Definitions

  • the invention relates to a machine for dig and / or clean a ditch and a machine equipped with a such machine.
  • Such a machine sometimes referred to as a "rotary slicer” »Is used in agriculture for land drainage and irrigation and in the roads for sanitation of the edges of road.
  • French patent 1,604,301 describes such a machine which includes a support frame from which is suspended a rotating element or “dragante wheel” of which rotation makes it possible to conform a ditch.
  • Such a device gives satisfaction under certain conditions of use.
  • a ditch is not always straight and it is sometimes difficult for the driver of an equipped vehicle of a known machine to follow the layout of an existing ditch or create a ditch according to a predetermined curved path.
  • a machine conforming to FR-A-1 604 301 is installed on the back of an agricultural tractor, turning the tractor to the left has the effect of shift the dragging wheel of the machine to the right, this which can lead to inaccuracies in the plot obtained for the ditch.
  • the depth of a ditch must be able to vary depending on its intended use and / or the nature of the ground.
  • the invention relates to a machine for dig and / or clear a ditch that includes a rotating member shaping the ditch suitable for being driven by a machine and supported by a structure mounted on this machine and which includes two primary arms capable of being articulated to the level of their respective first ends by relation to the craft, essentially extending in two directions generally parallel and whose seconds respective ends are connected by a connecting rod articulated on these arms, and a secondary arm articulated on the second end of a primary arm and on which is mounted the rotary member.
  • This machine is characterized by what one of the primary arms and the secondary arm contain rotating drive elements from the rotary member and in that at least one of the arms primary is adjustable in length so that the offset of the rotary member relative to the machine is adjustable.
  • the two primary arms, the part on which they are articulated and the connecting rod constitutes a generally deformable structure in the form of regular or irregular parallelogram, the character possibly irregular from this parallelogram arising basically of the adjustable length of one of these arms.
  • This parallelogram-like structure deformable regular or irregular allows to move vertically the second arm and the rotary member which it supports, which allows you to adjust the depth of a ditch shaped thanks to this machine.
  • the adjustable character in length of one of the primary arms allows to adjust the offset of the rotary member relative to the machine on which is mounted the machine, which facilitates the control of such machine.
  • the invention also relates to an agricultural machine, roads or civil engineering equipped with a machine such as previously described.
  • An agricultural tractor T is shown in Figures 1 to 5 digging a ditch F in the ground S.
  • the tractor T is equipped with a machine 1 which includes a plate 2 intended to be mounted at the rear of the T tractor being attached to it by any suitable means.
  • plate 2 is equipped with an extension 21 receiving a pawn 3 intended to cross an ear, adapted and not shown, provided on the tractor T.
  • the plate 2 is dimensioned and configured so that it can be mounted on the tractor T in a position such that a point A 1 is generally aligned with a power take-off provided at the rear of the tractor T.
  • This point A 1 is the geometric center of articulation on the plate 2 of a box 4 of generally parallelepiped shape and elongated and inside which is arranged a chain 41 shown partially only in Figures 1 and 7.
  • the box 4 has a generally rectangular shape, as shown in FIG. 7.
  • a connecting rod 7 is disposed between the ends 43 and 62. More specifically, the connecting rod 7 is articulated at a point of articulation B 2 on the end 62 of the bar 6, while the connecting rod 7 is centered on an axis Y 1 -Y ′ 1 , the trace of which in the plane of FIG. 1 is the point of articulation B 1 .
  • the connecting rod 7 is crossed, at the level a first end 71 by a bolt 8 which constitutes an axis of articulation between the elements 6 and 7.
  • the connecting rod 7 On the side opposite its end 71, the connecting rod 7 is secured to a sleeve 91 pivotally mounted around a tube 44 which is itself secured to the box 4 and centered on the axis Y 1 -Y ' 1 .
  • the connecting rod 7 can rotate around the axis Y 1 -Y ′ 1 , the bridge B 1 representing its point of articulation around this axis in the plane of FIG. 1.
  • a second box 9 is integral with the sleeve 91 and contains a chain 92 shown partially only in Figures 1 and 7.
  • This chain 92 allows to rotate, in the direction of the arrow R in FIG. 1 a rotary member 10 provided with blades and which can be called “dragante wheel”.
  • a deflector 11 is mounted near the dragging wheel 10 and allows to direct the rubble extracted from the ditch F by the dragging wheel 10 in the direction of the arrow G, because of the rotation R of the wheel 10.
