Dust removal type shot blasting machine for automobile chassis casting

The utility model relates to the technical field of shot blasting machines, and discloses a dust removal type shot blasting machine for an automobile chassis casting, which comprises a casing, a feed pipe is mounted on one side in the casing in a penetrating manner, a shot blasting device is mounted at one end of the feed pipe in the casing, and shunting pipes are arranged on the front side and the rear side of the shot blasting device. And one side of the flow dividing pipe communicates with a water inlet pipe. When external water supply equipment supplies water to the flow dividing pipe through the water inlet pipe, dust on the surface of the cleaned casting can be cleaned, waste water generated after cleaning is filtered through the filter plate and then falls into the waste water cavity to be cleaned through the drainage pipe, the filter plate can be pulled away, and therefore cleaning or replacement can be conducted; floating dust generated during shot blasting is sucked away by the fan in cooperation wi
