Description

DISPOSITIF DE TRAVAIL DU SOL MULTIFONCTIONS MULTIFUNCTIONAL SOIL WORKING DEVICE
La présente invention concerne les dispositifs de travail du sol qui permettent de remplir plusieurs fonctions afin de diminuer le nombre de passages dans les exploitations, donc le temps passé avec tous les avantages qui en découlent. On connaît des dispositifs qui permettent de travailler la terre, de déposer des graines en surface et de compacter la terre.The present invention relates to soil-working devices which make it possible to fulfill several functions in order to reduce the number of passages in the holdings, therefore the time spent with all the advantages which result therefrom. Devices are known which make it possible to work the soil, to deposit seeds on the surface and to compact the soil.
C'est ainsi que la demande de brevet EP N°764 397 décrit un semoir destiné à répartir des semences dans un sol préparé ou non. Un tel semoir comprend un châssis de base, une pluralité d'unités formant outils de travail du sol avec des modules composés chacun d'un système de coupe et de stabilisation avec deux roues jumelées et un soc.Thus, patent application EP No. 764,397 describes a seed drill intended for distributing seeds in a soil, whether prepared or not. Such a seed drill comprises a base frame, a plurality of units forming soil working tools with modules each composed of a cutting and stabilization system with two twin wheels and a ploughshare.
Chaque module est monté sur le châssis avec un parallélogramme déf ormable. Un système de distribution de semence permet de déposer des graines derrière le soc, sur le sol après que celui-ci a été travaillé par un disque. V invention porte sur des moyens de commande des mouvements du parallélogramme déformable avec des pistons et cylindres auto-compensés, sans admission de fluide complémentaire, en sorte de régler l'assise de l'engin.Each module is mounted on the chassis with a definable parallelogram. A seed distribution system allows seeds to be deposited behind the ploughshare, on the ground after it has been worked by a disc. The invention relates to means for controlling the movements of the deformable parallelogram with self-compensating pistons and cylinders, without admission of additional fluid, so as to adjust the seat of the machine.
Un tel semoir pose le même problème que beaucoup d'engins agricoles prévus pour semer, il ne peut travailler dans des conditions humides pour des raisons de bourrage.Such a seeder poses the same problem as many agricultural machines intended for sowing, it cannot work in wet conditions for reasons of stuffing.
En effet, dans les terrains à céréales par exemple, les sillons sont serrés avec un espace inter-rangs de 15 à 20 cm pour donner un ordre de grandeur. Or le but pour un exploitant est de pouvoir semer directement sur un terrain, y compris en présence de chaume résiduel, que le terrain soit sec ou qu'il soit très gras. Aussi, dans le cas où il y a du chaume, on comprend que lors du travail nécessaire de la terre, si les outils sont disposés côte à cote, compte tenu des espaces inter-rangs très limités, il se produit des bourrages entre les socs. Dans le cas de l'art antérieur précité, les modules de travail sont décalés dans le sens longitudinal mais chaque module comprend tous les outils regroupés en un, à savoir un disque ouvreur interposé entre deux roues avec les bourrages inhérents à cet agencement, puis, immédiatement en arrière on trouve le soc. Compte tenu de l'encombrement latéral de chaque module, il est impossible de semer avec des rangs peu espacés.Indeed, in grain fields for example, the furrows are tight with an inter-row space of 15 to 20 cm to give an order of magnitude. However, the goal for an operator is to be able to sow directly on land, including in the presence of residual stubble, whether the land is dry or very oily. Also, in the case of thatch, it is understood that during the necessary work of the soil, if the tools are placed side by side, taking into account the very limited inter-row spaces, jams occur between the coulters . In the case of the aforementioned prior art, the working modules are offset in the longitudinal direction but each module includes all the tools grouped into one, namely an opening disc interposed between two wheels with the jams inherent in this arrangement, then, immediately behind we find the ploughshare. Given the lateral dimensions of each module, it is impossible to sow with rows that are not closely spaced.
