Abstract

FIELD: mining industry. SUBSTANCE: when handle 5 is pressed with effort exceeding required force of switching on, it is shifted, pressing spring 13, along glass 4 downwards moving starting valve 7. Thickening cone 9 disperses the void of glass 4 and compressed air goes to air-distributor 3 and through it to trunk 2. The hammer is brought into operation. When hammer goes into design conditions the required force of pressing on it increases. Further compression of vibration-proof insulator takes place. When the effort of preliminary tension of spring 12 perceptible by vibration-proof insulator is exceeded it begins to deform and spring 13 undergoes smaller deformations because its stiffness is more. That in under design conditions of hammer the stiffness of vibration-proof insulator becomes less, providing for effective reduction of vibration conveyed from impact assembly 1 to handle 5. EFFECT: enhanced efficiency of operation due to increase in vibration-proof insulation. 6 dwg
