Description

Title of the invention: Separator for a livestock building, in particular for cattle Technical field of the invention

[0001] The present invention relates to the technical field of breeding.

[0002] It relates in particular to separators for a livestock building, in particular for cattle. State of the art

[0003] In a livestock building, particularly for cattle, it is useful to install separators to delimit the space available for each animal and to reduce the pressure of dominant animals at the trough.

[0004] Such separators are generally installed on comadis barriers. They can also be useful along rest areas, particularly cubicles.

[0005] However, in practice, the structure of these separators is not always optimal, with risks of injury to the animals or too little restraint for good positioning and therefore good hygiene.

[0006] To limit this risk, there are separators which include:

[0007] - a rigid front part, comprising at least one metallic tubular member, and

[0008] - a flexible rear part,

[0009] However, current flexible separators are not yet entirely satisfactory from an installation point of view.

[0010] Indeed, the receiving structures often comprise a metal frame intended to receive securing interfaces carried by the separators.

[0011] However, the positioning of these securing interfaces is sometimes not suitable for certain reception structures. Presentation of the invention

[0012] In order to overcome the aforementioned drawback of the state of the art, the present invention proposes a separator for a livestock building, in particular for cattle, intended to be secured to a receiving structure, for example a comadis barrier.

[0038] — a free rear section, forming said rear part,

[0039] preferably, the internal section of said at least one conduit for receiving said metallic tubular member corresponds, apart from the clearance, to the external section of said front section of said at least one flexible longitudinal member, and

[0040] preferably, the rear section of the flexible longitudinal member extends cantilevered from the metal tubular member,

[0048] which separation system comprises:

[0049] - several separators according to the invention,

[0050] and possibly

[0051] - an attached longitudinal bar, intended to be secured to said separators juxtaposed, and / or

[0052] - spraying means, for cooling animals, advantageously generously carried by said added longitudinal bar.

[0053] The invention also relates to a livestock building equipped with a separation system according to the invention, attached to a receiving structure, for example a comadis barrier.

[0054] Of course, the various features, variants and embodiments of the invention may be combined with each other in various combinations to the extent that they are not incompatible or mutually exclusive. Detailed description of the invention

[0055] Furthermore, various other characteristics of the invention emerge from the appended description given with reference to the drawings which illustrate non-limiting forms of embodiment of the invention and where:

[0056] [Fig-1] is a schematic side view of a separator according to the invention;

[0057] [Fig.2] is a partial and enlarged view of the separator according to [Fig.l], illustrating in in particular the assembly between the two metal tubular organs;

[0058] [Fig.3] is a partial and enlarged view of the separator according to [Fig.l], illustrating in in particular the lower joining interface.

[0059] It should be noted that, in these figures, the structural and / or functional elements common to the different variants may have the same references.

[0060] The present invention thus relates to a separator 1 for a livestock building B, in particular for cattle.

[0061] The separator 1 is intended to be secured to a receiving structure C (shown very schematically in the figures), for example a comadis barrier or within cubicles (not shown).

[0062] Such a separator 1 is particularly useful for delimiting the space available for each animal (for example cattle, and in particular dairy cows).

[0063] At a comadis barrier C, the separator 1, also called a “comadis separator”, is particularly useful for delimiting the space available for each animal (for example cattle, and in particular dairy cows) within a feeding path M.

[0064] In this case, the separator 1 is intended to be secured to the headlock barrier C, advantageously conventional in itself.

[0065] Generally speaking, such a headlock barrier C comprises two longitudinal bars C1, C2 (one lower C2 and the other upper C1), horizontal, connected by vertical uprights C3, C4.

[0066] Pairs of uprights C3, C4 delimit, with the two longitudinal bars C1, C2, an opening suitable for the passage of an animal's head.

[0067] To ensure restraint, a first upright C3 of each pair of uprights C3, C4 is equipped with an oscillating restraint bar C5.

[0068] The oscillating restraining bar C5, opposite the second upright C4, is advantageously movable between two end-of-travel positions:

[0069] - a “free” position, advantageously inclined, to allow the passage of the head of the animal in both directions, and

[0070] - a “containment” position, advantageously vertical and parallel to the second C4 upright, preventing the animal's head from passing in either direction.

[0071] Generally speaking, the separator 1 comprises two parts:

[0072] - a front part 5, rigid, advantageously intended to extend at the level of the head and the shoulders of the animal, and

[0073] - a flexible rear part 6, advantageously intended to extend at the level of the flanks of the animal.

[0074] The front part 5 and the rear part 6 advantageously extend in the same general plane P, preferably vertical and perpendicular to a longitudinal plane C' of the receiving structure C.

