Abstract

The vehicle has a support unit and a fixation unit supporting and fixing a threshing machine (M), and a stop mechanism (60) cooperated with a threshed post to position the vehicle and the machine with respect to the threshed post. The threshing machine is placed in a correct position for threshing another post. The mechanism includes a mobile stop moved between an active position and a feathered pitch position. The active position laterally protrudes with respect to the vehicle, and is in contact with the threshed post, and pitch position is relieved from the threshed post.

Description

La présente invention concerne le domaine des travaux publics et plus précisément un matériel pouvant être utilisé notamment pour la mise en place de poteaux supportant des glissières de sécurité le long de voies routières de toutes catégories.The present invention relates to the field of public works and more specifically to a material that can be used in particular for the establishment of poles supporting guardrails along roadways of all categories.

Les glissières de sécurité disposées le long des voies routières sont fixées sur des poteaux qui sont battus dans le sol au moyen de machines de battage appelées aussi sonnettes.The guardrails along the roadways are attached to posts that are beaten in the ground by means of threshing machines also called bells.

Les poteaux recevant les glissières sont à peu près équidistants, la distance entre deux poteaux adjacents étant en général de deux ou quatre mètres, un point important étant que ces distances soient respectées de façon aussi précise que possible.The posts receiving the slides are approximately equidistant, the distance between two adjacent posts being generally two or four meters, an important point being that these distances are respected as accurately as possible.

En dehors de cette condition de distance entre poteaux, il est également important que ces glissières et par conséquent leurs poteaux de support suivent un tracé précis.Apart from this condition of distance between posts, it is also important that these slides and therefore their support posts follow a precise path.

Selon la technique connue la plus courante, on utilise pour guider la machine de battage un chemin de roulement qui est constitué par les glissières métalliques elles-mêmes qui sont donc dans un premier temps placées sur le sol pour servir de chemin de roulement avant d'être ensuite reprises et utilisées dans leur fonction normale de glissière au fur et à mesure de l'avancement de la machine de battage.According to the most common known technique, is used to guide the threshing machine a raceway which is constituted by the metal rails themselves, which are therefore initially placed on the ground to serve as a raceway before then be taken back and used in their normal slide function as the threshing machine progresses.

Une telle technique implique des manipulations longues et pénibles et peut entraîner des accidents relativement fréquents. En effet, chaque glissière longue de quatre mètres pèse environ 48 kilos. Pour être utilisées comme chemin de roulement, ces glissières doivent être dans un premier temps déchargées au sol, emboîtées les unes dans les autres et alignées suivant un tracé défini, tout cela manuellement. La machine de battage roule sur ce chemin et elle est positionnée tous les deux ou quatre mètres, pour permettre à l'opérateur de battre les poteaux. Lorsqu'un poteau a été battu, l'opérateur fait avancer la machine jusqu'à l'emplacement du poteau suivant. La glissière qui est libérée à l'arrière de la machine est à nouveau manipulée par deux ouvriers et fixée alors sur les poteaux de support.Such a technique involves long and painful manipulations and can lead to relatively frequent accidents. Indeed, each slide four meters long weighs about 48 kilos. To be used as a raceway, these slides must first be unloaded on the ground, nested in one another and aligned in a defined pattern, all manually. The threshing machine rolls on this path and is positioned every two or four meters to allow the operator to beat the posts. When a pole has been beaten, the operator advances the machine to the next post. The slide that is released at the back of the machine is again handled by two workers and then fixed on the support posts.

On a cherché à éviter ces manipulations pénibles et consommatrices de temps en proposant des machines plus sophistiquées nécessitant pour les transporter des camions avec remorques.We have tried to avoid these painful and time-consuming manipulations by proposing more sophisticated machines requiring to transport trucks with trailers.

Toutefois, de telles machines ne conviennent pas pour tous les chantiers, notamment pour des raisons d'encombrement. De plus, on ne dispose pas toujours de plans permettant d'utiliser des appareils topographiques pour déterminer le bon tracé de positionnement des poteaux.However, such machines are not suitable for all sites, especially for reasons of space. In addition, there are not always plans to use topographic devices to determine the correct placement pattern of the posts.

Par ailleurs, de telles machines impliquent de faire appel à un personnel plus qualifié et sont d'un coût plus élevé aussi bien à l'achat qu'en utilisation.Moreover, such machines involve the use of more qualified personnel and are of a higher cost both in purchase and in use.

