FIELD: earth-moving facilities. ^ SUBSTANCE: invention relates to machines designed for digging wet cohesive soils, especially in winter and it can be used at construction and land reclamation works. Proposed excavator bucket contains bottom, front, rear and side walls, vibration exciter, heat transfer system and additional inner wall made of flexible elastically deformable material to form sealed space filled with heat carrier between said wall and front, rear and side walls of bucket. Vibration exciter made in form of elastic shells is arranged along cross perimeter of bucket, some ends of shells being stopped and arranged in sealed space at rear wall of bucket, and other ends are connected with manifold installed in space of bucket rear wall, manifold being connected with source of liquid pressure pulses. ^ EFFECT: improved efficiency of operation art digging wet cohesive soils owing to reduction of soil sticking to bucket. ^ 5 cl, 4 dwg |
