Sweeping method comprising the combined use of a mechanical brush (9) and a container (10) at the front of a motor vehicle, in which the front edge (26) of the forwardly open container (10) is arranged almost against the ground to be swept, the ground is swept by driving the brush in rotation so that the swept material is projected rearwardly through the container opening and the material in the container is removed by raising the container (10) and inclining its opening downwardly and in which the brush is moved freely and automatically away from the container so as to clear its opening when an obstacle is encountered and the brush is automatically returned to its initial position when the obstacle disappears, characterized in that, during sweeping, the brush (9) is freely and automatically lowered under the effect of gravity towards the ground adjacent to the opening of the container (10) and in that, in the removal position, when the opening of the container is inclined downwardly well above the ground, the brush is freely and automatically moved away under the effect of gravity from the front edge of the container so as to clear the container opening and the brush (9) is possibly used to help remove the granular material from the container.

Description

La présente invention est relative à un procédé de brossage comprenant le support conjoint d'une brosse mécanique et d'un récipient à l'avant d'un véhicule moteur, l'agencement du récipient ouvert vers l'avant presque contre un sol à brosser, le brossage du sol par entraînement en rotation de la brosse de manière à projeter la matière brossée à travers l'ouverture du récipient, et l'évacuation de la matière contenue dans le récipient par élévation du récipient et inclinaison de son ouverture vers le bas.The present invention relates to a brushing method comprising the joint support of a mechanical brush and a container at the front of a motor vehicle, the arrangement of the container open towards the front almost against a floor to be brushed. , brushing the floor by driving the brush in rotation so as to project the brushed material through the container opening, and removing the material contained in the container by raising the container and tilting its opening downwards .

L'invention concerne également un dispositif de brossage, comprenant un véhicule moteur pourvu d'un organe porte-outil, qui peut être levé et baissé par rapport au véhicule moteur, ainsi qu'un outil de brossage, qui est accrochable à l'organe porte-outil et qui comporte au moins une brosse mécanique et un récipient supportant la ou les brosses et présentant une ouverture par laquelle la matière à brosser est projetée au cours du brossage et est évacuée lors du vidage du récipient, le récipient susdit étant relié à l'organe porte-outil en étant capable de pivoter par rapport à lui autour d'un axe horizontal sous l'action d'un moyen d'entraînement en pivotement commandé depuis le véhicule moteur.The invention also relates to a brushing device, comprising a motor vehicle provided with a tool-carrying member, which can be raised and lowered relative to the motor vehicle, as well as a brushing tool, which is hookable to the member. tool holder and which comprises at least one mechanical brush and a container supporting the brush or brushes and having an opening through which the material to be brushed is projected during brushing and is discharged during emptying of the container, the aforesaid container being connected to the tool-holder member being able to pivot relative to it about a horizontal axis under the action of a pivoting drive means controlled from the motor vehicle.

L'invention peut être appliquée notamment au cours de travaux de pavage, de travaux de balayage de rues ou de sols d'usines, etc....The invention can be applied in particular during paving works, street sweeping works or factory floors, etc.

On connaît déjà un dispositif et un procédé de brossage tels que décrits ci-dessus (voir US-A-2.697.846). Ce dispositif présente l'inconvénient que, dans n'importe quelle position donnée du récipient en forme de godet utilisé, tout écartement entre la brosse et le godet pour libérer réellement l'ouverture de celui-ci doit résulter nécessairement d'une commande depuis le véhicule moteur. Cela limite énormément la mise en oeuvre de ce dispositif de brossage trop rigide. En effet il se coince inévitablement dès que la brosse rencontre un obstacle, par exemple un objet à brosser de grande dimension, telle qu'une brique ou un bloc en bois ou en ciment, un tas de matière granuleuse, etc.....A brushing device and method are already known as described above (see US-A-2,697,846). This device has the disadvantage that, in any given position of the container in the form of a cup used, any spacing between the brush and the cup to actually release the opening of the latter must necessarily result from a command from the motor vehicle. This greatly limits the use of this brushing device too rigid. In fact, it inevitably gets stuck as soon as the brush encounters an obstacle, for example a large object to be brushed, such as a brick or a wooden or cement block, a pile of grainy material, etc.

