Description

- La présente invention concerne un dispositif pour brasser et aérer, dans la même opération, le contenu d'un composteur. Cette opération de brassage-aération, effectuée régulièrement est indispensable au bon fonctionnement d'un composteur. Elle apporte l'oxygène nécessaire aux organismes vivants chargés de dégrader la matière et assure l'homogénéité, sans compactage, des 2 types de matériaux dédiés au composteur : les déchets azotés et les déchets carbonés. Le brassage assure aussi la régulation entre matériaux secs et matériaux humides. Aujourd'hui, l'aération peut être effectuée à l'aide d'une tige portant à ses extrémités une partie recourbée ou des ailettes rétractables. L'opération est longue et discontinue ; elle n'affecte que l'endroit du piquage de la tige. Elle ne produit pas un brassage des matériaux. Le brassage complet ne peut être réalisé qu'en procédant à un retournement à la fourche légère, soit sur une bâche avec retour dans le même composteur, soit vers un deuxième composteur proche. Cette opération n'est entreprise que trop rarement, pour cause de pénibilité de l'investissement physique associé, ce qui est très préjudiciable au bon fonctionnement du composteur. Le dispositif selon l'invention permet de remédier à ces inconvénients. Tl se compose, selon une première caractéristique, d'un hélicoïde en fil rond et lisse en acier à ressort. La pointe de l'extrémité libre de cet hélicoïde est taillée en tronc de cône, ce qui lui permet de pénétrer aisément dans les matériaux habituels d'un composteur par un simple mouvement de vissage. La première spire a un pas moindre, afin de bien enserrer les matériaux à extraire. L'autre extrémité est constituée d'une spire de type "rapprochée". Elle forme la "poignée volant". L'opérateur y exerce le mouvement de vissage pour faire pénétrer l'outil à la profondeur adaptée à sa capacité physique à extraire, par un mouvement de traction vertical, une "carotte" de matériaux emprisonnés dans les spires. Quelques secousses éparpillent cette "carotte" à l'endroit souhaité du composteur. L'opération, reprise en un nombre limité d'endroits, conduit à un retournement complet des matériaux à l'intérieur même du composteur, assurant à la fois le brassage et l'aération. Le dispositif peut se décliner en plusieurs versions selon la taille du composteur et l'origine manuelle ou mécanique de la force disponible pour l'opération. The present invention relates to a device for stirring and aerating, in the same operation, the contents of a composter. This brewing-aeration operation, performed regularly is essential to the proper functioning of a composter. It provides the oxygen necessary for living organisms responsible for degrading the material and ensures the homogeneity, without compaction, of the 2 types of material dedicated to the composter: nitrogenous waste and carbonaceous waste. The brewing also ensures the regulation between dry materials and wet materials. Today, the aeration can be performed using a rod carrying at its ends a bent portion or retractable fins. The operation is long and discontinuous; it only affects the location of the stitching of the stem. It does not produce a mix of materials. Complete brewing can only be achieved by reversing to the light fork, either on a sheet with return in the same composter, or to a second close composter. This operation is undertaken only too rarely, because of the difficulty of the associated physical investment, which is very detrimental to the proper functioning of the composter. The device according to the invention overcomes these disadvantages. T1 is composed, according to a first characteristic, of a helicoid round wire and smooth steel spring. The tip of the free end of this helicoid is cut into a truncated cone, which allows it to easily penetrate the usual materials of a composter by a simple screwing movement. The first turn has a smaller step, in order to properly grip the materials to extract. The other end consists of a "close-up" type turn. It forms the "flying handle". The operator exercises the screwing movement to penetrate the tool to the depth adapted to its physical capacity to extract, by a vertical traction movement, a "carrot" of materials trapped in the turns. A few shakes scatter this "carrot" at the desired place of the composter. The operation, taken in a limited number of places, leads to a complete reversal of the materials inside the composter, ensuring both mixing and aeration. The device can be divided into several versions depending on the size of the composter and the manual or mechanical origin of the force available for the operation.

