Definitions
- the present invention relates to a process for preparing a mixture, in particular for making concrete, mortar, grout or the like intended for masonry.
- the present invention also relates to an apparatus allowing the mixing of several ingredients such as sand, cement, water for example, for the implementation of the method.
- the mixing of such ingredients is traditionally carried out using a concrete mixer.
- the tank generally has a circular outline around an inclined axis of rotation. During the rotation of the tank, the inner peripheral surface of the tank, fitted with drive projections, causes upwards fractions of the mixture which eventually fall back into the mass of ingredients occupying the lower zone of the interior volume of the tank. . This repetitive succession of workouts and fallout of part of the mass produces the desired mixing.
- the tank has an opening directed obliquely upwards making it possible to add this or that ingredient during mixing, for example water.
- the mixture is made, it is emptied into a wheelbarrow then it is transferred from it into a trough where the mason takes the mixture using a trowel.

- the tank can be considerably simplified, it no longer needs internal projections.
- the tank is therefore less expensive, lighter, easier to clean and makes it much easier to draw directly from the prepared mixture, as well as to use - 3 - complete the mixing without significant quantities of mixture remaining trapped in the complex internal shapes of a conventional tank provided with internal blades.
- a removable trough suitable for transporting the mixture to a place of use of the mixture after kneading is used as a tank, for fear of drawing the mixture there with a trowel.
- the gauge can be an article of commerce, therefore at a very low price.
- the user can have two troughs: one is used to make a new quantity of mixture while the other is at the place of use of a quantity previously prepared. Once this quantity has been used up, the user returns to the mixing apparatus with the empty trough and places it on the apparatus after having extracted the full trough which he in turn takes to the place of use.
- a cover provided with a central opening on the trough. Thanks to the oblique axis of rotation at an angle which can be approximately 60 ° with respect to the vertical, it is possible to ensure that the normal filling level of the tank is compatible with an absence of overflow through the orifice central during rotation of the tank.
- the orifice allows an inspection of the mixture during the rotation of the tank and, if necessary, a modification of the composition of the mixture by adding an additional quantity of such or such ingredient.
- the orientation means comprise two support planes of the chassis on the ground, defined by a support zone substantially parallel to the bottom of the trough and an oblique support zone relative to the bottom of the trough It is thus sufficient to switch the entire apparatus to pass from one to the other of the orientations. This considerably reduces the complexity of the device, therefore its weight, its price and its risk of failure.

DESCRIPTION "Procédé pour préparer un mélange et appareil, tel que bétonnière, s'y rapportant" La présente invention concerne un procédé pour préparer un mélange, en particulier pour confectionner un béton, mortier, coulis ou matière analogue destinée à la maçonnerie.DESCRIPTION "Process for preparing a mixture and apparatus, such as a concrete mixer, relating thereto" The present invention relates to a process for preparing a mixture, in particular for making concrete, mortar, grout or the like intended for masonry.
La présente invention concerne également un appareil permettant le malaxage de plusieurs ingrédients tels que sable, ciment, eau par exemple, pour la mise en œuvre du procédé. Le mélange de tels ingrédients est traditionnellement effectué à l'aide d'une bétonnière. Dans les appareils connus, la cuve a en général un contour circulaire autour d'un axe de rotation incliné. Pendant la rotation de la cuve, la surface périphérique intérieure de la cuve, équipée de saillies d'entraînement, entraîne vers le haut des fractions du mélange qui finissent par retomber dans la masse d'ingrédients occupant la zone inférieure du volume intérieur de la cuve. Cette succession répétitive d'entraînements et de retombées d'une partie de la masse produit le malaxage recherché. En général, la cuve présente une ouverture dirigée obliquement vers le haut permettant de rajouter tel ou tel ingrédient en cours de mélange, par exemple de l'eau.The present invention also relates to an apparatus allowing the mixing of several ingredients such as sand, cement, water for example, for the implementation of the method. The mixing of such ingredients is traditionally carried out using a concrete mixer. In known devices, the tank generally has a circular outline around an inclined axis of rotation. During the rotation of the tank, the inner peripheral surface of the tank, fitted with drive projections, causes upwards fractions of the mixture which eventually fall back into the mass of ingredients occupying the lower zone of the interior volume of the tank. . This repetitive succession of workouts and fallout of part of the mass produces the desired mixing. In general, the tank has an opening directed obliquely upwards making it possible to add this or that ingredient during mixing, for example water.
Une fois le mélange confectionné, on le vide dans une brouette puis on le transvase de celle-ci dans une auge où le maçon prélève le mélange à l'aide d'une truelle.Once the mixture is made, it is emptied into a wheelbarrow then it is transferred from it into a trough where the mason takes the mixture using a trowel.
