FIELD: earth-moving equipment. ^ SUBSTANCE: proposed working member of multibucket excavator contains main rotor stationary secured on drive shaft. Working member is furnished also with additional rotor installed on drive shaft for axial displacement relative to main rotor by means of expansion mechanism. Additional rotor is turned relative to main rotor though half of pitch of main rotor buckets. Both rotors have equal number of buckets, pitch of buckets, width of buckets and diameter of rotors. ^ EFFECT: enlarged operating capabilities of rotary multibucket excavator. ^ 3 dwg |
