Definitions
- the present invention relates to a multi-share plow with adjustable working width, that is to say a multi-share plow provided with a device which makes it possible to modify at will the spacing between the plowing bodies.
- this type of plow includes a frame carrying the plow body, and the assembly is subject to the coupling head by means of deformable quadrilaterals which are most often similar to quasi-parallelograms to allow the various bodies parallel to each other and parallel to the longitudinal axis of traction.
- the present invention provides an improvement to this device for carrying out in a convenient manner, an automatic correction of the offset of the bodies with respect to the longitudinal axis of traction or with respect to the wheel of the tractor, each time the working width of the body.
- the frame of the plow on which the various bodies are articulated is carried by a drawbar which is articulated on the transverse beam of the coupling head, which drawbar constitutes a first side of the offset quadrilateral, which quadrilateral comprises a second side formed by said beam, a third side parallel to said drawbar and articulated on said beam also and a fourth side parallel to said beam interposed between the ends of the drawbar and said third side, which fourth side also constitutes one of the sides of the superelevation quadrilateral, and this fourth side consists of - an arm integral with the frame, which extends from the articulation of the latter on the drawbar, about 2/3 of the length of this fourth side of the quadrilateral and, - of a rocker-shaped lever, articulated between its two ends on the end of said arm, which rocker is articulated at one of its ends on the end of the third side of the offset parallelogram and, at its other end, on the offset jack, which jack is mounted directly on the drawbar
- the rocking lever comprises a branch which extends the arm of the frame to form the fourth side of the quadrilateral, the length of which is of the order of twice the length of the branch which extends from the side of the jack. offset.
- the third side of the offset quadrilateral consists of a hydraulic cylinder which makes it possible to carry out a recentering operation of the frame to facilitate the reversal of the plow if it is a reversible plow.
- FIG. 1 shows, in the form of a functional diagram, the plow according to the invention
- FIG. 2 shows the plow in a position of great working width
- the plow shown diagrammatically comprises a coupling head 1 associated with the lifting arms of a tractor not shown.
- This coupling head can be provided with a pin 2 on which is mounted a transverse beam 3.
- This beam 3 can be manipulated by conventional turning means, not shown, which allow the entire plow to pivot about axis 2, in the case of a conventional reversible plow.
- the frame 4 of the plow is connected to the beam 3 by means of a drawbar 5.
- This drawbar 5 is articulated on the beam 3 by means of a head axis T arranged near the turning axis 2.
- the frame 4 is articulated on the drawbar 5, around a frame axis B located at the other end of said drawbar.
- the drawbar 5 carries the frame 4 on which the different plowing bodies 6 are located.
- Each plowing body 6 is articulated on the frame 4 by means of a body axis C, C1.
- These axes C, C1 make it possible to modify the difference Z between two bodies, that is to say to modify the working width of the plow by adjusting the orientation angle V of the frame 4 relative to the longitudinal axis 7 of the plow.
- the bodies 6 remain parallel to each other by means of a rod 8 which interconnects the cranks 9 used to operate said bodies.
- these bodies are connected to the transverse beam 3 of the coupling head, by means of quadrilaterals: - a first quadrilateral defined by the axes A, B, T, E which corresponds to the offset quadrilateral, - a second quadrilateral defined by the axes A, B, C, D which corresponds to the superelevation quadrilateral or for adjusting the working width and, - defined parallelograms by the frame 4, the rod 8 and the cranks 9.
- the superelevation quadrilateral ABCD is materialized by a first side BC formed by a portion of the frame 4, by a second side CD which is constituted by the crank 92 secured to the age 13 of the body 62, which body is the second body of the frame 4, by a third side AD parallel to the side BC, which may be of adjustable length, consisting of a connecting rod 11; the fourth AB side of this superelevation quadrilateral is parallel to the CD side and is common with the first quadrilateral, i.e. the offset quadrilateral.
- This fourth side AB is substantially parallel to the transverse beam 3 which constitutes the second side TE of the offset quadrilateral.
- the other two sides of this offset quadrilateral consist for the first, of the drawbar 5 and for the second, on the AE side formed for example of a connecting rod 17 whose length corresponds to that of the drawbar 5, which connecting rod, as it will be shown below, can be adjustable, consisting of a turnbuckle or even a hydraulic cylinder which, in this case, makes it possible to carry out operations of refocusing of the entire plow, without modifying the setting of the width of work nor the adjustment of the offset.