Ce matériel nécessite beaucoup de place pour son rangement. En raison du poids et de l'encombrement, les bétonnières connues sont difficiles à transporter, et cela est même impossible avec une voiture particulière. Les bétonnières connues sont souvent inutilisables pour les travaux situés à l'intérieur des logements d'habitation, notamment en appartement, dans les étages d'un bâtiment ou même plus généralement en ville.This material requires a lot of space for its storage. Due to the weight and size, the known concrete mixers are difficult to transport, and this is even impossible with a private car. Known concrete mixers are often unusable for work located inside residential dwellings, in particular in an apartment, on the floors of a building or even more generally in town.
Les travaux de mise en fonctionnement et de nettoyage de la bétonnière sont fastidieux et il s'y ajoute ceux relatifs au matériel intermédiaire utilisé peur le transport du mélange jusσu'à l'auge. Cela limite l'emploi du matériel connu aux
- 2 - travaux nécessitant des relativement grandes quantités de mélange. En outre, les bétonnières connues et le matériel d'accompagnement nécessaire sont relativement coûteux. Finalement, l'emploi des bétonnières connues est quasiment réservé à des professionnels ou à de gros utilisateurs.The work of putting into operation and cleaning the concrete mixer is tedious and there is added that relating to the intermediate material used for the transport of the mixture to the trough. This limits the use of known material to - 2 - work requiring relatively large quantities of mixture. In addition, the known concrete mixers and the necessary accompanying equipment are relatively expensive. Finally, the use of known concrete mixers is almost reserved for professionals or heavy users.
Cn connaît également α1 après le FR-A-2 637 SIS un appareil multi-fonctions ayant notamment une fonction de malaxage de matières solides. Dans cec appareil complexe, le mélange se fait dans une cuve mtercnangeable permettant le transport du ciment jusqu'au lieu d'utilisation. Mais on n'évite pas le transvasement de la cuve à une auge car les lames de malaxage, mixage, ou coupe qui équipent la cuve rendent dangereuse et peu pratique l'extraction du mélange à l'aide d'une truelle. Cet appareil connu est long et difficile à nettoyer.Cn also knows α 1 after FR-A-2 637 SIS a multi-function device having in particular a mixing function for solid materials. In this complex device, the mixing takes place in an interchangeable tank allowing the transport of the cement to the place of use. But we do not avoid transferring the tank to a trough because the kneading, mixing or cutting blades that equip the tank make it dangerous and impractical to extract the mixture using a trowel. This known device is long and difficult to clean.
Un but de la présente invention est de proposer un procédé et un appareil de mélange permettant de réduire le coût et/ou le poids et/ou l'encombrement du matériel, et/ou d'en simplifier l'utilisation et le nettoyage, ou en tout cas d'apporter une amélioration sur l'un des points précités.An object of the present invention is to provide a mixing method and apparatus making it possible to reduce the cost and / or the weight and / or the bulk of the equipment, and / or to simplify its use and cleaning, or in any case to make an improvement on one of the aforementioned points.
Suivant un premier aspect de l'invention, le procédé pour préparer un mélange, en particulier pour confectionner du béton ou matière analogue, dans lequel on place des ingrédients du mélange dans une cuve et pour malaxer le mélange on met la cuve en rotation autour d'un axe oblique, est caractérisé en ce qu'on utilise une cuve ayant un contour polygonal autour d'un fond transversal à l'axe de rotation.According to a first aspect of the invention, the method for preparing a mixture, in particular for making concrete or the like, in which the ingredients of the mixture are placed in a tank and to knead the mixture the tank is rotated around 'an oblique axis, is characterized in that one uses a tank having a polygonal contour around a bottom transverse to the axis of rotation.
Il a été trouvé selon l'invention que le contour polygonal de la cuve suffit pour que des fractions soient entraînées en rotation avec la cuve jusqu'à une hauteur suffisante pour qu'elles retombent ensuite d'une manière efficace pour l'action de malaxage dans la masse occupant le bas du volume intérieur de la cuve. Ainsi, la cuve peut être considérablement simplifiée, elle n'a plus besoin de saillies intérieures. La cuve est donc moins coûteuse, plus légère, plus facile à nettoyer et permet beaucoup plus facilement le puisage direct du mélange confectionné, ainsi que l'utilisation
- 3 - complète du mélange sans que des quantités importantes de mélange restent prisonnières des formes intérieures complexes d'une cuve classique munie de pales intérieures.It has been found according to the invention that the polygonal contour of the tank is sufficient for fractions to be driven in rotation with the tank to a sufficient height so that they then fall back in an effective manner for the kneading action. in the mass occupying the bottom of the interior volume of the tank. Thus, the tank can be considerably simplified, it no longer needs internal projections. The tank is therefore less expensive, lighter, easier to clean and makes it much easier to draw directly from the prepared mixture, as well as to use - 3 - complete the mixing without significant quantities of mixture remaining trapped in the complex internal shapes of a conventional tank provided with internal blades.
