Des engins de terrassement, tels que les pelles hydrauliques, sont de façon fréquente utilisés pour des opérations très diverses en plus de l'opération de terrassement pro­prement dite. De telles opérations necessitent en général le remplacement du godet de l'engin par un outillage approprié.Earth-moving machinery, such as hydraulic shovels, is frequently used for a wide variety of operations in addition to the earth-moving operation itself. Such operations generally require the replacement of the bucket of the machine by an appropriate tool.

A titre d'exemple, on emploie pour terrasser un godet dit "rétro" que l'on remplace pour compacter par un outil hydraulique de compactage. Les seules opérations de chan­gement représentent une perte de temps et une diminution de rentabilité considérables.By way of example, a so-called "retro" bucket is used to excavate, which is replaced to compact by a hydraulic compacting tool. The only change operations represent a considerable loss of time and decrease in profitability.

La présente invention a pour but premier de remédier aux inconvénients ci-dessus et, en particulier, de faciliter les opérations de démontage ou de remontage nécessitées par le changement de nature du travail à accomplir.The primary object of the present invention is to remedy the above drawbacks and, in particular, to facilitate the disassembly or reassembly operations required by the change in the nature of the work to be performed.

Si l'interchangeabilité des outils n'est pas instantanée, ces outils ne sont alors pas utilisés, le boulonnage étant trop lent.If the interchangeability of the tools is not instantaneous, then these tools are not used, the bolting being too slow.

Par ailleurs, le document FR - A - 2 602 256 montre divers usages que l'on peut faire d'un vibreur sous pelle.Furthermore, the document FR - A - 2 602 256 shows various uses that can be made of a vibrator under an excavator.

La présente invention se propose donc d'assurer les conditions optimales pour qu'un con­ducteur de pelle puisse, sans changer de place dans sa cabine, adapter sur le bloc vi­breur monté sous sa pelle un grand nombre d'outillages de type quelconque en créant ainsi un dispositif remplissant les fonctions de réception et de blocage de l'outillage en même temps que de blocage omnidirectionnel du vibreur et, accessoirement, une fonction de rotation mécanique et hydraulique de l'ensemble du dispositif.The present invention therefore proposes to ensure the optimal conditions so that a shovel operator can, without changing place in his cabin, adapt on the vibrator block mounted under his shovel a large number of tools of any type thereby creating a device fulfilling the functions of receiving and blocking the tooling at the same time as omnidirectional blocking of the vibrator and, incidentally, a function of mechanical and hydraulic rotation of the entire device.

Conformément à l'invention, le dispositif d'interchangeabilité instantanée d'outillage pour engins de terrassement, selon la revendication 1 du brevet principal, est caracté­risé en ce qu'il comprend un bloc vibreur relié aux bras du porteur par une plaque et comportant des amortisseurs de liaison avec ladite plaque, des moyens montés entre le bloc vibreur et la plaque et commandés à distance pour assurer un blocage momentané et contrôlé du jeu vertical des amortisseurs, des moyens étant prévus de manière corres­pondante respectivement sur le bloc vibreur et sur une plaque à connexion instantanée formant porte-outils pour assurer une liaison amovible entre le bloc vibreur et la pla­que à connexion instantanée qui comprend elle-même des moyens d'encastrement coopérant avec des moyens correspondants prévus sur le bloc vibreur, cette plaque formant partie d'un outil de terrassement tel qu'une pelle hydraulique ou pouvant être relié à un tel outil ou étant outil elle-même.According to the invention, the instantaneous interchangeability tooling device for earth-moving machinery, according to claim 1 of the main patent, is characterized in that it comprises a vibrating block connected to the arms of the carrier by a plate and comprising shock absorbers for connection with said plate, means mounted between the vibrator block and the plate and remotely controlled to ensure momentary and controlled blocking of the vertical play of the shock absorbers, means being provided correspondingly respectively on the vibrator block and on a plate with instant connection forming a tool holder to ensure a removable connection between the vibrator block and the instant connection plate which itself comprises embedding means cooperating with corresponding means provided on the vibrator block, this plate forming part of a earthmoving tool such as a hydraulic shovel or which can be connected to such a tool or being a tool itself.