On connaît aussi un dispositif et un procédé de brossage, (voir notamment les brevets BE-A-899.230 et BE-A-902.003), où un véhicule tracteur est pourvu d'un outil servant uniquement au brossage de pavements sur lesquels du sable vient d'être répandu et tassé. Cet outil, peu maniable, est formé d'un récipient de récolte et d'une brosse rotative agencés de manière fixe l'un par rapport à l'autre; ces deux éléments ne peuvent présenter que deux positions, une position de brossage et une position suspendue dans laquelle le récipient peut être vidé. Le guidage de l'outil au cours du brossage ne peut s'effectuer que par traction. Enfin, des particules de matière brossées vers le haut ou latéralement peuvent ne pas parvenir dans le récipient et même salir le véhicule tracteur ou atteindre son pilote (voir également le brevet US-A-3.444.583).There is also known a brushing device and method, (see in particular the patents BE-A-899,230 and BE-A-902,003), where a tractor vehicle is provided with a tool used only for brushing pavements on which sand comes to be spread and packed. This tool, which is not very handy, is made up of a collection container and a rotating brush arranged in a fixed manner with respect to each other; these two elements can only have two positions, a brushing position and a hanging position in which the container can be emptied. Guiding the tool during brushing can only be done by pulling. Finally, particles of material brushed upwards or laterally may not reach the container and even soil the towing vehicle or reach its driver (see also patent US-A-3,444,583).

On connaît également depuis longtemps des véhicules déplaçables comprenant un porte-outil sur lequel peut s'accrocher un godet sans dent. A l'aide de ce godet, accroché sur le porte-outil de manière à pouvoir pivoter par rapport à ce dernier autour d'un axe horizontal, il est possible de prélever de la matière granuleuse, par exemple du sable, à partir d'un tas et de l'épandre sur le sol en inclinant le godet vers le bas et vers l'avant de façon que seul son bord avant se trouve à peu de distance du sol et que le contenu du godet s'écoule petit à petit sur le sol au fur et à mesure du recul du véhicule. Il est même possible de se servir du bord avant du godet pour essayer d'égaliser une couche de sable préalablement répandue (voir également à ce propos les brevets belges précités). Toutefois, il n'est pas possible d'obtenir ainsi une égalisation parfaitement uniforme d'une mince couche de matière granuleuse à la surface d'un sol et, le moyen utilisé étant fort puissant, il peut être dangereux de l'appliquer pour enfoncer par exemple du sable entre des pavés qui viennent d'être posés. Enfin, à l'aide du bord avant d'un tel godet, il est connu de racler le sol préalablement au brossage, cette opération étant indispensable lorsque de la boue ou du sable humide recouvre la surface à nettoyer.Movable vehicles have also been known for a long time, comprising a tool holder on which a toothless bucket can be hung. Using this bucket, hung on the tool holder so as to be able to pivot relative to the latter around a horizontal axis, it is possible to take granular material, for example sand, from a pile and spread it on the ground by tilting the bucket down and forward so that only its front edge is a short distance from the ground and the contents of the bucket gradually flows out the ground as the vehicle reverses. It is even possible to use the front edge of the bucket to try to equalize a layer of sand previously spread (see also the Belgian patents mentioned above). However, it is not possible to obtain a perfectly uniform equalization of a thin layer of granular material on the surface of a soil and, the means used being very powerful, it can be dangerous to apply it to drive in for example sand between pavers that have just been laid. Finally, using the front edge of such a bucket, it is known to scrape the ground before brushing, this operation being essential when mud or wet sand covers the surface to be cleaned.

La présente invention a pour but de mettre au point un dispositif et un procédé de brossage permettant d'effectuer non seulement le brossage d'une surface, même couverte de résidus de grande dimension, et le vidage du récipient de récolte, mais aussi le remplissage du récipient à partir d'un tas de matière granuleuse et l'épandage uniforme de cette dernière sur un sol ainsi qu'éventuellement son enfoncement entre des pavés qui viennent d'être posés, tout en évitant simultanément les inconvénients précités. Elle doit également pouvoir permettre un raclage du sol simultanément au brossage de ce dernier. De même on doit pouvoir l'utiliser comme chasse-neige.The object of the present invention is to develop a brushing device and method making it possible to carry out not only the brushing of a surface, even covered with large residues, and the emptying of the harvest container, but also the filling. of the container from a heap of granular material and the uniform spreading of the latter on a ground as well as possibly its sinking between pavers which have just been laid, while simultaneously avoiding the aforementioned drawbacks. It must also be able to allow scraping of the soil simultaneously with brushing of the latter. Likewise, it must be able to be used as a snow plow.

On a résolu ces problèmes, suivant l'invention, par la mise en oeuvre d'un dispositif, tel que décrit au début, dans lequel la ou les brosses mécaniques sont supportées par le récipient de manière librement déplaçable à l'écart du récipient depuis une position de brossage où la brosse est adjacente à l'ouverture du récipient, de façon à libérer automatiquement cette ouverture dans la position de vidage du récipient ou lors de la rencontre d'un obstacle par la ou les brosses.These problems have been solved, according to the invention, by the use of a device, as described at the start, in which the mechanical brush or brushes are supported by the container in a freely movable manner away from the container from a brushing position where the brush is adjacent to the opening of the container, so as to automatically release this opening in the emptying position of the container or when an obstacle is encountered by the brush or brushes.

