Abstract

La présente invention concerne une benne pour produits compactables comportant un organe de compactage mobile par rotation autour d'une axe solidaire du fond de la benne et situé à la partie inférieure de l'organe de compactage. Conformément à l'invention l'organe de compactage (8) a une forme telle qu'il s'applique contre au moins une partie d'une paroi (5, 7) de la benne (1) sensiblement parallèle à une direction et est articulé à son extrémité inférieure autour d'un axe (6) situé au fond de la benne, décalé vers le centre de la benne et sesiblement parallèle à ladite direction, son extrémité supérieure comportant au moins un moyen d'accouplement (12) avec un organe de traction et/ou de poussée éventuellement indépendant de la benne. L'invention s'applique aux bennes notamment dites "multibennes" pour accroître leur capacité de transport dans le cas de produits compactables.The present invention relates to a bucket for compactable products comprising a compacting member movable by rotation about an axis integral with the bottom of the bucket and located at the bottom of the compacting member. According to the invention the compacting member (8) has a shape such that it is applied against at least part of a wall (5, 7) of the bucket (1) substantially parallel to a direction and is articulated at its lower end around an axis (6) located at the bottom of the bucket, offset towards the center of the bucket and substantially parallel to said direction, its upper end comprising at least one coupling means (12) with a traction and / or thrust member possibly independent of the bucket. The invention applies to skips, in particular so-called "skips" to increase their transport capacity in the case of compactable products.

Description

La présente invention concerne les bennes utilisées pour le transport des produits compactables tels que les matières organiques, les déchets ménagers, les tournures métalliques et autres et plus spécialement les bennes ou conteneurs qui peuvent être alternativement utilisés pour le stockage temporaire et le transport de produits les plus divers notamment selon le système dit "multibennes".The present invention relates to skips used for the transport of compactable products such as organic materials, household waste, metallic turnings and others and more especially skips or containers which can be alternately used for the temporary storage and transport of products more diverse, in particular according to the so-called "multi-tipper" system.

Il est usuel de munir les bennes spécialisées pour le transport de produits compactables, notamment les bennes affectées à l'enlèvement des ordures ménagères, d'un mécanisme de compactage comportant une paroi mobile à l'intérieur du volume de chargement, le mouvement de cette paroi mobile étant commandé par un organe moteur puissant qui lui est propre, notamment un systéme de vérins hydrauliques. De telles bennes pour détritus compactables sont décrites par exemple dans FR-A-1.189.280, FR-A-2.215.312 ou FR-A-2.293.306. Ces bennes sont d'une utilisation spécifique et le dispositif de compactage qui doit être monté à demeure occupe un volume important et est d'un poids notable, ce qui réduit d'autant la capacité de chargement du véhicule sur lequel sont montés la benne et le dispositif de compactage.It is customary to provide specialized skips for the transport of compactable products, in particular skips used for the removal of household waste, with a compacting mechanism comprising a movable wall inside the volume of loading, the movement of this movable wall being controlled by a powerful motor member of its own, in particular a system of hydraulic cylinders. Such compactable litter bins are described for example in FR-A-1,189,280, FR-A-2,215,312 or FR-A-2,293,306. These skips are for a specific use and the compacting device which must be permanently mounted occupies a large volume and is of significant weight, which reduces the loading capacity of the vehicle on which the skip is mounted and the compacting device.

On a proposé également dans FR-A-1.545.840, FR-A-2.421.820 et FR-A-2.362.778 des conteneurs ou bacs comportant des dispositifs presseurs. Dans FR-A-2.362.778 notamment ce dispositif presseur est constitué par une paroi mobile qui est articulée autour d'un axe situé au fond du caisson et qui coopère de façon étanche avec les faces latérales du caisson et une paroi cylindrique supérieure centrée sur l'axe, le déplacement de la plaque et sa mise en pression étant commandés par une différence dans les pressions régnant sur ses deux faces. Les dispositifs décrits dans ces brevets occupent une partie importante du volume du conteneur et nécessitent des moteurs d'entraînement spécifiques. En outre leur poids s'ajoute au poids mort de la benne ou du conteneur lorsque la benne ou le conteneur est utilisé pour le stockage ou le transport de matériaux non compactables.It has also been proposed in FR-A-1,545,840, FR-A-2,421,820 and FR-A-2,362,778 containers or trays comprising pressing devices. In FR-A-2,362,778 in particular this pressing device is constituted by a movable wall which is articulated around an axis located at the bottom of the box and which cooperates in leaktight manner with the lateral faces of the box and an upper cylindrical wall centered on the axis, the displacement of the plate and its pressurization being controlled by a difference in the pressures prevailing on its two faces. The devices described in these patents occupy a large part of the volume of the container and require specific drive motors. In addition, their weight is added to the dead weight of the container or container when the container or container is used for the storage or transport of non-compactable materials.

US-A-3.903.461 décrit une benne pour produits compactables comportant un organe de compactage mobile par rotation autour d'un axe solidaire du fond de la benne et situé à la partie inférieure de l'organe de compactage, l'organe de compactage ayant une forme telle qu'il s'applique contre au moins une partie d'une paroi de la benne sensiblement parallèle à une direction et articulé à son extrémité inférieure autour d'un axe situé au fond de la benne et sensiblement parallèle à ladite direction. Toutefois dans cette benne l'axe d'articulation de l'organe de compactage est situé au fond de la benne au pied de la paroi contre laquelle vient s'appliquer l'organe de compactage qui, de ce fait, a une course angulaire réduite et qui tasse les produits contre le fond de la benne à proximité de l'axe d'articulation alors qu'un tassement logique doit repousser les produits contre l'autre paroi d'extrémité de la benne et les tasser essentiellement contre cette paroi.US-A-3,903,461 describes a bucket for compactable products comprising a compacting member movable by rotation about an axis integral with the bottom of the bucket and located at the lower part of the compacting member, the compacting member having a shape such that it is applied against at least part of a wall of the bucket substantially parallel to a direction and articulated at its lower end about an axis located at the bottom of the bucket and substantially parallel to said direction . However in this bucket the articulation axis tion of the compacting member is located at the bottom of the bucket at the foot of the wall against which the compacting member is applied which, therefore, has a reduced angular travel and which compacts the products against the bottom of the bucket close to the hinge pin while a logical compaction must push the products against the other end wall of the bucket and compact them essentially against this wall.