Conformément à une autre caractéristique de l'invention, la plaque de liaison aux bras de pelle est elle-même une plaque à connexion instantanée, l'extrémité du bras de pelle étant relié à un chassis support et des moyens étant prévus sur ce chassis support pour assurer une liaison amovible avec cette plaque à connexion instantanée. Ces moyens pré­vus seront identiques à ceux installés sur le vibreur.According to another characteristic of the invention, the plate connecting to the shovel arms is itself a plate with instant connection, the end of the shovel arm being connected to a support frame and means being provided on this support frame. to ensure a removable connection with this instant connection plate. These planned means will be identical to those installed on the vibrator.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

Un vérin hydraulique (6) prend en outre appui, d'un manière connue en soi, d'une part, en (7) sur le bras de pelle (2) et, d'autre part, par l'intermédiaire d'une bielle (8) sur un point d'articulation (9) d'une seconde patte (4a) du dispositif d'interchangea­bilité (3). Il est ainsi possible de contrôler, par l'intermédiaire du vérin (6) et de la centrale hydraulique de l'engin de terrassement, la rotation du godet (1) par rapport au bras (2).A hydraulic cylinder (6) further bears, in a manner known per se, on the one hand, at (7) on the shovel arm (2) and, on the other hand, by means of a connecting rod (8) on a point of articulation (9) of a second tab (4a) of the interchangeability device (3). It is thus possible to control, through the jack (6) and the hydraulic unit of the earth-moving machine, the rotation of the bucket (1) relative to the arm (2).

Comme on le voit également de manière plus détaillée à la fig. 2, qui représente l'en­semble du dispositif d'interchangeabilité (3) en position de montage, ce dernier comprend un bloc vibreur (10) de type connu en soi et comportant par exemple un vibreur à masselotte excentré, un vibreur électromagnétique ou de préférence un vibreur (11) de type hydrauli­que relié à la centrale de l'engin de terrassement par des conduites souples (12) - fig.1-As can also be seen in more detail in FIG. 2, which represents the whole of the interchangeability device (3) in the mounting position, the latter comprises a vibrator block (10) of a type known per se and comprising, for example, an eccentric counterweight vibrator, an electromagnetic vibrator or preferably a vibrator (11) of hydraulic type connected to the central of the earthmoving machine by flexible pipes (12) - fig.1-

A la fig. 2, le bloc vibreur (10) est terminé de chaque côté par des ailes latérales (13) formant récepteur pour la fixation d'amortisseurs (14) à des arceaux (15) destinés à être reliés en (16a), (16b) à une plaque (17) de connexion à la pelle de la fig. 1 et qui pré­sente à cet effet les pattes de liaison (4) et (4a) mentionnées plus haut.In fig. 2, the vibrator block (10) is terminated on each side by lateral wings (13) forming a receiver for fixing shock absorbers (14) to arches (15) intended to be connected at (16a), (16b) to a plate (17) for connection to the shovel of fig. 1 and which has for this purpose the connecting lugs (4) and (4a) mentioned above.

Conformément à l'invention, les amortisseurs (14) qui sont connus dans la technique sous l'appellation de silent-blocs sont réalisés par exemple en caoutchouc armé et servent à ce que les vibrations provoquées par le bloc vibreur (10) ne soient pas transmises au bras de pelle (2) de la fig. 1.According to the invention, the shock absorbers (14) which are known in the art under the name of silent-blocks are made for example of reinforced rubber and are used so that the vibrations caused by the vibrating block (10) are not transmitted to the shovel arm (2) of fig. 1.

