Definitions

  • the invention relates to a machine for digging and / or trenching a ditch and a machine equipped with such a machine.
  • Such a machine sometimes called “roto-slicer” is used in the field of agriculture for drainage and irrigation of land and in the field of roads for the sanitation of road edges.
  • the French patent 1,604,301 discloses such a machine which comprises a support frame from which is suspended a rotating element or "rolling wheel” whose rotation allows to form a ditch.
  • Such a device is satisfactory in certain conditions of use.
  • the distance between the ditch to be created or cleaned and the machine, such as a tractor, on which the machine is mounted is variable depending on the conditions of use of the machine. It is therefore necessary to provide different machine sizes with different offsets of the dredging wheel relative to the machine, in order to consider different applications.
  • a ditch is not always straight and it is sometimes difficult for the driver of a machine equipped with a known machine to follow the course of an existing ditch or to create a ditch along a predetermined curved path.
  • a machine complies with FR-A-1604301 is installed in the back of an agricultural tractor, turning the tractor to the left has the effect of deporting the dredging wheel to the right, which may lead to inaccuracies in the route obtained for the tractor. pit.
  • the depth of a ditch must vary according to its intended use and / or the nature of the soil.
  • a height adjustment of the rolling wheel takes place by rotating around it the PTO of the machine, the movement in height then inducing a parasitic movement in offset.
  • the invention intends to remedy more particularly by proposing a machine that can be reliably controlled and that makes it possible to create or cut ditches according to a predetermined pattern, with good precision, both with regard to horizontal geometry of the ditches as their depth.
  • the invention relates to a machine for digging and / or trenching a ditch which comprises a rotary forming member of the ditch able to be driven by a machine and supported by a structure mounted on this machine and which comprises two primary arms capable to be articulated at their respective first ends relative to the machine, extending substantially in two generally parallel directions and whose respective second 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 in that one of the primary arms and the secondary arm contain rotational driving elements of the rotary member and in that at least one of the primary arms is adjustable in length, so that 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 constitute a generally deformable structure in the form of a regular or irregular parallelogram, the possibly irregular character of this parallelogram essentially resulting from the adjustable length character of the one of these arms.
  • This structure in the form of a regular or irregular deformable parallelogram makes it possible to vertically move the second arm and the rotary member that it supports, which makes it possible to adjust the depth of a ditch conformed by this machine.
  • the adjustable length of one of the primary arms allows to adjust the offset of the rotary member relative to the machine on which the machine is mounted, which facilitates the steering of such a machine.
  • This adjustment can take place during the movement of the machine and the driver does not have to get off the machine to adjust the position of the rotary member or "dragging wheel", which facilitates its work.
  • the drive elements are protected in one of the primary arms and in the secondary arm, their operation is improved and a high power, necessary to dig a ditch, can be transmitted without problem through them.
  • the invention also relates to an agricultural machine, road or civil engineering equipped with a machine as previously described.
  • An agricultural tractor T is represented at Figures 1 to 5 digging a ditch F in the ground S.
  • the tractor T is equipped with a machine 1 which comprises a plate 2 intended to be mounted at the rear of the tractor T being fixed thereto by any appropriate means.
  • the plate 2 is equipped with an extension 21 for receiving a pin 3 intended to pass through 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 PTO provided at the rear of the tractor T.
  • point A 1 is the geometric center of articulation on the plate 2 of a box 4 of generally parallelepipedal and elongated shape and inside which is disposed a chain 41 partially shown only to figures 1 and 7 .
  • the box 4 has a generally rectangular shape, as is apparent from the figure 7 .
  • a connecting rod 7 is disposed between the ends 43 and 62. More specifically, the connecting rod 7 is articulated at a pivot point B 2 on the end 62 of the bar 6, whereas the connecting rod 7 is centered on an axis Y 1 -Y ' 1 whose trace in the plane of the figure 1 is the point of articulation B 1 .
  • the rod 7 is traversed at a first end 71 by a bolt 8 which constitutes an axis of articulation between the elements 6 and 7.
