Abstract
Description
La presente Invention concerne un dispositif utilisable manuellement pour semer simultanément plusieurs graines une a une dans tous types de godets mottes terrines etc.. The present invention relates to a device which can be used manually for simultaneously sowing several seeds one by one in all types of clods, etc.
Les semis de ce genre sont realises par des machines automatiques ou à l'aide du semoir manuel ayant fait l'objet d'une demande de brevet n 9609771 dont la puissance ne permet de semer des graines trop lourdes en nombre suffisant. Sowing of this kind is carried out by automatic machines or using the manual seeder which was the subject of a patent application No. 9609771 whose power does not allow sowing seeds too heavy in sufficient number.
le dispositif selon l'invention offre une solution simple, économique, et remédie aux inconvenients du semoir manuel cité ci-dessus. the device according to the invention offers a simple, economical solution, and remedies the drawbacks of the manual seed drill mentioned above.
I1 comporte selon ce qui le caracterise dans les revendications une griffe de semis surmonte d'une tuyre dans laquelle est introduit un injecteur relie a une source d'air comprime équipée d'un système ouverture- fermeture le tout de structure creuse , forme un ensemble rigide manuellement utilisable. I1 comprises, according to what characterizes it in the claims, a seed claw surmounted by a nozzle into which is injected an injector connected to a source of compressed air equipped with an opening-closing system, the whole of hollow structure, forms an assembly rigid manually usable.
La griffe se compose d'un tube porteur ferme a ses extremites, greffe d'un ou plusieurs tubes preneurs dont les etremités libres sont de forme tronc-coniques et perces en lueur axe. The claw consists of a closed support tube at its ends, graft of one or more grab tubes whose free ends are truncated-conical and pierced in an axis glow.
La tuyère est faite d'un tube qui par une extrémité reçoit l'injecteur et par l'autre en forme de convergent laisse echapper l'air envoyé par la pointe de l'injecteur, elle est fixée sur le t.ube porteur de maniere a ce que l'injecteur puisse y être facilement introduit. La jonction entre l'intérieur creux du tube porteur et de la tuyère se fait par un orifice débouchant dans la tuyère en arrière de la pointe de l'injecteur et de manière à ce que l'air circule librement du convergent de la tuyère par l'intérieur du dispositif aux extrémités libres des tubes preneurs. The nozzle is made of a tube which by one end receives the injector and by the other in the form of convergent lets escape the air sent by the point of the injector, it is fixed on the t.ube carrying way so that the injector can be easily inserted there. The junction between the hollow interior of the carrier tube and the nozzle is made by an orifice opening into the nozzle behind the tip of the injector and so that the air circulates freely from the convergent of the nozzle through the inside the device at the free ends of the pick-up tubes.
L'assemblage extrémité tuyère injecteur est étanche. The injector nozzle end assembly is tight.
L'injecteur est une buse effilée qui lorsqu'elle est positionnée dans la tuyere se trouve dans l'axe du convergent de cette tuyère par lequel s'échappe l'air. The injector is a tapered nozzle which when positioned in the nozzle is located in the axis of the convergent of this nozzle through which the air escapes.
L'injecteur est monté à la sortie d'un système ouverturefermeture relie par un tube souple à un compresseur d'air ce système est muni d'une poignée qui permet de tenir 1' ensemble d'une seule main ,d le déplacer facilement. et comme pour une "souflette" d'ouvrir et de fermer le passage d'air en pressant ou non sur une gâchette. Lorsque l'air passe la dépression crée en arrière de la pointe de l'injecteur dans la tuyère se transmet dans toute la griffe et provoque un phénomène d'aspiration aux extrémités libres des tubes preneurs qui peuvent ainsi prendre chacun une graine. lorsque l'air ne passe plus la depression n'existe plus les graines tenus aux extrémités des tubes preneurs tombent. The injector is mounted at the outlet of an opening-closing system connected by a flexible tube to an air compressor. This system is provided with a handle which makes it possible to hold the assembly with one hand, to move it easily. and as for a "bellows" to open and close the air passage by pressing or not on a trigger. When the air passes the depression created behind the tip of the injector in the nozzle is transmitted throughout the claw and causes a phenomenon of aspiration at the free ends of the pick-up tubes which can thus each take a seed. when the air no longer passes the depression no longer exists the seeds held at the ends of the pick-up tubes fall.
Selon des modes particuliers de réalisation
-la poiqnee du système ouverture-fermeture peut être orientable par rapport a la griffe en pivotant autour de l'axe de la tuyère.According to particular embodiments
-the poiqnee of the opening-closing system can be adjustable relative to the claw by pivoting around the axis of the nozzle.
-1' injecteur peut ête interchangeable de manière à offrir plusieurs diamètres de buses d'où des forces d'aspiration différentes. -1 injector can be interchangeable so as to offer several nozzle diameters where different suction forces.
-l'injecteur peut être éloigné du système ouverturefermeture, leur jonction se fait alors par un tub souple. -the injector can be moved away from the opening-closing system, their junction is then made by a flexible tub.
-le montage d'une palette escamotable en bout de tuyère permet lorsqu'elle est positionnée face à l'éjè-ction de supprimer la dépression à l'intérieur de l'appareil et provoque un souffle à l'extrémité des tubes preneurs.-the mounting of a retractable pallet at the end of the nozzle allows when it is positioned facing the ejection to remove the vacuum inside the device and causes blowing at the end of the pick-up tubes.
-les extrémités des tubes preneurs de forme tronc-conique peuvent être coiffées de buses interchangeables offrant ansi une grande diversité de perçages et de formes, permettant de prendre toutes les graines existantes -la tuyére peut être une extrémité du tube porteur, que l'injecteur doit alors traverser de part en part de manière à ce que toutes les liaisons de ce tube avec les tubes preneurs soient en arrière de la pointe d'injection et que l'air circule librement des extrémités des preneurs à la sortie de la tuyère. -the ends of the truncated-conical tubes can be capped with interchangeable nozzles thus offering a wide variety of holes and shapes, allowing to take all the existing seeds -the nozzle can be one end of the carrier tube, than the injector must then pass right through so that all the connections of this tube with the pick-up tubes are behind the injection tip and that air circulates freely from the ends of the pick-ups to the outlet of the nozzle.
-Le tube porteur peut étre télescopique de maniere à faire varier les écartements entre les tubes preneurs et offrir ainsi une griffe modulable adaptée au alvéoles recevant les graines