Cependant, lorsque l'engin de terrassement est prévu avec un godet servant à l'arrache­ment et non pas au compactage comme cela est prévu dans FR - A - 2 602 256, il est alors avantageux de pouvoir relier mécaniquement et de manière contrôlée le godet (1) à la plaque de connexion (17) en commandant un blocage omnidirectionnel momentané du jeu des amortisseurs (14).However, when the earthmoving machine is provided with a bucket used for lifting and not for compaction as provided in FR - A - 2 602 256, it is then advantageous to be able to mechanically and in a controlled manner connect the bucket (1) to the connection plate (17) by commanding a momentary omnidirectional blocking of the play of the shock absorbers (14).

A cet effet, chacun des arceaux (15) solidaire de la plaque de connexion (17) présente un bras vertical intermédiaire (18) de transmission mécanique sur lequel sont montés des vérins hydrauliques (19) destinés à être commandés à distance par l'intermédiaire de la central hydraulique de l'engin de terrassement et à venir en butée contre les ailes (13) du corps vibrant (10), en annulant ainsi et de manière mécanique le jeu omni­directionnel des amortisseurs (14). De manière à permettre un contrôle du blocage des amortisseurs, on peut également, conformément à l'invention, prévoir une disposition de freinage electro-magnétique montée entre le bras (18) et l'aile (13) et commandée à partir d'une centrale électrique à la disposition du conducteur de l'engin de terrassement.For this purpose, each of the arches (15) integral with the connection plate (17) has an intermediate vertical arm (18) of mechanical transmission on which are mounted hydraulic cylinders (19) intended to be controlled remotely by the intermediary of the hydraulic central of the earth-moving machine and coming into abutment against the wings (13) of the vibrating body (10), thereby canceling and mechanically the omnidirectional play of the shock absorbers (14). In order to allow a control of the blocking of the shock absorbers, it is also possible, in accordance with the invention, to provide an electro-magnetic braking arrangement mounted between the arm (18) and the wing (13) and controlled from a power plant available to the driver of the earth-moving machine.

En outre, et comme on le voit bien à la fig. 2, le dispositif d'interchangeabilité (3) conforme à l'invention comporte de plus une plaque (20) à connexion instantanée pour tout outil, tel que le godet (1) fixé sous elle par tout moyen approprié, et présente des oreilles réceptrices (21) à perforations coniques (22) destinées à recevoir des axes de blocage (23) commandés par des vérins hydrauliques (24) traversant les ailes (13) du bloc vibreur (10) et alimentés par la centrale hydraulique de l'engin de terrassement.In addition, and as can be seen in FIG. 2, the interchangeability device (3) according to the invention further comprises a plate (20) with instant connection for any tool, such as the cup (1) fixed under it by any appropriate means, and has receiving ears (21) with conical perforations (22) intended to receive locking pins (23) controlled by hydraulic cylinders (24) passing through the wings (13) of the vibrating block (10) and supplied by the hydraulic unit of the machine earthworks.

De même que ci-dessus pour le blocage momentané du jeu des amortisseurs, on peut ici prévoir une disposition électromagnétique ainsi que toute autre disposition pour comman­der la rentrée des axes de blocage (23) dans les perforations coniques (22) et, respecti­vement, leur sortie, le but étant, dans tous les cas, de réaliser une interchangeabilité de la plaque à connexion instantanée (20) avec le bloc vibreur (10).As above for the momentary blocking of the play of the shock absorbers, it is possible here to provide an electromagnetic arrangement as well as any other arrangement for controlling the retraction of the locking pins (23) in the conical perforations (22) and, respectively, their output, the aim being, in all cases, to achieve interchangeability of the instant connection plate (20) with the vibrator block (10).

En outre, et comme on peut encore le remarquer à la fig. 2, lors du montage de la pla­que porte-outils (20), en même temps que les axes (23) sont bloqués dans les perforations coniques (22), la base (25) des ailes (13) du bloc vibreur (10) est bloquée contre la partie supérieure (26) de la plaque.In addition, and as can still be seen in FIG. 2, during assembly of the tool plate (20), at the same time as the pins (23) are locked in the conical perforations (22), the base (25) of the wings (13) of the vibrator block (10) is locked against the upper part (26) of the plate.