Le document FR 2 520 402 divulgue un engin de support et de positionnement qui présente en partie les caractéristiques du préambule de la revendication 1.The document FR 2 520 402 discloses a support and positioning apparatus which presents in part the features of the preamble of claim 1.

Le but de cette invention est donc de proposer un engin permettant d'éviter d'utiliser les chemins de roulement de la technique antérieure, mais qui soit néanmoins de construction et d'utilisation simples et soit particulièrement économique aussi bien à la fabrication qu'à l'emploi.The purpose of this invention is therefore to provide a machine to avoid using the raceways of the prior art, but which is nevertheless simple in construction and use and is particularly economical both in the manufacture and employment.

Cet ensemble de compresseur n'est pas représenté au dessin.The machine according to the invention comprises two main parts A and B, which will be described in more detail below and which are associated with a set of self-propelled compressor, known per se, which, as will be seen later, in ensures the supply of pressurized air and the feeding of the threshing machine. This compressor assembly is not shown in the drawing.

La partie A constitue un chariot automoteur formé d'un châssis 10 de forme générale rectangulaire allongée, muni à sa partie arrière d'une roue folle 12, disposée dans le logement ménagé entre les deux longerons 14 de ce châssis. II comporte de plus à sa partie avant deux roues motrices et directrices 16 associées à un ensemble moteur et de transmission 18 ainsi qu'à un mécanisme de direction, qui sont de construction traditionnelle et qui ne seront donc pas décrits en détail.Part A is a self-propelled carriage formed of a chassis 10 of elongated rectangular overall shape, provided at its rear part with a idler wheel 12, disposed in the housing formed between the two longitudinal members 14 of this frame. It further comprises at its front portion two driving and steering wheels 16 associated with a motor and transmission assembly 18 as well as a steering mechanism, which are of traditional construction and therefore will not be described in detail.

Tout au plus peut-on indiquer que le moteur est de préférence de type pneumatique alimenté par le compresseur mentionné précédemment et que l'ensemble moto-propulseur comprenant distributeur, moteur débrayable, transmission par chaîne et pignons, frein, etc. est un ensemble connu qui est disponible chez de nombreux fabricants d'outils et de moteurs pneumatiques. Le compresseur a de préférence un débit supérieur ou égal à 5000 I/min.At most we can say that the motor is preferably of the pneumatic type powered by the compressor mentioned above and that the motor-propulsion unit comprising distributor, disengageable motor, transmission chain and pinions, brake, etc.. is a known assembly that is available from many manufacturers of pneumatic tools and motors. The compressor preferably has a flow rate greater than or equal to 5000 l / min.

Au voisinage de sa partie avant, le châssis 10 supporte une plateforme 20 sur laquelle peut se tenir l'opérateur pour avoir un accès aisé à un ensemble 22 de commande et de direction comportant un levier 24 de commande de marche-arrêt du moteur et un volant de direction 26.In the vicinity of its front portion, the frame 10 supports a platform 20 on which the operator can be held for easy access to a control and steering assembly 22 comprising a lever 24 for starting and stopping the engine and a steering wheel 26.

Dans sa partie centrale, le châssis 10 comporte un fond 27 sur lequel reposent deux roues de la machine de battage ainsi que des moyens 28 de blocage de cette machine, qui ne sont représentés que schématiquement et sont bien connus dans la technique. Ces moyens peuvent par exemple comprendre des cales coulissantes 28a qui coopèrent avec les roues de la machine de battage pour maintenir cette dernière dans une position déterminée, centrée par rapport à un repère 29, et des patins de blocage 28b assurant le blocage des cales et des roues dans ladite position centrée par rapport au châssis. La machine de battage repose par ailleurs sur le sol par l'intermédiaire d'une troisième roue visible sur les schémas des figures 10 et 14 et qui est donc située en dehors du chariot 10, du côté opposé à celui sur lequel les poteaux doivent être battus.In its central part, the frame 10 comprises a bottom 27 on which rest two wheels of the threshing machine and 28 locking means of this machine, which are shown only schematically and are well known in the art. These means may for example comprise sliding wedges 28a which cooperate with the wheels of the threshing machine to maintain the latter in a determined position, centered with respect to a mark 29, and locking pads 28b ensuring the blocking of the wedges and wheels in said centered position relative to the frame. The threshing machine also rests on the ground via a third wheel visible on the diagrams of the figures 10 and 14 and which is therefore located outside the carriage 10, on the side opposite to that on which the posts must be beaten.