[0075] The front part 5 and the rear part 6 advantageously have particular dimensions (measured in the general plane P), namely preferably:

[0076] - the front part 5 has a horizontal dimension ranging from 20 to 50 cm (perpendicular to the longitudinal plane C' of the receiving structure C, advantageously corresponding to the center distance between a rising section 521 of the front part 5 and the means 7 for securing with the receiving structure C, described below), and

[0077] - the rear part 6 has a horizontal dimension ranging from 50 to 150 cm (perpendicular to the longitudinal plane C' of the receiving structure C, advantageously corresponding to the center distance between the rising section 521 of the front part 5 and a rear end 6a of the rear part 6, free, described below).

[0078] Generally, the front part 5 advantageously extends cantilevered from the receiving structure C; and the rear part 6 advantageously extends cantilevered from the front part 5. Front part

[0079] The front part 5, rigid, comprising at least one metallic tubular member 51.

[0080] Said at least one metallic tubular member 51 advantageously has the dimensions following, which can be taken in combination or independently of each other:

[0081] - a diameter ranging from 40 to 70 mm, and

[0082] - a thickness ranging from 2 to 5 mm.

[0083] Said at least one metallic tubular member 51 comprises means 7 for securing it to the receiving structure C, namely at least two securing interfaces 71, 72.

[0084] Said at least two securing interfaces 71, 72 are each intended to ensure securing between said at least one metallic tubular member 51 and said receiving structure C.

[0085] Said at least two securing interfaces 71, 72 are advantageously superimposed in the general plane P.

[0086] And, according to the invention, this front part 5 is structured to allow translational play between the securing interfaces 71, 72, so as to allow adjustment in spacing between these securing interfaces 71, 72.

[0087] In other words, the adjustment in spacing between the securing interfaces 71, 72 advantageously corresponds to an adjustment in distance between these securing interfaces 71, 72 according to a dimension J defined in the general plane P, said dimension being intended to extend parallel to the longitudinal plane C' of the receiving structure C.

[0088] The dimension J still advantageously corresponds to a distance defined by the center distances 71', 72' passing through the two securing interfaces 71, 72

[0089] According to a preferred embodiment, the front part 5 comprises at least two metal tubular members 52, 53 which each comprise at least one of the securing interfaces 71, 72.

[0090] And said at least two metal tubular members 52, 53 cooperate by means of at least one sliding assembly 8, allowing translational play between said metal tubular members 52, 53.

[0091] More preferably, said at least one sliding assembly 8 is chosen from:

[0092] - a pair of assembly sections 81, in which the tubular members me metals 52, 53 cooperate by fitting, advantageously in combination with translation locking means (not shown - for example a translation locking screw), or

[0093] - a connecting interface 82, adjustable over the length of at least one of said metal tubular members 52, 53, advantageously in combination with translational locking means (not shown - for example a translational locking screw).

[0094] In particular, on the one hand, the pair of assembly sections 81 advantageously forms a telescopic structure.

[0095] As developed subsequently, the metal tubular members 52, 53 comprise sections fitted into one another, while allowing relative translational movement.

[0096] On the other hand, the connecting interface 82 advantageously comprises a clamping collar which is, on the one hand, adjustable in sliding along the length of a metal tubular member 52 and, on the other hand, carried by one end of the other metal tubular member 53.

[0097] According to a preferred embodiment, said front part 5 comprises two metal tubular members 52, 53, assembled with a translational clearance, namely:

[0098] - a first metallic tubular member 52, generally C-shaped, opening towards the receiving structure C, and

[0099] - a second metallic tubular member 53, forming a crosspiece, extending between the receiving structure C and the first metal tubular member 52.

[0100] The first metallic tubular member 52 comprises at least three structural sections, namely:

[0101] - an upward section 521, advantageously comprising at least one portion rectilinear over all or part of its length, intended to come opposite and at a distance from the receiving structure C,

[0102] - a lower return section 522, a front end 522a of which carries an interface lower solidarity 71, and

[0103] - an upper return section 523, advantageously comprising a transverse arm 5231 and a rising arm 5232.

[0104] The rising arm 5232 has a front end 5232a.

[0105] Preferably, the rising section 521 and the rising arm 5232 extend parallel to each other.

[0106] The second metallic tubular member 53, forming a crosspiece, advantageously rectilinear, has two ends:

[0107] - a front end 531, equipped with an upper securing interface 72,

[0108] - a rear end 532, comprising a connecting interface 82, interposed between the second metal tubular member 53 and the rising section 521 of the first metal tubular member 52, said connecting interface 82 being adjustable over the length of this rising section 521.

