Definitions
- the present invention relates to a plow, preferably mounted or semi-mounted, multi-body, possibly reversible, with variable working width, for example from 12 "to 20" without change of body.
- Polysoc plows for which special settings allowing several working widths to be obtained without changing the bodies, are known.
- the principle is to modify the lateral spacing between all the bodies so that, starting from a coulter spacing of 16 inches ((about 40 centimeters) for example, one can with the same plow reduce the working width between body to 12 inches, (about 30 centimeters), or on the contrary increase it up to 20 inches (about 50 centimeters).
- This type of device applies in particular to plows consisting of a central carriage on which are joined a beam before body support and a rear beam body support.
- the body supports of the beam pivotally mounted on said beams by means of suitable axes are furthermore respectively joined together at a second pivot axis by a coupling member such as a connecting rod. , so as to form deformable parallelograms.
- the connecting rod is, for each beam, connected at one of its ends to a fixed point of the central carriage arranged between front beam and rear beam so that, during the lateral offset of the beams, the bodies are simultaneously displaced.
- An object of the present invention is therefore to propose a plow, possibly reversible, multi-body with variable working width in which all the devices for controlling the variation of the line width such as linkage, connecting rods, jacks or the like have been deleted.
- Another object of the present invention is to provide a plow, possibly reversible, multi-body whose design of the means of variation of the working width makes it possible to facilitate the crossing of obstacles by avoiding too frequent trips of the safety systems.
- the subject of the invention is a multi-body plow with a variable working width between a minimum width and a maximum width with the same bodies, of the type comprising at least one body support beam movable between two extreme positions so to be able to vary the angle formed by the beam and the horizontal line of traction, said bodies, consisting respectively of an age connected by means of a prop to the working parts, including at least one sep and a counter-sep , being pivotally mounted on said beams so as to be able to modify the angle between the bodies and the beam, characterized in that the bodies are mounted to pivot freely between two extreme positions of working width relative to the support beam by the intermediate a pivot axis, the leading edge of the working parts of the body being located substantially downstream of said pivot axis, each body being positioned relative to One pivot axis so that the cons-Sep body in the working position under normal conditions s' self aligned along a line parallel to the traction line during advance of the plow.
- Figure 1 shows a top view of a plow semi-mounted with adjustable working width
- FIG. 2 shows a top view of the semi-mounted plow of Figure 1 in a position in which the working width has been reduced;
- FIG. 3 represents a perspective view of a body formed by an assembly of age, prop, working parts
- Figure 4 shows a top view of the body of Figure 3.
- FIG. 5 represents a top view of the semi-mounted plow of FIG. 1 with a schematic representation of the angular displacements of the various constituent elements during the passage from one line width to another line width.
- the plow, object of the invention shown under general reference 1 can be a mounted, semi-mounted, towed, reversible or not.
- this plow comprises a central carriage 4 on which are mounted on the one hand a front beam 2, on the other hand a rear beam 3.
- the front beam 2 is connected, by means of a coupling 18 which will not be described in more detail below, on the tractor. It should be noted that the invention applies in the same way to a single-beam plow.
- the plow is of the reversible type.
- the reversibility device consists of two jacks arranged crossed in the vicinity of the coupling. This device is of a known type and will therefore not be described in detail below. However, the invention applies in the same way to a non-reversible plow.
- Each beam 2, 3 of the plow is also movable angularly with respect to the horizontal line T of traction.
- the displacements of the front 2 and rear 3 beams to modify the angle formed by these beams with the horizontal line T of traction can be controlled by means of control devices affecting a large number of shapes.
- the displacement of these front-rear beams can be made kinematically integral or on the contrary be made independent. Since such control devices are well known to those versed in this art, they will not be described in more detail below. The essential elements of such devices have been shown in particular in 19, 20, 21 in the figures.
- This plow further comprises plow bodies 5 mounted respectively to pivot on the front 2 or rear 3 beams so as to be able to modify the angle formed between the bodies 5 and the beam 2 or 3.
- plow body the assembly consisting of an age 6 connected, by means of a prop 7, to the working parts 8, these parts possibly including a sep 9 on which are fixed a ploughshare 11 and a moldboard 12 and a counter-sep 10.
- the counter-sep 10 is arranged to slide along the wall. This part 10, by leaning laterally on the wall, contributes to the balance of the plow.
- a razor disposed upstream of the assembly sep 9, counter-sep 10 described above. Only the skimmer holder 13 has been shown in the figures.
- Such bodies 5 are again perfectly known to those versed in this art.
- the bodies are mounted, between two extreme working width positions, with free pivoting relative to the beam (s) for supporting the bodies via a pivot axis. 14.
- the leading edge 17 of the working parts 8 of the bodies 5 is located substantially downstream of the pivot axis 14 and each body 5 is positioned relative to the pivot axis 14 so that the counter-sep 10 of the body 5 in the working position under normal conditions self-aligns along a line parallel to the line T of traction when advancing the plow.
- Such a freely pivotable mounting of these bodies 5 has two major advantages, namely on the one hand, the elimination of complex control devices such as linkages, jacks, or the like used until now, on the other hand, facilitated crossing obstacles, the bodies being able to be easily erased laterally during the passage of an obstacle due to their mode of connection to the support beam.
- the connections between body and beams can be diverse and varied.
- the bodies 5 are freely assembled to the beam 2 or 3 by means of brackets 15 carrying the pivot axis 14.
- This bracket 15 substantially affects the shape of an L of which one of the branches is coupled stationary on the beam while the other branch carries the pivot axis 14 connecting the body 5 to the beam 2 or 3.
- the working parts 8 of the body 5 self-oriented under the effect of traction are in turn coupled with age 6 by means of a prop 7, the assembly being arranged so that the result of the forces applying to the working parts 8 during work passes through age 6 and the pivot axis 14.
- the prop 7 connecting age 6 to the working parts 8 is in turn offset outside the axis of age as shown in Figure 1. It is generally the same for the support 13 razor holder which is offset laterally relative to the axis of age 8.
- the extreme positions of the pivoting bodies 5 are delimited by stops 16, preferably elastic, mounted between the bracket . 15 and age 6, respectively on the bracket 15 or on the age 6 to facilitate after crossing an obstacle the natural repositioning of the bodies 5 relative to the line T of traction.
- the positioning of the pivot axis 14 of articulation of the body 5 on the bracket 15 can be adjustable in position depending in particular on the nature of the soil to be plowed. It is noted that such a connection of the bodies to the beam makes it possible to reduce the stress on the non-stop safety devices or the like normally fitted to these bodies. Indeed, due to the possibility of lateral erasure of the body 5 when crossing an obstacle, there is less triggering of the safety devices and, consequently, reduced maintenance of the latter.
- leading edge of the working parts of the body is understood to mean the part of the working parts most upstream taken in the direction of advance of the plow.