A l'avant de l'engin, l'ensemble 22 de commande et de direction porte une tige 30 sensiblement horizontale, qui peut être démontée et fixée au choix soit sur le côté gauche, soit sur le côté droit du chariot et qui porte un manchon 32 dont la position le long de la tige 30 ainsi que la position angulaire peuvent être réglées et fixées, ce manchon étant lui-même solidaire d'une tige 34 servant de pointeau et d'organe de guidage de l'engin le long d'un tracé au sol prédéterminé.At the front of the machine, the control and steering assembly 22 carries a substantially horizontal rod 30, which can be disassembled and fixed to either the left or the right side of the carriage and which carries a sleeve 32 whose position along the rod 30 and the angular position can be adjusted and fixed, this sleeve itself being secured to a rod 34 serving as a needle and guiding member of the machine along the a predetermined ground layout.

Les longerons 14 du châssis 10 comportent deux paires de logements traversants alignés 36, associées chacune à un moyen de blocage qui peut être constitué par exemple, comme représenté aux dessins, par au moins une vis 38 coopérant avec un écrou 40 fixé par exemple par soudage sur au moins un des longerons (Figures 3 et 4). Les logements 36 peuvent aussi être délimités par des manchons fixés sur les deux longerons 14 et faisant partie du châssis 10.The longitudinal members 14 of the frame 10 comprise two pairs of aligned through housings 36, each associated with a locking means which may consist, for example, as represented in the drawings, by at least one screw 38 cooperating with a nut 40 fixed for example by welding on at least one of the longitudinal members ( Figures 3 and 4 ). The housings 36 may also be delimited by sleeves fixed on the two longitudinal members 14 and forming part of the frame 10.

La partie B de l'engin comprend, dans le mode de réalisation représenté aux figures 5 et 6, deux poutres 50, 52 articulées l'une sur l'autre autour d'un axe sensiblement vertical 54. La poutre 50 comporte des moyens lui permettant d'être montée et fixée de façon réglable sur la partie A de l'engin.Part B of the machine comprises, in the embodiment shown in Figures 5 and 6 , two beams 50, 52 hinged to one another about a substantially vertical axis 54. The beam 50 comprises means allowing it to be mounted and fixed in an adjustable manner on the part A of the machine.

A cet effet, la poutre 50 porte deux bras 56 de section appropriée, carrée, rectangulaire, en U ou autre. Leur écartement et leurs dimensions leur permettent de pouvoir s'engager simultanément et avec un jeu très faible dans les logements ou manchons 36 ménagés à cet effet dans les longerons du chariot 10. Les logements ou manchons peuvent être équipés de roulements pour faciliter l'engagement et le mouvement des bras 56.For this purpose, the beam 50 carries two arms 56 of appropriate section, square, rectangular, U or other. Their spacing and their dimensions allow them to be able to engage simultaneously and with very little clearance in the housings or sleeves 36 formed for this purpose in the longitudinal members of the carriage 10. The housings or sleeves may be equipped with bearings to facilitate engagement and the movement of the arms 56.

Cette première poutre 50 de la partie B porte un mécanisme de butée qui sera décrit ci-dessous à propos des figures 7 à 9.This first beam 50 of part B carries a stop mechanism which will be described below about Figures 7 to 9 .

Le deuxième élément constituant la partie B comprend une poutre longitudinale 52, articulée sur la première autour de l'axe 54. Cette poutre 52 porte une roue non-motrice 58 dont l'axe est disposé sensiblement dans le plan horizontal médian de la poutre 52, et dont la surface de roulement est, dans sa partie basse, sensiblement alignée avec la surface de roulement des roues du chariot 10.The second element constituting the part B comprises a longitudinal beam 52 articulated on the first about the axis 54. This beam 52 carries a non-driving wheel 58 whose axis is disposed substantially in the median horizontal plane of the beam 52 , and whose running surface is, in its lower part, substantially aligned with the rolling surface of the wheels of the carriage 10.

La poutre 52 porte deux mécanismes de butée, identiques à celui prévu sur la poutre 50 et que l'on va décrire maintenant plus en détail (figures 7 à 9).The beam 52 carries two stop mechanisms, identical to that provided on the beam 50 and which will now be described in more detail ( Figures 7 to 9 ).