Suivant une forme de réalisation de l'invention, la ou ou les brosses mécaniques sont capables de pivoter par rapport au récipient autour d'un axe de pivotement horizontal.According to one embodiment of the invention, the mechanical brush or brushes are capable of pivoting relative to the container about a horizontal pivot axis.

Suivant une forme particulière de réalisation de l'invention, le centre de gravité de la ou des brosses mécaniques est localisé de façon qu'elles soient automatiquement dans une position rabattue en direction de l'ouverture du récipient lors du brossage et en position écartée de cette ouverture lors du vidage du récipient.According to a particular embodiment of the invention, the center of gravity of the mechanical brush or brushes is located so that they are automatically in a folded position in the direction of the opening of the container during brushing and in the position separated from this opening when emptying the container.

Suivant une forme avantageuse de réalisation de l'invention, le récipient est un godet présentant deux parois latérales, une paroi arrière et une paroi de fond et la brosse mécanique est une brosse rotative qui peut être amenée à tourner autour d'un axe de rotation horizontal par un moyen d'entraînement en rotation commandé depuis le véhicule moteur.According to an advantageous embodiment of the invention, the container is a cup having two side walls, a rear wall and a bottom wall and the mechanical brush is a rotary brush which can be made to rotate about an axis of rotation. horizontal by a rotary drive means controlled from the motor vehicle.

On a également prévu, suivant l'invention, un procédé de brossage, tel que décrit au début, qui comprend, au cours du brossage, un déplacement libre et automatique de la brosse à l'écart du récipient de façon à libérer son ouverture, lors de la rencontre d'un obstacle, et un retour libre et automatique de la brosse à sa position initiale dès la disparition de l'obstacle, ainsi que, dans la position d'évacuation, un écartement libre et automatique de la brosse de façon à libérer l'ouverture du récipient, et éventuellement la mise en oeuvre de la brosse pour aider à l'évacuation de la matière granuleuse hors du récipient.There is also provided, according to the invention, a brushing process, as described at the beginning, which comprises, during brushing, a free and automatic movement of the brush away from the container. so as to free its opening, when an obstacle is encountered, and a free and automatic return of the brush to its initial position as soon as the obstacle disappears, as well as, in the evacuation position, a free separation and automatic brushing to release the opening of the container, and possibly the use of the brush to assist in the evacuation of the granular material from the container.

Le dispositif de brossage suivant l'invention, dans l'exemple de réalisation illustré sur les dessins, comprend un véhicule moteur l, sous la forme d'une chargeuse hydraulique qui est pourvue d'un organe porte-outil formé de deux bras coudés 2 reliés chacun, par une de leurs extrémités, à l'arrière du véhicule moteur 1, de façon à pouvoir pivoter par rapport à celui-ci autour d'axes 3. Des vérins hydrauliques 4, articulés d'une part sur le véhicule moteur 1 et d'autre part approximativement au milieu des bras 2, permettent de lever et de descendre ceux-ci par une commande provenant du véhicule 1.The brushing device according to the invention, in the embodiment illustrated in the drawings, comprises a motor vehicle 1, in the form of a hydraulic loader which is provided with a tool-carrying member formed by two bent arms 2 each connected by one of their ends to the rear of the motor vehicle 1, so as to be able to pivot relative to the latter about axes 3. Hydraulic cylinders 4, articulated on the one hand on the motor vehicle 1 and other leaves approximately in the middle of the arms 2, allow them to be raised and lowered by a command from the vehicle 1.

Entre les extrémités des bras 2, opposées à celles reliées au véhicule 1 et orientées vers le bas en position basse à la suite du coude des bras, on a prévu l'articulation d'un organe de verrouillage rapide 5 pour l'outil à utiliser.Le bas de cet organe de verrouillage 5 est articulé entre les bras 2 de façon qu'il puisse pivoter autour d'un axe horizontal 6 par rapport à l'organe porte-outil 2. Un vérin hydraulique 7 est également raccordé de manière articulée entre d'une part le coude de chaque bras 2 et d'autre part l'extrémité de l'organe de verrouillage rapide 5 opposée à son articulation sur les bras 2. Le ou les vérins hydrauliques 7 commandés depuis le véhicule moteur 1 permettent ainsi un pivotement limité de l'organe de verrouillage 5 et un maintien ferme de ce dernier dans n'importe quelle position intermédiaire à ses deux fins de course.Between the ends of the arms 2, opposite those connected to the vehicle 1 and oriented downwards in the low position following the elbow of the arms, provision has been made for the articulation of a quick locking member 5 for the tool to be used. .The bottom of this locking member 5 is articulated between the arms 2 so that it can pivot around a horizontal axis 6 relative to the tool-carrying member 2. A hydraulic cylinder 7 is also articulated in an articulated manner between on the one hand the elbow of each arm 2 and on the other hand the end of the quick locking member 5 opposite to its articulation on the arms 2. The hydraulic jack or jacks 7 controlled from the motor vehicle 1 thus allow a limited pivoting of the locking member 5 and a firm hold of the latter in any intermediate position at its two limit switches.

