Description

Title of the invention: Collection system for collecting liquids flowing onto the floor of an enclosure for raising animals, for example cattle. Technical field of the invention

[0001] The present invention relates to the technical field of collection systems for collecting liquids flowing onto the floor of an enclosure for raising animals, for example cattle. State of the art

[0002] Animal comfort is a determining factor in the performance of a livestock operation, which notably influences the health, feed intake, fertility and longevity of the animals.

[0003] In a stable, this comfort notably implies a rapid and efficient removal of the excrement generated by the animals.

[0004] This management of excrement should in fact make it possible to reduce gas emissions and the proliferation of bacteria in the breeding facility, and consequently to improve environmental conditions and sanitary performance.

[0005] These droppings are also likely to make the ground slippery, with the resulting risks of falls and injuries.

[0006] Several waste disposal systems coexist today: mechanical disposal systems and grating systems, in particular.

[0007] In the context of a "mechanical evacuation" solution, the excrement present on the ground is scraped once or several times a day by a scraping device called a scraper (operated by a tractor or by automatic means), to be brought to a collection pit located outside the livestock building.

[0008] Another solution is to equip the animal traffic areas (waiting areas, exercise corridors, etc.) with a slatted floor (generally made of prefabricated concrete slabs).

[0009] However, in these systems, the separation of urine and feces is not optimal, or even non-existent, thus constituting an important source of ammonia.

[0010] Moreover, the installation of such an evacuation system involves significant major construction work, which is difficult to envisage in an existing livestock enclosure.

[0011] There is therefore a need for technical solutions enabling a reduction of soil moisture in livestock enclosures, advantageously without requiring major construction work, so as to improve the conditions of adhesion and the sanitary conditions of the animals.

[0012] There is also an interest in simple solutions that allow some separation of urine and feces, so as to limit the production of ammonia in livestock enclosures. Presentation of the invention

[0013] In order to remedy the aforementioned drawback of the prior art, the present invention proposes a collection system for collecting liquids flowing onto the floor of an enclosure for raising animals, for example cattle.

[0014] The collection system comprises:

[0015] (i) a floor covering consisting of a carpet, made of at least one material capable of undergoing elastic deformation, with a length, for example, between 5 m and 200 m,

[0016] which floor covering comprises:

[0017] - a base, the lower face of which is intended to rest on said ground,

[0018] - support portions, distributed on said base, on which the animals are intended to provide support, and

[0019] - grooves, separating said support portions and intended to receive liquids flowing over said floor covering,

[0020] each of which grooves are delimited by a bottom wall, corresponding to a strip of said base formed between two support portions,

[0021] which bottom wall is delimited by an upper face, forming the bottom of said groove, and by a lower face, forming a part of said lower face of the base,

[0022] which bottom wall has through-holes which open through said upper face and said lower face of said bottom wall, and

[0023] (ii) suction means, advantageously ventilation means, intended to be connected to said through orifices and adapted to generate suction of liquids through said through orifices, in the direction from the upper face to the lower face.

[0024] In practice, when the suction means are in operation, they generate a suction force which pulls the liquids through the through orifices located in the bottom wall.

[0025] These through-orifices, suitably distributed, allow an optimal flow of liquids, thus ensuring that unwanted liquids are evacuated quickly and efficiently.

[0026] The design of the suction means advantageously takes into account the specific characteristics of the liquids to be suctioned, such as viscosity and density, in order to maintain optimal performance of the collection system.

[0027] Other non-limiting and advantageous features of the product / process according to the invention, taken individually or in all technically possible combinations, are as follows:

[0028] - the grooves are straight and extend parallel to each other with respect to the others, delimiting between them a plurality of support portions, each of which has the shape of a straight strip;

[0029] - the grooves each have a width ranging from 15 to 40 mm, and a depth ranging from 5 to 25 mm, and the support portions have a width ranging from 50 to 500 mm;

[0030] - said base incorporates a reinforcing layer;

[0031] - the bottom wall has a thickness ranging from 1 to 5 mm, for example from 1 to 3mm;

[0032] - the upper face of the bottom wall is concave, for example of curved cross-section or polyhedral; the openings are provided in the middle of the width of said upper face;

[0033] - the lower face of the bottom wall is concave, for example of curved cross-section or polyhedral;

[0034] - the through orifices have a diameter ranging from 4 mm to 15 mm, preferably 5 to 10 mm.

