Definitions

  • the present invention relates to a multipurpose combined screening and/or mixing bucket.
  • buckets are currently commercially available; in particular, one type of bucket, adapted to be mounted mainly on earth-moving machines known as power loaders, extends predominantly at right angles with respect to the loading direction and has grilled walls adapted to form a screen.
  • An equally grilled cover is articulated to the structure of said bucket and is adapted to close the loading space.
  • the assembly is rotatable about a longitudinal motorized axis.
  • This bucket is used mainly for screening aggregates at the pebbly shores of rivers and/or streams.
  • buckets of the above described type entail some drawbacks, among which there is the fact that they are configured for use, as mentioned, on power loaders, which are conventionally earth-moving machines in which the excavation and loading element is not articulated about a vertical axis, such machines being therefore operationally limited.
  • this aspect is particularly onerous.
  • a multipurpose combined screening and/or mixing bucket has been devised, which is the subject of Italian patent application no. PD 94 A 000145 filed August 5, 1994, in the name of VACCARO Tiberio; said bucket comprises a structure that forms the walls of a loading inlet provided with means for coupling to an earth-moving machine, with which a motorized rotating drum is associated in a rearward region, said drum being arranged so that its axis is parallel to the loading direction.
  • the bucket is inclined with respect to the horizontal and this causes the material contained therein to be arranged, due to the effect of gravity, partly on the bottom, which by being solid does not contribute to screening, and partly on a limited portion of the grilled side wall of the drum that can be identified as a lower region thereof that is adjacent to the bottom.
  • the area affected by screening is therefore not particularly large, and this increases the time required for the operation.
  • drum movement elements are located axially inside said drum, and this prevents complete loading and therefore optimum performance in operation.
  • a principal aim of the present invention is to provide a multipurpose combined bucket that eliminates the drawbacks described above of conventional buckets.
  • an object of the present invention is to provide a bucket that can be conveniently installed on earth-moving machines with an articulated arm commonly known as excavators.
  • Another object of the present invention is to provide a bucket that provides high efficiency in screening, with a considerable reduction in the time required by the operation.
  • Another object of the present invention is to provide a bucket that is extremely flexible both from the production and from the operating points of view.
  • Another object of the present invention is to provide a bucket that is characterized by lower production and maintenance costs with respect to conventional buckets.
  • Another object of the present invention is to provide a bucket that can be produced with conventional technologies at competitive prices.
  • a multipurpose combined screening and/or mixing bucket comprising a structure that forms the walls of a loading inlet, with means for coupling to an earth-moving machine, to the rear whereof a motorized rotating drum is associated, said drum being arranged so that its axis lies parallel to the loading direction, said bucket being characterized in that said drum is rotatably supported at the rear in a cantilevered manner by a center bearing associated with said structure by supporting means.
  • a multipurpose combined screening and/or mixing bucket according to the invention is generally designated by the reference numeral 10.
  • the bucket 10 comprises a structure 11 that forms the walls of a loading inlet 12 provided with means, described hereinafter, for coupling to an earth-moving machine that is not illustrated herein.
  • a drum 13 is associated with the structure 11 in a rearward position and is provided with a solid bottom 14; said drum is rotated by a drive unit, not shown, and is arranged so that its axis lies parallel to the loading direction.
  • the drum 13 is supported axially and rotatably in a cantilevered manner at the rear by a center bearing 15 which is rigidly associated with said structure 11 by supporting means described hereinafter.
  • Said structure in this embodiment, is constituted by elements arranged so as to form a quadrilateral: an upper element 16, provided with coupling means that in this case are constituted by two parallel plates 17 provided with coupling holes 18; two lateral elements 19 that are substantially plate-like; and a lower blade 20 that is provided, again in this case, with teeth 21 associated with its free edge.
  • said supporting means comprise a plate-like element 22 to which the center bearing 15 is fixed.
  • the plate-like element 22 is provided with an annular wall 23 that is in turn fixed, in this case by welding, to the ends of two tubular elements 24 the other end whereof is fixed, again by welding, to rearward regions of the upper element 16.
  • the supporting means furthermore comprise a supporting element 25 that is fixed to the annular wall 23 on the opposite side with respect to the tubular elements 24 along a horizontal axis, relative to the bucket 10; said supporting element is provided, at a median region 26, with two wings 27 having respective free ends 28; each end is stably connected to the ends of a corresponding tie rod 29, the other end 30 whereof is stably connected to a corresponding lateral element 19.
  • each one of the tie rods 29 are respectively connected to the corresponding lateral element 19 and to the corresponding wing 27 by threaded elements 31.
  • the drum 13 is provided with a spacer mesh 32 that is perimetrically fixed to the side walls of said drum 13 and lies parallel with respect to the bottom 14.
  • the spacer mesh 32 is spaced from the bottom 14, so as to increase the screening surface, consequently increasing efficiency and reducing the costs of the operation.
  • the bucket according to the invention provides structural simplicity combined with an overall strength and considerable operating functionality.
  • the presence of the spacer mesh in fact causes the material contained in the drum to be arranged not only at part of the lateral grilled surfaces but also on part of the spacer mesh which, in turn, in addition to contributing directly to the screening operation, also causes part of the lateral grilled surface provided between said mesh and the bottom to become active.