Selon l'exemple de réalisation illustré, le dispositif de brossage suivant l'invention comprend aussi un outil de brossage désigné par la référence générale 8. Cet outil de brossage comporte une brosse mécanique 9, et un récipient de récolte de la matière brossée, ici sous la forme d'un godet sans dent 10. Le godet comporte d'une manière courante deux parois latérales 11, 12, une paroi arrière 13 et une paroi de fond 14. Suivant l'invention l'outil de brossage 8 est relié à l'organe porte-outil 2 par le godet 10 qui est capable de pivoter par rapport à lui autour d'un axe horizontal sous l'action d'un moyen d'entraînement en pivotement commandé depuis le véhicule moteur. Dans l'exemple de réalisation illustré le godet 10 est relié aux bras 2 du porte-outil par l'intermédiaire de l'organe de verrouillage rapide 5 et il peut être entraîné en pivotement autour de l'axe 6, situé approximativement au bas de sa paroi arrière 13, par les vérins hydrauliques 7. La fixation aisément détachable entre le godet 10 et l'organe de verrouillage rapide 5 est connue en soi et elle n'est donc pas décrite de manière plus détaillée.According to the illustrated embodiment, the brushing device according to the invention also comprises a brushing tool designated by the general reference 8. This brushing tool comprises a mechanical brush 9, and a container for collecting the brushed material, here in the form of a bucket without teeth 10. The bucket commonly comprises two side walls 11, 12, a rear wall 13 and a bottom wall 14. According to the invention the brushing tool 8 is connected to the tool-carrying member 2 by the bucket 10 which is capable of pivoting with respect to it about a horizontal axis under the action of a pivoting drive means controlled from the motor vehicle. In the illustrated embodiment, the bucket 10 is connected to the arms 2 of the tool holder by means of the quick locking member 5 and it can be pivoted around the axis 6, located approximately at the bottom of its rear wall 13, by the hydraulic cylinders 7. The easily detachable attachment between the bucket 10 and the rapid locking member 5 is known per se and is therefore not described in more detail.

Suivant l'invention, la brosse mécanique, ici sous la forme d'une brosse rotative 9, est supportée par le godet 10 de manière à pouvoir pivoter librement par rapport à lui autour d'un axe horizontal. Dans l'exemple illustré, le godet est pourvu le long de chacun de ses coins arrière de deux ferrures 15 qui font saillie au-dessus du godet. Des bras de support 16 de la brosse rotative sont supportés à une de leurs extrémités par des axes 17 horizontaux, coaxiaux, qui chacun sont agencés entre deux des ferrures 15 précitées. Les bras de support 16, dans la position basse du godet 10, s'étendent par-dessus ce dernier et ils suportent entre eux à leur extrémité libre les tourillons d'un axe de rotation horizontal 18 qui peut être entraîné en rotation de manière commandée depuis le véhicule moteur et qui entraîne alors à son tour la brosse 9 en rotation.According to the invention, the mechanical brush, here in the form of a rotary brush 9, is supported by the bucket 10 so as to be able to pivot freely relative to it about a horizontal axis. In the example illustrated, the bucket is provided along each of its rear corners with two fittings 15 which project above the bucket. Support arms 16 of the rotary brush are supported at one of their ends by horizontal axes 17, coaxial, which each are arranged between two of the above-mentioned fittings 15. The support arms 16, in the low position of the bucket 10, extend over the latter and they support between them at their free end the pins of a horizontal axis of rotation 18 which can be driven in rotation in a controlled manner from the motor vehicle and which then in turn drives the brush 9 in rotation.

Dans l'exemple de réalisation illustré, les bras de support 16 de la brosse sont mutuellement reliés de façon à former un couvercle 38 par-dessus le godet. Ils s'étendent également vers le bas sous la forme de flasques latéraux 19 et 20, disposés dans un plan légèrement décalé vers l'intérieur par rapport au plan des bras 16 et ainsi capables de pénétrer à l'intérieur du godet. Les bras de support 16, le couvercle 38 et les flasques latéraux 19 et 20 forment ainsi un capot qui empêche la projection de la matière brossée vers le haut ou latéralement par rapport au godet 10.In the exemplary embodiment illustrated, the support arms 16 of the brush are mutually connected so as to form a cover 38 over the cup. They also extend downwards in the form of lateral flanges 19 and 20, arranged in a plane slightly offset inwards relative to the plane of the arms 16 and thus capable of penetrating inside the bucket. The support arms 16, the cover 38 and the lateral flanges 19 and 20 thus form a cover which prevents the brushed material from being projected upwards or laterally relative to the bucket 10.

