Description

La présente invention est relative à un dispositif tracté pour le ramassage de paillage sous forme de film plastique utilisé notamment en agriculture.The present invention relates to a towed device for collecting mulch in the form of plastic film used in particular in agriculture.

On sait qu'aprés récolte, l'agriculteur qui a-utilisé un paillage sous forme de film plastique doit retirer ce dernier pour pouvoir travailler à nouveau le sol sans le saturer d'éléments indestructibles, ce retrait s'effectue manuellement ce qui présente le désavantage d'être laborieux et malaisé car le film plastique ramassé en vrac est volumineux, d'autre part il supporte mal le vieillissement qui est accéléré durant son exposition à tous les temps le rendant cassant.We know that after harvesting, the farmer who has used a mulch in the form of plastic film must remove the latter to be able to work the soil again without saturating it with indestructible elements, this removal is done manually which presents the disadvantage of being laborious and awkward because the plastic film picked up in bulk is bulky, on the other hand it does not tolerate aging which is accelerated during its exposure at all times making it brittle.

L'invention a pour but de pallier aux inconvénients précédemment exposés.The invention aims to overcome the drawbacks described above.

L'invention a pour objet un dispositif tracté de ramassage de paillage sous forme de film plastique s'adaptant à l'attelage trois-points d'un tracteur, ledit dispositif comportant un chassis reposant au sol par l'intermédiaire de deux roues et sur lequel est maintenu entre les longerons un tambour cylindrique rotatif à l'intérieur duquel sont contenues des séries de doigts disposés en étoile et répartis sur sa largeur, lesdites séries étant solidaires d'un arbre maintenu à l'intérieur dudit tambour de manière désaxée de telle sorte que, durant la rotation du tambour à l'inverse de la rotation des roues provoquée au moyen d'une transmission à chaine par exemple, lesdits doigts dirigés et passant au travers de la surface latérale du tambour soient saillants à l'aplomb du sol afin d'enfourcher le film plastique pour l'entrainer durant la rotation du tambour à l'arrière du dispositif où un enrouleur est aménagé, le film plastique au niveau de l'enrouleur étant désemparé des doigts grâce à leur retrait de la surface latérale du tambour.The subject of the invention is a towed device for collecting mulch in the form of a plastic film adapting to the three-point hitch of a tractor, said device comprising a chassis resting on the ground by means of two wheels and on which is held between the longitudinal members a rotary cylindrical drum inside which are contained series of fingers arranged in a star and distributed over its width, said series being integral with a shaft maintained inside said drum in an offset manner such so that, during the rotation of the drum contrary to the rotation of the wheels caused by means of a chain transmission for example, said fingers directed and passing through the lateral surface of the drum are protruding above the ground in order to get on the plastic film to drive it during the rotation of the drum at the rear of the device where a reel is fitted, the plastic film at the reel being free of fingers due to their withdrawal from the lateral surface of the drum.

D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre faite en regard des dessins joints donnés à titre d'exemple non limitatif, où - la figure 1 est une vue de côté du dispositif, - la figure 2, une vue de dessus du dispositif, - la figure 3, une vue en coupe transversale du tambour.Other characteristics and advantages of the invention will emerge more clearly from the description which follows, given with reference to the accompanying drawings given by way of nonlimiting example, where - Figure 1 is a side view of the device, - Figure 2, a top view of the device, - Figure 3, a cross-sectional view of the drum.

- la figure 4, une vue en coupe longitudinale du tambour.- Figure 4, a longitudinal sectional view of the drum.

