Abstract

The cage (1) is used to house snails during battery-rearing and breeding by amateurs or for research. It differs in detail for rearing and breeding having a floor (4) which slopes towards a drain channel (17) at the front. Parallel vertical side walls (3) of an approximately oval shape extend from the floor, the roof (2) and the rear wall (B) following an externally convex curve. The front door (5) is bottom hung (6) and catches a closure, with an aperture (8) for the introduction of food. Slits (S) in the door and the rear wall provide ventilation, and a revolving water jet (12) sweeps the internal surfaces. The channel may have a perforated cover and the rear cage may have a rectangular floor opening, locating a laying-box.

Description

DESCRIPTION 1. La présente invention concerne un nouveau type de cage d'élevage des escarçots, destiné à la production intensive, répondant aux impératifs des deux phases de cet élevage : la phase reproduction et la phase croissance. Dans les dispositifs, procédés ou batteries d'élevage connus (Brevets n 2 426 408 A1 du 26 mai 1978, n 2 451 160 A1 du 16 mars 1979 et n 2 450 561 A1 du 8 mars 1979), les matériels étaient conçus de façon empirique et présentaient des angles morts, imnosant un nettoyage manuel difficile, et entrainant des pertes importantes d'effectif, en raison de l'impossibIlité d'assurer à l'intérieur des éléments, un état sanitaire satisfaisant
Dans la plupart des cas, la conception des éléments imposait l'utilisation d'une barrière anti-fuite électrique, d'un fonctionnement aléatoire et nécessitant une surveillance quasi-permanente des animaux et du dispositif. Les divers avantages du procédé et matériel, objet du présent brevet, seront développés plus abondamment au cours de la description et des revendications suivantes. Les deux variante (cage variante reproduction et cage variante croissance) sont con #ues exactement sur le même plan de base dont les caractéristiques sont les suivantes.
DESCRIPTION 1. The present invention relates to a new type of snail breeding cage, intended for intensive production, meeting the requirements of the two phases of this breeding: the reproduction phase and the growth phase. In the known devices, methods or batteries for farming (Patents n 2 426 408 A1 of May 26, 1978, n 2 451 160 A1 of March 16, 1979 and n 2 450 561 A1 of March 8, 1979), the materials were designed so empirical and presented blind spots, implying a difficult manual cleaning, and causing significant losses of manpower, due to the impossibility of ensuring inside the elements, a satisfactory sanitary state
In most cases, the design of the elements required the use of an electric anti-leak barrier, of random operation and requiring almost permanent monitoring of the animals and the device. The various advantages of the process and material, object of this patent, will be developed more abundantly during the description and the following claims. The two variants (reproduction variant cage and growth variant cage) are designed exactly on the same basic plane, the characteristics of which are as follows.

2. L'élément de base de l'ensemble est une cellule (Fig 1 variante croissance ; Fig 2 variante reproduction) délimitée : par deux plans verticaux correspondant aux faces latérales 1, un plan oblique correspondant à la porte 5, un plan incliné, en prolongement du chaineau 17, correspondant au plancher et formant un angle de cuelcues degrés par rapport à l'horizontale, la partie ainsi délimitée par ces 4 plans ayant une forme ovotide (Fig 1, 2 et 9). 2. The basic element of the assembly is a cell (Fig 1 growth variant; Fig 2 reproduction variant) delimited: by two vertical planes corresponding to the lateral faces 1, an oblique plane corresponding to the door 5, an inclined plane, as an extension of the chain 17, corresponding to the floor and forming an angle of cuelcues degrees relative to the horizontal, the part thus delimited by these 4 planes having an ovotid shape (Fig 1, 2 and 9).

3. La cellule de base est close et ne comporte avec l'extérieur que deux types de communications : des fentes 3 (cf paragraphe 4) et un passage 4 dans chacune des deux parois latérales. Ces passages revetent ceux formes (FIG 3 et FIG 6), la surface des passages est marquée de pointillés sur les schémas.3. The base cell is closed and has only two types of communication with the outside: slots 3 (see paragraph 4) and a passage 4 in each of the two side walls. These passages cover those formed (FIG 3 and FIG 6), the surface of the passages is marked with dotted lines in the diagrams.

4 , La cellule de base comporte une porte d ' d'accès (5 FIG 1 et 2), (FIG 3), dont la carrière (E FIG 1, FIG 3) permet une ouverture de plus de 180 suivant le sens de rotation indiqué par la flèche (7 KG 1 et 2 et FIG 3).  4, The basic cell has an access door (5 FIG 1 and 2), (FIG 3), the career (E FIG 1, FIG 3) allows an opening of more than 180 depending on the direction of rotation indicated by the arrow (7 KG 1 and 2 and FIG 3).