Le moyen d'entraînement en rotation de la brosse 9 est, ainsi qu'il est représenté de manière schématique sur la figure 1, un moteur hydraulique 21 fixé de manière abritée sous le couvercle 38. Son arbre de sortie 22 traverse l'un des bras de support 16 et entraîne en rotation un pignon denté 23, qui par l'intermédiaire d'une chaîne 24 peut entraîner en rotation un pignon denté 25, fixé sur l'extrémité externe d'un des tourillons de l'arbre de rotation 18 de la brosse 9. Cette transmission est abritée sous un recouvrement approprié quelconque 37, avantageusement détachable du bras 16 qui le supporte. Le moteur hydraulique 21 est raccordé à une prise hydraulique auxiliaire 27 supportée par l'un des bras 2 du porte-outil, par l'intermédiaire de tuyaux flexibles 28. Ceux-ci sont, par mesure de sécurité, appliqués contre la paroi latérale 12 du godet 10 à l'aide d'une fixation appropriée quelconque, par exemple une attache 29 montée sur un aimant permanent.The means for driving the brush 9 in rotation is, as shown diagrammatically in FIG. 1, a hydraulic motor 21 fixed in a sheltered manner under the cover 38. Its output shaft 22 passes through one of the support arm 16 and rotates a toothed pinion 23, which via a chain 24 can rotate a toothed pinion 25, fixed on the outer end of one of the pins of the rotation shaft 18 of the brush 9. This transmission is housed under any suitable covering 37, advantageously detachable from the arm 16 which supports it. The hydraulic motor 21 is connected to an auxiliary hydraulic outlet 27 supported by one of the arms 2 of the tool holder, by means of flexible hoses 28. These are, for safety reasons, applied against the side wall 12 of the bucket 10 using any suitable fixing, for example a clip 29 mounted on a permanent magnet.

Enfin, les parois latérales externes des bras de support 16 de la brosse 9 sont pourvues de pièces taraudées 31 dans lesquelles sont passées deux tiges filetées 32 munies de manivelles 33. Par vissage on peut régler la longueur de tige dépassant vers le bas les pièces taraudées 31 et ainsi limiter le mouvement de pivotement vers le bas de la brosse, car les tiges filetées 32 viennent heurter des butées 34 agencées à l'extérieur sur les parois latérales 11 et 12 du godet 10.Finally, the external side walls of the support arms 16 of the brush 9 are provided with threaded parts 31 in which are passed two threaded rods 32 provided with cranks 33. By screwing one can adjust the length of rod exceeding down the threaded parts 31 and thus limit the pivoting movement down of the brush, because the threaded rods 32 come up against stops 34 arranged outside on the side walls 11 and 12 of the bucket 10.

