Abstract
A bucket for a work machine is disclosed. The bucket has a base plate at a top end of the bucket, a lip plate at a bottom end, and a pair of side plates that extend down from the base plate to the bottom end. A wrapper has a first curved portion, having a first radius of curvature, that extends to a first flat portion. The first flat portion extends to a second curved portion having a second radius of curvature. The first flat portion extends between the first curved portion and the second curved portion.
Claims16
A bucket for a work machine, comprising:
- a lip plate at a bottom end of the bucket;
- a base plate at a top end of the bucket;
- a first side plate and a second side plate extending downwardly from the base plate to the bottom end of the bucket;
- a wrapper attached to the lip plate and the base plate, the wrapper comprising:
- a first curved portion having a first radius of curvature at the bottom end of the bucket extending between a first flat portion and a second flat portion,
- a second curved portion having a second radius of curvature extending from the first flat portion towards the base plate, and
- the first flat portion connecting the first curved portion and the second curved portion is substantially planar;
- the second flat portion connecting the first curved portion and the lip plate;
- a first curved corner and a second curved corner, the first curved corner extends from a first side of the wrapper to the first side plate, and the second curved corner extends from a second side of the wrapper to the second side plate;
- and
- one or more wear brackets extend from a first wear plate on the first side plate and a second wear plate on the second side plate, the one or more wear brackets configured to curve around the first curved corner and the second curved corner, respectively.
A work machine, comprising:
- a base configured to be supported on a ground surface;
- a revolving frame coupled to the base and rotatable about an axis;
- an arm coupled to the revolving frame;
- and
- a bucket having a base plate at a top end of the bucket and a hinge assembly including a pair of hinge plates connected to the base plate at the top end of the bucket, the bucket pivotally coupled to the arm and supported via the hinge assembly, the bucket further comprising:
- a first side plate and a second side plate extending downwards from the base plate to a bottom end of the bucket,
- a lip plate at the bottom end,
- a wrapper attached to the lip plate and the base plate,
- the wrapper having a first flat portion, a second flat portion, and a first curved portion having a first radius of curvature at the bottom end of the bucket, the first curved portion connecting the first flat portion and the second flat portion, wherein the first curved portion has a first arcuate length along the wrapper, the first curved portion orienting the first flat portion and the second flat portion of the wrapper to extend at an obtuse, first angle relative to one another,
- the wrapper including a second curved portion having a second radius of curvature, the second curved portion connecting the first flat portion and the base plate,
- the first flat portion connecting the first curved portion and the second curved portion is substantially planar;
- wherein the second curved portion has a second arcuate length along the wrapper that is larger than the first arcuate length of the first curved portion, the second curved portion orienting the first flat portion and the base plate to extend at a second angle relative to one another that is less than the first angle,
- wherein the first flat portion includes a first length extending between the first curved portion and the second curved portion, wherein the second flat portion includes a second length extending between the lip plate and the first curved portion, the second length being less than the first length,
- a first curved corner and a second curved corner, the first curved corner extends from a first side of the wrapper to the first side plate, and the second curved corner extends from a second side of the wrapper to the second side plate;
- and
- one or more wear brackets extend from a first wear plate on the first side plate and a second wear plate on the second side plate, the one or more wear brackets configured to curve around the first curved corner and the second curved corner, respectively.