La présente invention a pour but de remédier à ces divers inconvénients et de créer un dispositif de compactage pour benne qui soit simple, qui ne réduise pas sensiblement le volume utile de la benne, qui ne nécessite pas de moteur d'entraînement propre, dont l'efficacité de l'action de compression soit élevée à tout stade de remplissage de la benne et qui puisse être démonté facilement de la benne en cas d'utilisation de celle-ci pour des matériaux non compactables.The object of the present invention is to remedy these various drawbacks and to create a compacting device for a bucket which is simple, which does not substantially reduce the useful volume of the bucket, which does not require its own drive motor, the l T he effectiveness of the compression action is high at any stage of filling the bucket and which can be easily dismantled from the bucket if it is used for non-compactable materials.

Ce but est atteint conformément à l'invention par le perfectionnement selon lequel l'organe de compactage qui a une forme telle qu'il s'applique contre au moins une partie d'une paroi de la benne sensiblement parallèle à une direction, est articulé à son extrémité inférieure autour d'un axe situé au fond de la benne et sensiblement parallèle à ladite direction, la benne pour produits compactables étant caractérisée en ce que ledit axe d'articulation de l'organe de compactage est décalé vers le centre de la benne et en ce que l'extrémité supérieure de l'organe de compactage comporte au moins un moyen d'accouplement avec un organe de traction et/ou de poussée éventuellement indépendant de la benne.This object is achieved in accordance with the invention by the improvement according to which the compacting member which has a shape such that it is applied against at least part of a wall of the bucket substantially parallel to a direction, is articulated at its lower end around an axis located at the bottom of the bucket and substantially parallel to said direction, the compactable material bucket being characterized in that said articulation axis of the compacting member is offset towards the center of the bucket and in that the upper end of the compacting member comprises at least one coupling means with a traction and / or thrust member possibly independent of the grab.

Du fait de la forme de l'organe de compactage, sa présence réduit au minimum le volume utile de la benne. L'axe d'articulation de l'organe de compactage situé au fond de la benne étant décalé vers le centre de la benne, le compactage comporte un soulèvement et un transport de la matière vers l'extrémité opposée de la benne, ce qui accroît le volume libéré pour le chargement d'un nouveau volume de matière et améliore le compactage, la composante du déplacement selon la longueur de la benne ou direction de compactage étant plus grande qu'avec une articulation dans le plan d'une paroi plane de compactage. Enfin, du fait du moyen d'accouplement, la force de compactage peut être fournie par des moteurs indépendants de la benne par exemple la prise de force d'un tracteur, la force de traction d'un camion ou d'un engin auto-moteur, un treuil, etc. Il rentre toutefois également dans le cadre de l'invention de prévoir un moyen de poussée ou de traction agissant entre l'organe de compactage et la benne elle-même, tel qu'un ou plusieurs vérins à vis ou hydrauliques qui peuvent être entrai- nés par la prise de force d'un tracteur ou alimentés à partir du circuit hydraulique d'un engin séparé, le moyen de poussée ou de traction étant de préférence amovible.Due to the shape of the compacting member, its presence minimizes the useful volume of the bucket. The axis of articulation of the compacting member located at the bottom of the bucket being offset towards the center of the bucket, compacting involves lifting and transporting the material towards the opposite end of the bucket, which increases the volume released for loading a new volume of material and improving compaction, the displacement component along the length of the bucket or direction of compaction being greater than with an articulation in the plane of a plane wall of compaction. Finally, due to the coupling means, the compaction force can be provided by motors independent of the bucket, for example the power take-off of a tractor, the traction force of a truck or a self-propelled machine. engine, winch, etc. However, it also falls within the scope of the invention to provide a means of pushing or pulling acting between the compacting member and the bucket itself, such as one or more screw or hydraulic jacks which can be driven born by the PTO of a tractor or fed from the hydraulic circuit of a separate machine, the pushing or pulling means being preferably removable.

De préférence et selon une autre caractéristique, l'axe d'articulation situé à l'extrémité inférieure de l'organe de compactage est démontable de manière à rendre l'organe de compactage amovible. Ceci permet de démonter l'organe de compactage de la benne lorsque celle-ci est utilisée pour des produits non compactables.Preferably and according to another characteristic, the hinge pin located at the lower end of the compacting member is removable so as to make the compacting member removable. This makes it possible to dismantle the compacting member of the bucket when the latter is used for non-compactable products.

Selon une autre caractéristique l'axe d'articulation de l'organe de compactage est mobile selon la direction longitudinale de la benne. Le déplacement de l'axe d'articulation peut être assuré par un dispositif ne produisant pas de puissance de compactage ou par un dispositif coopérant à l'opération de compactage. A titre d'exemple le moyeu de l'axe d'articulation peut être déplaçable par un engrenage à vis sans fin. Cette caractéristique permet, en début de chargement, de rapprocher le dispositif de compactage de l'extrémité opposée de la benne et de limiter le volume de matière compactéeau cours des premières opérations, ce qui assure un compactage plus efficace et plus homogène.According to another characteristic, the articulation axis of the compacting member is movable in the longitudinal direction of the bucket. The displacement of the articulation axis can be ensured by a device not producing compaction power or by a device cooperating in the compacting operation. By way of example, the hub of the hinge pin can be moved by a worm gear. This characteristic makes it possible, at the start of loading, to bring the compacting device closer to the opposite end of the bucket and to limit the volume of material compacted during the first operations, which ensures more efficient and more homogeneous compaction.

Selon un mode de réalisation particulier, le dispositif de compactage est constitué par une partie de la paroi et une partie du fond de la benne qui sont solidaires et articulés autour de l'autre partie du fond de la benne par l'axe d'articulation du dispositif de compactage.According to a particular embodiment, the compacting device consists of a part of the wall and a part of the bottom of the bucket which are integral and articulated around the other part of the bottom of the bucket by the hinge pin of the compacting device.

