Description

La présente invention concerne un engin de déblayage du sol sur une certaine épaisseur et une largeur donnée, destiné à rejeter la terre et les corps qui y sont enfouis souvent sur au moins un côté de l'engin. Plus particulièrement, l'invention concerne un engin de déminage, rejetant, en les faisant exploser le cas échéant, les mines enfouies dans la terre jusqu'à une profondeur donnée, sur un ou les deux côtés de l'engin afin de dégager un passage non dangereux pour des véhicules, ou des hommes, sur une largeur suffisante.The present invention relates to a machine for clearing the ground over a certain thickness and a given width, intended to reject the earth and the bodies which are often buried thereon on at least one side of the machine. More particularly, the invention relates to a demining device, rejecting, by detonating them if necessary, the mines buried in the earth to a given depth, on one or both sides of the device in order to clear a passage not dangerous for vehicles, or men, over a sufficient width.

En temps de guerre, le passage de véhicules, camions, blindés ou autres, sur des terrains dont on ne s'était pas encore assuré la maitrise, nécessite le contrôle de la sécurité du passage, c'est-à-dire une vérification de la présence ou non de mines ou autres pièges et, le cas échéant, un déminage.In wartime, the passage of vehicles, trucks, armored vehicles or other vehicles, on land which has not yet been controlled, requires the control of the security of the passage, i.e. a verification of whether or not there are mines or other booby-traps and, where appropriate, mine clearance.

Si sur des terrains relativement accidentés la pose des mines s'effectue toujours à la main et le déminage également (à l'aide d'un outil ou de la baïonnette), sur les terrains plats, où l'avance peut être rapide, la pose de nombreuses mines peut se faire plus rapidement, sur de grandes largeurs, avec des engins de pose. De ce fait, le déminage à la main va être très long. Or l'urgence du passage des véhicules rend nécessaire un déminage rapide.If on relatively uneven terrain the laying of mines is always carried out by hand and also mine clearance (using a tool or bayonet), on flat terrain, where the advance can be rapid, the Many mines can be laid more quickly, over large widths, with laying machines. As a result, mine clearance by hand will be very long. The urgency of the passage of vehicles makes rapid demining necessary.

L'emploi d'un engin de déminage rapide du terrain va donc être nécessaire.The use of a rapid mine clearance device will therefore be necessary.

On peut envisager différentes méthodes de travail pour engin de ce type.We can consider different working methods for a machine of this type.

L'une d'elles consisterait à faire exploser systématiquement toutes les mines situées sur le passage que l'on veut dégager au moyen d'un engin battant le sol et situé à l'avant d'un véhicule.One of them would consist in systematically detonating all the mines located on the passage that we want to clear by means of a machine beating the ground and located at the front of a vehicle.

Cette méthode a toutefois des inconvénients qui sont que le battage du sol risquerait d'une part de ne pas faire exploser les mines disposées plus profondément et d'autre part de renvoyer en arrière les mines déterrées, sous les roues ou les chenilles de l'engin porteur.This method, however, has drawbacks which are that the threshing of the ground would risk on the one hand not to detonate the mines arranged more deeply and on the other hand to return back the mines unearthed, under the wheels or the tracks of the carrier vehicle.

En conséquence, ce dernier devrait avancer lentement pour laisser le temps aux mines soulevées d'exploser avant de rouler à l'endroit où elles sont retombées. Ceci ralentirait fort le déminage.As a result, the latter should move slowly to allow the raised mines to explode before rolling to the place where they have fallen. This would greatly slow down mine clearance.

Autre inconvénient et cause de ralentissement, cette méthode par les projections et la poussière dégagée nuit à la visibilité du conducteur.Another disadvantage and cause of slowing down, this method by projections and the dust released harms the visibility of the driver.

Une autre méthode consiste à déblayer le sol sur une certaine profondeur et une largeur au moins égale à la largeur des véhicules à faire passer en rejetant la terre et les obstacles qui s'y trouvent sur au moins l'un des côtés du passage dégagé.Another method consists in clearing the ground to a certain depth and a width at least equal to the width of the vehicles to be passed by rejecting the earth and the obstacles which are there on at least one of the sides of the clear passage.

