Definitions
- the invention relates to a rotor of a machine intended for cut a ground and more particularly a rotor of a machine used for soil stabilization and recycling, as well as machine comprising such a rotor.
- Such machines are hereinafter referred to summarily as “stabilizer of ground ".
- the stabilization of a soil aims to transform, thanks to additives, imperfect soil into a resistant infrastructure.
- the upper layer of the soil to be stabilized is removed up to a predetermined depth, the materials composing it are introduced into a mixer into which are also introduced additives and, after mixing, redeposited on the original surface.
- the additives are scattered or spread over the surface of the soil to be stabilized or to recycle.
- the object of the invention is to propose a rotor of a soil stabilizer which allows improved mixing of the worked layer of a soil, whatever the nature of the soil to work and the fluidity of the material to be kneaded and its consistency, the improvement of the mixing should preferably consist of a a more uniform way of mixing both on the surface and depth.
- the rotor must be able to be mounted in place of a rotor existing without modification of the machine comprising it.
- a rotor of soil stabilizer comprising a cylindrical body having an axis and an outer surface, the body being provided on its surface of a plurality of tools for working the soil.
- the tools are arranged on curve segments of which at least two segments form opposite angles with a plane perpendicular to the axis of the rotor.
- the arrangement of the tools on the surface of the rotor body, especially when it is represented on the developed surface of the rotor body, is such that the tools are arranged in a pattern geometric composed by a plurality of curve segments, attached to each other or not. All the tools arranged on a curve segment constitutes a series of tools.
- a "curve segment” any line, straight line or curve, having an average orientation and allowing to define a mean angle between this curve segment and a plane perpendicular to the axis of the rotor.
- the longest sides of the developed surface of the rotor can serve indifferently, in the case of the present invention, for define the average orientation of the curve segments on which the tools are arranged forming a series of tools. If we consider the orientation of the curve segments with respect to any one planes perpendicular to the rotor axis, these segments of curve form, two by two, opposite angles with this plane.
- the object of the invention is also achieved by a machine comprising a rotor such as that described above.
- the rotor of the invention is distinguished from rotors previously used primarily by the disposal of tools, a replacement of an anterior rotor by a the invention does not necessarily result in a modification of the machine.
- Figure 1 shows a rotor of a stabilizer according to the invention in a perspective view.
- Figure 2 shows a tool holder with a tool intended to equip the rotor.
- Figure 3 shows the rotor of Figure 1 in an axial view.
- Figure 4 schematically represents the offset angular between two successive discs of the rotor of the invention.
- Figure 5 shows the developed surface of the rotor and a arrangement of tools.
- Figure 6 shows the rotor of Figure 1 in a side view relative to the axis of the rotor.
- a rotor of a soil stabilizer comprises, according to a mode preferred embodiment of the invention, a cylindrical body 1 having an axis A and an outer surface 2.
- the body 1 is cylindrical with revolution and can be made in one piece or made of several cylindrical elements successively attached to each other to the others and having the same axis A.
- the body 1 of the rotor is provided of a plurality of discs 3 arranged on the axis A of the rotor and at a axial distance from each other.
- Each of the discs 3 is made up of two, three or four tool supports 31 each of which carries, at its periphery 32, a tool 4 intended for working the soil.
- the number tool holders per disc depends on the structure or geometric pattern chosen according to which, or according to which, the tools must be arranged.
- each of the discs is consisting of a whole annular element, whatever the shape from its periphery or by two or more tool holders forming a ring assembly.
- the discs arranged on the axis A of the rotor are oriented angularly so that there is an angular offset ⁇ between the corresponding tools 4 and 4 'from neighboring discs.
- the curve segment has, on the developed surface of the rotor, the shape of a straight line. If, by against, these angles vary, we get an arched line or all other curved shape.
- a layout of tools 4 on segments of straight curves 5 and 6 corresponding to an embodiment preferred of the invention, is shown in Figure 5.
- the developed surface of the rotor shown in Figure 5 shows a preferred arrangement of the tools 4 on the surface 2 of the body 1 of the rotor.
- the tools 4 are arranged mainly in groups of six or seven tools with mainly two orientations which are distinguished from each other by the angle that the segments define with a plane P perpendicular to the axis A rotor.
- This plane P can be a median plane P o situated in the middle between the two ends of the body 1 or any other plane P 1 chosen arbitrarily over the axial length of the body 1 and materialized by any one of the discs 3.
- the plane P o we then relate to the plane P o .
- the curve segments 5 include segments 51 whose length corresponds to a location of six successive tools 4 and segments 52 whose length corresponds to the location of seven successive tools 4.
- the curve segments 51 and 52 are oriented so as to form with the plane P 0 an angle ⁇ 1 or an angle ⁇ 2 .
- the angles ⁇ 1 and ⁇ 2 can be, but are not necessarily, of the same magnitude.
- the curve segments 6 comprise segments 61 whose length corresponds to the location of six tools 4 and segments 62 whose length corresponds to the location of seven tools 4.
- the segments 61 and 62 are oriented so as to form with the plane P o respectively an angle ⁇ 1 or an angle ⁇ 2 .
- the angles ⁇ 1 and ⁇ 2 can be, but are not necessarily, of the same magnitude.
- Figure 5 also shows curve segments 63 and 64 which follow on the surface 2 of the body 1 and which correspond so, with regard to the total length of these two segments, to segment 61 whose total length corresponds to the location a suite of six tools 4.