De préférence le moyen d'accouplement du dispositif de compactage est porté par un prolongateur rigide fixé rigidement et de préférence de façon amovible ou éclipsable sur le dispositif de compactage pour permettre d'écarter le moyen d'accouplement de l'axe d'articulation et d'accroître le bras de levier.Preferably the coupling means of the compacting device is carried by a rigid extension rigidly fixed and preferably removably or eclipsable on the compacting device to allow the coupling means to be moved away from the articulation axis and increase the lever arm.

Selon une autre caractéristique et lorsque le dispositif de compactage n'occupe qu'une fraction de la largeur de la benne, l'articulation sur le fond de la benne permet un basculement autour de l'axe perpendiculaire à l'axe d'articulation. Dans ce cas la forme de l'organe de compactage peut être telle qu'il s'adapte, dans les deux positions inclinées extrêmes, contre les côtés latéraux de la benne. Il peut également comporter des volets articulés sur l'organe de compactage principal pour assurer un volume engendré par la surface de l'organe de compactage dans ses différentes inclinaisons, qui occupe la totalité de la section de la benne. Cette forme de réalisation du dispositif de compactage permet d'accroître la pression unitaire de compactage. Ce même résultat peut être atteint en subdivisant l'organe de compactage en une pluralité d'éléments juxtaposés. Dans le cas d'une matière susceptible de fluer autour des bords de l'élément de compactage et lorsque celui-ci est subdivisé en plusieurs éléments juxtaposés, il est possible de prévoir des jupes fermant l'interstice entre éléments, l'élément déplacé positivement assurant, après un déplacement correspondant à la largeur de la jupe, l'entraînement des éléments adjacents. Du fait de l'angle de transmission des forces dans la masse compactée, une largeur de jupe assez faible donnant un faible retard aux éléments entraînés permet de concentrer la force de compactage sur l'élément déplacé positivement.According to another characteristic and when the compacting device occupies only a fraction of the width of the bucket, the articulation on the bottom of the bucket allows tilting around the axis perpendicular to the axis of articulation. In this case, the shape of the compacting member can be such that it adapts, in the two extreme inclined positions, against the lateral sides of the bucket. It may also include flaps articulated on the main compacting member to ensure a volume generated by the surface of the compacting member in its different inclinations, which occupies the entire section of the bucket. This embodiment of the compaction device makes it possible to increase the unit compaction pressure. This same result can be achieved by subdividing the compacting member into a plurality of juxtaposed elements. In the case of a material liable to creep around the edges of the compacting element and when the latter is subdivided into several juxtaposed elements, it is possible to provide skirts closing the interstice between elements, the element moved positively ensuring, after a movement corresponding to the width of the skirt, the driving of the adjacent elements. Due to the angle of transmission of the forces in the compacted mass, a fairly small skirt width giving a small delay to the driven elements makes it possible to concentrate the compacting force on the positively displaced element.

Le moyen d'accouplement peut être d'un type quelconque adapté au dispositif assurant la poussée ou la traction. Le moyen d'accouplement peut être démontable lorsqu'il serait susceptible d'interférer avec le dispositif assurant le chargement de la benne remplie. A titre d'exemples d'un tel moyen d'accouplement on peut citer un manchon rotulé dans lequel peut venir s'engager la flèche d'un engin de levage utilisé en poussée, la fourche d'un chariot ou la tige d'un vérin hydraulique, un oeil pour l'engagement du crochet d'un câble de treuil avec éventuellement des moyens de guidage du câble, un ciseau de traction ou de poussée qui peut éventuellement constituer un vérin manuel ou un vérin entraîné par la prise de force d'un tracteur ou par un vérin hydraulique. Le moyen d'accouplement peut comporter un limiteur de force ou de couple pour éviter la rupture des pièces mécaniques lorsqu'il existe des points durs dans la masse compactée.The coupling means can be of any type adapted to the device ensuring the pushing or pulling. The coupling means can be dismantled when it is likely to interfere with the device ensuring the loading of the filled bucket. Examples of such a coupling means include a swivel sleeve in which can engage the boom of a lifting machine used in thrust, the fork of a carriage or the rod of a hydraulic cylinder, an eye for engaging the hook of a winch cable with possibly cable guiding means, a pulling or pushing chisel which may possibly constitute a manual cylinder or a cylinder driven by the power take-off '' a tractor or a hydraulic cylinder. The coupling means may include a force or torque limiter to avoid breaking the mechanical parts when there are hard points in the compacted mass.

Dans le but d'accroître la force de compactage exercée par l'organe de compactage et de rendre éventuellement le dispositif de compactage amovible de la benne,le moyen d'accouplement avec l'organe de traction et/ou de poussée peut être constitué par un bras articulé à une de ses extrémités sur la benne autour d'un axe parallèle à l'axe d'articulation de l'organe de compactage et portant à son autre extrémité un galet monté à rotation autour d'un axe parallèle aux deux autres, le point d'action de l'organe de traction et/ou de poussée sur le bras se situant au-dessus du point d'articulation dudit bras sur la benne et entre ledit axe d'articulation sur la benne et l'axe de rotation du galet.With the aim of increasing the compacting force exerted by the compacting member and possibly making the compacting device removable from the bucket, the means of coupling with the traction and / or pushing member can be constituted by an arm articulated at one of its ends on the bucket about an axis parallel to the axis of articulation of the compacting member and carrying at its other end a roller mounted for rotation about an axis parallel to the other two , the point of action of the traction and / or pushing member on the arm lying above the point of articulation of said arm on the bucket and between said axis of articulation on the bucket and the axis of rotation of the roller.

Selon une autre caractéristique le moyen d'accouplement entre le bras de compactage et l'organe de traction et/ou de poussée est constitué par un dispositif à genouillère, les deux bielles de part et d'autre de la genouillère étant articulées directement ou indirectement sur un point du bras de compactage, d'une part, et sur un point fixe par rapport à la benne, d'autre part, et l'organe de traction et/ou de poussée agissant sur la genouillère pour écarter les deux points d'articulation en rapprochant la genouillère de la ligne joignant lesdits deux points.According to another characteristic, the coupling means between the compacting arm and the traction and / or thrust member consists of a toggle device, the two connecting rods on either side of the toggle being articulated directly or indirectly. on a point of the compacting arm, on the one hand, and on a fixed point relative to the bucket, on the other part, and the traction and / or thrust member acting on the toggle to separate the two points of articulation by bringing the toggle closer to the line joining said two points.

