Zusammenfassung: | The utility model discloses a novel quick drilling cutting quantity collector. The drilling device comprises a drilling device body and a sampler, the drilling device body comprises a drilling deviceshell and a drill rod, the drill rod penetrates through the center of the drilling device shell, the sampler is of a hollow structure, the drilling device shell is communicated with the sampler, the sampler is in butt joint with a collecting bag, and drilling cuttings generated when the drill rod drills enter the collecting bag through the drilling device shell and the sampler. The influence of wind on drilling cuttings collection and missing of the drilling cuttings amount during drilling can be effectively avoided, the drilling cuttings amount can be tested more conveniently, accurately andeffectively, effective use of a coal cuttings index method is powerfully guaranteed, and therefore the working face outburst prediction accuracy is improved. The safety of production operation is improved, and the dust amount |
