Definitions

  • the present invention relates to earthmoving machines, and more particularly, to a bucket for earthmoving machines.
  • Earthmoving machines include excavators, backhoes and quick hitches which uncouple buckets from earthmoving machines.
  • Earthmoving machines are used to excavate volumes of soil from a building site in the mining, construction, earthmoving and agricultural industries and comprise a vertically moveable bucket and a front edge configured to cut an earth surface. As the soil is cut from the earth surface by the front edge, it is deposited into the bucket for subsequent transport offsite.
  • the buckets have to be transported with the earthmoving machines to the work site. Transporting the buckets increases the builder's costs. It takes time for the operator of the earthmoving equipment to hitch or change the appropriate bucket for the operation, which represents a cost in time. In many instances, the appropriate bucket may be left elsewhere on the work site, which requires the operator to take the time to retrieve and couple the appropriate bucket and then go back to the required location on the work site.
  • the object of the present invention is to provide a bucket which is more versatile than currently available buckets for earthmoving machines which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice.
  • the present invention in one form, resides broadly in a bucket for an earthmoving machine, the bucket comprising:
  • a body comprising a pair of sides, a base and a rear surface defining an interior
  • a controller for the bucket is adapted to move the actuator so as adjust the bucket to the desired width. More preferably, the controller is located in the cockpit of the earthmoving machine which is attached to the bucket.
  • the plates are adapted to expand from a central component. It is also preferred that plates have wear pads to facilitate the sliding action.
  • the wear pad may be made of polytetrafluoroethylene. Alternatively, the wear pad may be made of a cobalt- chromium alloy.
  • the bucket is adapted to receive additional cutting teeth.
  • the bucket comprises two pairs of rams, a first pair of rams located at the top of the bucket and a second pair of rams located at the base of the bucket, wherein one of the rams of each pair is configured to actuate a left slide plate and the other actuator of each pair is configured to actuate a right slide plate.
  • the bucket also comprises a grab portion for placing and/or securing items in the interior of the body. More preferably, the grab portion is positioned on the rear surface of the body.
  • the first actuator is located at the top of the bucket and the second actuator is located at the base of the bucket.
  • Figure 1 is a perspective view of a first embodiment of the bucket of the present invention in a contracted state.
  • Figure 2 is a perspective view of the bucket of figure 1 in a first expanded state.
  • Figure 3 is a perspective view of the bucket of figure 1 in a second expanded state.
  • Figure 4 is a perspective view of the bucket of figure 1 in a fully expanded state.

  • a first embodiment of a bucket 10 for an earthmoving machine comprises a body 2 coated with 8mm metal plate, comprising a pair of sides 4, a base 6, a back surface 8 defining an interior 10.
  • a central component 12 holds an upper actuator in the form of a piston 14 and right ram 18 and a lower piston 16 and left ram 20 (see figure 13) which are used to simultaneously and uniformly expand or contract a right side plate 21 and a left side plate 22 respectably from the central component 12 of the bucket 10.
  • the right side plate 21 is attached to a right bucket plate 24 and the left side plate 22 is attached to a left bucket plate 26.
  • the right bucket plate 24 is adapted to slide underneath the left bucket plate 26.
  • Wear pads (not shown) are used between the right bucket plate 24 and the left bucket plate 26.
  • the wear pads are made of polytetrafluoroethylene to facilitate the sliding action.
  • the bucket 10 has five permanent cutting teeth located along a front edge of the body 2.
  • the permanent cutting teeth comprise a first tooth 30, a second tooth 32, a third tooth 34, a fourth tooth 36 and a fifth tooth 38.
  • the mid section cutting teeth 32, 34 and 36 span 285 mm in width and the outer cutting teeth 30 and 39 result in a bucket with a 300 mm length along the front edge of the body 2 in the contracted state (as shown in Figures 1, 5 and 9).
  • the width of the front edge can expand to 600 mm in length.
  • Each tooth is 40 mm in width with a 60 mm gap between the second tooth 32 and the third tooth 34 and between the third tooth 34 and the fourth tooth 36.
  • the bucket 10 width is expanded or contracted by a controller (not shown) located in the cockpit of the earthmoving machine to which the bucket 10 is attached.
  • the bucket 10 has a hitch 44 which is an attachment point for an earthmoving machine (not shown).
  • Each side plate 20 and 22 of the bucket 10 has front guard 46 and a rear guard 48.
  • each of the cutting teeth comprises a front cutting edge 50, a top cutting edge 52 and a base cutting edge 54 to cut into a soil surface.
  • Hard coating in the form of spray on bisalloy or boron provides a surface resistant to deformation or damage during use.
  • the teeth each extend 120 mm in length.
  • the bucket 10 has 2 pairs of actuators; a first pair 56A and 56B located at the top of the bucket 10 and a second pair of actuators 58A and 58B located in the base of the bucket 10. Actuators 56A and 58A actuate a left hand bucket plate 26 and actuators 56B and 58B actuate a right hand bucket plate 24. The second pair of actuators 58A and 58B located in the base of the bucket 10 are covered by the bucket plates 24 and 26. The actuators 56A, 56B, 58A and 58B are fixed into position in the body 2 by adhesive compound (such as mastic).
  • adhesive compound such as mastic
  • the bucket 10 also includes a grab portion (not shown) located on the back surface 8 of the body 2 for placing and/or securing items in the interior of the body.
