    Improvements in or relation to feed boxes
    Field of the Invention
    The present invention concerns improvements in or relation to a feed box of the kind indicated in the preamble of claim 1.
    Background of the Invention
    Many prior art feed boxes of this kind are designed with a predominantly cylindrical container part that often includes a transparent container part - if the container is not made entirely of transparent material - such that the actual amount of feed content in the actual feed box/feed position always can readily be ascertained,
    The container part is usually connected upwardly with an endless tube conveyor supplying feed to the feed box from a feed station. The container part is downwards designed with a funnel-shaped part with a discharge valve which e.g. includes a spherical valve body.
    The spherical valve body is frequently operatively connected with a common control wire running along the tube conveyor such that the common control wire can operate one or more rows of feed boxes/feed positions. A common problem with existing feed boxes it the difficult in minimizing the portions of feedstuff discharged to specific feed positions or specific animals.
    Object of the Invention
    It is the object of the invention to indicate an improved feed box of this type, and which by means of very simple technical means can achieve a significantly improved operation of feed boxes of this type.
    Description of the Invention
    The feed box according to the invention is peculiar in that said valve body is provided with a number of radial wing parts which divides a lower interior bottom part of the feed box in the vi cinity of said discharge opening.
    By simple mechanical means is hereby achieved an improved feed box of the type indicated in the introduction, with very significant improvements in use. In other words it is hereby obtained a significant improved possibility to minimizing the portions of feedstuff discharge through said discharge opening.
    By very simple technical or mechanical means is hereby obtained that feedstuff let in from the supply channel by means of said radial wing parts is prevented also to fill up the opposite part of said lower funnel-shaped bottom part. In other words an improved possibility of minimizing the amount of feedstuff being inlet through said vertical supply channel is hereby obtained.
    Appropriately, the feed box according to the invention may be such provided that outer edges of said wings parts have shapes complementary to that of exterior wall parts of said lower interior bottom part of the feed box.
    Preferably, the feed box according to the invention may be such provided that said valve body is provided with two radial wing parts which are positioned along a transverse centre line of the valve body, the latter being pear-shaped.
    Alternatively, the feed box according to the invention may be such provided that said valve body is provided with three radial wing parts, two of which are positioned along a transverse cen tre line of the valve body, while the third wing part is positioned midways to said two radial wing parts at the rear side of the valve body - as seen from a supply channel for feedstuff.
    Description of the Drawing
    The invention is explained more closely in the following with reference to the drawing, on which:
    Fig. 1 shows a perspective view of an embodiment of a feed box according to the invention,
    Fig. 2 shows a sectional view of the feed box shown in Fig. 1 and partly filled with feedstuff delivered via an endless tube conveyor,
    Fig. 3 shows a perspective view of the feed box cf. Fig. .1 with a partial cut-out in bottom front part for illustrating a new and improved pear-shaped valve body having radial wing parts,
    Fig. 4A show's a plane side view' of a preferred pear-shaped valve body having radial wing parts - as seen from the edge of the radial wing parts,
    Fig.4B shows another plane side view of the preferred pear-shaped valve body ef. Fig. 4A - as seen towards the radial wing parts,
    Fig. 4C shows a perspective view of the preferred pear-shaped valve body shown in Figs. 4A and 4B, and
    Fig. 4D show's a plane view of the pear-shaped val ve body with radial wings - as seen from above.
    Detailed Description of the Invention
    The feed box 2 shown in Figs. 1-3 is adapted for being upwardly connected to an endless tube conveyor 4 by means of brackets 6 such that the feed box 2 is suspended under the tube conveyor 4 and is supplied with feed, from the tube conveyor 4 via an upper supply opening 8 and vertical supply and channel 9.
    At the bottom, the feed box 2 is comiected with a feed position by a not shown down pipe connected with a low'd* discharge opening 10 w'hich is formed in a iow'er funnel-shaped part 12 of the feed box 2 such that a valve seat 14 for a downwardly spherical valve body 16 is formed at the transition between the funnel-shaped part 12 and the discharge opening 10.
