Kukho iindidi ezimbini: enye ikwisixhobo sokomba esijikelezayo ngokwesiseko sokongezwa kwesixhobo sokungqubana, ikakhulu ekugrunjweni okujikelezayo, xa udibana nomaleko wengqalutye onempembelelo yokugrumba umbhobho wokugrumba oneenjongo ezimbini, ukukwazi ukuziqhelanisa ngamandla nezitrato ezahlukeneyo;Enye impembelelo kunye nesenzo esijikelezayo esidityaniswe nesixhobo sokugrumba iqula, njenge-pneumatic DTH hammer drill.I-DTH hammer drill (FIG. 5) yenziwe nge-cylinder liner kunye nepiston ehamba phezulu nangaphantsi kwi-cylinder liner.Isiphelo esisezantsi somgca we-cylinder sidibaniswe ne-drill bit, kwaye isiphelo esiphezulu sidibaniswe nombhobho wokubhobhoza ngokusebenzisa i-threaded joint.Umoya woxinzelelo oluphezulu obonelelwa yi-compressor yomoya yi-0.7 ~ 1.4 mpa ngevalve yokutshekisha ngaphezulu kwepiston, umhambisi womoya kunye ne-air inlet ngaphantsi kwepiston, kunye nokuphindaphinda kwempembelelo yepiston kutyhalwa phezulu nasezantsi njenge-700 ~ 1200. amaxesha/min, ukuze ipiston ibe nefuthe rhoqo kwi-drill bit.Ukuphucula isakhono se-drill bit ukubhola ilitye.Ngexesha elifanayo, umbhobho we-drill ujikeleza ngesantya esisezantsi se-35 ~ 60 RPM.Umoya osuka kwimingxuma ephezulu nasezantsi yepiston uqukuqela uhle uye ezantsi kwi-bit ukuze upholise isuntswana kwaye ukhuphe imingxunya engezantsi kwintloko yomthombo.Ubume be-rotary kunye nokujikeleza kakuhle inxalenye yokuhlamba ngokusisiseko iyafana naleyo ye-rotary drill enomoya ocinezelweyo, kunye ne-bit esetyenziswayo yi-tungsten carbide ball tooth bit okanye i-roller cone bit.I-pneumatic DTH i-hammer drill ingasetyenziselwa ukugrumba iMigodi enzulu kwistrata samatye aqinileyo.Isantya sokugaya siphezulu, kwaye isantya sokugaya asinciphisi ngenxa yokunyuka kobunzulu bokugaya, kwaye umngxuma wokubhoboza uqondile.
Ukuze ulungelelanise iimfuno zokwembiwa kwestrata ezahlukeneyo, kuphuculwe ukusebenza kakuhle kokomba, ukugrumba umbhobho kusetyenziselwa iinjongo ezininzi zokomba kunye nokuhanjiswa kwehydraulic epheleleyo kunye nolawulo lwendlela yophuhliso: oko kukuthi, isixhobo sokugrumba esinezixhobo ezahlukeneyo kunye nezixhobo. , unokusebenzisa impembelelo, i-rotary kunye ne-DTH isando kunye nezinye iindlela zokugaya;Ukuhlanjwa kwamaqula odaka, ukuvasa umoya ocinezelweyo kunye nokujikeleza okujikelezayo kunye nokubuyisela umva ukuhlamba kakuhle kungasetyenziswa.