De même, l'encombrement des parallélogrammes déformables ne permet pas non plus de rapprocher les modules d'un même train, ce qui conduit à des engins de grandes dimensions.Likewise, the size of the deformable parallelograms also does not allow the modules to be brought closer to the same train, which leads to large machines.
Les dents de déchaumage ne peuvent être utilisées dans les conditions humides car elles soulèvent de grandes quantités de terre et provoquent des colmatages sans pour autant préparer le sol pour l'ensemencement. La présente invention a pour objet de proposer un dispositif de travail d'un sol et éventuellement d'ensemencement de ce sol, sans préparation préalable et autorisant des actions en toutes conditions y compris des conditions humides et avec du chaume.Dethatching tines cannot be used in wet conditions as they lift large amounts of soil and cause clogging without preparing the soil for sowing. The object of the present invention is to provide a device for working a soil and possibly for seeding this soil, without prior preparation and authorizing actions under all conditions including wet conditions and with thatch.
La présente invention propose un dispositif simple donc fiable et robuste dont la répartition des outils est avantageusement prévue pour permettre un travail tous temps.The present invention provides a simple device therefore reliable and robust, the distribution of tools is advantageously provided to allow work all weather.
La présente invention est maintenant décrite en détail selon un mode de réalisation préférentiel, en regard des dessins sur lesquels les différentes figures représentent : - figure 1, une vue de dessus du dispositif sophistiqué selon la présente invention, avec le dispositif de distribution de semence retiré,The present invention is now described in detail according to a preferred embodiment, with reference to the drawings in which the different figures represent: FIG. 1, a top view of the sophisticated device according to the present invention, with the seed distribution device removed,
- figure 2, une vue en élévation latérale de ce même dispositif supportant le dispositif de semence, et - figure 3, une vue de dessus de ce même dispositif dans une version différente de l'agencement de son bâti.- Figure 2, a side elevational view of the same device supporting the seed device, and - Figure 3, a top view of the same device in a different version of the arrangement of its frame.
Sur la figure 1, on a représenté un bâti 10, muni d'un timon 12 avec un crochetIn Figure 1, there is shown a frame 10, provided with a drawbar 12 with a hook
14 ou des moyens de liaison sur l'attelage trois points d'un tracteur, non figuré. Ce bâti est porté par un train 16 de roues 18, en l'occurrence deux roues.14 or connecting means on the three-point hitch of a tractor, not shown. This frame is carried by a train 16 of wheels 18, in this case two wheels.
Ces roues sont libres en rotation sur l'arbre 20 qui les porte.These wheels are free to rotate on the shaft 20 which carries them.
Dans le mode de réalisation perfectionné de cette figure 1, le bâti 10 comprend deux parties, l'une amont 22 et l'autre aval 24, par rapport au sens de déplacement de l'ensemble. Chacune de ces parties est elle-même réalisée en deux éléments 22-1, 22-2 ; 24-1, 24-2 articulés par rapport au bâti, suivant un axe parallèle au sens d'avancement.In the improved embodiment of this FIG. 1, the frame 10 comprises two parts, one upstream 22 and the other downstream 24, relative to the direction of movement of the assembly. Each of these parts is itself made up of two elements 22-1, 22-2; 24-1, 24-2 articulated with respect to the frame, along an axis parallel to the direction of advance.
En outre, un tel agencement permet au châssis de mieux épouser les formes du terrain et, avantage non négligeable, ces éléments articulés peuvent être relevés à la verticale en sorte de limiter la largeur de l'engin au gabarit routier. Il suffit de prévoir des moyens de relevage avec des vérins, non représentés pour la clarté du dessin, de tels moyens étant à la portée de l'homme de l'art et bien connus dans le milieu agricole.In addition, such an arrangement allows the chassis to better match the shapes of the terrain and, significant advantage, these articulated elements can be raised vertically so as to limit the width of the machine to the road gauge. It suffices to provide lifting means with jacks, not shown for clarity of the drawing, such means being within the reach of ordinary skill in the art and well known in the agricultural community.
