Following is a drilling machine manufacturers to give you a brief introduction of the development history of drilling equipment, in the hope that you can help.
As early as the 2nd century BC, China has a useful human with the help of bamboo bow elastic conical drill hit bottom and into the original impact drill, then long-term use in rural China. In the 1950 of the 20th century we imported steel wire rope impact drill, began development in the early 60 big and small cones, flushes the cone and other simple water well drilling rig. Started to develop before and after 1966 are circulating Rotary drilling rig, around 1974, developed reverse circulation composite drilling Rotary drilling rig, and late 70 created a down-the-hole vibration Rotary drilling rig. European countries in the 19th century mainly use rope impact drill, in the 1860 of the 19th century, France first used Rotary Rotary drilling rig, passed after United States and rapid development. In the 1950 of the 20th century, began development of reverse circulation Rotary drilling rig, later appeared again with compressed air as washing medium instead of mud Rotary Rotary drilling rig, between the 70 and the development of the driving head of hydraulic rotary drill rig.