Dans le mode de réalisation représenté, chaque mécanisme de butée 60 est porté par une platine support 62 par exemple à section en U fixée sur la poutre 50 ou 52 par tous moyens convenables tels que des boulons 64, ou autres.In the embodiment shown, each stop mechanism 60 is carried by a support plate 62 for example U-section fixed on the beam 50 or 52 by any suitable means such as bolts 64, or other.

Un corps de vérin 66 est fixé sur cette platine au moyen de pattes 67, 69 et d'ensembles boulon-écrou 71. La tige mobile 68 de ce vérin porte à son extrémité libre une pièce 70 de forme générale parallélépipédique, qui est guidée en translation dans une glissière 72 de la platine et sur laquelle une butée 74 est fixée au moyen d'un boulon 75 constituant un axe sensiblement vertical autour duquel cette butée peut pivoter. La butée 74 a une forme générale en coin dont une face 76 est destinée à coopérer avec un poteau P déjà en place et dont l'autre face 78, inclinée par rapport à la première, est destinée à coopérer avec une rampe 80 délimitée sur une cale 82 dont la position par rapport à la platine 62 est de préférence réglable, par exemple au moyen d'un dispositif à lumière 84, boulon 86 et écrou 88 permettant de bloquer cette cale dans la position appropriée choisie. La cale 82 délimite une surface d'appui 82a pour la butée 74, en position active de cette dernière.A cylinder body 66 is fixed to this plate by means of tabs 67, 69 and nut-bolt assemblies 71. The movable rod 68 of this jack carries at its free end a part 70 of generally parallelepipedal shape, which is guided by translation in a slide 72 of the plate and on which a stop 74 is fixed by means of a bolt 75 constituting a substantially vertical axis around which this stop can rotate. The abutment 74 has a generally wedge shape, one face 76 of which is intended to cooperate with a post P already in place and whose other face 78, inclined with respect to the first, is intended to cooperate with a ramp 80 delimited on a wedge 82 whose position relative to the plate 62 is preferably adjustable, for example by means of a light device 84, bolt 86 and nut 88 for locking this wedge in the appropriate position chosen. The shim 82 delimits a bearing surface 82a for the abutment 74, in the active position of the latter.

De préférence, un ressort de rappel 90 est disposé entre les faces en regard de la pièce 70 et de la cale 82, ce ressort agissant pour repousser la tige de vérin et la butée 74 vers la position effacée représentée à la figure 8.Preferably, a return spring 90 is disposed between the facing faces of the piece 70 and the shim 82, this spring acting to push the cylinder rod and the stop 74 to the erased position shown in FIG. figure 8 .

Chacun des vérins 66 est relié à une alimentation en air comprimé fourni par le compresseur via le kit moteur pneumatique 18 et sous le contrôle d'organes de commande appropriés 92, 93 disposés sur le poste de commande. Ces divers conduits d'alimentation sont bien connus et n'ont pas été représentés.Each of the cylinders 66 is connected to a supply of compressed air supplied by the compressor via the pneumatic motor kit 18 and under the control of appropriate control members 92, 93 arranged on the control station. These various supply ducts are well known and have not been shown.

Cet ensemble est complété par une tige 94 montée coulissante dans des anneaux de guidage 96 prévus sur la poutre 50 ou sur les deux poutres 50, 52 (figures 5 et 6). Cette tige comporte une partie principale 94a, prolongée à sa partie arrière par une portion coudée comportant une partie 94b sensiblement verticale et une partie 94c sensiblement horizontale destinée à coopérer avec des orifices 95 ménagés dans les poteaux (figure 1).This assembly is completed by a rod 94 slidably mounted in guide rings 96 provided on the beam 50 or on the two beams 50, 52 ( Figures 5 and 6 ). This rod comprises a main portion 94a, extended at its rear portion by a bent portion having a substantially vertical portion 94b and a substantially horizontal portion 94c intended to cooperate with orifices 95 formed in the posts ( figure 1 ).

La poutre 50 porte par ailleurs un repère 98 au moyen duquel l'utilisateur peut s'assurer que le prochain poteau sera bien battu à son emplacement correct. La tige 98 a une longueur égale à celle de la distance devant séparer deux poteaux adjacents, augmentée de la distance entre les positions qu'occupent le long du tracé les repères 29 et 98.The beam 50 also carries a mark 98 by means of which the user can make sure that the next post will be well beaten at its correct location. The rod 98 has a length equal to that of the distance to separate two poles adjacent, increased by the distance between the positions occupied along the route by the markings 29 and 98.