La description qui suit, sera faite en considérant simplement la partie amontThe following description will be made by simply considering the upstream part
22 comme une entité et la partie aval 24 comme une autre entité, sachant qu'elles sont en réalité séparées, y compris les rouleaux, pour permettre une bonne articulation comme indiqué précédemment, pour autoriser le relevage et présenter des dimensions extérieures au gabarit routier.22 as an entity and the downstream part 24 as another entity, knowing that they are in reality separated, including the rollers, to allow good articulation as indicated above, to allow the lifting and have dimensions outside the road gauge.
La partie amont comprend un bâti 26 secondaire, solidaire du bâti principal. Ce bâti 26 secondaire amont comprend une rangée 27-1 unique de moyens 28-1 de coupe, dans le cas représenté, des disques 30-1 montés libres en rotation sur des supports 32-1 indépendants. Ces disques sont espacés latéralement d'une distance X égale à deux fois la distance S d'écart entre deux sillons 34 adjacents.The upstream part comprises a secondary frame 26, integral with the main frame. This upstream secondary frame 26 comprises a single row 27-1 of means 28-1 for cutting, in the case shown, discs 30-1 mounted free in rotation on independent supports 32-1. These discs are spaced laterally by a distance X equal to twice the distance S of difference between two adjacent grooves 34.
De plus, on note que ces disques sont choisis pour agir avec une grande profondeur de travail et pénètrent dans le sol de façon importante. Dans le mode de réalisation préférentiel de l'invention, derrière chacun des disques, il est disposé un soc 36-1. Ces socs 36-1 sont répartis sur deux rangées 37-1 et 39-1 en aval de la rangée 27-1 de moyens 28-1 de coupe. Ces rangées sont décalées dans le sens longitudinal et dans le sens transversal, en quinconce.In addition, we note that these discs are chosen to act with a great depth of work and penetrate into the ground significantly. In the preferred embodiment of the invention, behind each of the discs, there is a ploughshare 36-1. These plowshares 36-1 are distributed over two rows 37-1 and 39-1 downstream of the row 27-1 of cutting means 28-1. These rows are staggered longitudinally and transversely, staggered.
En effet, les socs sont écartés d'une distance 2X les uns des autres sur chaque rangée et les socs de l'une des deux rangées sont décalés de X par rapport aux socs de l'autre rangée en sorte d'avoir un soc aligné avec chaque disque. La profondeur de travail du soc est de préférence inférieure à celle de la profondeur de pénétration du disque.Indeed, the coulters are separated by a distance 2X from each other on each row and the coulters of one of the two rows are offset by X relative to the coulters of the other row so as to have a plowshare aligned with each disc. The working depth of the coulter is preferably less than that of the penetration depth of the disc.
On constate dès lors une distance importante entre tous les différents éléments tout en gardant un pas de travail sur la partie amont de X. Ainsi, la partie amont réalise la moitié des sillons qui sont espacés d'une distance X. Dans le cas où le dispositif est prévu non seulement pour déchaumer mais aussi pour semer immédiatement après le travail du sol, chaque soc est équipé d'une alimentation 40 en semence et il convient de se reporter à la figure 2. Chaque alimentation est reliée à des moyens 42 distributeurs avec une trémie 44 d'alimentation et des flexibles 46 de transfert.There is therefore a significant distance between all the different elements while keeping a working step on the upstream part of X. Thus, the upstream part performs half of the grooves which are spaced by a distance X. In the case where the device is provided not only for stubble plowing but also for sowing immediately after working the soil, each ploughshare is equipped with a seed supply 40 and reference should be made to FIG. 2. Each supply is connected to means 42 distributors with a feed hopper 44 and flexible hoses 46.
