Definitions

  • the present invention relates to a quick mount particularly for fixing buckets to earth-moving machines.
  • Two operators are furthermore always required to perform the mount: one for maneuvering the earth-moving machine, the other one for inserting said dowels.
  • the aim of the present invention is to eliminate the disadvantages described above in the known art by providing a quick mount capable of achieving the substantially immediate replacement of buckets of various sizes and kinds on earth-moving machines.
  • a consequent primary object is to provide a quick mount, particularly for fixing buckets to earth-moving machines, which allows the machine operator to perform the replacement operation autonomously.
  • Another important object is to provide a quick mount characterized by easy use and complete absence of maintenance.
  • Another object is to provide a quick mount which can be easily installed and adapted to current earth-moving machines and to current kinds of buckets.
  • Not least object is to provide a quick mount which can be manufactured at low costs with current production systems.
  • a quick mount particularly for fixing buckets to earth-moving machines, characterized in that it comprises a support which is fixable to the end of the operating arm of an earth-moving machine, elements with a curved end extending downwards from said support on one side, said curved end being adapted to insert between the upper portion of a bucket and a transverse coupling pivot thereof and, on the opposite side, means for coupling to the bucket.
  • a quick mount according to the invention is generally indicated, in a first embodiment, by the reference numeral 1 and comprises a support constituted by a metallic plate 2; two first parallel wings 3, made of thick sheet metal, are upwardly and longitudinally welded orthogonally to said plate; said wings are provided, at their ends, with coaxial pairs of transverse holes 4 and 5 for fixing to the operating arm of an earth-moving machine.
  • the end of the arm 6 is conveniently articulated between said holes 4, while the end of a lever system 7 actuated by a hydraulic piston 8 is articulated between said holes 5.
  • a half-shell 12 conveniently made by diametrically cutting a metal tube, is transversely welded between the two ends 11 of the elements 10.
  • a transversely perforated element 13 for the pivoting ot a tubular element 14 is upwardly welded in a substantially orthogonal position at the end of each second wing 9 which is arranged opposite to the articulation of the arm 6.
  • the rotoidal coupling between the pair of elements 13 and the tubular element 14 is achieved by inserting, in appropriate end seats of said element 14, elastic means 15 of the kind commonly termed “silent block” and by then inserting axially to said elastic means a threaded pin 16 provided with a locking nut.
  • a hook 17 is welded radially to said tubular element 14; said hook is substantially composed of a metal plate 18 which has a metal strip 19 welded to its free end on its outer side; said strip has an outer rounding 20 which in practice joins the two surfaces which are not adapted to be coupled.
  • Said hook 17 is kept arranged downwards and substantially orthogonal to said plate 2 as it is rigidly associated by means of bolts to an element 21 which protrudes downwards from said plate 2.
  • An elastic rubber element 22 is interposed between said hook 17 and the element 21; its compression allows said hook a certain degree of rotation about the pivot 16.
  • a bush 23 is transversely welded on the tubular element 14 in a position diametrically opposite to said hook 17; the end of a lever 24 can be inserted in said bush, said lever allowing the above mentioned rotation when manually actuated.
  • the quick mount 1 can be associated with the upper portion of a bucket 25 which is conveniently provided with a pair of third longitudinal wings 26 made of thick sheet metal, between which a large cylindrical pivot 27 is transversely welded on the side of said elements 10; the outer surface of said pivot 27 is shaped complementarily to the inner surface of said half shell 12.
  • a crosspiece 28 is welded to the bucket 25 on the side of said hook 17; said crosspiece is upwardly chamfered and downwardly shaped complementarily with respect to the coupling regions of said hook.
  • FIGS 3, 4 and 5 illustrate a first step of approach of the operating arm 6 to the bucket 25, with the mount 1 in a substantially vertical position due to the traction exerted on the lever system 7 by the hydraulic piston 8.
  • a second step consists in inserting the half-shell 12 between the pivot 27 and the upper part of said bucket 25.
  • the mount 1 By subsequently actuating the lever system 7 by means of the hydraulic piston 8, the mount 1 is rotated about the pivot 27 until the rounded portion 20 of the hook 17 makes contact with the chamfered portion of the crosspiece 28.
  • the crosspiece 28 forces the hook 17 to rotate about its articulation pivot until it stably engages.
  • a quick mount is generally indicated by the reference numeral 101 in a second embodiment, and comprises a support constituted by a metal plate 102 which can be fixed to the operating arm of an earth-moving machine; two first parallel wings 103, made of thick sheet metal, are longitudinally welded below said plate; an element 104 extends downwards from an end of each of said wings 103 and has an end 105 which is outwardly curved in the shape of an arc of a circle.
  • a half shell 106 is welded transversely between the two ends 105 of the elements 104.
  • the curved ends 105 are associable with the upper portion 107 of a bucket, not illustrated in the figures, and the portion 107 has a pair of second longitudinal wings 108 made of thick sheet metal, between which a large cylindrical pivot 109 is welded transversely; the outer surface of said pivot is shaped complementarily to the inner one of said half-shell 106.
  • the two first parallel wings 103 widen in the shape of a lug and have a pair of coaxial holes 110, between which a tubular element 111 is inserted and welded; said tubular element contains a double hydraulic cylinder 112.
  • the stems 113 of the cylinder 112 are coaxially screwed onto the bottom 114 of respective cup-like bushes 115 which are slidable between the outer walls of said cylinder 112 and the inner walls of the tubular element 111.
  • the cup-like bushes 115 are adapted to insert in tubular bushes 116 welded coaxially in holes provided on said pair of second longitudinal wings 108.
  • Said cylinder 112 is actuated by coupling to centrally located terminals 117 of a manual hydraulic pump, not illustrated in the figures, conveniently coupled to the support 102.
  • the various steps for mounting a bucket to an earth-­moving machine by means of the mount according to the second aspect of the invention consist in a first step of approaching the support 102 in a substantially vertical configuration, and then in a second step of inserting the half-shell 106 between the pivot 109 and the upper portion 107 of the bucket.
  • the support 102 is rotated about the pivot 109 until it rests against the upper portion 107 of the bucket, consequently arranging the double hydraulic cylinder 112 coaxial to the bushes 116.
  • the cylinder 112 is actuated, making the bushes protrude from the cup 115 and inserting them in the tubular bushes 116.
  • Said bushes are in fact subject to considerable wear, since they are heavily stressed during the use of the bucket.
  • the invention is furthermore composed of simple elements which can be mutually assembled without difficulty, and this makes it constructively convenient and competitive as regards its sales price.
  • the materials employed may be any according to the requirements.
