Quarry drilling rig, rotary percussive drilling blastholes

Compact high-performance hydraulic drilling rig SM-90 is designed for drilling by the rotary method, geological, geophysical, surveying, technical, injection wells when carrying out engineering-geological surveys, drilling water intake and explosive wells up to 100 meters. The main method of drilling - rotary percussive using submersible hydropercussion machine. Installation optimally adapted to work on the slopes of granite, crushed stone and ore pits.

The rig SM-90 provides drilling in strong rocks with the hardness of f=6 ~ 20 Protodyakonov inclusive. The installation gear mounted units. The operator can perform drilling with the blowing of the bottom air compressor with the capacity of not less than 0.1 m3/s 6 m3/min), providing a pressure not less than the 4.9 105 PA. The hydraulic system allows: to flexibly control the flow of the drilling tool, to determine the weight of the drilling tool, installation and control of axial load, rasagiline drilling tool in the well, is also supported by the rapid extraction of the tool collapses and emergency situacio in the well. Moving the rotator hydraulic drive is used while drilling capacity drilling tool without interrupting him from slaughtering and performs jointly by the hydraulic cylinder feed work on the descent (ascent) of the instrument and its flow during drilling. Rotator - single-stage gearbox with spur transmission in a welded steel housing. Washing fluid or compressed air is fed through the gland inside rotator. Power and kinematics of the rotator also provides screwing (unscrewing) drill pipe or auger, due to which there is no need for a special mechanism for this purpose. The feed cylinder single - stage double-acting - provides a forced flow, the descent and ascent of the tool. To slow down the moving speed of the rotator at the end of the cylinder there are special damping devices. Managing the installation, including lifting (lowering) of the mast is carried out manually.

Design features:
1. Blocking mechanisms mounted installation modules, this allows you to use it in conditions of difficult terrain. Quick-detachable connections provide quick Assembly and disassembly of the core modules. A pair of removable wheels allows you to conveniently maneuver during transportation to the place of drilling.
2. The support stand has a special fastening system with ball joints that allow drilling at an angle, and provides additional stability on uneven surfaces.
3. The ballast provides additional stability when the occurrence of the shock pulses.
The rig SM-90 has three modifications of the actuator acting bodies: electro-pneumatic, pneumatic, and hydraulic.
