Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne un dispositif de vidage de benne à béton.The present invention relates to a device for emptying concrete bucket.

ARRIÈRE-PLAN TECHNOLOGIQUE DE L'INVENTIONTECHNOLOGICAL BACKGROUND OF THE INVENTION

Le procédé de coulage du béton dans des coffrages au moyen d'un type de bennes dont la base présente une ouverture et un tuyau d'écoulement souple est connu de longue date.The process of pouring concrete into formwork using of a type of skips whose base has an opening and a flexible drain pipe has been known for a long time.

Ces bennes sont conformées de façons très diverses mais, dans la plupart des cas, leur base est en forme de tronc de cône inversé ou en forme de tronc de pyramide inversé. L'orifice de vidage inférieur de telles bennes est fermé par un obturateur, à commande manuelle ou motorisé, dont la conception mécanique est aussi extrêmement variable.These skips are shaped in very different ways but, in most cases their base is in the form of a truncated cone inverted or in the form of an inverted pyramid trunk. The orifice of lower emptying of such skips is closed by a shutter, to manual or motorized control, the mechanical design of which is also extremely variable.

La conception de cet obturateur est en soi assez complexe, car les contraintes d'utilisation sont sévères et les normes de sécurité et de qualité sont contraignantes, telles par exemple :

  • démontage facile indispensable pour assurer le nettoyage de l'obturateur en cas de blocage du mécanisme par les agrégats, ou même en cas de durcissement du béton,
  • commande à distance du mécanisme,
  • maintien de la continuité de la veine de béton pour éviter la souillure des édifices et des utilisateurs par les projections extérieures,
The design of this shutter is in itself quite complex, because the constraints of use are severe and the safety and quality standards are binding, such as for example:
  • easy disassembly essential to ensure the cleaning of the shutter in case of blocking of the mechanism by aggregates, or even in case of hardening of the concrete,
  • remote control of the mechanism,
  • maintenance of the continuity of the concrete vein to avoid soiling of buildings and users by external projections,

Un exemple de solution apportée à ces problèmes est décrit dans le brevet américain US-3.146.924 publié le 1 septembre 1964 au nom de R. Cozadd et al. L'écoulement du béton est alors classiquement contrôlé par des mâchoires formant vanne. L'originalité de ce dispositif est que son étanchéité est assurée par une enveloppe souple fixée, d'une part, sur le col formant la base de la benne et, d'autre part, sur les mâchoires elles-mêmes.An example of a solution to these problems is described in US patent 3,146,924 published September 1, 1964 in the name of R. Cozadd et al. The concrete flow is then conventionally controlled by jaws forming a valve. The originality of this device is that its tightness is ensured by a flexible envelope fixed, on the one hand, on the collar forming the base of the bucket and, on the other hand, on the jaws themselves.

On conçoit cependant facilement que, si elle semble avoir élégamment résolu les problèmes évoqués ci-dessus, cette pièce souple semble en revanche imposer une autre contrainte de maintenance liée à sa fragilité et à l'évolution négative possible de ses caractéristiques.It is easy to see, however, that if it seems to have elegantly solved the problems mentioned above, this piece flexible, on the other hand, seems to impose another constraint of maintenance linked to its fragility and negative development possible of its characteristics.

D'autres solutions tendant aux mêmes buts, mais ayant l'avantage de reposer entièrement sur des éléments rigides, ont déjà été proposées par le déposant de la présente demande.Other solutions tending to the same goals, but having the advantage of being based entirely on rigid elements, have already proposed by the applicant of this request.

Ainsi, dans le brevet français FR-2.590.306 au nom de A. Gilles, publié le 22 mai 1987, il est décrit un dispositif de vidage amovible assurant la continuité de la veine de béton et le sectionnement de celle-ci dans un boítier situé au droit du fond de la benne. Selon ce même dispositif, une buse de réduction solidaire d'un tuyau souple réalise le guidage de l'écoulement.Thus, in French patent FR-2,590,306 in the name of A. Gilles, published on May 22, 1987, describes a device for removable emptying ensuring the continuity of the concrete vein and the sectioning of the latter in a box located to the right of the bottom of the bucket. According to this same device, a nozzle of integral reduction of a flexible pipe guides flow.