Dans sa version domestique, pour le brassage d'un composteur individuel, le fil lisse en acier à ressort a un diamètre de l'ordre de 8 mm, pour constituer un hélicoïde dont le diamètre des spires est de l'ordre de 200 mm et la longueur totale de l'ordre de 750 mm. Cette longueur totale reste inférieure à la profondeur des composteurs standards afin que l'outil puisse y rester à demeure, vissé dans le compost. A la visite suivante, sa tige en acier -2- peut donner une indication précieuse sur la température interne du compost et son degré d'humidité. Le pas de la spire d'attaque est de l'ordre de 90 mm. Les autres spires ont un pas plus important, de l'ordre de 160 mm. Pour le confort de l'opérateur, la "poignée-volant" peut être équipée d'une gaine ergonomique. Une sphère d'un diamètre d'environ 50 mm, en matériau souple, percée suivant un axe à un diamètre légèrement inférieur au diamètre du fil des spires, est engagée sur ce fil jusqu'à la poignée-volant. Il permet à l'opérateur de nettoyer éventuellement le fil des spires après usage, par glissement progressif de cette sphère vers l'extrémité libre de l'outil. Un traitement anti-corrosion pourra être appliqué au fil en acier pour le cas où l'outil séjournerait dans le composteur. In its domestic version, for the brewing of an individual composter, the spring steel smooth wire has a diameter of about 8 mm, to form a helicoid whose diameter of turns is of the order of 200 mm and the total length of the order of 750 mm. This total length is less than the depth of the standard composters so that the tool can remain there permanently, screwed into the compost. At the next visit, its steel rod -2- can give a valuable indication of the internal temperature of the compost and its degree of humidity. The pitch of the turn of attack is of the order of 90 mm. The other turns have a larger step, of the order of 160 mm. For the comfort of the operator, the "flywheel" can be equipped with an ergonomic sheath. A sphere with a diameter of about 50 mm, made of flexible material, pierced along an axis at a diameter slightly smaller than the diameter of the wire of the turns, is engaged on this wire to the handle-flywheel. It allows the operator to possibly clean the thread of the turns after use, by progressive sliding of this sphere towards the free end of the tool. An anti-corrosion treatment may be applied to the steel wire in case the tool remains in the composter.

Dans sa version collective ou semi-industrielle, pour le brassage mécanique d'un composteur de plus grande taille, le dispositif reste identique mais les caractéristiques de l'hélicoïde sont adaptées aux performances souhaitées et aux capacités de la machine destinée à produire le mouvement de vissage, le mouvement de traction verticale, puis le mouvement d'éparpillement des matériaux extraits. La "poignée-volant" conserve son rôle de zone d'application de l'énergie mécanique utilisée par la machine. La présence de la sphère de nettoyage n'est pas indispensable sur ce grand modèle, pas plus que la gaine. Le dessin annexé présente une vue en perspective du dispositif, objet de l'invention. En référence à ce dessin, le dispositif se compose d'un hélicoïde (1), formé dans un fil rond et lisse en acier ressort, d'un seul tenant. L'une des extrémités (2) est taillée en pointe tronconique. L'autre extrémité (3) est une spire "rapprochée" formant une poignée-volant pouvant être habillée d'une gaine ergonomique. La première spire (4), côté pointe tronconique (2), a un pas réduit par rapport aux autres spires (5) afin de bien enserrer la base de la carotte de matériaux à extraire. Une petite sphère (6) en matériau souple, coulisse sur le fil de l'hélicoïde, à frottement doux, pour le nettoyage. In its collective or semi-industrial version, for the mechanical mixing of a larger composter, the device remains identical but the characteristics of the helicoid are adapted to the desired performances and the capacities of the machine intended to produce the movement of screwing, vertical pulling motion, then the scattering motion of the extracted material. The "flying handle" retains its role as a zone of application of the mechanical energy used by the machine. The presence of the cleaning sphere is not essential on this large model, any more than the sheath. The attached drawing shows a perspective view of the device object of the invention. With reference to this drawing, the device consists of a helicoid (1), formed in a round wire and smooth steel spring, in one piece. One of the ends (2) is cut into a frustoconical point. The other end (3) is a "close" turn forming a flying handle that can be dressed with an ergonomic sheath. The first turn (4), tapered tip side (2), has a reduced pitch relative to the other turns (5) to properly grip the core of the core material to extract. A small sphere (6) of flexible material, slides on the wire of the helicoid, with soft friction, for cleaning.

Les cotes du dispositif doivent être adaptées aux dimensions des composteurs pour lesquels cet outil de brassage-aération est destiné. A titre d'exemple non limitatif, pour un composteur domestique standard de 400 litres, le fil en acier ressort aura un diamètre de 8 mm. Les spires, un diamètre extérieur de 200 mm. La spire d'attaque aura un pas de 90 mm contre un pas de 160 mm pour les 4 spires suivantes. La longueur totale de l'outil sera, alors d'environ 750 mm. Le diamètre de la sphère de nettoyage sera d'environ 50 mm, pour une bonne prise en main. Le dispositif selon l'invention est particulièrement destiné au brassage, incluant aération, des matériaux à l'intérieur même d'un composteur individuel ou collectif. The dimensions of the device must be adapted to the dimensions of the composters for which this mixing-aeration tool is intended. By way of non-limiting example, for a standard domestic composter of 400 liters, the spring steel wire will have a diameter of 8 mm. The turns, an outer diameter of 200 mm. The turn of attack will have a pitch of 90 mm against a pitch of 160 mm for the next 4 turns. The total length of the tool will be, then about 750 mm. The diameter of the cleaning sphere will be about 50 mm, for a good grip. The device according to the invention is particularly intended for mixing, including aeration, materials inside a single or collective composter.