[0109] The connection interface 82 advantageously comprises a combination of two collars 821, 822 ([Fig.2]):

[0110] - a first collar 821, also called “sleeve”, fitted onto the rear end 532 of the second metallic tubular member 53, and

[0111] - a second collar 822, surrounding the rising section 521 of the first member metallic tubular 52, advantageously on a rectilinear portion.

[0112] This second metal tubular member 53 also comprises a lateral assembly section 533, cooperating by fitting with the upper return section 523 of the first metal tubular member 52 (in particular in its rising arm 5232), forming a pair of assembly sections 81.

[0113] In other words, the assembly section 533 is introduced here through the front end 5232a of the rising arm 5232.

[0114] Preferably, the assembly section 533 and the rising arm 5232 are rectilinear and coaxial, to promote sliding.

[0115] For example, the length of the assembly section 533 and the rising arm 5232 is 10 to 35 cm.

[0116] Again generally, the inner section of the rising arm 5232 corresponds, apart from the clearance, to the outer section of the assembly section.

[0117] Advantageously, the lateral assembly section 533 is provided between the front end 531 and the rear end 532 of the second metal tubular member 53.

[0118] Preferably, the assembly section 533 extends parallel to the rising section 521 of the first metal tubular member 52.

[0119] Preferably, the assembly section 533, forming a male part, is introduced and slides in the rising arm 5232 of the upper return section 523 (forming a female part).

[0120] Thus, the second metal tubular member 53 is here movable in sliding, parallel to itself, over at least a rectilinear portion of the length of the rising section 521 and in a direction parallel to this rising section 521.

[0121] Furthermore, in general, the securing means 7 are advantageously chosen from mechanical connection means suitable for securing with the receiving structure C, for example collars coming around the longitudinal bars and / or the vertical uprights.

[0122] Such securing means 7 are for example described in document FR3124924.

[0123] For example, for a reception structure C in the form of a comadis barrier, the securing means 7 comprise:

[0124] - an upper securing interface 72 ([Fig.2]), adapted to be secured with an amount C3, C4 of the comadis barrier C, and

[0125] - a lower securing interface 71 ([Fig.3]), adapted to be secured with a longitudinal bar Cl, C2 of said comadis barrier C.

[0126] Preferably, the upper securing interface 72 consists of a fixing collar.

[0127] More precisely, this upper securing interface 72 advantageously comprises- nicely a combination of two collars 721, 722 ([Fig.2]):

[0128] - a first collar 721, also called “sleeve”, fitted onto the front end 531 of the second metallic tubular member 53, and

[0129] - a second collar 722, surrounding the upright C3, C4 of the headlock barrier C, advantageously on a straight portion.

[0130] Preferably, the lower securing interface 71 comprises two securing zones 711, adapted to be secured to the longitudinal bar C1, C2 of the headlock barrier C, on either side of an upright C3, C4 ([Fig.3]).

[0131] More preferably, the lower securing interface 71 comprises two flanges 711 adapted to be positioned around the longitudinal bar C1, C2 of the headlock barrier C, on either side of the upright C3, C4.

[0132] Generally speaking, still according to a preferred embodiment illustrated in [Fig.l], said at least one metallic tubular member 51 comprises at least one female receiving conduit 522, which comprises a rear end 5222 provided with an opening 5223 opening opposite the securing interfaces 71, 72.

[0133] As developed subsequently, said at least one receiving conduit 522 is intended to receive a section of the rear part 6 by fitting.

[0134] In this case, said at least one receiving conduit 522 extends over at least part of the length of at least one of the structural sections 521, 522, 523 of the first metal tubular member 52, preferably at least one of the two return sections 522, 523.

[0135] More preferably, said at least one receiving conduit 522 is formed by the lower return section 522 (designated by the same reference for the sake of understanding).

[0136] The opening 5223 of said at least one receiving duct 522 is advantageously provided at the junction between the receiving duct 522 (in other words the lower return section 522) and said rising section 521.

[0137] Said at least one receiving conduit 522 of said metallic tubular member 51 defines an angle ranging from 1° to 50° relative to a horizontal plane, with an increasing slope in the front to rear direction. Rear part

[0138] According to one embodiment, the flexible rear part 6 comprises (or even consists of) at least one flexible longitudinal member 6 (designated by the same reference for the sake of simplicity).

[0139] By “longitudinal member” is advantageously meant a part having the general shape of a bar.

[0140] By “flexible longitudinal member 6” is meant in particular a longitudinal member which is capable, on the one hand, of being deformed by the animal coming to bear on the part rear 6 and, on the other hand, to completely resume its shape after the animal stops supporting it.

[0141] Each flexible longitudinal member 6 is advantageously rectilinear, at rest.