Un autre ensemble d'obturation, amovible également, est divulgué dans le brevet français FR-2.637.834 publié le 20 avril 1990, également au nom de A. Gilles. Selon cette autre technique, la base de la benne à béton est équipée d'un volet d'obturation en deux parties actionné par un volant. Le béton est coulé dans un entonnoir s'étendant vers le haut, autour du volet et de son mécanisme de commande, et se prolongeant vers le bas par un tuyau souple.Another shutter assembly, also removable, is disclosed in French patent FR-2,637,834 published on April 20 1990, also on behalf of A. Gilles. According to this other technical, the base of the concrete skip is equipped with a flap two-part shutter operated by a steering wheel. Concrete is poured into an upwardly extending funnel around the shutter and its control mechanism, and extending towards the down by a flexible hose.

Ces deux derniers dispositifs sont des améliorations sensibles aux systèmes ayant fait l'objet des demandes de brevets français FR-2.542.028 et FR-2.607.853 du même inventeur, publiées antérieurement, respectivement le 7 septembre 1984 et le 10 juin 1988.These last two devices are improvements sensitive to systems that have been the subject of requests for French patents FR-2,542,028 and FR-2,607,853 from the same inventor, previously published on September 7, 1984 and June 10, 1988.

Notamment, le système de vidage, qui était l'objet de la demande FR-2.607.853, était grevé par des coûts de fabrication et d'exploitation excessifs dus au mécanisme complexe de double volets d'obturation et d'embiellage. Une telle complexité n'existe plus dans la version simplifiée décrite dans le brevet FR-2.637.834.In particular, the emptying system, which was the subject of the application FR-2,607,853, was burdened by manufacturing costs and excessive exploitation due to the complex mechanism of double shutters and connecting rods. Such complexity no longer exists in the simplified version described in the patent FR-2637834.

Cependant, le dispositif de vidage de benne à béton selon les spécifications du brevet FR-2.590.306 cité ci-dessus présente l'inconvénient majeur de ne pas assurer une étanchéité parfaite au droit du dispositif de sectionnement de la veine dans le cas de l'utilisation de bétons très liquides ou auto-plaçants de plus en plus courants.However, the concrete bucket emptying device according to the specifications of patent FR-2,590,306 cited above has the major drawback of not ensuring a seal perfect in line with the vein sectioning device in the case of the use of very liquid or self-placing concretes more and more common.

La structure du système objet du brevet FR-2.637.834 n'assure pas non plus une continuité parfaite de l'écoulement du béton. De plus, ce dispositif présente des risques importants de débordement ne lui permettant pas de satisfaire totalement aux objectifs de propreté et de sécurité initiaux.The structure of the system which is the subject of patent FR-2,637,834 also does not ensure perfect continuity of the flow of concrete. In addition, this device presents significant risks of overflow does not allow it to fully meet the initial cleanliness and safety objectives.

DESCRIPTION GÉNÉRALE DE L'INVENTIONGENERAL DESCRIPTION OF THE INVENTION

La présente invention vise donc à pallier les inconvénients des dispositifs de vidage de benne à béton évoqués précédemment, c'est-à-dire comportant de haut en bas:

  • des moyens d'obturation agencés à la base de la benne par des premiers moyens de fixation,
  • des moyens de réception du béton échappé desdits moyens d'obturation, ces moyens de réception étant formés d'une enveloppe ou entonnoir qui entoure les moyens d'obturation et qui est agencée autour de ces derniers par des deuxièmes moyens de fixation,
  • des moyens d'écoulement du béton agencés à la partie inférieure des moyens d'obturation par des troisièmes moyens de fixation.
The present invention therefore aims to overcome the drawbacks of the concrete bucket emptying devices mentioned above, that is to say comprising from top to bottom:
  • sealing means arranged at the base of the bucket by first fixing means,
  • means for receiving the concrete escaped from said closure means, these reception means being formed of an envelope or funnel which surrounds the closure means and which is arranged around the latter by second fixing means,
  • concrete flow means arranged at the bottom of the sealing means by third fastening means.

Elle a précisément pour objet un dispositif de ce type dont la caractéristique essentielle est que les moyens d'obturation sont prolongés vers le bas par une manchette dont le bord inférieur de la paroi affleure continûment la surface intérieure de l'enveloppe de réception du béton.Its specific object is a device of this type, the essential characteristic is that the shutter means are extended downwards by a cuff whose edge bottom of the wall is flush with the interior surface of the concrete receiving envelope.

Avantageusement, au moins une partie de la section d'entrée supérieure de l'enveloppe de réception est située au niveau ou au-dessus de la base de la benne.Advantageously, at least part of the inlet section top of the receiving envelope is located at or above the base of the bucket.