Les graines de semence sont déposées immédiatement derrière le soc dans le sillon formé et ouvert par le disque. A cet effet, des cannes de distribution, non représentées mais bien connues dans le domaine agricole permettent la dépose derrière le soc des graines sans risque de détérioration au cours de la progression du dispositif.The seeds are deposited immediately behind the share in the groove formed and opened by the disc. To this end, distribution rods, not shown but well known in the agricultural field allow the deposits seeds behind the ploughshare without risk of deterioration during the progression of the device.
La partie 24 aval est identique à la partie 22 amont et comprend une rangée 27-2 de moyens 28-2 de coupe, à savoir des disques 30-2 montés libres en rotation sur des supports 32-2 indépendants également. Ces disques sont espacés latéralement d'une distance X égale à deux fois la distance S d'écart entre deux sillons 34 adjacents, comme pour la partie amont. Derrière chacun des disques, on retrouve un soc 36-2. Ces socs 36-2 sont répartis sur deux rangées 37-2 et 39-2, en aval de la rangée 27-2 de moyens 28-2 de coupe.The downstream part 24 is identical to the upstream part 22 and comprises a row 27-2 of cutting means 28-2, namely discs 30-2 mounted free in rotation on independent supports 32-2 also. These discs are spaced laterally by a distance X equal to twice the distance S of difference between two adjacent grooves 34, as for the upstream part. Behind each of the discs, there is a coulter 36-2. These coulters 36-2 are distributed over two rows 37-2 and 39-2, downstream of the row 27-2 of cutting means 28-2.
Les socs sont écartés d'une distance 2X les uns des autres sur chaque rangée et les socs de l'une des deux rangées sont décalés de X par rapport aux socs de l'autre rangée en sorte d'avoir un soc aligné avec chaque disque. En plus, l'ensemble des disques de cette partie aval et donc des socs qui sont alignés, est décalé par rapport à celui de la partie amont d'une valeur de X/2. Ainsi, suivant le sens de déplacement, l'ensemble des disques et socs des deux parties permet de générer un ensemble de sillons séparés de X/2, donc de la distance S recherchée, à savoir l'espace inter-rangs. On constate que les sillons peuvent être très rapprochés sans que les éléments qui permettent de les réaliser soient proches les uns des autres notamment les socs.The coulters are spaced 2X apart from each other in each row and the coulters in one of the two rows are offset by X relative to the coulters in the other row so as to have a coulter aligned with each disc . In addition, all of the disks in this downstream part and therefore the coulters which are aligned, are offset from that of the upstream part by a value of X / 2. Thus, according to the direction of movement, the set of disks and plowshares of the two parts makes it possible to generate a set of grooves separated by X / 2, therefore by the distance S sought, namely the inter-row space. It is noted that the grooves can be very close together without the elements which allow them to be produced being close to each other, in particular the coulters.
En effet, ceux-ci sont régulièrement répartis sur deux rangées écartées d'une distance susceptible d'être au moins de 2X et écartés de 2X sur une même rangée, si bien que quasiment tous les risques de bourrage sont supprimés.Indeed, these are regularly distributed over two rows spaced apart by a distance capable of being at least 2X and spaced 2X apart in the same row, so that almost all the risks of jamming are eliminated.
Par contre l'agencement des moyens de coupe, en l'occurrence les disques, permet d'attaquer de front tout obstacle et tranche les agglomérats de terre et de chaume, les racines, les éventuelles branches et autres débris de culture susceptibles de provoquer un bourrage.On the other hand, the arrangement of the cutting means, in this case the discs, makes it possible to attack any obstacle head-on and cuts the agglomerates of soil and thatch, roots, any branches and other crop debris that may cause a blockage.