De plus, les oreilles réceptrices (21) présentent une forme trapézoïdale particulière leur permettant d'assurer le guidage aisé recherché de la plaque de connexion (20) lors de la prise d'un outil tel que le godet (1). Ainsi, un plaque horizontale (27), prévue dans la partie centrale du bloc vibreur (10) entre les ailes (13) de ce dernier, se gui­de le long de plans inclinés (28) bordant les oreilles réceptrices (21), en même temps que les ailes (13) se guident le long du plan incliné d'équerres (29) perpendiculaires au plan des oreilles réceptrices (21).In addition, the receiving ears (21) have a particular trapezoidal shape allowing them to ensure the desired easy guidance of the connection plate (20) when taking a tool such as the bucket (1). Thus, a horizontal plate (27), provided in the central part of the vibrator block (10) between the wings (13) of the latter, is guided along inclined planes (28) bordering the receiving ears (21), at the same while the wings (13) are guided along the inclined plane of brackets (29) perpendicular to the plane of the receiving ears (21).

Lorsque le bloc vibreur (10) est arrivé au bout des différents guides ci-dessus, il sera automatiquement positionné entre des blocages (30) et (30b) des oreilles réceptrices (21), en assurant un encastrement absolu de la plaque sur le bloc vibreur. Il ne reste plus qu'à verrouiller la liaison par les vérins hydrauliques (24) dont les axes de blocage (23) pénètrent dans les perforations coniques (22).When the vibrating block (10) has reached the end of the various guides above, it will be automatically positioned between blockings (30) and (30b) of the receiving ears (21), ensuring absolute embedding of the plate on the block vibrator. It only remains to lock the connection by the hydraulic cylinders (24) whose locking pins (23) penetrate into the conical perforations (22).

Comme on l'a vu plus haut, le dispositif d'interchangeabilité conforme à l'invention permet un blocage total de la plaque de connexion (20) sur le bloc vibreur (10) avec un rattrapage permanent des jeux de la fixation du corps vibreur (10) avec la plaque de con­nexion (20), ce qui est rendu obligatoire du fait de la vibration qui ne tolère aucun jeu à aucun moment. Ainsi, le montage adopté se compose des quatre vérins (24) terminés par les axes de blocage en cône (23) et placés à l'avant et à l'arrière du bloc vibreur (10). Ces vérins ont pour objet de venir loger leur axe de blocage (23) dans les perfora­tions coniques (22) correspondantes des oreilles réceptrices (22) de la plaque à connexion instantanée (20) et qui sont de préférence, montées latéralement comme représentées au dessin.As seen above, the interchangeability device according to the invention allows total blocking of the connection plate (20) on the vibrator block (10) with permanent take-up of the games in the fixing of the vibrator body (10) with the connection plate (20), which is made compulsory due to the vibration which tolerates no play at any time. Thus, the assembly adopted consists of the four jacks (24) terminated by the cone locking pins (23) and placed at the front and at the rear of the vibrator block (10). The purpose of these jacks is to accommodate their locking pin (23) in the corresponding conical perforations (22) of the receiving ears (22) of the instant connection plate (20) and which are preferably mounted laterally as shown in the drawing. .

En outre, la mise en place des vérins, la longueur des ailes (13) du bloc vibreur (10) par rapport à la plaque à connexion instantanée (20) formant porte-outils ainsi que le positionnement de la plaque horizontale de guidage (27) formée entre les ailes (13) ré­ ceptrices sont aclculés de telle manière que lors du blocage par les vérins hydrauliques (24), le porte-outils est totalement bloqué contre la base du bloc vibreur (10). De cette manière et comme on l'a vu plus haut, avec seulement quatre vérins (24) on assure douze points de blocage ce qui permet un encastrement absolu du porte-outils sur le bloc vi­breur.In addition, the positioning of the jacks, the length of the wings (13) of the vibrator block (10) relative to the instant connection plate (20) forming a tool holder as well as the positioning of the horizontal guide plate (27 ) formed between the wings (13) re ceptrices are tilted in such a way that during blocking by the hydraulic cylinders (24), the tool holder is completely locked against the base of the vibrator block (10). In this way and as we have seen above, with only four cylinders (24), twelve locking points are ensured, which allows absolute embedding of the tool holder on the vibrating block.

