This utility model provides a sandblasting machine with a self-cleaning function, relating to the field of sandblasting machine technology. It includes a sandblasting mechanism with an air-jet cleaning mechanism on its side and an adjustment mechanism inside. This utility model achieves high-efficiency cleaning by opening a valve on a connecting valve, allowing high-pressure gas to be delivered to an air-jet pipe via a connecting pipe and hose. The gas is then ejected through high-pressure nozzles distributed vertically on the air-jet pipe. A rotating motor is installed at one end of the air-jet pipe, driving the pipe to rotate and oscillate back and forth. This oscillation allows for increased air-jet cleaning range, facilitating efficient air-jet cleaning. High-pressure gas blows debris into the hopper and then discharges it through the discharge port, completing the cleaning process and ensuring internal cleanliness. This prevents damage caused by debris accumulation and backflow into the sandblasting equipment.
