Definitions

  • This invention relates to apparatus that enables connection of an implement to an arm assembly of machinery. More particularly the invention relates to apparatus that enables an arm assembly of an excavating machine to connect to an implement or tool, such as a bucket, ripper or rock grab.
  • Excavating or earthmoving machinery require different types of implements to be connected to a working arm assembly of the machine in order to undertake a particular task such as digging into earth and rock, moving earth and rock or for demolition purposes.
  • implements used to undertake these tasks vary greatly as do the connections to arm assemblies of the machines, one such connection is known as a quick hitch.
  • a quick hitch is located between the end of the arm assembly of the machine and the implement and engages a set of pins located at the top of the implement in order to quickly pick up and attach the implement.
  • a known arrangement is disclosed in Australian Patent Application No. 2004201141 to Darryl Bates which recites a pair of ears that project from the top of a tool, such as a bucket, with the ears having opposed apertures, one set of apertures being circular and the other set of apertures being in the form of elongate slots. These apertures support first and second location pins that extend between the ears to account for different distances between the locating pins.
  • a pair of elongate links fit to the respective ends of the pins in order to locate the second pin within the elongate slots, the links being attachable to the ears.
  • a particular problem with this arrangement is that many such links of differing dimensions must be stocked by a supplier to fit onto the two pins to vary the distance between the pins, in order to fit excavating equipment of different manufacturers.
  • Another potential problem is damage that can occur to the pins of the bucket when a hitch contacts each of the pins in order to engage the implement attached to the set of pins.
  • the pins due to the excessive force applied by the hitch, at the time of engagement with the pins, chips, deforms and bruises each pin, generally along the entire length of the pin which has a constant diameter.
  • the continual damage to the pins makes them extremely difficult if not impossible to remove and replace the pins as the pins cannot be moved through the apertures on each pin support plate due to the excessive damage to the pins.
  • US patent application No. 2003/131682 discloses a connector assembly that mounts an implement to a prime mover such that the distance between two pins is varied through the rotation of the two pins with respect to one another due to the eccentric location of bores in flanges associated with the pins.
  • the prime movers typically include excavators and back hoes and facilitates the direct attachment of the implement to the prime mover.
  • US patent No. 4133121 provides an adaptor for direct connection between an implement and a back hoe machine.
  • Various sized pins and bushes fit between a pair of ears in order to attach one of a number of buckets to any one of a plurality of different back hoe machines.
  • US patent application No. 200810092414 there is disclosed a spacing assembly kit provided on one or both of the pins of a bucket. Its purpose is to produce the coupling width along the pin where the arm or boom of the machinery grabs the bucket.
  • the assembly kit includes a spacing element and spring clamp with the spring clamp inhibiting the movement of the spacing element along the pin. Therefore the spacing clamp locks the spacing element onto the pin through pin contact surfaces 44 so that it does not move.
  • the device disclosed in this document attempts to solve the problem of free floating spaces that arc provided on the shaft or pin which can be damaged or get in the way of any arm assembly that is attempting to connect to the pins.
  • the present invention provides an alternative arrangement to the prior art to enable connection of a range of implements to a range of machinery.
  • apparatus for connecting an implement to an arm assembly of machinery, the implement having a first pin support plate spaced apart from a second pin support plate, each pin support plate having a pair of apertures, the apertures being located to provide first opposed apertures and second opposed apertures facing across a space between the first and second pin support plates, the apparatus including:
  • the apparatus further includes a second pin and bush assembly having the second pin and a pair of bushes adapted to cooperate with the second pin, the second pin extendable through the pair of bushes of the second pin and bush assembly and through the second opposed apertures of the first and second pin support plates.
  • one of the bushes in said pair of bushes of said second pin and bush assembly engages with the first pin support plate and the other bush in said pair of bushes of said second pin and bush assembly engages with the second pin support plate.
  • the second pin and bush assembly has two pairs of bushes adapted to cooperate with the second pin, wherein one pair of bushes engages the first pin support plate and the second pair of bushes engages the second pin support plate such that a pair or inner bushes is defined on the second pin and with respect to each of the first and second pin support plates, such that the length of the second pin between the inner bushes of the second pin and bush assembly is variable to accommodate the dimensions of a pin engagement portion of the arm assembly of machinery.
  • Each bush may have identical eccentric apertures.
  • the pin may have at one end a mounting flange to enable the pin to be affixed to either the first pin support plate or to the second pin support plate.
  • the second pin may have at one end a mounting flanges to enable the second pin to be affixed to either the first pin support plate or to the second pin support plate.
  • the mounting flange of the pin may be mountable to the respective pin support plate through one of the bushes of said first pin and bush assembly.
  • the mounting flange of the second pin can be mountable to the respective pin support plate through one of the bushes of said second pin and bush assembly.
  • a mounting disc can be provided on each of the first and second pin support plate either side of each aperture of the first opposed apertures and the second opposed apertures in the first and second pin support plates and wherein further a respective bush is mountable to a corresponding mounting disc.
  • one or more of the bushes has a flange, a portion of the flange positioned in use within a respective aperture of the first and second pin support plates.
  • the first pin and bush assembly may be rotatable to adjust the spatial separation of the pin and the second pin and is mountable to each of the pin support, plates in any one of a number of predetermined rotational positions.
  • the second pin and bush assembly may be rotatable to adjust the spatial separation of the pin and second pin and is mountable to each of the pin support plates in any one of a number of predetermined rotational positions.
  • Either or both of the pin and the second pin may have a mid-section formed between a first end section and a second end section, the first and second end sections having the same diameter and larger than the diameter of the mid-section, such that only the mid-section is exposed to the pin engagement portion of the arm assembly.
  • Ether or both of the pin and the second pin may be heat treated to increase the hardness of either or both the pin and second pin and thereby increase resistance to damage from engagement with the pin engagement portion of the arm assembly.
  • an implement connectable to one of a plurality of machine arm assemblies using the apparatus of any one of the preceding claims coupled to the spaced apart first and second pin support plates of the implement.
  • a third aspect of the invention there is provided a method of connecting an implement to an arm assembly of machinery, the implement having a first pin support plate spaced apart from a second pin support plate each pin support plate having a pair of apertures defining first opposed apertures and second opposed apertures facing across a space between the first and second pin support plates, the method including the steps of:
  • FIG. 1 and 2 there is shown apparatus for connecting an implement, such as a bucket 5 (in Figure 5 ), to machinery, and more particular to a quick hitch device which is located at a distal end of an operating arm assembly of an excavating machine.
  • the apparatus includes a first pin and bush assembly 2 and a second pin and hush assembly 3.

