1) Asalin tsarin atricone drills. Jikin rawar jiki: Akwai hakora guda uku da aka haɗa aka haɗa su tare, akwai zaren haɗaɗɗiya a ɓangaren sama. Gear: jikin ƙarfe mai siffar mazugi wanda ya ƙunshi jiki da hakora. Hakora sun kasu kashi biyu: niƙan hakora da saka hakora, bearings da nozzles ɗin ajiyar mai.

2) Ƙa'idar aiki na mazugi na abin nadi lokacin daabin nadi mazugi bityana aiki a kasan rijiyar, gaba dayan ɗigon ɗin yana jujjuya kusurwoyin dila, wanda ake kira juyin juya hali, kuma mazugi guda uku suna birgima a ƙasan rijiyar bisa ga gatarinsu, wanda ake kira juyawa. Matsin hakowa da ɗigon haƙora ya jure yana aiki akan dutsen ta cikin haƙora, yana sa dutsen ya karye (sakamakon murƙushewa). A yayin aikin birgima, mazugi yakan tuntuɓar ƙasan rijiyar tare da hakora guda ɗaya da hakora biyu, kuma matsayin tsakiyar mazugi yana jujjuyawa, yana haifar da rawar rawar jiki ta girgiza a tsaye. Wannan jijjiga mai tsayi yana haifar da igiyar rawar soja don ci gaba da damfara da mikewa. Ƙarƙashin igiyar rawar soja tana jujjuya wannan lokaci-lokaci yana canza nakasar kuzarin nakasa makamashi zuwa tasiri mai ƙarfi akan samuwar haƙora don karya dutsen. Wannan tasiri da tasirin murkushewa ita ce babbar hanyar da abin nadi ya karya dutsen.

Baya ga yin tasiri da murkushe dutsen da ke kasan rijiyar, abin nadi yana haifar da illa ga dutsen da ke kasan rijiyar. Yayin da mazugi ke birgima a kasan rijiyar, hakan kuma yakan sa hakora su zame da su a kasan rijiyar.
