The diameter of the venthole is less than the diameter of bit shank centre bore and drilling rod centre bore.
The bit shank centre bore is threaded hole, and venthole and drilling rod centre bore are circular hole.
The bit shank, connector sleeve ontology and drilling rod constitute ladder circle cylindricality, and the outer diameter of bit shank is less than the outer of connector sleeve ontology
Diameter, the outer diameter of connector sleeve ontology are less than the outer diameter of drilling rod.
Using the utility model, during boring iron mouth, the compressed air being blown into from bit shank centre bore enters drilling rod connector sleeve
Ball sealer is blown to and blocks duct outer end by ontology venthole, and venthole is got through at this time, and compressed air is through drilling rod centre bore from drill bit
Front end is blown out, and the brill generated when to boring iron mouth is beaten object and purged.In the case of meeting compressed air and stopping suddenly, ball sealer
It is rolled down under self gravitation effect and blocks duct bottom, venthole is automatically closed, slag iron in stove is effectively prevented to pour in down a chimney
Into rock drill.
The utility model has the beneficial effects that：When efficiently avoiding compressed air during tapping outlet and stopping suddenly, stove
Interior slag iron is poured in down a chimney into inside rock drill, and the service life of tapping machine is extended, and has saved spare part expense.Three are saved by annual
Platform rock drill, every rock drill by 4.5 ten thousand yuan of calculating, year direct benefit be 13.5 ten thousand yuan.Reduce maintenance and maintenance time simultaneously
Number, reduces the labor intensity of worker, ensure that being smoothed out for operation of tapping a blast furnace.