  • Bushes 32 and 38, as well as bushes 44 and 50, are primarily used to vary the spatial separation between pins 28 and 40.
  • Bushes 34 and 36 of the first assembly 2 and bushes 46 and 48 of the second assembly 3 are primarily used as spacers to vary the distance along each of pins 28 and 40 that can engage with a quick hitch attached to the end of an arm assembly of the excavating machine. More inner bushes may be used, as required to vary the length of pins 28 or 40 exposed to the quick hitch. Each of the bushes has an eccentric aperture therethrough, the purpose of which will be discussed hereinafter.
  • Each of the assemblies 2 and 3 is adapted to fit between upright parallel pin support plates 4 and 6, which are located at a top face 8 of the implement or bucket 5 as is shown in Figure 5 .
  • Each of the pin support plates 4 and 6 may be integrally formed with the bucket 5 or otherwise attached to the top face 8 of the bucket 5.
  • Located at one end of the respective pin support plates 4 and 6 are apertures 9 and 10 directly opposed to one another across a space 7 between the pin support plates 4 and 6.
  • a further set of apertures 11, 13 is located at the opposite end of each of the pin support plates 4 and 6.
  • Mounting discs 12 and 14 are located either side of support plate 4 such that each of the discs 12 and 14 have apertures that correspond with aperture 9.
  • mounting discs 16 and 1 are located either side of plate 6 around aperture 10.

  • Mid-section 15 is exposed to engagement with a hitch of an arm assembly.
  • Each of the end sections 17 and 19 are respectively covered by the bushes, mounting discs and pin support plates.
  • end section 17 resides within aperture 9 and is substantially covered by each of bushes 32 and 34 as well as mounting discs 12 and 14 formed either side of the pin support plate 4.
  • the second end section 19 of pin 28 is respectively covered by bushes 36 and 38, mounting discs 16 and 18 and a portion of the pin support plate 6.
  • Each of the end sections 17 and 19 are not exposed to the engagement of a hitch and therefore are less likely to have damage occurring through that engagement. Only section 15 could, over time, potentially be chipped, deformed or bruised.
  • the whole pin 28 may be heat treated, or otherwise treated so that it is hardened and strengthened, generally to a Rockwell hardness of 45 to 50 on the C scale.
  • the various diameters of sections 15, 17 and 19 will change according to the particular application of the pin and the implement to which is attached.