De préférence, on utilise comme cuve une auge amovible appropriée pour transporter le mélange sur un lieu d'utilisation du mélange après le malaxage, peur y puiser le mélange avec une truelle. Ainsi, on réduit la quantité de matériel nécessaire et on supprime au moins une opération de transvasement. L'auge peut être un article du commerce, donc à très bas prix. L'utilisateur peut posséder deux auges : l'une sert à confectionner une nouvelle quantité de mélange pendant que l'autre se trouve sur le lieu d'utilisation d'une quantité préalablement préparée. Une fois cette quantité épuisée, l'utilisateur retourne à l'appareil de mélange avec l'auge vide et la place sur l'appareil après en avoir extrait l'auge pleine qu'il emmène à son tour sur le lieu d'utilisation.Preferably, a removable trough suitable for transporting the mixture to a place of use of the mixture after kneading is used as a tank, for fear of drawing the mixture there with a trowel. Thus, the amount of material required is reduced and at least one transfer operation is eliminated. The gauge can be an article of commerce, therefore at a very low price. The user can have two troughs: one is used to make a new quantity of mixture while the other is at the place of use of a quantity previously prepared. Once this quantity has been used up, the user returns to the mixing apparatus with the empty trough and places it on the apparatus after having extracted the full trough which he in turn takes to the place of use.
Pendant le malaxage, il est avantageux de placer sur l'auge un couvercle muni d'une ouverture centrale. Grâce à l'axe de rotation oblique selon un angle qui peut être d'environ 60° par rapport à la verticale, on peut faire en sorte que le niveau de remplissage normal de la cuve soit compatible avec une absence de débordement par l'orifice central pendant la rotation de la cuve. L'orifice permet une inspection du mélange pendant la rotation de la cuve et au besoin une modification de la composition du mélange par apport d'une quantité complémentaire de tel ou tel ingrédient.During mixing, it is advantageous to place a cover provided with a central opening on the trough. Thanks to the oblique axis of rotation at an angle which can be approximately 60 ° with respect to the vertical, it is possible to ensure that the normal filling level of the tank is compatible with an absence of overflow through the orifice central during rotation of the tank. The orifice allows an inspection of the mixture during the rotation of the tank and, if necessary, a modification of the composition of the mixture by adding an additional quantity of such or such ingredient.
Suivant un autre aspect de l'invention, l'appareil de malaxage tel que bétonnière comprend - un châssis, - un support monté en rotation sur le châssis suivant un axe de rotation et équipé de moyens de positionnement peur maintenir de façon amovible une auge essentiellement polygonale de façon que l'axe de rotation soit transversal à un fend de 1 ' auge , - un couvercle de fermeture au moins partielle de 1 ' auge ,
- 4 - des n oyens d'orientation pour positionner sélectivement le sapport suivant une orientation sensiblement horizontale de manipulation et remplissage de l'auge, et une orientation inclinée de malaxage par rotation autour de l'axe. II est avantageux que les moyens d'orientation comprennent deux plans d'appui du cnâssis sur le sol, définis par une zone d'appui sensiblement parallèle au fond de l'auge et une zone d'appui oblique par rapport au fond de l'auge II suffit ainsi de basculer l'ensemble de l'appareil pour passer de l'une à l'autre des orientations. Ceci réduit considérablement la complexité de l'appareil donc son poids, son prix et son risque de panne.According to another aspect of the invention, the kneading apparatus such as a concrete mixer comprises - a chassis, - a support mounted in rotation on the chassis along an axis of rotation and equipped with positioning means for detachably maintaining a trough essentially polygonal so that the axis of rotation is transverse to a split of the trough, - an at least partial closure cover of the trough, - 4 - n oyens orientation to selectively position the contribution in a substantially horizontal orientation of handling and filling the trough, and an inclined orientation of kneading by rotation about the axis. It is advantageous that the orientation means comprise two support planes of the chassis on the ground, defined by a support zone substantially parallel to the bottom of the trough and an oblique support zone relative to the bottom of the trough It is thus sufficient to switch the entire apparatus to pass from one to the other of the orientations. This considerably reduces the complexity of the device, therefore its weight, its price and its risk of failure.

