Applicationthis portable drilling machine is a kind of small,Website:http://www.rejeedrilling.com, well-designed and portable sampling and drilling equipment. This backpack type core drill can replace traditional trenching, exploratory shaft sinking and physicochemical exploration abnormal verification.Meanwhile, it can greatly reduce the destroy of vegetation and preserve the ecological environment. It is a necessary technological means to carry out areal geological mapping, physicochemical exploration sampling, paleomagnetic sampling and geological disaster prevention in shallow geological survey.Feature1, Convenient to carry--a set of 3m drill in standard configuration and its accessories can be put into a backpack, whose total weight would not exceed18kg; 2, Complete accessories--all tools, spare fuel, potable water and personal belongings can be put in one backpack; 3, Flexible operation--easy to carry out assembly and disassembly, and rapid coring; 4, Rapid drilling hole--the working efficiency is unparalleled to save both time and labor, and the service life is long;5, Well-adapted--the drill can complete coring in various complex terrain to provide reference for later detailed exploration;6, Economize on manpower-- the efficiency produced by oil consumption per liter using the drill is 10 times of that using hand excavation.Technical DataQuartzite69 mm/minuteKillas119 mm/minuteBasalt127 mm/minuteSandstone130mm/minuteDolomite226 mm/minuteLimestone241 mm/minuteOther important technical parametersWater consumption15 L/hrOil consumption0.58 L/hrCoring diameter20.5 mm/36mmDrilling diameter26.4 mm/42.5mmRotate speed of drill1920rpmDrill power1.81 horsepower full-speed operation
