Description

Engin de labour multifonction utilisable pour effectuer les semailles La présente invention a pour objet un engin de labour multifonction qui peut être utilisé pour effectuer les semailles ou une simple préparation du sol tel qu'un hersage ou un rappui. . On sait que, le plus souvent, les semailles des graines telles que les céréales sont réalisées sur un terrain préalablement travaillé, à l'aide de semoirs qui déposent les graines sur une série de lignes parallèles, ou qui les distribuent en les répartissant sur le sol. Ces graines étant ensuite enfouies par un outil qui peut être de diverses natures. De telles semailles sont généralement connues sous les expressions "en lignes" et "à la volée" . The present invention relates to a multifunction plowing machine which can be used to carry out sowing or a simple preparation of the soil such as a harrowing or a press. . It is known that, most often, sowing of seeds such as cereals is carried out on previously worked land, using seeders which deposit the seeds on a series of parallel lines, or which distribute them by distributing them over the ground. These seeds are then buried by a tool which can be of various natures. Such sowing is generally known under the expressions "in lines" and "on the fly".
La présente invention a pour objet d'associer dans des conditions particulières un semoir et un engin de labour comportant au moins un train de disques en forme de calottes sphériques ou tronconiques, ledit train de disques pouvant être également utilisé comme engin de labour traditionnel lorsqu'il ne participe pas aux semailles ou simplement pour la préparation du sol pour un hersage ou un rappui.The object of the present invention is to combine, under special conditions, a seeder and a plowing machine comprising at least one train of discs in the form of spherical or frustoconical caps, said train of discs can also be used as a traditional plowing machine when it does not participate in sowing or simply for the preparation of the soil for harrowing or composting.
La présente invention a pour objet un engin de labour multifonction, caractérisé par le fait qu'il comporte au moins un train de disques sensiblement en forme de calottes sphériques ou tronconiques, la face convexe de chacun des disques est dirigée dans la direction du déplacement de l'engin, les disques agissant sur le sol par les extrémités inférieures de leurs faces convexes notamment, pour enfouir dans le sol les graines préalablement déposées.The present invention relates to a multifunction plowing machine, characterized in that it comprises at least one train of discs substantially in the form of spherical or frustoconical caps, the convex face of each of the discs is directed in the direction of movement of the machine, the discs acting on the ground by the lower ends of their convex faces in particular, to bury in the ground the seeds previously deposited.
Dans un mode de réalisation particulier de l'invention, l'engin comporte pour ameublir le sol en amont du train de disques qui enfouit les graines, un ou deux trains de disques parallèles qui travaillent à la manière conventionnelle en présentant leurs concavités dans la direction de l'avancement de l'engin.In a particular embodiment of the invention, the machine comprises, for loosening the soil upstream of the train of discs which buries the seeds, one or two trains of parallel discs which work in the conventional manner by presenting their concavities in the direction advancement of the craft.
Dans un autre mode réalisation, le sol peut être ameubli au devant du train de disques selon l'invention par d'autres moyens tels que des socs, des griffes ou autres scarificateurs.In another embodiment, the soil can be loosened in front of the train of discs according to the invention by other means such as plowshares, claws or other scarifiers.
Selon l'invention les graines peuvent être déposées sur le sol par tout dispositif de semailles approprié à la nature des graines.According to the invention, the seeds can be deposited on the ground by any sowing device suitable for the nature of the seeds.
C'est ainsi que pour du blé les graines peuvent être semées à la volée à l'avant ou à l'arrière du dispositif qui ameublit le soi. Grâce à l'invention, l'action de la partie inférieure convexe des disques a pour effet de repousser progressivement les graines sur le côté de leur convexité pour les placer sensiblement selon des lignes parallèles, tout en tassant légèrement le sol pour les enfouir. Selon un autre mode de réalisation de l'invention, on peut utiliser un semoir traditionnel en ligne qui dépose les graines entre les disques du train de disques selon l'invention et à l'avant de ceux-ci, ce qui assure une bonne mise en place des graines même à faible profondeur.This is how for wheat the seeds can be sown on the fly at the front or at the back of the device that loosens the self. Thanks to the invention, the action of the convex lower part of the discs has the effect of gradually repelling the seeds on the side of their convexity in order to place them substantially along parallel lines, while slightly compacting the soil to bury them. According to another embodiment of the invention, a traditional seed drill can be used in line which deposits the seeds between the discs of the train of discs according to the invention and at the front thereof, which ensures good placement seeds even in shallow depths.