[0142] A flexible longitudinal member 6 is for example made of a plastic material, chosen for example from HDPE, PP, advantageously tubular.

[0143] A free rear end 6a of this flexible longitudinal member 6 advantageously comprises a protective element, advantageously a spherical part (also advantageously a part in the form of a spherical cap).

[0144] The flexible longitudinal member 6 advantageously has the following dimensions, which can be taken in combination or independently of each other:

[0145] - a length ranging from 200 to 2,000 mm,

[0146] - a diameter ranging from 20 to 70 mm,

[0147] - a thickness ranging from 5 to 20 mm.

[0148] Generally, said at least one flexible longitudinal member 6 comprises:

[0149] - a front section 61 (not visible), male, which is introduced into said at least one receiving conduit 522, through said opening 5223, advantageously in a removable manner, and

[0150] - a free rear section 62, forming said rear part 6.

[0151] Preferably, the front section 61, male, is introduced into said at least one receiving conduit 522, through said opening 5223, without translational locking means.

[0152] The rear section 62 extends cantilevered from the metal tubular member 51.

[0153] Preferably, said at least one front section 61 of said at least one flexible longitudinal member 6, and said at least one receiving conduit 522 of said metallic tubular member 51, are rectilinear.

[0154] Still generally, the internal section of said at least one receiving conduit 522 of said metallic tubular member 51 corresponds, apart from the clearance, to the external section of said at least one front section 61 of said at least one flexible longitudinal member 6.

[0155] And, preferably, the rear section 62 of the flexible longitudinal member 6 extends cantilevered from said at least one metal tubular member 51.

[0156] More preferably, said at least one flexible longitudinal member 6 defines an angle ranging from 1° to 50° relative to a horizontal plane, with an increasing slope in the front to rear direction. Separation system

[0157] In practice, the invention is implemented in the form of a separation system which comprises:

[0158] - several separators 1 according to the invention, advantageously in battle,

[0159] and possibly

[0160] - an attached longitudinal bar 10, intended to be secured to the separators 1 juxtaposed, and / or

[0161] - spraying means 11, for cooling the animals, advantageously generously carried by the added longitudinal bar 10.

[0162] The structure of the separators 1 has the advantage of offering a solution adaptable to a range of reception structures C.

[0163] In particular, the securing interfaces 71, 72 are here adjustable in spacing, which makes it possible to remedy the problems of space requirements at the level of the receiving structure C.

[0164] In this case, the separator 1 can be positioned at the level of the receiving structure C.

[0165] If necessary, the second metal tubular member 53 can be maneuvered by sliding along the rising section 521 of the first metal tubular member 52, so as to adjust the spacing of the securing interfaces 71, 72 according to the conformation of the receiving structure C.

[0166] During this movement, the assembly section pair 81 also adjusts in length: the assembly section 533 of the second metal tubular member 53 slides within the rising arm 5232 of the upper return section 523.

[0167] For example, the second metal tubular member 53 is movable so that the dimension J is advantageously 10 to 25 cm.

[0168] In other words, the second metal tubular member 53 is movable in translation over a stroke of 5 to 25 cm.

[0169] More generally, the second metal tubular member 53 is advantageously movable, relative to the rising arm 5232 of the upper return section 523, over a stroke ranging from:

[0170] - a maximum high position, at a distance from the lower return section 522, in in which the second metal tubular member 53 rests on the rising arm 5232 of the upper return section 523 (in particular at its front end 5232a), and

[0171] - a low maximum position, close to the lower return section 522, in which the second metal tubular member 53 is spaced from the rising arm 5232 of the upper return section 523 (in particular from its front end 5232a).

[0172] When the securing means 7 are suitably positioned, the latter are secured to the receiving structure C.

[0173] In parallel, said at least one sliding assembly 8 is locked, advantageously via the translation locking means (not shown - for example a translation locking screw), to contribute to the stability of the separator 1.

[0174] Furthermore, the added longitudinal bar 10 is secured here to the front part 5, preferably at the level of the upper end of the rising section 521 or at the level of the upper return section 523.

[0175] Still generally, the spraying means 11 consist for example of nozzles connected to a water supply circuit.

[0176] The livestock building B is thus equipped with a separation system according to the invention, attached to a reception structure C, for example a comadis barrier.

[0177] If necessary, to circulate with a machine between two rows of separators 1, it is possible to temporarily dismantle the rear part 6 of the latter.

[0178] The machine can then circulate in the “widened” space which is delimited by the front parts 5 of these two rows of separators 1.

[0179] At the end of the intervention, the rear parts 6 of these two rows of separators 1 can be put back in place.

[0180] Of course, various other modifications may be made to the invention within the scope of the appended claims.