On va maintenant décrire dans deux applications différentes le fonctionnement de cet engin et de la machine de battage qui lui est associée, en se référant respectivement aux figures 10 à 13 puis aux figures 14 à 17.We will now describe in two different applications the operation of this machine and the threshing machine associated with it, respectively referring to Figures 10 to 13 then to Figures 14 to 17 .

La première application (figures 10 à 13) correspond à un chantier « de création » pour lequel le bas-côté de la voie de circulation ne comporte pas initialement de glissières. II faut donc mettre en place les poteaux successifs suivant un tracé prédéterminé et fixer sur ces poteaux les éléments de glissières de sécurité.The first application ( Figures 10 to 13 ) corresponds to a "creation" site for which the aisle side of the taxiway does not initially include slides. It is therefore necessary to set up the successive poles along a predetermined path and to fix on these poles the elements of guardrails.

On supposera que les éléments de glissière ont une longueur de quatre mètres mais le fonctionnement serait bien entendu le même avec des tronçons de glissière de deux mètres de long mais en utilisant alors le mécanisme de butée 60 situé à deux mètres de l'axe de la machine de battage, matérialisé par le repère 29, au lieu d'utiliser, comme représenté aux dessins, le mécanisme de butée situé à quatre mètres de ce même repère 29.It will be assumed that the slide elements have a length of four meters but the operation would of course be the same with slide sections two meters long but then using the stop mechanism 60 located two meters from the axis of the slide. threshing machine, materialized by the mark 29, instead of using, as shown in the drawings, the stop mechanism located four meters from the same mark 29.

Toutes les connexions pneumatiques utiles ayant été réalisées avec le compresseur, l'utilisateur doit tout d'abord positionner l'engin par rapport aux marquages au sol qui ont été précédemment effectués suivant un tracé T.Since all the useful pneumatic connections have been made with the compressor, the user must first position the machine in relation to the ground markings that have previously been made according to a T-plot.

A cet effet, l'utilisateur déplace la partie A de l'engin pour la disposer parallèlement à ce marquage, puis il aligne le pointeau 34 sur ce même marquage au sol et le bloque dans une position de référence qui lui permettra ensuite de suivre ce marquage.For this purpose, the user moves part A of the machine to arrange it parallel to this marking, then he aligns the needle 34 on the same ground marking and blocks it in a reference position which will then allow him to follow this marking.

L'utilisateur amène ensuite la partie B de l'engin dans une position correcte correspondant à l'emplacement du premier poteau P1 qui servira ensuite de référence. Il règle la position de la deuxième partie B de l'engin par rapport à la première A en faisant coulisser la partie B jusqu'à l'emplacement du premier poteau et en positionnant en conséquence les bras 56 dans les logements ou manchons 36 puis en bloquant ces bras dans la position choisie au moyen des vis 38.The user then brings part B of the machine into a correct position corresponding to the location of the first pole P1 which will then serve as a reference. It adjusts the position of the second part B of the machine relative to the first A by sliding the part B to the location of the first post and positioning accordingly the arms 56 in the housings or sleeves 36 and then blocking these arms in the chosen position by means of screws 38.

Une fois la partie B bloquée, le premier poteau est battu.Once part B is blocked, the first post is beaten.

Ces réglages étant effectués et le premier poteau battu, l'utilisateur place la butée 74 en position sortie ou active (figure 7) en commandant l'alimentation du vérin 66 et fait avancer l'engin (figure 10) en suivant le marquage au sol T, jusqu'à ce que la butée 74 vienne en contact avec le poteau P1 (figure 11). L'opérateur arrête l'engin. La machine de battage est alors en principe en position correcte pour assurer le battage du poteau suivant P2.These adjustments being made and the first pole beaten, the user places the stop 74 in the extended or active position ( figure 7 ) by controlling the supply of the jack 66 and advancing the machine ( figure 10 ) following the ground marking T, until the stop 74 comes into contact with the pole P1 ( figure 11 ). The operator stop the machine. The threshing machine is then in principle in the correct position to ensure the threshing of the post P2 next.

