1.Brief introductions of HZ-130YY hydraulic core drilling rig
HZ-130YY hydraulic core drilling rig adds shifting slipway on the basis of common drilling rig, which can realize rapid replacement of drilling tools and improve work efficiency and reduce labor usage.
2.Applications of HZ-130YY hydraulic core drilling rig
·this core drilling rig is suitable for drilling water well, soil exploration, geophysical exploration, road and building exploration and drilling blasting holes.
·drilling bits can be chosen according to the different soil condition, such as alloy, diamond and composite.
·2-9 grades of sandy clay and rock.
3.Features of HZ-130YY hydraulic core 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, safe and reliable.
·hoist is installed with holder, forming structure of double support wheel so that it 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 drilling rig adopts the conical clutch, which has the characteristics of large transmission torque, convenient operation and no maintenance.
