1.Brief Introduction of YQZ-50B hydraulic drilling rig The YQZ-50B hydraulic portable drilling rig with diesel engine is suitable for geological drilling in complex terrain such as mountains, hills, river courses, engineering geological investigation of buildings, drilling of blasting holes and so on. To meet the needs of different users, the rig can be equipped with one of three kinds of power : diesel engine, gasoline engine and electric motor. And the default is diesel power. 2.Features of YQZ-50B hydraulic drilling rig The portable drilling rig is compact in structure, small in size and light in weight. YQZ-50B drilling rig can also be quickly disassemble, is more convenient to transport especially suitable for mountainous and hilly complex terrain work. Compared with similar products, the portable rig is equipped with dual cylinder hydraulic feed system with high drilling speed and high efficiency. The operation panel of this type of portable drilling machine is equipped with the pressure gauge of the bottom of the hole to indicate the pressure in the hole, and the operator can make the adjustment according to the different terrain conditions. The portable rig is equipped with a high-performance 4 gear shift system. It is convenient for operators to freely adjust the positive rotation speed according to the geological conditions. In addition, it also has an ultra slow reverse gear, which is convenient for operators to remove drill pipe drill tools. This type of portable drilling rig is equipped with automatic hoisting and lifting system, combined with tower, which greatly saves labor intensity and improves work efficiency. The drill is equipped with a ball clip clamping mechanism and a six party active Drilling Pipe, which can realize the non stopping of the pole, and the efficiency is high, and the safety is reliable. 3.Specifications of YQZ-50B Specifications Dynamic part diesel engine Drill weight 145kg Drill rig size 1250*650*1050mm Drill pipe diameter 32mm Borehole diameter 46mm 60mm 75mm Borehole depth 50-60m 40-50m 30-40m Gear box 4 gear transmission Gripping type ball ball card holding type Vertical axis type six prism Vertical axis to side length 36mm Vertical axis length 1600mm Vertical rotation speed of vertical shaft 220/580/960rpm Reverse rotation speed of vertical axis 130rpm Maximum output torque of vertical shaft 210n.m Vertical shaft double oil cylinder stroke 400mm Maximum inlet force of double oil cylinder 7kn Maximum lifting force of double oil cylinder 15kn Vertical shift speed 0.035m/s Vertical axle load down speed 0.085m/s Oil pump flow rate 10ml/r Pressure gauge pressure range 0-6mpa Rated pressure of oil pump 20mpa
