A first beveled wall 228 extends from the first side member 206 and a first mitered wall 238 extends from the first side member 206 proximate the first beveled wall 228, the first beveled wall 228 forming a first compound angle α1 with the base member 204 and the first mitered wall 238 forming a lower obtuse angle φL (best seen in
As previously described, the bucket defines a fill direction F and a center of gravity C and a Cartesian coordinate system including a X-axis, Y-axis, a Z-axis and an origin O positioned at the center of gravity C. The In one or more embodiments, the X-axis is aligned with the fill direction F of the bucket 202′ 202, and the first compound angle α1 includes a first component angle γ1 (best seen in
The In one or more embodiments, the bucket 202′ 202 may further comprise a second beveled wall 230 connecting the first beveled wall 228 to the rear member 210 and a second mitered wall 240 connecting the first mitered 238 wall to the rear member 210. As best seen in
As can be understood with reference to
Next, referring back to
As shown in
Likewise, the center of gravity is positioned a second predetermined distance 254 away from the mouth 214 along the X-axis and a ratio of the second predetermined distance 254 to the fill depth 250 ranges from 15 to 35% and may be approximately 20% in some embodiments. The X-Z plane defines a midplane 256 (sometimes also a plane of symmetry) and the trunnion attachment structure 236 defines a trunnion slot 258 with a longitudinal axis L258 that is parallel to the X-Z plane.
As mentioned earlier with reference to
Furthermore, as depicted in
Turning now to
The pad 268 defines the trunnion slot and the pin aperture extends orthogonally to the trunnion slot 258 for receipt of a pin 270 (vaguely shown in
The bucket, trunnion attachment structure, etc. may be made from any suitable material including iron, grey cast-iron, steel, etc. Also, the bucket, trunnion attachment structure, etc. may be integrally cast, forged or may be fabricated and assembled by fastening, welding, press fitting, etc. two or more pieces together to form the bucket, bucket assembly, or the trunnion attachment structure.
Any of the dimensions, ratios, angles or configuration of the bucket, trunnion attachment structure, etc. may be varied as needed or desired. Also, the dimensions and ratios involving the center of gravity may be based on the bucket as empty or with a payload depending on the application. Accordingly, values given and configurations shown are given by way of an example and not in any limiting sense.
In practice, a bucket, bucket assembly or trunnion attachment structure according to any embodiment described, shown or discussed herein may be sold, bought, manufactured, remanufactured, retrofitted, assembled or otherwise obtained in an aftermarket or OEM context.
For example, a trunnion attachment structure or bucket may be used as a replacement part. The bucket or bucket assembly may be used with a machine that has a rigging subassembly 300 such as that shown in
The configuration of the bucket shown in the figures is shorter along the fill direction, allowing a more efficient filling and dumping process to be used when employing the bucket. Also, the balance of the bucket during fill and dumping may be better than buckets previously known in the art. Furthermore, the capacity of the bucket may be increased compared to previous bucket designs, given the reduction of the load due to the elimination of the lower spreader bar.
