(54) EXCAVATING MACHINE WITH BUCKET OF ACTIVE ACTION
(57)
FIELD: mining and civil engineering, particularly, devices for excavation and moving the ground. SUBSTANCE: machine may be used in excavation of rocks, frozen grounds without their preliminary loosening in construction and mining industry. The excavating machine with bucket of active action includes jib, dipper stick with safety dog, source of energy carrier and pipeline system located on platform, jib and dipper stick and interconnected with one another by lengths of flexible hoses to form single energy-conducting circuit from source of energy carrier to percussive mechanisms of bucket. Dipper stick pipeline is telescopic. EFFECT: higher reliability and efficiency of excavating machine operation due to elimination of flexible hose loop in pipeline system for supply of energy carrier to bucket of active action. 3 cl, 4 dwg