Cette opération étant effectuée, l'utilisateur actionne l'organe de commande 92 du vérin 66 pour couper l'alimentation en air, de telle sorte que l'organe de butée 74 puisse pivoter vers sa position effacée (figure 12) à la fois par frottement contre le poteau P1, lors de l'avancement de l'engin, et sous l'effet du ressort de rappel 90.This operation being performed, the user actuates the control member 92 of the jack 66 to cut off the air supply, so that the stop member 74 can pivot to its erased position ( figure 12 ) both by friction against the pole P1, during the advancement of the machine, and under the effect of the return spring 90.

Comme représenté à la figure 12, l'utilisateur fait avancer l'engin toujours en suivant le tracé au sol T. Il agit à nouveau sur l'organe 92 de commande de l'alimentation du vérin 66, pour replacer le mécanisme de butée en position active (figure 13), revenant ainsi à l'étape du processus représentée à la figure 10.As represented in figure 12 , the user advances the machine always following the track on the ground T. It acts again on the control member 92 of the actuator of the jack 66, to replace the stop mechanism in the active position ( figure 13 ), thus returning to the stage of the process represented in figure 10 .

Par un souci de précision, l'utilisateur peut aussi utiliser la tige 94 pour s'assurer que l'engin est correctement positionné par rapport au dernier poteau battu. Pour cela, l'un des ouvriers qui se tient à l'arrière de l'engin et qui assure ensuite la fixation de la glissière sur les poteaux, engage l'extrémité arrière de la tige 94 dans l'orifice 95 prévu à cet effet dans le poteau. L'opérateur disposé à la partie avant de l'engin peut alors s'assurer que l'extrémité avant de la tige 94 ou bien un repère porté par cette tige se trouve bien en face du repère 98 prévu sur la poutre 50.For the sake of precision, the user can also use the rod 94 to ensure that the machine is correctly positioned relative to the last pole beaten. For this, one of the workers who stands at the rear of the machine and who then ensures the fixing of the slide on the posts, engages the rear end of the rod 94 in the hole 95 provided for this purpose in the pole. The operator disposed at the front part of the machine can then ensure that the front end of the rod 94 or a mark carried by this rod is well in front of the mark 98 provided on the beam 50.

Dans la deuxième application qui correspond à un deuxième type de chantier dit « de rechargement », des glissières de sécurité existent déjà mais elles doivent être rehaussées, du fait du rechargement de la chaussée.In the second application which corresponds to a second type of building site called "reloading", safety rails already exist but they must be raised, because of the reloading of the roadway.

Il faut alors dans ce cas démonter les glissières, les poser au sol, rebattre les poteaux, fixer une réhausse sur chaque poteau puis refixer les éléments de glissière. Dans cette application, on n'utilise que la poutre 50 de la partie B de l'engin, la poutre 52 étant par conséquent démontée et stockée par exemple dans un camion.It is then necessary in this case to disassemble the slides, lay them on the ground, reshuffle the posts, fix a riser on each post and then reattach the slide elements. In this application, only the beam 50 of the part B of the machine is used, the beam 52 being consequently disassembled and stored for example in a truck.

Un premier réglage est effectué pour positionner correctement l'engin par rapport aux poteaux existants. Pour cela, on peut tendre un fil F entre deux poteaux adjacents P1 et P2 et positionner l'engin parallèlement à ce fil. L'utilisateur déplace l'engin et peut aligner le pointeau 34 sur ce fil qui remplace le marquage au sol. Il peut aussi, le cas échéant se dispenser de cet alignement et déplacer ensuite l'engin d'un poteau au poteau suivant.A first adjustment is made to correctly position the machine relative to existing poles. For this, one can stretch a wire F between two adjacent posts P1 and P2 and position the machine parallel to this wire. The user moves the machine and can align the needle 34 on the wire that replaces the ground marking. He may also, if necessary, dispense with this alignment and then move the machine from one pole to the next.

