Definitions

  • the present invention relates to a trough and in particular to a trough from which farm animals can feed.
  • the trough is open-topped and is suited for containment of feed materials for feeding out simultaneously to a large number of animals, for example sheep or cattle.
  • the trough can be advantageously used in conjunction with one or more overhead electrified wires to reduce contamination and wastage of the feed material by deterring animals from walking or encroaching into or onto the trough.
  • Dry feed material can be distributed directly onto the ground or floor but significant wastage can occur from trampling and soiling by the animals. It is known to contain the dry feed in troughs or other containment devices to reduce spoilage from the animals. These devices often provide only a short perimeter length at which only a limited number of animals can access the feed. Where large numbers of animals are grouped together, shy feeders can be disadvantaged by not getting access to the feed material until the more dominant animals are sated, leaving less desirable or even insufficient feed remaining.
  • An object of at least one embodiment of the invention is to provide a trough for containing feed material, or at least to provide the public with a useful choice.
  • the invention may be broadly said to be a trough comprising an elongate trough body and at least one elongate support element, wherein:
  • the invention may be broadly said to be a trough comprising an elongate trough body and at least one elongate support element, wherein:
  • the restraint extends transversely from one side of the trough to the other.
  • the restraint may be a wire.
  • the at least one side wall portion has at least one perforation, and an outer end of the restraint extends outwardly through the perforation to connect to the support element.
  • An outer end of the restraint may be formed with a loop through which the at least one elongate support element passes to connect the support element to the restraint.
  • the restraint may be a substantially rigid U-shaped bracket that extends transversely across the trough.
  • the at least one elongate support element may be substantially rigid.
  • the side wall portion is maintained upright at least in part by tension in the elongate support element.
  • the at least one support elongate element may be tensioned between two anchor devices which are located at respective ends of the support element.
  • the at least one support element may be supported at a predetermined height at one or more locations intermediate its ends.
  • the at least one support element may be a wire.
  • the trough body has two opposed side wall portions which extend along respective opposite longitudinal sides of the trough
  • the side wall portion may be integral with the bottom portion.
  • the trough body is formed from a sheet.
  • the sheet is continuous along the length of the trough.
  • the trough may comprises discrete length portions that are distributed along the length of the trough, and are formed from respective sheets. The discrete length portions may be distributed along the length of the trough with adjacent discrete portions partially overlapping one another.
  • the sheet or each respective sheet may be made of a resilient semi-rigid material.
  • the sheet or each respective sheet may be made of a plastics material.
  • the sheet or each respective sheet may be provided with a line of weakness about which the sheet or each respective sheet preferentially bends when the side wall portion is made non-planar with the bottom portion.
  • the sheet or each respective sheet may be creased to provide the line of weakness.
  • the sheet or each respective sheet may be provided with perforations along the line of weakness.
  • the bottom portion is perforated to provide one or more drainage holes.
  • FIG. 1 shows a perspective view of part of a first trough according to the current invention
  • FIG. 2 shows a partly diagrammatic transverse cross-sectional view of a second trough according to the invention
  • FIG. 3 shows a partly diagrammatic transverse cross-sectional view of a third trough according to the invention
  • FIG. 4 shows a perspective view of part of a fourth trough according to the current invention.
  • FIG. 5 shows a perspective view of representative end portions of a fifth trough according to the current invention.
  • FIG. 1 shows a perspective view of part of a first embodiment of a trough 10 .
  • the trough is placed on the ground, for example out in a paddock, or alternatively on a floor surface, for example in a barn.
  • the trough is elongate and comprises an elongate trough body 12 and two elongate support elements in the form of longitudinal supports 14 , 15 .
  • the trough body is made from a sheet material that provides a floor or bottom portion 16 of the trough body, and two opposed side wall portions which extend upwardly from opposite elongate side edges of the floor portion to form the trough side walls 18 , 19 .
  • the sheet material is laid out on a floor or ground surface and folded, bent or curved along two spaced and generally parallel lines to form both trough side walls integrally with the trough floor.
  • the longitudinal supports 14 , 15 extend along respective outer faces 20 of the opposite side walls below the upper edges 22 , 23 of the side walls 18 , 19 but higher than the floor or bottom portion 16 of the trough.
  • the side walls are maintained upright at least in part by the respective supports 14 , 15 .
  • the longitudinal supports 14 , 15 may each be made from a rigid or semi-rigid material, for example a tube or pipe or a high tensile steel wire or rod.
  • the side walls may be maintained upright at least in part by tension in the respective supports 14 , 15 .
  • the supports 14 , 15 may be wires that are tensioned between two anchor devices (not shown in the figures) located at respective opposite ends of the wires.
  • the longitudinal supports 14 , 15 can be supported at a predetermined height by one or more blocks or posts at intermediate locations between the ends of the support wires. This is particularly useful to hold support wires at a desired height above an uneven ground surface, for example where the trough extends over a relatively high point and the tension in the support wires could tend to pull the support wires down and collapse the side walls, or conversely where the trough extends over a relatively low point and the tension in the support wires could tend to lift the support wires and the side walls, and at least partially close the trough.
