Art antérieurPrior art

Le nettoyage des déchets urbains ou industriels peut s'effectuer à l'aide d'aspirateurs tractés. Il arrive fréquemment que des végétaux de faible hauteur, tels des petites pousses ou des mousses, colonisent les zones urbaines extérieures. Ces petits végétaux étant enracinés, ils ne peuvent pas être aspirés. Il est alors nécessaire, après ou avant le nettoyage par aspiration, de procéder au désherbage de ces zones. Il s'ensuit une perte de temps et souvent l'obligation d'acquérir un autre dispositif spécifiquement dédié au désherbage.Cleaning of urban or industrial waste can be done using towed vacuum cleaners. It often happens that low plants, such as small shoots or moss, colonize outdoor urban areas. These small plants being rooted, they cannot be vacuumed. It is then necessary, after or before vacuum cleaning, to weed these areas. This results in a waste of time and often the obligation to acquire another device specifically dedicated to weeding.

The nozzle 33 comprises gripping means 331 which are able to cooperate with the operator's forearm and with the latter's hand, like a crutch. The free end of the nozzle 33 is equipped with a support wheel 332 which allows it to be held on the ground and made to roll in order to facilitate the use of the device of the invention.

En référence à la Fig. 1, le socle 1 comporte une plateforme 13 sur laquelle peut se tenir un opérateur. A l'avant de la plateforme 13 se trouve une portion verticale de protection 15, perpendiculaire au socle 1. Les deux roues directionnelles 12 sont couplées au timon 7 qui permet de contrôler leur rotation autour d'un axe vertical par rapport au socle 1. Le timon 7 est également articulé en rotation autour d'un axe horizontal parallèle à la largeur du dispositif. Le timon 7 peut être amené dans une position verticale telle que représentée sur la Fig. 1 ou dans une position sensiblement horizontale qui permet de tracter le socle 1. Dans sa position verticale, le timon 7 est clipsé sur la portion de protection 15 au niveau de moyens de blocage 152. Des moyens de rappel 153, ici formés par un vérin, permettent de ramener le timon 7 dans sa position verticale et de le bloquer dans les moyens de blocage 152. L'extrémité libre 71 du timon 7 comporte les moyens de commande 73 du moteur du socle 1. Le bras de désherbage 9 est monté de manière amovible à côté des roues directionnelles avant 12.In reference to the Fig. 1 , the base 1 includes a platform 13 on which an operator can stand. At the front of the platform 13 is a vertical protective portion 15, perpendicular to the base 1. The two directional wheels 12 are coupled to the drawbar 7 which makes it possible to control their rotation around a vertical axis by relative to the base 1. The drawbar 7 is also articulated in rotation around a horizontal axis parallel to the width of the device. The drawbar 7 can be brought into a vertical position as shown on the Fig. 1 or in a substantially horizontal position which allows the base 1 to be towed. In its vertical position, the drawbar 7 is clipped onto the protective portion 15 at the level of blocking means 152. Return means 153, here formed by a jack, make it possible to return the drawbar 7 to its vertical position and to block it in the blocking means 152. The free end 71 of the drawbar 7 comprises the control means 73 of the motor of the base 1. The weeding arm 9 is mounted so removable next to the front directional wheels 12.

Le bras de désherbage 9 va être décrit plus en détails en référence au Fig. 1 et 2.The weeding arm 9 will be described in more detail with reference to Fig. 1 and 2 .

