WORKING EQUIPMENT FOR ROTARY EXCAVATOR Russian patent published in 1995 - IPC

FIELD: excavator building. SUBSTANCE: working equipment of the rotary excavator includes bucket wheel with buckets, a beam with conveyor, placed along the beam inside the bucket wheel, i.e. in its cavity, immovable cylindrical ring with discharge window, cantilevers and chutes. The cantilevers are affixed to internal surface of the cylindrical ring, and the beam is installed between those using horizontal axle. The chutes are installed on both sides along the conveyor, which is located directly below the discharge window for the present beam setting. EFFECT: such a design allows one to reduce the time spent for soil, since the soil from the buckets enters directly the conveyor through discharge window, that enables executing handling unit members and significantly simplifies the structure of working equipment of the bucket wheel. 2 dwg