  • X 3 -X ' 3 the longitudinal direction of the box 9.
  • X 4 -X' 4 the longitudinal direction of the connecting rod 7, that is to say the radial direction relative to the axis Y 1 - Y ' 1 which passes through the bolt 8.
  • the directions X 3 -X' 3 and X 4 -X ' 4 are mutually parallel and parallel to the plane of Figure 1, so that their projections in this plane are combined.
  • a jack 12 is mounted on a lug 45 provided on the box 4, while being articulated on this lug 45 while its rod is articulated, by means of a screw 13, at a point A 3 of the plate 2.
  • the length of the box 4 and in particular the distance between the points A 1 and B 1 in Figure 1 is fixed, which is in particular imposed by the fact that it contains the chain 41 used to drive the wheel 10 in rotation.
  • the length of the box 9 is constant, which means that the distance between the point B 1 and the center C 1 of rotation of the wheel 10 in FIG. 1 is also constant.
  • D a straight line passing through the points of articulation A 1 and A 2 in FIG. 1.
  • a 1 a horizontal straight line passing by point A 1 in FIG. 1.
  • ⁇ the angle that the line D makes with respect to the line D 'when the tractor T rests on a horizontal ground. This angle is 45 ° and can, in practice, have a value between 40 and 50 °.
  • a structure for supporting the dragging wheel 10 by compared to plate 2 comprising two primary arms respectively constituted by the box 4 and by all of elements 5 and 6.
  • This structure also includes a secondary arm constituted by the box 9, this arm itself being supported by one of the primary arms, while the connecting rod 7 connects the ends 62 and 43 of the primary arms distant from the plate 2.
  • the depth P of the ditch F is relatively small since the primary arms constituted respectively by the box 4 and by the elements 5 and 6 are lifted by the jack 12 and rotate respectively around the points A 1 and A 2 , as shown by the arrows F 1 and F 2 . Conversely, if the cylinder 12 is contracted, the primary arms rotate respectively around the arms A 1 and A 2 as shown by the arrows F ' 1 and F' 2 in Figure 3, so that the depth P '' of the pit F thus created is increased.
  • the actuator 5 is adjusted so that the cumulative length of the elements 5 and 6 is equal to the distance between the points A 1 and B 1 , so that the points A 1 , A 2 , B 1 and B 2 define a deformable parallelogram.
  • the rotations along the arrows F 1 , F 2 , F ' 1 and F' 2 have the effect of moving the center C 1 of the wheel 10 in a vertical direction ZZ 'when the surface of the ground S is horizontal.
  • ⁇ the offset of the dragging wheel relative to the PTO of the tractor T, that is to say the horizontal distance separating the points A 1 and C 1 .
  • the offset ⁇ can be increased up to a value ⁇ 'by contracting the jack 5. It is on the contrary possible to reduce this offset to the value ⁇ ''by deploying the jack 5, so that the distance between points A 2 and B 2 is increased.
  • a solid axis 14 is supported by two bearings 15 and 16 respectively provided in the boxes 4 and 9, while two pinions 17 and 18 are mounted at the respective ends of the axis 14 and immobilized by two nuts 17 a and 18 a .
  • These sprockets are intended to cooperate with the chains 41 and 92 respectively.
  • the bearings 15 and 16 allow a movement of rotation of the axis 14 relative to the tube 44, which allows transmission of movement from chain 41 to chain 92, with a view to driving the wheel 10.
  • the tube 44 is connected to the main part of the box 4 thanks to a weld bead 46.
  • a second bead of solder 47 connects the tube 44 to a flange 48.
  • the sleeve 91 is connected to the box 9 by a weld bead 96 and to the flange 7 by a second weld bead 97.
  • Bolts 19 passing through oblong slots provided in the flange 48 make it possible to ensure the relative positioning of the boxes 4 and 9 along the axis Y 1 -Y ′ 1 , with a possibility of rotation linked to the sliding of the tube 44 inside the sleeve 91, this being possible thanks to the oblong nature of the lights provided in the flange 48.
  • the bolts 19 could be replaced by a nut mounted on the end of the tube 44 introduced into the box 9, this end then being threaded.
  • the invention has the particular advantage that the structure formed of elements 4 to 9 is compatible with the transmission of power to the dragging wheel 10, by means chains 41 and 92, while being adjustable.
  • the two primary arms 4 and 5-6 can be adjustable in length, measures are then taken so that this possibility of adjustment to be compatible with training in rotation of the wheel 10.
