Abstract
A device for cleaning a conveyor belt, whereby the conveyor belt has at least one surface and the device is responsive to a source of cleaning fluid and a source of pressurized air and is electrically powered by a source of electric power, includes a washer head assembly. The washer head assembly is removably mounted above the conveyor belt and includes a dual spray arm member for spraying the cleaning fluid onto the at least one surface of the conveyor belt. The washer head assembly also includes an air-driven motor for rotating the dual spray arm member, whereby the air-driven motor is responsive to the source of pressurized air and is operatively coupled to the dual spray arm member. Further, the washer head assembly includes a selectively adjustable air flow control valve for adjusting the rotational speed of the dual spray arm member. The conveyor belt cleaning device also includes cart-based equipment which is transported on a portable cart. The cart-based equipment includes an electric motor and a pressure pump for pressurizing the cleaning fluid prior to the cleaning fluid being supplied to the dual spray arm member of the washer head assembly. The cart-based equipment also…