Selon une autre caractéristique le dispositif à genouillère est combiné avec le moyen d'accouplement à bras de levier et galet, le dispositif à genouillère n'agissant qu'après une première course de compression assurée par le moyen d'accouplement à bras de levier et galet.According to another characteristic, the toggle device is combined with the lever arm and roller coupling means, the toggle device acting only after a first compression stroke ensured by the lever arm coupling means and pebble.

Selon un mode de réalisation, le dispositif à genouillère comporte un bras en forme de bielle articulé sur la benne autour d'un axe fixe parallèle à celui du bras de compactage, un second bras articulé à l'extrémité libre dudit premier bras par la genouillère, un moyen moteur agissant sur l'un des deux bras, de préférence au voisinage du point d'articulation formant genouillère, pour accroître l'angle formé par les deux dits bras, l'extrémité du deuxième bras étant articulée sur le bras de compactage. Selon un mode de réalisation préférentiel l'extrémité du deuxième bras est articulée sur le bras de compactage par l'intermédiaire d'une bielle articulée à une extrémité sur ledit bras de compactage et à son autre extrémité à l'extrémité dudit second bras, la rotation de ladite bielle dans le sens résultant de la poussée du second bras lors de l'accroissement de l'angle formé entre les deux premiers bras, étant limitée par une butée solidaire du bras de compactage et le point d'articulation entre le second bras et la bielle étant poussé, en fin de course, vers la ligne joignant les points d'articulation des deux autres extrémités par mise en butée du deuxième bras sur une butée solidaire du bras de compactage.According to one embodiment, the toggle joint device comprises an arm in the form of a rod articulated on the bucket around a fixed axis parallel to that of the compacting arm, a second arm articulated at the free end of said first arm by the knee joint , a motor means acting on one of the two arms, preferably in the vicinity of the articulation point forming a toggle joint, to increase the angle formed by the two said arms, the end of the second arm being articulated on the compacting arm . According to a preferred embodiment, the end of the second arm is articulated on the compacting arm by means of a connecting rod articulated at one end on said compacting arm and at its other end at the end of said second arm, the rotation of said connecting rod in the direction resulting from the thrust of the second arm when the angle formed between the first two arms is increased, being limited by a stop integral with the compacting arm and the point of articulation between the second arm and the connecting rod being pushed, at the end of the race, towards the line joining the points of articulation of the other two ends by abutment of the second arm on an abutment secured to the compacting arm.

Selon une autre caractéristique le moyen moteur entraînant le dispositif de démultiplication est constitué par le bras à galet. Dans ce cas le déplacement du bras à galet est de préférence transmis au dispositif à genouillère par une bielle de liaison articulée sur l'axe d'articulation formant genouillère. Le dispositif à course morte est réalisé par un retard à la solidarisation entre la bielle de liaison et le bras à galet sur la course initiale de la rotation dudit bras à galet.According to another characteristic, the drive means driving the reduction device consists of the roller arm. In this case the movement of the roller arm is preferably transmitted to the toggle device by a connecting rod link articulated on the articulation axis forming a toggle joint. The dead-stroke device is produced by a delay in the connection between the connecting rod and the roller arm on the initial stroke of the rotation of said roller arm.

Selon une autre caractéristique le mouvement de retour du bras à galet est transmis positivement au dispositif à genouillère pour assurer le repliement de ce dernier.According to another characteristic, the return movement of the roller arm is transmitted positively to the toggle device to ensure the folding of the latter.

Selon une autre caractéristique et dans le cas en particulier de bennes parallélipipédiques à paroi arrière amovible ou constituée par des portes ouvrantes ou un panneau basculant, le dispositif de compactage est indépendant de la benne et amovible ou articulé de façon basculante sur un axe transversal à l'arrière de la benne et il comporte, en combinaison, un caisson et le bras de compactage articulé au voisinage de l'un des bords du caisson.According to another characteristic and in the case in particular of parallelepipedic buckets with removable rear wall or constituted by opening doors or a tilting panel, the compacting device is independent of the bucket and removable or pivotally articulated on an axis transverse to the 'rear of the bucket and it comprises, in combination, a box and the compacting arm articulated in the vicinity of one of the edges of the box.

Le dispositif de compactage peut également être utilisé en combinaison avec une cuve comme dispositif de broyage pour de nombreux produits tels que caisses en bois ou en carton, palettes, verres, etc., et notamment comme broyeur dégrossisseur en amont des broyeurs classiques.The compacting device can also be used in combination with a tank as a grinding device for many products such as wooden or cardboard boxes, pallets, glasses, etc., and in particular as a roughing mill upstream of conventional mills.

Dans les dessins la référence 1 désigne la benne dans son ensemble et les parois verticales latérales de celle-ci, la référence 2 les nervures de renfort, la référence 3 la tôle de fond de la benne, la référence 4 la paroi d'extrémité de la benne en direction de laquelle s'effectue le compactage et la référence 5 la paroi transversale opposée contre laquelle vient prendre appui l'organe de compactage.In the drawings, the reference 1 designates the bucket as a whole and the vertical side walls thereof, the reference 2 the reinforcing ribs, the reference 3 the bottom sheet of the bucket, the reference 4 the end wall of the bucket in the direction of which the compacting is carried out and the reference 5 the opposite transverse wall against which the compacting member comes to bear.