11 formant ensemble un dièdre et reliées l'une à l'autre par un coude à 120°, désigné par la référence 9 La zone d'appui 7 est sensiblement parallèle à l'embase 2 et donc au fond 6 de l'auge 4 Lorsque la zone d'appui 7 repose par son plan d'appui inférieur sur un sol 8 (figure 1), l'emnase 2 est située à une certaine hauteur au-dessus du sel grâce à une distance "n" entre l'emnase 2 et la zone d'appui 7The apparatus comprises a tubular frame 1 (FIG. 1) having, seen in profile, a general shape of a quadrilateral, more particularly of a rectangular trapezium. The frame 1 defines along the large base of the trapezoid a base 2 intended to indirectly support a mason's trough. 4 rotating around an axis 3 perpendicular to the plane ce the base 2 The substantially flat bottom 6 of the trough 4 thus supported is parallel to the plane of the base 2 and perpendicular to the axis of rotation 3 The chassis 1 further defines along the small base of the trapezoid and the oil side of the crapeze two support zones 7 and 11 together forming a dihedral and connected to each other by a 120 ° elbow, designated by the reference 9 The bearing area 7 is substantially parallel to the base 2 and therefore to the bottom 6 of the trough 4 When the support zone 7 rests by its lower support plane on a ground 8 (FIG. 1), the indemnase 2 is situated at a certain height above the salt thanks to a distance "n" between the indemnase 2 and the support zone 7
La seconde zone d'appui 11 est oblique par rapport à l'axe 3 et par rapport au fond 6 de l'auge Par simple basculement de l'ensemble de l'appareil, celui-ci peut être sélectivement positionné dans une orientation sensiblement horizontale représentée à la figure 1 pour les opérations de remplissage et de manipulation, la zone d'appui 7 étant posée sur le sol 8, ou dans une orientation inclinée de malaxage représentée à la figure 3, où la zone d'appui oblique 11 repose par son plan d'appui inférieur sur le sol sensiblement horizontal 8 Dans l'orientation oblique, le malaxage s'opère par rotation de l'auge 4 autour de l'axe 3 incliné d'environ 60° par rapport à la verticale A l'extrémité du dièdre associée à la zone d'appui 7, cette dernière est raccordée à l'embase 2 par deux coudes successifs à 90° désignés par la référence 12, séparés, suivant le quatrième côté du trapèze, par une troisième zone d'appui 13 ortnogonale à la zone d'appui parallèle 7 et à l'embase 2 Comme le montre la situation illustrée dans la demi-vue inférieure de la figure 4, la troisième zone d'appui 13 permet de faire reposer l'appareil en configuration dressée sur le soi 8, par exemple pour son remisage ou pendant le transport.The second support zone 11 is oblique with respect to the axis 3 and with respect to the bottom 6 of the trough. By simply tilting the whole of the apparatus, the latter can be selectively positioned in a substantially horizontal orientation. shown in Figure 1 for filling and handling operations, the support area 7 being placed on the ground 8, or in an inclined kneading orientation shown in Figure 3, where the oblique support area 11 rests on its lower support plane on the substantially horizontal ground 8 In the oblique orientation, the kneading takes place by rotation of the trough 4 around the axis 3 inclined by about 60 ° relative to the vertical end of the dihedral associated with the support zone 7, the latter is connected to the base 2 by two successive 90 ° elbows designated by the reference 12, separated, along the fourth side of the trapezium, by a third support zone 13 ortnogonal to the parallel support zone the 7 and at the base 2 As the situation illustrated in the lower half-view of FIG. 4 shows, the third support zone 13 allows the device to rest in the configuration erected on the body 8, for example for its storage or during transport.
Comme le montre la figure 2, le châssis i comprend comme composant principal un tube 14 recourbé en U en une extrémité libre 16 de la zone d'appui 11, constituant l'autre extrémité du dièdre Cette extrémité 16 forme une anse pour le transport αe 1 ' appareA en position dressée, ou encore pour son accrochage à un croenet mural 15 comme illustré en partie supérieure de la figure 4 à titre de variante ce l'appui par la zone d'appui 13 sur le sol 8
A partir de l'extrémité recourbée 16, le tube 14 forme deux longerons symétriques s ' étendant chacun le long de la zone d'appui oblique 11, puis le long de la zone d'appui oblique 7 et de la troisième zone d'appui 13, puis enfin parallèlement l'un à l'autre le long de l' embase 2, où les deux longerons se terminent par une extrémité libre respective 17. L'extrémité recourbée 16 se trouve sensiblement dans le plan de l'embase 2, à une certaine distance au-delà des deux extrémités libres 17. Dans la zone d'appui 7, les deux longerons sont également parallèles 1 ' un à l'autre mais plus écartés l'un de l'autre que dans l'embase 2, et ils y sont réunis par deux traverses tubulaires soudées 18.As shown in Figure 2, the chassis i comprises as main component a tube 14 curved into a U at a free end 16 of the support zone 11, constituting the other end of the dihedral This end 16 forms a handle for transport αe 1appareA in the upright position, or for its attachment to a wall bracket 15 as illustrated in the upper part of Figure 4 as a variant that the support by the support area 13 on the ground 8 From the curved end 16, the tube 14 forms two symmetrical longitudinal members each extending along the oblique support area 11, then along the oblique support area 7 and the third support area 13, then finally parallel to one another along the base 2, where the two longitudinal members terminate in a respective free end 17. The curved end 16 is located substantially in the plane of the base 2, at a certain distance beyond the two free ends 17. In the support zone 7, the two longitudinal members are also parallel 1 'to one another but more spaced from one another than in the base 2 , and they are joined there by two welded tubular crosspieces 18.
