我厂利用插入式混凝土振动器电机及软管、软轴,制成高速砖墙钻孔机。该机经过一年的使用测定表明:可钻φ20～30,深400毫米以内的砖墙孔。一个φ28深240毫米的实心砖墙孔,只要17秒钟即可钻通;钻孔工效与人 Our factory uses plug-in concrete vibrator motors and hoses and flexible shafts to make high-speed brick wall drilling machines. After one year’s use of the aircraft measured that: drilling φ20 ~ 30, 400 mm deep brick hole. A solid brick wall hole with a diameter of φ28 and a depth of 240 mm can be drilled in as long as 17 seconds; drilling ergonomics and people