La bras de désherbage 9 comporte une brosse rotative 91, laquelle comporte une touffe de filaments 912. Les filaments sont dans le cas présent des câbles d'acier aptes à désherber/déchirer/déraciner des végétaux de faible hauteur, du type nouvelles pousses ou mousses. Le bras de désherbage 9 s'étend au-delà du socle 1 selon la direction du mouvement du dispositif. Une extrémité du bras de désherbage 9 est montée coulissante sur un tube (non référencé) faisant office de rail et solidaire du socle 1. Une molette de fixation (non représentée) permet de fixer le bras de désherbage sur ce tube par frottements de l'extrémité de la tige filetée de la molette sur le tube formant rail. En référence à la Fig. 2, le bras de désherbage 9 comporte une portion rectiligne 92 qui se prolonge par un tube de fixation 921, lequel dépasse dans la direction opposée à la brosse 91. Ce tube 921 vient s'emmancher dans le tube formant rail qui équipe le socle 1. Le bras de désherbage 9 comporte également un manchon de connexion 93 sensiblement vertical, disposé à proximité de la touffe de filaments 912. Ce manchon de connexion 93 est apte à être connecté avec l'extrémité libre du tuyau 31, une fois que celui-ci est retiré de la buse 33. Un moteur électrique rotatif 95 est disposé sur le bras 9 et couplé à la brosse 91. Il comporte ses propres moyens de commande et permet d'entrainer la brosse 91 en rotation. Il comporte également un variateur de vitesse qui permet de choisir la vitesse de rotation de la brosse 91. Le manchon d'aspiration 93 et la brosse 91 forme un ensemble solidaire qui est monté à rotation sur la portion rectiligne 92 au niveau d'un axe de rotation (non référencé) horizontal et parallèle à la largeur du socle 1. Un vérin 96 relie le bloc formé par la brosse 91, son moteur 95 et le manchon de connexion 93 et permet l'articulation de ce dernier autour de l'axe précité entre une position d'utilisation dans laquelle les extrémité de filaments de la touffe 912 sont à proximité voire en contact avec le sol (le bras de désherbage est alors rectiligne) et une position de repos dans laquelle, la brosse 91 est pivotée et les poils sont éloignés du sol, ne gênant pas ainsi la progression du dispositif de l'invention. Le vérin 96 est un vérin électrique ; il est connecté à l'alimentation du moteur de la brosse 95. Il comporte un interrupteur qui permet de l'actionner de façon à relever la brosse.The weeding arm 9 includes a rotating brush 91, which includes a tuft of filaments 912. The filaments are in this case steel cables capable of weeding/tearing/uprooting low plants, such as new shoots or moss. . The weeding arm 9 extends beyond the base 1 according to the direction of movement of the device. One end of the weeding arm 9 is slidably mounted on a tube (not referenced) acting as a rail and secured to the base 1. A fixing wheel (not shown) allows the weeding arm to be fixed on this tube by friction of the end of the threaded rod of the wheel on the tube forming the rail. In reference to the Fig. 2 , the weeding arm 9 comprises a rectilinear portion 92 which is extended by a fixing tube 921, which protrudes in the direction opposite to the brush 91. This tube 921 fits into the tube forming a rail which equips the base 1. The weeding arm 9 also comprises a substantially vertical connection sleeve 93, arranged near the tuft of filaments 912. This connection sleeve 93 is capable of being connected with the free end of the pipe 31, once the latter is removed from the nozzle 33. A rotary electric motor 95 is placed on the arm 9 and coupled to the brush 91. It has its own control means and makes it possible to drive the brush 91 in rotation. It also includes a speed variator which makes it possible to choose the rotation speed of the brush 91. The suction sleeve 93 and the brush 91 form an integral assembly which is mounted to rotate on the rectilinear portion 92 at the level of an axis of rotation (not referenced) horizontal and parallel to the width of the base 1. A jack 96 connects the block formed by the brush 91, its motor 95 and the connection sleeve 93 and allows the articulation of the latter around the axis aforementioned between a position of use in which the end of filaments of the tuft 912 are close or even in contact with the ground (the weeding arm is then straight) and a rest position in which the brush 91 is pivoted and the hairs are away from the ground, thus not disturbing the progression of the device of the invention. The cylinder 96 is an electric cylinder; it is connected to the power supply of the brush motor 95. It includes a switch which allows it to be activated so as to raise the brush.

