Abstract: A device for removing concrete debris from passages within modular blocks is disclosed. The device includes nozzles mounted to a plate at locations corresponding to the passages on the modular blocks. An actuator is secured to the block molding machine, supports the plate, and moves the plate from a retracted position to an extended position in close proximity to the conveyor. The nozzles are operatively connected to a source of compressed air and are arranged to enter within the passages of the modular block when the plate moves to the extended position. A control system directs operation of the device such that when a modular block reaches a predetermined location on the conveyor, the actuator moves the mounting plate to the extended position causing the nozzles to enter within the passages of the modular block and emit jets of compressed air to remove concrete debris from within the passages.