    The valve body 16 is upwardly provided with an eyelet 18 through which a flexible release wire or cord 20 is extending, of which one end is running upwards and con nected with a common control wire running through the stable along the tube conveyor 4 and operating one or more rows of feed boxes 2.
    The opposite free end of the release wire or cord 20 is connected with an actuation handle 24 outside at one side of the feed box 2 and arranged to assume two positions, namely a lower position 26 corresponding to the valve body 16 being actively connected with the common control wire, and an upper positon 28 corresponding to the valve body 16 not being in active connection with the common control wire, i.e. an actuation pull in the common control wire will not act on the thus uncoupled valve body 16. The feed box 2 in question is thus disconnected from the common control wire as the connection between the former and the valve body 16 is extended in that the actuation handle 24 is disposed in the upper position 28.
    The actuation handle 24 thus has an alternative function as the handle 24 can be released from the lower position 26 and moved manually downwards in order to lift the valve body 16, whereby an amount of feed can be dosed to a certain feed position, e.g. with the object of calming the animal or animals in the actual feed position.
    As indicated in Figs. 2 and 3 the pear-shaped valve body 16 is provided with with a number of radial wing parts 30 which divides said lower funnel-shaped bottom part 12 of the feed box 2 in the vicinity of said discharge opening 10.
    By very simple technical or mechanical means is hereby obtained that feedstuff let in from the supply channel 9 by means of said radial wing parts 30 is prevented also to fill up the opposite part of said lower funnel-shaped bottom part 12. In other words an improved possibility of minimizing the amount of feedstuff being inlet through said vertical supply channel 9 is hereby obtained.
    In practice the normal amount of about 1.6 litres hereby may be reduced by about 0.2 litres to an amount of about 1.4 litres corresponding to a reduction or saving of about 12.5 % of each portion of feedstuff delivered to each feeding positions. In the end such a saving of about 12.5 % may be considered very' important - as seen from an economic point of view.
    On the other hand the reduction of some 0.2 litres would also be considered important as seen from a point of view regarding the animal welfare of a sow in the period of time just before farrowing - where it may be important not to give the sow to large portions of feedstuff.
    Figs. 4A-4D show' how - by way of example - a pear-shaped val ve body 16 being provided with radial wing parts 30, where the outer edges 32 have an inclined configuration complementary to that of the interior walls of said lower funnel-shaped bottom part 12 in the vicinity of said discharge valve 10. In practice the thickness of the radial wing parts 30 is about 2.5 mm - as the wing parts 30 is produced as integrated parts of the pear-shaped valve body 16 which preferably is made by injection moulding from a suitable plastic material such as polypropylene (PP).
    As stated in dependent claim 4 the valve body, which preferable is pear-shaped, may be provided with more than two radial wing parts 30, namely with a third radial wing part (not shown) being positioned in a midway position between said first radial wing parts 30 at the rear side opposite to said supply channel 9.
    Finally, it should be mentioned that in practice the shape of said valve body 16 may vary from a ball-shape to a pear-shape or a similar valve body - which, however, being provided with a number of radial wing parts the outer edges of winch being configured complementary to that of the interior w'alls of the lower bottom part 12 of the feed box 2.
    Preferably, said valve body being provided with at least two radial wing parts - but the number of wing parts may vary and also the positions of the radial wing parts may vary in dependence of the grain size of actual used feedstuff.
    In practice the number and the positions of said radial wing parts may support optimal function of the valve body by preventing the latter from overturning inside the lower bottom part 12 of the feed box 2.
    Therefore, it is of course very important that the shape and the position of the radial wing parts of the valve body in practice are suitable to support the wanted effect namely to prevent admittance of the feedstuff to the rear side of valve body in order to fulfil the purpose of the present invention and to be able to minimize the supply of feedstuff to said feeding positions.