Dans les zones d'appui 11 et 13, les deux longerons convergent l'un vers l'autre de bas en haut, vers l'extrémité recourbée 16 et vers l'embase 2 respectivement.In the support zones 11 and 13, the two longitudinal members converge towards each other from bottom to top, towards the curved end 16 and towards the base 2 respectively.
L'appareil comprend en outre une boîte 19 comprenant deux canons latéraux parallèles et opposés 21 par lesquels elle est emmanchée sur les deux longerons dans leur zone composant l'embase 2. La boîte 19 comprend en outre un logement central 22 dans lequel est installé suivant l'axe de rotation 3, un palier lisse en bronze autolubrifiant 23 ouvert du côté opposé à la zone d'appui 7. La boîte 19 est immobilisée le long de 1 ' emoase 2 par deux broches 24. Chaque broche 24 traverse des trous transversaux correspondants formés dans l'un respectif des canons 21 et dans le longeron associé de l'embase 2.The apparatus further comprises a box 19 comprising two parallel and opposite lateral barrels 21 by which it is fitted on the two longitudinal members in their zone making up the base 2. The box 19 also comprises a central housing 22 in which is installed according to the axis of rotation 3, a self-lubricating bronze plain bearing 23 open on the side opposite to the support zone 7. The box 19 is immobilized along the emoase 2 by two pins 24. Each pin 24 passes through transverse holes correspondents formed in a respective one of the barrels 21 and in the associated spar of the base 2.
L'appareil comprend en outre un support 26, réalisé par exemple en tôle, comprenant une plaque de base 27 sensiblement plane et rectangulaire dont la face inférieure, tournée en service vers la boîte 19, porte un tourillon 28 destiné à s'emmancher dans le palier 23. Le tourillon 28 est relié rigidement à la plaque 27 par l'intermédiaire d'un tamcour cylindrique 29 qui est coaxial avec l'axe 3 lorsque le tourillon 28 est dans le palier 23. Le support 26, dont la plaque 27 est destinée à supporter le fond 6 de l'auge 4, comprend en outre quatre ailes latérales 31 partant chacune de l'un des côtés de la plaque 27 pour positionner l'auge 4 sur la plaque 27 de manière que le centre géométrique de l'auge 4
comcide sensiblement avec l'axe de rotation 3. En service chaque face latérale extérieure 32 de l'auge 4 s'appuie contre l'une respective des ailes 31 L'auge 4 peut typiquement être une auge du commerce, de forme générale rectangulaire, évasée en tronc de pyramide depuis son fond 6 jusqu'à un bord ouvert 33 équipé d'un renord 34 périphérique, recourbé vers 1 ' extérieur.The apparatus further comprises a support 26, made for example of sheet metal, comprising a substantially flat and rectangular base plate 27, the underside of which, turned in service towards the box 19, carries a pin 28 intended to be fitted in the bearing 23. The pin 28 is rigidly connected to the plate 27 by means of a cylindrical drum 29 which is coaxial with the axis 3 when the pin 28 is in the bearing 23. The support 26, whose plate 27 is intended to support the bottom 6 of the trough 4, further comprises four lateral wings 31 each starting from one of the sides of the plate 27 to position the trough 4 on the plate 27 so that the geometric center of the trough 4 roughly comcides with the axis of rotation 3. In service, each external lateral face 32 of the trough 4 rests against a respective one of the wings 31 The trough 4 can typically be a commercial trough, of generally rectangular shape, flared in the trunk of a pyramid from its bottom 6 to an open edge 33 equipped with a peripheral rim 34, curved towards the outside.