Conformément à l'invention, le dispositif de compactage est articulé autour d'un axe 6 parallèle à la paroi 5 et situé à proximité du fond 3 en étant décalé vers la paroi 4 par rapport à la paroi 5. Dans ce genre de benne et notamment dans celles dites "multi-bennes" qui sont destinées à être chargées sur une plate-forme, la paroi 5 est verticale et réunie au fond 3 par un pan coupé 7. Le dispositif de compactage 8 est donc formé de trois sections assemblées rigidement, l'une 9 susceptible de venir s'appliquer contre le fond 3, l'autre 10 s'appliquant contre le pan coupé 7 et la troisième 11 qui vient contre la paroi verticale 5. L'organe d'accouplement 12 est articulé à l'extrémité de la section 11. Dans le mode de réalisation de la figure 1, l'organe d'accouplement est un manchon conique rotulé en 13 qui permet d'exercer la poussée assurant le compactage avec la fourche 14 d'un chariot élévateur.According to the invention, the compacting device is articulated around an axis 6 parallel to the wall 5 and located near the bottom 3 while being offset towards the wall 4 relative to the wall 5. In this type of bucket and in particular in those called "multi-skips" which are intended to be loaded on a platform, the wall 5 is vertical and joined to the bottom 3 by a cutaway 7. The compacting device 8 is therefore formed of three sections rigidly assembled , one 9 likely to be applied against the bottom 3, the other 10 applying against the cutaway 7 and the third 11 which comes against the vertical wall 5. The coupling member 12 is articulated the end of section 11. In the embodiment of Figure 1, the coupling member is a conical sleeve swiveled at 13 which allows to exert the thrust ensuring compaction with the fork 14 of a forklift .

Au repos et comme représenté en pointillés, le dispositif de compactage est appliqué contre la paroi 5 et le manchon d'accouplement 12 pend à l'extérieur de la benne. Lorsque la benne est remplie avec le matériau non compacté, il est possible, avec un chariot élévateur, d'engager la fourche 14 de ce dernier dans l'ouverture du manchon 12 pour l'amener à l'horizontale puis d'exercer une poussée pour amener l'organe de compactage 8 vers la position représentée en traits pleins. Le compactage s'effectue selon les flèches F représentées en traits mixtes et, lorsque l'organe de compactage 8 est ramené en position de repos, un espace vide se trouve libéré en V dans lequel on peut charger une masse supplémentaire de matériau compactable qui pourra elle-même être compactée.At rest and as shown in dotted lines, the compacting device is applied against the wall 5 and the coupling sleeve 12 hangs outside the bucket. When the bucket is filled with the uncompacted material, it is possible, with a forklift, to engage the fork 14 of the latter in the opening of the sleeve 12 to bring it to the horizontal and then to exert a thrust to bring the compacting member 8 to the position shown in solid lines. The compacting is carried out according to the arrows F shown in phantom and when the compacting member 8 is brought back to the rest position, an empty space is freed in V in which an additional mass of compactable material can be loaded which can itself be compacted.

La face avant de l'organe de compactage 8 qui peut avoir toute constitution et être en tôle pleine ou ajourée ou constituée par des barreaux, est garnie d'arêtes 16 qui peuvent concentrer la pression sur des éléments durs écrasables, tels par exemple des caisses de bois ou analogues, pour en assurer le broyage. Dans les autres figures, les mêmes références sont utilisées pour désigner les mêmes éléments que dans la figure 1 ou des éléments équivalents.The front face of the compacting member 8 which can have any constitution and be made of solid or perforated sheet metal or constituted by bars, is provided with edges 16 which can concentrate the pressure on hard crushable elements, such as for example boxes of wood or the like, for grinding. In the other figures, the same references are used to designate the same elements as in FIG. 1 or equivalent elements.

Dans le mode de réalisation de la figure 2, l'organe de compactage 8 est constitué par les parties 5', 7' et 3' qui constituent la paroi 5 et le pan coupé 7 de la benne ainsi qu'une tôle doublant le fond 3 jusqu'au niveau de l'axe 6. L'organe de compactage est complété par des parois latérales 17 qui s'appliquent en pouvant coulisser contre les parois 1. Les arêtes 16 sont portées par les parois mobiles 5'-7' de la benne qui constituent l'organe de compactage. Ce mode de réalisation permet de réduire le poids mort de la benne par rapport au mode de réalisation de la figure 1, mais l'organe de compactage ne peut pas être amovible de sorte que ce mode de réalisation est préférentiel dans le cas d'une benne utilisée spécifiquement pour des produits compactables.In the embodiment of Figure 2, the compacting member 8 is constituted by the parts 5 ', 7' and 3 'which constitute the wall 5 and the cutaway 7 of the bucket as well as a sheet lining the bottom 3 up to the level of the axis 6. The compacting member is completed by side walls 17 which are applied by being able to slide against the walls 1. The edges 16 are carried by the movable walls 5'-7 'of the bucket which constitutes the compacting member. This embodiment makes it possible to reduce the dead weight of the bucket compared to the embodiment of FIG. 1, but the compacting member cannot be removable so that this embodiment is preferable in the case of a bucket used specifically for compactable products.

Dans ce mode de réalisation, l'opération de compactage est assurée en utilisant la force de traction du câble 18 du treuil 19 d'un camion 20 qui se met en appui par son pare-chocs contre la face 4 de la benne. Pour accroître le bras de levier, un prolongateur 21 qui peut être télescopique, est fixé de façon amovible sur le bord supérieur de l'organe de compactage 8, ce prolongateur portant l'oeil sur lequel vient s'accrocher le crochet du câble 18.In this embodiment, the compacting operation is ensured by using the tensile force of the cable 18 of the winch 19 of a truck 20 which is supported by its bumper against the face 4 of the bucket. To increase the lever arm, an extension 21 which can be telescopic, is removably fixed on the upper edge of the compacting member 8, this extension carrying the eye on which the hook of the cable 18 hangs.