Cette porte d'accès s comporte u diaphragme E (FIG 1 et 2) permet- tant l'approvisionnement en nourriture (pistolet doseur) sans ouverture de la porte. La porte est tenue fermée par deux fermetures (9 FIG 3) ; la forme de celles-ci permet une fermeture de la pore par simple poussée. Cette porte est percée d'un nombre suffisant de fentes 3, permettant une bonne aération de 1 ensemble et évitant la fuite des animau jeunes et adultes. This access door has a diaphragm E (FIG 1 and 2) allowing the supply of food (dosing gun) without opening the door. The door is held closed by two closures (9 FIG 3); the shape of these allows the pore to be closed by a simple push. This door is pierced with a sufficient number of slots 3, allowing good ventilation of 1 set and preventing the escape of young and adult animals.

5. La face courbe de la cellule de base opposée à la porte comporte également un certain nombre de fentes (3 FIG 1 et FIG 2) ; l'aération du volume Intérieur de la cellule de base a lieu grâce au courant d'airs'établissant entre les fentes 3 de la porte et la face courbe oppose à ia porte.5. The curved face of the base cell opposite the door also has a certain number of slots (3 FIG 1 and FIG 2); the interior volume of the base cell is ventilated by means of the air flow between the slots 3 of the door and the curved face opposite the door.

6. Chaque cellule de base est munie d'un dispositif d'injection d'eau. Ce dispositif comporte successivement un axe d'alimentation 10 (FIG 1 et 2, FIG 3, FIG 7, FIG 8, FIG 9, FIG 10, FIG 11) un raccord 11 (FIG 3 et FIG 11) perpendiculaire à l'axe, une buse 12 (FIG 1 et 2, Fi 3, FIG 11) dans le prolongement du raccord. La buse est un cylindre de laiton (FIG 11) percé dans son axe d'un trou 13 (8/10è à 20/10è mm de # par exemple) ; le trou débouche sur une fente 14 en biseau dont l'angle x par rapport à l'axe du cylindre est de 1J0 à 60 .Dans cet ensemble, l'eau chemine de la manière suivante (FIG 11) : île arrive par l'axe 10, passe par le raccord 11, emprunte le trou axial 13 de la buse 12 dont elle sort par l'ouverture en biseau 14.6. Each basic cell is equipped with a water injection device. This device successively comprises a supply axis 10 (FIG 1 and 2, FIG 3, FIG 7, FIG 8, FIG 9, FIG 10, FIG 11) a connector 11 (FIG 3 and FIG 11) perpendicular to the axis, a nozzle 12 (FIG 1 and 2, Fi 3, FIG 11) in the extension of the connector. The nozzle is a brass cylinder (FIG 11) pierced in its axis with a hole 13 (8/10 to 20/10 mm # for example); the hole leads to a beveled slot 14 whose angle x with respect to the axis of the cylinder is from 1J0 to 60. In this assembly, the water travels as follows (FIG 11): the island arrives by the axis 10, passes through the connector 11, borrows the axial hole 13 of the nozzle 12 from which it leaves through the bevel opening 14.

7. Le fonctionnement du dispositif d'injection d'eau est le suivant
Les caractéristiques de la buse déterminent la forme de la nappe d'eau : n1, n2, n3, n4 (FIG 1) ; les parois internes de la cellule comprises entre ces points sont donc arrosées par la nappe ainsi définie. L'axe 10 est affecté d'un mouvement de rotation entrainant raccord et buse dans un mouvement circulaire dont le sens est indiqué par la flèche 15 (FIG 3). Ce mouvement circulaire est transmis G la nappe d'eau qui effectue un travail de balayage des parois suivant le sens 16 (FIG 1 et FIG 3).L'eau est évacuée par un chaineaud 17 (FIG 1, FIG 2, FIG 3, FIG 4, FIG 5, FIG 7,
FIG 8) et sort de la cellule par le passage 4 (cf paragraphe 3) dont le rôle est de permettre cette évacuation de l'eau et des déjections.
7. The operation of the water injection device is as follows
The characteristics of the nozzle determine the shape of the water table: n1, n2, n3, n4 (FIG 1); the internal walls of the cell lying between these points are therefore watered by the sheet thus defined. The axis 10 is affected by a rotational movement causing the fitting and the nozzle in a circular movement, the direction of which is indicated by the arrow 15 (FIG 3). This circular movement is transmitted to the water table which performs a work of scanning the walls in the direction 16 (FIG 1 and FIG 3). The water is evacuated by a chain 17 (FIG 1, FIG 2, FIG 3, FIG 4, FIG 5, FIG 7,
FIG 8) and leaves the cell through passage 4 (see paragraph 3) whose role is to allow this evacuation of water and excrement.

