Definitions

  • a backhoe bucketv of the type includingtwo sections attachedfor relative pivotal movement and an actuator for pivoting the sections relative to each other, and an attachment adapted forengagement by the sectlons.
  • a backhoe One common type of apparatus for earth excavation and incidental handling of related materials, commonly known as a backhoe, includes a bucket pivotally attached to a dipper stick which is in turn movably attached to the rear of a vehicle.
  • the bucket is oriented so that its operative leading edge contacts the earth in motion generally toward the vehicle.
  • most backhoe buckets have been designed in such a way that they are not suitable, without extensive changes, for more than one type of use.
  • a few multiple function buckets have been designed, but none have been generally satisfactory.
  • Other objects of this aspect include providing such a bucket which eliminates undesirable tooth marks on many jobs, can be used to pry out rocks, pavement and the like, and which is also useable as a shovel or clamshell.
  • a principal object of a second aspect of the invention is to permit other attachments to be used with the backhoe without disconnecting the bucket therefrom.
  • the invention features a backhoe bucket of the type including two sections attached for relative pivotal movement-and a pair of hydraulic actuators for pivoting the sections relative to each other, the bottoms of the two sections overlapping when they are in their relatively closed position.
  • the actuators with their lines of force substantially in line with the sides of the bucket, providing cutting 'means at the leading and trailing edges of the front section and the leading edge of the rear'section, forming each side of each section to define a concave surface facing the other section and each side of one of the sections to define a convex surface adjacent the concave surface, and arranging the actuators. for. pivoting the sections relatively through an arc of not less than 90.
  • the second aspect features a materials handling attachment for connectionby engagement with the exca-- vation bucket of the type including first and second sections, each having two sides and a bottom, mounted for pivotal movement relative to each other between a relatively closed and a relatively open position, the attachment comprising a materials handler, and an attacher rigidly connected to the handler, the attacher 2 including two pairs of generally oppositely facing engagement surfaces adapted for respective surfaces the sections in face-to-face engagement, said pairs being generally perpendicular to each other.
  • the attacher includes a pair of transversely spaced side members each of which defines a recess for receiving a bottom edge of one bucket section, and a'pair of cross members extending between and rigidly connected to the side members, one of the cross members defining a pair of oppositelyfacing engagement surfaces arranged for respective face-to-face engagement with facing bottom edges-of v respective bucket sections.
  • FIG. 1 is a perspective view of a bucket constructed according to the present invention in its closed operative position
  • FIGS. 2 and 3 are perspective views of the bucket of FIG. 1 in'open operative position
  • FIG. 4 is a transverse sectional view of the bucket of FIG. 1 operating as .a clamshell;
  • FIGS. 5 and 6 are perspective views of other buckets constructed according to the present invention.
  • FIG. 7 is a perspective exploded view, partially in section, of an attachment.
  • FIG. 8 is a sectional view of the attachment of FIG. 7 secured to the bucket of FIG. 1.
  • FIGS. 1-4 there is 7 45 the bottom rear edge 23 and bottom front edge 21 of portion 16.
  • Conventional teeth 24 are mounted on plate 27 along front edge'21.
  • a cylindrical crossbar 28
  • Rear section 14 similarly has generally triangular spaced side walls 32, 34 joined by a curved, laterally extending rear and bottom wall 36 and a cylindrical crossbar 37, and includes additionally an upper mount- .ing plate 38 welded along its edges to the top' edges of mouth of front section 16 so that the rear section will pass partially within said front section when bucket 10 is in-the closed operative position as shown in FIG. 1.
  • the leading edges 33 of side walls, 32, 34 of rear section 14 are concave.
  • the trailing edges 19 of side walls 18, 20 of front section 16 are S-shaped; the upper portion of each edge being, viewed from the rear, convex and the lower portion being concave.

  • brackets 42 is pivoted to dipper stick 12 by a hinge pin 44.
  • the center of brackets 42 is pivotally attached to the adjacent end of a link member 48, the other end of the member 48 being pivotally attached to links 50 by hinge pin 49.
  • the other ends of links 50 are connected by hinge pin 51 to dipper stick 12 at a point spaced from pin 44.
  • the piston rod 52 of a hydraulic actuator 53 (for swinging bucket relative to dipper stick I2) is connected to hinge pin 49 connecting link member 48 and links 50.
  • a second hydraulic actuator 54 is connected between the end of brackets 42 most distant from pin 44 and ears 30 of crossbar 28 of front section 16. As shown most clearly in FIG.
  • actuator 54 is arranged with maximum hydraulic force available for opening the bucket sections, with the cylinder end 56 of actuator 54 detachably attached to a hinge. pin 58 and the end of the actuator piston rod 60 fixed to a member 62 extending between ears 30 and pivotally attached to ears 30 by pin 61. Of course, the actuator may-be reversed.
  • the elongated portions of ears 30 overlie opposite sides of and protect piston 60.
  • the substantial overlap of the sides and bottoms of sections Hand 16 permits the working capacity of the bucket to be varied. Additionally, the overlap of the section bottoms, and the relatively concave configuration of the adjacent section side walls enable the bucket firmly to grasp objects, such as log L shown in FIG. 4.
  • FIGS. 1-4 wherein hydraulic actuator 54 is located within sections 14,16 is especially suitable for narrow buckets of relativelysm'all capacity.
  • larger buckets of increased width bucket 10" in FIG. 5 and bucket 10" in FIG. 6 may be constructed by mounting a pair of actuators exteriorly of the sections, straddling dipper stick 12.
  • the construction of buckets 10' and 10" is in many respect substantially identical to that of bucket 10. Similar portions of these latter buckets are identified by the same'reference numerals as the corresponding parts of bucket 10, with differentiating primes or double primes added as appropriate.
  • the major respects in which the construction of the various buckets differ is pointed out hereinafter.
  • bucket 10' comprises complementary front and rear sections, 16 and 14' respectively, det'achably pivotally connected to each other by a hinge pin 15'.
  • a pair of hydraulic actuators 54 are provided on top of upper mounting plate 38 of rear section 14', one-actuato'r54' being mounted on the exterior side of each of brackets 42.

  • Side walls 18, 20' of from section 16' extend above hinge pin 15', and the end of the piston rod of each actuator 54' is attached, by hinge pins 70, to the adjacent one of side walls 18, 20 above the pivotal axis of pin 15'.
  • Bucket 10 (FIG. 6) similarly includes a pair of hydraulic actuators 54" on top of upper mounting plate' tuator 54" is attached, by hinge pins 72, to the adjacent one of side walls 18", 20"-below pins 80.
  • attachments such as backfill attachment 90
  • attachment includes a conventional backfill blade 92 to which an attachment mount, designated 94, is welded.
  • mount 94 comprises a pair of transversely-spaced sides, generally designated 96, 98 and which are mirror images of each other, joined by transversely extending cylindrical cross brace 100 and rear latch plate 102.
  • Each side includes an upper plate 97 overlapping and welded adjacent its lower edge to the inside of a lower plate 99.
  • each lower plate is an inwardly turned reinforcing flange 101.
  • Reinforcing corner 7 plates 104 are welded to latch plate 102 and one of side plates 99 at the inside of the rear corners defined by the latch plate and the respective one of the side plates.

  • an upwardly facing mounting surface 112 defined by the upper edge of plate 99, extendsfrom'a point at the rear and midway the height of slot 110 to latch plate 102.
  • a downwardly facing surface 1 1 defined by the lower edge of plate 97, extends forward from a point slightly forward of the front edge 109 of surface 112 and defines the top of slot 110. The portion of plate 97 to the rear of surface 111 diverges sharply away from surface 1 12.