Dans le mode de réalisation de la figure 3, l'axe 6 est porté par une noix 22 dans le taraudage de laquelle est vissée une tige filetée 23 qui est montée à rotation par ses deux extrémités lisses dans deux portées 24 soudées sur la tôle de fond 3. Une extrémité de la tige filetée 23 sort à l'extérieur de la benne par un palier 25 et est solidaire à la rotation par un cardan 26 d'un prolongateur 27 qui peut être raccordé à la prise de force du tracteur. L'organe de compactage 8 dont le basculement pour assurer le compactage peut être commandé d'une façon quelconque,peut, de plus, subir une translation dans l'un ou l'autre sens selon la flèche A. Des fourreaux 28 qui coulissent sur les portées 24 protègent la vis filetée 23 contre l'encrassement par la matière compactée. Le déplacement de l'organe de compactage selon la flèche A peut assurer une premièere compression de la matière et rapprocher également l'organe de compactage de la paroi 4 pour assurer un compactage homogène.In the embodiment of Figure 3, the axis 6 is carried by a nut 22 in the thread of which is screwed a threaded rod 23 which is rotatably mounted by its two smooth ends in two bearing surfaces 24 welded to the sheet metal bottom 3. One end of the threaded rod 23 exits outside the bucket by a bearing 25 and is integral with the rotation by a universal joint 26 of an extension 27 which can be connected to the power take-off of the tractor. The compacting member 8 whose tilting to ensure compaction can be com mandé in any way, can, moreover, undergo a translation in one or the other direction according to arrow A. Sleeves 28 which slide on the surfaces 24 protect the threaded screw 23 against fouling by the material compacted. The displacement of the compacting member according to arrow A can ensure a first compression of the material and also bring the compacting member closer to the wall 4 to ensure a homogeneous compaction.

Dans le mode de réalisation de la figure 4, l'organe de compactage 8 est de largeur réduite par rapport à la largeur totale de la benne et il est fixé sur l'axe 6 limité à la partie centrale de la benne par un palier en double cône 29 qui permet d'incliner latéralement l'organe de compactage pour venir compacter alternativement la masse de matériau se trouvant dans les parties droite et gauche ou dans la partie centrale de la benne. Pour assurer un compactage de la matière se trouvant dans la partie basse voisine de la paroi 1, une plaque 30 est articulée en 31 dans l'axe de l'organe 8 et elle vient pendre librement le long de la paroi 1 pour balayer ce volume de matière.In the embodiment of Figure 4, the compacting member 8 is of reduced width compared to the total width of the bucket and it is fixed on the axis 6 limited to the central part of the bucket by a bearing in double cone 29 which allows the compacting member to be tilted laterally so as to alternately compact the mass of material located in the right and left parts or in the central part of the bucket. To ensure compaction of the material located in the lower part adjacent to the wall 1, a plate 30 is articulated at 31 in the axis of the member 8 and it hangs freely along the wall 1 to sweep this volume matter.

Dans le mode de réalisation de la figure 5, l'organe de compactage est subdivisé en trois parties 8a, 8b et 8c, ces trois parties étant articulées, à leur base, autour de l'axe 8.In the embodiment of FIG. 5, the compacting member is subdivided into three parts 8a, 8b and 8c, these three parts being articulated, at their base, around the axis 8.

Cette disposition permet, comme le mode de réalisation de la figure 4, de compacter le matériau par tranches longitudinales et donc d'utiliser un appareil moins puissant, et, de plus, d'éviter le contournement de l'organe de compactage par le matériau si la masse d'ensemble présente une certaine capacité de fluage. Si on craint particulièrement un tel contournement, deux éléments en contact tels que 8a, 8b peuvent présenter des flasques latéraux éventuellement à lamelles en éventail qui maintiennent la continuité de la paroi au cours du basculement vers l'avant de l'élément voisin.This arrangement makes it possible, like the embodiment of FIG. 4, to compact the material in longitudinal sections and therefore to use a less powerful device, and, moreover, to avoid the circumvention of the compacting member by the material. if the overall mass has a certain creep capacity. If there is a particular fear of such a bypass, two elements in contact such as 8a, 8b may have lateral flanges possibly with fan-shaped lamellae which maintain the continuity of the wall during the tilting of the neighboring element towards the front.

A la figure 6, on a représenté une variante de réalisation de l'organe de compactage 8 de la figure 4 dans laquelle l'organe de compactage est amovible. L'axe 6 est monté coulissant dans des portées 31 soudées sur le fond 3 et dans un tube 32 qui relie une des portées 31 à la paroi 1 adjacente. L'axe 6 comporte des moyens 33 de blocage en position. Dans ce mode de réalisation, l'organe de raccordement 12 est solidarisé avec la partie 11 de l'organe de compactage par un axe non représenté qui peut de plus s'engager dans l'une d'une série de portées 34 pour faire varier le bras de levier et la course. Ceci permet de retirer l'organe de raccordement 12 après le compactage pour qu'il ne gène pas l'opération de chargement de la benne. Il est également possible de réaliser la partie 11 de l'organe de compactage 8 sous forme télescopique.In Figure 6, there is shown an alternative embodiment of the compacting member 8 of Figure 4 in which the compacting member is removable. The axis 6 is slidably mounted in bearing surfaces 31 welded to the bottom 3 and in a tube 32 which connects one of the bearing surfaces 31 to the adjacent wall 1. The axis 6 includes means 33 for locking in position. In this embodiment, the connecting member 12 is secured to the part 11 of the compacting member by an axis not shown which can further engage in one of a series of spans 34 to vary the lever arm and the stroke. This makes it possible to remove the connecting member 12 after compaction so that it does not interfere with the operation of loading the bucket. It is also possible to produce the part 11 of the compacting member 8 in telescopic form.

Selon une variante de réalisation les portées 31 sont soudées sur un faux-châssis constitué, par exemple, par des poutres telles que 2' et des entretoises non représentées qui s'adapte dans la benne, l'axe 6 passant seulement entre lesdites portées. Avec cette variante de réalisation la totalité du dispositif de compactage est indépendante de la benne.According to an alternative embodiment, the bearing surfaces 31 are welded to a subframe constituted, for example, by beams such as 2 'and not shown spacers which fits in the bucket, the axis 6 passing only between said bearing surfaces. With this variant embodiment, the entire compacting device is independent of the bucket.

