BUCKET CORNER, GROUND ENGAGING TOOL AND MUTUAL MECHANICAL ATTACHMENT THEREOF

摘要

An earthmoving equipment bucket corner 10 has a first portion 12, a second portion 14 and an intermediate portion 16 between the first and second portions, all in different planes to one another. A boss or lug 18 can be provided on the leading edge of the intermediate portion. The intermediate portion is angled relative to both the first and second portions, which alleviates the load stresses otherwise created in a traditional 90° corner. The first portion can have a wall 34 with a taper or bevel 36 towards a forward edge. The second portion can have a wall 20 with a leading flared wall portion 22 that widens the corner at the front 28. The intermediate portion is preferably at an included angle a, beta of around 120° to 170° with respect to the respective walls of the first and second portions. The angle phi is at or approximately 20° compared with the angle psi at or approximately 30° to the floor portion 34. This reduces the height hi of the corner to height h2, which increases the included angle beta by approximately 10°. Similarly the included angle a between the plane of the second portion and the plane of the intermediate portion decreases by about 10°.
