Abstract
Embodiments of the present invention relate to systems and methods implemented in a pothole patching system for creating a vacuum that pulls heavy particulate, such as gravel, out of a hopper. For example, according to an embodiment, a vacuum body having a vacuum chamber formed therein is positioned proximate to an opening of the hopper. A moveable slide gate is provided between the vacuum chamber and the opening of the hopper. The slide gate moves between open and closed positions for permitting and blocking communication between the vacuum chamber and the hopper. A reduction nozzle is provided between an air source and the vacuum chamber. Forced air flows from the air source, through the reduction nozzle, and into the vacuum chamber. The reduction nozzle reduces the pressure of the forced air entering the vacuum chamber, and thereby creates a vacuum in the vacuum chamber. When the slide gate is in the open position, this vacuum pulls particulate from the hopper.