[0035] The present invention further relates to a rearing enclosure equipped with a collection system according to the invention.

[0036] The rearing enclosure includes a circulation corridor having a longitudinal axis and the floor of which is covered by said floor covering; and the grooves of said floor covering are arranged parallel, or at least approximately parallel, with respect to said longitudinal axis.

[0037] Preferably, the floor includes conduits for the evacuation of liquids, for example selected from:

[0038] - a grating floor comprising slotted conduits, or

[0039] - a grooved floor comprising conduits in the form of longitudinal grooves, of which the The dimensions in width and depth are, for example, 1 to 5 cm.

[0040] which through orifices are provided in fluidic communication with said conduits,

[0041] which conduits are connected to the suction means, so as to generate the suction of liquids through said through orifices, via said conduits.

[0042] The present invention also relates to a method of installing a collection system according to the invention.

[0043] This process comprises the following steps:

[0044] - the laying of said floor covering on the floor and the installation of said means suction,

[0045] - drilling said through holes opposite the floor conduits, for example at using a cookie cutter.

[0046] Preferably, the suction means generate suction power. And the total surface area of ​​the orifices, advantageously defined by their diameters and their number, is adapted according to said suction power.

[0047] Of course, the various features, variants, and embodiments of the invention can be combined in various ways, provided they are not incompatible or mutually exclusive. Detailed description of the invention

[0056] It should be noted that, in these figures, the structural and / or functional elements common to the different variants may have the same references.

[0057] As schematically represented in [Fig.1], the present invention relates to a collection system 10, for collecting liquids flowing on the floor S of an enclosure E for raising animals, for example cattle.

[0058] In general, the collection system 10 comprises:

[0059] (i) a floor covering 20 consisting of a carpet, intended to rest on the floor S,

[0060] which floor covering 20 comprises through holes described below, and

[0061] (ii) suction means 30, advantageously ventilation means, intended to be connected to the through-holes and adapted to generate suction of liquids through these through-holes. Breeding pen

[0062] By "animals" we mean in particular cattle (especially dairy cows or beef cattle), pigs, or any other farm animal (sheep, poultry, rabbit, horse, etc.).

[0063] Such a livestock enclosure (not shown) consists of a building delimited by a structure, adapted to the desired livestock farming (for example a stable in the case of cattle).

[0064] At least part of the floor S of this rearing enclosure is covered by the floor covering 20 according to the invention.

[0065] In particular, the floor covering 20 is advantageously located at the level of the circulation corridors C which are used by the animals moving between the different functional spaces of the livestock enclosure (for example cubicles, milking parlors, etc.).

[0066] The traffic corridor C has a longitudinal axis (not shown), the floor S of which is covered by this floor covering 20.

[0067] Generally, the floor S includes conduits SI for the evacuation of liquids, for example chosen from:

[0068] - a grating floor S comprising slotted conduits SI (figures 1 and 5), Or

[0069] - a grooved floor S comprising conduits S1 in the form of longitudinal grooves ([Fig.7]).

[0070] By "slatted floor", we mean in particular a floor having through slots SI, the dimensions of which present a compromise between the flow of liquids and the stability of the animals.

[0071] Such a slatted floor S then forms an openwork floor, covering a pit (not shown).

[0072] Generally, the SI slots are straight, preferably with a rectangular or oblong contour. Each SI slot advantageously includes a longitudinal axis.

[0073] Each slot SI is thus advantageously delimited by:

[0074] - two long sides, defining its width and advantageously its axis longitudinal, and

[0075] - two small sides, defining its dimension in length.

[0076] The two long sides extend advantageously parallel to each other.

[0077] The two long sides extend advantageously perpendicularly to the longitudinal axis of this traffic corridor.

[0078] The SI slots advantageously have the following dimensions:

[0079] - a width of 25 to 45 mm and

[0080] - a length of 2,000 to 5,000 mm.

[0081] Preferably, the slots SI are regularly distributed on the grating floor S, forming parallel discontinuous lines.

[0082] For a grooved floor, the width and depth dimensions of the longitudinal grooves S1 are for example from 1 to 5 cm.

