(2)Discharge barrel stretches into inside blasthole;The coiled stemming that diameter is slightly less than feeding cylinder diameter is chosen, is put into along charging nozzle,
Coiled stemming falls by dead weight, and control centrifugal fan rotary speed is matched with stemming falling speed, so that stemming is cut into tiny
Wet piece;
(3)Wet piece of stemming pours at a high speed blasthole, reaches under centrifugal fan centrifugal action and outlet passageway gas pressure after cutting
The purpose of blasthole is blocked to high solidity;
(4)After the completion of blasthole plugging construction, connection bolt is removed, using water or pressure-air descaling machine intracavitary portion, when necessary may be used
Removal handle provides cleaning facility.
Present invention utilizes flabellum cutting, centrifugation thoughts, have the following advantages:
(1)It selects compressed air as power source, reduces electric leakage, the generation of explosive accident during blast hole stemming, ensure to apply
Work safety;
(2)The ante-chamber and back cavity of ramming machine are bolted, easy to disassemble, cleaning and repair internal structure;
(3)Clog that blasthole is convenient and efficient, it is dynamic that the present invention has combined centrifugal fan and air motor outlet passageway provides jointly
Power, percussion can significantly improve stemming self compacting ability, and blast hole stemming work disposably can be completed, reduce labor intensity,
Improve construction efficiency;
(4)It is simple in structure, it occupies little space, it is easy to carry, adapt to the blast hole stemming work of complex condition.