La séquence de fonctionnement est ensuite très proche de ce qui a été décrit à propos des figures 10 à 13. L'utilisateur place la butée 74 en position active (figure 14) puis déplace l'engin vers l'avant jusqu'à ce que cette butée vienne en contact avec le poteau P1 (figure 15). La position de la partie B par rapport à la partie A est éventuellement réglée et fixée, l'opération de battage a lieu et l'utilisateur commande ensuite le vérin du mécanisme de butée pour amener la butée 74 en position effacée (figure 16) et il fait alors avancer l'engin en direction du poteau suivant P2, se ramenant ainsi à l'étape du processus représentée à la figure 17, qui correspond à celle de la figure 14, mais pour le poteau suivant.The sequence of operation is then very close to what has been described about Figures 10 to 13 . The user places the stop 74 in the active position ( figure 14 ) then moves the machine forward until this stop comes into contact with the pole P1 ( figure 15 ). The position of the part B with respect to the part A is possibly adjusted and fixed, the threshing operation takes place and the user then controls the cylinder of the stop mechanism to bring the stop 74 to the erased position ( figure 16 ) and it then moves the machine towards the next post P2, thus returning to the process step represented at figure 17 , which corresponds to that of the figure 14 but for the next post.

On a supposé dans ce qui précède que le marteau de la machine de battage M se trouvait sur le côté droit de l'engin mais la machine de battage peut être disposée de telle façon que le marteau se trouve sur le côté gauche de l'engin, auquel cas la deuxième partie B de ce même engin est elle-même montée sur le côté gauche du chariot A, les mécanismes de butée portés par les platines étant alors eux-mêmes disposés sur les longerons de gauche des poutres 50 et 52 tandis que le dispositif de guidage va se trouver sur le côté droit de l'engin.It was assumed in the above that the hammer of the threshing machine M was on the right side of the machine but the threshing machine can be arranged in such a way that the hammer is on the left side of the machine , in which case the second part B of the same machine is itself mounted on the left side of the carriage A, the stop mechanisms carried by the plates then themselves being arranged on the left side members of the beams 50 and 52 while the guiding device will be on the right side of the machine.

On peut aussi prévoir que le débattement sous les poutres 50 et 52 soit suffisant pour que le dispositif puisse fonctionner sans avoir à démonter et remonter les mécanismes de butée, les butées proprement dites 74 se trouvant alors au dessous des poutres 52 et non au-dessus lorsque la position de la partie B est inversée.It is also possible that the clearance under the beams 50 and 52 is sufficient for the device to operate without having to disassemble and reassemble the stop mechanisms, the stops proper 74 then being below the beams 52 and not above when the position of part B is reversed.

Lorsque l'engin est en position de transport, la poutre 52 peut être repliée le long de la poutre 50 et l'ensemble de la partie B maintenu sur la partie A par tout moyen convenable, par exemple au moins une sangle.When the machine is in the transport position, the beam 52 can be folded along the beam 50 and all of the part B maintained on the part A by any suitable means, for example at least one strap.

De nombreuses variantes peuvent être apportées à un engin selon l'invention sans pour autant sortir de son cadre : à tire d'exemple, les rôles du vérin 66 et du ressort 98 pourraient être inversés, le vérin étant utilisé pour rétracter la butée 74 vers sa position effacée, tandis qu'un ressort solliciterait cette butée vers sa position active.Many variants can be made to a machine according to the invention without departing from its scope: for example, the roles of the cylinder 66 and the spring 98 could be reversed, the cylinder being used to retract the abutment 74 to its erased position, while a spring would solicit this stop to its active position.

II résulte de ce qui précède que l'engin selon l'invention permet effectivement d'obtenir les résultats souhaités :

  • il permet d'utiliser une machine de battage classique qui est la mieux adaptée pour effectuer ce type de travail, que les glissières et autres barrières de sécurité soient réalisées en métal ou en bois ;
  • il permet de se dispenser complètement du chemin de roulement utilisé dans l'art antérieur, ce qui supprime de ce fait les inconvénients liés à la mise en place et à la reprise des éléments de glissière avec lesquels sont habituellement réalisés les chemins de roulement ;
  • les moyens de guidage utilisés sont très simples tout en étant efficaces ;
  • l'engin lui-même est de construction simple et robuste, d'un prix de revient particulièrement raisonnable et d'une utilisation très simple ne nécessitant pas un personnel très qualifié.
It follows from the foregoing that the machine according to the invention actually makes it possible to obtain the desired results:
  • it makes it possible to use a conventional threshing machine that is best suited to perform this type of work, whether the slides and other safety barriers are made of metal or wood;
  • it makes it possible to dispense completely with the raceway used in the prior art, which thus eliminates the drawbacks associated with the introduction and the recovery of the slide elements with which the raceways are usually made;
  • the guide means used are very simple while being effective;
  • the machine itself is simple and robust construction, a particularly reasonable cost and a very simple use not requiring highly qualified personnel.