[0083] A grooved floor consists for example of a screed (or slab) of concrete, possibly reinforced with a metal mesh, or of bitumen.

[0084] The longitudinal channels SI are advantageously provided by grooving.

[0085] These longitudinal channels SI advantageously extend parallel to the longitudinal axis of this traffic corridor.

[0086] Generally, preferably, these conduits SI are connected to the suction means 30, so as to generate the suction of liquids through the through orifices 245, via these conduits SI.

[0087] In other words, within the framework of the present invention, the conduits SI are advantageously connected to the suction means 30, in order to create suction of liquids through through orifices 245. Flooring

[0088] The floor covering 20 is suitable for collecting liquids flowing on the floor and draining them away, so as to offer a relatively dry (or at least not excessively moist) support surface for the feet of animals, and therefore a healthier one.

[0089] By "liquids" we mean in particular the liquid excrement produced by the farm animals, in particular their urine.

[0090] Generally, preferably, the floor covering 20 has a continuous length ranging from 5 m to 200 mm.

[0091] In general, the floor covering 20 comprises:

[0092] - a base 21, the lower face 211 of which is intended to rest on the ground S,

[0093] - support portions 22, distributed on the base 21, on which the animals are intended to provide support, and

[0094] - grooves 23, separating the bearing portions 22 and intended to receive liquids flowing onto the floor covering 20.

[0095] The support portions 22 preferably have a horizontal flat surface or a convex curved surface.

[0096] For optimal grip, these support portions 22 are advantageously provided with anti-slip reliefs.

[0097] These support portions 22 may include transverse grooves 221, opening into the grooves 23, to participate in the flow of liquids ([Fig.2]).

[0098] In general, the grooves 23 are advantageously above the conduits SI made in the ground S.

[0099] These grooves 23 can:

[0100] - cross the SI conduits transversely, in particular for the grating floor, or

[0101] - longitudinally cover the SI conduits, in particular for a grooved floor.

[0102] The grooves 23 are each delimited by a bottom wall 24, corresponding to a strip of the base 21 provided between two support portions 22.

[0103] As shown in particular in Figures 3 and 4, the bottom wall 24 is delimited by two faces:

[0104] - an upper face 241, forming the bottom of the groove 23, and

[0105] - a lower face 242, forming a part of said lower face 211 of the base 21.

[0106] And this bottom wall 24 has through openings 245 which open through the upper face 241 and the lower face 242 of this bottom wall 24.

[0107] More specifically, the bottom wall 24 comprises:

[0108] - a thickness dimension, defined by the upper face 241 and by the lower face 242,

[0109] - a depth dimension, corresponding to the distance between the upper face 241 and the upper face of the support portions 22, and

[0110] - a width dimension, defined between two support portions 22.

[0111] The bottom wall 24 advantageously has a thickness (advantageously a minimum thickness at the through orifices) ranging from 1 to 5 mm, for example from 1 to 3 mm.

[0112] This reduced thickness dimension is particularly interesting for limiting the risk of clogging by solid waste.

[0113] To limit this thickness, the bottom wall 24 preferably has an upper face 241 and / or a lower face 242 which has a concave section.

[0114] According to one embodiment, the upper face 241 of the bottom wall 24 is concave (opening upwards), for example of curved section (for example in arc of a circle) or polyhedral.

[0115] By "polyhedral" we mean for example a top face comprising a central face 241a, planar or concave curve, provided between two inclined faces 241b ([Fig.3]).

[0116] The through holes 245 are preferably provided in the middle of the width of the upper face 241.

[0117] Generally speaking (particularly in a slatted floor or a grooved floor), the through holes 245 are advantageously regularly distributed.

[0118] According to one embodiment, for the different floors, strips 246, 247 without such through holes 245 contribute advantageously to the structural resistance of the floor covering 20 ([Fig.6]).

[0119] In this sense, for example, longitudinal bands 246 (along the grooves 23) and / or transverse bands 247 (perpendicular to the grooves 23) are advantageously devoid of through holes 245 ([Fig.6]).

[0120] Moreover, as illustrated in [Fig.4], the lower face 242 of the bottom wall 24 is advantageously concave (opening downwards), for example of curved section (for example in arc of a circle) or polyhedral.

