Title: Digging change hydraulic DTH drilling Model: WJ-QK80 performance parameters: 1 For rock hardness:. F = 6-20 2. punctured range: 76-90mm 3. Promoting a stroke: 3.5m 4. punctured lowest level height: 250mm Applications: 1 sized open pit mines, water, roads, ports and other projects 2. General hard ore, mine rock, etc. Description: 1. truly become rigs drilling machine, and implemented on the same track four machine interaction change, peeling drill ,, Y28 rock drill, Y45 rock drill 2. Our transformation does not affect the digging machine digging machine function, do not go to the second arm, easy to replace. 3. Increase the arm cylinder design, so that the digging machine stops at different slope When the surface, can keep drilling vertical, the real effective blasting. The use of imported automation, so that the speed of the case of drilling in hard rock is slow, then fast in case of soft, soft landing of hydraulic drilling, drilling realization Intelligent, reduce the failure rate of mechanical transmission digging machine 5. We need to change the oil system, using the principle of the dispensing valve, allowing quick and easy change digging machine transformation, fast access push to achieve the transformation scene, no advantage to manufacturers of products 1. flexible 2. 3. Punch wide angle variation using a wide range, can play all kinds of rock drilling speed 4. Tel: 13544187954