Dans la position de brossage représentée sur les figures 1 et 2, les bras 2 du porte-outil sont en position basse et la paroi de fond 14 du godet 10 est disposée presque à plat sur le sol, par retrait de la tige des vérins 7 à l'intérieur de leur cylindre. L'axe de pivotement 6 du godet est approximativement au bas de sa paroi arrière 13 et les axes coaxiaux de pivotement 17 de la brosse sont situés au-dessus de cette paroi arrière 13 approximativement dans le prolongement du plan de cette dernière, tandis que les bras de support 16 s'étendent vers l'avant et vers le bas. Dans cette position, le centre de gravité de la brosse 9 et de ses moyens de support et d'entraînement en rotation, c'est-à-dire les bras 16, le couvercle 38 et les flasques latéraux 19 et 20, ainsi que le moteur 21 et les moyens de transmission 22 à 25 et 18, est localisé de telle façon que la brosse subit une force vers le bas qui l'entraîne en pivotement autour des axes 17 dans le sens contraire aux aiguilles d'une montre sur la figure 2, c'est-à-dire en direction à la fois du sol et du bord avant 26 du godet. Donc, dans la position de brossage, la brosse rotative 9 est automatiquement rabattue en direction de l'ouverture du godet, en étant entraînée en rotation dans le sens indiqué par" la flèche SI sur la figure 2. Elle projette ainsi la matière granuleuse ou les saletés se trouvant sur le sol dans l'ouverture du godet 10 Si l'objet à brosser est de grande dimension, la brosse grimpe par-dessus pour permettre son avalerrent par le godet. Le bord avant 26 du godet peut être, comme illustré sur la figure 2, appliqué contre le sol, et dans ce cas il racle, simultanément au brossage, la boue ou le sable humide adhérent fortement au sol, par exemple la boue amenée par les pneus de camion. Un tel raclage simultané au brossage ne peut être obtenu à l'aide de beaucoup de brosses traditionnelles. Pour un tel raclage, le bord avant 26 est en acier anti-usure lorsqu'il s'agit de racler du béton ou de l'asphalte et il est avantageusement muni d'une lèvre en nylon ou matière analogue pour racler une surface de pavés structurée, pour ne pas blesser les pavés. Un ajustement de la hauteur de brosse peut toutefois être obtenu par le réglage, mentionné précédemment, de la longueur des tiges filetées 32 à l'aide des manivelles 33. Ainsi, comme illustré sur la figure 6, la brosse 9 en position rabattue n'entre pas en contact avec le sol et il est possible d'effectuer une opération de raclage, sans brossage simultané.In the brushing position shown in Figures 1 and 2, the arms 2 of the tool holder are in the low position and the bottom wall 14 of the bucket 10 is disposed almost flat on the ground, by removing the rod from the jacks 7 inside their cylinder. The pivot axis 6 of the bucket is approximately at the bottom of its rear wall 13 and the coaxial pivot axes 17 of the brush are located above this rear wall 13 approximately in the extension of the plane of the latter, while the support arms 16 extend forward and downward. In this position, the center of gravity of the brush 9 and of its support and rotary drive means, that is to say the arms 16, the cover 38 and the lateral flanges 19 and 20, as well as the motor 21 and the transmission means 22 to 25 and 18, is located in such a way that the brush undergoes a downward force which causes it to pivot around the axes 17 in the anti-clockwise direction in the figure 2, that is to say in the direction of both the ground and the front edge 26 of the bucket. Therefore, in the brushing position, the rotary brush 9 is automatically folded down in the direction of the opening of the bucket, while being driven in rotation in the direction indicated by "the arrow SI in FIG. 2. It thus projects the granular material or dirt on the floor in the opening of the bucket 10 If the object to be brushed is large, the brush climbs over it to allow it to be swallowed up by the bucket. The front edge 26 of the bucket can be, as illustrated in FIG. 2, applied against the ground, and in this case it scrapes, simultaneously with brushing, the mud or wet sand adhering strongly to the ground, for example the mud brought by the truck tires. Such a scraping simultaneous with brushing does not can be obtained using many traditional brushes. For such scraping, the front edge 26 is made of wear-resistant steel when it comes to scraping concrete or asphalt and it is advantageously provided with a nylon or material lip analogous for scraping a structured paving surface, so as not to injure the paving stones. An adjustment of the brush height can however be obtained by the adjustment, mentioned above, of the length of the threaded rods 32 using the cranks 33. Thus, as illustrated in FIG. 6, the brush 9 in the folded position does not does not come into contact with the ground and it is possible to perform a scraping operation, without simultaneous brushing.

Après remplissage du godet, celui-ci peut être soulevé par élévation des bras 2 à la suite d'une extension des vérins 4. Ensuite, comme illustré sur la figure 5, les vérins 7 peuvent être amenés en position d'extension, ce qui amène la paroi arrière 13 du godet 10 approximativement à l'horizontale, les axes coaxiaux de pivotement 17 de la brosse 9 étant alors situés à l'avant du godet. Dans cette position, le centre de gravité de la brosse et de ses moyens de support et d'entraînement en rotation est localisé de telle façon que la brosse subit une force qui l'entraîne légèrement en pivotement autour des axes 17 dans le sens des aiguilles d'une montre sur la figure 5, c'est-à-dire que la brosse 9 est légèrement écartée vers l'avant par rapport au bord avant 26 du godet 10. La brosse libère ainsi automatiquement l'ouverture du godet, alors dirigée vers le bas et permet l'évacuation du contenu du godet. En faisant tourner la brosse 9 dans le sens S2 de la flèche représentée sur la figure 5, sens qui est inverse à celui du brossage, la brosse sert même simultanément de moyen de vidage auxiliaire du godet 10.After filling the bucket, it can be lifted by raising the arms 2 following an extension of the jacks 4. Then, as illustrated in FIG. 5, the jacks 7 can be brought into the extended position, which brings the rear wall 13 of the bucket 10 approximately horizontally, the coaxial pivot axes 17 of the brush 9 then being located at the front of the bucket. In this position, the center of gravity of the brush and of its support and rotary drive means is located in such a way that the brush undergoes a force which causes it to pivot slightly around the axes 17 in the direction of the needles. of a watch in FIG. 5, that is to say that the brush 9 is slightly moved forward with respect to the front edge 26 of the bucket 10. The brush thus automatically releases the opening of the bucket, then directed down and allows the evacuation of the contents of the bucket. By rotating the brush 9 in the direction S2 of the arrow shown in FIG. 5, which direction is opposite to that of brushing, the brush even serves simultaneously as an auxiliary emptying means of the bucket 10.

