1. A device for removing concrete debris from passages within modular blocks that have been formed by a block molding machine, the block molding machine including a mold, a conveyor for transporting modular blocks after molding, and a framework, each modular block including a top, a bottom, a front face, a back face, a first side, and a second side, the passages extending the entire height of the block from the top to the bottom, said device for removing debris comprising:
a. a plate having mounting holes defined therein and corresponding with the location of the passages on the modular blocks; b. an actuator secured to the framework of the block molding machine and supporting said plate, said actuator operative to move said plate from a retracted position to an extended position in close proximity to the conveyor; c. nozzles mounted within the mounting holes of said plate and operatively connected to a source of compressed air, said nozzles arranged to enter within the passages of the modular block upon movement of said plate to said extended position; and, d. a control system to direct operation of said device for removing debris, such that upon a modular block reaching a predetermined location on the conveyor, said control system energizes said actuator to move said mounting plate to said extended position causing said nozzles to enter within the passages of the modular block and emit jets of compressed air to remove concrete debris from within the passages. |
