Definitions

  • the present invention relates to a gravel dumper.
  • Earth excavators having two jaws hinged to a frame around parallel axes and spaced apart from each other, these buckets being suspended from a machine such as crane, truck, construction machine, earthmoving machine.
  • the jaws are controlled by one or more jacks housed in the frame.
  • the present invention relates to an earth moving bucket comprising a rigid chassis suspended from an earthmoving machine, a main cylinder housed in the chassis, two symmetrical jaws controlled by the main cylinder, capable of moving between open positions. maximum and complete closure, each jaw being carried by two parallel suspension arms pivoting on the frame about the same axis of suspension, these two axes being parallel and spaced from each other on the frame, each jaw being articulated, at the lower end of its suspension arms, on a pivot axis parallel to the suspension axes, and connected to maneuvering arms controlling tilting movements of the jaw on its pivot axis during a maneuver opening or closing the bucket, characterized in that each jaw is composed of two different rigid parts, a receptacle and a shovel, each with a base and a sole or a toothing, these two jaw parts, being hinged one on the other and on the suspension arms, about said pivot axis, and being further separately connected to the operating arms of the jaw, the shovel by a direct articulation to its
  • the Fig. 1 shows the main constituents of the bucket.
  • a rigid frame 1 in the form of a trapezoidal prism is provided on its upper side with hydraulic feed members 2 and hooking members (not shown) for connecting the bucket to a control arm of a machine such as truck, crane or construction machine according to the usual technique.
  • This frame is equipped in the lower corners of its structure with two axes 3 parallel and perpendicular to its end faces, these axes being embodied by pivoting members such as bearings or shafts, or provided with reinforcing elements that it does not have. is not necessary to describe here.
  • the axes 3 are suspension axes on each of which pivot the upper ends of two suspension arms 4.
  • the frame thus carries two pairs of suspension arms which are arranged on each of its front faces, are parallel and slightly curved towards the center .
  • a robust tubular member 5 which connects the arms of the pair rigidly to each other and also performs a stop function as will be seen later .
  • the two suspension arms 4 of each pair carry articulation members 6 which will be detailed below, which are coaxial, define a pivot axis 7 parallel to the axes 3 and ensure the suspension of one of the jaws 8 of the bucket on the common axis of the bodies 6, while allowing its pivoting.
  • arms 9 are arranged in the vicinity of each of the suspension arms 4. These are four actuating arms, ie two per jaw 8 placed on the outer faces of the jaws.
  • This jack is housed inside the frame 1 in a longitudinal position. This is, in the embodiment shown, a hydraulic cylinder with a cylinder 11 in which slides a rod 12. It will be controlled by the extension or withdrawal by the operator of the bucket.
  • a hydraulic cylinder with a cylinder 11 in which slides a rod 12. It will be controlled by the extension or withdrawal by the operator of the bucket.
  • At the end of the rod 12 and on the bottom of the cylinder 11 are mounted members which materialize at these two locations two hinge pins 13 perpendicular to the faces of the chassis and therefore parallel to the suspension axes 3 and pivoting 7.
  • the jack 10 is connected indirectly to the frame 1.
  • Two coordination bars 18 are each articulated, at one end, on one of the pins 13 and are connected at their other end by a tie rod 19 whose central portion is hinged itself in the center of the side face of the frame 1 by a hinge 20.
  • This indirect connection between the frame and the jack allows the latter to move according to the regime of forces imposed on the rod 12 and the cylinder 11 of the cylinder 10.
  • the Fig. 1 shows the maximum extension position of the cylinder 10, the two jaws 8 being pressed against each other, in the fully closed position.
  • the Fig. 2 shows the maximum contraction position of the cylinder 10, the two jaws being open symmetrically, and the Fig. 3 shows an intermediate position in which the jaws are in asymmetrical positions. Note that in this position, the cylinder 10 is shifted in the frame relative to its normal position.
  • the jaws 8 are composed of two rigid parts hinged to one another along the pivot axis 7 common to these two parts and the suspension arms 4. Comparing the jaws 8 left and right on the Fig. 3 it can be seen that the two parts of the right jaw made relative pivoting of limited amplitude with respect to each other, while the left jaw moved as if in one piece. The two moving parts will be called then a receptacle 8a and a shovel 8b.
  • the receptacle 8a comprises ( Fig.
  • the shovel 8b has for its base 25a a curved bottom 25 extended by a knife 26. It is equipped with teeth 27. Side walls 28 of the base 25a engage inside the walls 22 of the receptacle and are reinforced at the level of the pivot axis 7 by V-cut plates 29.
  • the plates 29 have an extension which, as can be seen in FIGS. figs 3 and 4 carries a hinge ring 30 of the shovel 8b to the operating arm 9.
  • Another pair of hinge rings 31 integral with pivot axes connects curved rods 32 having a head-like extension to the flanks 22 of the receptacles. .
  • the heads of the rods 32 are engaged in lateral notches of the operating arms 9.
  • the axes of articulation of the rings 6, 30 and 31 are aligned with the left jaw and form a broken line at the right jaw, resulting from a relative rotation of the two jaw parts, due to displacements. differentiated arms 4 and 9 during the control of the cylinder 10 between the positions of figs 2 and 3 .
  • the bucket control device still has a second jack 34 whose cylinder is mounted on the hinge axis 13a common to the rods 16 and 17 for the same purpose as that disclosed in the patent. EP 0256304 but whose effect is exerted mainly on the receptacle portion 8a of the jaws.
  • This auxiliary jack 34 may be spring loaded or hydraulic. If necessary, it can be connected to the cylinder 10 and controlled from the machine carrying the bucket. As a reminder, the flanks 22 of the jaws 8 are cut with a deep indentation whose radius corresponds to that of the robust tube 5 incorporated in the suspension arms 4.
  • the Fig. 6 still shows an additional element of the dumpster. It is an inner scraping device 36 which equips the receptacle 8a of each of the jaws 8.
  • This device comprises a curved plate 36a integral with two L-shaped transverse arms 36b which can be hooked to integral inner nipples 36c. inner faces of the walls 22 of each receptacle 8a.
  • a central arm 36d with a hinge 36e can be hung on the jack 34.