  • the rod 7 On the side opposite its end 71, the rod 7 is secured to a sleeve 91 pivotally mounted around a tube 44 itself secured to the casing 4 and centered on the axis Y 1 -Y ' 1 .
  • the rod 7 can rotate about the axis Y 1 -Y ' 1 , the bridge B 1 representing its point of articulation about this axis in the plane of the figure 1 .
  • a second box 9 is integral with the sleeve 91 and contains a chain 92 shown partially only to figures 1 and 7 .
  • This chain 92 makes it possible to drive in rotation, in the direction of the arrow R to the figure 1 a rotary member 10 provided with blades and which may be called "dragging wheel".
  • a deflector 11 is mounted near the rolling wheel 10 and directs the rubble extracted from the ditch F by the rolling wheel 10 in the direction of the arrow G, due to the rotation R of the wheel 10.
  • the longitudinal direction of the box 9 is denoted X 3 -X ' 3.
  • the longitudinal direction of the connecting rod 7, that is to say the radial direction with respect to the axis Y 1, is denoted by X 4 -X' 4.
  • Y ' 1 which passes through the bolt 8.
  • the directions X 3 -X' 3 and X 4 -X ' 4 are parallel to each other and parallel to the plane of the figure 1 , so that their projections in this plane are merged.
  • a jack 12 is mounted on a tab 45 provided on the box 4, being articulated on the tab 45 while its rod is articulated by a screw 13 at a point A 3 of the plate 2.
  • the length of the casing 4 and in particular the distance between the points A 1 and B 1 at the figure 1 is fixed, which is in particular imposed by the fact that it contains the chain 41 for driving 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 to the figure 1 is also constant.
  • D a line passing through the points of articulation A 1 and A 2 at the figure 1 .
  • box 4 is horizontal to the figure 1 the line D 'coincides with the direction X 1 , X' 1 .
  • ⁇ the angle that the line D with respect to the line D 'when the tractor T rests on a horizontal ground. This angle is equal to 45 ° and can, in practice, have a value between 40 and 50 °.
  • this structure comprising two primary arms constituted respectively by the box 4 and the set of elements 5 and 6.
  • This structure also comprises a secondary arm constituted by the box 9, this arm being itself supported by one of the primary arms, while the rod 7 connects the ends 62 and 43 of the primary arms remote from the plate 2.
  • the depth P of the ditch F being formed by the wheel 10 is varied by varying the length of the cylinder 12.
  • the depth P 'of the ditch F is relatively small because the primary arms formed respectively by the caisson 4 and by the elements 5 and 6 are lifted by the cylinder 12 and respectively rotate around the points A 1 and A 2 , as represented by the arrows F 1 and F 2 .
  • the primary arms turn respectively about the arms A 1 and A 2 as represented by the arrows F ' 1 and F' 2 at the figure 3 , so that the depth P '' of the pit F thus created is increased.
  • the jack 5 is set 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 according to 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 ⁇ can be increased up to a value ⁇ 'by contracting the cylinder 5.
  • a solid axle 14 is supported by two bearings 15 and 16 respectively provided in the caissons 4 and 9, while two pinions 17 and 18 are mounted at the ends respective axis 14 and fixed by two nuts 17a and 18a. These gears are intended to cooperate respectively with the chains 41 and 92.
  • the bearings 15 and 16 allow a rotational movement of the axis 14 relative to the tube 44, which allows a transmission of the movement of the chain 41 to the chain 92, in order to drive the wheel 10.
  • the tube 44 is connected to the main part of the box 4 by means of a weld bead 46.
  • a second bead 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 related to the sliding of the tube 44 inside the sleeve 91, this being possible thanks to the oblong character of the slots provided in the flange 48.
  • the bolts 19 could be replaced by a nut mounted on the end of the tube 44 inserted into the box 9, this end then being threaded.
  • the invention has the particular advantage that the structure formed of the elements 4 to 9 is compatible with the power transmission to the rolling wheel 10, by means of chains 41 and 92, while being adjustable.