La fig. 3 montre la plaque de connexion (20) des figures précédentes munie d'un disposi­tif de rotation. A titre d'exemple, un axe vertical (31) très résistant sera fixé par tous moyens appropriés sur l'arceau (15). On prévoira, à cet effet, des perçages et file­tages (32). La plaque (20) sera munie de préférence d'un logement rond permettant la mi­se en place d'éléments autolubrifiants (33) en bronze ou autre matière facilitant la ro­tation. Un dispositif de blocage approprié (34) permettra d'assurer un positionnement de la plaque (20) par rapport à la plaque (17) reliant les arceaux (15). Le montage final du dispositif de rotation sera assuré par une plaque (35) bloquée par des boulons (36).Fig. 3 shows the connection plate (20) of the previous figures provided with a rotation device. By way of example, a very resistant vertical axis (31) will be fixed by any appropriate means to the hoop (15). For this purpose, holes and threads (32) will be provided. The plate (20) will preferably be provided with a round housing allowing the installation of self-lubricating elements (33) in bronze or other material facilitating rotation. A suitable locking device (34) will ensure positioning of the plate (20) relative to the plate (17) connecting the arches (15). The final assembly of the rotation device will be ensured by a plate (35) blocked by bolts (36).

On a représenté à la fig. 4, un certain nombre d'outils au nombre desquels on trouve un compacteur latéral de gros tuyaux, un couteau à asphalte, une plaque de compactage à pied de mouton, de tels outils pouvant être montés sur la plaque de connexion (20) à la place du godet (1) des fig. 1 et 2. De même, la plaque (20) peut elle-même faire partie d'un tel outil (voir également la fig. 9).There is shown in FIG. 4, a number of tools including a lateral compactor for large pipes, an asphalt cutter, a sheep-foot compaction plate, such tools that can be mounted on the connection plate (20) to the place of the bucket (1) of fig. 1 and 2. Likewise, the plate (20) can itself be part of such a tool (see also fig. 9).

La fig. 5 montre un montage particulièrement simple d'une pointerolle sous la plaque de connexion (20). La pointerolle (40) sera guidée dans un alésage de son support (41) selon la longueur de course préchoisie. Une butée (42) est aménagée sous la plaque de connexion (20) pour que l'arrière de la pointerolle (40) soit frappé par la butée lorsque la pelle de l'engin de terrassement pousse sur un obstacle. On obtient ainsi un marteau brise-­roche. D'autres outils tels que bêche pourront être utilisés.Fig. 5 shows a particularly simple assembly of a chuck under the connection plate (20). The chisel (40) will be guided in a bore in its support (41) according to the pre-selected stroke length. A stop (42) is arranged under the connection plate (20) so that the rear of the chisel (40) is struck by the stop when the shovel of the earth-moving machine pushes on an obstacle. This produces a breaker hammer. Other tools such as spade may be used.