Les flexibles 46 se prolongent en arrière des socs pour venir délivrer en aval de ces socs, au fond du sillon réalisé, les semences distribuées, ceci de façon connue. La densité de distribution des graines est proportionnelle à l'avancement en sorte de respecter le taux linéaire recherché de semences. De façon avantageuse, les socs peuvent être du type à montage amovible, par encliquetage. On peut utiliser les montages commercialisés sous la dénomination "Bourgault". Dans le cas d'une telle liaison par encliquetage, les montages et démontages sont plus beaucoup plus rapides.The hoses 46 extend behind the plowshares to come deliver downstream of these plowshares, at the bottom of the groove made, the seeds distributed, this in known manner. The seed distribution density is proportional to the progress so as to respect the desired linear seed rate. Advantageously, the coulters can be of the removable mounting type, by snap-fastening. The assemblies sold under the name "Bourgault" can be used. In the case of such a snap connection, the assemblies and disassemblies are much faster.
Bien entendu, un tel agencement à montage amovible est d'un coût plus élevé mais il permet de travailler en terrain normal, à sec avec un soc ayant une dent de grande largeur qui assure ainsi le complément de déchaumage en plus du semi, mais aussi de travailler en terrain humide avec des dents ayant une voie plus étroite.Of course, such an arrangement with removable mounting is of a higher cost but it makes it possible to work in normal, dry ground with a ploughshare having a very wide tooth which thus ensures the additional dethatching in addition to the semi, but also to work in wet ground with teeth having a narrower path.
En complément, il est possible de disposer en aval des deux parties, une herse 48 de recouvrement, avec des lames plates à effort de rappel élastique qui viennent assurer la fermeture de chacun des sillons et le recouvrement des graines. Chacune des lames plates se trouve alignée avec un des disques de la partie amont et/ou de la partie aval.In addition, it is possible to have downstream of the two parts, a harrow 48 of recovery, with flat blades with elastic return force which come to ensure the closing of each of the furrows and the recovery of the seeds. Each of the flat blades is aligned with one of the disks of the upstream part and / or of the downstream part.
Il est aussi possible d'adjoindre à chaque soc une spatule 50 pour plaquer la semence sur la terre, au fond du sillon.It is also possible to add a spatula 50 to each share to place the seed on the ground, at the bottom of the furrow.
Enfin, un rouleau 52 niveleur est tracté à l'arrière de l'équipement. Un tel rouleau 52 peut être un rouleau plein ou un rouleau à barres, suivant l'état du terrain.Finally, a leveler roller 52 is towed behind the equipment. Such a roller 52 can be a solid roller or a bar roller, depending on the state of the ground.
De plus, un deuxième rouleau 54 est prévu pour être monté à l'avant du dispositif, ce qui permet de stabiliser l'ensemble par rapport au terrain. Un tel rouleau 54 assure la fonction de jauge et d'équilibrage de l'engin et est équipé préférentiel lement de fers plats pour briser les pailles en amont du travail des disques et des socs. Un tel rouleau comprend des fers plats qui sont orientés radialement et munis d'un bord tranchant. On peut se reporter à la demande de brevet français N°0205246 au nom du même demandeur pour mieux appréhender un tel rouleau.In addition, a second roller 54 is provided to be mounted at the front of the device, which makes it possible to stabilize the assembly with respect to the terrain. Such a roller 54 performs the function of gauge and balancing of the machine and is preferably equipped with flat irons to break up the straws upstream of working the discs and coulters. Such a roller comprises flat irons which are oriented radially and provided with a cutting edge. We can refer to French patent application No. 0205246 in the name of the same applicant to better understand such a roller.
En ce qui concerne le positionnement des outils, il est prévu des moyens 56, par exemple des vérins hydrauliques qui agissent sur la position du train de roues par rapport au châssis, permettant ainsi de régler la jauge. Les rouleaux 52 et 54 sont eux-mêmes ajustés de façon préalable à l'aide de broches, ceci de façon connue.With regard to the positioning of the tools, means 56 are provided, for example hydraulic jacks which act on the position of the wheel set relative to the chassis, thus making it possible to adjust the gauge. The rollers 52 and 54 are themselves adjusted beforehand using pins, this in known manner.