On peut ainsi selon l'invention modifier la profondeur à laquelle les graines sont déposées dans le sol, en faisant varier la distance entre l'axe des disques et le point où les graines sont déposées sur le sol.It is thus possible according to the invention to modify the depth at which the seeds are deposited in the ground, by varying the distance between the axis of the discs and the point where the seeds are deposited on the ground.
Selon un mode de réalisation particulier de l'invention, le train de disques situé à l'arrière de l'engin peut être basculé autour d'un axe vertical, soit dans une position où les disques présentent leurs faces convexes dans la direction du déplacement de l'engin qui peut alors fonctionner notamment comme semoir conformément à l'invention ou pour effectuer un préparation du sol tel qu'un hersage ou un rappui, soit, dans une position où les disques présentent leur face concave en direction de l'avancement de l'engin, ce qui leur permet d'effectuer un labour traditionnel.According to a particular embodiment of the invention, the train of discs located at the rear of the machine can be tilted around a vertical axis, either in a position where the discs have their convex faces in the direction of movement of the machine which can then function in particular as a seed drill in accordance with the invention or for carrying out a soil preparation such as a harrowing or a press, either, in a position where the discs have their concave face in the direction of advancement of the machine, which allows them to perform traditional plowing.
Dans ce mode de réalisation particulier de l'invention, il est avantageux de disposer des paires de trains de disques identiques, symétriquement, de part et d'autre de l'axe central de l'engin de labour, ce qui permet de compenser les forces latérales qui auraient tendance à déporter latéralement l'engin s'il ne comportait que des trains de disques inclinés dans la même direction.In this particular embodiment of the invention, it is advantageous to have pairs of trains of identical discs, symmetrically, on either side of the central axis of the plowing machine, which makes it possible to compensate for the lateral forces which would tend to shift the machine laterally if it consisted only of disc trains inclined in the same direction.
Selon l'invention on peut aussi disposer si on le désire d'un engin comportant un ou plusieurs trains de disques parallèles qui peuvent dans un sens de marche être utilisés comme engin de labour et qui en sens inverse peuvent être utilisés comme semoir pour enfouir des graines déposées à la volée ou en lignes.According to the invention, it is also possible to have, if desired, a machine comprising one or more trains of parallel discs which can in one direction of travel be used as a plowing machine and which in the opposite direction can be used as a seed drill for burying seeds placed on the fly or in rows.
Conformément à l'invention, le contour des disques convexes peut être quelconque. C'est ainsi que l'on peut utiliser, conformément à l'invention, des disques lobés, c'est-à-dire des disques dont le périmètre est défini par une succession d'arcs de cercle convexes, des disques qui présentent sur leur périphérie une série d'entailles en arcs de cercle concaves, des disques convexes dont les bords présentent des nervures ou ondulations qui assurent un ameublissement du sol supplémentaire, ou encore des disques dont la périphérie est circulaire.According to the invention, the contour of the convex discs can be arbitrary. Thus it is possible to use, in accordance with the invention, lobed discs, that is to say discs whose perimeter is defined by a succession of arcs of convex circles, discs which have on their periphery a series of notches in concave arcs, convex discs whose edges have ribs or undulations which provide additional soil loosening, or even discs whose periphery is circular.
Les trains de disques convexes selon l'invention, peuvent être montés sur un axe commun en étant alors coaxiaux. Ils peuvent également être chacun supportés par un bras qui permet de régler à la fois l'inclinaison de chaque disque par rapport à la verticale et par rapport à la direction d'avancement. Tous les bras sont dans ce cas solidaires d'une même poutre pour constituer le train.The trains of convex discs according to the invention can be mounted on a common axis while being coaxial. They can also each be supported by an arm which makes it possible to adjust both the inclination of each disc with respect to the vertical and with respect to the direction of advance. All the arms are in this case integral with the same beam to constitute the train.
Dans le but de mieux faire comprendre l'invention on va en décrire maintenant à titre d'illustration et sans aucun caractère limitatif, plusieurs modes de réalisation donnés à titre d'exemples.In order to better understand the invention we will now describe by way of illustration and without any limiting character, several embodiments given by way of examples.