Sur les chantiers d'assainissement à deux pelles, l'une de ces pelles sert au terrasse­ment tandis que l'autre est équipée d'un bloc vibreur avec ses différents outils inter­changeables. Sur les chantiers à une seule pelle, la pelle sera munie d'un équipement et le bloc de connexion rapide (20), fixé hydrauliquement sur le corps vibreur (10), peut lui-même être muni de dispositifs commandés hydrauliquement. Il en est ainsi des pinces à serrage hydraulique de palplanches. Dans d'autres corps de métier, par exemple chez les poseurs de poteaux télégraphiques, on utilisera un tube soudé sous le bloc de connexion (20). Ce tube sera de formes et dimensions appropriées au trou à réaliser pour la pose des poteaux. Sur une autre plaque de connexion, on pourra monter une pince commandée hydrauliquement de manière connue en soi et, lors de la pose des poteaux, le trou sera fait en associant le tube à la vibration du bloc vibreur (10). La manoeuvre et la mise en place du poteau se feront soit par une pince montée sous le bloc vibreur dont on aura bloqué l'élasticité par le blocage mécanique prévu ci-dessus, soit, après dépose du bloc vibreur, par une reprise instantanée directement sur le bras de la pince de manutention montée sur la plaque de connexion.On sanitation sites with two shovels, one of these shovels is used for earthworks while the other is equipped with a vibrating block with its various interchangeable tools. On sites with a single shovel, the shovel will be fitted with equipment and the quick connection block (20), hydraulically fixed to the vibrating body (10), may itself be fitted with hydraulically controlled devices. This is the case with hydraulic sheet pile clamps. In other trades, for example at telegraph pole installers, a tube welded under the connection block (20) will be used. This tube will be of shapes and dimensions appropriate to the hole to be made for the installation of the posts. On another connection plate, it is possible to mount a hydraulically controlled clamp in a manner known per se and, during the installation of the posts, the hole will be made by associating the tube with the vibration of the vibrating block (10). The process and the installation of the post will be done either by a clamp mounted under the vibrating block whose elasticity will have been blocked by the mechanical blocking provided above, or, after removing the vibrating block, by an instantaneous recovery directly on the arm of the handling clamp mounted on the connection plate.

La description précédente concernait de manière plus particulière l'interchangeabilité d'outillage sous des vibreurs montés sur des pelles hydrauliques ou autres engins de terrassement.The previous description more specifically concerned the interchangeability of tools under vibrators mounted on hydraulic shovels or other earth-moving machinery.

Dans ce qui suit, les moyens de connexion sont fortement améliorés et trouvent de nou­velles utilisations en ce que le bloc vibreur (10) est lui-même facilement interchan­geable sur la pelle, et que les mêmes outils utilisables sous le bloc vibreur pourront l'être de même manière directement sous le bras de pelle.In what follows, the connection means are greatly improved and find new uses in that the vibrating block (10) is itself easily interchangeable on the shovel, and that the same tools that can be used under the vibrating block may be similarly directly under the shovel arm.

Dans la technique antérieure, on connaît déjà des dispositifs de connexion rapide entre pelle et godet mais ceux-ci sont d'emploi limité.In the prior art, devices for quick connection between shovel and bucket are already known, but these are of limited use.

Ce qui suit permet ainsi de rationaliser et d'harmoniser techniquement les moyens d'attache sur le bloc vibreur et les moyens d'attache sous pelle pour recevoir les mêmes outils.The following thus makes it possible to rationalize and harmonize technically the means of attachment to the vibrating block and the means of attachment under the shovel to receive the same tools.

