矿用钻屑法检测煤粉取样器制造技术

本实用新型专利技术公开了一种矿用钻屑法检测煤粉取样器，包括接粉漏斗，所述接粉漏斗的上部边缘连接多个固定链，所述接粉漏斗上部设有挡矸筛网；所述接粉漏斗的下部连接取粉管。所述挡矸筛网通过活折页焊接在漏斗上。所述接粉漏斗与取样管通过螺栓连接。所述取粉管的下部卡接塑料袋。所述取粉管下端设置可缩放的管卡。接粉漏斗在固定链的作用下可以紧密贴实巷帮，钻杆钻进时排出的煤粉可以最大程度地通过接粉漏斗进入取粉管，杜绝了煤粉收集不充分的现象。同时，可以避免大块煤或矸石通过取粉管进入煤粉内，取消了人为挑出大块矸石环节，简化了钻屑法检测流程，提高了煤粉取样的精确度和可操作性，为更好、更精确地判定冲击危险程度提供了有力硬件支持。

Detection of coal dust sampler by drilling cuttings

The utility model discloses a coal powder sampler for detecting coal powder by mining drilling cuttings method, which comprises a powder receiving funnel, the upper edge of the powder receiving funnel is connected with a plurality of fixed chains, the upper part of the powder receiving funnel is provided with a gangue screen, and the lower part of the powder receiving funnel is connected with a powder taking pipe. The gangue retaining screen is welded on the funnel through the movable hinge. The powder receiving funnel and the sampling pipe are connected by bolts. The lower part of the powder taking pipe is clamped with a plastic bag. The lower end of the powder taking pipe is provided with a scalable pipe clamp. Under the action of the fixed chain, the powder receiving funnel can be closely attached to the roadway side. The pulverized coal discharged from the drill pipe during drilling can enter the powder taking pipe through the powder receiving funnel to the greatest extent, thus eliminating the phenomenon of insufficient collection of pulverized coal. At the same time, it can avoid the large coal or gangue entering the coal powder through the powder pipe, cancel the artificial picking out the large gangue link, simplify the detection process of drilling cuttings method, improve the accuracy and operability of the coal powder sampling, and provide strong hardware support for better and more accurate determination of the impact risk degree.