- the orientations of the curve segments and, consequently, the measurements of the angles ⁇ 1 , ⁇ 2 , ⁇ 1 and ⁇ 2 are distinguished from one another as follows.
- the orientation of the segments 51, expressed by the angle ⁇ 1 is measured relative to the plane P 0 by looking, in FIG. 5, against the direction of rotation R.
- the orientation of the segments 52, characterized by the angle ⁇ 2 is measured relative to the plane P 0 by looking, in Figure 5, in the direction of rotation R.
- Each of the angles ⁇ 1 and ⁇ 2 is measured from the plane P 0 in the direction of the hands of a watch. The two angles open on different sides of the plane P 0 .
- the orientation of the segment 61 and of the segments 63 and 64 expressed by the angle ⁇ 1 is measured relative to and from the plane P 0 by looking against the direction of rotation R.
- the orientation segments 62, expressed by the angle ⁇ 2 is measured with respect to the plane P 0 by looking in the direction of rotation R.
- Each of the angles ⁇ 1 and ⁇ 2 is measured from the plane P 0 in the opposite direction of Clockwise. The two angles open on different sides of the plane P 0 .
- the curve segments arranged to the left of the plane P 0 referenced in order in the direction of rotation R by 63, 52, 61, 52 and 64, constitute a sequence of segments 7.
- the curve segments arranged on the right side with respect to the plane P 0 referenced in order in the direction of rotation R by 62, 51, 62 and 51, form a sequence of segments 8.
- the sequences of segments 7 and 8 occupy sections of the same axial length on the body of the rotor. In other words, each of the series of segments 7 and 8 defines the positions on which the tools 4 are disposed respectively in one or the other half of the two adjacent halves, in the axial direction of the rotor, of the body 1.
- Each of the structures 7 and 8 constitute a structure in W.
- the curve segments 7 and 8 do not follow each other directly, that is to say are not attached to each other, but constitute a kind of interrupted sequence.
- the interruption is done either by an axial offset of a tool towards an isolated position, as is the case of the tools referenced 41 and 42.
- Another possibility of interruption of the series of segments is constituted by an offset from the start of the next curve segment represented by tools 43 and 44, relative to the location of the last tool of the previous segment, represented by tools 45 and 46, so that tools 45 and 46 are not in line with the segments of curve to which the tools 43 and 44 belong.
- Each of the series of segments 7 and 8 is formed so that two successive segments of this series form opposite angles with the plane P 0 .
- this arrangement is represented by the opposite angles ⁇ 2 and ⁇ 1 for the series of segments 7 and by the angles ⁇ 1 and ⁇ 2 for the series of segments 8.
- segments of the curve correspondents of these two sequences of adjacent segments are angularly offset from each other as has been already mentioned with reference to Figures 1 and 3.
- the segments of curve corresponding to the embodiment shown in the Figure 5 are, in the direction of rotation R, the curve segments 52 and 62, segments 61 and 51, segments 52 and 62 and the segments 63, 64 and 51.
- the tools are arranged on two sequences of segment 7 and 8 respectively arranged on one or the other of two axially adjacent halves 11 and 12 of the body 1.
- This layout is shown schematically in Figure 6 in a side view with respect to the axis A of the rotor.

Abstract
Description
- Tous les segments de courbe situés du même côté d'un plan perpendiculaire à l'axe du rotor forment une ligne en zigzag. Cette disposition correspond à un mode de réalisation avantageux de l'invention selon lequel les outils sont montés sur le rotor de façon que les points d'attaque des outils, représentés par les segments de courbe, forment un motif ressemblant à une suite de zigzags, appelée ci-avant une ligne en zigzag. Plus particulièrement, les segments peuvent former une structure en forme de W.
- Selon un mode de réalisation préférée de l'invention, les outils
sont montés sur le rotor de façon que les segments de courbe
définissent au moins deux suites de segments disposées de part
et d'autre d'un plan perpendiculaire à l'axe du rotor et à une
distance axiale l'une de l'autre.
Souvent, la disposition des outils sur deux lignes en zigzag, l'une à côté de l'autre, est suffisante pour obtenir de bons résultats de malaxage avec le rotor de l'invention. Toutefois, une disposition des outils sur trois ou quatre lignes en zigzag, correspondant à une structure en trois ou quatre W, pour des rotors de grande longueur axiale, est également concevable. - Les suites de segments occupent avantageusement des parties de longueurs axiales égales du corps du rotor.
- Les segments de courbe correspondants de deux suites de
segments adjacentes sont angulairement décalés l'un par rapport
à l'autre.
Ce décalage dans le sens de rotation évite aussi bien une disposition parallèle des suites de segments qu'une disposition symétrique par rapport à un plan perpendiculaire à l'axe du rotor passant entre ces suites de segments et contribue ainsi à l'amélioration de la qualité du malaxage. - Le corps du rotor comprend une pluralité de disques disposés sur
l'axe du rotor et à une distance axiale l'un de l'autre. Chacun des
disques est pourvu à sa périphérie d'au moins un outil destiné à
travailler le sol.
Selon un mode de réalisation avantageux de l'invention, chacun de ces disques est constitué par quatre supports d'outil montés dans un même plan perpendiculaire à l'axe du rotor. Les disques sont orientés angulairement de façon que par le décalage angulaire entre deux disques voisins, les outils sont disposés sur les segments de courbe décrits plus haut.
