FIELD: engineering of striking machines for destruction, crushing or densification of various materials.
SUBSTANCE: method is special mainly because of division of main driving flow of oil pump of base machine on potential energy flows, which are fed simultaneously during resetting of implement for extraction of implement from the clamp and its movement, and which during beginning acceleration moment fully detach from main flow to provide for forced detachment of clamp from implement and forced movement of clamp after the implement. Values of potential energy flows strictly comply with requirements, determined by geometrical dimensions of drive and its units, parameters of operation mode of base machine pump, calculated energy of single strike. Device consists of shaft with upper and lower lids, hydraulic drive, including piston hydraulic motor with step-up gearings, clamp with step-up gearings and electro-hydraulic switches with non-contact control system, implement with hollow tail and energy accumulator, made in form of springs, carriage with supporting guide. Construction is mainly special because hydraulic motor is of one-sided effect and is mounted jointly relatively to shaft, shape of which is cylindrical and it is made moveable relatively to guide with supporting thorns, connected to handle by means of carriage, while anvil block of implement is rigidly connected to external ring having piston rings on ends, while springs of energy accumulator are mounted in the hollow between it and the tail of implement.
EFFECT: possible operative control over drive energy flow and increased energy of the implement during impact.