L'appareil comprend en outre un couvercle 36 avec quatre parois latérales 38 s ' évasant en forme de tronc de pyramide à partir d'une paroi supérieure généralement rectangulaire 37 jusqu'à un bord périphérique 39 équipé d'une lèvre 41 dirigée obliquement vers le haut et vers 1 ' extérieur La face extérieure de la lèvre 41 est capable de s'emnoîter et de se centrer dans le bord ouvert 33 de l'auge 4. La lèvre 41 forme avec les parois latérales 38 du couvercle 36 une rainure périphérique 42. Deux ailes 31 opposées du support 26 portent chacune une attache rapide 43 comprenant un bec de serrage 44 venant en prise avec le couvercle 36 dans la rainure périphérique 42 pour solliciter le couvercle 36 vers le support 26 en appuyant le fond 6 de l'auge 4 contre la plaque 27 du support 26. De cette manière, on assure à la fois la fixation, le centrage et la fermeture de l'auge 4 sans avoir à modifier une auge 4 du commerce. Le couvercle 36 présente à travers sa paroi supérieure 37 une ouverture centrale 46 centrée sur l'axe 3, munie d'un bord relevé 47. Lorsque l'appareil est dans l'orientation inclinée de malaxage (figure 3), le niveau de la masse 48 des ingrédients à malaxer est situé en-dessous de la partie la plus basse du bord périphérique de l'ouverture 46, de manière à éviter tout débordement. Ceci résulte d'un choix approprié de dimensions et en particulier ou diamètre de 1 ' ouverture 46The apparatus further comprises a cover 36 with four side walls 38 flaring in the shape of a pyramid trunk from a generally rectangular upper wall 37 to a peripheral edge 39 equipped with a lip 41 directed obliquely towards the upward and outwardly The outer face of the lip 41 is capable of nesting and of being centered in the open edge 33 of the trough 4. The lip 41 forms with the side walls 38 of the cover 36 a peripheral groove 42 Two opposite wings 31 of the support 26 each carry a quick coupler 43 comprising a clamping spout 44 engaging with the cover 36 in the peripheral groove 42 to urge the cover 36 towards the support 26 by pressing the bottom 6 of the trough 4 against the plate 27 of the support 26. In this way, it ensures both the fixing, the centering and the closing of the trough 4 without having to modify a trough 4 of the trade. The cover 36 has through its upper wall 37 a central opening 46 centered on the axis 3, provided with a raised edge 47. When the appliance is in the inclined kneading orientation (FIG. 3), the level of the mass 48 of the ingredients to be kneaded is located below the lowest part of the peripheral edge of the opening 46, so as to avoid any overflow. This results from an appropriate choice of dimensions and in particular or diameter of the opening 46
On va maintenant décrire l'utilisation de l'appareil selon l'invention, cette description incluant celle au procédé selon 1 ' invention L'appareil étant dans son orientation essentiellement horizontale de manipulation et remplissage, donc en appui sur le sol 8 par la zone d'appui 7, on place l'auge 4 dans le
- 8 - support 26, on pi; ce les ingrédients dans l'auge 4, puis le couvercle 36 sur 1 auge 4 et enfin on verrouille le couvercle 36 à l'aide des attaches rapides 43 pour aboutir à la situation représentée à la figure 1. On bascule ensuite l'appareil pour le placer dans son orientation inclinée de malaxage représentée à la figure 3 et on fait tourner autour de l'axe 3 l'ensemble constitué du support 26, de l'auge 4 et du couvercle 36, grâce au palier 23 (visible uniquement à la figure 2) porté par la boîte à palier 19. Pendant cette rotation (figure 3) le contour polygonal de l'auge 4 et du couvercle 36 autour de l'axe 3 provoque un entraînement de la masse 48 dans la rotation autour de l'axe 3. Des fragments de cette masse s'élèvent donc au-dessus du niveau de la masse puis finissent par retomber par gravité dans la masse, provoquant ainsi l'action de malaxage.We will now describe the use of the apparatus according to the invention, this description including that of the method according to the invention The apparatus being in its essentially horizontal orientation of handling and filling, therefore bearing on the ground 8 by the zone support 7, place the trough 4 in the - 8 - support 26, one pi; ce the ingredients in the trough 4, then the cover 36 on 1 trough 4 and finally we lock the cover 36 with the quick couplers 43 to arrive at the situation shown in Figure 1. We then rock the device to place it in its inclined kneading orientation shown in FIG. 3 and the assembly consisting of the support 26, the trough 4 and the cover 36 is rotated around the axis, thanks to the bearing 23 (visible only at the Figure 2) carried by the bearing box 19. During this rotation (Figure 3) the polygonal outline of the trough 4 and the cover 36 around the axis 3 causes a drive of the mass 48 in the rotation around the axis 3. Fragments of this mass therefore rise above the level of the mass and then fall back by gravity into the mass, thus causing the kneading action.
