FIELD: mining industry. ^ SUBSTANCE: said invention relates to percussion devices for disintegration, crushing and compacting of various materials. The key feature of the method is the increased tool velocity due to increase in number of armed assemblies and their movements, which exceed driving flow movement by several times, stepwise decrease in weight of the said assemblies and summing of their movements in order to increase the tool travel along the outer trajectory during acceleration, and utilisation of inertia force of the tool impact weight along the inner trajectory. The other feature is automatic change of the tool outer and inner trajectories ratio at the arming moment. The device consists of a bore, a tool, a tool motor with hydraulic grip, installed freely in each other, and a bore motor with mechanical high-speed pulley block. The design key feature is that two motors are used for arming, and the tool travels by force of the first arm of the robot in the bore, which simultaneously travels as regards to the device support. The other feature is that the tool automatic control is provided by the second arm of the robot, two alternative circuits (a logical controller and onboard computer, and an electromechanic relay circuit) being implemented, which provides for possibility of successive movement of the bore, tool and impact weight with guaranteed stops at outer and inner trajectories of the tool. The said features provide for significantly less energy consumption of percussion processes due to implementing advantages of gravitation and hydraulic energy together with elimination of their shortcomings (bulkiness and low percussion frequency for gravitation, low speed for hydraulic). The said invention provides for possibility of optimisation of parameters and modes of many percussion processes used for treatment of objects with various physical and mechanical properties. ^ EFFECT: optimised parameters and modes of percussion processes used for treatment of objects with various physical and mechanical properties. ^ 11 cl, 14 dwg |