[0121] By "polyhedral", we mean for example an underside having a central face formed between two vertical faces ([Fig.4]).

[0122] According to the invention, the bottom wall 24 has through orifices 245, adapted for the flow of liquids, which are advantageously distributed over its length ([Fig.2]).

[0123] For example, the through holes 245 have a diameter ranging from 4 mm to 15 mm, preferably 5 to 10 mm.

[0124] Generally, the through orifices 245 are provided in fluidic communication with the conduits SI.

[0125] Preferably, in the case of a grating floor, at least one through orifice 245 (preferably two through orifices 245) is provided in fluidic communication with a conduit SI.

[0126] Preferably, the grooves 23 are straight and extend parallel to each other, delimiting between them a plurality of bearing portions 22 which each have the shape of a straight strip.

[0127] Each groove 23 advantageously comprises a longitudinal axis; the longitudinal axes of the different grooves 23 extend parallel to each other.

[0128] Preferably, the grooves 23 are distributed over the width of the floor covering 20; and these grooves 23 extend over the entire length of the floor covering 20.

[0129] Preferably, the grooves 23 each have:

[0130] - a width ranging from 15 to 40 mm, and

[0131] - a depth ranging from 5 to 25 mm.

[0132] The support portions 22 have a width ranging from 50 to 500 mm.

[0133] Preferably, in the presence of a traffic corridor C comprising a longitudinal axis, the grooves 23 of the floor covering S 20 are arranged parallel, or at least approximately parallel, with respect to said longitudinal axis.

[0134] The floor covering 20 is advantageously made of at least one material capable of undergoing elastic deformation.

[0135] The bearing portions 22 are advantageously adapted to undergo a deformation in indentation, of at least 1 mm, and preferably between 1 and 5 mm, when the foot of the animal or a person is supported.

[0136] By "sinking", we mean in particular a reduction in thickness between the bearing portion 22 and the lower face 211 of the base 22, by bringing the respective surfaces closer together.

[0137] For this purpose, the floor covering 20 is advantageously made of at least one material capable of undergoing elastic deformation, chosen from:

[0138] - elastomeric materials, namely for example natural rubber, the "Synthetic natural" rubber (or synthetic polyisoprene), polybutadiene or styrene-butadiene, or

[0139] - plastic materials or thermoplastic elastomers (TPE), namely by Examples include PVB (Polyvinyl butyral), ABS (acrylonitrile butadiene styrene) / SBR (styrene butadiene), PP (polypropylene) / EPDM (ethylene propylene diene monomer), TPU (polyurethane TPE).

[0140] This floor covering 20 can be made:

[0141] - single-material, or

[0142] - multi-material, for example a first material forming the base and a second material forming the support portions.

[0143] According to a preferred embodiment, the base 21 incorporates a reinforcing layer 215.

[0144] The reinforcing layer 215 is advantageously chosen from textile fibers, metal or any other product providing stability and / or resistance to elongation.

[0145] This reinforcing layer 215 consists, for example, of a textile reinforcement, advantageously made of a material chosen from nylon, cotton, polyester, polyamide or any other reinforcing textile.

[0146] Such a floor covering 20 can be manufactured by assembling a set of superimposed parts to form a monobloc type assembly, for example:

[0147] - by vulcanizing an assembly of parts made of elastomeric material,

[0148] - by collage,

[0149] - by welding. Suction methods

[0150] The suction means 30 are adapted to ensure a suction power capable of exerting suction of liquids through the through orifices 245.

[0151] More generally, the suction means 30, which may include devices such as high-efficiency fans, are suitable for generating sufficient suction power.

[0152] This suction power is calibrated to create an adequate pressure difference to efficiently suction liquids.

[0153] When the suction means 30 are in operation, they generate a suction force which pulls the liquids through the through orifices 245, located in the bottom wall 24.

[0154] These through orifices 245, suitably distributed, allow an optimal flow of liquids, thus ensuring that unwanted liquids are evacuated quickly and efficiently.

[0155] The design of the suction means takes into account the specific characteristics of the liquids to be suctioned, such as viscosity and density, in order to maintain optimal performance of the collection system.

[0156] The suction means 30 advantageously include means for capturing ammonia and use an acidic solution for its conversion into fertilizer.

