Definitions

  • the present patent application for industrial invention relates to a utility vehicle mainly used on construction sites, intended either for digging, or for transport over short distances or for the unloading of inert materials (earth, gravel, pedestal, sand ... ), characterized by the widest possible range of universal joints available to the bucket, which can thus act either as a mechanical shovel or as a tipping bucket with a front tilting adjustable height.
  • inert materials earth, gravel, pedestal, sand ...
  • the bucket can therefore be stopped at any height and can therefore tilt forwards to perform unloading in the case of the raised bucket or, in the case of the lowered bucket to perform the frontal clearing on the ground.
  • the present invention therefore makes it possible, with the moven of a single machine, to carry out a series of operations, either of loading, or of transport, or of variable height unloading of inert materials, operations which hitherto required the use of various specific equipment, such as mechanical shovels and dumpers with reverse variable height front.
  • Drawing No. 1 is a side view of the machine according to the invention with the bucket in the rest position which is also the running position of the machine.
  • Drawing No. 2 is a side view of the machine according to the invention with the bucket lowered to the ground.
  • Drawing No. 3 is a side view of the machine according to the invention with the bucket raised to its maximum height and not overturned frontally.
  • Drawing No. 4 is a side view of the machine according to the invention with the bucket raised to its maximum height and also overturned frontally.
  • Drawing No. 5 is a top view of the machine according to the invention with the bucket lowered forward to the ground and overturned frontally until it lands on the ground itself.
  • the bucket itself consists of a body (1), which has an almost triangular cross section, provided with three attachment points, which consist of pairs of trunnions, two of which are symmetrical (1a) placed below the body and the third, intermediate (1b) is projecting externally along the rear edge of the body itself.
  • Each angle bracket “L” (2) pivots, from the terminal part opposite the end of a horizontal pivot (4) on which are fixed two flails (5) op placed and slightly spaced, which together form a single lever, capable, at the opposite end on a horizontal pivot (6) provided on the chassis, formed by two identical and opposite plates (7), spaced in it in the measure which allows them to contain exactly the pair of plagues (5) above.
  • Such a chassis is therefore fixed by hinges on a horizontal pivot (8) bordering on the outside at the top of a long lifting arm (9) supported at the base on a supporting structure (10) securely attached to the chassis of the contraption.
  • each pair of plates (7) are integral with a spacer (11) which has in the center line, two pins (11a), between which is attached a tie rod (12), pivoted at the other end , to the aforementioned supporting structure (10), so as to allow the latter to function as a chassis in an articulated quadrilateral which is made up of two rockers, respectively constituted by the pair of arms (9) and by the tie rod (12 ) as well as by a connecting rod, composed of two plate chassis (7) joined by the spacer (11).
  • the pair of arms (9) can pivot relative to the chassis (10) thanks to the action of a hydraulic cylinder (13), the chamber of which pivots on the supporting structure (10) and the rod (13) of which is attached in the middle of the spacer which unites the two arms (9).
  • rockers (3) pivoted at one end to the lower journals (la), as already described, pivot at the opposite end, to a pivot (14), fixed between each pair of plates (7) and to which the rod (15a) of a hydraulic cylinder is attached, the chamber (15) of which is voted horizontally, in the tilting position, inside and at the mid-length approximately of the pair of rods (5) above.
  • the plates (7) are found to act as a frame in an articulated quadrilateral which consists of two rockers, which consist respectively of the double rods (5) and the rod (3) as well as 'a connecting rod formed by the square at "L" (2).
  • the "L” brackets (2) are integral with a spacer (16), in the center line of which horizontally pivots a hydraulic cylinder (17), the rod (17a) of which is attached to the pair of pins (1b), on the rear part of the body.
  • the position drawn with a continuous line in drawing No. 2 is obtained by starting from the rest position or the operating position of the machine, by simply actuating the hydraulic cylinders (15) until their complete contraction.
  • the positions indicated by means of a hatched line in drawing No. 2 correspond, on the contrary, to two particular positions of the bin not overturned frontally: in one case, the front edge of the front wall of the body coincides with the ground, ie in the front load position by crawling, while in the other case, the front edge of the bucket is pressed into the ground, position suitable for a hollow frontal.
