ApplicationThe HXY-500 medium and deep rock core drilling machine is a complete hydraulic pressure feed-in,Website:http://www.rejeedrilling.com, mechanical impetus head rotary type drilling machine independently created by our institute. It is mainly used in all kinds of engineering drilling such as diamond or hard alley rock core drilling in solid mineral bed, project address exploration, underground water and well etc. It is also suitable for engineering drilling such as ventilation in mine sap, drainage and stake radix perfusion stake hole, and shallow petroleum, natural gas, coal ,dyke slurry injection and leakage filling.Features1, The drilling machine has many gears, i.e., 2×(5+1),10 levels forward rotation, 2 levels reverserotation, many rotating levels, wide scope, suitable for small caliber diamond rock core drill in and big caliber hard alley engineering core drill in. The active drill stem isΦ89×79,interior boreΦ52 water leading bore has big diameter.2, The entire structure is simple, with reasonable layout. The intension of the components is high and the stability is great; it is easy to dismantle and move, and convenient to repair, maintain, firm and endurable.3,The clutch adopts Dongfeng EQ140 gear box, the components are compatible with high standard degree, easy to operate and maintain. The drilling machine adopts hydraulic pressure assistor operating clutch, which reduces the working intension of the operating personnel.4,The drilling machine is matched with corresponding apparatus, which is favorable to master the condition. It has few operating handlers, and the layout is reasonable, so the operation is flexible and convenient.Technical specificationsDataItemSpecification of drill stemDepth of drill bore     DrillingInparametersΦ421500mΦ501100mΦ60950mAngel of drill bore 0~360°Rotating speed of vertical axis( r/min)Forward rotating high speed (II gear)979,635,399,227,134Forward rotating low speed (I gear)289,188,118,67,40Reverse rotating high speed (II gear)127Reverse rotating low speed (I gear)38Feeding-in journey of vertical axis600 mmDiameter of vertical axis interior hole91 mmMaximum feeding-in pressure adding capacity of vertical axis93.3 KNMaximum lifting capacity of the vertical axis138.5 KNWindlassElevating capacity (single rope)40KNDiameter of steel ropeΦ18.5mmSpecification of steel rope6T(25)-18.5-170-1Elevating speed m/s3.4;2.07;1.31;0.74;0.48Hydraulic pressure systemTwin pump displacement L/min11+32Working pressure0-8MPaMinimum displacement L/min11Maximum displacement L/min43Piston journey of the portable machine device500 mmEngineElectric engineY225s-4    1480r/min  37KWDiesel engine4102DBZ    48KWSizeLength×width×height(mm)3100×1370×2050Weight3200kg