On peut prévoir des roues latérales de jauge mais cela ne paraît pas idéal. Sur la figure 3, on a représenté un agencement avec un bâti différent qui est constitué des mêmes outils de travail. La différence se situe au niveau de la position des moyens de roulage qui sont placés à l'arrière du bâti au lieu d'être placés entre les deux parties amont et aval.We can provide side gauge wheels but this does not seem ideal. In Figure 3, there is shown an arrangement with a different frame which consists of the same working tools. The difference lies in the position of the rolling means which are placed at the rear of the frame instead of being placed between the two upstream and downstream parts.
Les références des éléments identiques sont conservées. On note également la présence d'un bâti 10 en deux parties, l'une amont 22 et l'autre aval 24, par rapport au sens de déplacement de l'ensemble. Chacune de ces parties est elle-même réalisée en deux éléments 22-1, 22-2 ; 24-1, 24-2 articulés par rapport au bâti, suivant un axe parallèle au sens d'avancement. Ce bâti est porté par un train 16 de roues 18, en l'occurrence deux roues disposées à l'arrière du dispositif. Le fonctionnement est strictement identique au précédent. Dans la description ci-dessus, il est prévu deux parties l'une amont et l'autre aval afin d'atteindre un espace inter-rangs de faible largeur mais si l'on utilise une seule partie, on obtient également un excellent travail de déchαumαge et éventuellement de mise en place de semences. Dans ce cas, l'espace entre deux sillons est de X au lieu de S.The references of identical elements are kept. We also note the presence of a frame 10 in two parts, one upstream 22 and the other downstream 24, relative to the direction of movement of the assembly. Each of these parts is itself made up of two elements 22-1, 22-2; 24-1, 24-2 articulated with respect to the frame, along an axis parallel to the direction of advance. This frame is carried by a train 16 of wheels 18, in this case two wheels arranged at the rear of the device. The operation is strictly identical to the previous one. In the description above, two parts are provided, one upstream and the other downstream in order to achieve a narrow inter-row space, but if only one part is used, excellent work is also obtained. decumpling and possibly placing seeds. In this case, the space between two grooves is X instead of S.
On note surtout que la terre est parfaitement préparée car la terre est ouverte de façon linéaire par chacun des disques. Ensuite, les socs 36-1 de la première rangée, par exemple 37-1, retournent la terre sur une faible profondeur certes mais forment des remontées longitudinales de terre, comme des bourrelets, de part et d'autre de chaque sillon proprement dit. Lorsque les socs 36-1 de la seconde rangée 39-1 attaquent la terre ouverte par les disques correspondants, ils ramènent également la terre des remontées réalisées par les socs de la première rangée.We note above all that the earth is perfectly prepared because the earth is opened in a linear fashion by each of the discs. Then, the plowshares 36-1 of the first row, for example 37-1, turn the earth over a shallow depth certainly but form longitudinal lifts of earth, like beads, on either side of each groove proper. When the plowshares 36-1 of the second row 39-1 attack the earth opened by the corresponding disks, they also bring back the earth of the lifts made by the plowshares of the first row.
Le terre est ainsi non seulement travaillée verticalement mais également déplacée suivant une sorte de sinusoïde, ce qui lui confère des qualités d'ameublissement et d'aération avec une grande aptitude à faire germer les semences éventuellement et avantageusement plantées en aval. Cette qualité de travail est engendrée par la disposition et le choix des outils retenus. The soil is thus not only worked vertically but also moved in a sort of sinusoid, which gives it qualities of loosening and aeration with a great ability to germinate seeds possibly and advantageously planted downstream. This quality of work is generated by the arrangement and the choice of tools used.