L'ouverture 46 permet d'inspecter visuellement le malaxage, et en particulier la consistance du mélange obtenu, et compléter au besoin le mélange par apport d'une quantité complémentaire de tel ou tel de ses ingrédients. Une fois le malaxage terminé, on ramène l'appareil dans son orientation sensiblement horizontale de la figure 1. On déverrouille les attaches 43 et on ôte le couvercle 36, on extrait l'auge 4 du support 26 et on emporte sur le lieu d'utilisation l'auge 4 remplie du mélange ainsi confectionné. A la fin des travaux, on extrait le support 26 du palierThe opening 46 makes it possible to visually inspect the kneading, and in particular the consistency of the mixture obtained, and supplement the mixture if necessary by adding an additional quantity of such or such of its ingredients. Once mixing has been completed, the apparatus is returned to its substantially horizontal orientation in FIG. 1. The clips 43 are unlocked and the cover 36 is removed, the trough 4 is extracted from the support 26 and taken to the place of use the trough 4 filled with the mixture thus prepared. At the end of the work, extract the support 26 from the bearing
23 comme illustré à la figure 2, puis on place le support 26 dans l'auge 4 (figure 4), on remet en place le couvercle 36 sur l'auge 4 puis on obture l'orifice 46 avec un seau 49 dont le fond vient s'appuyer sur la plaque de base 27 du support 26. Au préalable, on a placé également dans l'auge 4, qui peut alors servir de coffre à outils, une truelle, un niveau, un instrument de mesure de longueur, un fil à plomb, etc. Le seau, dont le diamètre extérieur correspond à celui de l'orifice 46, obture ce dernier et empêche les outils de s'échapper de l'auge. Le seau 49 est de préférence un seau de dosage facilitant le choix de quantités appropriées de chaque ingrédient du mélanαe. On place ensuite l'ensemble constitué
- 9 - par l'auge 4, le couvercle 36 et les objets qui y sont contenus dans le logement formé par le châssis entre l'embase 2 et la zone d'appui sensiblement parallèle 7, comme représenté à la figure 4. La longueur L de l'auge le long du rebord 34 correspond à la distance libre entre les zones 11 et 13 du châssis dans le plan où se trouve le rebord 34 dans cette configuration, de sorte que ledit ensemble est positionné de manière stable dans le logement formé par le châssis. L'appareil prend alors une configuration de remisage particulièrement compacte, propice au remisage en position dressée sur le sol 8 comme illustré dans la moitié inférieure de la figure 4 ou en suspension sur le crochet 15 comme représenté à la partie supérieure de la figure 4. Le seau 49 sert de cale appuyée sous l'embase 2, plus précisément sous la boîte à palier 19, et immobilise ainsi le support 26 contre le fond de l'auge 4 et le fond de l'auge 4 contre la zone d'appui 7 du châssis.23 as illustrated in FIG. 2, then the support 26 is placed in the trough 4 (FIG. 4), the cover 36 is replaced on the trough 4 and then the orifice 46 is closed with a bucket 49 whose bottom comes to rest on the base plate 27 of the support 26. Beforehand, we also placed in the trough 4, which can then serve as a tool box, a trowel, a level, a length measuring instrument, a plumb line, etc. The bucket, the outside diameter of which corresponds to that of the orifice 46, closes the latter and prevents the tools from escaping from the trough. The bucket 49 is preferably a dosing bucket facilitating the choice of appropriate amounts of each ingredient in the mixture. We then place the set made up - 9 - through the trough 4, the cover 36 and the objects contained therein in the housing formed by the frame between the base 2 and the substantially parallel bearing area 7, as shown in Figure 4. The length L of the trough along the rim 34 corresponds to the free distance between zones 11 and 13 of the chassis in the plane where the rim 34 is in this configuration, so that said assembly is positioned stably in the housing formed by the chassis. The apparatus then takes a particularly compact storage configuration, suitable for storage in the upright position on the ground 8 as illustrated in the lower half of FIG. 4 or suspended on the hook 15 as shown in the upper part of FIG. 4. The bucket 49 serves as a wedge supported under the base 2, more precisely under the bearing box 19, and thus immobilizes the support 26 against the bottom of the trough 4 and the bottom of the trough 4 against the bearing area 7 of the chassis.
Dans le mode de réalisation décrit jusqu'à présent, la rotation de l'auge 4 autour de l'axe 3 peut être effectuée par exemple à la main.In the embodiment described so far, the rotation of the trough 4 around the axis 3 can be carried out for example by hand.