- la figure 1 est une vue schématique de dessus d'un engin selon l'invention,FIG. 1 is a schematic top view of a machine according to the invention,
- la figure 2 est un mode de réalisation particulier de l'engin selon l'invention dans lequel la terre est ameublie en amont du semoir par un train de disques travaillant de manière conventionnelle, - la figure 3 est un mode de réalisation de l'invention comportant des trains de disques disposés symétriquement de part et d'autre de l'axe de l'engin, les trains de disques arrières pouvant être basculés de manière à présenter dans la direction d'avancement, soit la face convexe des disques pour utiliser l'engin en semoir, soit leur face concave pour utiliser le train de disques de manière traditionnelle comme engin de labour,- Figure 2 is a particular embodiment of the machine according to the invention in which the soil is loosened upstream of the seed drill by a train of discs working in a conventional manner, - Figure 3 is an embodiment of the invention comprising disc trains arranged symmetrically on either side of the axis of the machine, the rear disc trains being able to be tilted so as to present in the direction of advance, ie the convex face of the discs to use the planter, or their concave side to use the train of discs in the traditional way as a plowing machine,
- les figures 4, 5 et 6 représentent des exemples de formes de disques qui peuvent être utilisées conformément à l'invention,FIGS. 4, 5 and 6 represent examples of shapes of discs which can be used in accordance with the invention,
- et la figure 7 représente un mode de réalisation selon lequel chaque disque selon l'invention est assujetti de manière réglable sur une poutre. On a représenté schématiquement sur la figure 1 un engin 1 qui permet d'ameublir le sol. Cet engin peut être constitué par exemple par des charrues traditionnelles, un ensemble de griffes, ou un ou plusieurs trains de disques de labour.- And Figure 7 shows an embodiment according to which each disc according to the invention is secured in an adjustable manner on a beam. Schematically shown in Figure 1 a machine 1 which loosens the soil. This machine can be constituted for example by traditional plows, a set of claws, or one or more trains of plowing discs.
Cet ameublissement du sol peut être réalisé soit antérieurement au passage de l'engin selon l'invention, soit avec un engin qui est physiquement relié à l'engin selon l'invention.This loosening of the soil can be carried out either before the passage of the device according to the invention, or with a device which is physically connected to the device according to the invention.
Dans ce dernier cas, un train de disques 2 est disposé à l'arrière de l'engin 1 qui se déplace dans le sens de la flèche F. Conformément à l'invention, le train de disques 2 comporte des disques 3 dont la face convexe est dirigée dans la direction F d'avancement de l'engin.In the latter case, a train of discs 2 is arranged at the rear of the machine 1 which moves in the direction of the arrow F. According to the invention, the train of discs 2 comprises discs 3, the convex face of which is directed in the direction F of advancement of the machine.
Conformément au mode de réalisation de la figure 1, on dispose à l'avant du train de disques 2 un semoir qui dépose les graines en 4 pour réaliser une semaille en lignes.According to the embodiment of Figure 1, there is at the front of the train of discs 2 a seed drill which deposits the seeds in 4 to make a sowing in rows.
Selon l'invention, les graines sont avantageusement déposées vers le milieu de la distance qui sépare les extrémités avant de deux disques voisins.According to the invention, the seeds are advantageously deposited around the middle of the distance which separates the front ends of two neighboring discs.
Dans une variante, les graines peuvent être semées à la volée devant le train de disques 2 selon l'invention. Selon l'invention, les disques convexes ne travaillent que sur une profondeur suffisante pour enfouir convenablement les graines.In a variant, the seeds can be sown on the fly in front of the train of discs 2 according to the invention. According to the invention, the convex discs work only over a sufficient depth to properly bury the seeds.
Grâce à la convexité des disques, les grames sont ainsi progressivement enfouies et tassées dans le sol en étant repoussées par la partie inférieure bombée des disques. II en résulte que même si les graines ont été semées à la volée, l'engin selon l'invention tend à les replacer selon des lignes grâce à l'action de la portée inférieure des disques convexes.Thanks to the convexity of the discs, the grames are thus gradually buried and compacted in the ground while being pushed back by the curved lower part of the discs. As a result, even if the seeds were sown on the fly, the machine according to the invention tends to replace them in lines thanks to the action of the lower bearing of the convex discs.
La figure 2 représente schématiquement un engin selon l'invention dans lequel on a placé pour ameublir le sol un train de disques conventionnel la en avant du train de disques 2 selon l'invention qui est associé à un semoir en lignes 4.FIG. 2 schematically represents a machine according to the invention in which a conventional disc train 1a in front of the disc train 2 according to the invention which is associated with a seed drill 4 has been placed to loosen the soil.