La présente invention atteint le but poursuivi en réalisant un engin de déblayage fonctionnant selon cette dernière méthode et caractérisé en ce qu'il comporte un bâti, monté à l'avant du véhicule, sur au moins un côté duquel sont fixés des corps de labour disposés l'un derrière l'autre par rapport au sens d'avancement, avec un décalage latéral de manière à ce que la terre, déblayée et rejetée latéralement avec les objets qu'elle contient par un corps de labour, soit reprise par le corps de labour suivant pour être rejetée plus loin, latéralement dans la même direction, avec la terre déblayée par celui-ci.The present invention achieves the aim pursued by producing a mucking machine operating according to this latter method and characterized in that it comprises a frame, mounted at the front of the vehicle, on at least one side of which are arranged plowing bodies arranged one behind the other with respect to the direction of travel, with a lateral offset so that the earth, cleared and rejected laterally with the objects it contains by a plow body, is taken up by the body of next plowing to be thrown further, laterally in the same direction, with the earth cleared by it.

Selon une réalisation préférentielle, les corps de labour sont disposés des deux côtés du bâti, en deux séries identiques, chacune rejetant la terre latéralement de son côté.According to a preferred embodiment, the plowing bodies are arranged on the two sides of the frame, in two identical series, each rejecting the earth laterally on its side.

L'invention sera mieux comprise au moyen d'un exemple de réalisation représenté sur le dessin annexé et décrit ci-­après. On a représenté :

  • Figure 1 : un exemple de réalisation de l'engin avec deux séries de trois disques;
  • Figure 2 : une vue latérale des corps de labour, et
  • Figure 3 : une vue schématique de l'engin en position de travail dans le sol.
The invention will be better understood by means of an exemplary embodiment shown in the accompanying drawing and described below. We have represented:
  • Figure 1: an embodiment of the machine with two sets of three discs;
  • Figure 2: a side view of the plow bodies, and
  • Figure 3: a schematic view of the machine in the working position in the ground.

L'engin selon l'invention comporte un bâti 1 constitué de deux poutres 6, 6′ convergeant vers l'avant, reliées entre elles par une traverse 5 au moyen de deux goupilles 8, 9. Le bâti 1 est relié au véhicule porteur, ou pousseur, par au moins trois points d'attache 7. Les poutres 6 et 6′ sont reliées à l'avant, grâce à deux chapes 10 et 11, par un axe 12.The machine according to the invention comprises a frame 1 consisting of two beams 6, 6 ′ converging towards the front, connected to each other by a cross-member 5 by means of two pins 8, 9. The frame 1 is connected to the carrier vehicle, or pusher, by at least three attachment points 7. The beams 6 and 6 ′ are connected at the front, by means of two yokes 10 and 11, by an axis 12.

Sur chacune des poutres 6, 6′ sont disposés trois corps de labour 2, 3, 4 constitués par un support vertical 13 solidaire de la poutre, sur lequel est monté à rotation un disque 14. Ces corps de labour sont disposés sur les poutres 6 et 6′ de manière à rejeter la terre de part et d'autre de l'engin lors de l'avancement selon la flèche A. Les disques 14 ont des diamètres croissant de l'avant vers l'arrière de l'engin par rapport au sens A de l'avancement.On each of the beams 6, 6 ′ are arranged three plowing bodies 2, 3, 4 constituted by a vertical support 13 integral with the beam, on which a disc 14 is mounted for rotation. These plowing bodies are arranged on the beams 6 and 6 ′ so as to reject the earth on either side of the machine during advancement according to arrow A. The discs 14 have diameters increasing from the front towards the rear of the machine with respect to in direction A of the progress.

Les disques de chacune des poutres 6 et 6′ sont disposés dans un plan faisant avec la direction d'avancement A un angle α. Cet angle, dit angle d'ouverture, peut varier en fonction des terres travaillées et des résultats que l'on veut obtenir. Il peut varier également en fonction du diamètre du disque 13. De ce fait, il n'est pas obligatoirement le même pour tous les disques de l'engin. L'angle α peut varier généralement entre 35 et 55°.The discs of each of the beams 6 and 6 ′ are arranged in a plane forming with the direction of advance A at an angle α. This angle, called the opening angle, can vary depending on the land worked and the results that one wants to obtain. It can also vary depending on the diameter of the disc 13. Therefore, it is not necessarily the same for all the discs of the machine. The angle α can generally vary between 35 and 55 °.

La pénétration du disque dans le sol est favorisée par l'existence d'un angle d'entrure β (figure 2). De même que l'angle d'ouverture α, cet angle d'entrure β varie en fonction des paramètres précités. Il se situe généralement entre 15 et 25°.The penetration of the disc into the ground is favored by the existence of an entry angle β (Figure 2). Like the opening angle α, this entry angle β varies according to the aforementioned parameters. It is generally between 15 and 25 °.

