BUCKET CORNER, GRAVING GROUND EQUIPMENT AND MECHANICAL TOOL OF MUTUALLY FASTENING OF THE BUCKET CORNER AND GRAVING EARTH EQUIPMENT

摘要

The angle (10) of the excavation equipment bucket has a first section (12), a second section (14) and an intermediate section (16) between the first and second sections, all in different planes with respect to each other. A boss or protrusion (18) can be provided on the leading edge of the intermediate section. The intermediate section is at an angle with respect to both the first and second sections, which reduces the load stresses otherwise created in the traditional 90 ° bucket angle. The first section can have a wall (34) with a taper or bevel (36) towards the leading edge. The second section may have a wall (20) with a guiding flared wall section (22) that widens the bucket angle at the front (28). The intermediate section is preferably at an internal angle α, β of approximately 120 ° to 170 ° with respect to the respective walls of the first and second sections.