  • the blocks or posts may be a peg 25 driven into the ground as shown in FIG. 1 .
  • the support may be secured to the top or a side face of the peg, for example by a U-shaped staple or other suitable fastener.
  • Perforations 30 are provided in the trough side walls 18 , 19 . As shown in FIG. 1 , the perforations are approximately at a mid-height position in the side walls. The perforations may be provided at other heights. The perforations are provided as pairs of transversely-aligned perforations with the two perforations of each pair respectively provided in the two opposed side walls. The pairs of perforations are distributed at intervals, e.g. at 2 metre intervals, along the length of the trough body.
  • Restraints 26 extend transversely across the width of the trough. As best seen in the two magnified part views of FIG. 1 , loops 27 at the ends of the restraints protrude partially through respective perforations 30 in the side walls.
  • the supports 14 , 15 lying along the outer faces of the side walls pass through the loops to restrain the supports, and thus the side walls, from outward movement, i.e. movement away from the longitudinal centreline of the trough.
  • the side walls 18 , 19 are restrained and held upright, at least in part, by the restraints 26 and by the two supports 18 , 19 .
  • a restraint 26 or a support 18 , 19 is a wire
  • the side walls 18 , 19 may be restrained and held upright, at least in part, by tension in the restraint wire or the support wire.
  • Each restraint 26 may be fashioned from a length of wire, as seen in FIG. 1 .
  • the restraints may be flexible so that if pressure is applied to the outer face of a side wall 18 , 19 , for example by an animal feeding at the trough, the side wall can bend inward at least in the in the locality of the applied pressure.
  • two or more elongate support wires can be used along one or each side wall of the trough.
  • a high trough side wall can be supported by a pair of support wires, one above the other, with the support wires connected to the ends of respective upper and lower sets of transverse restraint wires through respective upper and lower sets of perforations in the side walls.
  • each restraint wire 26 may be threaded through a respective tube that is located between the side walls to help reduce inward movement of the side walls and maintain the distance between the two side walls.
  • the tube may be a length of alkathene pipe.
  • the tubes may have a diameter that is greater than that of the perforations 30 in the side walls so that the end of the tube cannot pass through the perforation and instead engages against the inner face of a respective side wall.
  • a washer or similar device having an outer dimension that is greater than the diameter of the perforations 30 in the side walls, and perforated with a hole with a diameter that is smaller than the tube diameter, is placed between a respective end of the tube and the inner face of the side wall.
  • the sheet material is preferably a resilient, semi-rigid plastics material such as a heavy duty polyethylene, polythene or polypropylene.
  • the trough side walls may be biased to push outwards against the support wires by the inherent resilience, or ‘memory’, of the sheet material.
  • the rigidity of the sheet material is sufficient so that the upper edge portion of the upright side walls, which is cantilevered above the support wires 14 , 15 , is maintained substantially upright.
  • the trough body is a polyethylene plastics sheet material with a thickness of either 2 mm or 3 mm.
  • the invention is not limited to troughs having bodies made from the above-mentioned sheet plastics materials and sheet thicknesses.
  • inward movement of the side walls 18 , 19 may be restrained by making the transverse restraints sufficiently rigid and securing the outer ends of the restraints to the side walls.
  • enlargements, for example loops 27 , at the outer ends of the transverse restraints 26 , 76 may be secured, for example by tying with a cable tie passing through a corresponding perforation 30 in one of the trough side walls 18 , 19 , to an object, for example a washer or short length of pipe or tube that is located at the outside of the trough wall.
  • Each enlargement at an end of a restraint, and the washer, pipe or tube to which it is tied, has a dimension larger than the diameter of the corresponding perforation 30 in the side wall 18 , 19 so that the enlargement and the washer, pipe or tube cannot pass through the perforation.
  • the side wall is secured to the end of the restraint.
  • the side walls may be held outward, at least in part, by rigidity in the restraints.
  • a wave, or upright ribs or corrugations may be formed in the side walls to enhance the rigidity of the side walls.
  • the wave or ribs or corrugations may be pre-formed in the longitudinal edge portions of the sheet material by thermoforming, or by stretching the material beyond its elastic limit.
  • the wave or corrugations stiffen the side walls and help support the side walls, and particularly the cantilevered upper edge portion of the side walls above the support wires 14 , 15 , in an upright position.
  • the sheet material may be provided with lines of weakness (not shown in the figures) about which the sheet material preferentially bends when the side walls are erected.
  • the lines of weakness may be formed by creasing the sheet, or by forming indentations or perforations in the sheet, along the intended lines of weakness.
  • the trough may be perforated with drainage holes (not shown in the figures) to allow rain water or other liquids to readily drain from the trough.
  • the sheet material may be continuous along the length of the trough body.
  • the trough body may be divided into discrete body portions that are distributed along the length of the trough body.