Tel que représenté figures 1 à 4, le dispositif de ramassage comporte un chassis 1 doté de longerons 2 reliés à l'avant par une traverse 3 sur laquelle sont aménagés les ancrages 4 pour l'attelage trois-points d'un tracteur, sous les longerons 2 sont fixées les roues 5 reposant au sol et un tambour cylindrique rotatif 6 dont la surface latérale 7 est dotée d'évidements 8 prolongés intérieurement par des conduits 9 servant de guides à des doigts 10 coulissant dans lesdits conduits 9, les doigts 10 étant répartis en étoile et solidaires d'un manchon 11 rotatif enfilé sur un arbre 12, ce dernier est maintenu en ses extrémités sur des flasques 13 prolongeant à l'intérieur du tambour les axes 14 reliés aux longerons 2 par des paliers 15 et sur lesquels sont maintenus les côtés 16 du tambour 6 au moyen de roulements ou paliers 17, l'arbre 12 par rapport à l'axe du tambour et/ou des axes 14 est maintenu de manière décalé afin de constituer un excentrique entre les doigts 10 et la surface latérale 7 du tambour 6 et notamment pour que les doigts 10 orientés vers le sol durant la rotation du tambour 6 soient saillants pour pénétrer et enfourcher le film plastique 18 afin de l'entra1her vers l'arrière du chassis 1 où un enrouleur 19 à courroies 28 est aménagé pour récupérer ledit film durant le déplacement du dispositif, les doigts 10 opposés aux doigts saillants orientés vers le sol étant en retrait par rapport à la surface latérale 7 du tambour 6 de manière à désemparer le film plastique 18 pour permettre son enroulement, la position en retrait et saillante des doigts 10 s'effectuant progressivement durant la rotation du tambour 6.La rotation du tambour 6 est obtenue au moyen d'une transmission par chaume 20 tendue entre des pignons 21, 22, 23 et 24 solidaire d'une des roues 5, du tambour 6 et d'un longeron 2, elle s'effectue de manière inverse à celle des roues 5 et le rapport des pignons est tel qu'il provoque durant ia rotation une longueur développée du tambour 6 identique à la longueur développée des roues 5 de sorte à avoir un ramassage constant et linéaire du film plastique 18 durant le déplacement du dispositif.As shown in FIGS. 1 to 4, the pickup device comprises a chassis 1 provided with side members 2 connected at the front by a cross-member 3 on which the anchors 4 are arranged for the three-point hitch of a tractor, under the longitudinal members 2 are fixed the wheels 5 resting on the ground and a rotary cylindrical drum 6 whose lateral surface 7 is provided with recesses 8 extended internally by conduits 9 serving as guides for fingers 10 sliding in said conduits 9, the fingers 10 being distributed in a star and integral with a rotary sleeve 11 threaded on a shaft 12, the latter is held at its ends on flanges 13 extending inside the drum the axes 14 connected to the side members 2 by bearings 15 and on which are maintained on the sides 16 of the drum 6 by means of bearings or bearings 17, the shaft 12 with respect to the axis of the drum and / or of the axes 14 is held offset so as to constitute an eccentric between the es fingers 10 and the lateral surface 7 of the drum 6 and in particular so that the fingers 10 oriented towards the ground during the rotation of the drum 6 are protruding to penetrate and straddle the plastic film 18 in order to entrain it towards the rear of the chassis 1 where a reel 19 with belts 28 is arranged to recover said film during the movement of the device, the fingers 10 opposite the projecting fingers pointing towards the ground being set back with respect to the lateral surface 7 of the drum 6 so as to loosen the plastic film 18 to allow it to be wound up, the recessed and projecting position of the fingers 10 taking place progressively during the rotation of the drum 6.The rotation of the drum 6 is obtained by means of a thatched transmission 20 stretched between pinions 21, 22, 23 and 24 secured to one of the wheels 5, the drum 6 and a side member 2, it is carried out in reverse to that of the wheels 5 and the ratio of the pinions is such that it causes during ia rotation a developed length of the drum 6 identical to the developed length of the wheels 5 so as to have a constant and linear collection of the plastic film 18 during the movement of the device.

Le film 18 récupéré et désemparé des doigts 10, en la partie arrière du chassis 1, est enroulé sur un arbre rotatif 25, celui-ci en ses extrémités 26 est solidaire de bras articulés 27 sur les longerons 2 du chassis 1, la rotation de l'arbre 25 et de ce fait l'enroulement du film plastique 18 autour dudit arbre 25 est obtenu au moyen de l'enrouleur 19 doté de courroies 28 tendues sur des arbres rotatifs 29 dont l'un, L'arbre 29a, est entravé par une transmission à channe 30 entravée elle-même par la rotation de la transmission 20.The film 18 recovered and clueless from the fingers 10, in the rear part of the chassis 1, is wound on a rotary shaft 25, the latter at its ends 26 is secured to articulated arms 27 on the side members 2 of the chassis 1, the rotation of the shaft 25 and therefore the winding of the plastic film 18 around said shaft 25 is obtained by means of the reel 19 provided with belts 28 tensioned on rotary shafts 29 one of which, the shaft 29a, is hampered by a chain transmission 30 hindered itself by the rotation of the transmission 20.

Afin d'éviter le bourrage en cas de rupture du film 18 entre le tambour 6 et l'enrouleur 19, un déflecteur 31 est maintenu sur un arbre rotatif 32, son extrémité 33 parallèle à la surface latérale du tambour 6 s'appuyant au fur et à mesure de la rotation du tambour 6 sur ses génératrices ce qui a pour effet de nettoyer la surface latérale 7 dudit tambour (6).  In order to avoid jamming in the event of the film 18 breaking between the drum 6 and the reel 19, a deflector 31 is maintained on a rotary shaft 32, its end 33 parallel to the lateral surface of the drum 6 being supported as and as the drum 6 rotates on its generatrices which has the effect of cleaning the lateral surface 7 of said drum (6).
