FIELD: mechanics, construction equipment.
SUBSTANCE: said invention relates to manufacturing of bucket dredges, in particular, to manufacturing of dredging buckets for light dredges. Technical effect - less material and labour costs, work study of bucket manufacturing process to provide for required bucket pressure on the ground for complete filling thereof during dredging, as well as prevention of earth drop-out during the bucking line motion. The method to manufacture dredging bucket implies welding the casing to base and bottom. A trapezoid is cut out of a metal sheet, then it is folded along the centerline, bottom ends are put together with the base, and the shorter of parallel sides of trapezoid is put together with the bottom. Tilting angle of the trapezoid side is maintained in the range of 60 to 65°; trapeziod metal sheet is folded along the centerline with a radius R=(0.35-0.40)B, where B - specified casing width at base.
EFFECT: enhanced performance characteristics of drag bucket with lesser material costs.