Dans le mode de réalisation représenté aux figures 7 et 8 un bras 35 est monté à rotation autour d'un axe 36 au sommet de la paroi 1 de la benne située derrière le bras de compactage. A son extrémité opposée ledit bras porte un galet 37 qui vient en appui sur la face arrière du bras 11.. La rotation du bras 35 autour de son axe 36 exerce une poussée par l'intermédiaire du galet 37, poussée qui va en croissant jusqu'à ce que la ligne joignant l'axe 36 à l'axe du galet 37 soit perpendiculaire à la face arrière du bras 11. Le couple assurant la rotation du bras peut être exercé avec une fourche d'élévateur 38 engagée dans un logement 39 prévu à cet effet dans le bras ou au moyen d'un vérin 40 agissant entre un axe 41 porté par la benne 1 et un axe 42 solidaire du bras.In the embodiment shown in Figures 7 and 8 an arm 35 is rotatably mounted about an axis 36 at the top of the wall 1 of the bucket located behind the compacting arm. At its opposite end, said arm carries a roller 37 which comes to bear on the rear face of the arm 11. The rotation of the arm 35 about its axis 36 exerts a thrust via the roller 37, thrust which increases until 'so that the line joining the axis 36 to the axis of the roller 37 is perpendicular to the rear face of the arm 11. The torque ensuring the rotation of the arm can be exerted with an elevator fork 38 engaged in a housing 39 provided for this purpose in the arm or by means of a jack 40 acting between an axis 41 carried by the bucket 1 and an axis 42 secured to the arm.

Un tel moyen d'accouplement entre l'organe de traction et/ou de poussée et le bras de compactage s'est avéré efficace pour éviter le point mort au début du mouvement de compactage mais sa course est trop limitée.Such a coupling means between the traction member and / or thrust and the compacting arm has proven effective in avoiding neutral at the start of the compacting movement, but its stroke is too limited.

Dans le dispositif illustré à titre d'exemple dans les figures 9 à 13, les mêmes éléments que dans les figures 7 et 8 sont désignés par les mêmes références. Pour prolonger l'action du bras à galet 35 on a équipé le bras d'un dispositif de démultiplication à bielles commandé par la rotation du bras 35.In the device illustrated by way of example in FIGS. 9 to 13, the same elements as in FIGS. 7 and 8 are designated by the same references. To prolong the action of the roller arm 35, the arm has been equipped with a linkage reduction device controlled by the rotation of the arm 35.

Les bielles du dispositif de démultiplication peuvent être jumelées. Ledit dispositif comporte une première bielle 43 articulée en 44 sur un point fixe solidaire d'une paroi de la benne 1, l'axe 44 étant voisin de l'axe 36. A son autre extrémité la bielle 43 est articulée en 45 sur une deuxième bielle 46 qui est elle-même articulée en 47 sur une troisième bielle 48 articulée en 49 sur le bras de compactage. Autour de l'axe 45 est articulée une troisième bielle 50 articulée à son autre extrémité en 51 sur une bielle 52 articulée en 53 sur le bras à galet 35. L'axe 42 d'articulation du vérin fait saillie sur les deux faces latérales du bras 35 comme représenté dans la figure 8 et il vient au cours de la rotation du bras 35 prendre appui contre les bielles jumelées 50 ou 52 pour entraîner le système de bielles comme cela sera décrit ci-après.The connecting rods of the reduction gear can be combined. Said device comprises a first connecting rod 43 articulated at 44 on a fixed point secured to a wall of the bucket 1, the axis 44 being close to the axis 36. At its other end the connecting rod 43 is articulated at 45 on a second connecting rod 46 which is itself articulated at 47 on a third connecting rod 48 articulated at 49 on the compacting arm. Around the axis 45 is articulated a third connecting rod 50 articulated at its other end at 51 on a connecting rod 52 articulated at 53 on the roller arm 35. The axis 42 of articulation of the jack projects on the two lateral faces of the arm 35 as shown in Figure 8 and it comes during the rotation of the arm 35 to bear against the twin connecting rods 50 or 52 to drive the connecting rod system as will be described below.

Le dispositif est complété par une butée 54 montée sur le bras de compactage 11 et qui limite la possibilité de rotation de la bielle 48 sous une poussée exercée par la bielle 46. Un galet 55 est également monté sur les bras de compactage et il limite la rotation de la bielle 46 autour de l'axe 47 lorsque la bielle 48 est en appui sur la butée 54. La référence 56 désigne une butée prévue sur le bras 11 pour limiter la rotation de la bielle 48 dans le sens l'écartant de la butée 54 pour éviter que les deux articulations formant genouillères 45 et 47 s'inversent en empêchant le retour du dispositif à sa position de départ sous l'action du vérin 40. Un dispositif d'accrochage porté par le bras 35 et non représenté, solidarise, pendant le début de la course de retour, le bras 35 avec la bielle 52 pour assurer le retour au point de départ du dispositif de démultiplication à bielles.The device is completed by a stop 54 mounted on the compacting arm 11 and which limits the possibility of rotation of the connecting rod 48 under a thrust exerted by the connecting rod 46. A roller 55 is also mounted on the compacting arms and it limits the rotation of the connecting rod 46 about the axis 47 when the connecting rod 48 is in abutment on the stop 54. The reference 56 designates a stop provided on the arm 11 to limit the rotation of the connecting rod 48 in the direction away from the stop 54 to prevent the two joints forming knee pads 45 and 47 are reversed, preventing the device from returning to its starting position under the action of the jack 40. A hooking device carried by the arm 35 and not shown, is secured during the start of the return stroke, the arm 35 with the connecting rod 52 to ensure the return to the starting point of the connecting rod reduction device.

Dans la figure 9 et pour plus de clarté le dispositif a été représenté alors que le vérin 40 a déjà commencé sa course de contraction, le bras de compactage ayant déjà légèrement tourné dans le sens de la flèche F sous la poussée du galet 37. L'axe 42 se trouve à l'intérieur du triangle circonscrit par les bielles 50 et 52 et le bras avance sous la seule poussée du galet 37. Après la rotation du bras 35 d'un angle qui dépend des longueurs relatives des bielles, l'axe 42 vient en appui contre les bielles 50 et 52 ou dans l'angle entre ces biellettes et va, à partir de ce moment, commander, par l'intermédiaire de la bielle 50, la rotation de la bielle 43 et des bielles 46 et 48. Ce mode d'accouplement entre l'axe 42et le système de bielles constitue un dispositif à course morte qui permet de faire agir successivement le bras à galet alors que la force de poussée des genouillères dont les bielles forment entre elles des angles aigus, est faible, puis le dispositif à genouillères pour prolonger l'action de compactage avec des angles de genouillères beaucoup plus ouverts.In FIG. 9 and for greater clarity, the device has been shown while the jack 40 has already started its contraction stroke, the compacting arm having already turned slightly in the direction of the arrow F under the thrust of the roller 37. L the axis 42 is inside the triangle circumscribed by the connecting rods 50 and 52 and the arm advances under the sole thrust of the roller 37. After the rotation of the arm 35 by an angle which depends on the relative lengths of the connecting rods, the axis 42 abuts against the connecting rods 50 and 52 or in the angle between these connecting rods and will, from this moment, control, via the connecting rod 50, the rotation of the connecting rod 43 and connecting rods 46 and 48. This mode of coupling between the axis 42 and the system of connecting rods constitutes a dead-stroke device which makes it possible to cause the roller arm to act successively while the thrust force of the kneepads whose connecting rods form acute angles between them, is weak then the knee lifter for prol onger the compaction action with much more open toggle angles.

