FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to earth-moving machines, to ladles of dragline excavators, in particular. The ladle of dragline excavator contains housing 1 with bottom 2, V-shaped deflector 6 with front tooth 7 and cutting edge 8 with teeth 9. The bottom 2 is made composite from movable 3 and fixed parts. The movable part 3 of the bottom 2 is coupled with housing 1 so that angular position with regard to horizontal line can be changed. Two springs 4 are installed at the sides of internal housing part. The springs are covered with rubber casing 5. The low end of each spring 4 is linked with movable part 3 of bottom 2, while the upper end is coupled with housing 1. ^ EFFECT: increased efficiency of drag-line excavator and reduced time for ladle filling with ground. ^ 2 dwg |