Le fonctionnement de l'engin est le suivant.The operation of the machine is as follows.

Monté à l'avant d'un véhicule, par exemple un char, l'engin est poussé dans le sens de la flèche A. Les disques pénètrent dans le sol jusqu'à une profondeur de travail pré-réglée. Dans le cas représenté, cette profondeur est d'environ 30 cm.Mounted in front of a vehicle, for example a tank, the machine is pushed in the direction of arrow A. The discs penetrate the ground to a pre-set working depth. In the case shown, this depth is approximately 30 cm.

Placés avec décalage progressif vers l'arrière et vers l'extérieur sur chaque poutre 6, 6′, les disques 13 permettent de déblayer de grands volumes de terre. Leur façon de travailler est différente de celle d'une charrue. En effet, chaque disque rejette sur le disque suivant le volume de terre qu'il dégage, cette méthode de travail est facilité par le fait que les diamètres des disques 13 vont croissant de l'avant vers l'arrière et vers l'extérieur.Placed with progressive offset backwards and outwards on each beam 6, 6 ′, the discs 13 make it possible to clear large volumes of soil. Their way of working is different from that of a plow. Indeed, each disc rejects on the disc according to the volume of soil which it releases, this working method is facilitated by the fact that the diameters of the discs 13 increase from front to back and outwards.

Avec la terre, les objets qui gisent dessus ou qui y sont enfouis, notamment des mines, sont progressivement repoussés vers le côté. Les mines peuvent exploser lorsqu'elles sont heurtées ou retournées par les disques, mais elles ne peuvent pas endommager le véhicule situé très en arrière.With the earth, objects lying on it or buried there, notably mines, are gradually pushed to the side. Mines may explode when struck or returned by discs, but they cannot damage the vehicle far behind.

La largeur de travail de l'engin est variable. Dans l'exemple décrit ici, on a une largeur de travail d'environ 4,50 m. Cette largeur peut être réduite en diminuant la largeur de la traverse 5. Pour des largeurs très réduites, 2,25 m par exemple, une seule poutre 6 peut être utilisée avec une seule série de corps de labour rejetant la terre d'un côté. La largeur de travail à régler dépend surtout de la largeur des véhicules que l'on veut faire passer.The working width of the machine is variable. In the example described here, there is a working width of around 4.50 m. This width can be reduced by reducing the width of the crosspiece 5. For very reduced widths, 2.25 m for example, a single beam 6 can be used with a single series of plow bodies rejecting the earth on one side. The working width to be set depends mainly on the width of the vehicles that you want to pass.

La réalisation de l'engin peut prendre des formes différentes:
disques de même diamètre ; une ou deux poutres ; moyens de montage sur le véhicule pousseur. On peut prévoir une roulette de support à l'avant pour déterminer la profondeur de travail à partir d'un réglage en hauteur de celle-ci. Bien entendu, le nombre de corps de labour peut être différent de trois. Ces corps peuvent être également des socs et des versoirs fonctionnant de la même façon, ou tout autre instrument de labour pouvant fournir le même résultat.The realization of the machine can take different forms:
discs of the same diameter; one or two beams; mounting means on the pusher vehicle. A support roller can be provided at the front to determine the working depth from a height adjustment thereof. Of course, the number of plows can be different from three. These bodies can also be plowshares and mouldboards working in the same way, or any other plowing instrument that can provide the same result.

La jonction entre les poutres 6 et 6′ à l'avant peut se faire sans l'axe 12, avec seulement des butées, car les forces exercées sur les corps de labour pendant le travail suffisent à maintenir la convergence des poutres 6 et 6′. L'engin peut être replié sur le véhicule pousseur pour son transport, les poutres 6 et 6′ pouvant alors être rabattues avec leurs corps de labour sur les bords de l'engin. Le relèvement et la mise en place de l'engin peuvent être effectués au moyen de vérins hydrauliques ou de tout autres dispositifs analogues.The junction between the beams 6 and 6 ′ at the front can be done without the axis 12, with only stops, because the forces exerted on the plow bodies during work are sufficient to maintain the convergence of the beams 6 and 6 ′ . The machine can be folded back on the pusher vehicle for its transport, the beams 6 and 6 ′ can then be folded down with their plowing bodies on the edges of the machine. The lifting and positioning of the machine can be carried out by means of hydraulic cylinders or any other similar device.