Dans la figure 10 on a représenté le dispositif pendant ce deuxième stade, la bielle 48 étant poussée en appui contre la butée 54 et le galet 37 étant écarté de la face arrière du bras de compactage. Au cours de cette phase du mouvement et du fait de l'ouverture progressive des angles des genouillères 45 et 47, la bielle 46 qui tourne autour de l'axe 47 vient en appui sur le galet 55 comme illustré à la figure 11. A partir de ce moment la descente de l'axe 45 sous la traction du vérin 40 transmise par la bielle 50 fait pivoter la bielle 46 autour du galet 55 en faisant simultanément tourner la bielle 48 autour de l'axe 49 en l'écartant de la butée 54 pour la rapprocher de la butée 56. A ce moment les bielles 43, 46 et 48 sont presque alignées et la force de traction exercée au point 45 est multipliée dans une proportion extrêmement importante.In Figure 10 there is shown the device during this second stage, the rod 48 being pushed into abutment against the stop 54 and the roller 37 being spaced from the rear face of the compacting arm. During this phase of the movement and due to the progressive opening of the angles of the knee pads 45 and 47, the connecting rod 46 which rotates around the axis 47 comes to bear on the roller 55 as illustrated in FIG. 11. From from this moment the descent of the axis 45 under the traction of the jack 40 transmitted by the connecting rod 50 rotates the connecting rod 46 around the roller 55 while simultaneously rotating the rod 48 around the axis 49 away from the stop 54 to bring it closer to the stop 56. At this time the rods 43, 46 and 48 are almost aligned and the tensile force exerted at point 45 is multiplied in an extremely large proportion.

Les positions lla, llb, llc, lld du bras de compactage 11 aux stades correspondant aux figures 9 à 12 sont représentées dans la figure 13.The positions 11a, 11b, 11c, 11d of the compacting arm 11 at the stages corresponding to FIGS. 9 to 12 are shown in FIG. 13.

Dans les figures 14 à 17 on a représenté un dispositif analogue adapté au chargement et au compactage dans une benne parallélipipédique 57. Dans ces figures les mêmes références sont utilisées pour désigner les éléments équivalents de ceux décrits avec référence aux figures 9 à 12. Dans ce mode de réalisation, le bras à galet 35-37 n'est pas utilisé et le vérin 40 agit directement sur l'articulation 45. On retrouve donc les trois bielles 43, 46 et 48 articulées en 44, 45, 47 et 49 et les butées 54, 56 et le galet 55 portés par le bras de compactage 11 comme dans le mode de réalisation précédent. Le bras de compactage et son dispositif de commande sont toutefois montés dans un caisson 58 articulé par un emboîtement à demi-chape et axe 59 à la partie inférieure d'un cadre de porte arrière 60, l'axe 59 servant également d'axe d'articulation pour le bras de compactage 11.In Figures 14 to 17 there is shown a similar device suitable for loading and compacting in a parallelepipedal bucket 57. In these figures the same references are used to designate the equivalent elements of those described with reference to Figures 9 to 12. In this embodiment, the roller arm 35-37 is not used and the jack 40 acts directly on the articulation 45. There are therefore the three connecting rods 43, 46 and 48 articulated at 44, 45, 47 and 49 and the stops 54, 56 and the roller 55 carried by the compacting arm 11 as in the previous embodiment. The compacting arm and its control device are however mounted in a box 58 articulated by a half-yoke interlock and axis 59 at the lower part of a rear door frame 60, the axis 59 also serving as axis d hinge for the compacting arm 11.

Le caisson 58 peut être relevé par basculement autour de l'axe 59 sous l'action d'un vérin 61 pour venir en face de l'ouverture arrière de la benne (Fig. 15). Dans cette position le vérin 40 peut être mis en action pour, dans un premier temps, faire passer les produits entassés dans le caisson, au stade préliminaire illustré dans la figure 14, dans la benne 57, puis compacter les produits se trouvant dans cette benne 57, comme illustré à la figure 16. Le cadre de porte arrière 60 est de préférence articulé à son extrémité supérieure autour d'un axe 62 et un vérin 63 permet de relever le cadre de porte arrière 60 par rotation autour de l'axe 62, comme illustré à la figure 17 pour permettre de vidanger la benne 57 en l'inclinant par basculement dans le sens indiqué par la flèche V dans la figure 17.The box 58 can be raised by tilting around the axis 59 under the action of a jack 61 to come in front of the rear opening of the bucket (Fig. 15). In this position, the jack 40 can be actuated to, firstly, pass the products piled up in the box, at the preliminary stage illustrated in FIG. 14, in the bucket 57, then compact the products being in this bucket. 57, as illustrated in FIG. 16. The rear door frame 60 is preferably articulated at its upper end about an axis 62 and a jack 63 makes it possible to raise the rear door frame 60 by rotation about the axis 62, as illustrated in FIG. 17 to allow the bucket 57 to be emptied by tilting it by tilting in the direction indicated by the arrow V in FIG. 17.

Le dispositif représenté aux figures 14 à 17 peut être facilement rendu amovible de la benne par retrait d'un nombre limité d'axes d'articulation ou par dégagement de la chape de l'axe 59.The device shown in FIGS. 14 to 17 can be easily made removable from the bucket by removing a limited number of articulation axes or by releasing the clevis from the axis 59.
