Definitions
- the present invention relates to a device for digging trenches.
- devices for digging trenches of the type comprising at least one cutting wheel which can rotate around an axis and provided with a wheel chassis, which is connected at the rear of a vehicle by means of a mobile carriage enabling the cutting wheel to be lowered or raised, said wheel, in the digging position, lying behind said vehicle and being pulled by it by turning around its axis which is transverse to the direction of movement of said vehicle.
- the object of the present invention is to avoid these drawbacks, and relates to a device for digging trenches allowing, whatever the terrain and whatever the trajectory of the vehicle, to dig a regular trench which is perfectly suited for laying cables, or the like.
- said slicer wheel can pivot by a maximum pivot angle comprised, each time, between approximately 10 ° and approximately 15 °, on either side of an intermediate position of the wheel.
- the device comprises means for moving said wheel chassis is connected to said carriage by an intermediate piece articulated, on the one hand, to said wheel chassis around said first pivot axis and fixed, on the other hand, said carriage being able to pivot, in a limited manner with respect to said carriage around said second pivot axis.
- the first pivot means comprise a jack, or the like, connected, on the one hand, to said wheel chassis and, on the other hand, to said intermediate piece
- said second pivot means can comprise a jack, or similar, connected, on the one hand, to said intermediate piece and, on the other hand, to said carriage.
- the device comprises means for moving said carriage transversely to the direction of movement of said vehicle.
- said means for transversely moving the carriage comprise a jack, or the like, connected, on the one hand, to said carriage and, on the other hand, to said vehicle.
- said wheel chassis has a general shape of L, a first branch of which is connected to said carriage via said first pivot axis and the second branch of which carries the wheel, said first and second branches being articulated to each other by means of a third pivot axis parallel to the axis of rotation of the wheel, third pivot means, consisting of at least one jack, or the like, capable of connecting the far ends of said first and second branches.
- the wheel is provided, in the vicinity of its entire periphery, with angularly spaced holes.
- the device 1 for digging a trench 2 comprises a cutting wheel 3 which can rotate around an axis 4 and which is provided, at its periphery, with a plurality of angularly spaced cutting tools 5.
- the slicer wheel 3 is mounted under a wheel chassis 6 and can be mounted, for example, on a plate 7 for fixing the wheel 3 to the chassis 6.
- the wheel chassis 6 is connected to a vehicle 8 by means of a movable carriage 9 making it possible to lower or raise the slicer wheel 3, the raised position of the wheel being shown in broken lines in FIG. 1.
- the device 1 comprises first means, constituted, in this example of realizing sation, by a jack 10, capable of pivoting, in a limited way, the cutting wheel 3 around a first pivot axis 11 orthogonal to the plane defined by the direction of movement F of the vehicle 8 and the axis of rotation 4 of the slicer wheel 3, and second means, constituted, in this embodiment, by a jack 12, capable of pivoting, in a limited manner, the slicer wheel 3 around a second pivot axis 13 orthogonal to the plane defined by the first pivot axis 11 and an axis parallel to the axis of rotation 4 of the wheel 3.
- the wheel chassis 6 is connected to the carriage 9 by an articulated intermediate piece 14, of on the one hand, to the wheel chassis 6 around the first pivot axis 11 and fixed, on the other hand, to the carriage 9 while being able to pivot, in a limited manner, relative to the carriage 9 around the second pivot axis 13.
- the fixing of the intermediate part 14 of the carriage 9 will be explained below, in more detail, with reference to FIGS. 4 and 5.
- the jack 10 is connected, on the one hand, to the wheel chassis 6 by a yoke 15 and, on the other hand, to the intermediate part 14 by a yoke 16.
- the jack 12 is connected, on the one hand to the intermediate piece 14 by a yoke 17 (FIG. 4) and, on the other hand, to the carriage 9 by a yoke 18 fixed to the carriage by a fixing lug 19 ( Figures 5 and 6).
- carriage 9 is guided in translation (up and down) on rails 20 of cross section at C and using rollers 21.
- the front face 22 of the carriage 9 is provided with five pins 23 (FIG. 5), and the corresponding plate 24 of the intermediate piece 14 is provided with a circular central hole 40 traversed in the mounted position by the central pin 23 then playing the role of the second pivot axis 13, and of four arcuate slots 25 (crossed by the other four pins 23) allowing the limited pivoting of the intermediate piece 14 relative to the carriage 9 around the axis 13.
- the central hole 40 and the lights 25 are shown in dashed lines in FIG. 5.
- the assembly of the carriage 9 and of the intermediate piece 14 is held by nuts 26 each cooperating with the pins 23.
- the intermediate part 14, and therefore the wheel 3 can pivot around the axis 13 relative to the carriage 9 by a maximum angle A equal, for example, to 14 ° , on either side of an intermediate position (figure 5.).
- the wheel 3 can pivot around the axis 11 by a maximum angle B equal, for example, to 12 ° , on either side of an intermediate position ( Figure 4).
- the device 1 comprises a jack 27 (FIG. 2) for moving the carriage 9, with its support bracket 28, transversely to the direction of movement F of the vehicle 8.
- the jack 27 is connected, on the one hand, to the vehicle 8 by a yoke 29 and, on the other hand, to the bracket 28 by a yoke 30.
- the assembly of the carriage 9 and the bracket 28 can thus slide transversely along guide rails 31 of cross section in C.
- the wheel chassis 6 has a general shape of L, a first branch 32 of which is connected to the carriage 9 via the first pivot axis 11 and the intermediate part 14, and the second branch of which 33 carries the wheel 3.
- the first 32 and second 33 branches are articulated to each other by means of a third pivot axis 34 parallel to the axis of rotation of the wheel 3.
- Two jacks 35 arranged on either side of the wheel 3, connect the distant ends of said first 32 and second 33 branches by being mounted on yokes 36 and 37, respectively, thus being able to raise the wheel 3 by rotating it around the axis 34.
- the wheel 3 is provided, in the vicinity of its entire periphery, with holes 38 angularly spaced.
- the device of the invention thus makes it possible to orient the trench wheel in space so as to always obtain a regular trench perfectly suited for laying cables, or the like.
