1. A feed box (2 ) of the kind that e.g. via one or more supply openings (8) supply feedstuff portions from a feedstuff station via an endless tube conveyor (4) serving a plurality of preferably uniform feed boxes in a livestock stable, the feed box (2) being provided with a lower discharge opening (10) which via one or more down pipes is connected to a feeding position of one or more livestock, preferably pigs, the discharge opening (10) including a valve body (16) which is operatively connected with a common control wire (22) running along an upper end of the feed box (2), as said feed box (2) is further provided with a control device adapted for either allowing the operative connection with the common control wire (22) to open the discharge opening (10) by lifting the valve body (16), or to prevent the operative connection with the common control wire (22) from opening the discharge opening (10) by lifting the valve body (16), where said valve body (16) is provided with a number of radial wing parts (30) which divides a lower interior bottom part (12) of the feed box (2) in the vicinity of said discharge opening (10). 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. |
