FIELD: construction.SUBSTANCE: bucket of a dredger comprises a bottom with a cutting edge, side and rear walls. Side walls of the bucket are connected to the bottom at the angle of 45°. Thickness of side walls and the bottom reduces along the length of the bucket, starting from the end of the cutting edge. In the front part the cutting edges of the walls and bottom are sharpened.EFFECT: increased efficiency and quality of cleaning due to reduction of traction resistances and application of a bucket of trapezoidal cross section.4 dwg |