Il est toutefois prévu selon l'invention de compléter au besoin l'appareil avec un moyen d'entraînement 51. Un bâti 52 du moyen d'entraînement 51 porte deux canons parallèles 53It is however planned according to the invention to supplement the apparatus if necessary with a drive means 51. A frame 52 of the drive means 51 carries two parallel barrels 53
(figure 2) pour l'emmanchement du moyen 51 sur les deux longerons composant l'embase 2 dans la zone située entre la boîte 19 et le coude 12 de transition avec la troisième zone d'appui 13. Pour le montage du moyen d'entraînement 51, on ôte la boîte 19, on engage le moyen 51 de manière coulissante et l'on remet en place la boîte 19. Le bâti 52 renferme un réducteur de vitesse de rotation 55 (non davantage représenté) ayant un arbre de sortie équipé d'une poulie 54 qui se trouve dans le même plan que le tambour cylindrique 29 du support 26 lorsque le tourillon 28 est en place dans le palier 23. Une courroie d'entraînement 56 accouple la poulie 54 avec le tambour 29 qui sert alors de poulie réceptrice. Pour mettre en place la courroie, il suffit de la placer autour du tambour 29 avant d'engager le tourillon 28 dans le palier 23 puis de
- 10 - passer la courroie 56 autour de la poulie 54. Le bâti 52 comprend en outre une monture formée d'une platine 57 supportant un collier 58 pour la fixation amovible d'une perceuse portative 59 dans une position telle que la broche 61 de la perceuse peut être accouplée par serrage sur l'arbre d'entrée 62 du réducteur 55. Le réducteur 55 est d'un type où l'arbre de sortie est à 90° par rapport à l'arbre d'entrée 62. Un dispositif de genouillère 64 commandée par un levier manuel 66 agit sur la boîte 19 et sur le bâti 52 du moyen d'entraînement 51 pour écarter sélectivement le moyen d'entraînement 51 du support 26 le long de l'embase 2 et tendre ainsi la courroie 56, ou au contraire rapprocher le bâti 52 du support 26 pour détendre la courroie 56 et permettre son démontage, et aussi pour ramener le moyen d'entraînement 51 et en particulier la platine 57 en une position escamotée (figure 4) entre les deux longerons du châssis.(Figure 2) for the fitting of the means 51 on the two side members of the base 2 in the area between the box 19 and the elbow 12 of transition with the third support area 13. For mounting the means of drive 51, the box 19 is removed, the means 51 are slidably engaged and the box 19 is replaced. The frame 52 contains a speed reduction gear 55 (not shown any more) having an output shaft equipped a pulley 54 which is in the same plane as the cylindrical drum 29 of the support 26 when the pin 28 is in place in the bearing 23. A drive belt 56 couples the pulley 54 with the drum 29 which then serves as take-up pulley. To install the belt, simply place it around the drum 29 before engaging the pin 28 in the bearing 23 and then - 10 - pass the belt 56 around the pulley 54. The frame 52 further comprises a frame formed by a plate 5 7 supporting a collar 58 for the removable fixing of a portable drill 59 in a position such as the spindle 61 of the drill can be coupled by clamping on the input shaft 62 of the reduction gear 55. The reduction gear 55 is of a type where the output shaft is at 90 ° relative to the input shaft 62. A toggle device 64 controlled by a manual lever 66 acts on the box 19 and on the frame 52 of the drive means 51 to selectively separate the drive means 51 from the support 26 along the base 2 and thus tension the belt 56, or on the contrary bring the frame 52 of the support 26 to relax the belt 56 and allow its disassembly, and also to bring the drive means 51 and in particular the plate 57 into a retracted position (Figure 4) between the two rails of the chassis.
Lorsque le moyen d'entraînement 51 a été mis en place et que la courroie 56 a été tendue à l'aide du levier 66 , la rotation de l'auge 4 alors que l'appareil est dans l'orientation oblique de malaxage (figure 3) peut être obtenue par simple activation de la perceuse 59.When the drive means 51 has been put in place and the belt 56 has been tensioned using the lever 66, the rotation of the trough 4 while the apparatus is in the oblique kneading orientation (FIG. 3) can be obtained by simple activation of the drill 59.
Pour le remisage, après avoir ôté le support 26 et la perceuse 59, on enlève la courroie 56, on place le moyen d'entraînement 51 en position escamotée par coulissement le long de l'embase 2 au moyen du levier 66, et on termine le remisage comme décrit précédemment en référence à la figure 4.For storage, after having removed the support 26 and the drill 59, the belt 56 is removed, the drive means 51 are placed in the retracted position by sliding along the base 2 by means of the lever 66, and one finishes storage as described above with reference to Figure 4.
Bien-entendu, l'invention n'est pas limitée aux exemples décrits et représentés . Le mode de motorisation décrit a l'avantage de pouvoir être commercialisé sous forme d'option aisément adaptable sur un matériel de base à rotation manuelle. En outre, la réalisation sous forme d'un simple réducteur ayant comme arore d'entrée un arnre de prise de force adaptable à une perceuse permet une réalisation particulièrement économique. Mais il est possible de réaliser le moyen d'entraînement sous une forme intégrant un moteur, et/ou de réaliser le moyen d'entraînement monté à demeure sur l'appareil et en particulier sur son châssis .
- 11 -Of course, the invention is not limited to the examples described and shown. The motorization method described has the advantage of being able to be marketed as an option that can easily be adapted to basic equipment with manual rotation. In addition, the realization in the form of a simple reducer having as input edge a PTO strap adaptable to a drill allows a particularly economical embodiment. However, it is possible to make the drive means in a form incorporating a motor, and / or to make the drive means permanently mounted on the device and in particular on its chassis. - 11 -