De préférence, au moins une partie de la section d'entrée supérieure de cette enveloppe de réception est adaptée au passage des moyens de commande des moyens d'obturation.Preferably, at least part of the inlet section top of this receiving envelope is suitable for passage of the control means of the shutter means.

Une caractéristique additionnelle du dispositif de vidage de benne à béton selon l'invention est que la manchette est de section rectangulaire, préférentiellement carrée, et présente dans sa partie supérieure, d'une part, deux rampes symétriques en arc de cercle, de cordes sensiblement horizontales, agencées sur deux faces opposées, et, d'autre part, une fente transversale aménagée dans une face adjacente dite arrière et reliant les extrémités en vis-à-vis desdites rampes. Ces rampes guident un secteur cylindrique qui traverse la fente transversale et bute sur l'autre face adjacente. La partie supérieure de la manchette munie de ces rampes et de ce secteur cylindrique coulissant dans la fente transversale constitue ainsi les moyens d'obturation du dispositif de vidage.An additional feature of the emptying device concrete bucket according to the invention is that the cuff is rectangular section, preferably square, and present in its upper part, on the one hand, two symmetrical ramps in an arc, of substantially horizontal strings, arranged on two opposite sides, and, on the other hand, a slit transverse arranged in an adjacent face called rear and connecting the ends opposite said ramps. These ramps guide a cylindrical sector which crosses the slit transverse and abuts on the other adjacent face. The part upper cuff with these ramps and this sector cylindrical sliding in the transverse slot constitutes thus the means for closing the emptying device.

La forme générale de l'enveloppe de réception du dispositif de vidage selon l'invention est de manière avantageuse celle d'un entonnoir, trémie ou analogue. De préférence, elle est celle d'un tronc de cône renversé ou d'un tronc de pyramide renversé.The general shape of the receiving envelope of the device of emptying according to the invention is advantageously that a funnel, hopper or the like. Preferably, it is that of an inverted truncated cone or a pyramid trunk reversed.

On tire bénéfice de premiers moyens de fixation constitués par deux brides, tandis que les deuxièmes moyens de fixation sont constitués par des pattes réparties à l'intérieur de l'enveloppe, préférentiellement au nombre de quatre.We benefit from the first fixing means by two flanges, while the second fixing means are made up of legs distributed inside the envelope, preferably four in number.

Selon une variante, les pattes constituant les deuxièmes moyens de fixation sont télescopiques.According to a variant, the legs constituting the second fixing means are telescopic.

Selon une autre variante, les deuxièmes moyens de fixation sont constitués par une poignée posée sur deux pattes soudées en partie arrière de la manchette et par un dispositif d'accrochage rapide en partie avant de la manchette, cet ensemble permettant le basculement de l'enveloppe de réception.According to another variant, the second fixing means consist of a handle placed on two legs welded in rear part of the cuff and by a hooking device fast in the front part of the cuff, this set allowing the tilting of the reception envelope.

Avantageusement, les troisièmes moyens de fixation sont constitués par un ou plusieurs colliers.Advantageously, the third fastening means are made up of one or more necklaces.

La présente invention concerne aussi un procédé adapté à la fabrication du dispositif de vidage de benne à béton précédemment décrit, ledit procédé étant remarquable en ce que le tracé du bord inférieur de la paroi de la manchette est déterminé par ordinateur en fonction de la forme de l'enveloppe de réception et de la forme de la manchette.The present invention also relates to a method suitable for manufacture of the concrete bucket emptying device previously described, said method being remarkable in that the outline of the lower edge of the wall of the cuff is determined by computer according to the shape of the envelope and the shape of the cuff.

Ces quelques spécifications essentielles rendent évidents pour l'homme de métier les avantages apportés par le dispositif de vidage de benne à béton selon l'invention par rapport à l'état de la technique antérieur. En particulier, le dispositif selon l'invention assure à l'utilisateur la propreté et la sécurité, tout en étant d'un coût économique satisfaisant et compatible avec une utilisation de longue durée, et ce du fait de la possibilité et de la facilité de remplacement des pièces d'usure à moindre coût.These few essential specifications make it obvious for the skilled person the advantages brought by the device emptying the concrete bucket according to the invention with respect to the state of the prior art. In particular, the device according to the invention provides the user with cleanliness and safety, while being of satisfactory economic cost and compatible with long-term use due to the fact the possibility and ease of replacing parts wear at lower cost.

