Concrete Containment and Washout Apparatus
First Claim
1. A concrete containment and chute washout apparatus for use in association with a concrete truck having a concrete discharge chute with a main chute and an end chute hingeable connected to the main chute for rotation between a lowered positioned where the main chute and end chute form an elongated chute for concrete discharge, and a raised position where the end chute is positioned above the main chute, the apparatus comprising:
- a barrier plate having a peripheral sealing edge, and a fluid passage through said barrier plate at an inwardly position from said peripheral sealing edge;
a seal located along said peripheral sealing edge;
said barrier plate connectable to said end chute such that when said end chute is in the raised position, said barrier plate is positioned within said main chute with said seal providing a sealing contact between said peripheral sealing edge and an interior surface of said main chute forming a liquid tight barrier against the flow of material in said main chute;
a container positionable remotely of said barrier plate; and
a hose connectable to in fluid communication to said fluid passage and to said container for the passage of material from said main chute to said container.

Abstract
A method, a system and an apparatus for removing cement residue located within a concrete discharge chute and controlling the collection of debris and wash water, in a concrete mixing truck. The concrete discharge chute comprises a main chute and an end chute connected to the main chute via a hinged connection. In addition, a barrier plate having a rubber seal is connected to the end chute. When concrete discharge is completed, the barrier plate automatically prevents the discharge of debris by closing off the discharge chute when the end chute is raised into an upright and secured position. The barrier plate also has an optimally placed opening to control material flow along the main chute. The opening is fitted with a valve which may be connected to a drain hose to collect wash water into a collection tank securely positioned on the concrete truck.

7. A concrete containment and washout apparatus, comprising in combination:
-
a concrete truck having a concrete mixing drum; a concrete discharge chute attached to said concrete truck positioned to receive concrete from the mixing drum and discharge the concrete remotely of the mixing drum, said concrete discharge chute having a main chute and an end chute hingeable connected to the main chute for rotation between a lowered positioned where the main chute and end chute form an elongated chute for the discharge of concrete, and a raised position where the end chute is positioned above the main chute; a barrier plate having a peripheral sealing edge, and a fluid passage through said barrier plate at an inwardly position from said peripheral sealing edge; a seal located along said peripheral sealing edge; a pair of attachment brackets secured to opposite lateral sides of said end chute; a cross-bar having opposed ends removably receivable by said pair of attachment brackets such that said cross-bar extends transversely across said end chute; said barrier plate being fixedly secured to said cross-bar such that when said end chute is in the raised position, said barrier plate is positioned within said main chute with said seal providing a sealing contact between said peripheral sealing edge and an interior surface of said main chute forming a liquid tight barrier against the flow of material in said main chute; a container secured to said concrete truck remotely of said barrier plate; and a hose connected in fluid communication to said fluid passage and to said container for the passage of material from said main chute to said container.