  • the discrete body portions are distributed along the length of the trough body with adjacent body portions partially overlapping one another, as can be seen in the overlap 29 shown in FIG. 1 .
  • Respective pairs of side wall perforations in each of two overlapping body portions may be aligned and the loops at the ends of one restraint wire 26 A passed through the perforations to restrain the support wires and maintain the overlap 29 between the two adjacent body portions.
  • the trough according to the invention described in this specification can be extended to any desired length, if necessary by joining overlapping body portions as described above, over a flat or undulating surface, to provide access for any desired number of animals to feed simultaneously. This allows all animals in a group to access sufficient feed without disadvantaging shy feeders that might be reluctant to compete against more dominant animals in restricted feeding arrangements.
  • the ends of the trough can be closed but generally end closures are not necessary if only dry (i.e. not liquid) feed material is used in the trough and the feed material is not placed near the ends of the trough.
  • FIGS. 2 and 3 show partly diagrammatic transverse cross-sectional views of second and third embodiments of the invention. Features corresponding to those discussed above and labelled in FIG. 1 are labelled with like numerals in FIGS. 2 and 3 .
  • FIG. 2 shows a generally U-shaped cross-section of the trough body formed from the sheet material.
  • the transitions between the trough bottom and the two side walls may be curved as shown, or may be folded or creased to give a smaller radius of curvature.
  • a trough according to the invention is used in conjunction with generally horizontal electrified wires 40 , 41 which extend parallel to and above the trough.
  • the wires are suspended from the outer ends of a plurality of spaced apart outriggers.
  • Each outrigger comprises a pair of arms 42 , 44 which are freely suspended from an insulating hanger 45 that is pivotably attached to a respective support post 46 .
  • Each support post is driven into the ground through a suitably sized aperture in the bottom 16 of the trough 10 .
  • each outrigger is freely suspended from an insulating hanger 45 that is pivotably attached to a generally horizontal wire which is tensioned between a pair of posts, similarly to the arrangement shown in FIG. 5 .
  • the electrified wires are each tensioned between two anchor devices (not shown in the figures), e.g. posts, which are located at respective opposite ends of the electrified wires.
  • the outriggers are distributed along the length of the trough to support the electrified wires at a predetermined height above the trough.
  • the height of the electrified wires is selected to allow animals to feed from the trough but deter the animals from walking or trampling on the trough or the feed material in the trough.
  • the electrified wires if contacted by an animal, can readily move away from a rest position without being substantially deformed or damaged, and can then return back to the rest position after the animal has recoiled from the electric shock.
  • This arrangement reduces wastage and spoilage of the feed material which is generally contained within the trough in an unspoiled and uncontaminated condition until consumed by the feeding animals.
  • the support wires instead of being restrained against outward movement by the restraint wires 26 described above, are restrained and supported by one or more U-shaped brackets.
  • Each bracket has a pair of limbs which extend upward from opposite ends of a middle body portion.
  • the brackets are substantially rigid, or semi-rigid and resilient and may be made from spring steel.
  • a U-shaped bracket is located outside the trough body.

  • a return portion 54 , 55 at the upper end of the limb extends over the top edge 22 , 23 of the wall and down the outside of the wall.
  • a support wire 14 , 15 is secured to the lower end of the return portion 54 , 55 , located part way down the outside of the side wall 18 , 19 , to restrain the support wire from inward and outward movement and to support the support wire at a desired height.
  • a tie for example a cord or wire 56 , may be passed under the bottom of the trough body to help hold the trough body in the U-shaped cross-section and the trough side walls in place.
  • FIG. 4 shows another trough embodiment, with a U-shaped bracket 60 located largely, but not completely, inside the trough body.
  • the trough has a generally rounded U-shaped cross-section and is formed from the sheet material.

  • an elongate trough body 12 is supported by two longitudinal support wires 14 , 15 .
  • Each of the support wires is tensioned between two strainer posts 71 , 72 which are located at respective opposite ends of the wires.
  • a substantially horizontal transverse spreader 73 , 74 may be located between each strainer post and a respective end of the trough body 12 to hold the two support wires apart by a distance that is approximately the same as a desired width of the trough.
  • FIG. 5 is similar to that shown in FIGS. 1 and 2 , in that: the support wires 14 , 15 extend along respective outer faces of the opposite side walls 18 , 19 below the upper edges of the side walls but higher than the floor or bottom portion 16 of the trough; the trough side walls are maintained upright at least in part by tension in the respective support wires 14 , 15 ; pairs of transversely-aligned perforations are provided in the opposed trough side walls, for example at a mid-height position in the side walls; and the pairs of perforations are distributed at intervals along the length of the trough body.

  • Each restraint 26 , 76 may be fashioned from a length of wire.
  • the restraints 26 , 76 may be flexible so that if pressure is applied to the outer face of a side wall 18 , 19 , for example by an animal feeding at the trough, the side wall can bend inward.
  • the upright orientation of the side walls may be facilitated by sloping the restraint wire 76 upward from its outer end toward its attachment to the respective post 77 .