Les spécifications détaillées de l'invention sont données dans la description qui suit en liaison avec les dessins ci-joints. Il est à noter que ces dessins n'ont d'autre but que d'illustrer le texte de la description et ne constituent en aucune sorte une limitation de la portée de l'invention.Detailed specifications of the invention are given in the following description in conjunction with the accompanying drawings.

    • DESCRIPTION D'UNE FORME D'EXÉCUTION PRÉFÉRÉE DE L'INVENTIONDESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

    Dans une forme de réalisation préférée de l'invention, le dispositif de vidage 1 représenté sur la Figure 1 s'adapte par une bride 2 carrée, de manière connue en soi, à la base 3 d'une benne à béton en forme de tronc de pyramide inversé munie de la bride carrée 4 correspondante à la bride 2.In a preferred embodiment of the invention, the emptying device 1 shown in Figure 1 adapts by a square flange 2, in a manner known per se, at the base 3 of a concrete bucket in the shape of an inverted pyramid trunk with the square flange 4 corresponding to flange 2.

    La partie supérieure du dispositif de vidage 1, adjacente à cette bride 2, est constituée par une manchette verticale 5, de section carrée, comportant des moyens d'obturation commandés manuellement par un opérateur.The upper part of the emptying device 1, adjacent to this flange 2, is constituted by a vertical cuff 5, of square section, comprising controlled closure means manually by an operator.

    Pour ce faire, les parties supérieures de deux faces opposées de la manchette 5, dites faces latérales, présentent chacune intérieurement une rampe 6,7, en arc de cercle, agencée dans une même section horizontale, destinée à guider un obturateur 8 formé par un secteur cylindrique de rayon correspondant. L'obturateur 8, en conséquence en forme de lame incurvée, pénètre à l'intérieur de la manchette 5 par une fente 9 aménagée dans la paroi arrière 5a située entre les rampes 6,7 et arrive en butée sur la paroi opposée, qui est pleine et fermée. L'obturateur 8 est soudé sur une barre 10 portée par deux bras mobiles 11,12 articulés, selon un axe XX' situé au-dessus de la manchette, sur deux bras fixes 13,14 solidaires de la manchette 5 et soudés extérieurement sur les faces latérales de celle-ci.To do this, the upper parts of two faces opposite of the cuff 5, called lateral faces, have each internally a ramp 6,7, in an arc of a circle, arranged in the same horizontal section, intended to guide a shutter 8 formed by a cylindrical sector of radius corresponding. The shutter 8, therefore in the form of a blade curved, penetrates inside the cuff 5 through a slit 9 arranged in the rear wall 5a located between the ramps 6.7 and comes up against the opposite wall, which is full and closed. The shutter 8 is welded to a bar 10 carried by two movable arms 11,12 articulated, along an axis XX 'located above of the cuff, on two fixed arms 13,14 secured to the cuff 5 and welded externally on the lateral faces of it.

    La manoeuvre de l'obturateur est réalisée au moyen de deux bras de levier 15,16 fixés à une extrémité sur les bras mobiles 11,12, au voisinage de la base de ces derniers, et assemblés par deux barres transversales 17,18 à l'autre extrémité. La barre intercalaire 17 est reliée par un ressort de rappel 19 à un point fixe du corps de la benne 3 afin de maintenir l'obturateur 8 en position fermée au repos. Un câble de commande 20 relié à la barre extrémale 18 permet de dégager l'obturateur 8 de l'intérieur de la manchette 5 par simple traction. L'angle de pivotement de l'ensemble "obturateur 8 - bras mobiles 11,12 - bras de levier 15, 16 et barres 10, 17, 18" est limité par une ou deux butées 21 solidaires du ou des bras de levier 15,16 portant en fin de course sur le ou les bras fixes 13,14.The shutter is operated by two lever arms 15,16 fixed at one end to the movable arms 11,12, near the base of the latter, and assembled by two cross bars 17,18 at the other end. Bar interlayer 17 is connected by a return spring 19 to a fixed point of the body of the bucket 3 in order to maintain the shutter 8 in the closed position at rest. A control cable 20 connected to the end bar 18 makes it possible to release the shutter 8 from inside the cuff 5 by simple pull. The angle of pivoting of the shutter assembly 8 - movable arms 11.12 - lever arms 15, 16 and bars 10, 17, 18 "is limited by a or two stops 21 integral with the lever arm (s) 15,16 bearing at the end of the travel on the fixed arm (s) 13.14.