8. Ce système d'évacuation de l'eau et des déjections est muni d'un dispositif évitant la sortie des animaux (dispositif antifuite). 8. This system for evacuating water and excrement is provided with a device preventing the exit of animals (anti-leakage device).

Ce dispositif peut être de deux types : Type 1 et type 2.This device can be of two types: Type 1 and type 2.

Type 1 : Le chatneau 17 est coiffé d'un chatneau identique mais retourné 18 (FIG 3, FIG 4). Le carneau 18 est disposé sur le chatneau 17 de manière à ménager une fente 19 (FIG 3, FIG 4) dont la hauteur peut être réglée (cales) de 1 mm à plusieurs mm. Type 1: The chateau 17 is capped with an identical but turned 18 chateau (FIG 3, FIG 4). The flue 18 is arranged on the chateau 17 so as to provide a slot 19 (FIG 3, FIG 4) whose height can be adjusted (shims) from 1 mm to several mm.

Cette fente 19 permet le' passage des eaux usées mais interdit celui des animaux. Ces derniers n'ont pas accès au chatneau 17 et par là même au passage 4.This slot 19 allows the passage of wastewater but prohibits that of animals. The latter do not have access to chateau 17 and therefore to passage 4.

Type 2 : Le chatneau 17 est coiffé d'une plaque 20 (FIG 4, FIG 6) percée de trous de diamètre variable (2 mm à 8 mm) ou de fentes de différentes largeurs. Cette plaque peut éventuellement être surmontée d'un grillage fin. Ces trous permettent le passage de l'eau vers le carneau 17 mais interdisent celui des animaux.Type 2: The chateau 17 is capped with a plate 20 (FIG 4, FIG 6) pierced with holes of variable diameter (2 mm to 8 mm) or slots of different widths. This plate can possibly be surmounted by a fine mesh. These holes allow the passage of water to the flue 17 but prohibit that of animals.

Comme dans le cas précédent, ceux-ci ne peuvent accéder au chatneau 17 et sortir par le passage 4 (FIG 4, FIG 6).As in the previous case, they cannot access the chateau 17 and exit through passage 4 (FIG 4, FIG 6).

9. Les caractéristiques propres des 2 variantes sont les suivantes. 9. The specific characteristics of the 2 variants are as follows.

La variante croissance répond exactement au descriptif ci-dessus (paragraphe 1 à 8). La variante reproduction en diffère par les éléments suivants.The growth variant corresponds exactly to the description above (paragraphs 1 to 8). The reproduction variant differs in the following elements.

a) Le plancher de la cellule comporte un évidemment rectanulnaire 21 (FIG 2) de 23.6 cm x 10.4 cm (par exemple). Cet évidemment reçoit un pondoir (22 - FIG 5, FIG 8) ; lorsque le pondoir est en place ses rebords ne s' appliquent pas directement sur le plancher de la cellule car ils en demeurent distants d'environ 1 cm, (FIG 3). Ce pondoir reçoit le substrat de ponte. a) The floor of the cell has a rectangular opening 21 (FIG 2) of 23.6 cm x 10.4 cm (for example). This obviously receives a nesting box (22 - FIG 5, FIG 8); when the nest box is in place its edges do not apply directly to the floor of the cell because they remain about 1 cm apart (FIG 3). This nest receives the laying substrate.

b) Ce pondoir est coiffé d'un élément analogue 23 (FIG 5 et
FIG 8) dans lequel des ouvertures sont aménagées (faces latérales et antérieures de 23). Cet élément 23 protège le substrat de ponte placé en 22 de la nappe d'arrosage et ses ouvertures permettent aux animaux d'atteindre le substrat de ponte.
b) This nest is capped with a similar element 23 (FIG 5 and
FIG 8) in which openings are arranged (lateral and anterior faces of 23). This element 23 protects the laying substrate placed at 22 from the water table and its openings allow animals to reach the laying substrate.

c) En plus des passages 4 (of paragraphe 3) existant dans la variante croissance, dans la cellule variante reproduction, les parois latérales cl portent des ouvertures circulaires 24 (FIG 2,
FIG 3). Les caractéristiques des ouvertures sont les suivantes
- Concentriques par rapport à l'axe d'arrosage et permettant de laisser passer les animaux adultes.
c) In addition to the passages 4 (of paragraph 3) existing in the growth variant, in the reproduction variant cell, the side walls cl carry circular openings 24 (FIG 2,
FIG 3). The characteristics of the openings are as follows
- Concentric with respect to the watering axis and allowing adult animals to pass.