Aux fig. 6 et 7, on a représenté un nouvel élément se composant d'un chassis support (50) dont la partie supérieure reçoit les blocs récepteurs (51) d'un bras de pelle (52) semblable au bras de pelle (2) de la fig. 1, les blocs récepteurs (51) jouant alors le rôle des pattes (4) et (4a) de la fig. 2. Le chassis support (50) en forme de U est pré­vu pour le maintien de vérins hydrauliques (53) dont les axes de blocage coniques (54) traversent des perforations correspondantes (55) formées dans des oreilles (56) d'une plaque de connexion (57) semblable à la plaque de connexion instantanée (20) des figures précédentes. La distance entre les axes de blocage coniques (54) et le bord des ailes du chassis support en U (50) correspond à ce qui a été décrit précédemment relativement au bloc vibreur (10), le chassis support (50) jouant, en ce qui concerne la liaison à la plaque (57), le même rôle que le bloc vibreur (10) vis-à-vis de la plaque (20), et des dispositions semblables à celles décrites précédemment peuvent être prévues sur ce chas­sis support (50) afin de coopérer avec des éléments correspondants prévus sur la plaque de connexion (56). On remarque, par exemple, qu'à la fig. 7, une plaque horizontale (58) du chassis support (50) vient se guider entre les blocages (59a) de la plaque de connexion (57) pour contribuer à un encastrement de chassis support (50) sur la plaque de connexion instantanée (57) de la même façon qu'à la fig. 2 pour la plaque de guidage (27) et les blocages (30a), (30b).In fig. 6 and 7, there is shown a new element consisting of a support frame (50) the upper part of which receives the receiving blocks (51) of a shovel arm (52) similar to the shovel arm (2) of the fig. 1, the receiver blocks (51) then playing the role of the tabs (4) and (4a) of FIG. 2. The U-shaped support frame (50) is designed to hold hydraulic cylinders (53) whose conical locking pins (54) pass through corresponding perforations (55) formed in the ears (56) of a plate connection (57) similar to the instant connection plate (20) of the previous figures. The distance between the conical locking pins (54) and the edge of the wings of the U-shaped support frame (50) corresponds to what has been described previously with respect to the vibrating block (10), the support frame (50) playing, in this which relates to the connection to the plate (57), the same role as the vibrator block (10) with respect to the plate (20), and arrangements similar to those described above can be provided on this support frame (50 ) in order to cooperate with corresponding elements provided on the connection plate (56). Note, for example, that in fig. 7, a horizontal plate (58) of the support frame (50) comes to guide itself between the blockings (59a) of the connection plate (57) to contribute to an embedding of support frame (50) on the instant connection plate (57 ) in the same way as in fig. 2 for the guide plate (27) and the locks (30a), (30b).

De la sorte, on pourra monter des outils sur des plaques de connexion qui seront reliées soit directement au bras de pelle soit par l'intermédiaire du bloc vibreur (10). On voit ainsi que, dans le premier cas, la plaque à connexion (57) joue le rôle de la plaque (17) de la fig. 2.In this way, tools can be mounted on connection plates which will be connected either directly to the shovel arm or via the vibrating block (10). It can thus be seen that, in the first case, the connection plate (57) plays the role of the plate (17) of FIG. 2.

La figure 8 montre une légère variante dans laquelle les ailes du U du chassis support ont été aménagées en fonction d'un outil différent à monter sans que ceci n'altère tou­tefois les fonctions de l'ensemble du dispositif d'interchangeabilité conforme à la pré­sente invention.FIG. 8 shows a slight variant in which the wings of the U of the support chassis have been arranged as a function of a different tool to be mounted without this, however, altering the functions of the entire interchangeability device in accordance with this. invention.

Comme on peut le voir à la fig. 9, dans le cas de godets de terrassement, par exemple, on aménagera, dans la plaque de connexion au godet, des ouvertures coniques semblables aux ouvertures coniques (22) des plaques de connexion (20) et (56) des figures précé­dentes. On aménagera de même les points d'appui de manière identique en positionnement et appui de manière telle que l'on puisse alors monter le godet soit directement sous la pelle, soit sous le bloc vibreur.As can be seen in fig. 9, in the case of earthmoving buckets, for example, there will be arranged, in the connection plate to the bucket, conical openings similar to the conical openings (22) of the connection plates (20) and (56) of the preceding figures. Likewise, the support points will be arranged identically in positioning and support in such a way that the bucket can then be mounted either directly under the shovel, or under the vibrating block.

L'alimentation hydraulique pourra se faire à partir du circuit hydraulique du porteur. L'alimentation pourra aussi se faire par un circuit hydraulique spécifique ou par les vérins de godet munis de dérivation commandés par électrovanne.The hydraulic supply can be done from the hydraulic circuit of the carrier. The supply can also be done by a specific hydraulic circuit or by the bucket cylinders provided with bypass controlled by solenoid valve.

Les fig. 10 et 11 font suite à la fig. 6 où le chassis (50) avec ses moyens (54) peut recevoir de manière fixe à demeure (fig. 10 et 11) ou interchangeable les attaches (51) qui seront fixées sur une plaque (60) se boulonnant sur les dessus du chassis (50).Figs. 10 and 11 follow fig. 6 where the chassis (50) with its means (54) can receive permanently fixed (fig. 10 and 11) or interchangeable the fasteners (51) which will be fixed on a plate (60) bolting on the tops of the chassis (50).