Ainsi qu'il ressort de la figure 3, le dispositif de brossage suivant l'invention peut simultanément servir de moyen de prélèvement d'une matière granuleuse telle que du sable ou du gravier à partir d'un tas, pour transporter celle-ci à un autre endroit donné. On se sert pour cela du godet 10 qui, d'une manière courante, est enfoncé dans le tas de sable 30 et ensuite relevé vers l'arrière avec son contenu. Cette opération n'est en aucune façon entravée par la présence de la brosse 9 devant l'ouverture du godet 10; au contraire, d'une manière surprenante, celle-ci facilite l'opération et, sert de moyen de remplissage auxiliaire du godet 10. En effet, au moment où le bord avant 26 du godet touche le talus du tas de sable 30, la brosse subit la force de gravité comme au cours du brossage, c'est-à-dire qu'elle est rabattue vers ce bord avant 26. Toutefois, elle rencontre préalablement le talus en question et, comme elle est entraînée en rotation dans le sens S l, cette rotation a pour effet, d'une part, de faire grimper la brosse sur le talus et donc d'ouvrir le godet et, d'autre part, de projeter comme lors du brossage le sable situé sur le tas au-dessus de l'ouverture du godet.As can be seen from FIG. 3, the brushing device according to the invention can simultaneously serve as a means of removing a granular material such as sand or gravel from a pile, to transport it to another given place. We use for this the bucket 10 which, in a current manner, is driven into the pile of sand 30 and then raised backwards with its contents. This operation is in no way hampered by the presence of the brush 9 in front of the opening of the bucket 10; on the contrary, surprisingly, this facilitates the operation and serves as an auxiliary filling means for the bucket 10. In fact, when the front edge 26 of the bucket touches the slope of the sand pile 30, the brush undergoes the force of gravity as during brushing, i.e. that it is folded towards this front edge 26. However, it previously meets the slope in question and, as it is rotated in the direction S l, this rotation has the effect, on the one hand, of causing the brush to climb on the embankment and therefore to open the bucket and, on the other hand, to project as when brushing the sand located on the pile above the opening of the bucket.

Ainsi qu'il ressort de la figure 4, il est possible alors d'épandre le sable du godet sur un sol donné, en reculant le véhicule moteur et en inclinant le godet 10 vers le bas et vers l'avant avec son bord avant 26 adjacent au sol. A l'aide du dispositif suivant l'invention il est alors possible d'égaliser immédiatement à une épaisseur uniforme le sable sortant du godet, en faisant tourner la brosse dans le sens SI. La brosse, par son poids, est rabattue vers le sol et rejette l'excédent de sable vers le godet. On peut ici aussi régler l'épaisseur de la couche de sable que l'on veut obtenir à l'aide des- moyens d'ajustement décrits précédemment 31 à 34. Sur la figure 4, on répand du sable sur un sol 35 formé de pavés qui viennent d'être posés. En plus de son action d'égalisation, la brosse enfonce le sable, qui s'écoule du godet, dans les fentes entre les pavés posés.As can be seen in FIG. 4, it is then possible to spread the sand of the bucket on a given ground, by reversing the motor vehicle and by tilting the bucket 10 down and forward with its front edge 26 adjacent to the ground. Using the device according to the invention, it is then possible to immediately equalize the sand leaving the bucket to a uniform thickness, by rotating the brush in the SI direction. The brush, by its weight, is folded down towards the ground and rejects the excess of sand towards the bucket. It is also possible here to adjust the thickness of the layer of sand which it is desired to obtain using the adjustment means described above 31 to 34. In FIG. 4, sand is spread on a ground 35 formed of pavers that have just been laid. In addition to its equalizing action, the brush pushes the sand, which flows from the bucket, into the slots between the pavers.