    La fente transversale 9 aménagée dans la paroi arrière de la manchette 5 est susceptible de laisser s'échapper un béton particulièrement fluide ou la laitance. Pour éviter les souillures et les projections, un entonnoir 22 en forme de tronc de cône inversé ou en forme de tronc de pyramide inversé est rendu solidaire de la manchette 5 au moyen de quatre pattes 23. Cet entonnoir 22 est démontable. Il est agencé de telle manière que le bord supérieur 33 de la partie de la section d'entrée en vis-à-vis de la fente transversale 9 s'élève au moins au niveau de la bride 4 de la base 3 de la benne, donc nettement au-dessus de ladite fente 9.The transverse slot 9 arranged in the rear wall of the cuff 5 is likely to let escape a concrete particularly fluid or milt. To avoid soiling and splashing, a trunk-shaped funnel 22 inverted cone or inverted pyramid-shaped trunk is secured to the cuff 5 by means of four tabs 23. This funnel 22 is removable. It is arranged in such a way that the upper edge 33 of the part of the entry section in opposite the transverse slot 9 rises at least at the level of the flange 4 of the base 3 of the bucket, so clearly above of said slot 9.

    Les bords inférieurs 5b de la manchette 5 sont découpés selon les courbes d'intersection des plans verticaux des parois avec le cône d'axe vertical de l'entonnoir 22, c'est-à-dire selon des segments d'hyperboles.The lower edges 5b of the cuff 5 are cut out according to the intersection curves of the vertical planes of the walls with the vertical axis cone of the funnel 22, i.e. according to segments of hyperbolas.

    Des moyens modernes de découpe sont mis en oeuvre (Conception assistée par ordinateur et machines à commande numérique) pour obtenir une bonne précision avec un coût acceptable.Modern cutting means are used (Design computer assisted and numerically controlled machines) for obtain good accuracy with an acceptable cost.

    Grâce à cette forme particulière des bords inférieurs 5b de la manchette 5, ceux-ci affleurent au plus près la paroi intérieure de l'entonnoir 22. L'absence de rupture notable entre la manchette 5 et l'entonnoir 22 assure une semi continuité de la veine de béton qui est particulièrement satisfaisante.Thanks to this particular shape of the lower edges 5b of cuff 5, these are as close as possible to the wall inside of the funnel 22. The absence of a significant break between the cuff 5 and the funnel 22 ensures a semi continuity of the concrete vein which is particularly satisfactory.

    Le bord supérieur de l'entonnoir 22 est découpé en 31 du côté opposé à la fente transversale 9 pour laisser le libre passage aux moyens de commande de l'obturateur 8, c'est-à-dire les deux bras de levier 15, 16 assemblés par les deux barres transversales 17,18, la première 17 étant reliée par un ressort de rappel 19 à un point fixe de la benne 3 et la seconde 18 étant reliée au câble de commande 20, en l'occurrence une corde.The upper edge of the funnel 22 is cut at 31 from the side opposite to the transverse slot 9 to leave the free passage to the shutter control means 8, that is to say the two lever arms 15, 16 assembled by the two bars 17,18 transverse, the first 17 being connected by a spring return 19 at a fixed point on bucket 3 and the second 18 being connected to the control cable 20, in this case a cord.

    L'extrémité avant 32 de la découpe 31 est donc plus basse que le bord supérieur 33 de l'entonnoir 22, mais avantageusement cette extrémité 32 est néanmoins située au-dessus de la fente 9.The front end 32 of the cutout 31 is therefore lower than the upper edge 33 of the funnel 22, but advantageously this end 32 is nevertheless located above the slot 9.

    Sur la section inférieure tubulaire et cylindrique 26 d'évacuation de l'entonnoir 22 est adapté un tuyau souple 24 fixé au moyen d'un collier 25.On the tubular and cylindrical lower section 26 evacuation of the funnel 22 is adapted a flexible pipe 24 attached with a clamp 25.

    Le dispositif de vidage pour benne à béton décrit ci-dessus constitue un ensemble compact facilement démontable en désolidarisant les deux brides d'assemblage supérieures 2,4. Les différents éléments le constituant sont de préférence réalisés en acier, en alliage léger ou en matériaux composites. Certains sont avantageusement des pièces de fonderie.The emptying device for concrete bucket described above constitutes a compact assembly that can be easily dismantled separating the two upper assembly flanges 2.4. The different components are preferably made made of steel, light alloy or composite materials. Some are advantageously foundry pieces.

