1. The brief introductions of HZ-130YY hydraulic drilling rig On the basis of common drilling machine, The HZ-130YY hydraulic well drilling rig adds the shifting slide rail of the drill rig ,which can realize rapid replacement of drilling tools and improve work efficiency and reduce labor usage. 2. The applications of HZ-130YY rotary drilling rig This drilling rig is suitable for drilling of wells drilling, Made in China water well,field irrigation well, engineering water well,precipitation well and so on; survey exploration, geophysical exploration, road and building exploration, and drilling blasting holes. Drill bits such as alloy, diamond and composite plates can be selected for drilling according to differentassise. It can drill 2-9 grades of sandy clay and rock. 3. The features of HZ-130YY rotary drilling rig The automatic feed mechanism with oil pressure can improve the drilling efficiency and reduce the labor intensity of the workers The ball card holding mechanism is used instead of the chuck, which can be operated without stopping the rod, and the operation is convenient and safe and reliable. The hoisting machine is equipped with a holding frame to form a double-sided supporting star wheel structure, can withstand strong impact. Four groups of bearings are located in the vertical shaft box to ensure that the gyration is rigid enough to cope with the complicated geological conditions such as the gravel layer, the pebble layer and so on. This machine adopts the conical clutch of national patent technology, which has the prominent characteristics of large transmission torque, convenient operation and no maintenance. 4.The specifications of HZ-130YY rotary drilling rig HZ-130YY rotary drilling rig Drilling depth 130m Maximum opening hole diameter 75-220mm End hole diameter 75mm Driven-pipe diameter 53/59*4200mm Drilling pipe diameter 50mm Borehole angel 90°-7° Power(diesel engine) 13.2kw Drilling rotating speed 2200r/min Weight dimension 850kg/2400*950*1400 Vertical shaft Vertical rotating speed 142 285 570r/min Vertical stroke 450mm Windlass Single rope lifting capability 9.6kn