On a représenté sur la figure 3 comment il est avantageux de réaliser un engin selon l'invention, en disposant à l'avant de celui-ci, symétriquement par rapport à l'axe de l'engin, deux trains de disques la et lb qui présentent la concavité des disques en direction de l'avancement, et à l'arriére deux trains de disques 2a et 2b qui sont susceptibles de pivoter autour d'un axe vertical entre une première position représentée en trait plein dans lesquels les trains de disques 2a et 2b présentent la concavité des disques dans le sens de l'avancement de l'engin, qui a pour effet de jouer le rôle d'un engin de labour habituel, et une deuxième position représentée sur la figure 3 en trait interrompu, dans laquelle les trains de disques 2a et 2b présentent leur convexité en direction de l'avancement de l'engin, ce qui permet de les associer à un semoir en ligne 4 qui est représenté en ligne interrompue sur la figure 3 mais qui pourrait être un semoir à la volée.FIG. 3 shows how it is advantageous to produce a machine according to the invention, by arranging at the front thereof, symmetrically with respect to the axis of the machine, two sets of discs 1a and 1b which have the concavity of the discs in the direction of advancement, and at the rear two disc trains 2a and 2b which are capable of pivoting about a vertical axis between a first position shown in solid lines in which the disc trains 2a and 2b show the concavity of the discs in the direction of advancement of the machine, which has the effect of playing the role of a usual plowing machine, and a second position shown in FIG. 3 in broken lines, in which disc trains 2a and 2b have their convexity in the direction of advancement of the machine, which allows them to be associated with a seed drill 4 which is shown in broken line in Figure 3 but which could be a seed drill on the fly.
Cette disposition symétrique de l'engin de la figure 3 permet d'équilibrer les forces latérales exercées par les trains de disques lorsque ces derniers ont leurs axes parallèles.This symmetrical arrangement of the machine of FIG. 3 makes it possible to balance the lateral forces exerted by disc trains when the latter have their axes parallel.
Par contre, dans le mode de réalisation de la figure 2, le fait que le train de disques de labour la et le train de disques 2 qui participent aux semailles s'équilibrent sensiblement compte tenu du fait que leurs inclinaisons sont opposées. Différentes formes de disques peuvent être utilisées.On the other hand, in the embodiment of FIG. 2, the fact that the train of plowing discs la and the train of discs 2 which participate in sowing are balanced substantially taking into account the fact that their inclinations are opposite. Different forms of discs can be used.
La figure 4 représente un disque multilobé connu qui, en plus de sa forme de calotte sphérique présente sur sa périphérie une série de lobes 5.FIG. 4 represents a known multilobed disc which, in addition to its shape of a spherical cap, presents on its periphery a series of lobes 5.
La figure 5 représente un disque connu dont les bords sont découpés par des évidements 6 de forme arrondie. Enfin, la figure 6 représente un disque connu dont la périphérie est circulaire, ce disque ayant essentiellement une forme de calotte sphérique.FIG. 5 represents a known disc whose edges are cut by recesses 6 of rounded shape. Finally, FIG. 6 represents a known disc whose periphery is circular, this disc essentially having the shape of a spherical cap.
On a représenté sur la figure 7 un mode de réalisation dans lequel chaque disque 9 est fixé sur une poutre 7 à l'aide d'un bras articulé 8 qui peut être maintenu dans diverses positions angulaires autour des axes 10 et 11.FIG. 7 shows an embodiment in which each disc 9 is fixed to a beam 7 using an articulated arm 8 which can be held in various angular positions around the axes 10 and 11.
On peut ainsi orienter les disques dans une position optimale en fonction des semailles à effectuer.It is thus possible to orient the discs in an optimal position according to the sowing to be carried out.
Il n'est pas nécessaire selon l'invention que les disques aient une forme de calotte sphérique au sens géométrique du mot et si on le juge utile on peut utiliser par exemple des disques de forme conique aplatie pu des disques en forme d'assiette.It is not necessary according to the invention that the discs have a shape of a spherical cap in the geometric sense of the word and if it is deemed useful one can use for example discs of flat conical shape or discs in the form of a plate.
De même les disques peuvent être munis sur leurs périphéries de nervures ou d'ondulations qui assurent un ameublissement du sol supplémentaire.Similarly, the discs can be provided on their peripheries with ribs or corrugations which provide additional soil loosening.
On peut selon l'invention utiliser divers types de disques tels que des disques gaufrés et des disques fléaux. II est clair que les modes de réalisation qui ont été décrits ci-dessus ne présentent aucun caractère limitatif et qu'ils pourront recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention. It is possible according to the invention to use various types of discs such as embossed discs and flail discs. It is clear that the embodiments which have been described above have no limiting character and that they can receive any desirable modifications without departing from the scope of the invention.
