Abstract
An integrally mounted apparatus for washing out vehicle-mounted concrete mixing drums is disclosed. The washout apparatus includes an open-ended elongate, relatively rigid shaped hollow guide tube mounted in fixed relation to the support structure support of an inclined mixing drum and extending in fixed relation to the open end of the drum between the fins and charge hopper. A flexible hollow hose is threaded through the guide tube. The hose has a receiving end connected with a source of cleaning fluid under pressure and a discharge end which protrudes from the end of the guide tube as it ends inside the open end of the mixing drum. A forward hose stop is provided for preventing the hose from slipping back down through the guide tube and a rear hose stop is provided for limiting the travel of the discharge end of the hose outward from the end of the guide tube.
