  • the bell'crank is U-shaped to have a cleaning blade se [56] References cued cured to its second, lower end which sweeps through UNITED STATES PATENTS the bucket upon selective extension and retraction of 2,858,035 10/1958 Mett et a].
  • 214/510 the hydraulic cylinder. 3380,604 4/1968 Leese 214/767 3,426,928 2/1969 Campbell 214/146 E 13 Claims, 3 Drawing Figures BACKGROUND OF THE INVENTION Earthworking buckets, such as those employed on the boom of an excavator, oftentimes fail to fully discharge material contained therein when the bucket is pivoted to its dump position.
  • Tacky material such as clay
  • Tacky material is particularly difficult to dislodge from the bucket due to its adherence thereto.
  • the operator must normally bang the bucket against a stationary object or pry out the material manually.
  • Prior art attempts to provide selfcleaning means for the bucket are exemplified by the teachings of U.S. Pat. Nos. 1,653,905; 2,683,542; 2,858,035 and 3,438,526.
  • An object of this invention is to provide an economical and non-complex self-cleaning means for automatically sweeping through an earthworking bucket upon pivotal movement of the bucket between its rack-back and dump positions on a boom.
  • First linkage means are pivotally interconnected between an extensible actuating means and the boom and the bucket for selectively pivoting the bucket between such positions.
  • Second linkage means are interconnected between the boom and the bucket and have the self-cleaning means secured thereon for sweeping movements between the fore and aft ends of the bucket in response toextension or retraction of the actuating means.
  • FIG. 1 depicts a bucket arrangement II) and an excavator boom 11 pivotally connected to an upper, back side thereof by a pivot pin 12.
  • the bucket arrangement is hereindescribed in association with an excavator, it should be understood that the bucket arrangement can be readily adapted for use on other types of buckets, such as loader buckets.
  • An extensible and retractable actuating means 13, such as a double-acting hydraulic cylinder, has its rod 14 pivotally connected to a first linkage means 15 by a pin 16.
  • the first linkage means comprises a pair of first and second links 17 and 18, respectively, having their first ends pivotally connected to the rod by common pin 16.
  • the second end of link 17 is pivotally connected by a pin 19 to a flange 20, secured on the aft end of a bucket 21.
  • the second end of link 18 is pivotally connected by a pin 22 to a second linkage means 23.
  • the second linkage means comprises a third link 24 pivotally mounted on boom 11 by common pin 22 and a bellcrank 25 pivotally connected to a second end of link 24 by a pin 26.
  • the bellcrank has a self-cleaning means or elongated blade 29 formed on its lower end.
  • the blade extends between sidewalls 27 and is transversely disposed in bucket shell 30, having a generally U-shaped cross section, to automatically sweep therealong between the fore and aft ends thereof in response to actuation of cylinder 13.
  • FIG. 1 discloses cylinder 13 in its retracted condition whereby the bucket arrangement is maintained in its digging or dumping position of operation with boom 11, lever 24 and bellcrank 25 disposed in general vertical alignment.
  • the first and second linkage means Upon extension of the cylinder, the first and second linkage means will function to automatically retract blade 29 towards an aft end of the bucket wherein the bucket is maintained in its rack-back or load-carrying condition of operation.
  • Bellcrank 25 is thus disposed generally forwardly of the boom and link 24 with an open face of the bucket facing the boom. It should be noted that blade 29 sweeps the bottom of the bucket automatically during both the loading and dumping phases of bucket operation.
  • the selfcleaning bucket arrangement of this invention comprises an economical and non-complex design which can be adapted to conventional bucket arrangements expeditiously.
  • the integrated linkage system will not interfere with the line of sight of the operator of an excavator or like earthworking machine.
  • such linkage is positioned inboard of the buckets sidewalls to protect it against damage.
  • the bucket arrangement of this invention will provide the capability of scooping or dipping water and/or aqueous solutions from a trench, hole, etc.
  • the fluid will not drain from the bucket when the bucket is raised since the addition of the self-cleaning configuration does not disrupt the bucket enclosure.
  • firstlinkage means pivotally interconnected between said actuating means, said boom and said bucket for selectively pivoting said bucket between its rack-back and digging positions on said boom upon actuation of said actuating means
  • second linkage means interconnected between said boom and said bucket and having self-cleaning means secured thereon for automatically sweeping through said bucket between fore and aft ends thereof in response to actuation of said actuating means
  • said second linkage means comprising a link having its first end pivotally connected to said boom and a bellcrank pivotally mounted on said bucket and having its first end pivotally connected to a second end of said link, said self-cleaning means secured on a lower end of said bellcrank.
  • said bucket comprises a shell having a generally U-shaped cross section secured between laterally spaced sidewalls thereof and said self-cleaning means comprises a member pivotally mounted between said sidewalls.
  • first linkage means comprises a first link pivotally interconnected between said actuating means and said bucket and a second link pivotally interconnected between said actuating means and said boom.
  • a self-cleaning bucket arrangement having a lower end of a boom pivotally mounted on an upper, back side of a bucket
  • the invention comprising a link having its first end pivotally connected directly to said boom and a bellcrank pivotally mounted directly on said bucket, said bellcrank having its first end pivotally connected directly to a second end of said link and selfcleaning means secured on a lower end of said bellcrank and disposed within said bucket.
  • a self-cleaning bucket arrangement comprising a boom a bucket pivotally mounted on said boom,
  • first linkage means pivotally interconnected between said actuating means, said boom and said bucket for selectively pivoting said bucket between its rack-back and digging positions on said boom upon actuation of said actuating means
  • said first linkage means comprising a first link pivotally interconnected between said actuating means and said bucket and a second link pivotally interconnected between said actuating means and said boom, and second linkage means interconnected between said boom and said bucket and having self-cleaning means secured thereon for automatically sweeping through said bucket between fore and aft ends thereof in response to actuation of said actuating means, said second link and said second linkage means being pivotally'mounted on said boom at a common pivot means.
