The cone type drilling machine SBSh-160 / 120-40 is hydroficated, with an electric drive, designed for drilling technological blast holes in rocks with a strength of f = 4-8 units. on a scale prof. Protodyakonova at open pit mining of minerals, as well as when performing work on the ejection of ledges of quarry sides along the ultimate contour.
The components of the machine are placed on a platform that is mounted on a tractor-type tracked track.
All mechanisms of the hydraulic system of the machine operate from the main pump, which is driven by an electric motor with a power of 75 kW, powered from career networks with a voltage of 380 volts.
The mast is a welded spatial truss made of square tubes with an open front panel. Inside the mast are located: a rotary feed mechanism, a carousel-type separator with four drill rods, a lunette and a screw-unscrewing mechanism of the drill stand.
- power bearing metal structures of the machine are made of alloy steel;
- hydraulics components - mobile version, Bosch Rexroth;
- machine drives have a margin of safety at maximum loads, which significantly increases the life of the main units;
- motor protection from cavitation is applied, including when the machine moves downhill;
- performance control of the main pumps is carried out by feedback from consumers depending on the operations performed. Due to the optimal use of the power characteristics of adjustable pumps, the power of the drive motor is reduced;
- welded joints of pipelines and high-pressure hoses of foreign manufacture are used, eliminating oil leakage from the hydraulic system;
- To control the drilling process, modern measuring instruments are used;
- all auxiliary operations are automated;
- disabling the stroke motors when towing the machine;
- with the mast raised and lowered, the machine is optimally aligned.
