Definitions

  • the subject of the invention is a device for attaching a tool to a machine, in particular a construction or agricultural machine.
  • a machine in particular a construction or agricultural machine.
  • excavation or material removal equipment on the market, such as excavators, loaders, backhoes, etc.
  • you have to change tools, such as shovel, bucket, router, etc.
  • Modern machines have automatic devices for quickly changing tools. These devices only work for suitable tools which, if we want to transform an old machine into a machine allowing the automatic change of the tool, implies a change of all the tools.
  • the object of the invention is to provide a device for fixing a tool to a machine, which can be adapted to any machine without changing the tools.
  • FIG. 5 represents the end of an arm 25 of a backhoe nant such a device.
  • the invention is described for a bucket 26, it is clear that it can be used for any tool intended to be fixed on the arm of a construction machine or other machine.
  • the arm 25 of the machine comprises two connecting rods 27 articulated on the arm. Between these connecting rods are articulated the rod 24 of a control cylinder (not shown) and a connecting member 28.
  • the bucket 26 is articulated at point 20 on the arm and at point 19 on the connecting member 28. Which, in order to change the bucket 26, requires having to remove the pins 19 and 20.
  • This system is replaced by a device according to the invention in the following manner: - A female element 9 is fixed on the arm 25 of the vehicle articulated on the existing axis 25 and is fixed articulated to the connecting member 28. This manner of doing does not require any modification of the vehicle.
  • This female element is permanently fixed to the machine.
  • a male element 1 is permanently fixed to the bucket 26 by bolts in the existing fixing holes 17 and 18.
  • a male element 1 is permanently fixed to all the tools constituting the series of tools intended to be used with the machine.
  • a male element M comprises a steel base plate 1 on the upper face of which are welded triangular steel sections so as to constitute a V.
  • the V is in a horizontal position and the tip of the V is turned to the left.
  • the section of the profile constituting the V is an isosceles right triangle which is welded by one of the vertices 4 of its base 22 on the plate 1.
  • the triangle constituting the profile is arranged with a small side 3 , constituting one side of the right angle and the interior of the V, perpendicular to the plate 1 and the other short side 2, constituting the other side of the right angle and the upper face of the V, parallel to the plate 1 remote from the latter.
  • the V therefore appears on the base plate 1 like the front of a boat having the outer sides inclined at 45 °.
  • On the underside of the plate are welded, symmetrically with respect to the axis of symmetry of the male element M, two plates 7 having circular holes 17 and 18 (see FIG. 4) so as to allow the fixing of the element M on a tool.
  • the base plate 1 has a circular hole 5 located in front of the point V. This hole 5 has a reinforcement 6 and is intended to receive a fixing pin shown by its axis 21.
  • FIG. 2 we see a female element F.
  • This element comprises a steel base plate 9 similar to the base plate 1 of the male element M.
  • On the upper face of this plate 9 are triangular sections welded in steel so as to constitute a V.
  • the V is in a horizontal position and the point of V is turned to the left.
  • the section of the profile constituting the V is an isosceles right triangle which is welded by one of the vertices 11 of its base 23 on the plate 9.
  • FIG. 2 we see a female element F.
  • This element comprises a steel base plate 9 similar to the base plate 1 of the male element M.
  • On the upper face of this plate 9 are triangular sections welded in steel so as to constitute a V.
  • the V is in a horizontal position and the point of V is turned to the left.
  • the section of the profile constituting the V is an isosceles right triangle which is welded by one of the vertices 11 of its base 23 on the plate 9.
  • the triangle constituting the profile is arranged with a small side 10, constituting one side of the right angle and the outside of the V, perpendicular to the plate 9 and the other short side 12, constituting the other side of the right angle and the upper face of the V, parallel to the plate 9 distant from it.
  • the V therefore appears on the plate as a snow plow triangle with straight sides with a space inside the V having faces inclined at 45 °.
  • element M element F comprises on its underside welded symmetrically with respect to the axis of symmetry of element F, two plates 15 having circular holes 19 and 20 so as to allow the fixing of the element F on a machine (see Figure 5).
  • the base plate 9 also has a circular hole 13 located at the tip of the V. This hole 13 has a reinforcement 14 and is intended to come into alignment opposite the hole 5 of the male element M, when the two elements are assembled, so as to allow the passage of an axis or a spindle.
  • the operation of the device for any tool change on a machine equipped with such a device is as follows: - The pin 21 is removed from the holes 5 and 13, respectively of the male element M and the female element F. - The tool is disengaged by removing the V from the male element from the V from the female element. - Another V of a male element fixed on another tool is introduced into the V of the female element fixed on the machine. - The pin 21 is inserted in place in the holes 5 and 13 of the two elements and is held in place by a security.
  • the maneuver is simple and can be carried out in a very short time.
  • This device is very simple to manufacture and can be produced for many types of machines. It will suffice to make a female part for each type of machine and as many male parts as the machine has tools.
  • this device prevents movement of the tool on the machine. Indeed, the two elements M and F once assembled have no play, because the two faces at 45 ° bear against each other. The 45 ° angle was chosen to allow good transmission of forces.