Toujours en référence à la Fig. 2, le bras de désherbage 9 comporte des moyens de guidage des débris qui font également office de moyens de protection/isolement de la brosse 91. Ces moyens de guidage comportent une jupe élastiquement déformable 97 qui entoure partiellement la brosse 91. Cette jupe 97 forme un arc de cercle et s'étend sur au moins un diamètre de la brosse 91. Par ailleurs, l'extrémité basse du manchon de connexion 93 comporte une tête d'aspiration 98 également en matériau déformable. La tête d'aspiration 98 forme un tube qui prolonge le manchon de connexion 93 avantageusement jusqu'au sol (avantageusement jusqu'au niveau de l'extrémité libre des filaments de la brosse 91). La tête d'aspiration 98 est donc située à proximité de la touffe de filaments 912. Elle comporte dans sa partie basse en regard des filaments de la brosse 91, une échancrure d'aspiration par laquelle les débris végétaux ou autres sont aspirés. Sur la Fig. 2, la tête d'aspiration ne touche pas le sol ; il s'agit d'une variante.Still with reference to the Fig. 2 , the weeding arm 9 comprises means for guiding the debris which also act as means of protection/isolation of the brush 91. These guiding means comprise an elastically deformable skirt 97 which partially surrounds the brush 91. This skirt 97 forms a arc of a circle and extends over at least one diameter of the brush 91. Furthermore, the lower end of the connection sleeve 93 comprises a suction head 98 also made of deformable material. The suction head 98 forms a tube which extends the connection sleeve 93 advantageously to the ground (advantageously to the level of the free end of the filaments of the brush 91). The suction head 98 is therefore located near the tuft of filaments 912. It has in its lower part facing the filaments of the brush 91, a suction notch through which plant or other debris is sucked up. On the Fig. 2 , the suction head does not touch the ground; this is a variation.

Le fonctionnement du dispositif de l'invention va maintenant être décrit en référence aux Fig. 1 et 2.The operation of the device of the invention will now be described with reference to the Fig. 1 and 2 .

Lorsque l'opérateur nettoie une zone par aspiration, le bras de désherbage 9 peut être retiré ou non du socle 1. S'il est monté sur le dispositif, il est mis en position de repos. Le tuyau 31 est connecté à la buse 33 et l'opérateur peut ainsi aspirer les déchets ou autres situés sur la zone à nettoyer. S'il s'avère que la zone doit également être désherbée, l'opérateur monte le bras de désherbage 9, si ce dernier n'est pas déjà monté sur le socle 1. Il déconnecte la buse 32 et relie l'extrémité du tuyau 31 au manchon 33, plus précisément à l'extrémité supérieure de ce dernier. Il actionne ensuite le vérin 96 afin de faire pivoter le manchon 93 et la brosse 91 dans la position d'utilisation représentée sur les Fig. 1 et 2.When the operator cleans an area by suction, the weeding arm 9 may or may not be removed from the base 1. If it is mounted on the device, it is placed in the rest position. The pipe 31 is connected to the nozzle 33 and the operator can thus vacuum up waste or others located in the area to be cleaned. If it turns out that the area also needs to be weeded, the operator mounts the weeding arm 9, if the latter is not already mounted on the base 1. He disconnects the nozzle 32 and connects the end of the pipe 31 to the sleeve 33, more precisely at the upper end of the latter. It then activates the cylinder 96 in order to pivot the sleeve 93 and the brush 91 into the position of use shown on the Fig. 1 and 2 .

L'opérateur actionne alors le moteur 95 afin de mettre en rotation la brosse 91. De préférence, il se positionne sur la plateforme 13 et dirige et fait avancer le dispositif grâce au timon 7 équipé des moyens de commande du moteur du socle. Le timon 7 est dans sa position verticale. L'opérateur amène le dispositif de l'invention sur les zones à désherber. La brosse 91 arrache les végétaux et désincruste la terre ou tout autre substrat. Les débris ainsi formés sont aspirés par la tête d'aspiration 98, au niveau de son échancrure. La jupe 97 guide les débris vers la tête d'aspiration 98. Cette dernière en raclant le sol arrête les débris et facilite leur aspiration en les plaçant juste sous le manchon 93.The operator then activates the motor 95 in order to rotate the brush 91. Preferably, he positions himself on the platform 13 and directs and advances the device using the drawbar 7 equipped with means for controlling the base motor. Drawbar 7 is in its vertical position. The operator brings the device of the invention onto the areas to be weeded. Brush 91 pulls up plants and removes dirt or any other substrate. The debris thus formed is sucked up by the suction head 98, at the level of its notch. The skirt 97 guides the debris towards the suction head 98. The latter, by scraping the ground, stops the debris and facilitates their suction by placing them just under the sleeve 93.