[0157] In the case of a slatted floor, the suction means 30 are advantageously connected to the pit for the purpose of gas suction. Implementation

[0158] In practice, the installation method for the collection system 10 according to the invention comprises the following steps:

[0159] - laying the floor covering 20 on the floor S and installing the suction means 30,

[0160] - drilling through holes 245 opposite the conduits SI of the floor S, by example using a cookie cutter.

[0161] In practice, laying the floor covering 20 amounts to covering the SI conduits with floor S.

[0162] Such a floor covering 20, before its installation, is advantageously stored in the form of plates, and preferably still in the form of rolls.

[0163] This latter form of embodiment in rolls has the advantage of allowing simple and quick installation of the floor covering 20 in the livestock enclosure by unrolling; it also ensures optimal continuity of the grooves for the efficient recovery of liquids at the ends of these grooves.

[0164] Following this installation, the through orifices 245 are provided (in particular in number and diameter) so as to obtain a total surface suitable in particular for the suction means 30.

[0165] In particular, the through-holes 245 are provided:

[0166] - opposite the slotted SI conduits, for the grating floor (figures 1 and 5), Or

[0167] - opposite the SI conduits in the form of longitudinal grooves, for the grooved floor ([Fig.7]).

[0168] In general, the floor covering 20 then allows liquids to flow into the grooves, thus preventing the accumulation of these liquids on the bearing portions which thus remain relatively dry.

[0169] Solid matter, in particular feces, remains mainly on the supporting portions, so as to avoid their mixing and to limit the production of ammonia within the rearing enclosure.

[0170] These solid materials are advantageously removed by scraping the support portions, using a scraping system advantageously chosen from among the usual systems.

[0171] And, in operation, these SI conduits are connected to the suction means 30, so as to generate the suction of liquids through the through orifices 245, via the SI conduits.

[0172] The suction means 30 advantageously create a suction flow at the level of the ducts SL. When these suction means are in operation, they generate a negative pressure that induces a continuous flow of air or liquid through the ducts SL. This suction flow extends to the through-holes 245, located in the bottom wall 24. The through-holes 245 are in fluidic communication (advantageously direct) with the ducts SL. This configuration allows for a smooth and uninterrupted transmission of the suction flow from the ducts SI to the holes 245. Consequently, unwanted liquids present on the surface of the floor covering 20 are efficiently attracted and removed through the holes by the generated suction power. This arrangement ensures rapid and efficient collection of liquids, thus maintaining the system in optimal operating condition.

[0173] Furthermore, the direction of the liquid flow through the through-holes 245 is determined by the pressure difference created by the suction means 30. The liquid flows from the upper face 241 of the bottom wall 24, where it initially accumulates, towards the lower face of the same bottom wall 24, in response to the negative pressure exerted. This movement of the liquid is directed, allowing for efficient drainage. This controlled direction of the liquid flow optimizes the collection process and prevents any stagnation, thus ensuring that the liquids are removed from the surface of the floor covering 20.

[0174] In general, the suction means 30 generate suction power.

[0175] And to maximize the efficiency of the system, the total surface area of ​​the through orifices 245 is adapted according to the suction power generated by the suction means 30.

[0176] The total surface area of ​​the through orifices 245 is advantageously defined by their diameters and their number.

[0177] The total surface area of ​​the through orifices 245, through which the liquids are aspirated, is advantageously calculated by combining the diameters and the number of orifices 245 through holes. In other words, each 245 through hole contributes to the total surface area, and optimizing their size and number is important to ensure optimal suction.

[0178] A correlation between the total surface area of ​​the orifices and the suction power is advantageous.

[0179] If the total surface area of ​​the orifices is too small, suction may be insufficient, resulting in inefficient liquid removal. Conversely, if the total surface area is too large, this could reduce suction pressure, also compromising the system's efficiency.

[0180] Thus, a balanced design is achieved by determining the total surface area of ​​the through orifices 245 as a function of the available suction power, ensuring that the system operates optimally.

[0181] This optimization of the total surface area of ​​the through orifices 245 / suction power is implemented by a person skilled in the art.

[0182] This approach allows for continuous and efficient aspiration of liquids through the through orifices 245, thus ensuring reliable and efficient operation of the collection system.

[0183] Of course, various other modifications can be made to the invention within the scope of the annexed claims.