10. Far suite de modifications d'une mise en oeuvre aisée, les cages variante reproduction peuvent être utilisées pour la croissance de la manière suivante - Obturation des évidemment s 21 destinés à recevoir les pondoirs et des passages 24, à l'aide de plaques amovibles de polypropy- lène. 10. Far following modifications of an easy implementation, the breeding variant cages can be used for the growth in the following way - Obturation of the obviously s 21 intended to receive the nesting boxes and passages 24, using plates removable polypropylene.

11. Ces batteries sont composées, par exemple et de façon non limitative (FIG 7, FIG 8) : - de 4 rangs horizontaux superposés de 10 cellules contigus, soit 40 cellules au total.11. These batteries are composed, for example and without limitation (FIG 7, FIG 8): - of 4 horizontal rows superimposed with 10 contiguous cells, ie 40 cells in total.

Chaque cellule pouvant avoir dans sa forme ovotide :
46.5 cm de long sur 31 cm de hauteur et 20 cm de large
La batterie pouvant avoir les dimensions suivantes
Hauteur 1.70 m
Longueur 2.00 m
Frofondeur 0.50 m
Les axes d'alimentation 10 (FIG 1, FIG 2, FIG 3, FIG 7, FIG 8, FIG 9,
FIG 10, FIG 11) pouvant avoir un diamètre intérieur de 8 à 10 mm, les raccords et buses une hauteur de 10 à 70 mm.
Each cell can have in its ovotid form:
46.5 cm long by 31 cm high and 20 cm wide
The battery can have the following dimensions
Height 1.70 m
Length 2.00 m
Depth 0.50 m
The feed axes 10 (FIG 1, FIG 2, FIG 3, FIG 7, FIG 8, FIG 9,
FIG 10, FIG 11) can have an internal diameter of 8 to 10 mm, the fittings and nozzles a height of 10 to 70 mm.

12. Les 40 cellules de la batterie ont un fonctionnement synchrone du dispositif d'injection d'eau, pour les raisons suivantes. L'axe 10 est commun pour les 10 cellules contiguës : Chaque batterie comporte donc 4 axes superposés (FIG 7, FIG 8, FIG 10). Le mouvement de rotation des 4 axes est assuré par une turbine à eau unique 25 (FIG 7, FIG 8, FIG 10) dont le rôle est également d'amener l'eau dans les 4 axes par l'intermédiaire d'une colonne montante 26 (FIG 7, FIG 8, FIG 10). L'eau est ensuite recueillie dans le chatneau 17 unique pour un groupe de 10 cellule contiguës.Le chatneau conduit cette eau (à travers les passages 4 des cellules précédemment décrites : cf paragraphe 3) à une colonne descendante 27 (FTC- 7, F-:G 8, FIG a). L'eau des 4 chatneaux superposés est recueillie par cette unique colonne descendante.12. The 40 cells of the battery operate synchronously with the water injection device, for the following reasons. The axis 10 is common for the 10 contiguous cells: Each battery therefore has 4 superimposed axes (FIG 7, FIG 8, FIG 10). The rotary movement of the 4 axes is ensured by a single water turbine 25 (FIG 7, FIG 8, FIG 10), the role of which is also to bring the water into the 4 axes via a riser 26 (FIG 7, FIG 8, FIG 10). The water is then collected in the single chateau 17 for a group of 10 contiguous cells. The chateau leads this water (through the passages 4 of the cells previously described: see paragraph 3) to a down column 27 (FTC- 7, F -: G 8, FIG a). The water from the 4 superimposed chateaux is collected by this single descending column.

13. La batterie variante reproduction diffère de la variante croissance par l'existence des passages précédemment décrits (cf paragraphe 9 c). Ces passages permettent la circulation des animaux d'une cellule à l'autre. Les 10 cellules d'un même rang horizontal ne communiquent pas toutes entre elles car certaines cloisons verticales sont dépourvues de communication. Les cellules sont par exemple ainsi réparties en 3 groupes de cellules communiquant entre elles (groupe 32, 33, 34 - groupe 35, 36, 37, 38 - groupe 39, 40, 41 FIG 8). 13. The reproduction variant battery differs from the growth variant by the existence of the passages previously described (see paragraph 9 c). These passages allow the movement of animals from one cell to another. The 10 cells of the same horizontal row do not all communicate with each other because some vertical partitions are devoid of communication. The cells are for example thus distributed into 3 groups of cells communicating with each other (group 32, 33, 34 - group 35, 36, 37, 38 - group 39, 40, 41 FIG 8).

flans ces groupes, les cellules 33, 3E, 37, 40 (FIG 8) sont dépourvues de pondoirs.  In these groups, cells 33, 3E, 37, 40 (FIG 8) are devoid of nesting boxes.