Le dispositif maniable suivant l'invention permet donc avantageusement un brossage d'un sol donné et le déversement rapide et aisé du contenu du godet sur un tas ou dans une benne de camion, la brosse aidant même au vidage du godet. Il permet en outre l'épandage uniforme de matière granuleuse sur un sol, en une seule opération, et l'enfoncement éventuel de sable entre des pavés. Le même outil de brossage permet donc de réaliser deux ou même trois opérations du pavage qui jusqu'à présent étaient effectuées par deux outils différents, à savoir l'épandage de sable avant la pose des pavés, l'épandage de sable sur les pavés posés et le brossage du pavement après passage du rouleau ou d'une plaque vibrante. Par soulèvement possible du godet à l'aide du porte-outil il est possible de déverser aisément son contenu au-dessus d'un tas ou dans un camion, ainsi que de prélever du sable ou du gravier à partir d'un tas. La brosse sert de moyen auxiliaire dans chacune de ces opérations et n'entrave en aucune façon ces dernières. Le dispositif suivant l'invention permet aussi, au choix, un raclage du sol simultanément au brossage ou indépendamment du brossage, ou encore un brossage sans raclage. Un coincage du dispositif en cas de rencontre d'obstacle de grande dimension au cours du brossage est exclu. Il doit être entendu que la présente invention n'est en aucune façon limitée aux formes de réalisation décrites ci-dessus et que bien des modifications pourraient y être apportées sans sortir du cadre du présent brevet.The handy device according to the invention therefore advantageously allows brushing of a given soil and quick and easy dumping of the contents of the bucket on a pile or in a truck dump, the brush even helping to empty the bucket. It also allows the uniform spreading of granular material on a soil, in a single operation, and the possible insertion of sand between pavers. The same brushing tool therefore makes it possible to carry out two or even three paving operations which up to now have been carried out by two different tools, namely the spreading of sand before laying the pavers, the spreading of sand on the laid pavers. and brushing the pavement after passing the roller or a vibrating plate. By possible lifting of the bucket using the tool holder it is possible to easily pour its contents over a pile or in a truck, as well as to take sand or gravel from a pile. The brush serves as an auxiliary means in each of these operations and does not in any way hinder them. The device according to the invention also makes it possible, as desired, to scrape the ground simultaneously with brushing or regardless of brushing, or brushing without scraping. A jamming of the device in the event of encountering a large obstacle during brushing is excluded. It should be understood that the present invention is in no way limited to the embodiments described above and that many modifications could be made thereto without departing from the scope of this patent.

On peut envisager des moyens de réglage de hauteur de brossage très différents et notamment l'agencement des butées sur les moyens de support de brosse.It is possible to envisage very different brushing height adjustment means and in particular the arrangement of the stops on the brush support means.

Sur la figure 7, est illustrée une pièce intermédiaire 40, à interposer entre le godet 10 et l'organe de verrouillage rapide 5, lorsque l'on veut utiliser le dispositif de brossage suivant l'invention comme chasse-neige. La pièce intermédiaire 40 comprend une première partie 41 accrochable de la manière habituelle à l'organe de verrouillage 5 et une deuxième partie 42 qui est pourvue de moyens de verrouillage usuels, non représentés, semblables à ceux dont est pourvu l'organe de verrouillage 5. Sur ces moyens de verrouillage le godet 10 peut être fixé. Les deux parties 41, 42 de la pièce intermédiaire 40 sont réunies l'une à l'autre, d'un côté du véhicule, par des charnières 43 et de l'autre par des moyens extensibles, notamment des bras télescopiques 44, 45. Ceux-ci peuvent être fixés dans plusieurs positions d'extension données par des moyens usuels, tels que des perforations 46 et des goupilles 47. Dans les positions d'extension des bras télescopiques 44, 45, la partie 42 est écartée, du côté du véhicule opposé aux charnières 43, de la partie 41, et il en est de même pour le godet 10 et pour la brosse 9. Ceux-ci sont ainsi orientés en oblique par rapport à l'axe de déplacement du véhicule et la brosse 9, entraînée dans le sens de rotation S2, peut chasser, par exemple la neige, sur le côté. A nouveau la rencontre d'un obstacle impossible à chasser par la seule brosse ne provoque pas le coincement du dispositif. La brosse grimpe par-dessus l'obstacle.In FIG. 7, an intermediate piece 40 is illustrated, to be interposed between the bucket 10 and the rapid locking member 5, when it is desired to use the brushing device according to the invention as a snow plow. The intermediate piece 40 comprises a first part 41 which can be hooked in the usual way to the locking member 5 and a second part 42 which is provided with conventional locking means, not shown, similar to those with which the locking member 5 is provided. On these locking means the bucket 10 can be fixed. The two parts 41, 42 of the intermediate piece 40 are joined to one another, on one side of the vehicle, by hinges 43 and on the other by extendable means, in particular telescopic arms 44, 45. These can be fixed in several extension positions given by usual means, such as perforations 46 and pins 47. In the extension positions of the telescopic arms 44, 45, the part 42 is spread apart, on the side of the vehicle opposite to the hinges 43, of the part 41, and it is the same for the bucket 10 and for the brush 9. These are thus oriented obliquely with respect to the axis of movement of the vehicle and the brush 9, driven in the direction of rotation S2, can drive, for example snow, on the side. Again, meeting an obstacle that cannot be removed by the brush alone does not cause the device to jam. The brush climbs over the obstacle.
