  • Method and apparatus for filling concrete bin
    Patent number: 7699065
    Abstract: A concrete wash-out bin includes a primary receptacle having a rim positioned at an elevation that exceeds the elevation of a discharge port of certain items of concrete-handling equipment. An auxiliary receptacle is positioned in leading relation to the primary receptacle and is hingedly mounted to the primary receptacle. The auxiliary receptacle has a position of repose where it is horizontally disposed at an elevation lower than the discharge port of the concrete-handling equipment and a discharge position where it is disposed in elevated and angled relation to the position of repose. The discharge position is effective to discharge the contents of the auxiliary receptacle into the primary receptacle. The auxiliary receptacle is repeatedly lifted and lowered as needed until the concrete-handling equipment is free of residual concrete or until the primary bin is full.