    Selon deux variantes de l'invention, les pattes 23 de fixation de l'entonnoir 22 sont remplacées par un dispositif permettant de basculer l'entonnoir 22, ou de le déplacer verticalement, de bas en haut et inversement, de façon à permettre un nettoyage plus aisé de l'ensemble.According to two variants of the invention, the legs 23 of fixing of the funnel 22 are replaced by a device allowing to tilt the funnel 22, or to move it vertically, from bottom to top and vice versa, so that allow easier cleaning of the assembly.

    Dans la variante à basculement (Figures 2 à 16), l'entonnoir 22 solidaire de la manchette 5 sera judicieusement positionné par l'intermédiaire d'une poignée en rond 28 posée sur les extrémités de deux pattes 29 soudées extérieurement à la manchette 5, sur la paroi arrière 5a de celle-ci, et d'un dispositif 30 d'accrochage rapide sur l'avant.In the tilting variant (Figures 2 to 16), the funnel 22 secured to the cuff 5 will be judiciously positioned by means of a round handle 28 placed on the ends of two legs 29 welded externally to the cuff 5, on the rear wall 5a thereof, and a device 30 for quick attachment on the front.

    Dans la variante à déplacement vertical, les pattes 23 seront prévues télescopiques.In the variant with vertical displacement, the legs 23 will be telescopic.

    Afin d'améliorer encore l'étanchéité, il pourra être aisément fixé un joint souple ou rigide en bas de la manchette.In order to further improve the seal, it may be easily attached a flexible or rigid seal at the bottom of the cuff.

    L'entonnoir 22 peut, selon les besoins et/ou les applications, être en forme de tronc de cône inversé (Figures 1 à 10) ou en forme de tronc de pyramide inversé (Figures 11 à 16) .The funnel 22 can, as required and / or applications, be shaped like an inverted truncated cone (Figures 1 to 10) or in the form of an inverted pyramid trunk (Figures 11 to 16).

    Dans le second cas, il est clair que les bords inférieurs 5b de la manchette 5 sont rectilignes et horizontaux, et non plus découpés selon des segments d'hyperboles. In the second case, it is clear that the lower edges 5b of the cuff 5 are straight and horizontal, and no longer cut into segments of hyperbolas.

    Comme il va de soi, l'invention ne se limite pas au seul mode d'exécution préférentiel décrit ci-dessus.It goes without saying that the invention is not limited to only preferred embodiment described above.

    Elle embrasse au contraire toutes les variantes possibles de réalisation. Le remplacement de la liaison par brides 2,4 carrées par toutes autres formes de brides (par exemple rectangulaires, rondes) ne sortirait notamment pas du cadre de l'invention. Il en va de même du remplacement des butées latérales 21 par une butée centrale qui équiperait la barre intercalaire 17 et porterait en fin de course en partie supérieure de la pièce 27 soudée en partie avant de l'entonnoir 22 (Figure 2).On the contrary, it embraces all possible variants of production. Replacement of the connection with flanges 2,4 square by all other forms of flanges (for example rectangular, round) would in particular not be outside the scope of the invention. The same applies to the replacement of the stops lateral 21 by a central stop which would equip the bar interlayer 17 and would bear at the end of the race in part upper part 27 welded in front of the funnel 22 (Figure 2).

    De préférence, les deux brides 2,4 sont boulonnées, de telle sorte que l'ensemble obturateur est séparable de la benne et interchangeable. Pour autant, la liaison est étanche. Dans toute autre construction dans laquelle il ne sera pas nécessaire de prévoir un ensemble obturateur interchangeable, il sera alors possible d'utiliser divers autres procédés de liaison des brides entre elles, tels que le soudage ou le collage.Preferably, the two flanges 2,4 are bolted, such that so that the shutter assembly is separable from the bucket and interchangeable. However, the connection is tight. In all other construction in which it will not be necessary to provide an interchangeable shutter assembly, it will then various other flange bonding methods can be used between them, such as welding or gluing.

    Il va de soi également que, selon les besoins, la commande manuelle de l'obturateur 8 sera avantageusement remplacée par une commande électromécanique, hydraulique, pneumatique ou par tout autre moyen de commande équivalent.It also goes without saying that, as required, the order manual shutter 8 will advantageously be replaced by electromechanical, hydraulic, pneumatic or by any other equivalent control means.