- the drawbar 5 has over its length, a yoke 18 oriented towards the connecting rod 17 on which is articulated, around an axis 19, the barrel of a jack 21.
- This jack 21 constitutes the offset jack and it is anchored between the drawbar 5 and the fourth side AB common to the offset quadrilateral and the superelevation quadrilateral.
- This fourth side AB is particular in the sense that it takes the form of a broken line. It consists of an arm 22 secured to the frame 4 and a lever 30 in the form of a rocker. This lever 30 is articulated between its two ends on an axis 31 disposed at the end of the arm 22.
- the axis 31 is located, in the middle position, substantially on the line of the axes A, B, at a distance of B which is of the order of two thirds of the distance separating A and B.
- the offset cylinder 21 is articulated on the lever 30 around an axis 32.
- the branch 33 of the lever 30, arranged between the axis 31 and the axis A, has a length which is of the order of twice that of the branch 34 which is arranged between said axis 31 and the axis 32 which corresponds to the hinge pin of the jack 21 on said lever 30.
- the axes 31 and 32 are substantially aligned on the line joining the axes A and B.
- the frame 4 pivots around the axis B, to vary the angle V, by means of a jack 25 which is interposed between the fourth side AB common to the two offset and cant quadrilaterals, and a yoke 26 integral with said frame 4.
- This jack 25 can, as shown in dotted lines in the figure, be articulated at the level of axis A.
- the jack 21 is used to adjust the offset and in particular the offset related to the geometry of the plow and that of the tractor so as to establish a width X between the internal part of the wheel 20 of the tractor and the first body 61, which distance X corresponds substantially to the distance Z between two consecutive bodies 6.
- This adjustment of the offset is imposed by the track of the tractor, that is to say the distance Y which corresponds to half of said track.
- an action of the tilt cylinder 25 causes an automatic correction of the offset, that is to say of the distance X of the first body relative to the wheel 20 of the tractor, making this distance x correspond at the width z which is established between two consecutive plows.
- the axes A, 19 and 32 form a triangle whose side formed by the lever 30 has a fixed length.
- the side formed by the jack 21 has a length which is established as a function of the initial value of the offset. This length is adjusted by the operator according to the track of the tractor and the geometry of the plow.
- the side between the axes 19 and A has a length which varies under the effect of the jack 21 and especially under the effect of the jack 25 when the latter is maneuvered to adjust the working width Z. This variation in length is linked to the variation in the angle established between the jack 21 and the lever 30.
- an action of the jack 25 to reduce the working width in the direction of FIG. 3, that is to say to reduce the angle v between the frame 4 and the longitudinal axis 7, tends to deform the ABTE quadrilateral which induces a global displacement of the plow which tends to reduce the distance X between the first body 61 and the wheel 20 of the tractor, in the same way that the value z is reduced.
- an action on the jack 25 to increase the working width in the direction of FIG. 2, that is to say increase the angle V of the frame 4 relative to the axis 7, causes a deformation of the ABTE quadrilateral which displaces the plow and causes an increase in the distance X, that is to say a modification of the offset of the plow relative to the tractor wheel and to its longitudinal axis of traction 7, in the same way as the width z between two consecutive bodies.
- a jack 17 ′ between the axes A and E of the offset quadrilateral as shown in FIGS. 2 and 3, makes it possible to pivot the entire plow around the axis T.
- this jack 17 ′, or jack of recentering allows the center of gravity of the plow to be moved to approach the longitudinal axis 7, which makes it possible to facilitate turning maneuvers in the case of a reversible plow.
- This action of the recentering cylinder 17 ′ has no effect on the initial offset adjustment or on the adjustment of the working width. In fact, during this maneuver, the jack 21 and the jack 25 are kept stationary in order to avoid operating the axes of the different quadrilaterals.
- FIG. 2 schematically represents the position of the plow in a configuration with a large working width. Note in this configuration, that the triangle formed by the axes A, 19 and 32 is deformed with a strongly obtuse angle at the top at the level of the axis 32. The axis B of the frame has moved away from the longitudinal axis 7 of the plow. The jack 21 adjusted at the start, behaves like a simple rod of fixed length.