Sur les chantiers d'assainissement ou routiers d'autres travaux sont à réaliser, tels que le fraisage des enrobés. Une manière avantageuse consiste donc à utiliser l'energie vibratoire existant déjà sous la forme du vibreur (10).On sanitation or road construction sites, other work must be carried out, such as the milling of asphalt. An advantageous way therefore consists in using the vibrational energy already existing in the form of the vibrator (10).

Dans les figures 12, 13, 14, des pointes de tungstène (61) seront montées en série de manière appropriée au résultat à obtenir. Ainsi un support longitudinal (62) recevra une rangée de pointes implantées soit selon un plan vertical pour appui vertical ou incliné contraire au sens de l'avancement de l'appareil comme des socs.In Figures 12, 13, 14, tungsten tips (61) will be connected in series as appropriate for the result to be obtained. Thus a longitudinal support (62) will receive a row of points implanted either along a vertical plane for vertical support or inclined opposite to the direction of advancement of the device like plowshares.

Un seul de ces supports (62) monté sur la plaque porte-outils (20) servira à faire du découpage d'enrobés par une saignée étroite et profonde. Plusieurs de ces supports lon­gitudinaux montés côte à côte formeront une surface de fraisage (63) que la pelle ou le porteur pourront faire travailler à leur cadence.Only one of these supports (62) mounted on the tool holder plate (20) will be used to cut asphalt by a narrow and deep groove. Several of these longitudinal supports mounted side by side will form a milling surface (63) that the shovel or the carrier can make work at their rate.

Reste à régler, pour un travail homogène, l'influence de la pression de la pelle sur le vibreur, donc la profondeur d'effet des pointes.It remains to adjust, for a homogeneous work, the influence of the pressure of the shovel on the vibrator, therefore the depth of effect of the tips.

Considérant la partie supérieure du vibreur non vibrante (17), reliée à la pelle par les attaches (51), il convient de fixer par des moyens appropriés (66) sur cette partie un chassis (64) ou tous autres moyens munis de moyens de réglage (65) et prenant appui au sol, par des roulettes (66) par exemple.Considering the upper part of the non-vibrating vibrator (17), connected to the shovel by the fasteners (51), it is advisable to fix by appropriate means (66) on this part a frame (64) or any other means provided with means of adjustment (65) and bearing on the ground, by rollers (66) for example.

La plaque (20) avec ses pointes (61) sera fixée sur le vibreur, lequel par sa rotation, donnera un effet de piochage, soit vertical pour le bouchardage, soit oblique pour le fraisage.The plate (20) with its points (61) will be fixed on the vibrator, which by its rotation, will give a drawing effect, either vertical for bush hammering, or oblique for milling.

Du fait de la hauteur réglable entre la partie non vibrante (17) et la route, de l'élas­ticité des amortisseurs selon l'effet de la vibration, la profondeur de fraisage corres­pondra à la profondeur préréglée par les moyens de réglage.Due to the adjustable height between the non-vibrating part (17) and the road, the elasticity of the shock absorbers according to the effect of the vibration, the milling depth will correspond to the depth preset by the adjustment means.

Quatre moyens de réglage seront installés préférentiellement. Ils permettront de régler l'angle d'attaque du piochage qui se fera par couches longitudinales parallèles en fonc­tion de la profondeur choisie, les premières pointes du système étant les plus hautes donc proches de la surface et les dernières les plus profondes à la profondeur désirée.Four adjustment means will preferably be installed. They will make it possible to adjust the angle of attack of the picking which will be done by parallel longitudinal layers according to the chosen depth, the first points of the system being the highest therefore close to the surface and the last deepest at the desired depth .

La figure 15 montre une vue de dessus dans laquelle les moyens de fixation (66) sont rotatifs pour un montage aisé par le dessus.Figure 15 shows a top view in which the fixing means (66) are rotatable for easy mounting from above.
