reflect the distribution law of the dust dispersion degree of the mining work, so the risk of underground operations is correspondingly increased. sex
