ZGYX412-1分体式露天潜孔钻机
集尘效果改进:采用双联铁泵加单铁泵替代原铝泵，大幅提升集尘效果和泵的使用寿命；
马达回转头提升:双马达回转头改为单马达回转头，并且标配490排量马达，满足高转速工况需要；
整机布局调整完善:基础上对车身布局进行调整，使整机重心更加稳定，三筋履带改为单筋履带，加强行走能力；
过滤效果提升:针对实际工况，提高了过滤器过滤面积和过滤精度，且加大吸油管、回油管等通径，液压元件使用寿命可提升一倍；
油雾器容量加大:增大了油雾器容量，特别是柴油箱容量加大至130L，满足长时间工作需求；
提升机器耐用度:回转头主轴与钻杆卡套平键连接改为螺纹连接，避免长期高转速工作平键不耐用问题；
推进结构改进升级:推进提升链条销加粗，捕尘滑板座与定位套加强，结构更加可靠耐用；
机器操作更为便捷:捕尘行程从200mm增加至300mm，前斜钻杆架储存6根钻杆改为9根，操作更为便捷.
ZGYX412-1 Separated DTH Surface Drill Rig
Improvement of the dust collection effect: use the double coupling iron pump and the single iron pump to replace the original aluminum pump, and greatly improve the dust collection effect and the service life of the pump;
Motor rotary head lifting: double motor rotary head is changed to single motor rotary head, and standard with 490 displacement motor, to meet the needs of high speed working conditions;
Adjustment and improvement of the whole machine layout: on the basis of the body layout adjustment, to make the center of gravity of the whole machine more stable, the three-band track is changed to a single band track, to strengthen the walking ability;
Filtration effect improvement: according to the actual working conditions, the filter filtration area and filter accuracy are improved, and the general diameter of oil absorber and return pipe can have been increased, and the service life of hydraulic components can be doubled;
Increase the capacity of oil mist: increase the capacity of oil mist, especially the diesel tank capacity to 130L, to meet the long-term working needs;
Improve the durability of the machine: the connection of the rotary head spindle and the drill rod clamp is changed to threaded connection to avoid the durability of long-running high speed working flat key;
Promote structural improvement and upgrading: promote the promotion of the chain pin thickening, dust capture skateboard seat and positioning cover strengthening, the structure is more reliable and durable;
Machine is more convenient operation: dust capture travel increased from 200mm to 300mm, front inclined drill bar frame storage of 6 drill rods to 9, more convenient operation.
