<p>The invention relates to a bucket meant for rotor excavators that are used for extracting coal in open pits, but also in other fields. According to the invention, the bucket consists of a spout-like frame () with a cross-section in the shape of a regular semi-hexagon whose inclined sides are continued with two equal vertical segments playing the role of main eyelets for fixing the bucket on the rotor, and the material from the face is dislodged by means of a cutting blade consisting of several shape- and size-identical self-sharpening segments of the type which sharpen themselves as they wear out and with progressive cutting, assembled with several screws () on a support belt assembled by welding on the bearing frame ().</p> |
